How Dangerous Dry Air In The Room Is?

What is dry air?

Many people mistakenly believe that dry air is hot air, but it is not. Dry air may be cold, but it is a disadvantage of water molecules in vapor form.

There are such things as "absolute humidity" and "relative humidity". Humidity is the total number of water molecules, which can be located in the air. Relative humidity is defined as a percentage. For example, the relative humidity is 60%, i.e. there is 60 percent of the moisture in the air that may be there in the accordance with the laws of physics.

Normal moisture content for humans is from 40 to 60 %. If the humidity is below 40%, which means that the air is too dry, it can lead to health problems .

Humidity in the room: how to measure

To measure humidity household hygrometer, which is a device that resembles a normal thermometer is used. This device is inexpensive, so it is advisable to buy it for home and office.

But if there is no hand hygrometer, you can use the following method, for which you will need a regular glass of water that needs to be put in the fridge for two hours. After two hours, the glass should be put on the table, as far away from heating appliances as possible and observed for five minutes. If the walls of the glass get fogged up, but in just a couple of minutes get dry, this suggests that indoor air is too dry, its relative humidity is below 40%. If the indoor air is of normal a humidity, the glass wall will remain wet for five minutes or more.

  • The respiratory system. From drying of the mucous membranes of the respiratory system, the whole body suffers, since at this point the person becomes particularly vulnerable to viral and bacterial infections  Especially dangerous is drying of mucous respiratory of children.
  • The nervous system. During breathing air is too dry, the body does not receive enough oxygen, which leads to hypoxia. There may be symptoms, such as high fatigue, dizziness, bad mood, depression .
