You can see frostbite before you feel it

Our fingers and toes tend to get numb in the cold. If your extremities start to freeze, you won’t necessarily tell by the feeling. Early or mild frostbite can cause itching or tingling. After that, you will begin to notice signs visually, whether on yourself or someone else. In order of severity, look here for the color changes:

  • The skin turns light yellow or white (mild)
  • The skin becomes hard and looks shiny or waxy (medium weight)
  • The skin darkens and turns blue or gray (severe)

When to seek medical help

Go to an emergency room as soon as possible if you suspect frostbite. This includes any of the color changes mentioned above, as well as severe pain, bleeding, or blisters if your skin warms up.

G / O Media can receive a commission

Someone who has been cold enough to develop frostbite can also have hypothermia, a condition in which their body temperature has dropped. Hypothermia is more of an emergency than frostbite, according to CDC, so tend to hypothermia first. Severe frostbite may require amputation. Severe hypothermia can lead to death. People with hypothermia can be confused, tired, and speech impaired.

What to do while waiting for help

The first step in treating frostbite is to gently warm the affected area. Do not rub the skin;; Friction can help warm up a person’s fingers or toes, but it can also be more damaging to the skin.

If the skin is wet, remove wet clothing (such as socks or mittens) and dry the area. If possible go to a warm place; When you are outside, seek shelter.

To warm the skin, apply gentle heat from warm water or use body heat. For example, hold the person’s fingers against the core or the body of another person.

If you are using water, heat it to slightly above body temperature, around 105 to 110 degrees. (If you don’t have a thermometer, be comfortable. The water should feel like a warm bath, not hot soup.) Too hot water can cause burns to the person in addition to frostbite, which isn’t a fun combination.

Monitoring temperature is important because a person with frostbite may not be able to tell if a heat source is too hot. For this reason, hot water is safer than sitting by a fire or a space heater. If you need to use one of these heat sources, make sure that someone who can feel the heat can monitor the temperature to avoid burns.
