Humidity in a room, in particular in an apartment, house or office, is the factor that affects the overall microclimate, as well as the air temperature. It is worth noting that it is categorically not desirable to forget about such an indicator, since it can cause excessive heat or vice versa cold, and if the norm is not maintained, then there is a high probability of a violation of the state of human health, plants and even interior items. What is a comfortable humidity for a person and what should it be normal in terms of indicators? These are the questions discussed below.
Humidity in the room: the norm and the consequences of its lack
The optimal humidity in a room is one that is at the right level.
The indicator influences how:
- It's nice to be in a living space;
- It is convenient to be there for people who have health problems;
- Healthy family members.
It is worth noting that too high and too low a percentage of moisture can be dangerous both for health and for the surrounding atmosphere. That is why you need to learn how to check the humidity level in order to maintain the most optimal performance and avoid problems. If a home humidity test reveals the fact that the level is too low, then this can cause increased loss of moisture from the human body through the skin and respiratory tract.
The consequences of such processes may be:
- Reduced hair elasticity.
- Decrease in the strength of the nail plate.
- Decreased elasticity of the skin, which is accompanied by the formation of microcracks, wrinkles and peeling.
- Drying of the mucous membrane in the eyes, which can cause itching, redness and a feeling of the presence of sand.
- Thickening of the blood fluid, which can cause a slowdown in its circulation and the formation of blood clots.
- Viscosity of gastric and intestinal juice, which significantly impairs digestion.
- Drying of the mucous membrane in the respiratory tract, which leads to a weakening of the immune system, as well as the frequent occurrence of SARS.
Insufficient humidity contributes to reduced resistance to the formation of an allergic reaction.
Normal humidity in the apartment and high
Some believe that the required humidity, even in winter, even in summer, should be exceptionally high, but in fact, excess moisture can cause the formation and spread of fungus and mold, as well as other pathogenic bacteria. These problems are far from the most pleasant and it is almost impossible to get rid of them, even if you use strong and expensive means.
The presence of mold and mildew leads to:
- Frequent respiratory diseases;
- Chronic runny nose;
- bronchitis;
- asthma;
- allergies;
- Feeling of dampness around;
- Unpleasant odors;
- Duhote;
- Deterioration of the general condition;
- dizziness;
- Increase the time it takes to wash bed linen.
If the relative humidity is too high, then this can negatively affect the condition of interior items, finishing materials, and even plants, as they begin to rot and die. Parquet, wooden coverings and similar elements begin to swell, crack and significantly lose their proper appearance. Too humid air in a child's bedroom is literally dangerous to health.
How to measure air humidity at home
What should be the level of humidity today is a very popular question. It is worth noting that you can measure the indicator in the bathroom and other rooms of the house quite independently. There is a special household moisture meter, which can be used to measure humidity without outside help. In another way, it is called a hygrometer, which is recognized as the ideal and most accurate way, not capable of giving an error.
Before measuring how much the humidity in the room is, you need to choose the type of hygrometer, as it happens:
- Electric;
- Chemical;
- Condensing;
- Hair and more.
To determine the humidity in the apartment, the measurement device can be used the most simple, in which the error is only 3%. As a rule, the device is combined with a clock and a thermometer. The measuring device should be placed as far as possible from the source of moisture and heat, and in order to interpret the data that the indicator shows, you need to use the standards that the Assmann table contains.
There is an easier option to measure the level of humidity and for this you need a moisture meter in the form of an ordinary glass of water.
Water is poured into the container, cooled to - 3 - 5 ° C, after which it is placed on the surface of the table, but as far as possible from the batteries. It is enough to observe for 10 minutes and condensation will begin to accumulate on the walls, which is the result of a temperature drop. If, after the formation of condensate, the glass dries as quickly as possible, then the humidity is very low, and if it remains misted, then the microclimate is normal. There is another option, when trickles of water begin to flow, which indicates the presence of high humidity.
What humidity should be in the room
It is believed that the average temperature in the room should vary between 20-22 ° C, however, from this indicator, if it is unstable, the humidity may be too low or too high. There are many factors that can affect changes in humidity and, first of all, this is air temperature. Accordingly, the warmer it is, the more water vapor will be dried and vice versa.
Relative humidity is estimated according to the rule - the warmer the air, the lower its relative humidity, even if it contains the same amount of water vapor.
To carry out the process of maintaining optimal humidity, you need:
- Carry out regular ventilation;
- Maintain a warm temperature;
- Remember that if it is low, then you need to increase it a little, which can be done by hanging wet clothes, installing an aquarium, heating a pot of water without a lid, and installing plants that can maintain an optimal microclimate.
Dry the air: furniture, Decoration Materials, heating appliances, carpets, air conditioning and more.
Permissible indicators: normal air humidity
Favorable humidity is the correct selection of interior items, as well as maintaining an optimal microclimate in the room. To determine the humidity, you need to use a special meter, but to increase the indicator, provided that it is low, or vice versa, you need to reduce it, pay attention to the standards. It is worth noting that they directly depend on the season and where exactly the measurement is taken.
For residential premises:
- In summer, humidity is 30-60%, but the maximum allowable level for regions with a subtropical climate is 75%, and in cold weather 30-45%, but 60% is acceptable.
- In the auxiliary room in the form of a bath, a toilet, a corridor and a pantry, there is no specific indicator of humidity.
- In which a lot of upholstered furniture is installed and there are antiques, the temperature should be maintained at 60%.
- In which there is an emphasis on the situation with equipment, it is desirable to maintain a humidity of 40%.
- Where are the books on open shelves humidity should be no more than 36%.
In places where there is a large number of plants, 80-95% is enough, but on condition that they are suitable for a subtropical climate.
Comfortable indoor air humidity for a person
Permissible humidity in the apartment or wooden house on average should be no less than 30-40% and no more than 65%. Now there are many ways to maintain this level, but you need to take into account the fact that humidity is the ratio of warm and cold air flows. If the humidity deviates from the norm, then there is a sharp difference between them in volume.
Adjustment of such an indicator as the room humidity level can be carried out independently and without special investments, and to lower it, you need to carry out:
- Regular ventilation;
- Installation of an exhaust fan;
- Use of a special dehumidifier or climate system;
- Timely repair water pipes to avoid leaks;
- Use heating devices;
- Installation of hoods in the kitchen and in the bathroom.
With regards to increasing humidity, it is enough: to install an aquarium, purchase decorative fountain, use the air conditioner and heater to a minimum, hang wet towels, periodically spray the room with a spray bottle, or install special humidifier air. Each room has its own optimal level of humidity and therefore it differs significantly, for example, in treatment room or in the children's room.
Device for measuring the humidity of the air in the room
The device that determines and shows the level of humidity is called a hygrometer, as already mentioned to the wound. The principle of operation of the device is very simple, as it allows you to measure the humidity in the whole room and through the study of each individual piece of furniture. A prime example can become an ordinary hair hygrometer, which requires degreased human hair for diagnosis.
The most ordinary simple human hair can show what is the humidity in the air, since if:
- It is overdried, then, accordingly, it is reduced;
- He is too fat, then elevated.
An apparatus called a film-type hygrometer is no less in demand, which is the most sensitive relative to the level of humidity, and an organic film is used to study the indicator.
There are other types of hygrometers, but at home it is not only undesirable to use them, but it will not work either, since they are directly related to industry.
There are a number of devices for measuring humidity and they are called psychrometers, which are in great demand in everyday life.
It is worth noting that a hygrometer can give an error of 5% when detecting an indicator, but a psychrometer is the most accurate equipment that cannot lie. The simplest psychrometer has two sensors - dry and wet. The principle of operation is impossibly simple, because if the humidity is high, then the sensor is set to moisture, and if it is low, then to dryness.
Normal air humidity (video)
Humidity can be dangerous both at low and too high levels, and therefore it is important to monitor indicators and take certain measures in a timely manner. With the formation of tenacious mold, it will be correct to reduce humidity.
The norm of humidity in the apartment - important condition comfortable living. Few of us think about it, however, this indicator is no less important than lighting and noise levels. Not only the condition of the premises, but also furniture, household appliances, and most importantly, the health of the residents themselves depend on its observance.
The negative side of increased dryness
So, what affects the rate of humidity in the apartment? First of all, it is its decrease, or rather dry air, that is dangerous. It provokes the accumulation of a large amount of dust, and, therefore, the following health troubles:
Negative aspects of high humidity
It should be noted that high humidity is also very dangerous. Often it leads to the development of asthma, allergies or a runny nose. However, such conditions are extremely rare in city apartments, the main problem was and remains central heating, which shamelessly dries the air. In addition to it, working companies can also influence this indicator. Appliances, processes in which a person participates (cooking, ironing, washing, etc.). They play a significant role weather and, of course, the time of year.
It should also be noted that if the norm of humidity in the apartment is exceeded, this can adversely affect the condition of the surfaces of the walls and ceiling. A significant excess of moisture in the air over a long period of time provokes the formation of fungus and mold on the walls. When their spores enter the human body, infection and backfire guaranteed. 
Existing regulations
What is the humidity level in the apartment? To answer this question, it is necessary to take into account the purpose of the room. So, experts call acceptable indicators that fit into the following ranges:
- Non-residential premises (dining room or living room) - from 40 to 60 percent;
- Bedroom (for living adults) - from 40 to 50 percent;
- Bedroom (for living children) - from 45 to 60 percent;
- Non-residential premises (office, dark rooms) – 30–40 percent;
- Kitchen - 0t 40 to 60 percent.
The permissible norm of humidity in an apartment for a person, animal or thing is significantly different. For example, Appliances, books, wooden furniture are better preserved at a humidity level of 45 to 55 percent, and houseplants- from 60 to 70. Based on this information, we can conclude that the state of the air is extremely important not only for a person, but also for the surrounding living beings, and even objects. 
The figures are the same for every season. So, the norm of humidity in an apartment in winter should be in the range from 50 to 60 percent, similar figures are relevant for summer and off-season.
Determine the state of the air
How is the humidity in the apartment determined (norm or deviation)? For this purpose, a special device has been developed, which is called a hygrometer. Externally, such a device can be performed in several variations (for example, an electronic scoreboard or a clock). Install it in the back of the room, where there are no drafts and distractions. external factors. This is done in order to reduce possible errors to a minimum.
Folk methods
There are a few more simple, but enough effective methods, which determines the humidity in the apartment. The norm or discrepancy to it can be calculated even with the help of an ordinary glass of water. So, a chilled glass container is placed in the center of the room and the evaporation of condensate is observed. If dryness was achieved in less than 10 minutes, you need to take urgent measures to humidify the air, if in the same period of time the condensate has turned into large drops, then the situation can be characterized as the exact opposite. 
Improving the current situation
How can the norm of humidity in the apartment be achieved if special devices are not used? There are several simple ways, which you can also take into service to combat increased dryness:
- Airing. Regularly open the window (not the window) at any time of the year for 5-10 minutes.
- Diversify the flora in the room, plant more green plants.
- In the absence of contraindications (asthma), purchase an aquarium.
- Don't forget to carry out wet cleaning, preferably at least 1-2 times a day;
- To neutralize the heat from the battery, water containers installed near the heaters will help.
The norm of humidity in the apartment in winter is very problematic. Often the simplest measures are not enough for this, because the frosty air contains a minimum of moisture. 
Special funds
How can you raise the level of humidity in the apartment, the rate of which was previously considered almost unattainable? The easiest way out of the situation can be a special device - a humidifier. To date, there are several types of them for sale:
Modern devices allow not only to achieve the required indicators, but also to maintain them at the proper level. Such properties allow you to protect the health of residents and ensure the safety of furniture and things in the apartment.
Each device has a certain radius of action (suitable for the footage of the room), which, as a rule, is indicated on the product packaging or in the attached instructions.
Air humidity not only affects the furniture, floor and other elements of the room, but also the health of residents. Not only the state of comfort in the house depends on humidity, but also the appearance of various kinds of diseases.
Allergic rhinitis, bronchial asthma, acute rhinitis - all this can be the consequences of excess moisture content in the air. Dry air flow also does not have a positive effect, as a result of its influence, sinusitis may appear, and sinusitis “likes” such an atmosphere.
What should be the humidity in the room? Normal indoor humidity is the key to good health.
Due to the lack of moisture, the immune system worsens, fatigue increases, “sand” is felt inside the eyes, and the skin begins to age rapidly. Children do not tolerate constant changes in humidity, and for newborns this is a serious danger.
The mucous membranes of the respiratory tract in children, becoming dry, can contribute to the development of infections, an allergic reaction. The child may have a runny nose along with blood. Once it occurs, treatment may not be effective.
Factors Affecting Humidity
Weather and climate, the season, the functioning of household appliances, human activity - these are the factors that affect the humidity in the air.
The situation becomes critical when the heating season comes. Frosty air contains small amount moisture. One airing inside the apartment will not help to eliminate this problem.
Central heating and the operation of heaters in general can worsen the situation.
Moisture levels can drop by up to 25% due to desiccation. The mucous membrane of the nasopharynx of an adult takes this indicator as 35%. The child seems to be 50%. During summer period inside the machine, the air becomes dry due to the operation of the air conditioner.
What should be the rate of moisture in the air?
What humidity should be in the room? This question is very important. Comfortable humidity in the room for a person is different. According to most opinions, the humidity standard is 45%.
But moisture should vary in the region of 30-60%, and it depends on the room, or rather on its purpose:
- Inside the dining room, this figure should be 50-60%.
- Average in adult bedroom – 45%.
- Inside the children's room - 50-55%.
- The percentage inside the cabinet is 40.
- The average level in the kitchen or bathroom is 50%.
It is very difficult to maintain such a state of moisture in the room. AT modern apartments and houses most year, the level of air moisture is quite low. Because of this, a living person in such a room can cause drowsiness, and performance decreases.
Dry airflow can cause the body to cool down as it evaporates from the skin. The skin, in turn, cools the human body.
In the dry air stream, static electricity accumulates and dust easily rises.
Achievement optimal level moisture is a mandatory procedure in the room where the children are. Therefore, it is imperative to purchase an additional humidifier.
To achieve the norm of moisture, it is necessary to control it, as well as take all necessary measures.
Air humidification methods and control
We have already considered the necessary indicators. In order not to deviate from them, you need to use methods that will help maintain balance. Let's consider these methods in more detail.
Heating during the winter season can dry out the air, causing indoor discomfort. It can also spoil wooden crafts, cracks may appear in them.
To improve the quality of moisture content, it is necessary to install a humidifier where you are. the largest number time. During the summer period, depending on the climate in your area, the moisture content may be low and vice versa.
The following measures need to be taken:
- It is important to constantly ventilate the room. It's easy enough to do, but high efficiency due to this is not achieved. During the summer period, there is not much moisture in the air, so ventilation is not the way to go. And in winter time ten minutes of airing is enough to achieve the necessary moisture. The windows should preferably be wide, since in this short period of time the air will be able to renew itself. An open window clock will not have this effect.
- Increasing the number of indoor plants. They are not only "humidifiers" of the room, but also help to determine the level of humidity. If the plant is shriveled and has dried leaves, then the air in the room is too dry. In addition to moisture, plants can produce substances of organic origin that clean and disinfect the surrounding space.
- Aquarium. It would seem that the aquarium is considered ordinary decorative element, but its impact on maintaining moisture levels is invaluable. It is only necessary to constantly add water, which evaporates.
- Wet cleaning. It can be done in the morning or evening.
- Finding indoor water containers. They are recommended to be placed on window sills where central heating radiators are located.
To increase moisture, a number of procedures can be carried out. One of these procedures is in the apartment. Or gender. Or even waterproofing an apartment in a new building.
Evaporating water is a great way to humidify the airflow. But this is not entirely hygienic and aesthetically pleasing.
What needs to be done in order to independently find out the level of humidity in the room? To do this, it is important to control the microclimate and the level of moisture.
What is used to measure the humidity in the air at home? For this, it is used, which is called a hygrometer.
On the this moment there is different kinds this device, which have a different principle of operation. They can be small size. The scoreboard can be mechanical or electronic. The device may additionally have a thermometer.
The main thing for a hygrometer is the accuracy of its readings. The maximum error is 1%. But modern electronic devices give almost the most accurate readings.
These devices should be installed where there are no drafts.
If you do not have this device, then to measure the level of moisture, you will need an ordinary glass of glass and water. So you just need to type cold water into the inside of a glass beaker, after which it must be put in the refrigerator. The water temperature should reach 4-5 degrees Celsius.
The glass must be located where there are no heating sources.
Watch:
- if the condensate dries in about ten minutes or less, the air is very dry;
- if after the same period of time the condensate becomes large drops, and they begin to drain, then this means an excess of moisture;
- normal humidity in the room when the condensate after the same ten minutes did not have time to dry and did not begin to drain.
A glass glass and water is an excellent “hygrometer”, only made by yourself with your own hands. This method will help determine the humidity in the room.
The meter can be used with an ordinary mercury thermometer. But the measurement process is quite laborious.
It can be divided into two stages:
- First, the temperature is measured and recorded.
- Next, the thermometer head is wrapped with wet cotton wool. It should be left for ten minutes. Then the temperature must be measured again.
To determine the "dry" or "wet" temperature, you must use a specially designed temperature.
Therefore, it is best to purchase a modern electronic hygrometer, which will give the most accurate readings.
So, in order to control the humidity of the air inside the room, it is important to set goals. Such goals are: creating a comfortable atmosphere, preventing the development of diseases and infections, ensuring safety, and waterproofing.
Control can be carried out using improvised means, or you can use a specially designed device. It will help you cope with the problem, ensuring maximum comfort indoors.
The article discusses in detail such a concept as air humidity in an apartment: the norm of this indicator for residential premises for various purposes, prescribed by GOST, the consequences for a person resulting from deviations from the norm in one direction or another. The text describes alternative ways measurements of moisture levels and intended for this, as well as recommendations for maintaining optimal climatic conditions.
Humidity in the apartment: normalwater content for comfortable living conditions
The optimal level of air humidity is one of the components that provide comfortable climatic conditions for human habitation. Moreover, each of the rooms, depending on its purpose, has its own microclimate. Most often, people care about the temperature and quality of the air masses in the house, forgetting about this indicator. But it is the number of water (steam) molecules in the composition of air that affects the perception of temperature by the human body, the safety of the situation in the room and the condition of plants.
Note! The generally accepted average of normal air humidity in an apartment should be at the level of 45%. It may vary depending on the type of premises and its operating conditions.
Deviation from the norm is possible, both in the winter season and in the warm period. In both cases, a lack or excess of moisture leads to a deterioration in human health, the condition of plants and damage to furniture, finishes, etc.
What should be the humidity in the apartment (average indicators for the main premises):
| Room type | Humidity level, % |
| Canteen | 40-60 |
| Bathroom, kitchen | 40-60 |
| Library and work area | 30-40 |
| Bedroom | 40-50 |
| Children's | 45-60 |
Rooms such as the kitchen, bathroom and toilet will always have elevated level moisture, so the standard for these rooms is higher than for other rooms.
What are the consequences of a deviationfrom humidity standards in the apartment: dry air
When the batteries turn on, the air in the rooms becomes dry. As a result, the residents irritate the mucous membrane of the throat and nasal cavity. Drying of hair and skin is observed. If the humidity norm is violated in a residential area, static electricity is generated, which raises dust particles into the air. This process can be the basis for the spread of germs and dust mites.
Excessive dryness of the room entails many negative consequences:
- decrease in the elasticity of the skin, nails and hair - as a result of this, dermatitis, peeling, microcracks and premature wrinkles appear;
- drying of the mucous membrane of the eyes - redness, unpleasant itching and sensation of foreign bodies ("sand");
- blood thickens - because of this, the circulation of blood flow slows down, a person develops weakness, headaches. There is a decrease in efficiency, the heart is subjected to increased stress and wears out faster;
- the viscosity of intestinal and gastric juice increases - the work of the digestive system slows down significantly;
- dryness of the respiratory tract - as a result, local immunity is weakened, the likelihood of colds and infectious diseases increases;
- air quality decreases - a large amount of allergens are concentrated in the composition of air masses, which, at the norm of indoor air humidity, are bound by water particles.
Note! Plants and animals that are close to the apartment suffer from a lack of moisture. Reduced service life wooden furniture and finishes, they fade, become covered with cracks.
What are the consequences of exceeding the norm of humidity in the room
An excess of water can also be dangerous for humans, so many people wonder what air humidity is considered normal in an apartment and how to keep climatic conditions within this indicator. Increased content water vapor in the room becomes an excellent breeding ground for fungi, mold and harmful bacteria.
In such conditions, many problems arise:
- The frequency and severity of respiratory diseases increase - diseases such as bronchitis, runny nose, allergies and asthma become chronic, difficult to treat.
- The microclimate in the rooms becomes unacceptable for life - people feel damp or stuffy in the rooms.
- The feeling of freshness is lost - the excretions of multiplying pathogenic organisms cause the appearance of unpleasant odors.
- Increases the drying time of washed laundry.
An increased indicator of air humidity in the apartment is also harmful to the situation. Plants begin to rot, mold appears on the ceiling and walls, wooden surfaces undergo deformation. Books and other paper products change structure.
What should be the humidity in the apartment: standards according to GOST
Humidity can be relative or absolute. To create comfortable climatic conditions in the house, it is calculated optimal value. GOST 30494-95 regulates an indicator indicating what normal air humidity in an apartment should be.
Relative humidity is indicated as a percentage in the form of two values:
- optimal indicator;
- permissible value.
The permissible value is the limit that does not harm human health, but can adversely affect overall well-being, mood and reduce performance.
Note! If in relation to bedrooms, children's rooms and other areas where a person stays for a long time, certain rules, then it is not necessary to strictly adhere to normal humidity in the kitchen, bathroom, corridor and bathroom. These rooms are considered auxiliary.
The actual vapor content in 1 m³ of air is taken as the unit of measure for absolute humidity. For example, one cubic meter of air can contain 13 g of water. In this case, the absolute humidity will be 13 g/m³.
To obtain relative humidity, you will need to perform certain calculations. This requires two metrics:
- the maximum possible water content in 1 m³ of air;
- the actual amount of water in 1 m³ of air.
The percentage of real data to the maximum possible indicator will be the relative humidity. For example, 21.8 g of liquid can fit in 1 m³ of air at a temperature of 24°C. If in fact 13 g of water is present in it, then the relative humidity will be 60%. For convenience, you can use a special table of absolute humidity, which contains auxiliary data.
Indices of the norm of humidity in the room according to GOST
The indicator prescribed by GOST depends not only on the purpose of the premises, but also on the season. For the warm period, 30-60% is provided. In this case, the indicator of relative humidity in the room is 60 percent, and the maximum allowable will be 65%. For some regions, where the summer months are accompanied by high humidity, the standard value can be increased to 75%.
For the cold season, the standards for relative humidity in the room are 40-45%. In this case, the maximum allowable value is 60%.
The most popular manufacturers and best models, Comparative characteristics structures, their advantages and disadvantages.
The norm of air humidity in the apartment for a child
The child's immunity is not so effective in coping with the negative influence of factors environment like an adult body. Children overheat or freeze much faster, catch colds easily, suffer from infectious diseases and are more difficult to tolerate.
For this reason, it is important to maintain optimal air humidity in an apartment for a child, especially in his room, where it is necessary to create conditions for maintaining the immune forces of the baby.
In no case should the air in the children's room be dry. Such an atmosphere provokes an intense loss of moisture in the baby's body. Drying of the mucous membranes of the nasopharynx leads to their inability to resist viruses and infections. The child may develop itching in the eyes and peeling on the skin. For a child, it is considered optimal air humidity in the apartment in the range of 50-60%.
According to Dr. Evgeny Komarovsky, the value of normal air humidity in an apartment can be increased to 60% for a healthy baby and 70% for a sick child. infectious disease. The higher the level of humidity, the less intense the drying of the mucous membranes.
Indicators of normal humidity in an apartment for a child's body in winter are the same as for the warm season. However, there is one caveat here: the maximum air temperature in the room should not exceed 24 ° C. If the room is hotter, then the humidity of 60% will make it tropics. In practice, in the heat, increased humidity in the apartment is more difficult to endure than in the cold season.
Important! Exceeding 24°C in the children's room can lead to overheating of the baby's body. As a result, the drying of the mucous membranes and the loss of fluid will accelerate.
How to achieve optimal humidity in the apartment
The main factor providing greatest influence on humidity, is temperature. The warmer the room, the more water able to absorb air. However, when calculating relative humidity, it is worth remembering that at high temperatures the volume of liquid in the same amount of air will be less. This nuance can be advantageously used to maintain the norm of humidity, the air outside in winter is very fresh and optimal parameters are provided by ventilation.
Humidity is absorbed:
- devices intended for heating;
- interior items such as toys, cushioned furniture, carpets;
- air conditioners.
Plants and an aquarium, containers filled with water, wet laundry, a leaky roof or pipes can be considered as a small source of moisture.
How to determine the humidity in the apartment without device
To determine how strongly the level of humidity in the house has deviated, you can do without a special device and use:
- a glass of water;
- Assman table;
- fir cone.
To determine the relative humidity of the air with a glass of water, it is necessary to cool the filled container in the refrigerator to 5 ° C. It will take about 3 hours for the water and vessel to reach the specified temperature. After that, the glass is placed away from the battery on the table. Condensation will form on the walls of the container within 5 minutes.
Further results will depend on the behavior of this condensate:
- After a few minutes, the glass dried out - the moisture index was lowered.
- Condensation on the walls has not disappeared - the room has a normal microclimate.
- Drops flowed down the vessel in streams - there is an excess of moisture in the air.
A spruce cone can serve as a measuring device. It should be put away from heating appliances and after a few hours check the condition of the scales. If the air is too dry, the cone will open, if there is an excess of moisture, the scales will shrink tightly.
All of these devices only indirectly indicate the presence of a problem. To accurately determine the microclimate in the room, it is better to buy an air humidity sensor.
Useful advice! Dry plant tips are the primary sign of dry air. Insufficient levels of moisture can also be identified by synthetic clothing, which emits electrical charges under such conditions.
Features of the use of the temperature and humidity sensor
To measure humidity, you can use special devices called sensors or hygrometers. The device independently converts the received data and displays the result as a percentage.
Many people are looking for a solution, wondering how to remove humidity in an apartment. To control the microclimate in the bathroom and in other rooms with an excess of moisture, exhaust fans. They prevent the formation of condensate on the walls and on the floor.
For residential premises, it is recommended to purchase a humidifier if there is a lack of moisture on an ongoing basis. You will also need to additionally buy air humidity sensors for the fan and humidifier, if they are not provided for by the designs of the devices themselves.
The operation of a hygrostat or sensor is based on the principle of operation of a thermostat. The device opens and closes contacts in response to the amount of water vapor in the air. Thus, the operation of the fan or humidifier becomes automated. The device turns on only when it is needed.
Humidity control in the apartment: how to reduce / increase the amount of steam in the air
Used to control the amount of vapor in the air various methods, including hand tools. Their combination allows you to achieve a certain result.
How to get rid of humidity in the apartment:
- Ventilate rooms regularly.
- Install exhaust fans where needed.
- Purchase an air conditioning system or.
- Timely make repairs in the house (maintenance of plumbing and plumbing).
- Use heaters and air conditioners.
- Avoid drying laundry indoors.
- Install a powerful range hood in the kitchen.
Useful advice! In order for the hygrometer readings to be reliable, it is recommended to install this device deep in the room in order to exclude the influence of drafts and other factors. orov.
How to increase the humidity in the room:
- Buy a table fountain or aquarium (if no one in the household has asthma).
- Minimize the use of air conditioning and heaters.
- Hang wet towels on radiators.
- From time to time, spray water with a spray bottle, thereby saturating the air with moisture.
- Regularly do wet cleaning in the house.
- Plant as many indoor plants as possible.
There are many devices that will allow you to achieve one or another result, depending on the needs. They are selected taking into account the microclimate in the house. Before buying them, it is recommended to accurately set the humidity parameters. To do this, measurements are taken over several days.
Perfectly fit into the interior
To maintain optimal humidity in the house, you can use special devices - humidifiers. This category of climate technology includes many modifications: traditional, steam, ultrasonic devices. Air washers and climatic complexes are more complex versions of these devices, equipped with a hygrometer, timer and other useful additions. Helps fight mold UV lamp.
"The most important thing is the weather in the house," the famous singer sang. But it really is. An optimal microclimate will protect you from many diseases, while a violation of the balance of temperature and humidity is fraught with consequences.
But if everything is more or less clear with temperature, almost every house has a wall thermometer that records its changes, then what should be the normal humidity in the room (norm and tolerances), as well as how to measure it, not everyone knows. Today we want to pay attention to this issue so that each of you has perfect weather in the house.
What to aim for
Indeed, what should be the humidity in the room? The norm is an established corridor, which may be slightly higher or lower, but too much discrepancy threatens to worsen your well-being. Nowadays, they finally began to pay attention to this important indicator, put taps on battery radiators, and also buy special devices that help normalize the microclimate. The reason is clear, people react badly to changes in the microclimate and seek to neutralize this factor. What should be guided by, speaking about the humidity of the air in the room? The norm is about 45%, and this indicator should be strived for. 
Let's define terminology
There are several concepts that are directly related to the topic of our article. This is the relative and absolute humidity of the air in the room. Norm in this case is a measure of the presence of water vapor in the air. This is a fundamental characteristic of a healthy microclimate. That is, while we are talking about the absolute value. However, we are more interested in the relative humidity of the air. What does it mean? This is the ratio of the amount of water vapor in the air to the maximum possible amount at a given temperature. Now it’s a little clear what we mean when we talk about indoor air humidity. The norm varies greatly depending on what functional load lies on a given room. 
Regulated parameter
We are practically not interested in absolute humidity. Always, speaking about normal living conditions, we mean the ratio of temperature and humidity. Any person working in the health or safety industry will tell you that indoor relative humidity is a value that will not be the same for different buildings and rooms. In particular, six categories of premises are distinguished, depending on their purpose and features of operation. It should be noted that relative humidity is usually divided into optimal and permissible.
The standards we operate with
For the most part, we are interested in the humidity of the air in a residential area. The norm in this case is 45%. Although this figure is not the optimal indicator, but such a ratio of humidity does not threaten with complications for your health. Let's talk a little more about norms and standards.
So, depending on the saturation with water vapor, the air in the room can be dry, up to 55%. Moderately dry air is considered to be air with a relative humidity of 56% to 70%. At a percentage of 71% to 85%, the air is considered moderately humid. Finally, over 86% is very humid air.
So, in an office or residential area, it is necessary to maintain humidity from 45% to 50%. This is at least enough to not experience discomfort. These are the lowest values, the air humidity should be higher in industrial premises. The norm here differs depending on the specifics of production.
Take, for example, the tobacco industry. To store tobacco, it is necessary to maintain indicators from 65% to 80%, and if we take the production of cigarettes, then it is desirable to reduce air humidity to 55%. The printing industry is also sensitive to these indicators. For printing shops and paper warehouses, the optimal rate is from 50% to 60%. If we take woodworking shops, then the figures will be even lower, no more than 55%. Approximately the same figures must be maintained in the shops engaged in the textile industry. For a bakery, a room with a higher temperature - about 40 degrees, as well as a humidity of about 75% - is suitable. But greenhouses, which are created for growing tulips and mushrooms, require these figures to be raised to 95%. 
The consequences of deviating from the norm
In fact, it was not in vain that we decided today to talk about indoor air humidity. The SNIP norm was developed not just like that, but in order to protect human health as much as possible. Doctors know that this indicator is very important. Any deviation from the norm will affect your health. If the air is very dry, this causes increased evaporation of moisture from the skin, plants and furniture. As a result, the skin becomes dry, the signs of aging appear much earlier, and the hair becomes brittle and dull. As the skin ages rapidly and loses its elasticity, metabolism is disrupted. Dry nasal mucosa is the cause of frequent acute respiratory infections and runny noses. Therefore, if you notice one or more symptoms in yourself, then be sure to take care to increase the humidity in the room where you spend a lot of time. 
High room humidity
Setting the standards for indoor air humidity, SANPIN also notes the inadmissibility of too high values. First of all, it is fraught with the fact that humid environment promotes the growth of mold fungi and pathogens that cause various diseases. At high temperature air high humidity promotes overheating of the body, and at low temperatures - hypothermia. Although if we consider the premises with central heating, then it is better to over-moisten than over-dry.
Our home is our castle
We spend a lot of time at home, so it is very important that ideal conditions for life. Do not forget that SANPIN prescribes indoor air humidity standards relative to the room temperature. As we have said, relative humidity should be between 40% and 60% at an air temperature of 22-24 degrees.
If condensate begins to fall out and collect in drops, it means that the maximum allowable humidity has been reached. Usually we can observe such a phenomenon at the border of the heating seasons. The included radiators, electric stoves and air conditioners dry the air very much, and in the high season the humidity in apartments is usually lower than in the Sahara desert. Houseplants are the first to feel the dryness of the air. They begin to dry and fall off the leaves. Then all households, and especially small children, begin to notice its effect on themselves. 
Baby at home
With the advent of crumbs, parents immediately add anxiety. The heat exchange of the baby is still so imperfect that any airing is perceived by young mothers with hostility. In fact, in vain, because fresh air and compliance with normal temperature conditions are a guarantee normal functioning immune system.
The optimal temperature in the nursery is considered to be from +20 to +22 degrees (indicators from +18 to +24 are acceptable). To control it, a regular room thermometer is suitable. It is under such conditions that a balance is maintained between heat production and its loss. In this case, indoor air humidity also plays an important role. The norm for a child is from 50% to 70%. You can regulate it with the help of a special device - a hygrometer. 
What is fraught with dry air for the baby
Today, most of us live in apartments with central heating, so the problem of high humidity does not concern almost any of us. But its excessive dryness affects the child in a far from good way. Especially for newborns.
Exhaled air has body temperature and 100% humidity. And if the air in the apartment is dry, the body spends a lot of fluid to moisturize it. This loss of fluid leads to anxiety of the child, he sleeps poorly, is naughty, he often has a stuffy nose and difficulty breathing. Due to the drying of the mucous membranes, their protection against pathogenic bacteria and viruses worsens.
Requirements for the premises in which the pharmacy is located
We often go to pharmacies, because, unfortunately, medicines are an integral part of our lives. Pharmacies belong to the healthcare system, that is, the requirements for them are very strict. Medicines must be stored and sold strictly in the prescribed temperature conditions, the necessary lighting, humidity and other indicators that must be observed are also clearly spelled out.
The air temperature, which must be maintained by pharmacy staff, is from +18 to +20 degrees, not higher. It is under such conditions that most medicines are stored, except for those that should be in the refrigerator. What should be the relative humidity in the room? The norm in the pharmacy should not go beyond 40-60%. 
How to maintain normal performance
Humidity and room temperature must be constantly monitored. But everything is clear with the temperature - you need to hang a thermometer and observe its performance. With an excessive increase in it, you can reduce the heat supply or increase ventilation. If the temperature is below normal, then on the contrary, it is worth connecting an additional heat source.
Humidity is more difficult to measure, often we do not have hygrometers at home. Therefore, there are two ways to get out of the situation. The first - we manage with improvised methods. We install an aquarium in the room, hang the batteries with wet towels, and put cans of water next to the radiators. This will provide additional air humidification, but it is difficult to control.
If you want to be sure that the conditions in the room are optimal, then use special devices for humidifying the air. They are silent and safe. This is usually a water tank that is equipped with a micro-spray system and a small fan that blows dry air through the cloud. Some models are equipped with a hygrometer, others - with a hygrostat, which maintains a predetermined level of humidity in the room. But usually these are expensive models that are used in production.
The rate of relative humidity in the room is an important indicator that must be monitored.
