Dry air is dangerous

Radiators and nose

If the relative humidity of the air in the room comes close to 100 percent, there may be condensation on surfaces, leading to mold or rust. However, neither too dry air is not conducive to health.


Studies have shown that dry air has four main effects on the human body:

First Inhalation of dry air is a potential health hazard that can cause respiratory diseases such as asthma, bronchitis, sinusitis, nasal bleeding, or general dehydration, because it reduces the amount of body fluid during breathing.

Second Evaporation of moisture from the skin can cause skin irritation and itchy eyes.

3rd If the humidity is lowered, there is static - a slight shock when touching metal.

4th 'Subjective' air temperature is lower than that indicated by the thermometer, the body is cold.

To compensate for the lack of moisture in the air, the lungs produce more mucus. And just this extra mucus can cause problems for asthmatics. The simplest way to outwit this is drinking lots of water. Of course, that does not mean a lot of water during the examination of the asthma attack. Always take medicine that your doctor has prescribed the way you explained it.

The problem of dry air can be reduced by increasing the relative indoor humidity with a humidifier, ie. various methods of liquid evaporation from the container set. Can help even wet towels placed on the radiators.

In addition, the lower the temperature of the room, it is easier to achieve the desired humidity. Get a hygrometer to help you in determining the humidity.

Subjective sensation of heat and moisture

As to the subjective feeling of heat, it depends on the humidity of a room and can vary by five or six degrees at the same temperature, when the humidity changes from 10 to 80 percent. Because of the evaporation cools the human body when exposed to dry air. Feeling cold in the fall to reduce the humidity. For example, at a temperature of 21 degrees Centigrade a person will feel more cold if he entered the room with dry air after leaving the bathroom full of moisture.

For example, an air temperature of 24 ° C with a relative humidity of 0% people feel like 21 ° C. When the relative humidity of 100% the same temperature, we felt like it was 27 ° C.

The comfort temperature is achieved at 23 degrees with a relative humidity of 20% or at 21 degrees with 80% humidity. Relative humidity of 20% is common during the winter months in homes without a humidifier in which the central heating.
