Cold weather can affect your feet in several ways. You may notice redness, swelling, itching or a burning feeling around your toes after spending time outdoors. These symptoms may point to a condition called chilblains. Chilblains on toes develop when small blood vessels react abnormally to cold temperatures and then warm up too quickly.
Although chilblains usually improve on their own, they can cause discomfort and make walking difficult. Understanding their causes, symptoms and treatment options can help you protect your feet during colder months.
What are chilblains on toes?
Chilblains, also known as pernio, are small areas of inflammation that develop in the skin after exposure to cold, damp conditions. They commonly affect the toes, fingers, ears and nose.
When your feet become cold, the small blood vessels near the skin narrow to conserve body heat. If you warm your feet too quickly, these vessels may expand rapidly. This response can cause blood to leak into nearby tissues, leading to swelling and irritation.
Chilblains on toes often appear several hours after exposure to cold weather. They may affect one toe or several toes at the same time.
The condition is not the same as frostbite. Frostbite involves actual freezing and can cause more serious tissue damage.
Common causes of chilblains on toes
Several factors can increase your chances of developing chilblains.
1. Exposure to cold temperatures
Cold weather is one of the main triggers. Spending time outdoors without adequate foot protection can affect circulation in your toes.
2. Sudden temperature changes
Moving your feet from a cold environment into a very warm room can trigger symptoms. Placing cold feet directly against a heater may also make irritation worse.
3. Poor circulation
People with reduced blood circulation may have a greater chance of developing chilblains. Limited blood flow can make it harder for the body to regulate skin temperature.
4. Tight footwear
Shoes and socks that fit too tightly can restrict circulation. They can also aggravate chilblains on toes by creating pressure and friction around already irritated areas.
5. Damp feet
Wet socks and shoes can make your feet lose heat faster. Keeping your feet dry is an important part of winter foot care.
Some people may also have a higher risk because of underlying health conditions or increased sensitivity to cold.
Common symptoms of chilblains on toes
Recognizing the early signs can help you manage discomfort before it becomes more severe.
Common chilblains symptoms include:
- Red, purple or dark patches on the toes.
- Swelling around affected areas.
- Itching or burning sensations.
- Tenderness when touching the skin.
- Pain or discomfort while walking.
- Dry, cracked or blistered skin in more severe cases.
The affected areas may feel cold initially and become itchy or painful as your feet warm up.
Symptoms usually appear within several hours of cold exposure. They may last for one to three weeks, depending on their severity and how well you protect your feet.
Who is more likely to develop chilblains?
Anyone can develop chilblains, but certain people may face a higher risk.
These include:
- People who frequently spend time outdoors in cold weather.
- Individuals with poor circulation.
- People with low body weight.
- Individuals who smoke.
- People with conditions that affect blood vessels or circulation.
- Those who regularly wear tight or poorly fitting footwear.
If you experience repeated episodes of chilblains on toes, consider discussing the symptoms with a healthcare professional. Recurring problems may sometimes point to an underlying condition.
How to treat chilblains on toes
Most chilblains improve without medical treatment. However, proper foot care can reduce irritation and support recovery.
According to the NHS guide to chilblains, most chilblains improve within two to three weeks. The NHS also recommends warming the skin gradually and avoiding direct heat, such as hot water or radiators.
1. Warm your feet gradually
Move into a comfortably warm room and allow your feet to warm naturally. Avoid hot water, heating pads and direct contact with heaters. Rapid heating can increase irritation.
2. Keep your feet dry
Change wet socks as soon as possible. Choose breathable socks that help manage moisture and keep your feet comfortably warm to help soothe chilblains on toes.
3. Wear comfortable footwear
Choose shoes with enough room around your toes. Avoid tight footwear that creates pressure or restricts circulation.
4. Avoid scratching
Scratching irritated skin can cause cuts and increase the risk of infection. If your toes feel itchy, avoid rubbing or picking at the affected areas.
5. Protect the affected skin
Keep the skin clean and dry. If blisters develop, avoid breaking them. A healthcare professional can recommend suitable wound care if the skin becomes damaged.
6. Speak with a healthcare professional
If symptoms cause significant discomfort, keep returning or do not improve, seek medical advice. A healthcare professional may recommend a suitable treatment, including medication for itching or inflammation when appropriate.
How to prevent chilblains during winter
Prevention is especially important if you have experienced chilblains before.
Here are some practical ways to protect your feet:
- Wear warm socks: Choose comfortable socks that keep your feet warm without squeezing your toes.
- Choose proper shoes: Wear well-fitting footwear with enough room for your toes.
- Keep feet dry: Replace damp socks and avoid staying in wet shoes.
- Warm up slowly: Allow your feet to adjust gradually when moving indoors.
- Stay active: Regular movement, such as walking, can support healthy circulation.
- Avoid smoking: Smoking can affect blood circulation and make cold-related foot problems harder to manage.
- Maintain a comfortable indoor temperature: Avoid exposing your feet to sudden temperature changes.
These habits can help reduce your risk of developing chilblains on toes during colder months.
When should you see a healthcare professional?
Chilblains often improve within a few weeks. However, certain symptoms need professional attention.
Arrange an assessment if:
- Your symptoms do not improve after two to three weeks.
- Chilblains keep returning.
- You develop open sores or blisters.
- The affected area becomes increasingly painful.
- You notice signs of infection, such as spreading redness, warmth, pus or fever.
- Your toes develop persistent colour changes or unusual numbness.
People with diabetes or reduced foot sensation should seek professional advice promptly when they notice new skin changes or wounds.
A healthcare professional can examine your feet, assess your symptoms and determine whether another condition may be causing the problem.
Protect your feet with proper winter care
Your feet need extra attention during colder months. Chilblains can cause itching, swelling and discomfort, but simple changes to your daily routine can help protect your toes.
Avoid sudden temperature changes, keep your feet dry and choose comfortable footwear. Pay attention to unusual skin changes and seek professional advice if symptoms persist or become worse.
