Why it helps: pink noise is warm and even - the rush of steady rain rather than a bright hiss. It's easy to listen to for hours, and several small studies link it to more time in deep, slow-wave sleep.

Why pink noise for sleep

Pink noise softens the high frequencies that make white noise sound bright, giving a natural, rain-like tone many people find especially restful. It masks the room while feeling gentle enough to fall asleep to.

What the research says

Small studies have associated steady pink noise during sleep with increased slow-wave (deep) sleep and, in some, better next-day memory. The science is early and individual results vary - but pink noise is pleasant and harmless to try.

Set a fade timer

Let it fade out gently after you fall asleep.

Layer with rain

Pink noise under rain is a cosy, natural bedtime set.

Keep it soft

A moderate volume masks the room without intruding.
