What to do if you get nipped
(HealthDayNews) -- Frigid air can cause exposed skin to become frostbitten. This is when the tissues in your skin freeze, creating a wood-like texture. The frozen area may turn whitish yellow.
If this happens to you, the Mayo Clinic recommends you first try treating it yourself: Immerse the entire foot, leg or other body part in warm bath water, about 104 degrees. Don't let the body part refreeze.
If the frostbite is hard and waxy or if the area doesn't return to its normal color after you've warmed it, or if it forms blisters, seek emergency care immediately.
