All of us familiar odor petrichor that occurs immediately after a rain, however, scientists have now covered the question of its impact on the human body.

In small quantities it carries no potential threat, however, some people may provoke the development of serious diseases.
How the substance is distributed in the air? Helped experiment. Scientists have adopted a fluorescent pigment and high-tech camera capable of high-speed shooting. After reviewing the videos, they found that every drop of rain, starting from the porous surface of the earth, releasing hundreds of bubbles with Jasmina. Mixed with oxygen, it is easily and quickly carried by the wind for hundreds of kilometers.
In General, the results obtained, experts believe, should not provoke people have a phobia against rain. With a strong immune system to catch a relatively rare disease even in the rainy season will not be easy, and advanced methods of therapy and does not leave him no chance.
