Cold weather is the primary cause of hypothermia. When your body experiences extremely cold temperatures, it loses heat more quickly than it can produce it. Staying in cold water too long can also cause these effects. The inability to produce adequate body heat is extremely dangerous.
If heat loss exceeds the ability of the body to produce the heat, body temperature decreases below normal levels. Hypothermia is a decrease in body temperature to 35 degrees C (95 Degree F) or below. Hypothermia usually results from prolonged exposure to cold environments.
