Keep hands and feet warm.
Lower temperatures cause blood to move toward the center of the body and away from hands and feet.
Keep your upper body warm, so that blood isn't drawn away from the hands and feet. Next to your skin, wear fabric containing some nylon. This moves moisture away better than 100 percent cotton fabrics. When the temperature is around 0 degrees F, warm the air you breathe by placing a scarf over your mouth.
