Wind chill are a measurement of how much the wind will impact the temperature of a persons skin. Wind chill can help to determine at what rate a person will lose body heat. While a person may feel cold due to the air temperature, the wind chill will make it feel more intense for the individual due to the rapid loss of heat from the skin.
Wind chill is important to understand as it can help to convey how quickly frostbite can occur. For instance, at 0°F with a wind chill of 20 mph, a person can experience frostbite after 10 minutes of exposure. However, at -20°F with the same wind chill, a person can experience frostbite in less than five minutes.
Wind Chill and Frostbite: What It Is and How to Stay Safe
Because the rate at which frostbite can occur is so rapid at these temperatures, a person must use the wind chill charts to determine the risks that they may encounter in a specific environment. These charts show the length of time that a person can remain in an environment before frostbite become a risk. Frostbite is the condition of the skin and the tissues beneath the skin to freeze.
Frostbite come in various stages of severity. The least severe form of frostbite is referred to as frostnip, which cause the skin to become red and prickly. If a person dont treat the early symptoms of frostnip, the condition can develop into superficial frostbite, which makes the skin appear waxy and white.
If a person continues to ignore the symptoms, deep frostbite can occur, which causes the skin to turn a black color and the joints in those affected areas to become stiff. Deep frostbite is a serious condition and can require an amputation of the affected body part. Deep frostbite occurs when the affected areas reach the deeper layers of the body.
The most common area to experience deep frostbite are the ears, nose, fingers, toes, cheeks and chin due to the way that these areas protrude from the body and lose heat more readily than the rest of the body. A person can recognize early sign of frostbite. For instance, a person can examine themselves for any areas where the skin has turned a grayish yellow color.
Additionally, the skin may feel hard and dry to the touch. Another condition that can indicate the presence of frostbite is numbness in those affected areas. This sensation are dangerous for the individual because it prevents them from feeling the pain that there skin is experiencing due to the cold temperature.
If a person feels these symptom, they should not rub the area where the frostbite is developing as this can damage the cell within the skin. Instead, a person should seek shelter and soak the affected area in warm water (around the temperature of the human body). A medical professional should treat any injuries resulting from frostbite whether they are more than a mild case of frostbite.
There are various piece of gear that can help to prevent frostbite. The gear help to keep the bodys heat and to keep moisture away from the skin. A person can wear a balaclava to protect their face, wear wool socks to wick moisture away from the feet, and wear thermal mittens instead of gloves as the mittens will retain more heat then the gloves.
Additionally, a person should ensure that they are dry as wet clothing will not provide the same level of insulation as dry clothing. Other factor that can lead to frostbite are smoking, illness, and exposure to high altitudes as these factor can lead to poor circulation of blood throughout the body. Finally, a person should pay attention to the individuals that they are traveling with to ensure that none of those individuals begin to feel numbness in their affected areas as this may be a sign that they are developing frostbite without being aware of it.
