Why Is My Skin Itchy at Night? 8 Causes and How to Stop Night-Time Itching
Itchy skin guide
Part of our Itchy skin guide · Eczema guide
Skin often itches more at night because it gets warmer, loses more water through its barrier and the body's natural anti-inflammatory hormone, cortisol, drops to its lowest level. The most common causes are dry skin and eczema, but scabies, bed bugs, hives and internal conditions can also cause night-time itch. A lukewarm shower, a thick moisturiser, a cool bedroom and a cooling anti-itch cream relieve most cases.
- Night itch is linked to the body's daily rhythms: warmer skin, more water loss and lower cortisol at night.
- Dry skin and eczema are the most common causes; scabies classically itches worst at night.
- Sleep disturbance in adults with eczema rises with severity and is driven mainly by itch.
- A bedtime routine of lukewarm bathing, moisturiser, a cool room and cooling creams helps most people.
- Itch all over without a rash, or with weight loss or night sweats, should be checked by a doctor.
Why does itching get worse at night?
Night-time itch is a recognised feature of many skin and medical conditions, and researchers believe several of the body's daily rhythms combine to cause it (Patel et al., 2007):
- Skin gets warmer at night. Blood flow to the skin increases in the evening, and warmth makes itch nerves more active.
- The skin barrier leaks more water. Water loss through the skin is higher in the evening, so dry skin feels drier and itchier.
- Natural anti-inflammatory hormones dip. Cortisol, the body's own anti-inflammatory hormone, is at its lowest around midnight.
- Fewer distractions. In a quiet, dark room the brain pays more attention to itch signals.
The result is the familiar pattern of scratching in bed, broken sleep and more itch the next day.
What causes itchy skin at night?
| Cause | Clues | What helps |
|---|---|---|
| Dry skin (xerosis) | Itchy legs and arms, worse in winter and after hot showers; no obvious rash | Lukewarm showers and a thick moisturiser at bedtime. See winter itch |
| Eczema (atopic dermatitis) | Dry, red patches in elbow and knee creases, neck or hands; history of eczema, asthma or hay fever | Barrier care plus anti-inflammatory treatment. See types of eczema |
| Scabies | Intense itch that is worst at night, tiny bumps or lines between fingers, on wrists or waist; others at home itch too | Needs prescription treatment for everyone in the household (DermNet) |
| Bed bugs or dust mites | New bites in lines or clusters after sleeping; itch near bedding | Inspect the mattress seams, wash bedding hot |
| Hives | Raised welts that move around within hours | Antihistamines; see hives and itch |
| Psoriasis | Well-defined, thick plaques with silvery scale, often on elbows, knees and scalp | See eczema vs psoriasis |
| Neurodermatitis | One or two thick, leathery patches you scratch out of habit, especially in the evening | Break the itch-scratch cycle; see neurodermatitis |
| Internal causes | Itch all over without a rash; tiredness, weight loss, night sweats, yellow skin or kidney disease | Blood tests with a doctor: liver, kidney, thyroid, iron and blood count |
Why does eczema itch so much at night?
Night itch is one of the hardest parts of eczema. A systematic review found that sleep disturbance is common in adults with eczema, becomes more likely as eczema gets more severe, and is driven largely by itch and scratching (Jeon et al., 2017). Getting the eczema itself under better control is the most reliable way to sleep better, so if your eczema keeps you awake most nights, ask your doctor to review your treatment.

How do you stop itching at night?
- Take a short, lukewarm bath or shower before bed, then pat dry.
- Moisturise within 3 minutes with a thick, fragrance-free cream or ointment. In a Cochrane review, regular moisturisers reduced eczema flares and the amount of steroid cream needed (van Zuuren et al., 2017).
- Cool the bedroom to about 18 to 20°C (64 to 68°F) and use light, breathable cotton bedding.
- Apply a cooling anti-itch cream to itchy patches. Menthol acts on the skin's cold receptor; in a real-life study, a cream with a menthol-like cooling agent reduced itch in people with eczema (Misery et al., 2019).
- Keep nails short and consider cotton gloves if you scratch in your sleep.
- Swap scratching for pressing or tapping, or hold a cool, damp cloth on the spot. Habit-reversal techniques help break the itch-scratch cycle.
- Avoid alcohol, hot drinks and wool close to bedtime, all of which can make skin warmer and itchier.
- Ask about antihistamines if hives are the cause. For eczema, they mainly help by making you drowsy rather than by stopping the itch.
How does Traditional Chinese Medicine explain itching at night?
In Traditional Chinese Medicine, itch that is worse at night is often linked with Blood Dryness or Yin deficiency, when the skin is not properly nourished and moistened, especially in older adults and long-standing eczema. Itch that comes in sudden waves is linked with Wind. Treatment aims to moisten and nourish the skin while calming Wind, using gentle, cooling external herbs such as Ku Shen and She Chuang Zi together with rich bases.

When should you see a doctor about itching at night?
- The itch lasts more than 2 weeks despite good skin care, or keeps you awake most nights.
- You itch all over without a visible rash.
- You also have weight loss, fever, night sweats, tiredness, yellow skin or eyes, or swollen glands.
- Other people in your home are itchy too (possible scabies).
- The skin is broken, weeping or infected from scratching.
Persistent itch without a rash, particularly in older adults, can be linked to conditions such as liver or kidney disease, thyroid problems or iron deficiency, so it deserves a check-up (Fourzali and Yosipovitch, 2019).

Frequently asked questions
Why does my skin itch more at night?
At night skin gets warmer, loses more water and the body's natural anti-inflammatory hormone cortisol is at its lowest, which together make itch nerves more active. There are also fewer distractions, so you notice the itch more.
How do I stop itching at night fast?
Hold a cool, damp cloth on the area, then apply a thick moisturiser and a cooling anti-itch cream with menthol. Keep the bedroom cool and nails short so scratching does less damage.
Can itching at night be a sign of something serious?
Usually it is dry skin or eczema. See a doctor if you itch all over without a rash, or if itch comes with weight loss, fever, night sweats, tiredness or yellow skin, as these can point to an internal cause.
Is itching at night a sign of scabies?
Intense itch that is worst at night, with tiny bumps between the fingers, on the wrists or waist, and other people at home itching too, suggests scabies. It needs prescription treatment for the whole household.
What is the best cream for itchy skin at night?
A thick, fragrance-free moisturiser is the foundation. For itchy patches, a steroid-free cream with cooling menthol or borneol gives quick relief, and eczema flares may need a prescription cream from your doctor.
