What it is

The 4-7-8 pattern is deliberately lopsided: inhale for four, hold for seven, exhale for eight. The exhale is twice the length of the inhale, and that ratio is the point — a long, slow out-breath is the part of the cycle most associated with the body shifting out of alert readiness.

The pattern was popularised in the West by Dr Andrew Weil, who drew it from pranayama practice. It is most often taught as a technique for falling asleep, though nothing restricts it to bedtime.

A natural tranquilizer for the nervous system — ideal for winding down before sleep.

How to do it

  1. Rest the tip of your tongue on the ridge behind your upper front teeth.
  2. Exhale completely through your mouth, then gently close it.
  3. Inhale quietly through your nose for a count of 4.
  4. Hold your breath for a count of 7.
  5. Exhale fully through your mouth for a count of 8, then repeat.

When to use it

  • Lying in bed with a mind that will not stop. Four rounds is the usual instruction.
  • After an argument, bad news, or anything that has left you activated and unable to settle.
  • As a way down from intense exercise or a long day, when you want the body to register that the demand is over.

Before you start

  • The seven-count hold is the hardest part for beginners. If it makes you tense, halve every number — 2-3.5-4 keeps the ratio and removes the strain.
  • Lightheadedness means you are working too hard. Stop, breathe normally, and use shorter counts next time.
  • Practise sitting or lying down, never while driving or in water.
  • If you are pregnant, or have a cardiovascular, respiratory, or seizure condition, check with your clinician before practising breath retention.

Common questions

Does 4-7-8 breathing actually help you fall asleep?
Many people find it helps them settle, and extending the exhale relative to the inhale is a well-established way of encouraging the body to stand down from an alert state. It is a useful tool rather than a treatment — if you have persistent insomnia, that is worth raising with a clinician.
How many rounds of 4-7-8 should I do?
Four rounds is the standard instruction, and it is common advice to build up slowly rather than starting with long sessions. If four rounds leaves you comfortable, there is no harm in a few more.
Do I have to exhale through my mouth?
It is usually taught with a mouth exhale, often with a soft audible sound, which makes it easier to keep the out-breath slow and complete. If that feels awkward, a nasal exhale of the same length works.
What if the 7-count hold is too long?
Scale everything down and keep the proportions: 2-3.5-4 is the same technique at half the size. The 4:7:8 ratio matters more than the absolute seconds.
