Hypothermia - Symptoms

The signs and symptoms of hypothermia follow a typical course. Though the body temperature at which they occur vary from person to person depending on age, health, and other factors.

Some of the first signs of hypothermia may be lack of coordination, cold and pale skin, and intense shivering. As body temperature begins to fall, speech becomes slurred, muscles go rigid, vision problems develop, and the patient becomes disoriented.

At body temperatures below 90°F (32°C), heart rate, respiratory (breathing) rate, and blood pressure fall. Eventually the patient loses consciousness and may appear to be dead. At even very low temperatures, however, a person may survive for several hours. They can sometimes be successfully revived.
