Acute Hypothermia


Hypothermia is a condition that develops when body temperature drops below 95˚F (35˚C). Acute means the condition starts suddenly, gets worse quickly, and lasts a short time. Hypothermia can happen if your body loses too much heat or cannot keep a constant temperature. Hypothermia is classified according to temperature. Mild is 90-95˚F (32.2-35˚C). Moderate is 82.4-89.9˚F (28-32.1˚C). Severe is below 82.4˚F (28˚C).


Follow up with your healthcare provider as directed:

You may need blood tests or other tests to monitor your condition. Write down your questions so you remember to ask them during your visits.

Prevent hypothermia:

  • Dress in layers. Wear gloves, a warm hat, and thick socks in cold weather. Wear socks and a warm cap when you sleep. Keep an emergency bag with a dry, insulating blanket in your car in case you get lost or injured.
  • Do not drink alcohol when you are outside in cold weather.
  • Try to keep your home heated above 64.4˚F (18˚C). A hot drink at bedtime, hot water bottle, or electric blanket can help keep you warm while you sleep.
  • Get up and move at least once an hour.
  • Ask family, friends, or neighbors to check on you in cold weather. Ask your healthcare provider about services that can help if you need shelter, warm clothing or food, or heating assistance.
