What are frostbite and frostnip in children?

Frostbite is damage to parts of the body from freezing. It occurs when ice crystals form in the skin or in deeper tissue. The most common sites for frostbite are the fingers, toes, ears, nose, chin, and cheeks. Frostbite can cause serious injury and needs attention right away. It can cause long-lasting (permanent) tissue damage.

Frostnip is a mild form of frostbite. It doesn't cause permanent tissue damage. In many cases, it can be treated at home.

What causes frostbite and frostnip in a child?

Frostbite and frostnip are caused by exposure to cold temperature, usually below 32°F (0°C). How severe the symptoms are depends on several things. These include air temperature, length of time in the cold, wind chill, dampness, and type of clothing worn. Putting ice on the skin for too long can also cause frostbite or frostnip.

Children are more likely to get frostbite than adults. This is because they lose heat from their skin faster. A child is more at risk for frostbite and frostnip because of any of the below:

Playing outdoors for long periods of time
Having reduced blood flow from gloves, boots, socks, or other items that are too tight
Not wearing clothing that’s warm enough for the weather
Being in windy or wet weather, which causes rapid cooling of the skin and body

How is frostbite and frostnip treated in a child?

Frostnip can usually be treated at home. To do this:

Bring your child indoors.
Put them in dry clothes.
Warm their skin with warm towels or blankets. Or put the area in warm water (100° to 105°F or 38° to 41°C) until feeling returns. Make sure the water is not too hot.
Don't soak the area for more than 30 minutes. Don't rub or massage the skin.
Don't use direct heat, such as a heating pad or fire. This can burn skin.
If warming the skin doesn’t help, or if symptoms of frostbite occur, call your child's healthcare provider right away.

If your child has signs of frostbite:

Calm and comfort your child.
If your child’s feet are affected, carry them. Don't let your child walk.
Move your child indoors to a warm area as soon as possible.
Put them in dry clothes.
Call your child's healthcare provider or take your child to the emergency room. Frostbite can cause serious injury. It needs medical attention right away.

While waiting for medical attention:

Warm your child’s skin with warm towels or blankets.
Put the area in warm water (100° to 105°F or 38° to 41°C) until feeling returns. Make sure the water is not too hot.
Don't soak the area for more than 30 minutes. Don't rub or massage the skin.
Don't use direct heat, such as a heating pad or fire. This can burn skin.
Don't put snow on the skin. This does not help.
Put clean cotton or gauze between affected fingers and toes.
Don't touch any blisters.
Wrap warmed areas of the skin to prevent more injury. Don’t let the warmed areas freeze again.

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is. Your child may need treatment to remove dead tissue. This may be done with a procedure called debridement. Or it may be done with surgery. Talk with your child’s healthcare provider about the risks, benefits, and possible side effects of all treatments.

Tingling
Pins and needle feeling

Dress your child warmly in layers. Make sure ears, fingers, and toes are well covered.
