Dry air: what is it

in the air we breathe, water is present, of course in a gaseous state, ie, in the form of steam.So it is simple - the more water molecules in the air, the higher the humidity.

Dry air is not necessarily hot.Humidity may be too low, and when the room is cold

total number of these molecul

es - a so-called absolute humidity, it is not particularly significant.we are usually on the relative humidity (for sure many know this phrase from weather forecasts).

phrase "a relative humidity of 50%" means that water vapor in the air is about half of how much there is in principle they may be based on the laws of physics.

normal humidity for a man - a measure of 40 to 60%.If the water vapor in the inhaled air is less, this is what is felt as dry air.

Sensitivity to air dry individual.Someone obviously oschuschet dry air when humidity reaches 40-50%, and someone does not notice much of a difference, even if it has fallen even lower, and the symptoms arising explained by other causes.

How to measure humidity

Although household hygrometer - a device for measuring humidity - is not very expensive, it is still exotic for our apartments.But you can measure the approximate moisture content and improvised ways.Here are the most simple of them.Fill the water

ordinary glass and refrigerate for about 2 hours.After that put the glass on the table away from radiators and watch.If

wall steamed and dried for a few minutes, the humidity does not exceed 40%, that is, the air is too dry.

On the normal humidity level indicated by the fact that the walls are fogged over five minutes.If on the surface of the glass appeared large water droplets - the humidity is high, ie more than 60%.

  • nose and respiratory system.The drying of the mucous membranes of the nose leads to difficulties in breathing and nasal bleeding, often after sleep in a room with overdried vohduhom person wakes up with dry red with blood crusts in the nose.The drying of the mucous of the nose and the mouth leads to inefficiency protective barrier against infections, as a result of frequent rhinitis, pharyngitis, laryngitis.
  • nervous system.When the air is too dry, the body harder to get enough oxygen during respiration.This leads to all the standard symptoms of hypoxia - dizziness, high fatigue, apathy, depressed mood.
