Scientists from the Netherlands came to the conclusion that kissing is not dangerous to health but rather help to strengthen the immune system and increase resistance to various diseases.
In ten seconds the French kiss a couple shares is not less than 80 million bacteria. Most of them do not pose any danger, but among them may be dangerous bacteria. For a long time it was believed that through a kiss can be infected with HIV, but it proved that this is impossible. However, many physicians continue to insist that kissing is dangerous.
A new study by Dutch scientists has shown that it is not. It turned out that the exchange of bacteria helps to strengthen the immune system when foreign bacteria enter the body, he immediately reacts and develops resistance. This process, when the kiss is much faster than under any other conditions. During the experiment samples in laboratory were found to have opportunistic and even disease-causing microbes, but the body of the partner responds very quickly and no danger of kissing are not.
