Burning Feet at Night: 9 Common Causes and What Helps

Feet that burn, sting or feel hot when you finally lie down are one of the most common reasons people search for foot help. The feeling is real, it can wreck your sleep, and it usually has a findable cause. Here is what is most often behind it and what you can do tonight.

Why it gets worse at night

During the day, walking, talking and everything around you compete for your brain's attention. In bed there is nothing else to notice, so signals from irritated nerves feel louder. Your feet also warm up under the covers, and body temperature and blood flow to the skin change through the night. That is why nerve-related burning so often peaks in the evening.

The most common causes

Peripheral neuropathy. Damage or irritation of the long nerves to the feet. It typically starts in the toes and soles of both feet, with burning, tingling, pins and needles or numbness. Read our neuropathy guide.
Diabetes or prediabetes. The leading cause of neuropathy. Years of high blood sugar damage small nerves and blood vessels. Many people first learn they have diabetes because of their feet.
Low vitamin B12. Common after 60, in vegans, and in people taking metformin or acid-reducing medicines for a long time. It is easy to test and treat.
Alcohol. Regular heavy drinking damages nerves and lowers B vitamins.
Athlete's foot. A fungal skin infection that burns and itches, usually between the toes, with peeling or cracked skin.
Tight shoes or nerve compression. Morton's neuroma (a thickened nerve between the toes) or tarsal tunnel syndrome can cause burning in one foot.
Kidney or thyroid problems, which can both affect nerves.
Some medicines, including certain chemotherapy drugs and antibiotics.
Erythromelalgia, a rare condition where the feet turn red, hot and painful, often eased by cooling.

What helps tonight

Cool, not cold. Soak your feet in cool water for 10 to 15 minutes, or use a fan at the end of the bed. Avoid ice directly on numb skin, because you may not feel cold damage.
Keep sheets off your feet. A pillow under the bedding or a bed cradle stops the weight of the covers pressing on sensitive toes.
Stretch and move. A short walk or calf and ankle stretches before bed improve circulation.
Breathable socks and shoes during the day, so feet are not hot and damp by evening.
Wind-down routine. Because nerve pain feels worse when you are tense and tired, a regular bedtime and less screen time can make nights easier.
Over-the-counter options. Capsaicin cream or lidocaine patches help some people with nerve pain; ask a pharmacist which suits you.

Can supplements help burning feet?

If a blood test shows low vitamin B12, correcting it can improve symptoms over months. Alpha-lipoic acid has the best trial evidence among nerve supplements for burning and tingling in diabetic neuropathy. Herbal formulas aimed at nerve comfort usually combine calming, sleep-supporting plants. They will not fix the cause, but some people find them helpful for comfort at night.

When to see a doctor

Book an appointment if the burning lasts more than a couple of weeks, spreads up your legs, comes with numbness or weakness, or if you have diabetes. Go urgently if it started suddenly after an injury, or if you have a wound, color change or swelling. A simple set of blood tests (blood sugar, HbA1c, B12, kidney and thyroid function) finds the cause in many people.

Frequently asked questions

Why do my feet burn at night but not during the day?

Nerve signals feel stronger when you are still and there is nothing else to focus on, and your feet warm up under the covers. Most nerve-related burning follows this pattern.

Is burning feet a sign of diabetes?

It can be. Diabetes is the most common cause of nerve damage in the feet. If you have not had your blood sugar checked recently, ask your doctor for an HbA1c test.

What vitamin deficiency causes burning feet?

Low vitamin B12 is the classic one. Low B1 (thiamine), B6 and folate can also play a role, especially with heavy alcohol use. Note that too much B6 from supplements can also cause nerve symptoms.

Does soaking feet in Epsom salt help burning?

A cool foot soak can be soothing, with or without Epsom salt. There is little evidence that the salt itself helps nerves. Avoid hot water if your feet are numb.
