how long does it take for your body to get hypothermia?
 Hypothermia can occur at any temperature lower than normal body temperature. Factors like body fat, age, alcohol consumption, and especially wetness can affect how long hypothermia takes to strike. If you fall into water, the situation becomes drastically more dangerous.For example, in water 32.5 degrees Fahrenheit or colder, you might not survive more than 15-to-45 minutes.
