Itchy feet at night is one of the most common reasons people lie awake rubbing their soles against the sheets. The reassuring part first: almost every itch gets worse after dark, for ordinary reasons to do with skin temperature, water loss and hormones. The night-time pattern alone is not a warning sign.
What matters is the rest of the picture: whether there is a rash, where it sits, who else in the house is itching, and whether you are pregnant. In this article you’ll learn why itch peaks at night, how to tell the skin causes apart, why scabies is missed so often, when itching points to something in the blood, and which patterns mean you should be seen quickly. The red-flag box lists those that cannot wait.
Why your feet itch more at night
Nocturnal pruritus, meaning itch that worsens in the evening and overnight, is not a separate disease. It is the normal daily rhythm of the skin, and it applies to almost every cause on this page.
What changes in your skin after dark
Several things shift together before sleep. Skin blood flow and skin temperature rise as your core temperature falls, and warm skin itches more than cool skin. Transepidermal water loss, the water that evaporates continuously through the skin, peaks overnight, so the barrier is at its driest and most reactive. Cortisol, the body’s own anti-inflammatory hormone, drops to its daily low in the late evening, and inflammatory signaling in the skin follows the same clock.
Then there is attention. By day, movement and distraction compete for your nervous system’s bandwidth; in a quiet, warm bed the itch signal has the stage to itself. Scratching feels good briefly and then damages the barrier further, which is why the itch-scratch cycle escalates overnight.
Why “worse at night” is reassuring rather than alarming
Because this pattern is built into normal skin biology, it is one of the least useful clues on its own. Two exceptions matter: scabies itch is so much worse at night that it wakes people repeatedly, and the itch of intrahepatic cholestasis of pregnancy is worst at night on the palms and soles.
The common skin causes of itchy feet at night
Most itchy feet have a skin explanation, and most can be narrowed down by where the itch sits and how the skin looks in daylight.
Dry skin and eczema
Dry skin, known medically as xerosis, is the single most common cause, especially in older adults, in winter and in anyone who takes long hot showers. The skin looks dull, faintly scaly, sometimes finely cracked, and the itch peaks after a hot bath and at bedtime.
Eczema, or atopic dermatitis, is the most common inflammatory skin cause of itchy feet and often runs with asthma and hay fever; our overview of eczema as a skin condition covers triggers and flares. If a biopsy report used the phrase spongiotic dermatitis, our companion guide to what spongiotic dermatitis means on a pathology report explains that term; this page stays with the symptom, not the microscope.
Contact dermatitis from shoes, socks and products
Contact dermatitis is inflammation caused by something touching the skin. On feet the usual suspects are rubber accelerators in soles and elastic, chromate in tanned leather, dyes in socks, adhesives in insoles, and the very products people apply to treat the itch. The clue is shape: the rash follows a strap, a seam or the area you rubbed cream into, and stops where the contact stops. Patch testing confirms the trigger. Mite reactions look similar; dermatita produsă de gândacul de covor is regularly mistaken for eczema.
Athlete’s foot, dyshidrotic eczema and psoriasis
Athlete’s foot, or tinea pedis, is a fungal infection that starts in the web spaces between the outer toes, with peeling, softening and splitting, and can spread into a dry scaly pattern across the sole. It is usually itchy and often affects one foot first. Dyshidrotic eczema produces crops of tiny, deep, intensely itchy blisters on the sides of the toes and the arches, often described as tapioca beneath the surface. Psoriasis gives thick, sharply bordered, silvery-scaled plaques, often with nail pitting.
Color change alone has other causes, covered in our guide to red feet, and itch at a nearby site in ankle itch at night. Fungus and eczema are managed in opposite ways, so confirm the diagnosis; a skin scraping takes minutes.
Scabies: the cause that gets missed for months
Scabies is an infestation of the skin by the human itch mite. It belongs here because it is common, it is frequently mistaken for eczema, and the mistake makes it worse: a steroid cream calms the inflammation while the mites keep multiplying, which can lead to the severe crusted form.
Three features separate it from ordinary eczema. First, the itch is intense and characteristically far worse at night, enough to wake people repeatedly rather than merely annoy them. Second, look for burrows: fine, slightly raised, grayish wavy lines a few millimeters long, classically in the finger web spaces, inner wrists and around the waist, and in infants on the palms, soles and ankles. Third, and most telling, others in the household are itching too, because scabies spreads through prolonged skin-to-skin contact.
There is one further trap. After a first infestation, symptoms take roughly four to eight weeks to appear, according to the Centrele pentru Controlul și Prevenirea Bolilor, so people can pass it on before they itch at all.
If this pattern fits, see a doctor rather than treating yourself. Scabies treatments are prescription-only in the United States, and every household member and close contact needs treating at the same time, even without symptoms, or the infestation bounces back. Itching can persist for weeks after successful treatment because it is an allergic reaction to the mite, not proof of failure.
Itching without a rash, and what a blood test can show
If your feet itch but the skin looks normal, or the itch is out of all proportion to a mild rash, the explanation may not be in the skin at all. This is where a blood test earns its place.
Iron, kidney, liver and thyroid
Iron deficiency can cause generalized itch, and is easily missed because iron stores fall long before anemia shows on a blood count; ferritin reveals it, as explained in our guide to feritină scăzută. Chronic kidney disease causes a persistent itch, classically worse at night, often affecting the back, arms and legs as well as the feet; the first tests are covered in niveluri ridicate de BUN și creatinină.
Liver and bile-duct disease causes cholestatic itch, in which components of bile build up in the blood. It is typically worse on the palms and soles, worse at night, and can appear long before any yellowing of the skin. Primary biliary cholangitis is the classic example, and the National Institute of Diabetes and Digestive and Kidney Diseases lists tiredness and itchy skin as its two commonest symptoms; teste ale funcției hepatice with bilirubin are the starting point. Thyroid disease can also cause itch; TSH is the screening test.
Diabetes, blood counts and the rarer causes
Poorly controlled diabetes causes itch three ways at once: dry skin, susceptibility to fungal infection, and nerve damage. Glucoză and HbA1c define it.
A hemoleucograma completă is worth doing for two reasons. It picks up polycythemia vera, a bone-marrow condition with a memorably specific clue: itching that starts within minutes of a hot shower, often described as prickling rather than true itch, on skin that looks entirely normal. The same test reports the eosinophil count, which rises in allergy, drug reactions and parasitic infection. Lymphoma can cause generalized itch, but almost never as itchy feet alone; it comes with drenching night sweats, weight loss or swollen glands.
Itching all over, or itching with nothing to see, is a reasonable trigger for a basic panel rather than another cream.
Nerve-related itch and restless legs syndrome
Nerves can generate itch by themselves, with no rash and nothing to find on the skin. Small-fiber neuropathy and diabetic peripheral neuropathy damage the thin fibers that carry itch, burning and temperature, producing a mixture of tingling, burning, prickling and itch across both feet in a stocking distribution, worse at night and at rest. Numbness in the same area is a strong clue that nerves are involved, as discussed in our article on a numb big toe.
Restless legs syndrome is often confused with itch and is worth separating out. The sensation is a deep urge to move rather than a surface itch; it appears in the evening and at rest, and eases briefly with walking. Scratching does nothing for it. Restless legs is strongly linked to low iron stores in the brain, which is why ferritin is checked even when the blood count looks normal.
Itching in pregnancy: contact your maternity team the same day
This is the most important section on the page. Mild itching is common in pregnancy as the abdomen stretches and the skin dries. One pattern, however, is different, and recognizing it can save a baby’s life.
Intense itching of the palms of the hands and the soles of the feet, worse at night, usually with no rash at all, appearing in the second half of pregnancy, can indicate intrahepatic cholestasis of pregnancy, the most common liver disorder specific to pregnancy. Bile acids accumulate in the mother’s blood, and at higher concentrations this is associated with premature birth and an increased risk of stillbirth. The mother’s symptoms settle after delivery; the risk during pregnancy is to the baby.
Diagnosis is quick: a blood test for serum bile acids with liver function tests. Guidelines are explicit that the bile acid result guides monitoring and the timing of birth, so it needs doing promptly, not at the next routine appointment. Our overview of analize de sânge din timpul sarcinii explains where this fits.
If you are pregnant and your palms and soles itch, particularly at night and particularly with no rash, contact your midwife or maternity unit today. Do not wait to see whether it settles, and do not accept moisturizer as the answer until bile acids have been measured.
How to tell the causes apart, and what helps at home
The table below matches what you notice to what it usually suggests. It is there to shape the conversation with your doctor, not replace it.
| Ce observi | Ce sugerează de obicei | Ce să faci |
|---|---|---|
| Dull, faintly scaly skin, worse in winter and after hot showers | Dry skin (xerosis) | Moisturize regularly and cool your showers; see a doctor if it persists beyond two weeks |
| Itching and peeling between the toes, often one foot first | Athlete’s foot (tinea pedis) | Ask for a skin scraping to confirm fungus before any treatment is chosen |
| Rash shaped like a strap, a seam or the area you rubbed cream into | Dermatită de contact | Stop the suspected product and ask your doctor about patch testing |
| Crops of tiny deep blisters on the sides of the toes and arches | Dyshidrotic eczema | See a doctor; do not guess between eczema and fungal infection |
| Intense night itch that wakes you, and others at home itching too | Scabia | See a doctor promptly; household contacts are treated at the same time |
| Itching all over the body with no rash to see | Posibilă cauză sistemică | Ask about blood tests: blood count, ferritin, kidney, liver, thyroid, glucose |
| Prickling itch within minutes of a hot shower, on normal-looking skin | Possible polycythemia vera | Ask for a full blood count |
| Burning, tingling and numbness across both feet | Nerve-related itch (neuropathy) | Ask about diabetes screening and nerve assessment |
| Itchy palms and soles in the second half of pregnancy, no rash | Possible intrahepatic cholestasis of pregnancy | Contact your maternity team the same day for bile acids and liver tests |
What genuinely helps while you wait
These measures are safe whatever the cause, and none will hide a diagnosis.
- Moisturize consistently: a plain, fragrance-free emollient on clean, dry feet at bedtime.
- Keep the bedroom cool, with lighter bedding. Cooler skin itches less.
- Shorten and cool your showers, because hot water strips the skin barrier.
- Wear breathable cotton socks, alternate your shoes, and dry between the toes.
- Interrupt the scratching: keep nails short and reach for a cool compress.
- Hunt for a contact trigger: new shoes, insoles, detergent or a recent cream.
Deliberately absent from that list is medication advice. Antihistamines, steroid creams, antifungals and scabies treatments all have their place, but which you need depends entirely on the cause, and putting a steroid cream on scabies or a fungal infection makes matters worse. That decision belongs with a clinician who can see your skin.
Când să mergi la medic
Book an appointment if the itch has lasted more than two weeks despite good skin care, if it disturbs your sleep most nights, if it is spreading, or if there is no rash to explain it. Take a daylight photograph; rashes settle in the waiting room.
Red flags: get medical advice urgently
- You are pregnant and your palms and soles itch, especially at night. Contact your midwife or maternity unit today.
- Yellowing of the whites of your eyes or your skin, dark urine, or pale stools.
- Itching all over your body with no rash to explain it.
- Itching with unexplained weight loss, drenching night sweats or swollen glands.
- Itching that wakes you every night while others in your household also itch.
- A foot that turns hot, red, swollen and painful, which can indicate cellulitis.
- Sudden widespread rash with swelling of the lips, face or throat, or difficulty breathing. Treat as an emergency.
Latest scientific advances in understanding nighttime itch
Research since 2023 has sharpened two questions: why itch peaks after dark, and who needs a blood test rather than a cream.
Itch has a measurable daily clock
What was found: investigators at the National Institute of Allergy and Infectious Diseases monitored people with moderate to severe atopic dermatitis around the clock. The chemistry of eczema skin changed in a repeating daily pattern, with the clearest differences shortly after sleep onset, the window in which patients report their worst itching.
What this means for you: the sense that your feet only start itching in bed is not imagination, so describe the pattern out loud rather than assume it will show at a morning appointment.
A rethink of when itch needs a blood test
What was found: a 2024 review in JAMA sorted chronic pruritus, meaning itch lasting six weeks or longer, into inflammatory, nerve-related and mixed types. A minority proved systemic: kidney, liver or thyroid disease, blood disorders, medication or infestation. The authors recommended a basic work-up covering blood count, kidney and liver measures and thyroid function when little is visible on the skin.
What this means for you: if your feet itch and the skin looks normal, asking for blood tests is a mainstream request, not an overreaction.
Scabies is still being recognized late
What was found: a hospital series of infants under two years old with scabies reported that a large proportion had a delayed diagnosis, and that the delay was linked to having been given a different diagnosis first. Family members were the usual source, and lesions clustered on the hands and feet.
What this means for you: if a night-dominant foot itch is not settling with eczema care, and someone else at home is itching, scabies deserves reconsidering.
Bile acid testing now steers decisions in pregnancy itching
What was found: a 2024 national clinical guideline on intrahepatic cholestasis of pregnancy set out how the condition is diagnosed with serum bile acids, and how severity, monitoring and the timing of birth follow from that result. Higher concentrations are associated with preterm birth and stillbirth, and the guideline flags delays in obtaining the test as a problem in themselves.
What this means for you: itching of the palms and soles in later pregnancy is a test-now situation.
Low iron explains more symptoms than most people expect
What was found: a 2025 JAMA review of iron deficiency in adults confirmed that iron stores can be depleted well before anemia appears on a blood count, and listed restless legs syndrome among its recognized symptoms. Diagnosis rests on ferritin or transferrin saturation, not hemoglobin alone.
What this means for you: if your evening foot symptoms feel more like an urge to move your legs than a need to scratch, ferritin is often the most informative single result.
Întrebări frecvente
Why do my feet itch more at night?
Because your skin runs on a daily clock. In the evening, skin blood flow and skin temperature rise while your core temperature drops, water loss through the skin barrier reaches its daily peak, and cortisol, your body’s natural anti-inflammatory hormone, falls to its lowest level. Warmer, drier, less protected skin itches more. On top of that, a quiet bed removes every distraction that competed for your attention during the day. This is why nearly all itch feels worse at night, whatever its cause, and why the night-time pattern alone tells you very little about how serious that cause is.
Can itchy feet mean liver problems?
Sometimes, but it is not the usual explanation, and itchy feet on their own rarely point that way. Liver and bile-duct disease can cause cholestatic itch, in which components of bile build up in the blood. It classically affects the palms and soles, is worse at night, and can appear before any yellowing of the skin. What makes it more likely is itching that is generalized rather than confined to the feet, itching with no rash, or itching alongside dark urine, pale stools, fatigue or yellow eyes. A set of liver function tests answers the question quickly.
How do I know if it is scabies?
The strongest clues are the intensity and the company. Scabies itch is severe enough to wake you repeatedly, it is markedly worse at night, and other people you live with usually start itching within a few weeks. Look for fine, wavy, slightly raised burrows a few millimeters long in the finger web spaces, the inner wrists and around the waist; in babies and toddlers the palms, soles and ankles are typical. A doctor confirms it by finding the mite, its eggs or its droppings under a microscope. Do not try to treat it yourself: effective products require a prescription, and everyone in the household needs treating at the same time.
Why are my hands and feet both itchy at night?
Itch affecting the palms and soles together is a pattern worth taking seriously, because it is less typical of ordinary dry skin. In pregnancy it raises the possibility of intrahepatic cholestasis and warrants a same-day call to your maternity team. Outside pregnancy, the common causes are dyshidrotic eczema, which produces tiny deep blisters, contact dermatitis from something handled or worn, and cholestatic itch from liver or bile-duct disease. Scabies also favors the hands. Because the list includes both harmless and important causes, palm-and-sole itch lasting more than a week or two is worth having assessed.
Can itchy feet be a sign of diabetes?
They can, in three different ways. High blood sugar dries the skin out, which itches. It also makes fungal infections of the feet and nails more likely and harder to clear. And over time it damages the small nerve fibers in the feet, producing a mix of burning, tingling, numbness and itch that is typically worse at night and at rest. Persistent foot itching accompanied by numbness, increased thirst, frequent urination or slow-healing skin is a reasonable prompt to have blood glucose and HbA1c checked. Diabetes is not the commonest cause of itchy feet, but it is one of the easiest to test for.
Does itching at night mean I have a fungal infection?
Not necessarily. Athlete’s foot is a frequent cause of itchy feet, but it usually leaves visible signs: peeling, cracking or softening between the outer toes, or dry scaling across the sole, often on one foot before the other. If your skin looks normal, if the itch is spread over the whole foot rather than concentrated between the toes, or if it is part of a wider itch involving other parts of the body, fungus becomes less likely. Guessing is a real risk here, because antifungal and anti-inflammatory treatments are not interchangeable. A quick skin scraping settles the question.

If your itch has no rash to explain it, the answer often sits in a blood test rather than on your skin: a full blood count, ferritin, liver and kidney tests, thyroid function and glucose. AI DiagMe turns those numbers into plain language so you can see what is normal, what is not, and what is worth raising with your doctor. It helps you understand results; it does not diagnose, and it cannot see a rash or examine your feet.
