4-7-8 Breathing: A Complete Guide

Inhale for 4. Hold for 7. Exhale for 8.

4-7-8 breathing is a paced-breathing pattern popularized by Dr. Andrew Weil, with roots in pranayama — the breath-regulation practices of yoga. Its defining feature is an exhale that's twice as long as the inhale, with a long hold in between.

What 4-7-8 breathing is

One cycle has three phases:

1. Inhale quietly through the nose for a count of 4
2. Hold the breath for a count of 7
3. Exhale completely through the mouth — often with a soft whoosh — for a count of 8

A full cycle takes 19 counts, far slower than everyday breathing. Compared with box breathing's even square, 4-7-8 is deliberately lopsided: the long exhale is the point.

Why the long exhale

The whole pattern runs slow, and most of each cycle is spent holding or breathing out. Slow breathing has been studied for decades, much of it in research on heart-rate variability (Lehrer & Gevirtz 2014; Russo et al. 2017; Zaccaro et al. 2018). The 7-count hold comes from the tradition: it gives the pattern its rhythm and makes room for the long exhale without rushing.

How to do it, step by step

1. Sit with your back reasonably straight, or lie down if you're using it before sleep.
2. Rest the tip of your tongue against the ridge behind your upper front teeth (the traditional form — optional, but part of the original technique).
3. Exhale completely through your mouth first, with a whoosh.
4. Inhale quietly through your nose for a count of 4.
5. Hold for a count of 7.
6. Exhale audibly through your mouth for a count of 8.
7. Repeat for up to 4 cycles when starting out. The counts can be brisk at first — the ratio (4:7:8) matters more than the absolute speed. Slow the counting down as it gets comfortable.

If the 7-count hold feels like too much, shorten everything proportionally — 3-5-6, or even 2-3-4 — and keep the shape.

When people reach for it

The long exhale gives 4-7-8 a distinctly winding-down character:

• Before bed, as part of a wind-down routine
• Back in bed after a 3am wake-up
• After putting the phone down for the night
• On a long flight, seat reclined as far as it goes
• In the quiet after a full-tilt day

Safety note

Stop and breathe normally if you feel dizzy, lightheaded, or short of breath — the long hold makes this more common with 4-7-8 than with gentler patterns. Skip the breath-holds — or check with your doctor first — if you're pregnant or have a heart condition, blood pressure concerns, or a respiratory condition such as asthma or COPD. Breathing exercises are a wellness practice, not medical care.
