Next time you're making snow angels with the kids, don't wait for your nose to go numb before you call them inside for cocoa.
"Because children lose body heat more quickly than adults, they're at much greater risk for frostbite," says Nicholas Tsarouhas, M.D., an emergency medicine physician at The Children's Hospital of Philadelphia.
Frostbite is a serious form of skin damage that requires swift medical treatment, but it's preceded by frostnip, a milder skin issue you can treat at home. If your child's skin becomes red, or if he complains of pain or a tingly sensation, bring him indoors and gently warm the affected area by submerging it in lukewarm water or applying a warm compress. If skin becomes white, blistered, or waxy-looking, or if sensation doesn't return in a few minutes—signs of severe cold injury—call your child's doctor ASAP.
