Chilblains (Sardi Se Ungliyan Sujna): Home Care Without Burns
Itchy, swollen, red-purple toes after a cold day are usually chilblains, and the habit that makes them worse is the one almost every desi home has: holding frozen feet up to the heater or dipping cold hands straight into hot water. Warm up slowly instead, keep the feet dry and loosely wrapped, and most chilblains settle on their own in one to three weeks. This guide covers the home care that works, the signs that it isn’t chilblains at all, and when to see a doctor.
In brief
- What it is: small blood vessels in the skin reacting badly to cold followed by sudden heat.
- Where: toes most often, then fingers, heels, ear tips and nose.
- Looks like: red or purple swollen patches that itch and burn, worse in the evening.
- Key rule: warm slowly; never straight onto a heater, hot bottle or hot water.
- Usually lasts: 1 to 3 weeks. Longer, or broken skin, means a doctor.

What chilblains are (sardi se ungliyan sujna)
Your skin has tiny blood vessels that tighten when it’s cold, to keep warmth in the core, and when cold toes are suddenly heated those vessels open faster than they can cope with, so a little fluid leaks into the tissue around them. That leak is the swelling, the colour and the maddening itch.
It isn’t frostbite. The skin never freezes.
It happens in ordinary damp winter cold, well above zero, which is exactly the weather of a North Indian or Punjabi January inside a house with cold marble floors. The medical name is pernio. In Urdu and Hindi people just say the fingers or toes have swollen from the cold.
Who gets them
- People living in cold, unheated houses, especially with bare floors.
- Thin people and teenagers, girls more than boys.
- Students in hostels, where rooms stay cold and socks stay damp.
- Anyone with poor circulation, or who smokes.
- People who wash in cold water many times a day and then warm their hands at a flame.
The cold starts chilblains. The sudden heat afterwards finishes the job.
Myth: hot water and the heater are the best first aid
This is the big one. Feet ache with cold after a long evening on a bare floor, so someone kindly brings a bucket of steaming water or drags the heater right up to the charpai, and for about five minutes it feels wonderful. Then the itch arrives. Fast heat is precisely the trigger that forces the vessels open too quickly.
People believe it because the relief is instant and the damage shows up later, so nobody links the two. Gentle warmth is the answer, the kind you get from a warm room, dry socks and time.
Chilblains home remedy: warm slowly, step by step
- Come in from the cold and take off damp socks or gloves at once. Wet fabric keeps pulling heat out.
- Dry the skin gently, pat, don’t rub, including between the toes.
- Put on dry, loose woollen or thick cotton socks and sit in an ordinary warm room. Give it 20 to 30 minutes.
- If you want water, use lukewarm water only, about body temperature (roughly 37 °C), for 5 to 10 minutes, then dry well. Test it with the elbow.
- Keep feet at least a metre from any heater, and never on a hot water bottle or electric blanket.
- Don’t scratch. A cool, damp cloth for a few minutes calms the itch without breaking the skin.
- Moisturise with a plain, unscented cream or a little petroleum jelly once the skin is dry, morning and night.
- Walk about indoors for a few minutes every hour; moving legs keep blood flowing.
That’s most of it. Chilblains usually calm down within 1 to 3 weeks as long as the new cold-then-heat shocks stop, which in practice means changing the evening habit of the whole household, not just the person with sore toes.
Best socks and gloves for chilblains
Loose beats tight. A tight sock, a snug school shoe or a thick elastic band at the ankle squeezes the same small vessels that are already struggling, which is why two thin loose pairs often feel warmer than one tight thick pair.
- Socks: wool or wool-blend, or two thin cotton pairs, in a size that leaves toes free. Change them if they get damp.
- Indoor chappals or slippers with a thick sole over cold floors. Bare feet on marble or tiles are a common trigger.
- Gloves outdoors and on the bike or motorbike, where wind chill hits the fingers hardest.
- A shawl or cap for ears and the whole body. A warm core sends more blood to the fingers and toes.
For general cold hands and feet, the kind that are cold but not swollen or itchy, we have a separate guide to cold hands and feet in winter. If your hands and heels are cracking too, the 7-day dry hands and feet reset is a gentle week-long routine.
Chilblains cream: what the tubes actually do
Pharmacies and online shops sell creams labelled for chilblains. Most of them are moisturisers with a mild warming or soothing ingredient. They help in the way any good cream helps, by keeping the skin soft, reducing cracking and making it less itchy, but on their own they don’t shorten chilblains much. Keeping the feet warm, dry and free of heat shocks matters far more.
Don’t put a “warming” rub or a menthol balm on broken or blistered skin. Stop any cream that stings. Stronger medicines exist for severe or repeated chilblains, but a doctor decides on them after an examination.
Many grandmothers rub mustard oil into cold feet and pull on thick socks before bed. The oil works as a simple moisturiser and the rubbing brings gentle warmth, which fits the warm-slowly rule. Skip it on broken skin. Heating the oil until it’s hot, or using it with the feet held near the angeethi, undoes the benefit.
When it isn’t chilblains, and when to see a doctor
Several other problems look a bit like chilblains. Tell them apart first.
| What you notice | Could be | What to do |
|---|---|---|
| Numb feet that don’t itch, you have diabetes | Nerve or circulation problem | See your doctor; no direct heat |
| Fingers go white, then blue, then red | Raynaud’s | See a doctor, especially if new |
| Broken skin, an ulcer, pus or spreading redness | Infection | Doctor the same day |
| Patches lasting past 3 weeks, or out of cold season | Another skin or blood vessel condition | Doctor for a check |
People with diabetes need extra care. Numb feet can’t warn you when something is too hot, and a small blister can turn into a slow wound. Our guide to sugar in winter and diabetes foot care sets out the daily foot check.
See a doctor if the skin breaks, blisters, weeps or looks infected; if the patches are still there after 3 weeks; if they come back every winter badly; if fingers turn white or blue; or if you have diabetes, poor circulation or a condition like lupus. Never use a heater, hot water bottle or electric blanket on numb or swollen feet. A burn from one needs cool running water for about 20 minutes and then medical advice. Pregnant women and children with painful, blistered chilblains should be checked rather than managed at home.

Chilblains questions people ask
How do you get rid of chilblains fast at home?
Warm the area slowly in a warm room with dry, loose socks, moisturise twice a day, and stop scratching. Avoid the sudden heat of a heater or hot water. Most chilblains fade within 1 to 3 weeks when the cold-then-heat shocks stop.
What is the first aid for chilblains?
Get out of the cold, remove damp socks, dry the skin gently and let it warm up slowly under loose covering. Lukewarm water, not hot, is fine for a few minutes. Keep the area away from heaters.
What are the best socks for chilblains?
Loose wool or wool-blend socks, or two thin cotton pairs, that don’t squeeze the toes. Change them as soon as they get damp, and wear thick-soled slippers on cold floors.
Is it OK to put chilblains in hot water?
No. Hot water makes the vessels open too fast, which brings on more swelling and itching. Lukewarm water around body temperature is gentler, and a warm room with dry socks works as well.
Do chilblain creams work?
They help mainly as moisturisers, keeping the skin soft and less itchy. They don’t do much on their own without keeping the feet warm and dry. Don’t use warming rubs on broken skin.
How long do chilblains last?
Usually 1 to 3 weeks. If they last longer, keep coming back, or show up outside winter, see a doctor to rule out other causes.
Can chilblains happen on fingers?
Yes. Fingers are the second most common spot after toes, often in people who wash in cold water often and then warm their hands at a heater or flame.
Are chilblains a sign of diabetes?
Not by themselves; healthy people get them. But numbness, slow-healing sores or colour changes in the feet of someone with diabetes need a doctor, not home care.
Can children get chilblains?
Yes, especially in cold houses and schools. Keep their socks dry, keep them away from heaters and see a doctor if the skin breaks or they’re in a lot of pain.
Is mustard oil good for chilblains?
It can work as a basic moisturiser on unbroken skin, rubbed in at room temperature. Don’t heat it, and don’t use it on cracked or blistered patches.
