Once you're in the cold water you only have 10 minutes before you start to lose muscle control to hands, feet, arms, and the harder you fight the greater the loss of heat from your core. In 1 hour you develop hypothermia and die. Once that soldier is out of the water the first thing he must do is strip naked and jump into snow to dry off then wrap in a dry blanket and fresh fatigues. Keeping wet clothes on greatly increases heat loss versus cold dry air.
no you can not train to beat heat loss, Cold is going to get you eventually no matter what. that being said what you do though is you condition your mind and your bodies reflexes not to place you into involuntary shock at the instant your body senses cold. A strong cremaster reflex helps because that will pull the boys up into the inaugural canal And anyone who has studied a few of the more advanced martial arts understands the cremaster muscle can be strengthened and the reflex can be improved some can even will the reflex into action.
People who are more at home living in sub zero temperatures are genetically different than people who live in the deserts the same as those who live in hot humid regions.
Artic training is more about learning how to survive and function in sub zero the same as desert training neither is about learning to live in either region for very long periods of time.
