Since childhood, we are all used to that if you get hurt, you can blow on the wound and it will be easier. But doctors say that this method of self-medication does more harm than good and for that there are good reasons.

If you blow, less sore.

Even a small cut of the skin leads to pain and bleeding. To begin the healing process, first stop the blood. This occurs for a certain period of time, and during this entire period the dissected tissues continue to send to the brain the corresponding pain signals. If at this moment to blow on the wound, then first, even a weak airflow will begin to cool the skin, which creates an easy analgesic effect. Accordingly, due to, let a small fall in the local temperature in the inflammation focus, the vessels begin to narrow, which leads to a decrease and a rapid cessation of bleeding. And in the third, the air that a person blows, wet. In order for the wound to drag out more quickly, a normal moisture level in the tissues is needed, just as it exists in the human oral cavity. Dry skin heals badly and slowly. In the end, blowing on the wound really helps her to drag out.

What is the harm?.

Biologists say that in the oral cavity of any person, there are more than one hundred and eighty species of microorganisms. They live on the mucous membrane of the mouth, on the tongue, on the enamel of the teeth, in the interdental spaces, in human saliva and actively participate in the digestive function of man. Constant sterility in the oral cavity can not be achieved. Even if you use powerful antibacterial agents, after a while in your mouth bacteria will be found again. They constantly come with food, water, air, are brought from other parts of the body, delayed and actively multiply in favorable conditions for this, because the person's mouth is warm and humid.

Sixty years ago, Danish dentists from the Royal Dental College in Aarhus conducted oral cavity studies of eleven volunteers. They found that with the regular cleaning of teeth in the mouth of a healthy person, the pathogens of rotavirus infection, Koch's stick, causing tuberculosis, Staphylococcus aureus, streptococcus, pneumococcus, provoking severe inflammations of the pulmonary system and other terrible bacteria and viruses. While the host's body is not weakened by any serious ailments and its immune system is working, the pathogens do not multiply to a critical level that threatens their health, and in no way show themselves.

But if you blow on the bleeding wound, then along with the innocuous microflora of the oral cavity, wounded, inflamed skin edges are also infested with pathogenic bacteria and viruses, and here they behave differently. Microbiologists have long established that coagulated blood is the most favorable place for the propagation of any microorganisms.

As a result, on a wound that has just been prolonged, Koch's rod and staphylococci begin to actively divide, suppurations arise and the process of treating the wound is subsequently prolonged. Well, if a purulent wound is not treated, then at all possible development of an abscess and even a blood infection. Therefore, blowing on open wounds is very dangerous, since it is likely the emergence of rapidly developing infections.
