Now let’s look at the degree of frostbite. Signs of the first and lightest degree of frostbite is the redness of the affected tissues and a strong decrease in their sensitivity. These changes are reversible — after the normal temperature regimen is restored, damaged skin for a while acquires a dark blue color with a blue tint, and after a while it begins to start itching or peeling off. Then all phenomena subside. It should be noted that further this area of the skin will be more susceptible to the cold.
