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.
References. Hypothermia is a dangerously low body temperature. The average normal body temperature is around 98.6 degrees Fahrenheit, or 37 degrees Celsius. If your body temperature drops to just a few degrees lower than this, your blood vessels in your hands, feet, arms, and legs start to get narrower.our temperature can drop gradually as your body is exposed to cold temperatures. This could happen if: 1  You spend a lot of time in a cold, unheated indoor environment. 2  You are outside in cold weather without proper protection against the cold, wind, rain, or snow.
