Describe HYPOthermia
the lowering of the bodys core temperature to a level where normal brain and body function are impaired
What are the signs someone is suffering from Hypothermia
What is normal body temp, and at what core temp will impairment begin
98.6 is normal, and 97 deg impairment begins
How do you avoid hypothermia

avoid cotton fabrics
stay well hydrated
snack often
How to treat a patient with hypothermia
