Pain in the extremities may be the first early warning of danger to cold stress. This must be taken as a sign of danger to the farmer or anyone working or playing outside. End the exposure to cold immediately. Useful physical or mental work is limited when severe shivering occurs. In addition to hypothermia, frostbite can also occur during the winter months.
Frostbite is the freezing of the skin and underlying body tissues.
It occurs when part of the body is severely affected by temperatures well below freezing. The flow of blood to the affected area stops, and skin cells may be permanently damaged. Any part of the body can be affected, but hands, feet, nose and ears are at most risk. Wind chill is another variable to consider during this time of year. How cold the wind makes us feel is called wind chill.
