Normal indoor humidity for a person in winter. Methods for increasing humidity

The moisture concentration in the premises should be constantly monitored, taking measures to normalize it in case of deviation from the recommended values. The norm of air humidity in the apartment must be strictly observed to maintain health and ensure a comfortable life. What is this norm and why is it important to comply with it?

A person cannot use his senses to determine the optimal humidity levels in a room. Non-compliance with the norm manifests itself in the physiological state gradually, over time.

The main signs of constant low moisture concentration in the air of an apartment are the following:

• dry skin;
• brittle nails;
• loss of hair elasticity;
• drying of the mucous membranes of the eyes and nasopharynx;
• weakness, rapid fatigue;
• disturbances in the functioning of the heart and blood vessels resulting from increased blood viscosity;
• allergic reactions from the respiratory system.

Most quickly, symptoms of trouble can arise in a child due to insufficient development of adaptive capabilities. Allergy sufferers react especially acutely to the moisture content in the air.

Excessive moisture content is also fraught with unpleasant consequences, which are primarily caused by the intensive proliferation of microbes, fungi, and the appearance of mold. As a result, apartment residents often begin to get sick, the room becomes acutely damp, and unpleasant odors appear.

It makes sense not to wait for the first symptoms high humidity or air dryness, but measure it regularly in the same way as we always monitor the air temperature indoors and outdoors.

Basic Concepts

You can determine whether the humidity in an apartment is normal using special devices. There are two main indicators that determine the amount of water vapor in the air:

• absolute;
• relative.

The absolute value indicates the mass of water in one cubic meter of air, measured in g/m3.

The relative indicator provides information about the ratio of the existing moisture concentration in the air to the maximum possible value at a given temperature. It is measured as a percentage.

Note! It is the relative humidity values ​​that are indicated in the standard tables. They are guided by taking readings from instruments or determining traditional methods.

How more value relative humidity, the higher the concentration of water vapor in the air. In this case, temperature is of particular importance. It is easier to tolerate high humidity at 20° than at 40°.

The following instruments are used to determine humidity:

• several types of hygrometers;
• psychrometers;
• combined devices.

For home use Compact devices are offered, equipped with the most simple, easy-to-understand scale. The instructions provide information on the rules of use and normal indicators for the air in the house.

What affects the microclimate in the room

The conditions for a person’s comfortable stay in a room are determined by several factors. We don't feel very good in rooms without sun rays, with poor sound insulation, not ventilated for a long time, containing a large amount of dust.

The quality of building materials used for finishing works, environmental friendliness of furniture, absence of background fumes from upholstery fabrics, floor coverings, interior items. Do not overload the rooms with household and computer appliances, audio and video equipment.

It must be remembered that all parameters are closely related to each other. It is necessary to monitor not only humidity, but also temperature, air ventilation, and lighting. The accumulation of dust and dirt should not be allowed, because even if humidity standards are observed in a contaminated room, bacteria dust mites will reproduce more intensively.

Note! Standard parameters of the microclimate in residential premises are regulated by GOST 30494-2011.

The temperature in a room is usually assessed quantitatively. Ideal temperature conditions range from 20 to 22 ℃. Sanitary requirements allow a decrease in the indicator in the cold season to 18 ℃. I wonder what Maximum temperature air in the apartment allowed in summer is 28 ℃. Warmer air takes us out of our comfort zone.

The standards stipulate the permissible temperature difference, which between walls and air cannot exceed 3 ℃, and between the floor and air - 2 ℃.

It's interesting that the same great importance V sanitary standards paid to the speed of air movement. In a living room in summer and spring it cannot exceed 0.3 m/s, in cold weather - 0.2 m/s. Consequently, sanitary doctors do not recommend creating drafts in apartments.

Indoor humidity standards

Acceptable humidity levels in premises are limited by the quantitative values ​​specified in SanPiN. During inspections, measurements are carried out in accordance with GOST methods. Acceptable values ​​for housing located in different climatic zones, differ, the required standards are not the same at different times of the year.

Summer and winter

Sanitary standards regulate the maximum relative humidity permissible in living rooms, which is 65% in summer, and 60% in the cold season.

Physiologists draw attention to the need to control minimum indicators, which at any time of the year should not be less than 40%. It is believed that ideal parameters for living rooms should have average values ​​between 40% and 60%.

In winter, when heating the room, whether a private house or apartment, the humidity can drop sharply due to dry air. This must be monitored, if necessary, turning on the humidifier, opening the window for ventilation or installing baths with water.

In separate rooms

Sanitary standards stipulate relative humidity in any living rooms, including bedrooms, without specifying their special purpose. However, pediatricians voice their opinion regarding the microclimate in the child’s room.

For some diseases, dry heat is useful, but it is usually applied not to the room, but to separate parts bodies. In this case, it is better to consult a doctor. Properly selected temperature and humidity parameters will promote rapid recovery.

The temperature in the child's room should not be higher than 25 ℃, optimally 22 degrees. It is recommended to ventilate the room several times a day. Newborns are especially vulnerable to violations of normative parameters. Low humidity makes them especially sensitive to microbes, and high humidity causes overheating and diaper rash.

For kitchens, bathrooms, combined bathrooms, toilets and pantries, relative humidity values ​​are not standardized by sanitary standards. They should not be allowed to become constantly waterlogged, as this will lead to the development of mold and bacteria. Therefore, hoods are installed in bathrooms and kitchens, and the temperature in pantries is monitored.

Relative Humidity Measurement

The need to periodically determine the relative moisture content in the air of an apartment is no longer in doubt. The easiest way to do this is to buy a special device for home use. It is easy to use and comes with explanatory instructions. Regardless of the operating principle, it can be used to easily and quickly obtain the value of interest and compare it with the standard.

If you don’t have a device, but you need to determine the humidity level, you can use traditional methods. They give a fairly complete picture of the microclimate in the apartment.

The simplest method is to hang wet laundry in the room. If it dries in 1.5 hours, then the air in the room is too dry.

It is useful to observe indoor plants. With low humidity, the soil in pots quickly dries out and the tips of the leaves begin to turn yellow.

Interesting advice on how to determine moisture content using an open flame of a candle or lighter. It is believed that if the flame burns vertically, then the humidity is normal, and fluctuations of the fire from side to side supposedly indicate a lack of moisture in the room. From the point of view of the laws of physics, the idea is very dubious. Flame fluctuation can be caused by several factors, of which moisture concentration ranks last.

Experiments with water and pine cone

A simple method using water in a cup or glass is reliable. The container with liquid must be placed in freezer, stand for several hours until the water temperature reaches 5 ℃. If you place the cup in the freezer for a few minutes and the water freezes, it’s okay, you can conduct the experiment with ice.

Then the cup needs to be placed on the table in the room and observed. Condensation will appear on the walls very quickly. The observations are further interpreted as follows:

• with rapid drying - reduced humidity;
• within 5 minutes there was no change in the condensate - the humidity is normal;
• Drops flow down the walls of the cup - the humidity is increased.

An interesting way to determine moisture concentration requires fir cone. It should be placed in a room away from heating equipment, observe her for a few minutes. If surrounded by dry air, the cone will open, and if surrounded by humid air, it will shrink tightly.

Once the humidity level has been determined, adjustments may need to be made.

Ways to increase

In an apartment with dry air, you need to do wet cleaning often, you can leave wet towels on the radiators, and start an aquarium if your household has no contraindications.

The easiest way is to place containers of water near the wall at least overnight. It is advisable to turn on air conditioners and heaters in such apartments as rarely as possible. You can plant indoor plants that require frequent watering and regularly monitor them and irrigate the foliage.

If you are ready to invest a little money in ensuring a normal microclimate in your apartment, the easiest way is to buy special humidifiers. They are inexpensive, and their effectiveness is beyond doubt.

Ways to downgrade

You can reduce the concentration of moisture in an apartment by frequent ventilation, installing an automatic microclimate control system, checking the efficiency of ventilation, and installing additional fume hoods in the kitchen and bathroom. Of course, you should make timely repairs in the apartment, monitor the tightness of pipelines, and do not dry washed laundry indoors.

Ultimately, any deviations in the microclimate can be easily eliminated. The main thing is to remember the need to control humidity levels and other important factors that ensure a prosperous living environment.

Most people, first of all, pay attention to the air temperature, forgetting about such an important indicator as humidity. But the feeling of heat or cold, general well-being, the condition of plants and the safety of household items depend on it. What is the normal level of air humidity in an apartment, how does it affect the human body and more.

Problems arising from lack or excess moisture

Dry indoor air provokes increased moisture loss through the skin and respiratory tract. This can lead to such unpleasant consequences, How:

• decreased elasticity of hair, nails and skin, accompanied by the appearance of microcracks, wrinkles, peeling, dermatitis;
• drying of the mucous membrane of the eyes, the symptoms of which are itching, redness, and a feeling of “sand”;
• thickening of the blood, leading to a slowdown in blood circulation, weakness, headaches, decreased performance, and increased stress on the heart;
• an increase in the viscosity of gastric and intestinal juices, causing a slowdown in digestion;
• drying of mucous membranes respiratory tract, the consequence of which is a weakening of local immunity and an increase in the frequency of acute respiratory viral infections;
• an increase in the amount of respiratory allergens in the atmosphere, which should normally be bound by liquid droplets.

Excess moisture in the air creates acceptable conditions for the growth of mold, fungi, and bacteria. As a result, you may encounter the following problems:

• respiratory diseases - chronic runny nose, bronchitis, asthma, allergies; feeling of stuffiness or dampness in the room;


• unpleasant smell due to the proliferation of pathogenic microorganisms;


• increasing the drying time of washed laundry.

Excessive or insufficient amount of moisture in the house has a bad effect on the condition of home furnishings. Plants dry out or begin to rot, wooden furniture and parquet become deformed or “shrink,” paintings fade, paper products lose their structure.

Factors affecting humidity

The main factor influencing indoor humidity is temperature. If you ventilate a room in winter, the air will become fresher, but less humid.

Reduce air humidity:

• heating devices;
• air conditioner;
• constant ventilation at outside temperatures below -10C
• interior items, especially upholstered furniture, toys, carpets.

Any sources of water and steam increase air humidity:

• aquarium;
• houseplants;
• wet laundry;
• containers with boiling water;
• faulty water pipes and plumbing.

Constant condensation on the windows indicates elevated level humidity in the room.

Indoor humidity level:

• warm period - 30-60%, maximum permissible - 65%.
• cold period - 30-45%, maximum permissible - 60%.

Young children have increased heat exchange processes, so they are especially sensitive to non-compliance with microclimate parameters. The ideal air humidity in a children's room is 50-60%, and if the child is sick with ARVI, it is recommended not to drop below 60%.

Indirect signs of low indoor air humidity are drying out the tips of plant leaves and electrical discharges emanating from synthetic clothing.

How to regulate air humidity?

At any time of the year, normal air humidity in the apartment should be no less than 40% and no higher than 65%.

Ways to reduce humidity:

• frequent ventilation of premises;
• installation of exhaust fans;
• use of air conditioners and heaters;
• serviceable pipes and plumbing;
• refusal to dry clothes in the room;

How to increase the humidity in a room:

• the presence of an aquarium or decorative fountain;
• minimal use heater and air conditioner;
• hanging wet towels on radiators;
• periodically spraying water from a spray bottle;
• using a humidifier;
• regular wet cleaning;
• cultivation large quantity indoor flowers.

Air humidity in the house - important parameter, affecting both the well-being of residents and interior items. Normally, this figure ranges from 40 to 60%. It is especially important to monitor the humidity in rooms where children and people with respiratory diseases spend most of their time. To regulate the moisture concentration in the air, it is convenient to use household humidifiers and dehumidifiers.

What are the health risks of dry air?

If the air in the room is dry, then the “transportation” of oxygen into the circulatory system is difficult. As a result, a person constantly feels drowsiness and increased fatigue, while often not understanding where the poor health came from. When a person breathes dry air for a long time, his susceptibility to various infections increases, hence the appearance of a runny nose in the morning. Due to dry air, the nasal mucosa and bronchial tube cannot clean themselves as effectively as with air of normal humidity. As a result, the body easily succumbs to infections and various respiratory diseases. This is especially true for the little ones, whose immunity is weaker than that of adults. It’s not for nothing that even in a newborn’s room it is recommended to hang wet laundry to make the air more humid.

And these are only external manifestations; in addition, our overall well-being worsens: drowsiness appears, attention becomes more distracted, and due to the drying out of the nasal mucosa, viruses and bacteria easily enter our body. In a room with low humidity, we inhale more dust, which can remain in the air for hours, bouncing off various surfaces. A household humidifier will help eliminate all these consequences of dry air.

Humidity and air conditioning

IN summer period The main enemy of humid air is the air conditioner, which, like a vacuum cleaner, pulls moisture out of the room: the moisture condenses on a cold heat exchanger and is removed from the room to the street. Industrial ventilation systems (often used in public places, offices, and factories) use air intakes to pump outside air into the premises, but it can also turn out to be dry if this happens in winter or in the summer heat. Therefore in in this case You can't do without a humidifier.

Humidity in winter

In addition to the air conditioner, various household appliances can be enemies of humidity: TVs, computers, etc. But the most formidable enemy of air humidity is, of course, central heating. It is because of this that in winter the air humidity in our apartments reaches the most critical level - less than 20% (this figure is even lower than in the Sahara Desert). "Helps" central heating and frost. Most of us know that the lower the air temperature, the less water vapor it can contain. Thus, in frosty street air the absolute moisture content is minimal, and when this cold air and enters the room and heats up, the relative humidity tends to zero.

Dry air is dangerous not only for people, but also for pets and indoor plants. In addition, furniture, wood products, and parquet also need to maintain a balance of temperature and air humidity. But the ones who suffer the most from exposure to dry air are young children, whose bodies are not yet ready for such aggressive effects of dry air.

A humidifier will help solve all of the above problems with dry air, both in summer and winter. U Venta company exist various models, intended for different areas service. All models both humidify and purify the air from house dust and allergens. In addition, Venta air purifier humidifiers can scent room air.

Indoor air humidity

The air parameters maintained in a building are important for human life, the safety of building structures, and the uninterrupted operation of equipment. In fact, humidity is the content of water vapor in the air. There are two types of this parameter:

1. Absolute (moisture content) – the actual mass of water in the form of steam in 1 m3 of air. It is measured in kg/m3 and is used in climatic and thermal calculations.
2. Relative - the percentage ratio of the absolute value to the saturated vapor density at a given temperature (this is the maximum possible moisture content at this temperature). This parameter determines how close the moisture content is to the maximum (100%). This value is used to analyze and determine the influence of moisture from the air on humans and the environment.

The optimal humidity in a room is determined by its purpose.

Indoor air humidity standards

Basic air parameters (temperature and humidity) are standardized. There are their limit values, above and below which people experience discomfort, or there is a negative impact on structures and equipment. The humidity level in the room is indicated in sanitary and building regulations for each type of building. For example, for residential buildings and apartments in GOST the following values ​​are indicated for living rooms in the warm season:

During the cold season:

For toilets, bathrooms and kitchens, the values ​​are not standardized, but it is advisable to take them the same as for living rooms.

For public buildings the meanings are the same. In rooms where people are present, the limits of relative humidity are determined by comfort, but the effect of moisture on building materials, antiques and equipment should also be taken into account. There are the following recommended humidity parameters:

• For rooms with parquet and other products from natural wood– 45–65% at any time of the year.
• For paintings, antiques, books – 50–60%.
• Computer and electronic equipment – ​​20–60%.

Normal indoor air humidity in winter, if there are people with respiratory viral infections in the room, can reach 70–75%.

The influence of humidity and methods of its regulation

Why is it important to maintain humidity within specified limits? How does an increased or decreased value of a parameter affect people, equipment, wood, and building materials? Let's take a closer look. Low humidity affects the following:

• For people – drying of the skin and mucous membranes. Dry mucous membranes (nose, larynx, eyes) cause an increased incidence of respiratory infections, so during illness it is necessary to maintain high humidity, especially in winter. Also, low humidity provokes static electricity, which is unpleasant for people.
• On wood – drying and cracking of parquet, furniture, antiques.
• On equipment - the appearance of the same static electricity, which can damage electronics.

High humidity has the following effects:

• For people – increased feelings of cold or heat, stress on the respiratory system.
• On building structures - the formation of condensation on windows and walls during the cold period, which leads to fungal infection and destruction of materials.
• For electronics there is also an increased likelihood of condensation forming, which is unacceptable for technology.

Relative humidity depends on air temperature, so this parameter outdoors and indoors at the same time can differ significantly. If the moisture level does not fit into the norms, it is adjusted in the following ways:

• Boost – humidifiers. They are released for various purposes and performance for domestic and industrial applications.
• Reduction – dehumidifiers. A split system works just like an air dehumidifier if this function is available or when operating for cooling.

Maintaining proper humidity in your home will help avoid frequent colds, damage to building materials and structures, and equipment failure. If necessary, it is advisable to use regulation devices even in domestic conditions.

Dry air is also harmful to skin health. When you stay in a dry room for a long time, your skin becomes like rubber. The reason is that due to lack of moisture, evaporation from the skin accelerates. Therefore, it quickly becomes rough and dry.

The simplest and most effective way to increase the body's resistance to infections in dry rooms, as well as increase the elasticity and healthy appearance of the skin, is drinking water. A few glasses of natural water a day give your body a big boost of energy and boost your immunity.

What should be the air humidity in the apartment?

IN modern society People increasingly began to think about the quality of the air around them. And if on the street due to the abundance of exhaust gases and natural features it is impossible to influence the airspace, then own home You can freely create a comfortable and healthy atmosphere. That is why the level of humidity in a residential area began to be carefully studied by people who care about the state of their health and home. IN Lately Various air purifiers and air conditioners have gained popularity. Very often, people, worrying about the temperature of the atmosphere and its cleanliness, completely forget about the level of humidity. Namely, this parameter has an active effect on the condition of human skin, ease of breathing, sensation of space temperature, and the service life of household items.

What is affected by the level of humidity in the apartment?

The state of air humidity is based on indicators of the saturation of the atmosphere with water-vapor masses. In order to determine the percentage of air humidity masses in a room or building, you should use the following calculations:

• the absolute indicator of air humidification is determined from the number of grams of water per cubic meter of air space;
• the relative indicator is determined after calculating the absolute indicator and looks like a percentage of the maximum acceptable indicator in a particular room.

To determine the comfort level of humidification in an apartment, you should use a relative parameter expressed as a percentage. For what purposes should moisture parameters be taken into account? When. if the atmosphere is excessively dry, then there is a high probability negative influence on external condition human health. Namely: constant dryness and flaking of the skin appears, hair becomes less elastic and manageable, nails become susceptible to separation and brittleness, the mucous membrane of the eyes quickly dries out, causing fatigue and drowsiness, the blood in the vessels thickens and blood circulation is impaired, metabolic processes and metabolism slow down. A low level of humidity in an apartment reduces the level of human immunity, since microbes and irritants penetrate more easily through the unmoistened mucous membrane of the respiratory tract. People living in rooms with dry air are most susceptible to colds and allergies. Except negative impact per person, low indoor humidity, the norm of which is significantly deviated from the necessary one, affects the condition of household items.

Quick-drying plants and cracked wood floors are the consequences of a lack of moisture control in a space.

Excessive humidity in the room also affects people and surrounding objects. Namely, an abundance of water in a space tends to make a person feel drowsy and unfocused, and also makes it difficult to breathe. The abundance of water in the atmosphere negatively affects household appliances and electronics. Metal parts quickly begin to rust and become unusable.

Reasons why deviations from the norm occur

First of all, the temperature of the space has a huge impact on the state of the air in the room. It is believed that high temperature promotes greater retention of water vapor. That is why the relative humidity of the air at a warm temperature in the space will have the strongest concentration of vapors. IN winter time When ventilating a room, the incoming cold air has very low relative humidity, despite being fresh and pleasant to breathe. The normal temperature to maintain comfortable humidity will be no more than 20 degrees Celsius. One should also take into account the fact that pieces of furniture also affect the water level in the atmosphere. Soft toys, stuffed sofas and armchairs take up a lot of water. In winter, the relevance of using means that regulate indoor humidity increases significantly, since in addition to cold, dry winter air Heating devices and air conditioners remove all moisture in the apartment.

The following factors influence the increase in vapor in space and the creation of a wet steam room in an apartment:

• presence of an aquarium with fish in the house;
• sources of moisture such as indoor plants;
• boiling water in the kitchen;
• drying wet linen and clothes;
• leaks in the plumbing system;
• condensate on pipes;
• holes in the roof.

If there are such situations and problems in the room, then in this case we can say that there is high humidity. Also, evidence of a deviation from the standard level towards an increase in water in the atmosphere is evidenced by drops of condensation on the windows.

Indicators of indoor humidity standards

What humidity in an apartment can be considered normal? How should it be in a nursery? Before rushing out to buy a humidifier, you need to figure out how the humidity in a living space will be considered optimal for living. Perhaps, after some calculations, we can come to the conclusion that the room does not require additional steam generators at all. As a percentage, comfortable air humidity in the house should range from 30 to 60 percent. At the same time, the maximum possible and permissible value of water per cubic meter of a house should not exceed 65%. However, assumptions have been made based on climate and temperature characteristics in environment and this figure was increased to 75% water.

The amount of water in the atmosphere should be determined in the bedroom, living room or other living room, except for such spaces as the bathroom, toilet, pantry, corridor. The parameters of the amount of moisture for specific items that may be in the apartment should not be excluded from attention, namely:

1. If there are antiques in the house, then it is important to control the humidity level at 50%;
2. For home appliances, a fifty percent amount of water will also be comfortable;
3. Books are best stored in a specialized room with a relative humidity of no more than 60%;
4. Tropical and indoor plants love high humidity and for them you can specially organize a place on the loggia with an amount of moisture of almost 100%.

Moisture control for baby

Many parents who are concerned about their child’s breathing condition install specialized air humidifiers in the children’s room. However, what should the air humidity be for children? Small children and adolescents are extremely often susceptible to various infectious and viral diseases.

This may also be due to drying out of the mucous membrane of the respiratory tract. Children's bodies are most susceptible to temperature and atmospheric changes and changes in the internal climate of the room. It is important to maintain a constant temperature, air purity and humidity in the children's room to eliminate reactions to interseasonal changes in humidity in the room. The level of humidity in an apartment for a child’s room will be at least 50 percent, but not more than 70. The higher the humidity in a child’s room, the easier it will be for him to deal with colds and the flu. Additional hydration of the mucous membranes of the child’s respiratory system helps to quickly flush out pathogenic bacteria and microbes from the body.

Determination of relative air humidity

In order to determine the amount of water in a space, special devices were invented - hygrometers. At the moment there is no problem purchasing one for home use. Such devices can be ordered in an online store and are relatively inexpensive. To meet the needs of consumers, hygrometers were invented to measure humidity using electricity, chemical analysis or condensation. In some cases, you can purchase a watch dial combined with a hygrometer or an air temperature meter.

It is absolutely not necessary to purchase an overly expensive and accurate device for your home; errors of 5 percent will not be considered severe disadvantage. It is important to consider the location of the device, namely, it needs to be installed as far as possible from sources of moisture. In this case, the indicators will be most accurate. There are also folk means of measuring air humidity. These include the method using a fir cone. If you bring a cone from a Christmas tree into your house and place it away from heating systems, then after a few hours you can determine by the reaction the presence or absence of water in the atmosphere. If the scales of the cone are closed and smoothly adjacent to each other, then such a reaction indicates humid air. If the cone opens, then it is believed that the atmosphere is very dry and the space needs moisture.

How to regulate water levels in an apartment?

There are several ways that can help easily, stylishly and without extra costs adjust the moisture level in the space. What kind of humidity can there be in an apartment without proper control? In order to increase the amount of water per cubic meter of space, you can do the following:

• buy an aquarium with fish;
• hanging wet towels on heating appliances;
• using a spray bottle with water;
• increasing the number of wet cleanings;
• purchasing a large number of indoor flowers for the room;
• using a special air humidifier or steam generator.

If, on the contrary, it requires reducing the amount of water per cubic meter of space, then in this case you need to use the following methods:

• minimize the use of heaters in the apartment;
• dry laundry and clothes on the balcony or in the bathroom;
• install additional device for extracting moist air from the kitchen;
• increase ventilation of rooms;
• installation of a special air dryer.

To control moisture in the air on a budget, it is enough to ventilate the room in a timely manner, and in the case of dry air, place containers of water around the room. For complete and reliable control, it would not be superfluous to purchase specialized devices for climate control of the air space of an apartment, such as air purifiers, humidifiers, air conditioners, and climate control units. Controlling your own comfortable breathing is the concern of every self-respecting person.

Humidity: what, why and how

I understood a little about the issue of air humidity and why it is so important.

Humidity can be absolute (how much moisture is in the air) and relative (how much moisture is in the air as a percentage of the maximum possible).

For humans, the optimal relative humidity is 40-60%:

• If the relative humidity is high, then sweat does not evaporate well from the skin (the air is already saturated with moisture), and a person does not cool down in the heat. He becomes hot and stuffy compared to the situation in dry air of the same temperature.
• If the relative humidity is low, the air unsaturated with moisture begins to suck moisture from surrounding objects. Including from human skin and mucous membranes, which become dry and crack. A runny nose occurs as an attempt to moisten the mucous membranes in the nose. This is especially bad for children. Houseplants also do not tolerate low importance well - their leaves dry out.

The key physical fact is that the maximum possible amount of moisture in the air (of which % relative humidity is calculated) depends on its temperature. The higher the temperature, the more moisture the air can hold. Accordingly, if the air is heated, then at the same absolute humidity, its relative humidity will drop (now the % is taken from the larger indicator). Conversely, if the air is cooled, its relative humidity will increase.

Examples and consequences:

• On the street during the day, air humidity is lower than at night (easy to verify by looking at the humidity readings for any day). Precisely because during the day the air temperature is higher than at night. Sometimes at night the air temperature drops so much that the relative humidity approaches 100%. Since 100% is the limit, then excess moisture leaves the air by condensation. This is called "dew".
• In winter, the air humidity outside is 50-90%, which is relatively comfortable for humans. However, when air from the street enters the apartment (and all the air in the apartment ultimately comes from the street), it heats up to room temperature(and this is plus 30 degrees), which leads to a sharp drop in its relative humidity to the level of 20-30%, which is already significantly below the norm. This explains why the problem of dry air in the apartment arises in winter. It's all about the temperature difference between the house and the street (while outside the humidity is almost always normal).

For these reasons I bought myself a humidifier. I haven’t tested it yet - I haven’t gotten around to it, and it’s not cold outside yet.

This site will help you with information that will be useful at the right time and for a specific case. For example, you don’t know how to make bread sourdough at home? Or do you want to know what the symbols on a clothing label mean? This site will tell you and show you everything on these topics.

What should be the humidity in the room (normal)

A person will feel comfortable if the relative air humidity is in the range from 40 to 60%.

Dr. Komarovsky writes: “For a healthy child, the humidity should be at least 60%, for a patient with a respiratory infection - at least 70%. More than 80% is not necessary.”

Indoor plants and pets also suffer from lack of moisture.

1. Using the thermometer of Assmann's ipsychometric table. Record the temperature on a thermometer installed in the room. After this, wrap the end containing the mercury with a damp cloth. After 5 minutes, check the result. If it turns out to be higher than the previous one, it means that you did not wet the cloth very well. In this case, repeat the process. Write down the result. Then consult the Assmann chart. In the left column of the table are the values ​​of the dry thermometer, at the top is the temperature difference in degrees between the dry and wet thermometers. The temperature intersection point will show the approximate humidity.

The most optimal and modern way increase the humidity in the apartment - buy an air humidifier. This device is designed mainly for rooms up to 150 m³. Water is poured into a special container of the humidifier, which evaporates when the device operates.

• steam
• ultrasonic

How to increase humidity with folk remedies

1. The most common way is to place a wet towel or sheet on the radiator. The fabric heats up and the water begins to evaporate. When the towel is dry, you need to wet it again.
2. If you don’t want to go to the bathroom every time the fabric dries, you can place containers of water on the radiators. In this case, you will need to add water every few days.
3. From containers with water placed on pieces of furniture (on cabinets, for example), evaporation occurs more slowly, but the humidity still increases.
4. You can place a bowl of water near the battery. The end of a bandage folded in several rows is lowered into it. The other end is located on the battery. The water constantly rises up the bandage and evaporates from the heat.

Air humidity in an apartment is a very important indicator, the value of which will determine the well-being of the residents. Any deviation from the norm, be it an increase or a decrease, is very noticeable by a person and can lead to a large number of troubles, for example, deterioration in health, discomfort, and more. In order to avoid this, you simply need to know the norm of the amount of moisture in the air in a particular room and in different time of the year.

What is air humidity

What is meant by the phrase “air humidity”? What we mean in this case is the content of water vapor in the air, because it is constantly present there, regardless of the time of year and temperature. However, its amount may fluctuate up or down. And this already depends on a large number of factors. For example, in winter, heating pipes dry out the air greatly. And if there is a leak somewhere in the house for quite a long time, this can significantly increase the level of air humidity in the rooms.
To clearly see that there is moisture in the air, you can conduct a small and very simple experiment. Take a plastic one or glass bottle and fill it with water. Place the container in the refrigerator for a couple of hours. After the liquid has cooled, place the bottle on the table and watch what happens next. It will be covered with droplets of water, or rather, condensation will form on it.

Consequences of low and high air humidity in the apartment

The thing is that if the air in the room contains too much moisture, this can lead to the appearance and rapid development of fungi, mold, pathogenic microorganisms, as well as various insects. Such a deviation from the norm causes rapid damage to pieces of furniture, especially antique ones. And a person does not feel comfortable in such a room. You can understand that humidity is increased by looking at the windows in the cold season. A large amount of condensation will accumulate on the glass.
But if the humidity is less than the required value, then this also does not have the most favorable effect on the functioning of the human body. The thing is that excessively dry air contains a huge amount of dust and pathogenic microorganisms, and they will be the cause of the development of some quite serious diseases, in particular ARVI, upper respiratory tract disease, various forms of allergies, and so on. Also, human hair and even skin can suffer from a lack of moisture in the air. For example, the hair will become dry, brittle and lose its shine, and the skin will begin to peel and become very sensitive.

How can you measure indoor air humidity?

For a long time, people have come up with a large number of methods that can help understand what humidity is in a particular room. So, the most reliable way to establish this value is to measure it using a hygrometer, a device specially designed for this purpose. It is very easy to use, and the amount of moisture content in the air that it will show will be accurate.
But there are cases when it is simply impossible to use a hygrometer, and it is necessary to know the air humidity in the room. Then you can use methods invented quite a long time ago.

1. way. You will need a glass glass, preferably with smooth transparent walls, plain water and a refrigerator. Fill the glass with liquid and place it in the refrigerator to cool for about an hour. After this, remove the container and place it away from heating devices. Watch him for five minutes. If droplets of moisture appeared on the outer walls and quickly evaporated, then the humidity is low. The condensation remained and began to flow down, this indicates excess moisture. Normally, condensation should remain on the walls of the vessel for five minutes.
2. way. Take the pine cone and place it away from the sun and heating devices. If it starts to close, there is little moisture in the air, if it opens, there is a lot.

Normal air humidity in a children's room

It is especially important how much moisture is contained in the air of the room in which the child lives, and especially if it is an infant. Most people seriously think about such indicators as air humidity only after they have a small child.
The norm is 50–60 percent. Pediatricians advise maintaining the moisture level for infants within these limits. The thing is that due to the presence of a large amount of dust in the dry air, the child may begin to snot. He may also develop much more serious diseases. You can often observe a situation where it seems that the children's room is always warm, there are no drafts, but the baby is constantly snotty, which greatly complicates his life, since not only breathing is difficult, but also the process of eating or drinking water.
However, an excess of moisture in the air will not have the best effect on the baby’s well-being. Due to the presence of a large number of spores of moldy fungi in the air and due to a violation of heat exchange. That is why it is very important to maintain normal air humidity levels in this room. The best solution would be to purchase a humidifier or make one yourself. And if necessary, it is worth buying a desiccant.

Air humidity level in living rooms

In rooms such as the bedroom, kitchen, living room, it is also very important to maintain air humidity within the normal range, which is 40–60%. If there is normal air humidity in living rooms, this will have the most favorable effect on human health and vital activity. And also furniture, household appliances, a computer, a TV will last in this case much longer than, for example, with high humidity in the room. By the way, for many pets it is also very important that this indicator is within the normal range, and deviation from it does not have the best effect on their well-being.
However, high humidity is often observed in the kitchen area.

Normal humidity and temperature in the room

This is due to the fact that a lot of moisture evaporates when cooking food. Washing dishes and frequent wet cleaning also cause an increase in humidity. However, there is a way out of this situation. The most effective way would be to install a hood and frequently ventilate the kitchen area. It is also recommended to ensure that there are no water leaks anywhere.

What air humidity should be in the bathroom?

The moisture level in the bathroom is also very important. Indeed, in a given room it is often excessively high. And as mentioned above, excessively high air moisture can lead to the formation of mold on the walls. And also in a warm and humid environment, various insects feel great, for example, wood lice, centipedes and even mosquitoes.
The level of moisture content in the air in this room will be slightly higher than in other rooms. 45–70% - this is exactly what the humidity in the bathroom should be. To achieve this, you need to think through a ventilation system or install hoods during the renovation. It’s also great if the bathroom has a small window with a window for ventilation. But if there is none, then you should open the door to this room more often and make sure that the floors and walls are always dry. And also promptly eliminate leaks, if any.
If you properly care for your bathroom, you can even put wallpaper on the walls and forget about mold and wood lice altogether. If nothing helps and the humidity is still higher than normal, then purchase a desiccant. It will certainly help get rid of this problem.

Normal indoor air humidity in winter

In winter, as a rule, most often indoor air humidity is slightly below average, approximately 40–45%, which is the norm. This is due to the fact that in winter rooms are ventilated much less often, and today’s popular plastic windows cause disruption of natural ventilation. Heating radiators and additional heating devices dry out the air very quickly.
Due to the above reasons, the moisture content in the air can become catastrophically low. However, to prevent this, a number of measures need to be taken. The most reliable option would be to purchase an air humidifier in a store, but this pleasure is not cheap. The following will come to your rescue: regular ventilation, drying clothes indoors, and growing special indoor plants. You can also place wide-necked containers in the rooms, which should be filled with plain, clean water, but it will need to be regularly replaced once every 2 days. If you need to raise the moisture level very quickly, you can hang it on hot battery heating wet thick towel. The main thing is not to overdo it, otherwise instead of a lack of moisture in the air you will have an excess of it.

What should be the air humidity in the apartment in summer?

Typically, during the hot summer months, the moisture content in the air in rooms increases. 40–65% is considered the norm, but often this figure in many residential premises is much higher. And this can have a very bad effect on a person’s well-being, because due to the high concentration of moisture in the air, heat exchange disturbances occur. Imagine this: it’s hot outside, all the windows are closed, something is cooking on the stove, things are drying. A person is exhausted from stuffiness and even a cool shower can only slightly alleviate the suffering.
In order to avoid increasing the amount of moisture in the air indoors, you just need to regularly ventilate the rooms, and it is best to keep the window open throughout the day. The situation can also be corrected by installing hoods in the kitchen and bathroom. If possible, you should also hang wet clothes outside or on the balcony.

Ideal indoor air humidity

Of course, very few people can boast of ideal humidity levels in an apartment. However, this is always worth striving for, especially if small children, elderly or sick people who have weakened immune systems live in the apartment. In this case, purchasing a hygrometer and constantly maintaining required quantity moisture in the air is a must.
An indicator such as air humidity is very important and therefore should not be ignored. And by ensuring normal moisture concentration, you will make the living of people in this room more than comfortable, increase the service life of furniture and household appliances. And your beloved pets will feel just wonderful. So the forces applied to raise or, conversely, reduce the concentration of moisture in the air will not be wasted.

SNiP and GOST

Temperature standards for public and administrative buildings

OPTIMUM AND ALLOWABLE STANDARDS OF TEMPERATURE, RELATIVE HUMIDITY IN THE SERVICE AREA OF PUBLIC AND ADMINISTRATIVE BUILDINGS (GOST 30494-2011, SANPIN 2.1.2.2645-10)

Season: Cold*:

	Air temperature, °C		Resulting temperature, °C		Relative humidity, %
	optimal	acceptable	optimal	acceptable	optimal	acceptable, no more
					Not standardized	Not standardized
Bathrooms, showers					Not standardized	Not standardized

Season: Warm*:

*A warm period of the year is considered to be a period in which the average daily outside air temperature is above 8 °C. Source: GOST 30494-2011.

The cold period of the year is considered to be a period in which the average daily outside air temperature is below 8 °C. Source: GOST 30494-2011.

This standard adopts the following classification of public and administrative premises:

• premises of the 1st category: premises in which people, lying or sitting, are in a state of rest and relaxation;
• premises of the 2nd category: premises in which people are engaged in mental work and study;
• premises of category 3a: premises with large numbers of people, in which people are mainly in a sitting position without street clothes;
• premises of category 3b: premises with large numbers of people, in which people are mainly in a sitting position in street clothes;
• premises 3 in category: premises with large numbers of people, in which people are mainly in a standing position without street clothes;
• premises of the 4th category: premises for outdoor sports;
• premises of the 5th category: premises in which people are scantily clad (locker rooms, treatment rooms, doctors' offices, etc.);
• premises of the 6th category: premises with temporary occupancy of people (lobbies, dressing rooms, corridors, stairs, bathrooms, smoking rooms, storage rooms).

First of all, human health depends on the humidity in the room, and secondly, the normal growth and development of plants. If there is not enough moisture, the furniture may deteriorate. If the humidity in the room is constantly elevated, this will lead to the appearance of mold and mildew. If the air in the apartment is dry, dust and dust mites may appear, to which many children are allergic.

Methods for measuring humidity in an apartment

What should the humidity be? There are standards for air humidity in each room according to GOST.

There is a special device for measuring air humidity in an apartment, it is called a hygrometer. The screen shows the coefficient of humidity and room temperature. In summer, the humidity does not need to be increased artificially, but in winter this must be done. In summer, the humidity in the room is most often normal.

Methods for determining humidity:

• Air humidity is determined using a device and a table of standards. It is necessary to identify the correlation of norms.
• You need to collect water in a container and put it in the refrigerator. The container must be transparent. After 3 hours, it must be pulled out and left in some room, but away from heating systems. Observation should last 5 -10 minutes. If the walls of the container fog up and then immediately dry out, then the air in the room is dry. If the glass remains fogged, then the humidity is average. If streams flow down the glass, it is high.
• What is the air humidity in the room can be determined using a spruce branch.

  Air humidity in the apartment: normal

  Its length should be 25-30 cm. The branch is attached to the board and the position of the loose part of the spruce is marked with a pen. If the room is humid, the branch will drop. If not, then the air is normal. You need to observe the position of the coniferous branch every day and note changes. The further the branch descends, the higher the humidity.

• You need to take a fir cone and place it away from the battery and look at its scales. If they begin to shrink, then the air humidity is high; if they fluff, then dry air predominates in the room. If it remains unchanged, then the humidity level is normal.

When to increase the humidity in an apartment:

1. In winter.
2. When a child has a dry cough.
3. If it becomes difficult to breathe.
4. When a child experiences an exacerbation of allergies.

Ways to increase humidity

• A traditional humidifier has a built-in fan that blows air through a bowl of liquid. But air humidity reaches no more than 60%, and the apartment will be noisy.
• Steam - there are special humidifiers in which water boils and steam comes out, thereby increasing humidity. With its help you can achieve normal room humidity.
• Ultrasonic – This humidifier also turns liquid into vapor using a unique membrane. Also, many models destroy microbes present in the air, which will make it cleaner.

How long will it take to humidify an apartment using humidifiers? This will take approximately 2-3 hours.

Traditional methods of increasing indoor humidity

The air in the room will become humid if you place a wet cloth on the heating appliances. It will begin to warm up, and the water from it will evaporate. How many times a day should you wet it? This should be done 3-5 times a day.

You can place cups of water on the windowsills under the radiators, from high temperature the water will evaporate.

To increase air humidity, you need to dry your laundry indoors.

Indoor plants help maintain normal moisture levels.

You can install an aquarium.

After taking a shower or bath, leave open door, humid air will enter other rooms.

How to reduce humidity in an apartment?

Using a dehumidifier. It works due to temperature differences. Excess moisture turns into condensation. When choosing a device, you should pay attention to its performance. They can absorb moisture up to 300 liters per day. Such devices are installed in combined bathrooms and kitchens if they do not have a normal hood.

Ventilate all rooms in the apartment as often as possible, this will help maintain air humidity standards. Fresh air is very good for health, especially in times of illness. In a ventilated room, bacteria spread more slowly.

In bathrooms, ensure that hoods and ventilation are in good working order.

Use oil coolers. They dry the air very well.

An air conditioner will help maintain normal levels in the room. It can either increase or decrease the humidity in the apartment.

Helps reduce humidity sunlight penetrating through the windows.

The humidity of the apartment must always be normal for normal existence. The health of loved ones and pets depends on this. What the humidity level of the apartment will be in order to live comfortably must be determined by its owner, but it is still worth adhering to the standards. Comfortable humidity will help not only a speedy recovery of children, but also a quick fall asleep, this is important for people with sleep disorders.

Indoor air temperature and humidity parameters:

During the cold season in living rooms, the optimal temperature is 20-22 degrees, and optimal humidity 30-45%. Similar figures are given in SNiP 2.04.05-91* “Heating, ventilation and air conditioning”, Appendix 5 as mandatory, cold (winter) and transitional (spring and autumn) periods - optimal humidity 30-45%. The same figures are given in SanPiN 2.1.2.1002-00 “Sanitary and epidemiological requirements for residential buildings and premises.”

The loss of condensation does not in any way indicate the quality of the window and is allowed by the State Construction Committee of Russia: “International standards (ISO, EN standards) also allow temporary formation of condensation on the inner glass of a double-glazed window.” (Letter of the State Construction Committee of Russia dated March 21, 2002 No. 9-28/200)

According to SNiP 2.04.05-91 “Heating, ventilation and air conditioning” for residential premises, the nominal outdoor air flow rate should be 3 m3/hour per 1 m2 of residential premises. (For example: According to GOST 30674-99 “Window blocks made of polyvinyl chloride profiles” maximum the air permeability of 1 m2 of window should not exceed 3 m3/hour. The area of ​​a double-hung window for a room of 15 m2 is approximately 1.8 m2. That is, the supply of fresh air through a high-quality window does not exceed 5.5 m3. Which is approximately 7 times lower than necessary...).

Good question: Is it necessary to humidify the indoor air?

In other words, for a normal indoor microclimate it is necessary to either ventilate the room or install additional ventilation systems.

Normal humidity in residential premises is defined in SanPiN 2.1.2.1002-00. "Requirements for residential buildings and premises." Normal humidity in a room where there is no compulsory system ventilation, maintained through regular airing.

In accordance with SNiP II-3-79* “Building Climatology”, the following room modes are distinguished based on the humidity level: dry (less than 40%), normal (40÷50%), wet (50÷60%) or wet (over 60 %). According to GOST 30494-96 “Residential and public buildings. Indoor microclimate parameters”, air humidity in residential premises is not allowed to exceed 60% (the optimal humidity value is no more than 45%).

New standards SNiP 23-02-03 "THERMAL PROTECTION OF BUILDINGS" have determined the design parameters of the relative humidity of premises to determine the dew point and temperature requirements for inner surface windows:

5.9 ... The relative humidity of internal air to determine the dew point temperature in places of heat-conducting inclusions of enclosing structures, in corners and window slopes, as well as skylights, should be taken:

- for premises of residential buildings, hospitals, dispensaries, outpatient clinics, maternity hospitals, boarding homes for the elderly and disabled, comprehensive children's schools, kindergartens, nurseries, kindergartens (plants) and orphanages - 55%, for kitchen premises - 60%, for bathrooms - 65%, for warm basements and underground areas with communications - 75%;

— for warm attics of residential buildings — 55%;

- for premises of public buildings (except for the above) - 50%.

5.10... The temperature of the inner surface of the structural elements of the glazing of windows of buildings (except for industrial ones) must be not lower than plus 3°C, and of opaque window elements - not lower than the dew point temperature at design temperature outside air during the cold season, for industrial buildings— not below zero °C.

This article provides data from SNiPs and GOSTs (quite “soft” compared to European standards) so that you can take the necessary actions to create a comfortable microclimate (from the point of view of standards) in your home.

The norm of air humidity in the apartment

Air humidity is a very important indicator that affects the microclimate of a home and a person’s well-being. What is the normal humidity level? How to determine it and what are the norms in different rooms? Read below!

The humidity indicator indicates the content of water vapor or the degree of saturation of the surrounding air with it. As a rule, in everyday life the indicator of relative humidity is used, which is determined by many devices (household hygrometer or MagicAir base station, which is included in breathers).

Standards according to GOST in residential premises

GOST 30494-96 regulates the following humidity standards, based on the time of year: 30-45% in the cold months, 30-60% should be in the warm months. The limit in an apartment in winter according to GOST should be no more than 60% and no more than 65% in the summer.

GOST indicators are standard values, but physiologists recommend listening to them and maintaining air humidity in the apartment in the range of 40-60% at any time of the year.

The lower figure is 30% and this is already dry air, uncomfortable for a person, causing dry eyes, overwork, fatigue, and decreased immunity. When the air in the room is dry, the leaves of indoor flowers begin to dry quickly, and there is a high probability of developing allergies in a person.

Standard for a children's room

The microclimate in the nursery is very important for the health and activity of the child, and maintaining comfortable humidity is one of its indicators.

Dry air in a children's room is strictly not recommended! And that's why. It acts more slowly on adults, children tolerate dryness more difficult, and their body begins to actively lose moisture. The nasopharynx dries out and, as a result, the body quickly “cages” various infections. The child experiences itching in the eyes, peeling of the skin, and is lethargic and inactive.

It is advisable to maintain the temperature in the children's room at 23-24 degrees all year round, since strong fluctuations are harmful to children. You should not overheat the room, because with the air humidity in the apartment at 60% and a temperature of 25-26 degrees, a feeling of the tropics will be created. And children tolerate heat worse than coolness. And for a middle-aged person it’s hard and tiring.

Standard for the workplace

A lot here depends on what industry a person works in. So, in pharmacies and pharmaceutical production the air will be drier than in greenhouses or in a restaurant kitchen. Typically not supported in offices high humidity, since it greatly affects the operation of office equipment and the safety of documents. 40-60% is exactly the normal air humidity for a person that should be maintained at home and in the office.

What to do if the humidity is higher or lower than normal

You can use a humidifier to increase the humidity level. This is an easy way to create a comfortable microclimate at home or in the office.

How to reduce air humidity?

We create normal air humidity in the apartment

Firstly, ventilate the room more often! Regularly arriving Fresh air can improve the microclimate and have a beneficial effect on humans. If you live near highways or industrial enterprises, you can organize ventilation even when closed windows. To do this, you will need to install a breather in the room - supply ventilation, which will regulate the humidity level and will ventilate even with the windows closed. You can choose the breather that suits you on our website mastervozduha.ru.

One of the reasons for high air humidity may be leaks in pipes, which are important to eliminate. If it is humid in the kitchen, installing a good hood above the stove will help reduce this indicator.

By maintaining optimal air humidity in the apartment, you can reduce the number of diseases in children and adults, increase their activity, performance, concentration and attention.

The level of humidity plays an important role in ensuring comfort in the apartment. Thus, high humidity promotes the development of potentially pathogenic organisms and mold, which can pollute the air with toxins. And low levels can cause irritation of the mucous membranes of the nose, throat and dry skin. What air humidity is considered normal in an apartment?

A relative humidity of 70% means that the air contains 70% of the water vapor it can absorb at that temperature. Thus, your comfort directly depends on the delicate balance between temperature and air humidity percentage.

At 60% relative humidity, moisture discomfort will be felt more at 30°C than at 20°C. This is because air at 30°C is saturated with moisture faster, that is, it can contain more water vapor than at a temperature of 20°C and the same humidity level. Therefore, a person will experience greater discomfort from humidity at 30°C. Conversely, a humid day will feel warmer than one with higher temperatures but drier air.

In general, relative humidity of 30 to 70% covers all recommended ranges. In a medical environment, normal humidity in an apartment is considered to be between 40 and 60%. Very low moisture content in indoor air can cause respiratory complications. Thus, relative humidity below 30% is too uncomfortable for living.

Permissible indoor moisture concentration in winter

Increased humidity in an apartment in the winter can cause increased heating costs, since it will be necessary to further heat the water contained in the form of moisture in the indoor air. Moisture creates a feeling of cold, which stimulates an excessive increase in air temperature. Too much humidity can also cause health problems, including respiratory problems in children and the elderly, who are most at risk.

When humidity levels are low, we will experience dry skin, chapped lips, irritated throat and nose, and difficulty breathing. In this regard, the recommended relative humidity to prevent the formation of condensation on windows in winter is from 30% to 50% with an average room temperature of 18 to 24°C:

• on colder days - 30%;
• on warm days - 50%.

During the summer months, the relative humidity level should be no more than 50% if the room temperature is constant between 22 and 25°C. Ideally, the humidity level in an apartment or house in summer should fluctuate around 45%. Anything below 30% is too dry air, above 50% is very humid.

As noted above, when humidity is low, you will feel the air colder. This occurs due to the evaporation of moisture from the surface of the skin, which provides a cooling effect.

How to quickly and easily measure humidity levels?

Condensation on the windows, things in the closets have become somehow damp, mold has appeared in the corners or on the walls of the house or apartment... Every time you pay attention to such changes in the house, this indicates that your living space has too much moisture .

To check whether the air in your home is too humid, you will need simple items that are found in every home. This test can be done in any room except the kitchen, since if you have just cooked the food, the results may not be as accurate:

1. Take a glass, put three ice cubes in it, fill it with water and stir.
2. After this, leave the glass on the table and wait for a total of three minutes, and then check if there is condensation on the outside of the glass.
3. If not, then the air in your home is too dry and you need to purchase a special humidifier.

A better and more accurate way to measure humidity is to use a special hygrometer. There are quite a few options for hygrometers on sale, located in different price ranges. Cheaper models are mechanical. They respond to changes in humidity more slowly than digital models. The most advanced of them are automatic; they detect air humidity and make recommendations for optimizing the operation of your air conditioner to avoid discomfort in the apartment.

What to do if the indicators are higher or lower than normal?

Here are the main reasons why we should maintain an optimal level of humidity in our home:

• the number of bacteria and viruses is significantly reduced;
• the risk of allergies caused by dust mites and other pathogenic organisms is reduced;
• we get rid of mold and mildew and reduce the content of toxins in the air;
• creating a more pleasant atmosphere;
• we reduce heating costs;
• we get rid of the threat of damage to the house and furniture;
• We care about the health of our children.

Please note that the optimal air humidity in an apartment for a child is in the range of 50-70% at an air temperature of 18-19°C.

If the air in your home is too dry, there are three standard way fix this problem:

1. Evaporation. Place a container of water on the surface or next to the radiator.
