4-7-8 vs Coherent Breathing: Which One Should You Use?
Two of the most popular breathing techniques in the world are 4-7-8 Breathing and Coherent Breathing — and people often ask me which one they should use. Here’s the short answer:
Use 4-7-8 Breathing when you need to power down quickly — especially for falling asleep or calming intense anxiety. Use Coherent Breathing as your steady daily practice for long-term calm, focus and heart health. One is a reset button; the other is a rhythm to live by. And happily, you don’t have to choose — they make a lovely team. :)
Let me explain both, and then how to decide (this post is adapted from my new book, Breathing Exercises for Dummies).
What is 4-7-8 Breathing?
Don’t worry — 4-7-8 isn’t your locker combination! It’s one of the most popular breathing exercises you’ll find, with roots in ancient yoga practice and popularised by Dr. Andrew Weil.
The numbers stand for the counts: inhale for four, hold for seven, exhale for eight. That long exhale (and the hold before it) stimulates your vagus nerve — a major nerve that tells your body it’s safe to relax. Your heart rate drops, your blood pressure eases, and because you’re busy counting, your mind has less room to spiral into anxious thoughts. It’s often described as a “natural tranquiliser” for your nervous system — a one-two combination of physical and mental calm.
How to do it:
- Sit up straight or lie down (in bed is perfect); relax your shoulders.
- Exhale fully through your mouth with a gentle whoosh.
- Close your mouth and inhale quietly through your nose for a count of four, filling your belly rather than your chest.
- Hold your breath for a count of seven, keeping your face and jaw relaxed.
- Exhale slowly through your mouth for a count of eight — imagine making a candle flame flicker, not blowing it out.
- Repeat for about four cycles when you’re starting out, then breathe normally.
A little tip from the book: those are counts, not necessarily seconds. If seven feels like an eternity, try a gentler 3-5-6 or even 2-4-4 — what matters is the pattern, with the exhale longest. And keep it to a few cycles at first; too many in a row can make you lightheaded.
What is Coherent Breathing?
Coherent Breathing is my personal favourite of all the breathing exercises — if I could only recommend one technique for a healthier, happier and perhaps even longer life, this would be it.
It’s beautifully simple: breathe gently in through your nose for about five seconds, and out for about five seconds — roughly five to six breaths per minute, with no pauses, one breath flowing into the next. The word coherent means forming a unified whole, and that’s exactly what happens: your heart, lungs and brain begin to sync up, like the notes of a piece of music coming into harmony.
Breathing at this slow, even rhythm raises your heart-rate variability (HRV) — a key marker of resilience — and research links regular practice with reduced stress and anxiety, better cardiovascular function, clearer thinking, improved sleep and steadier emotions. Fascinatingly, ancient traditions found this rhythm long before the scientists did: Gregorian chants and yogic pranayama practices naturally settle people at around six breaths per minute.
How to do it:
- Sit comfortably, relax your shoulders, and unclench your jaw.
- Breathe in gently through your nose for about five seconds — belly rising, nothing forced.
- Breathe out through your nose for about five seconds, just as smooth and steady.
- Continue, with no pauses between breaths, for five minutes to start with.
I like to imagine a smooth sine wave — breathing up the wave on the inhale, down the wave on the exhale. If five seconds feels too slow at first, begin with three or four seconds each way and build up gently. Everyone has a slightly different sweet spot, usually somewhere between four-and-a-half and seven breaths per minute.
The key differences at a glance
| 4-7-8 Breathing | Coherent Breathing | |
|---|---|---|
| Best for | Falling asleep, calming acute anxiety | Daily calm, focus, heart health, resilience |
| Speed of effect | Fast — a few cycles | Gentle — builds within minutes, compounds over weeks |
| Pattern | Uneven: in 4, hold 7, out 8 | Even: in ~5, out ~5, no holds |
| Session length | Short — about four cycles | 5–20 minutes, ideally daily |
| Feel | A deliberate “power-down” switch | A soothing rhythm you can settle into |
| When I use it | In bed, or in a stressful moment | Most days, as a steady practice |
Which should you choose?
- For sleep: 4-7-8 is the classic choice — do your four cycles in bed, then let yourself drift. If racing thoughts are the real culprit, a few minutes of Coherent Breathing first makes a lovely wind-down. (More night-time help in my deep sleep meditations.)
- For sudden stress or anxiety: 4-7-8 acts fast. Coherent Breathing also works wonderfully here if breath-holding feels uncomfortable when you’re anxious.
- For focus and everyday balance: Coherent Breathing, hands down. Even five minutes a day makes a noticeable difference after a couple of weeks — and up to 20 minutes twice a day if you fall in love with it, as some people do.
- For building a lasting practice: Coherent Breathing is the rhythm to build your life around, with 4-7-8 in your back pocket for the moments you need a stronger reset.
And if you’re wondering how these two compare with the famous square-shaped technique, I’ve written a whole post on Box Breathing vs 4-7-8 Breathing — plus a complete guide to Box Breathing.
Can you do both?
Absolutely — and I’d encourage it. Think of Coherent Breathing as your daily nourishment and 4-7-8 as your emergency kit. A pattern I love: five minutes of Coherent Breathing during the day (on the train, between meetings, with a cup of tea), and four cycles of 4-7-8 when your head hits the pillow. Your nervous system learns both cues, and each gets more effective with practice.
Common questions
Is 4-7-8 breathing safe? For most people, yes — it’s simply slow breathing. The main thing is not to overdo it: stick to a few cycles at first, as long holds can make you lightheaded. If you’re pregnant or have a heart or respiratory condition, keep the counts gentle and check with your doctor. And never practise breath-holds while driving or in water.
Why do I feel dizzy doing 4-7-8? You’re probably pushing the counts too hard, too soon. Shorten the pattern (try 3-5-6), breathe more gently, and build up over days and weeks. Straining defeats the purpose — relaxed is the whole point.
How long until Coherent Breathing works? You’ll usually feel calmer within a few minutes of a session. The deeper benefits — steadier mood, better sleep, higher HRV — build with consistent daily practice over two to three weeks.
Do the counts have to be exact seconds? No. In both techniques, the counts are a guide, not a stopwatch. Find the pace that feels calming and unforced for you — that’s the one that works.
If you’d like me to guide you through these rather than counting alone, both feature in my book’s audio tracks — and I teach breathing practices like these regularly in the Daily Mindfulness Club. There’s a free 4-7-8 Breathing exercise below to try right now for free.
