Know the signs of frostbite and hypothermia

Frostbite is an injury to the body that is caused by freezing. Frostbite is most common on exposed skin, such as your cheeks, nose and ears. It can also occur on hands and feet. Early warning signs include numbness, loss of feeling or a stinging sensation.

Immediately get out of the cold if you suspect frostbite. Slowly warm the affected area — but don't rub it because that can damage your skin. Seek emergency care if numbness doesn't go away.

Hypothermia is abnormally low body temperature. When exposed to cold temperatures, your body begins to lose heat faster than it can be produced. Exercising in cold, rainy weather increases the risk of hypothermia. Older adults and young children are at greater risk.

Hypothermia signs and symptoms include:

• Intense shivering
• Slurred speech
• Loss of coordination
• Fatigue

Seek emergency help right away for possible hypothermia.
