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 (hi-poe-THUR-me-uh) occurs as your body temperature falls below 95 F (35 C).

When your body temperature drops, your heart, nervous system and other organs can’t work normally. Left untreated, hypothermia can eventually lead to complete failure of your heart and respiratory system and eventually to death.

Hypothermia is often caused by exposure to cold weather or immersion in cold water. Primary treatments for hypothermia are methods to warm the body back to a normal temperature.


~ Symptoms

Shivering is likely the first thing you’ll notice as the temperature starts to drop because it’s your body’s automatic defense against cold temperature — an attempt to warm itself.

Signs and symptoms of hypothermia include:

  • Shivering

  • Slurred speech or mumbling

  • Slow, shallow breathing

  • Weak pulse

  • Clumsiness or lack of coordination

  • Drowsiness or very low energy

  • Confusion or memory loss

  • Loss of consciousness

  • Bright red, cold skin (in infants)

Someone with hypothermia usually isn’t aware of his or her condition because the symptoms often begin gradually. Also, the confused thinking associated with hypothermia prevents self-awareness. The confused thinking can also lead to risk-taking behavior.
