As the colder months roll in, many people experience the unfortunate discomfort of chilblains. These small, itchy, and sometimes painful sores appear on the skin, typically affecting the toes, fingers, nose, or ears. While chilblains aren’t dangerous, they can be extremely uncomfortable, leading to frustration and, in some cases, infection. But what exactly causes them, and more importantly, how can you avoid them? Let’s break it down.
What Are Chilblains?
Chilblains (also known as pernio or perniosis) are an inflammatory skin condition caused by the body’s abnormal reaction to cold temperatures. When the skin is exposed to cold and then quickly warmed, the small blood vessels beneath the skin can expand too quickly, causing leakage of blood into the surrounding tissue. This results in the characteristic swelling, redness, itching, and sometimes blistering or ulceration.
Chilblains are most commonly seen in colder climates and during the winter months, but they can affect anyone, especially those with poor circulation or sensitivity to temperature changes.
What Causes Chilblains?
Several factors contribute to the development of chilblains:
Cold Exposure: The primary cause is the sudden warming of skin exposed to cold. This rapid temperature change can lead to a mismanaged response from the blood vessels.
Poor Circulation: People with compromised blood flow, including those with conditions like Raynaud’s disease, are more prone to chilblains. The smaller blood vessels may have difficulty responding appropriately to temperature changes.
Damp Conditions: Exposure to damp, cool environments can worsen the effects, as moisture combined with cold amplifies the body’s reaction.
Tight Clothing: Wearing restrictive shoes or gloves can hinder blood flow to extremities, making it easier for chilblains to develop.
Underlying Health Conditions: Those with underlying circulatory problems, autoimmune disorders, or diabetes are at higher risk of developing more severe chilblains.
Symptoms of Chilblains
Chilblains are relatively easy to identify due to their distinct appearance and symptoms:
Red or purple patches on the skin, often itchy and swollen
Burning or stinging sensation
Blisters or ulcers in severe cases
Tenderness in the affected areas
Symptoms usually appear a few hours after exposure to cold and typically last up to two weeks. However, if left untreated or if there’s repeated cold exposure, they can become chronic or lead to infections.
How to Prevent Chilblains
While chilblains can be a frustrating condition, the good news is that prevention is possible by making a few adjustments during colder months. Here’s how:
Keep Warm, But Gradually
Avoid sudden changes in temperature. If your skin is cold, warm it up gradually rather than using direct heat sources like radiators or hot water bottles. Wearing layers of clothing can help maintain an even temperature without shocking your system.
Protect Your Extremities
Fingers, toes, and ears are most vulnerable to chilblains, so be sure to keep them covered. Wear warm, well-fitting gloves, thermal socks, and appropriate footwear, particularly when heading out into colder environments.
Stay Dry
Dampness increases the risk of chilblains, so make sure your shoes, socks, and gloves remain dry. If you get wet, change into dry clothes as soon as possible to prevent prolonged cold exposure.
Boost Circulation
If you have poor circulation, keeping active during the winter months can help. Regular exercise and movement help improve blood flow and reduce the risk of developing chilblains.
Avoid Smoking
Smoking constricts blood vessels, which can worsen circulation problems and increase your risk of chilblains. Reducing or quitting smoking is not only good for your overall health but can also lessen the chance of cold-related skin issues.
Moisturise Regularly
Keeping your skin hydrated with moisturizers can help protect it from the effects of the cold. Some creams are specifically designed to protect against chilblains, particularly those that support circulation.
Treating Chilblains
If you develop chilblains, it’s important to treat them properly to avoid complications. Here are some steps you can take:
Gently warm the affected areas: Soak the area in warm (not hot) water for 10-15 minutes to increase blood flow.
Avoid scratching: This can irritate the skin further and lead to infection.
Apply soothing lotions: Use calamine lotion or an anti-itch cream to reduce discomfort. Prescription creams, such as those containing corticosteroids, may also be helpful.
Keep the area clean: This is particularly important if blisters develop. Clean the area with mild soap and water and apply an antiseptic cream to prevent infection.
Seek medical advice: If you notice severe swelling, pain, or signs of infection, contact a healthcare professional. In some cases, medication that improves circulation may be prescribed to prevent future episodes.
Chilblains may be a seasonal nuisance, but with proper care and prevention, they don’t have to interfere with your winter activities. By keeping your body warm, dry, and gradually adjusting to temperature changes, you can significantly reduce the risk of developing chilblains. If you do experience them, treating the affected areas with care will help speed up recovery and prevent complications.
