Itching at Night in Bed

Heat under blankets can intensify an existing itch, while wool, synthetic fibres, dust, or a recently changed detergent may irritate skin. Look for dryness, scale, welts, bites, burrow-like lines, or areas that match contact with the sheet or mattress. Scabies can itch strongly at night and spread among close contacts; bedbugs can cause itchy marks on exposed skin, but marks alone cannot confirm their source. A careful skin and home history is more useful than guessing from one spot.

Keep the room and bedding comfortably cool, wear breathable sleepwear, and wash new linens before use with fragrance-free detergent. Moisturise dry skin after a lukewarm wash and use a cool compress instead of scratching. Inspect seams and mattress edges if bites are suspected, but do not spray chemicals on skin or bedding without following a suitable product’s safety directions. If several people itch, arrange medical advice for the household.

Seek medical review if the itch repeatedly interrupts sleep, causes bleeding or infection, spreads, or remains after bedding and product changes. Get urgent help for breathing difficulty, facial swelling, widespread blistering, fever, rapidly spreading redness, or severe pain. Bring details of new bedding, detergents, travel, pets, and whether anyone else is affected.

Ask whether the marks fit dermatitis, hives, scabies, or another cause; whether household members need assessment; and what treatment is safe for your skin.
