Experts Answer "What If" Questions

What if my child goes out in the cold with wet hair?

You'd have one chilly child. It's a myth that a cold head causes a head cold--only viruses and germs do that, Dr. Knazik says. However, staying out in the cold for 30 minutes or more with wet hair could put your child at risk for frostbite on her scalp or the tips of her ears, or even for hypothermia, so just be sure she takes the time to blow-dry before that long hike to school.
