The key to preventing hypothermia is to avoid extremely cold temperatures. If this is not possible, a person should try to stay away from windy areas where the windchill factor will be higher. Poor circulation can also worsen the condition, so very tight clothing and boots should be avoided.
Several medications and drugs can worsen the effects of hypothermia. Drinking alcohol and smoking tobacco can also aggravate the condition. When in a cold area, a person must get adequate amounts of food and liquid to maintain a healthy temperature.
Proper cold weather garments are also important. Windproof, water-resistant, layered clothing should be worn. All body parts should be protected, especially the hands and feet. A hat should always be worn in cold temperatures, since much heat is lost through the scalp.
