Perhaps each of us has our grandmothers and mothersthey were forbidden to sit in the draft, explaining that the wind inside the room could “give” us such an unpleasant illness as a cold. But how exactly can a draft cause this infectious disease? And does the wind have anything to do with it? Well, let's try to figure it out.
Why do we get a cold?
Not all of us have a really goodimmunity. Due to the high population density in large cities, residents of megacities most often suffer from infectious diseases. When a virus enters the body, immunity includes protection in the form of an attack of special cells that intensively produce interferon - a special cellular protein that raises body temperature. Our body is well aware that many types of pathogenic bacteria and viruses are not able to withstand even a slight increase in temperature, and therefore include their protection at the crucial moment. If the virus is strong, then cough, runny nose and other troubles can come after the temperature, which for several days can completely knock you out of the rut.

How does a draft cause a cold?
Due to the fact that all coldscaused by bacteria and viruses, a draft in itself does not make you sick. However, it is hypothermia of the body that can weaken the immune system, because instead of fighting bacteria that have entered the body, your brain will direct all its efforts to heating frozen parts of the body. In other words, any hypothermia carries a lot of stress for the body, and under stress, your immune system begins to work worse.
By the way, precisely in order to preventpossible hypothermia, we are taught from childhood to immediately remove wet socks. Despite the fact that the foot area is quite small compared to the total body area, getting wet, all clothes and shoes very quickly give off heat. As a result, the body is supercooled, immunity decreases, dormant viruses are activated and go on a counterattack, causing you to have a fever, runny nose and a breakdown.
Do you think we will stop one dayhave colds? Is it possible to create a universal vaccine against colds and flu? Let's try to discuss this important issue in our Telegram chat or on the Yandex.Zen channel.
