You've heard it your whole life: Cold weather makes you sick. And sure, you need to stay warm in the winter, but can getting cold actually give you a cold? The answer: false. Colds come from a virus, not from the cold weather. In fact, you actually have a better chance of getting sick by staying indoors where the germs have been trapped all winter long.
What about this? You lose most of your heat from your head. Could it be true that a simple hat can keep our entire bodies warm and toasty? This, of course, is false. First, your head is only about nine percent of your body, and there's nothing special about your head. You will lose heat from any uncovered body part.
This one is for the athletes. You can get dehydrated when you exercise in the cold.
The answer: true! It's not just the sweat; you'll also lose more water through your breath when it's cold. And dehydration can be even more dangerous in the winter because it makes it harder for your body to stay warm.
Okay, one more. A little coffee or a sip of brandy will warm you right up! A lot of you might want this to be true, but the answer: false. Caffeine and alcohol actually make it harder for the body to produce heat and can drop your core temperature. You're better off drinking warm water. Even better, a sugared beverage, which helps your body produce its own energy. Warm decaffeinated soda, anybody?
