Air humidity is one of its most important characteristics.
Our bodies instantly sense not only temperature, but also humidity. In our modern age, we spend most of our time in apartments rather than in nature, so humidity is now relevant not according to the weather forecast—somewhere outside the window—but where we live, in our apartment. And these are often two different things.
Dry indoor air causes increased moisture loss through the skin and respiratory tract. This can lead to such unpleasant consequences as:
The main factor affecting indoor humidity is temperature. If you air out a room in winter, the air will become fresher but less humid.
The following increase air humidity:
The normal indoor humidity level for an adult is 40 to 60%.
Young children have increased heat-exchange processes, so they are especially sensitive to deviations from the recommended microclimate parameters. The ideal humidity in a child’s room is 50–60%, and if a child has an acute respiratory viral infection, it is recommended not to let it fall below 60%.
Indirect signs of low indoor humidity include the drying of plant leaf tips and electrical discharges from synthetic clothing.
How to reduce excessive humidity:
When indoor air is dry, the “transportation” of oxygen into the circulatory system becomes difficult. As a result, a person constantly feels sleepy and unusually tired, often without understanding where the poor feeling came from. When a person breathes dry air for a prolonged period, their susceptibility to various infections increases, hence the appearance of a runny nose in the morning. Because of dry air, the nasal mucosa and bronchial tubes cannot cleanse themselves as effectively as they can in air with normal humidity. As a result, the body easily succumbs to infections and various respiratory diseases. This is especially true of very young children, whose immunity is weaker than that of adults. There is a reason why even in newborns’ rooms it is recommended to hang wet laundry to make the air more humid.
Dry air is also harmful to skin health. When you spend a long time in a dry room, your skin becomes almost rubbery. This is because a lack of moisture accelerates evaporation from the skin. As a result, it quickly becomes rough and dry.

Dry indoor air causes increased moisture loss through the skin and respiratory tract. This can lead to such unpleasant consequences as:
- reduced elasticity of the hair, nails, and skin, accompanied by the appearance of microcracks, wrinkles, flaking, and dermatitis;
- drying of the mucous membrane of the eyes, with symptoms including itching, redness, and a sensation of “grit”;
- thickening of the blood, leading to slower circulation, weakness, headaches, reduced performance, and increased strain on the heart;
- increased viscosity of gastric and intestinal juices, causing slower digestion;
- drying of the mucous membranes of the respiratory tract, resulting in weakened local immunity and more frequent acute respiratory viral infections;
- an increase in the amount of respiratory allergens in the atmosphere, which should normally bind to droplets of liquid.
The main factor affecting indoor humidity is temperature. If you air out a room in winter, the air will become fresher but less humid.
The following increase air humidity:
- an aquarium;
- houseplants;
- wet laundry;
- containers of boiling water;
- faulty water pipes and plumbing.
- heating appliances;
- air conditioning;
- constant airing when the outdoor temperature is below -10°C
- interior items, especially upholstered furniture, toys, and carpets.

How to reduce excessive humidity:
- airing rooms frequently;
- installing exhaust fans;
- using air conditioners and heaters;
- keeping pipes and plumbing in good repair;
- avoiding drying laundry in the room;
- having an aquarium or decorative fountain;
- minimizing the use of heaters and air conditioners;
- hanging wet towels on radiators;
- periodically spraying water from a spray bottle;
- using a humidifier;
- regularly carrying out wet cleaning;
- growing a large number of houseplants.
