Cold injury can occur whenever air temperature is below freezing (32 degrees F). Freezing of the skin surface is called ‘frost nip‘. When freezing extends deeper though the skin and flesh, the injury is called ‘frostbite‘.

Hypothermia is a life threatening condition in which deep-body temperature falls below 95°F (normally 98.6°F).

While you can get hypothermia even during relatively warm conditions, when temperatures plummet the danger and risk of getting frost nip, frostbite, or hypothermia becomes even greater – because it can come on much faster.

Tips to prevent hypothermia…

Body temperature falls when the body cannot produce heat as fast as it is being lost.

Heat Loss Through The Head

At rest, the body core loses about 7 percent of its heat through the head.

When exercising, the head will lose more body heat which can ramp up to 50 percent heat loss, but the heat loss percentage will then diminish when you start to sweat and when your muscles start demanding more blood flow.

When in hypothermia however (shivering), core body heat loss through the head increases to as much as 55 percent and remains at this high level.
