What are the signs and symptoms of hypothermia?

The signs and symptoms of hypothermia vary depending upon how severe the hypothermia becomes. In general, there is a sequence of symptoms:

  • In mild hypothermia, the person will shiver and their heart rate, breathing rate, and blood pressure will increase.
  • As the core temperature drops further, below 95 F (35 C), the pulse and breathing rates drop as does the blood pressure.
  • The person may experience apathy, confusion, slurred speech, and an inability to perform simple tasks.
  • As the core temperature drops further (below about 89.9 F or 32.16 C), shivering stops, the appears appears to be semi-comatose, and the heart rhythm may become irregular.
  • Below 82.4 F or 28 C, the person has no reflexes, and the heart's output capacity falls.
  • The person's pupils become dilated and the patient appears comatose or dead.

These signs and symptoms can appear rapidly (minutes) in individuals immersed in very cold water. They may appear more gradually (over several hours) in people that develop hypothermia without water immersion, but with exposure to cold environments. Some people will develop other signs of cold weather induced hypothermia by having extremities (hands or feet) show cold related damage such as frostbite. These symptoms can appear in men, women, and children.
