Knowing what the normal humidity is for a person indoors, you can create a comfortable environment for everyday life. Our country is mainly located in climatic zones, forcing most of the year to dwell with the heating devices turned on, and this makes the issue of maintaining an adequate level of humidification of air around even more urgent. How and by what means can indicators be adjusted to achieve the norm?
general information
Knowing what the normal temperature and humidity in the room are, being able to maintain the parameters as stable and adequate as possible, you can increase the quality of life and make your daily life comfortable. Methods of maintaining a pleasant climate allow a person to stay healthy longer, because excessively dry air provokes many health problems, deprives a person of beauty and youth. The microclimate of the living room is an extremely important aspect for human health at any age. However, too important air will lead to no less problems, so you should not go beyond.
What is unpleasant?
Humidity is a parameter that reflects how much air is saturated with water vapor. The absolute and relative parameters are distinguished. The first shows how much fluid is in a cubic meter of atmosphere, the second reflects the ratio of the parameters of the current indicator and the maximum possible. In practice, they almost always use a relative indicator. If the value is too low, gradually the person living in such conditions worsens the quality of the hair, the nails become brittle, the skin loses its elasticity. Due to the dry air, the mucous membranes dry too much, the blood moves more slowly inside the body, the person feels weak. Living in conditions of excessive dryness is accompanied by an increased risk of infectious diseases, as a person becomes more susceptible to them.
Maintaining normal humidity in the room according to GOST, a person undertakes to control the indicator, which should not exceed the maximum permissible limit. If the environment is waterlogged, the reproduction rate of fungal spores increases, and mold grows more actively. The danger of respiratory illness is becoming greater. The room smells bad, and the smell soon eats up in the interior, used in everyday things, and getting rid of it is very difficult. If too important indoor air persists for too long, the furniture begins to deteriorate.
About the norm
About what is the normal humidity in residential buildings, many know. This is told by various directories on the construction and arrangement of residential premises, norms and rules, standards stipulated by federal laws and regulations on the design of premises for a permanent stay of a person. To assess how close the current indicators are to normal, you should get a hygrometer. This is a fairly simple and affordable device that shows adequate values at the moment. Comparing them with the norms, you need to remember that different parameters are defined for different seasons and the level of air heating.
In the warm season, according to experts, it is advisable to keep the air in the apartment humidified to a level of 30-65%. If a person lives in an area with humid outside air, indoors, the normal rate rises to 75%. In cold weather, 50-55% is considered the norm, and 65% is considered the maximum possible reasonable limit.
Some rooms in human housing are distinguished by the peculiarity of the composition of the atmosphere. This is a bathroom, toilet, kitchen. Due to the peculiarities of operation of this territory, it is not possible to normalize the level of humidity.
Figures and rooms
In general, the recommended normal relative air humidity in a room used as a living room is 40-60% at an optimum temperature of 19-23 degrees Celsius.
For the bedroom, the optimum temperature is 16-19 degrees. A suitable level of humidification is 50-70%.
In the bathroom, humidity should be maintained within the range of 50-70%, while the optimal level of air heating is 20-23 degrees. Similar indicators of the humidity of the environment are characteristic of the kitchen, but here the temperature should be slightly less - about 18-20 degrees.
Certain standards are developed for stairwells of multi-storey buildings. Such are heated without this system. In the first case, the temperature normally varies around 17 degrees, the second option - within 10-15 degrees. The moisture level optimal for such areas is estimated at 50% and 60%, respectively.
About Verification
There are different methods for measuring normal indoor air humidity. The simplest option is a small device that you can buy in almost any hardware store. The hygrometer is designed to check the saturation of the atmosphere with moisture. On the display you can see a figure reflecting what is the air quality in the territory close to the subject.
Experts advise not to increase the degree of humidity in the summer. In the cold season, when people use heating devices, heating systems, different ways to correct the humidity level should be considered.
And if there is no hygrometer?
Knowing what the normal relative humidity in the room is optimal for a person, you should be able to check the current level of humidity. If there is no hygrometer and it is not possible to use it, you can try an experiment with a glass of plain water. First, they collect liquid in a container and put it in a refrigerator, wait three hours. Then the item is taken out of the refrigerator and placed in the room. You need to choose a place remote from all the main sources of heat. Then, for ten minutes, they control how the glass changes outwardly, what happens to the container. The walls can fog up and dry out quickly. This indicates increased air dryness. If the walls remain wet for a long time, we can talk about normal environmental parameters. Sometimes the condensate that appears on the walls of the glass drains literally in streams. This indicates an increased level of humidity.
Using a spruce paw is no more difficult. To check whether adjustment of normal humidity in the room is necessary, the measurement is carried out using a tree paw about a third of a meter long. The item is attached to a wooden surface and the position of the part not fixed to the base is marked. After some time, they return to the branch with which they are experimenting, and check how its position has changed. The branch may fall slightly if the air is moist, remains in the same position at normal rates.
Christmas tree: used in different ways
Another option is known to check the degree of humidity in the room. To do this, you need a fir cone. In the room, choose a suitable place, remote from heat sources, put a lump and leave for a while. If the scales are compressed, the humidity is increased. While maintaining a stable initial position, they speak of a normal level of humidification. If the scales are revealed, it is safe to conclude that the atmosphere is dry.
Technically and accurately
To check what the air quality is, use the Assman chart - a reliable and accurate way. Normal indoor air humidity must comply with the above parameters. An accurate thermometer is required to use the table. Check the level of heating of the environment in the room, record the data, wrap the thermometer with a damp cloth and wait about five minutes, then record its indicators again. In the table you can find both of the obtained values. At the intersection of the rows and columns allocated to them, indicators of the humidity in the home are seen.
However, the simplest and most accurate option is a hygrometer. It can be bought in many stores, but the product is quite inexpensive. There are several types - film and weight instruments, hair, weight. Electrolytic models are quite popular. Good and fairly accurate results are shown by the use of condensing devices. Reliable ceramic varieties have proven themselves. The display usually has a scale of 20 to 90 units. The error is necessarily specified: usually no more than five divisions. If it is assumed that the atmosphere in the room under study is very high, you need to select a device with protection from water. This will eliminate the negative effects of condensate and damage to the unit.
Importance for different ages: for the smallest
It so happened that most often parents of young children think about observing normal humidity in the room, adjusting this parameter. Usually this happens under the impression of a pediatrician’s consultation explaining how important it is for the baby’s health to maintain optimal environmental parameters. A specific thermoregulation system is inherent in a child’s body, straying in conditions of excessive air dryness. The child exhaled is 100% hydrated and warmed to the temperature of the child’s body. If the surrounding space is filled with dry air, the body needs large volumes of water to moisturize the atmospheric gas entering the body. Excessive loss of water leads to dehydration and adverse effects, diseases, including severe ones.
In summer and winter, normal humidity in the room used as a children's room is 50-70%. The temperature level should vary around 24 degrees. At night, it is advisable to cool the air a little - not lower than 19 degrees. Such parameters of atmospheric gas will provide optimal conditions for the growth and development of children, which means that the likelihood of colds will decrease. As observations have shown, just such a climate is optimal for children's comfort, so the child sleeps for a long time and in good quality, quickly falls asleep and gets enough sleep. To control the level of humidification and monitor it, it is worth putting an aquarium. The task of parents is to regularly do wet cleaning. In the cold season, it is advised to hang wet towels on the batteries. You can put a container of water. An even more effective option is a special humidifier or air wash.
Humidity: how to stabilize?
Knowing what is the normal humidity in residential premises, you can establish a system to support the degree of humidity of the atmosphere. It is pretty simple. The best option is a humidifier. In modern stores there are many different models. Their use allows you to control the quality of humidification of atmospheric gas. Many products are complemented by a small light bulb, so they are multifunctional and are used as nightlights. Modern stylish models are not just a useful acquisition, but also an aesthetic product that adorns the interior of the room.
Products differ from each other in power, dimensions, design, additional functionality. All these parameters determine the cost of the product. High-quality models can not only moisturize the air, but also purify it, ionize it. Some have a built-in thermometer, hygrometer that allows you to constantly dynamically monitor the quality of the environment. There is a special system of automatic switching on and off, triggered when the humidity level rises above the norm or drops to a critical value. The user himself programs the standard indicators at which the product will be activated and turned off. No special participation in the work is needed.
Would be fresh!
In order to maintain normal air humidity in residential premises, they must be regularly ventilated. This refreshes the atmosphere and fills it with additional moisture outside. This is especially true in the cold season: heating systems are actively working, as a result, there is practically no moisture in the atmospheric gas. Experts recommend airing the rooms three times daily or more often. The first time the air is changed, waking up in the morning, then again open the windows closer to the middle of the day. The final event is in the evening, shortly before bedtime.
Another measure to keep the air fresh and moist is vegetation. Many people like to decorate window sills with flowers, but not everyone thinks that in addition to beauty, they are also useful. The leaves generate oxygen under the influence of sunlight, in parallel, a small amount of moisture evaporates. The owner regularly wateres his pets, and part of the water spent on it evaporates, stabilizing the moisture content of the environment.
What to try?
What should be the normal air humidity in the room is already indicated above, as well as simple folk remedies for checking the parameter are given without additional equipment. But how can you make the air a little wetter if there is no way to put a humidifier, and it is not possible to take care of the flowers for flowers? According to experts, it is worth drying clothes in the apartment, especially in the cold season. So the level of humidity will be slightly higher, and the product will probably dry quickly. In order to reduce the temperature in an overheated house, at the same time to stabilize the level of humidity of the gases, you can hang towels on the batteries. They use simple baths. Products are thoroughly moistened in water and regularly re-moisturized.
Knowing what should be the normal humidity in the room, you can use containers with liquid to achieve it. We are talking about simple basins filled with water without additives. The container is placed on the floor so that it does not stumble, do not step into it accidentally, so that the basin does not get in the way of children or pets. Water will gradually evaporate from the tank, saturating the environment with moisture.
No less useful is the classic aquarium. This is a decorative and practical product. Water fountains have similar qualities. An aesthetically attractive product improves the composition of atmospheric gases, which means that all inhabitants of the house will be healthy, despite the vicissitudes of the season.
And if too much?
Knowing what normal indoor humidity is optimal for a person, you need to monitor the preservation of this parameter, not too carried away by the humidification of the environment. Sometimes it happens that the air is excessively filled with moisture. In some cases, this is due to reasons completely independent of the owner of the premises. So, if a person is very often forced to wash, surely there will be too humid air in his house. Similar effects are possible due to the large cellar. Several different solutions to the problem are known. The easiest option is to equip the bathroom with a high-quality powerful hood. If it is impossible to install such a system, it is enough to equip the room with a fan. This will certainly help to eliminate excess moisture.
Doctors, explaining which humidity in the room is normal, has a good effect on a person’s condition, and which is already redundant and harmful, recommend regularly ventilating the house. This helps to get rid of too dry and very important air, therefore it is useful in any case. In addition, fans, hoods, air conditioning systems in different parts of the housing will benefit.
About simple measures
To eliminate excess moisture in the house, all plumbing needs to be timely and properly repaired. When such products leak, it only exacerbates the situation. If at home the air is wetter than normal, you need to dry the laundry after washing only outside. Be sure to install a system for removing air from the stove. An oil heater will benefit. Perhaps this is the most effective way of air drying available to modern man. Equipping housing with such a device, you can forever forget about boring dampness.
To maintain normal humidity in a room that is prone to excess water, leave the curtains open on warm sunny days. Radiation from the sun helps to dry out the area.
Is it important?
Not every person feels normal humidity in the room or too low, excessively high.Because of this, it seems different that such a quality of the surrounding space is relatively unimportant, so you can not pay special attention to it. Since childhood, many of us are familiar with frosty patterns on windows. Condensation appearing on the windows during the cold season is a typical phenomenon for most homes. In fact, it indicates an excess of moisture in the atmospheric gas. Condensation usually occurs in the coldest parts of the home.

To maintain normal air humidity in a room that is prone to excess water in a gaseous environment, you can get a special device - a dehumidifier. Some use classic radiators, which simultaneously correct heating and humidity levels, but in the cold season, when the heating already works at full capacity, the radiator may be superfluous. In this case, special air conditioning will come to the rescue. Products have been developed that can simultaneously control the level of heating, cooling or heating the air as needed, and change the degree of moisture up or down. True, a high-quality and efficient climate system, having all of the above functions, will cost a lot.
An alternative to maintaining normal indoor air humidity is presented on the electronics market by dehumidifiers. These devices do not affect the heating of the medium. In their design there is a special tank for cooling the incoming air. This condenses the moisture in the gas. Condensate moves along internal paths into a vessel for storage, preventing re-evaporation. The air cleared of water moves to a premises.
About technical aspects
A classic dehumidifier can remove several liters (sometimes several tens of liters) of water from the air. As soon as the internal capacity is full, the product stops working. Disabling is automatic.
There are two main varieties: stationary models and portable. If you need to control the level of humidification in the room constantly, the first option is optimal. The second is good if you need one device for a consistent change in air quality in different parts of the home.
