4-7-8 Breathing: How the Technique Works and What It Can Do

In 4-7-8 breathing you breathe in through your nose for 4 seconds, hold for 7 and breathe out through your mouth for 8. Beginners usually do four rounds once or twice a day or at bedtime. It can help you wind down, but it is not a treatment for insomnia or anxiety disorders.

How to do 4-7-8 breathing

Sit upright or lie comfortably in bed. Rest the tip of your tongue just behind your upper front teeth and keep it there for the whole exercise. Count at an even pace; the ratio of 4 to 7 to 8 matters more than exact seconds.

  1. Breathe out fully through your mouth with a soft whoosh.
  2. Close your mouth and breathe in quietly through your nose for a count of 4.
  3. Hold your breath for a count of 7.
  4. Breathe out audibly through your mouth for a count of 8.
  5. That is one breath. Do three more, four rounds in total.

If 4-7-8 feels too long, change the pace

Many people cannot hold for 7 seconds at first. Count faster and keep the ratio. Mild light-headedness is common in the first sessions and usually fades with practice. If you feel clearly unwell, stop and breathe normally.

Other patterns skip the long hold altogether. What most have in common is an exhale that is as long as or longer than the inhale.

4-7-8 breathing or box breathing?

Both slow your breathing down, but the emphasis differs. 4-7-8 breathing stresses a long exhale and suits quiet moments lying down. Box breathing, with four equal phases, is easier to remember, can be done discreetly while seated and is often suggested before stressful situations.

Try each for a few days. What counts most is practising regularly, including when you are not stressed, so the technique comes easily when you need it.

What the research shows

Slow, paced breathing is well studied, 4-7-8 breathing specifically much less so. A 2023 randomised trial from Stanford University compared five minutes of daily breathwork with mindfulness meditation over one month. Breathwork, especially cyclic sighing with its long exhale, improved mood more and lowered breathing rate. Box breathing was one of the tested techniques; 4-7-8 was not.

None of these techniques is a guaranteed route to sleep or a substitute for treatment. If you have ongoing sleep problems, panic attacks or a lung condition, talk to your doctor.

Safety

Breath-hold exercises are generally fine for healthy adults who are sitting or lying down. A few rules always apply.

  • Never practise while driving or operating machinery.
  • Never hold your breath in or near water: fast breathing beforehand and long holds can cause sudden blackout.
  • Stop and breathe normally if you feel dizzy, tingly or short of breath.
  • If you are pregnant or have a heart or lung condition, ask your doctor first.

What the app cannot do

Slowtide is not a medical device and does not replace medical advice. It paces your breathing but does not measure it.

Price

Every classic technique is free for good; Pro, with breath-hold tables, programs and unlimited custom patterns, is a monthly or yearly subscription. We build this app ourselves; on Google Play it is listed under the developer name InfinityAkhi.

Frequently asked questions

How often should I do 4-7-8 breathing?

Four rounds once or twice a day is a common starting point. Doing it regularly matters more than the time of day.

Does 4-7-8 breathing help you fall asleep?

Many people find it calming, and a calmer mind makes sleep easier. There is little research on 4-7-8 and sleep specifically, so it is not a guarantee.

Why do I feel dizzy doing it?

Breathing unusually slowly and holding often causes mild light-headedness at first. Count faster or do fewer rounds, and stop if you feel clearly unwell.

How is it different from box breathing?

Box breathing uses four equal phases (4-4-4-4); 4-7-8 breathing uses a long hold and an even longer exhale.
