Health experts give tips to avoid hypothermia

Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia occurs as your body temperature passes below 95 F (35 C).

When your body temperature drops, your heart, nervous system and other organs cannot work correctly. Left untreated, hypothermia eventually leads to complete failure of your heart and respiratory system and to death.

Hypothermia is most often caused by exposure to cold weather or immersion in a cold body of water. Primary treatments are methods to warm the body back to a normal temperature.  Shivering is your body's automatic defense against cold temperature — an attempt to warm itself. Constant shivering is a key sign of hypothermia. Signs and symptoms of hypothermia include:

  • Shivering
  • Clumsiness or lack of coordination
  • Slurred speech or mumbling
  • Stumbling
  • Confusion or difficulty thinking
  • Poor decision making, such as trying to remove warm clothes
  • Drowsiness or very low energy
  • Apathy, or lack of concern about one's condition
  • Progressive loss of consciousness
  • Weak pulse
  • Shallow breathing

A person with hypothermia usually isn't aware of his or her condition, because the symptoms often begin gradually and because the confused thinking associated with hypothermia prevents self-awareness.

Typical signs of hypothermia in an infant include:

  • Bright red, cold skin
  • Very low energy

Call 911 or your local emergency number if you see someone exhibiting signs of hypothermia or if you suspect a person has had unprotected or prolonged exposure to cold weather or water. If possible take the person inside, remove wet clothing and cover him or her in layers of blankets.
