Cold injuries are divided into freezing and nonfreezing injuries (occur with ambient temperature above freezing). They include hypothermia, frostnip, chilblains, immersion foot and frostbite. Exposure to cold can induce Raynaud’s disease, Raynaud’s phenomenon and allergic reactions to cold.

What is the most common injury associated with severe cold exposure?

Frostbite is an injury to the body that is caused by freezing. Frostbite causes a loss of feeling and color in the affected areas. It most often affects the nose, ears, cheeks, chin, fingers, or toes. Frostbite can permanently damage body tissues, and severe cases can lead to amputation.

Which cold injury is the most severe and may result in a loss of body parts?

The most severe cold injury is hypothermia which occurs from excessive loss of body heat and the consequent lowering of the inner core temperature (internal temperature of the body). Hypothermia can be fatal.

What does frostbitten skin look like?

Signs and symptoms of frostbite include: At first, cold skin and a prickling feeling. Numbness. Skin that looks red, white, bluish-white, grayish-yellow, purplish, brown or ashen, depending on the severity of the condition and usual skin color.

What is a localized cold injury?

In localized cold injuries, the skin and underlying body tissue become very cold or freeze in very cold environments. Body parts that are commonly exposed to extreme cold are the most likely to be affected, such as the fingers, toes, earlobes, cheeks, and nose.

Can you get sick from being exposed to cold weather?

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.

What are the first signs that a person is suffering from hypothermia?

What are the signs and symptoms of hypothermia?

• Shivering.
• Exhaustion or feeling very tired.
• Confusion.
• Fumbling hands.
• Memory loss.
• Slurred speech.
• Drowsiness.

What symptoms indicate a patient needs emergency care for hypothermia?

• Shivering.
• Fatigue.
• Increased respiratory rate.
• Hunger.
• Nausea.
• Mild confusion.
• Some difficulty with speech and coordination.

What part of the body gets cold first?

The body’s response to cold The reduced blood flow to the hands, feet, ears, and nose causes them to feel cooler than, for example, the stomach or chest, as a result. The nose is likely to feel cold first when temperatures dip because it is composed mainly of cartilage tissue and does not have a lot of insulating fat.

What does a mild case of frostbite look like?

Superficial frostbite appears as reddened skin that turns white or pale. Your skin may begin to feel warm — a sign of serious skin involvement. If you treat frostbite with rewarming at this stage, the surface of your skin may appear mottled. And you may notice stinging, burning and swelling.

What are the symptoms of peripheral cold injury?

However, as a general overview, the signs and symptom of peripheral cold injury includes : Numbness and tingling. Burning and severe pain. White to blue discoloration of the skin. Redness and swelling of the affected part. Blisters, erosions and ulcers. Necrosis and gangrene. Loss of function of the affected part.

Do you get cold injuries in cold weather?

Cold injuries usually do not occur, even in extremely cold weather, if the skin, fingers, toes, ears, and nose are well protected or are exposed only briefly. The risk of cold injuries increases when the flow of blood is impeded, when food intake is inadequate, or when insufficient oxygen is available, as occurs at high altitudes.

What are the different types of cold injuries?

The two types of non-freezing cold injuries are chillblain (pernio) and immersion foot (trench foot). Although frostnip is a milder form of cold injury than chillblains, it is discussed further under freezing cold injury as it is a form of mild frostbite.

How is the severity of a cold injury determined?

Cold injury is dependent on the temperature of the environment or substance and the duration of exposure. The injury may also be determined by clothing and other other protective gear that can play a role in minimizing the severity of the injury. There are two ways of classifying cold injury.
