What blazon of injuries tin can be acquired by cold weather condition?

Wintertime cold and snowfall provide a number of opportunities to get outside and participate in activities such as skiing, sledding, and snowmobiling. However, without proper protection, cold weather-related injuries can occur fifty-fifty when temperatures are above freezing (32 F, 0 C). This is especially truthful if there are loftier winds or if wearable is moisture. In general, however, information technology is both the temperature and the duration of exposure that play a role in determining the extent and severity of cold conditions-related injuries. This information describes the unlike types of cold weather-related injuries, as well equally what to practice to prevent and treat them prior to reaching a health care professional person.

Cold weather-related injuries tin can exist divided into two general categories.

1. Weather that occur without the freezing of body tissue, for example,

• chilblains,
• trench foot, and
• frostnip.

2. Injuries that occur with the freezing of body tissue, such as frostbite.

Frostbite occurs when there is freezing of body tissue, and it is the most serious of the common cold weather-related injuries. Frostbite commonly affects the hands, feet, nose, ears, and cheeks, though other areas of the trunk may also be affected. This type of injury results from decreased claret flow and rut delivery to body tissues resulting in dissentious ice crystal formation, which ultimately leads to cell death. Upon rewarming of the affected tissue, vascular harm and complex cellular metabolic abnormalities lead to tissue expiry.

Damage to tissue is most pronounced when there is prolonged common cold weather condition exposure, the afflicted area slowly freezes, and the subsequent rewarming procedure is tedious. Repeated thawing and refreezing of the affected tissue is specially damaging and should always exist avoided.

Frostbite injuries can be classified as either superficial or deep, depending on the tissue depth of injury.

Superficial frostbite injuries involve the skin and subcutaneous tissues and deep frostbite injuries extend across the subcutaneous tissues and involve the tendons, muscles, fretfulness, and even bone. Superficial frostbite injuries have a better prognosis than deep frostbite injuries.

What are the signs and symptoms of frostnip?

Frostnip is a mild common cold weather condition-related injury that typically affects the face up, cheeks, lips, ears, toes, and fingers. Symptoms of frostnip commonly occur after exposure to cold weather. The area(s) may appear stake, be accompanied past burning, itching or pain, tingle, and feels numb. Simple rewarming restores normal color and sensation, and there is no subsequent permanent tissue damage.

Tight-fitting, constricting boots and footwear serve to exacerbate the condition. Trench foot does not require freezing temperatures, and can occur with temperatures of upward to threescore F (15.5 C).

The symptoms of trench foot may include pain, itching, numbness, and swelling. The foot expanse may appear cerise or blotchy (red and pale areas mixed together) or even bluish-blackness with advanced injury. Blisters and open up sores tin develop. In severe trench foot, the tissue dies and sloughs off, and the development of gangrene can occur, sometimes requiring amputation of the area(s) where the frostbite occured.
