Q:

Dear 100 Hour Board,
I was wondering, why does my nose run when I go outside in the cold? I had it explained to me by one of my science teachers once, but I can't remember what she said. Is there any way to prevent it from happening? I'm running out of tissues!

A: Dear Lil' Sis,

When you go outside in the cold, the air in your nose is warmer than the outside air. This creates a steam-like affect inside your nose. Water drops condense, mix with mucus and run out your nose. Bonus fact: your nose runs when you cry because some of the tears go down your nasal passages and mix with your mucus.

There isn't much you can do to prevent cold weather nose drips. I don't think dropping your inner nose temperature to match the outdoors is a good idea. Just make sure you use those lotion-filled, super-soft tissues. No one likes a red, sore nose.
