Relax. You won't gain 10 pounds. It's a misconception that you'll need to go up a pant size in January. The average person gains only about a pound during the weeks between Thanksgiving and New Year's. That's no excuse to eat with abandon, though. (After all, gaining one pound every year can add up in the long run.) But a study published in the Journal of Social and Clinical Psychology notes that people who had an attitude of forgiveness and self-compassion after one high-calorie setback were less likely to give up and keep bingeing. So if you lose control with a dish of chocolate truffles, don't think, I've blown it. Might as well move on to the eggnog. Just forgive yourself for the truffles.

Don't skip meals. It seems logical: Forgo lunch; leave more room for pigs in blankets at the office party later. But arriving starved may result in overeating, and drinking on an empty stomach will give you a quicker buzz, which is more likely to lead to mindless munching. Eat normally during the day, and be strategic at the buffet. Don't bother with things you don't absolutely love. Splurge on something special (hint: It's not those cubes of Cheddar), then stop.

Superficial frostbite shows white and waxy skin with firm, soft tissue while deep frostbite shows signs of blotchy skin with a white to purplish tinge, numbness and solid skin over entire depth. Treatment for first and second degree frostbite includes warming the tissue with warm water or a warm hand over the involved area. This area will be extremely sensitive to further cold exposure and should be protected accordingly. 

The treatment for third degree frostbite is to transport the person to a medical facility immediately. There is often permanent damage with this type of injury.

Tips to avoid cold injury:

1. Cover all exposed surfaces in a cold environment.
2. Avoid contact with colder objects or cold wind.
