With the onset of autumn frosts dramatically increases the number of cases of SARS (severe respiratory viral infection or flu). We say, "cold". And it really is a disease associated with chill? Yes, that hypothermia leads to the onset of illness. Viruses that cause the common cold, a lot - more than one hundred. Most people are carrying these viruses, but they do not develop symptoms and do not give, because immunity is always on guard. Immune response keeps the virus in check. But only as long as happened hypothermia.
When we are outside in the cold weather, hypothermia primarily to the upper respiratory tract. Blood vessels of the nasal mucosa is compressed (reflex mechanism to retain heat). This reduces blood flow and, accordingly, the white blood cells. Virus protection is weakening, and they begin to grow rapidly, carrying "the conquest of territory."
