Ever since I was a kid, I’ve been fascinated by the Iditarod â€“ the dog race in Alaska that goes for miles and days. Well, both the drivers and the doggies have to be protected against the sub zero temperatures. I have read that if the temperatures are at zero degrees, they will slather Vitamin E on the dogs’ and people’s lips. If the temperature dips below that, they use petroleum jelly. The reason for this is because the Vitamin E, being fluid, can freeze. This makes me think that if you are walking in freezing temperatures, you should put Vitamin E on your lips if it’s very cold and Vaseline if it’s hideously cold! You might also want to smooth some on the edges of your nostrils, if breathing cold air hurts when you walk.
