What are the first aid techniques for frostbite?

With frostbite, tissue death and damage occur. These are mainly limbs, ears, nose and soft tissues of the face. In case of frostbite, it is necessary to take the victim to a warm room. He must take off his outer clothing, since it will be warmed up first, not the body. Also, you need to call an ambulance. While she is on the way, the victim should try to keep warm. But rewarming should be gradual and not with the help of high temperature, as it can only harm. Hot drinks are good for warming, but alcohol should not be used. Rubbing with alcohol is also prohibited.
