Hypothermia can set in between 15 minutes to 12 hours depending on how low is the outside temperature. Temperatures lower than 0 degree C or 36 degree F can cause hypothermia fastest. Cold water is more dangerous as the body temperature 25 times faster in cold water. An adult body is capable of survival from 45 minutes to 3 days after hypothermia sets in, through the 3 stages of hypothermia.
Hypothermia occurs when body temperature falls below its normal level which is 98 degree F or cooler. In the first stage of hypothermia is constricting of skin and blood vessels, increase in blood pressure and heart beat.
The 2nd stage will lead to a drop of body temperature by 2 to 4 degree C. shivering is violent, stumbling pace and mild confusion, victim becomes pale. Lips, fingers and toes may become blue. Body temperature drops below 32 degree C or 90 degree F in the 3rd stage which will cause the cellular metabolic processes to shut down and clinic death occurs.
