When your body is losing heat faster than it can create heat, you run the risk of becoming hypothermic; when your body temperature slips below 95 degrees Fahrenheit, your organs can no longer function normally. Hypothermia can be a serious risk to your life and your health. You can lose fingers, toes, and limbs from the cold, and you might suffer from lasting damage. If you think that you might be growing hypothermic, then your situation is severe, and you need to increase your body temperature as quickly as possible.

This can be one of the most effective ways to quickly stabilize and raise your body heat. Your extremities - hands, feet, fingers, toes - are usually the first parts of your body to get cold, but the situation is most...
