What should you know about winter itchy skin?

Cold air, indoor heating, long hot showers, and fragranced cleansers can remove surface oils and increase water loss. The skin may feel tight, rough, flaky, or cracked, with itch often strongest on the legs, arms, and sides of the body. Asteatotic eczema, sometimes called winter itch, can produce fine cracks in a dry, patterned rash. Eczema, contact irritation, psoriasis, and other conditions can look similar, so a persistent or localised rash should not be assumed to be weather-related.

Notice when itching began, which products touch the area, whether the skin is cracked or weeping, and whether anyone else at home is itchy. These details help guide assessment.

Keep showers brief and lukewarm, use a fragrance-free cleanser only where needed, and pat rather than rub the skin dry. Apply a thick emollient while the skin is still slightly damp, then repeat whenever tightness returns. Wear soft breathable layers and keep nails short to reduce damage from scratching. A clinician may recommend topical corticosteroids for an inflamed eczema flare, with instructions on where and how long to apply them.

Seek medical advice if itch lasts despite regular moisturising, disturbs sleep, or comes with a spreading rash, swelling, severe cracks, or recurrent flares. Prompt care is needed for warmth, pus, honey-coloured crusts, fever, facial swelling, or breathing symptoms. Widespread itch without an obvious rash, or itch beginning after a new medicine, also deserves assessment.

Does this look like dry skin, asteatotic eczema, or another rash? Which emollient texture should I use? Should I avoid a particular cleanser or fabric? If a topical corticosteroid is needed, where should it go and for how long? What signs suggest infection?
