What is 4-7-8 breathing?
4-7-8 is a slow-breathing exercise with a long, unhurried out-breath. It grew out of yogic breathing practices and became popular as a simple way to wind down — before sleep or in a tense moment. The counts describe the ratio between the phases, so you can adapt the pace to your own lungs.
How to do it, step by step
- Sit comfortably, back upright, shoulders relaxed. You can also lie down.
- Breathe out fully through your mouth.
- Breathe in quietly through your nose while counting to 4.
- Hold your breath while counting to 7.
- Breathe out slowly through your mouth while counting to 8.
- That is one round. Start with 4 rounds; with practice you can do up to 8.
How many rounds, how long, how often
Start with 4 rounds — at the counts above that is a little over a minute. You can practise once or twice a day, for example in the evening, and whenever you want to slow down. With practice you can build up to 8 rounds. If the hold feels too long, slow the count down or switch to 4-4-6; there is nothing to gain from forcing it.
4-7-8 breathing before sleep
4-7-8 is popular as part of a wind-down routine: lights low, phone away, a few rounds lying in bed. Slow breathing can help you shift from “busy” to “calm” — it is not a cure for sleep problems. If you regularly struggle to sleep for several weeks, talk to your GP.
4-7-8 vs box breathing
Both slow your breathing down. 4-7-8 has a long hold and an even longer out-breath; box breathing (4-4-4-4) keeps all four phases equal, which some people find easier to follow. Try both in the timer above and keep the one that feels comfortable.
Gentler rhythms
The long hold in 4-7-8 is not for everyone. These rhythms work on the same principle — slower breathing with a longer out-breath — and you can switch between them in the timer above.
| Rhythm | In · hold · out | Good for |
|---|---|---|
| 4-7-8 | 4 · 7 · 8 | people who are comfortable holding their breath |
| 4-4-6 | 4 · 4 · 6 | starting out, or during the day |
| Box | 4 · 4 · 4 · 4 (pause after breathing out) | people who like an even count |
What research says
A systematic review of studies on slow breathing — around six breaths a minute — links it with higher heart rate variability and with people feeling calmer and more relaxed (Zaccaro et al., 2018). In a randomised study, five minutes of daily structured breathing improved mood over a month; a breathing pattern with a long exhale did best (Balban et al., 2023).
Research on the 4-7-8 rhythm itself is limited and the studies are small (for example, Vierra et al., 2022). The honest conclusion: it is a useful self-regulation skill, not a cure.
When to be careful
- If you feel dizzy or your fingers tingle, stop and breathe normally.
- If you have a heart or lung condition, or are pregnant, ask your doctor about breath-holding first; 4-4-6 is the gentler option.
- Don’t practise while driving or whenever you need your full attention.
Breathing with Aura
In psyarea, breathing exercises sit next to your conversations with Aura: after a tense talk, Aura can suggest a few rounds, and the sphere guides the rhythm so you don’t have to count. psyarea is an experimental wellbeing tool for adults and is currently preparing its beta.
When to talk to a professional
Self-help exercises are for everyday ups and downs. If low mood, worry or sleeplessness lasts for more than two weeks, gets in the way of work or relationships, or frightens you, talk to your GP or a licensed mental health professional. If you think about harming yourself, call 112 or a crisis line now.
