Try the 4-7-8 breath tonight

In through the nose for four, a gentle hold for seven, and a slow sigh out for eight. This Short counts it with you, twice, then lets your breath settle on its own.

Headphones needed. The binaural part works only with headphones: a binaural beat only exists when each ear gets its own tone. On a speaker you will just hear a soft hum. Keep the volume low, and don’t listen while driving.

What it is

A counted round of 4-7-8 breathing, the pattern popularised by Dr Andrew Weil, with a second round at your own pace. The voice counts the first inhale aloud, leaves the seven-count hold as quiet space, then guides a long, soft exhale through the mouth.

How to use it for sleep

Sit or lie comfortably and breathe out fully first. If holding for seven feels like a strain, shorten every count by the same amount, for example 2-3.5-4: it’s the long exhale that matters most, not the exact numbers. Two to four rounds is plenty; stop if you feel light-headed. Our free 4-7-8 breathing pacer shows the rhythm on screen if you want to practise during the day.

Best for

Nights when your heart still feels quick from the day, and anyone who likes a clear, countable exercise rather than an open visualisation.

Sound design note

Under the voice is a soft 3.5 Hz binaural tone (200 Hz left, 203.5 Hz right) with warm brown noise, generated by SleepBetter. 3.5 Hz is in the delta range, but here it is simply a slow, low sound to relax to; research on binaural beats is mixed, and we don’t claim it changes your brain state. Our binaural beats guide explains what the studies found. Headphones needed for the binaural part: a binaural beat only exists when each ear gets its own tone. On a speaker you will just hear a soft hum. Keep the volume low, and don’t listen while driving.

Keep it going

Once the Short ends, you can keep the same calm going without a voice. The binaural beats guide explains how to play a binaural bed safely all night, and the brown noise page covers the warm noise layer on its own, which works on a speaker too. If you want a scene as well, our cabin window rain runs for eight hours with a dark screen.
