The humidity rate in the apartment is an important condition for a comfortable stay. Few of us think about it, however, this indicator is no less important than lighting and noise level. Not only the condition of the room, but also the furniture, household appliances, and most importantly, the health of the residents themselves, depends on its observance.
The negative side of increased dryness
So, what does the humidity rate in an apartment affect? First of all, it is precisely its decline that is more dangerous, or rather, dry air. It provokes an accumulation of a large amount of dust, and, therefore, the following health problems:
- Exacerbation of sinusitis and the growth of bacteria on the nasal mucosa.
- Decreased immune system function.
- Decreased vitality and general tone, the formation of the effect of chronic fatigue.
- Deterioration of the skin condition, decrease in its moisture level, manifestation of signs of early aging.
- Eye fatigue, a feeling of dryness and discomfort.
- The development of allergic reactions.
- Difficulty in treating current infections (especially in the nasal cavity).
The negative side 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 trouble was and remains central heating, which shamelessly dries the air. In addition to it, working household appliances, processes in which a person participates (cooking, ironing, washing, etc.) can also influence this indicator. A significant role is played by weather conditions and, of course, the time of year.
It should also be noted that if the humidity rate in the apartment is exceeded, this can adversely affect the condition 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. If their spores get into the human body, infections and unpleasant consequences are guaranteed. 
Existing Norms
What is the humidity rate 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 fall 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 moisture rate in an apartment for a person, animal or thing is significantly different. For example, household appliances, books, wood furniture are better preserved at a humidity level of 45 to 55 percent, and indoor plants - from 60 to 70. Based on this information, we can conclude that the air condition is extremely important not only for humans, but also for the living creatures surrounding him, and even objects.
The indicators are the same for each season. So, the humidity rate in an apartment in winter should fall in the range from 50 to 60 percent, similar figures are relevant for summer and off-season.
We determine the air condition
How is the air humidity in the apartment determined (normal or deviation)? For this purpose, a special device called a hygrometer has been developed. Externally, such a device can be performed in several variations (for example, an electronic board or clock). Install it in the back of the room, where there are no drafts and distracting external factors. This is done in order to reduce possible errors to minimum performance.
Folk techniques
There are several simple, but quite effective methods by which the humidity in the apartment is determined. The norm or non-compliance with it can be calculated even with an ordinary glass of water. So, a cooled glass container is placed in the center of the room and the evaporation of condensate is monitored. If dryness was reached in less than 10 minutes, you need to take urgent measures to moisten 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 humidity rate in an apartment be achieved if special devices are not used? There are a few simple ways you can also use it to combat dryness:
- Ventilation. Regularly open the window (and not the window) at any time of the year for 5-10 minutes.
- Diversify the flora indoors, plant more green plants.
- If there are no contraindications (asthma), get an aquarium.
- Do not forget to carry out wet cleaning, preferably at least 1-2 times a day;
- To neutralize the heat from the battery, water tanks installed near the heating devices will help.
The humidity rate in the apartment in winter is very problematic. Often, the simplest measures are not enough for this, because frosty air contains a minimum of moisture.
Special tools
How can I raise the humidity level in an apartment, the norm 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:
- Traditional. The principle of operation is based on the evaporation of water. The liquid is poured into the tank and pumped out using a fan. Filters must be changed regularly.
- Steam. Improves air quality due to steam temperature up to 60 degrees. Not suitable for rooms in which children live, has the ability to independently turn off.
- Ultrasonic. A popular novelty with many advantages. Differs in high quality and consumption of a small amount of electricity. As a rule, it is compact in size and absolutely safe for the health of persons living in the premises where it works. In case of violation of the operating rules, it can provoke the formation of a white coating on furniture and floor.
- "Air washing." The universal device is two in one (it resembles a vacuum cleaner in action), it purifies the air with the help of an ionizing element and increases air humidity up to 60 percent.
Modern devices allow not only to achieve the necessary indicators, but also to maintain them at the proper level. Such properties can protect the health of residents and ensure the safety of furniture and things in the apartment.
Each device has a certain range (suitable for the size of the room), which, as a rule, is indicated on the product packaging or in the attached instructions.
