Frostbite: Tips for Prevent and Treat

What exactly is frostbite?

Frostbite is a potentially fatal condition when bodily tissues (such as fingers, toes, and ears) harm due to exposure to cold weather or cold water. It is more prone to occur during the winter, in windy conditions, and at high altitudes. Even if exposed skin is frostbitten initially, it can occur even if the skin is covered.

How cold must it get to cause frostbite, and how long does it take to develop?

Single-digit Fahrenheit temperatures are frostbite-causing. It’s critical to note that the colder the weather outside, you can get symptoms more quickly. Indeed, it can occur in as little as a half-hour or less when the wind chill is -15F (-26 C) or lower.

What distinguishes frostbite from hypothermia?

Hypothermia occurs when your body temperature falls below 95 degrees Fahrenheit (35 degrees Celsius). Your body temperature is usually around 98.6° F (37° C). Hypothermia is a more severe condition that affects the entire body than frostbite, which only affects specific areas of exposed skin. It occurs when a portion of the body freezes, causing damage to the skin cells and tissues. As with ice on a windshield, frostbitten skin becomes hard and white. Both hypothermia and frostbite are medical emergencies.

What is the cause of frostbite?

Frostbite occurs when the skin exposes freezing temperatures or water. Additionally, it can happen when exposed to temperatures that are not nearly as cold but for a longer time. If ice packs or cold metal are put directly on your skin, they can cause frostbite. It can also occur through clothing, even your fingers, if you are wearing gloves.

It occurs when the water in your skin freezes, causing harm to your cells and soft tissues on both a visible and unseen level. Typically begins in the extremities (fingers, toes, and ears). However, frostbite on the cheeks and chin is just as expected. 

Who is susceptible to frostbite?

You are in danger of frostbite if you have exposed skin in cold temperatures. Additionally, you increase your risk of suffering frostbite if you:

  • Take blood pressure medication.
  • Diabetes.
  • Smoke.
  • Have peripheral vascular disease, a dangerous blood vessel disorder.
  • Have Raynaud’s phenomenon (Raynaud’s illness), a condition in which blood vessels periodically narrow (or spasm).
  • Dehydration.
  • Have a physical or mental condition that makes it difficult to protect yourself from the cold (like fatigue, mental illness, heavy sweating).
  • Have consumed alcoholic beverages or narcotics.

Let’s examine the many stages of frostbite, its associated indications, and its symptoms.

Skin that is normal in appearance and sensitivity to cold

The skin is the biggest organ in the body and is composed of several separate layers. It shields you from harm and enables you to perceive sensations in your environment via your sense of touch.

Blood vessels are located all over the body, even in the skin. They are responsible for transporting blood to the various tissues of your body to maintain their health.

When cold, your blood vessels contract, narrowing to divert blood away from your extremities, such as your fingers and toes. This assists in maintaining your body’s core temperature. Over time, a lack of blood supply to these places can wreak havoc on your skin and surrounding tissues.

Your risk of frostbite increases if you experience any of the following:

Frostnip: frostbite in the first degree

Frostnip is the pre-frostbite stage. It is gentle and does not irritate the skin.

Your skin will turn red and feel cold to the touch if you have frostnip. If you remain in the cold for an extended period, your skin may become numb or have a prickling feeling.

Frostnip is treatable with simple first-aid procedures such as avoiding more exposure to cold and rewarming.

Rewarming performs by soaking the affected area for 15 to 30 minutes in warm (not hot) water. Avoid rewarming with heat sources such as stoves or heating pads, as they might result in burns.

You may experience some pain or tingling as your skin begins to warm up. To alleviate any discomfort, you can take an over-the-counter pain medicine such as ibuprofen.

Frostbite of the skin: The second degree

Your skin will begin to change color from a reddish to a paler shade at this stage of frostbite. It may seem blue in some instances.

Your skin may begin to produce ice crystals. As a result, when you touch the affected area of your skin, it may feel hard or frozen.

At this point, your skin may begin to feel heat, and you may see some swelling. This is a symptom that skin tissue damage is beginning. Although the tissues beneath your skin are intact, quick medical treatment is necessary to avoid additional injury.

Rewarming should occur immediately. Your doctor will prescribe pain medicine to alleviate the discomfort associated with rewarming. They’ll wrap the wounded part to protect it after rewarming. 

Following rewarming, the affected area may produce fluid-filled blisters. Your skin may appear blue or purple. Additionally, you may see swelling and have a burning or stinging feeling.

Your doctor may drain blisters if you have them. Additionally, if any blisters look infected, you will be prescribed antibiotics to treat the infection.

Many individuals can fully recover from superficial frostbite. Under any blisters or scabs, new skin will grow. However, some people may develop persistent difficulties due to frostbites, such as discomfort or numbness.

Frostbite of the third degree

Deep frostbite is the most severe kind of frostbite, affecting both the epidermis and the tissues beneath.

If you have severe, the skin in the affected area may appear blue or splotchy. It may experience numbness to external stimuli such as cold or discomfort. Muscles close to the damaged area may be unable to function effectively. Blood-filled blisters may also form in individuals who have sustained severe frostbite.

Frostbite that is severe demands immediate medical attention. As with superficial, your doctor will rewarm the affected area. They’ll administer pain medicine, wrap the affected area, and may administer IV fluids.

Additionally, if you have severe frostbite, you may take a drug called a “clot-buster.” Compelling episodes of frostbite might result in the formation of blood clots. This medicine may assist in increasing blood flow to the affected area.

The region will appear black and feel hard following rewarming. This is because the affected area’s tissue has died. Additionally, large blisters may occur.

As with some cases of superficial, those who have sustained severe frostbite may experience long-term complications such as pain or numbness in the frostbitten area, as well as increased sensitivity to cold.

Takeaway and preventative measures

Frostbite occurs when the skin and underlying tissues of the body injured by exposure to extreme cold.

It divide into numerous stages. Some, such as frostnip, inflict minor permanent damage to the skin and can be treated with simple first aid. Others, such as superficial and profound frostbite, require immediate medical attention to avoid irreversible damage.

Take the following precautions to avoid frostbite:

  • Maintain an awareness of the weather forecast. Avoid prolonged exposure to cold weather and direct contact with metal surfaces or water while out in the cold.
  • Dress warmly for the cold weather. Wear mittens or gloves, ear-protecting hats, scarves, sunglasses, or ski masks. 
  • Change off of damp clothing as quickly as possible.
  • Maintain adequate hydration and consume nutritional foods. Avoid alcohol, which might cause your body to lose heat more rapidly.
  • Recognize the symptoms of frostbite. Bear in mind that frostnip is a symptom of more severe frostbite. If you or another person appears to be suffering frostbite, seek immediate warmth and medical assistance.
