First aid measures may prevent further heat loss and help the body
slowly warm up.
Remain calm. Fear or too much activity causes
sweating. Sweating can make you feel chilled.
Find shelter so you
can get out of the cold, the wind, or the water.
Remove cold, wet
Put on dry clothing, especially wool clothing
or a synthetic fabric that insulates well, such as polypropylene. Cover your
If dry clothing is not immediately available, you can try to

blanket or sleeping bag around you and another person and allow body heat to
Warm up under a heated blanket, if available.
Move around, but don't be so active that you sweat.
Whirl your arms around like a windmill to get your blood moving and warm you

contain caffeine or alcohol. Eat high-energy foods, such as candy. Do not give
food or drink to a person who is acting confused or responding
Try to avoid putting your whole body in warm water. As a
last resort, use a warm-water bath [100.4°F (38°C) to
105°F (41°C)] to rewarm if help
is not available and other home treatments are not working to warm you up.
Small body parts, such as a hand or foot, can be rewarmed by putting them in
warm water. Do not put anyone who is not fully awake and alert into a warm

Be aware that if you (or the person) sit in front of a

Avoid activities that can further damage
Do not rub or massage frozen skin.

worse if your skin freezes, thaws, and then refreezes.
Do not walk on frozen feet if possible. However, it is better to walk on
frozen feet than to thaw your feet if there is a chance they will

Putting cold hands, feet, or ears in warm water
[104°F (40°C) to
108°F (42°C)] for 15 to 30
minutes. Do not use water above
