What is hypothermia?
Hypothermia refers to the condition in which the body temperature drops 4 degrees F (2 degrees C) or more below normal. Normal body temperature ranges between 97.2 degrees F (36.2 degrees C) and 99.5 degrees F (37.5 degrees C). At much lower temperatures, the metabolism (bodily functions) slows down. There is a risk of freezing to death.
How does it occur?

Hypothermia can occur when a person:

• spends a lot of time outside in cold weather, unprotected from the elements or in an unheated indoor environment
• wears cold, wet clothing for too long
• stays too long in cold water.

What can be done to prevent hypothermia?

There are a number of ways to prevent hypothermia. People who know they will be exposed to the cold should take the following precautions:
• Wear several layers of warm, loose clothing, especially headgear.
• Wear a protective waterproof and windproof outer garment.
• Keep their head and neck covered to help retain body heat.
• Stay dry.
• Do NOT drink alcoholic beverages.
• Be aware of the symptoms of hypothermia and emergency treatment for it.
• Have on hand space blankets (sheets of plastic and aluminum that help retain heat) and high-energy food in case of an emergency.

People over age 65 should take the following precautions during cold weather:

• Have someone check with them regularly during the winter. Check at least daily if it is very cold.
• Have their home properly insulated.
• Keep their living area warm (above 65 degrees F, or 18.3 degrees C).
• Wear layers of warm clothing to help keep body temperature even.
• Cover head and neck, even indoors, if they have trouble keeping warm.
• Stay dry.
• Be sure to have and use enough warm blankets.
• Practice good general health habits, such as getting plenty of rest and exercise and eating nutritious food.
• Keep a supply of nutritious food on hand that can be prepared easily.
• Eat hot meals and drink warm liquids throughout the day.
• Arrange for "meals on wheels" if they are unable to cook.
• Avoid alcoholic beverages.
• Check with their doctor to see if any medication they take regularly might increase their risk of hypothermia. (Drugs that reduce the body's ability to respond to cold include tranquilizers, cardiovascular drugs, sedatives, and antidepressants.)
• Take their temperature occasionally.
