It is good to gain this experience in a relatively safe environment. You learn without the risks. Now you will be able to recognize it sooner and take the appropriate action if it happens in a not so safe environment.

Hi Bob.
People can become victims of hypothermia even in relatively mild conditions. It does not need to be in freezing water or a blizzard.
Illness or injury increases the risk a lot too.

Another thing to remember is that as your blood temperature drops you brain starts to malfunction.

IIRC, Florida has more hypothermia cases than any other state, mostly immersion hypothermias, I suppose.

I have heard of hypothermia fatalities where the official temperature never dipped below 53 F. Being wet and unsheltered from wind can get one in serious trouble
