Humidity norm in the apartment: optimal performance

On the level of humidity in the room is largely dependent on the overall health and the health of the people residing in it. Despite the fact that the human body is worth 70% of the water, and we need it for life, its lack or excess of the same dangers. Today we tell readers HouseChief.ru online magazine, what are the rules of the humidity in the apartment, how to properly identify and stabilize if necessary.

What is the humidity of the air and its role in human

To move forward, you need to decide what is meant by the term "humidity". This concentration of water vapor in the air, which is determined by several variables. Water evaporating from the surface when heated land, lakes, rivers, seas and oceans, into the atmosphere and collects in the lower troposphere. Humidity is the absolute and relative. Absolute (from the Latin. absolutus - complete) - expressed in weight of water vapor per 1 m³ of air and calculated in grams. The higher the temperature, the greater the absolute humidity indicator of the increased amount of evaporated water.

Relative - steam mass ratio of the air to the maximum allowable value that can be contained at the same temperature. This indicator is calculated as a percentage. For example, if the relative humidity is 80%, it means that the air contains 80% steam, which can hold at a given temperature. For a man the optimal value is 40-75%, and the deviation from these parameters observed deterioration of health.

The correct calculation of the concentration of moisture in the air is necessary not only to produce weather forecasts, but also for the organization of storage paintings and books, The treatment of certain diseases, as well as for irrigation.

What affects the humidity

The level of moisture concentration in the air is influenced by different factors: on the street - one, and in the room - the other. For example, the humidity of the environment depends on the climate in the region, weather conditions, time of year and proximity to bodies of water. In areas on the water concentration in the air affects the moisture level on the street and temperature in the apartment, home, office, etc.

Also on the level of humidity in the room that affects heaters, air conditioning, upholstered furniture, Carpets, as well as frequent ventilation at an external temperature of -10 ° C, which leads to the air overdrying. And here houseplants, drying clothes, aquariums, Ornamental artificial reservoirs within the home, defective sanitary engineering and water tubesOn the contrary, lead to increased concentrations of water vapor in the air.

Optimal humidity in the apartment with GOST standards for different spaces and time of year

To create a comfortable climate in the apartments, houses and offices GOST 30494-95 "residential and public buildings. Parameters of indoor climate "provides optimum humidity values ​​for each particular room and time of year. moisture concentration is determined as a percentage of two values ​​- optimal and acceptable. The last value is the boundary that does not cause significant harm to human health, but it has a negative effect on mood, performance and overall health.

According to GOST ideal humidity level in the room in winter should be 30-45%, while in summer - 30-60%. Also, this regulatory document are regulated, and the maximum allowable value, namely the winter moisture concentration in the air should not be more than 60%, and in the warmer months - 65%.

Note! Doctors recommend to maintain the level of humidity in the range of 40-60%, in the year since independence.

Recommended humidity in the apartment during the warm season

In accordance with GOST 30494-95, summer optimum humidity level should be 30-65%. However, the walls of the buildings are heated, and there is an increase in temperature in the premises. A water from crane, a large number of houseplants and preparing food on plate help to increase the concentration of water vapor in the air, particularly if breather system Does not work properly.

The high moisture content of the air at high temperatures in summer prevents the normal heat transfer. Increasing humidity can lead to deterioration of health. To remedy the situation, you need to clean the ventsMore often ventilate the room and keep window open. You can also take advantage of special air dryers.

What should be the humidity in the apartment in winter

In winter, due to the fact that apartments and houses include heating, humidity level drops dramatically, and the air quickly becomes dry. This, in turn, leads to a multiplication of various germs and dust mites, dry out the skin and mucous membranes, increasing the load on the heart and digestive system malfunction.

We have already mentioned some humidity in the apartment is considered normal in the winter, namely the moisture concentration should be in the range of 30-60%. About the lack of humidity in the room prompt houseplants: the leaves begin to dry the tips. Remedy the situation will help humidifiers, about which we wrote in our online magazine.

We offer our video on how to increase the level of moisture in the winter, and whether to do it:

What humidity should be in the child's room

The child's body, unlike an adult, much more difficult to cope with the negative impact of the environment. Child until his immune system is not fully grown, quickly freezes or overheats, the easier and more exposed to colds and infectious diseases, as well as their complicated moves. It is therefore very important to create in the children's room healthy environmentWhich will provide support for the protective functions of the child's body.

The air in the room of the child in any case should not be too dry or wet. According to state standards, the normal humidity in the apartment should be in the range of 50-60%, while winter performance should not differ from the summer. However, there is a caveat: in the nursery necessary to maintain the temperature at 24 ° C, because if it is higher, then the moisture concentration in the air space of the order of 60% will resemble the tropics.

What humidity should be in the apartment for each room

We have already discussed what should be in the room rate of humidity, optimal for humans, both in winter and in the warmer months. However, you should know that in each room, depending on its purpose, must be supported by your level of concentration of moisture in the air. The following measures should not depend on the time of year.

appointment of premises	requirements
	The humidity level is in the range 40-55%. The room must be constantly ventilate and contain as little as possible of home appliances.
	The optimal level of humidity - 50-60%. It is necessary to avoid dry air to prevent drying of the mucous membranes, which leads to colds, especially in newborns.
	Norma humidity - 40-50%. This is the optimal level for man, pets and plants, but not for furniture.
	The level of moisture in the air should be in the range of 40-50%. However, this is the room with the specificity and high humidity, so you want to create a high quality for its normalization ventilation system.
	optimal humidity in the office It should be 30-40%. With an increase in this value is likely to damage the documents, but too dry air in the room also should not be.
	humidity rate for these rooms - 50-70%, as it is one of the most important factors for good plant growth.

How to measure the humidity in the apartment

We have already realized, the normal humidity in the room is very important for human health. However, in order to create a healthy microclimate in the house, you need to know how much water vapor is in the air, and to reduce or increase their concentration, if necessary. There are indoor humidity meters - hygrometers and sensors, but you can take advantage of special tables or folk ways. Consider the basic methods are available for determining the concentration of water vapor.

Hygrometer - a device for measuring the air humidity

Hygrometer - the most reliable instrument for determining the humidity in the room. It can be used to measure the concentration of water vapor up to 0.1%. The market offers a large number of different models, which differ from each other design and operating principle. However, it does not always have the opportunity to purchase the device, and many are interested in what else is measured humidity, if at hand are no special devices.

Assman psychrometer and table

Assman psychrometer - a fairly simple device for measuring temperature and humidity in the room, which consists of "dry" and "wet" or alcoholic mercury thermometers, independent from each other. To determine the concentration of water vapor in the air is necessary to take readings of the two thermometers, and to find the desired figure on a special table.

Determination of moisture content by means of a glass of water

This option does not allow to accurately determine the level of humidity in the room, but it is simple and accessible, because everything you need will find in every house - a glass of water and fridge. To measure the moisture level in the air must take a glass container with a liquid and for a few hours, place it in refrigerator until until it reaches a temperature of + 3... + 5 ° C. After that you need to put a glass in the room away from heaters. following signs tell about the level of humidity:

• beaker and covered with condensation fogged, and 5-10 minutes is completely dry - too dry air;
• 5-10 minutes after the refrigerator on the walls of glass formed large droplets of condensate and began to flow - too high humidity;
• glass surface after 5-10 minutes, not dry and not begun to flow - the average level of humidity.

How to increase the humidity in the apartment to the optimum level, and the harmful abnormality

favor of and the need for an optimum humidity level, we've already covered, but the threatening abnormalities? Lack of moisture in the air results in drying out of mucous membranes, fatigue, reduce the protective function of the immune system, significant deterioration of the skin and a feeling of discomfort. Excess moisture, in turn, causes the appearance of rhinitis, allergies and asthma. Category, the most sensitive to changes in moisture levels - children, and therefore it is very important to create a healthy environment in a place where they reside.
