You wear gloves and not mittens
Mittens actually keep your hands warmer than gloves, since your fingers have skin-to-skin contact and can share body heat. Also avoid wearing anything made of cotton, which absorbs moisture and can make your hands even colder.
You think only your fingers and toes can get frostbite
Because we’re so concerned with keeping our fingers and toes warm, we may forget about some other potentially problematic places that could get frostbite. Your nose, ears (especially earlobes), cheeks, forehead, and even shins could be target areas if they’re exposed to the cold for too long.
You don’t check the color of your skin
Your skin changes color depending on what stage of frostbite you have. The first stage, also called frostnip, causes your skin to turn red and numb, but doesn’t leave permanent damage. Superficial frostbite turns the skin pale or white. If your skin begins to feel warm at this point, it’s time to take serious action and get treatment for frostbite. If left untreated, the skin tissue could turn black and die, and joints or muscles may lose function.
