How to Do 4-7-8 Breathing: A Step-by-Step Guide for Sleep and Calm

4-7-8 breathing is a simple pattern: you inhale for 4 seconds, hold for 7 seconds, and exhale slowly for 8 seconds. Alongside box breathing, it is one of the most well-known breathing techniques around, and for good reason.

Done correctly, it is one of the most effective tools for winding down after a stressful day or settling the mind before sleep. This guide walks through the pattern step by step, how to modify it if the hold feels like too much, why the long exhale does real work, and when to practise it for the best effect.

What is 4-7-8 breathing?

4-7-8 breathing, sometimes called the “relaxing breath,” was popularised by integrative medicine physician Dr. Andrew Weil, drawing on the ancient yogic practice of pranayama. The pattern is simple: inhale for 4 seconds, hold for 7 seconds, exhale for 8 seconds.

How to modify it if it feels like too much

The 7-second hold on top of an 8-second exhale can feel intense, especially early on. There is no need to force it:

• Standard: 4 seconds in, 7 seconds hold, 8 seconds out
• A bit easier: 4 seconds in, 8 seconds out, no hold
• Easier still: 4 seconds in, 6 seconds out, no hold

You can add a small hold at the top once you are comfortable. Start slow and build from there. There is no rush to get to the full ratio.

How to do it, step by step

Place your left hand on your lowest left rib and your right hand on your lowest right rib, fingers tucked around toward your back so you are holding your whole waistline.

1. Inhale slowly and fully for 4 seconds. Focus on your ribs expanding out into your hands.
2. Hold for 7 seconds (or your modified count).
3. Exhale slowly for 8 seconds. Feel your hands slowly come back together as your lungs empty.
4. Go straight back into the next inhale. There is no hold on the exhale in this technique.

Why the hold and the long exhale matter

For anyone with a solid tolerance to breath holds, this technique is genuinely relaxing. The inhale followed by the hold builds a kind of pressure. A good way to think of it is that the hold gives you a moment to gather up the tension of the day, and the long exhale is where you let it go.

The exhale is doing real physiological work here, too. A longer exhale relative to the inhale is associated with increased parasympathetic (“rest and digest”) activity: the state your nervous system needs to be in for both relaxation and sleep. A direct study on 4-7-8 breathing found that after practising it, markers of parasympathetic activity increased while markers of sympathetic (“fight or flight”) activity decreased in healthy adults.

An important caution

This one only works if you are genuinely comfortable with the hold. If you are pushing yourself too hard on the 7-second hold, it can tip into feeling panic-inducing rather than relaxing, the opposite of what you are going for. You should be able to do several rounds without any sense of air hunger or panic. If you cannot yet, use one of the easier modifications above rather than forcing the full count. Building that comfort is exactly what CO2 tolerance training is for.

This also is not a technique for right before you need to be alert or active. It is built for winding down, not gearing up. Save it for after a stressful day, or in the hour or two before bed. If it is racing, breathwork for anxiety covers more tools for calming anxious thoughts, and if you are new to all of this, what is breathwork is a good place to start.

The best time to practise for sleep

A common assumption is that this technique is something you do once you are already in bed trying to fall asleep. In practice, it tends to work better in the hours leading up to bed rather than in bed itself. By the time you are lying down struggling to sleep, your mind is often already wound up, and it needs a bit of time to settle rather than an instant switch.

Think of it as a delayed reaction: the breath relaxes the body first, and the mind gently follows a little after. That said, if you did not get to it earlier and you are only starting once you are in bed, that is completely fine too. Just keep the rounds going. A timer running in the background can help you stay with it without needing to count in your head, which is one of the things the Be Remindful app is designed for as a daily practice.

If you would like to be guided through techniques like this in person, we run private one-on-one sessions and group sessions, and the app includes a short daily practice you can use anywhere.
