Mentis- Breathe in through your nose for 4, hold for 7, breathe out through your mouth for 8.
- Start with 4 rounds (about 75 seconds). It's most useful in bed or when you wake at night.
- The long exhale is the active ingredient. Slow, extended exhaling is linked with a calmer heart rhythm.
How to do 4-7-8 breathing
- Get comfortable. Lie on your back or sit with your shoulders loose. Rest the tip of your tongue just behind your top front teeth if you like; it's part of the traditional method but optional.
- Empty out first. Breathe out fully through your mouth.
- In for 4. Close your mouth and breathe in quietly through your nose.
- Hold for 7. Softly. No straining.
- Out for 8. Breathe out slowly through your mouth, as if blowing on hot chai.
- Repeat for four rounds, then let your breathing go back to normal and notice how your body feels.
Does 4-7-8 breathing really help you sleep?
It helps many people wind down, and the reason is the exhale. Breathing out activates the parasympathetic nervous system, the branch that slows your heart. Making the exhale twice as long as the inhale tips the balance towards calm. Reviews of slow-breathing research link it with higher heart rate variability and lower reported anxiety (Zaccaro et al., 2018). A small 2022 study of 4-7-8 breathing in healthy young adults reported improvements in heart rate variability after the practice (Vierra et al., 2022).
Be honest with yourself about what it does: it settles your body so sleep can come. It isn't an off switch. The habits with the strongest evidence for better sleep are the ones in cognitive behavioural therapy for insomnia (CBT-I): a fixed wake time, only going to bed when sleepy, and getting up when you can't sleep. In a meta-analysis of CBT-I trials, people fell asleep about 19 minutes faster and spent about 26 minutes less lying awake in the night (Trauer et al., 2015). Use 4-7-8 as part of that, not instead of it.
When to use 4-7-8 breathing
- Lights out, once the phone is face down. Four rounds, then let your breathing find its own pace.
- When you wake at 3am and the mind starts its list. Don't check the time; breathe first. Our guide to sleep explains why the clock makes it worse.
- Before an exam or interview, when your heart is already running ahead of you.
- After a fight or a bad call, before you type the reply.
4-7-8 in the Mentis Sleep plan
The Mentis Sleep plan pairs slow breathing with the habits that move sleep most: "A time I wake up", "The hour before bed", "Bed means sleep" and "The 3am mind". Guided activities like "Hand On Belly, Three Slow Breaths", "Winding Down, Guided" and "Back To Sleep After Being Woken" are practised in the daytime first, so they're already familiar when you need them at night. Pick your wake time with the sleep calculator, then let 4-7-8 help you land.
Frequently asked questions
How many times should I do 4-7-8 breathing?
Start with four rounds, which take about 75 seconds. Once that feels comfortable you can go up to eight. More isn't better; the aim is to slow down, not to push.
Does 4-7-8 breathing help you fall asleep?
Many people find it helps them wind down. A long, slow exhale is linked with a calmer heart rhythm, and counting gives a busy mind something to hold. It works best alongside the basics that matter most for sleep: a fixed wake time and a calm last hour before bed.
Who created the 4-7-8 breathing method?
The 4-7-8 pattern was popularised by the American physician Dr Andrew Weil, who adapted it from pranayama, the breath practices of yoga.
Is 4-7-8 breathing the same as pranayama?
It's closely related. Like many pranayama practices, it slows the breath and lengthens the exhale. It's simpler than most and needs no training: just the count.
I can't hold my breath for 7 seconds. Is that okay?
Yes. Keep the ratio but speed up the count: 2-3.5-4 or 3-5-6. The ratio matters more than the exact seconds. Stop if you feel light-headed.
