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.
WebMD defines hypothermia as a drop in body temperature from the normal average of 98.6 degrees Fahrenheit to under 95 degrees Fahrenheit. Hypothermia is usually associated with prolonged exposure to cold temperatures, but factors such as wind and wetness increase the chance of hypothermia, even in relatively warm conditions or waters.
