In all cases of cold-induced injury, the patient should be slowly warmed to 22°–27°C to prevent reperfusion injury. Freezing injuries are treated with warming of the body’s core temperature and with the bathing of the affected body parts in warm water with added antiseptic agents.
What is the most common cold injury?
The most common non-freezing cold injuries are chilblain and trenchfoot. Trench foot occurs when tissues are exposed to temperatures from 32-60°F for prolonged periods of time (>12 hrs), whereas chilblains, which is a more superficial injury, can occur after just a few hours of exposure.

What is heat and cold injury?
Heat-related illnesses include the continuum of heat rash, heat cramps, heat exhaustion, and the potentially deadly heat stroke. Cold-related illnesses encompass a broad array of conditions ranging from soft tissue injuries like pernio, trench foot, and frostnip to the more severe effects of frostbite and hypothermia.Can you get ill from being in the cold?
Many people associate cold weather with the common cold. While the weather is not directly responsible for making people sick, the viruses that cause colds may spread more easily in lower temperatures, and exposure to cold and dry air may adversely impact the body’s immune system.

If the eyes are not protected with goggles in high wind chill conditions, the corneas of the eyes may freeze.

Hypothermia can be fatal.
