Overview

Hypothermia means that your body loses heat faster than it can make heat. You can get it if you spend time in cold air, water, wind, or rain.

Most healthy people with mild to moderate hypothermia fully recover. And they don't have lasting problems. But babies and older or sick adults may be more at risk for hypothermia. This is because their bodies do not control temperature as well.

Make sure to follow your doctor's instructions for how to get better. It's also important to learn how to protect yourself from hypothermia in the future.

How can you care for yourself at home?

• Take your medicines exactly as prescribed. Call your doctor or nurse advice line if you think you are having a problem with your medicine.
• To prevent dehydration, drink plenty of fluids. Choose water and clear warm liquids until you feel better. If you have kidney, heart, or liver disease and have to limit fluids, talk with your doctor before you increase the amount of fluids you drink.
• Get a lot of rest at home, and stay warm.

To prevent hypothermia

• Avoid illegal drugs and too much alcohol. They can make you more likely to get hypothermia.
• Cover your head, hands, and feet in cold or wet weather.
• Try not to sweat a lot if you are out in the cold.
• Stay as dry as possible.
• Wear layers of loose-fitting clothing.
• Pack a kit in your car that has items you will need to stay warm. It may include fire-starting kits and a lighter, extra clothing, drinking water, and food. You also can bring a sleeping bag. Two people can warm up more easily by sharing the bag.

If you see symptoms in someone who has been in cold weather, keep the person warm and dry and get help quickly. Symptoms include shivering, cold and pale skin, and slurred speech.
