Hypothermia is the condition your body is in when your body temperature drops 4° F (2° C) or more below normal. If the body temperature sinks lower, body functions slow down and you risk freezing to death.Normal body temperature ranges from 97.2° F (36.2° C) and 99.5° F (37.5° C). Hypothermia can set in and cause your temperature to drop below this range under the following circumstances:
- If you stay in a cold indoor environment for a prolonged time.
- If you are unprotected against cold, windy, or snowy outdoor elements.
- If you stay in cold water too long.
- Hypothermia may also follow a heart attack or stroke.
Two groups are at higher risk for contracting hypothermia: young children and the elderly. Both groups use up their energy reserves quickly and are not well enabled to maintain a steady body temperature in cold climates.
Hypothermia often occurs when something prevents you from moving around and being alert. Car accidents, tranquilizers, and sedatives are all examples of things that can put you at higher risk.
