Fluids increase your blood volume, which means that extremities will freeze more slowly. The National Safety Council advises that on long trips, people should eat often, drink often and rest often. Your ability to ward off cold-weather threats is directly related to what you put on your body and into it. Food produces heat for your body. The best defense when mother nature gets tough is to dress in layers, says Dr. Gray.
Loose layers are important, and mittens are better than gloves.
If your gloves or socks do get wet, then change them as quickly as you can. When dressing in layers, the one closest to your body is essential because it acts as a wicking layer than absorbs sweat. Polypropylene or polyester are smart choices. Cotton is worse than wearing nothing when it gets wet. The next layer should insulate your body.
