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
shivering (in some cases the person with hypothermia does not shiver)
