What causes itchy skin at night?
Night amplifies itch: the body warms under blankets, cortisol dips, distraction disappears, and dry indoor air pulls moisture from skin. Simple dryness is the leading cause, especially after hot showers and soapy scrubbing.
Moisturize while skin is still damp, keep showers shorter and cooler, and switch to fragrance-free everything for two weeks; most night itch surrenders to that alone.
Itch all over without any rash that persists for weeks deserves blood tests, since iron deficiency, thyroid, liver and kidney conditions can itch. New severe night itch in a household, especially with tiny burrow lines between fingers, means checking for scabies.

For dry or itchy skin
Doctors reach for plain, fragrance-free creams like CeraVe or Cetaphil, not fancy actives. A thicker cream beats lotion, applied within minutes of washing while skin is still damp.
