Sometimes it is hard to tell if a person has hypothermia. Look for clues. Is the house very cold? Is the person not dressed for cold weather? Is the person speaking slower than normal and having trouble keeping his or her balance?
Watch for the signs of hypothermia in yourself, too. You might become confused if your body temperature gets very low. Talk to your family and friends about the warning signs so they can look out for you.
Early signs of hypothermia:
- cold feet and hands
- puffy or swollen face
- pale skin
- shivering (in some cases the person with hypothermia does not shiver)
- slower than normal speech or slurring words
- acting sleepy
- being angry or confused
Later signs of hypothermia:
- moving slowly, trouble walking, or being clumsy
- stiff and jerky arm or leg movements
- slow heartbeat
- slow, shallow breathing
- blacking out or losing consciousness
Call 911 right away if you think someone has warning signs of hypothermia.
