We all know the expression - I need it as air. Without air, the very life of man is impossible. Here are some interesting facts about the air.
For normal life, the average adult man passes through his lungs about 20 kilograms of air per day. For this he makes 22 thousand breaths and exhalations. Of all the oxygen obtained with this, a quarter is consumed by the brain.
Air is a mixture of gaseous substances, under considerable pressure and cooling it passes into a liquid state.
The constantly deteriorating ecology and, especially, the colossal pollution of the atmosphere have a bad effect not only on people, but even on marine life. It has been established that dolphins inhabiting the coast of territories inhabited by people often die from the harmful effects of large quantities of chemical impurities in the air. Scientists, having opened such dolphins, discovered the similarity of their lungs with the lungs of miners.
Being outside the city, a person inhales much less harmful substances than in the city. Note here - the dust we inhale outside the city limits is also harmful to health.
It has long been noted that the air inhaled by a person at high altitude or depth has the ability to bring a person into a state resembling intoxication with alcohol or drugs. The reason for this is the special chemical composition of air under these extreme conditions. Oxygen forms a compound with nitrogen molecules, while obtaining the characteristics of a "fun" gas.
Record on the delay of breathing underwater staged on April 1, 2010 Stig Severinsen - he did not breathe 20 minutes and 10 seconds. To do this, he had to breathe 100% oxygen for half an hour before diving.
The Arctic poultry birds are a kind of living alarm for a dangerous level of air pollution. In very polluted air, they begin to breathe heavily. Therefore, in zoos during the smog, these birds are usually taken to rooms with a special air filtration system.
Considering interesting facts about the air, we will note - because of the discharged air at a high altitude people begin to experience oxygen starvation. Symptoms of this condition are increased emotionality, loss of self-control and a feeling of weightlessness.
The basis of inhaled air is oxygen. Forests, a significant part of which grows in the Amazon, produce 20 percent of oxygen. That is why forests are called the lungs of our planet.
