4-7-8 breathing
The 4-7-8 method — popularised by Dr Andrew Weil — is a relaxing breath built around a long, slow exhale. You breathe in for 4 seconds, hold for 7, and exhale for 8. That extended out-breath is the active ingredient: it nudges your nervous system toward its calming, rest-and-digest mode, which is why people reach for it to fall asleep or to settle a racing mind.

- Best for
- Calm down
Also known as relaxing breath, 4 7 8 technique.
How to do it
- 1Sit or lie somewhere comfortable and rest the tip of your tongue just behind your top front teeth.
- 2Empty your lungs with a gentle exhale.
- 3Breathe in quietly through your nose for a count of 4.
- 4Hold your breath for a count of 7.
- 5Exhale completely through your mouth for a count of 8, making a soft whoosh.
- 6That is one round. Start with four rounds and build up as it becomes comfortable.
What it's good for
- A reliable pre-sleep wind-down you can do in bed.
- Fast way to interrupt anxious or racing thoughts.
- The long exhale gently shifts you toward parasympathetic (calming) tone.
The evidence. Slow breathing with a prolonged exhale has good evidence for raising heart-rate variability and easing acute stress; the specific 4-7-8 count is a practical convention rather than a uniquely proven formula.
Safety
- The long hold can feel like a lot at first — shorten it or stop if you feel lightheaded.
- Keep the ratio, not the exact seconds: scale down to 2-3.5-4 if 4-7-8 is a stretch.
Frequently asked questions
Is 4-7-8 breathing good for sleep?
- It's one of the most popular pre-sleep techniques because the long 8-second exhale helps switch on your body's calming response. Do a few rounds lying in bed; many people find it shortens the time it takes to drift off.
How many rounds of 4-7-8 should I do?
- Start with four rounds. Once that feels easy you can work up to eight, but there's no need to push — stop if you feel any dizziness.
What if holding for 7 seconds is too hard?
- Keep the 4:7:8 ratio but shrink the unit, e.g. 2-3.5-4 seconds. The relaxing effect comes from the exhale being longer than the inhale, not from the exact numbers.
