How to do 4-7-8 breathing

4-7-8 breathing is a slow breathing exercise with three counts. Breathe in quietly through your nose for 4, hold your breath for 7, then breathe out through your mouth for 8 with a soft whoosh. That's one round. Do four rounds, which takes a little over a minute, then let your breath go back to normal. The long out-breath and the very slow pace settle your body, which is why people use 4-7-8 breathing to fall asleep and to take the edge off anxiety.

Try one round while you read. Breathe all the way out first. In, 2, 3, 4. Hold, 2, 3, 4, 5, 6, 7. Out, 2, 3, 4, 5, 6, 7, 8.

What 4-7-8 breathing is

The 4-7-8 breathing technique was developed by an American physician, Andrew Weil, and is based on pranayama, the breath control practiced in yoga. The numbers are the counts for each part of the breath: 4 breathing in, 7 holding, 8 breathing out. It was designed to ease anxiety and make it easier to fall asleep.

Two things set it apart from ordinary slow breathing. The out-breath is twice as long as the in-breath, and the whole pattern is very slow. At one count per second, a single round takes 19 seconds. In a 2022 study of 43 young adults, that worked out to roughly three breaths a minute. After three sets of six rounds lying down, people's heart rate dropped by about 3 to 5 beats a minute and their systolic blood pressure (the top number) came down too. That held both for people who had slept normally and for people who were short on sleep. In the well-rested group, heart rate measures tied to the calming side of the nervous system also rose.

The numbers are easy to scramble when you're tired, and people mix up the order all the time. Remember that they climb. The shortest count is the breath in, the middle one is the hold, and the longest is the breath out. If you forget everything else, keep the out-breath longest.

You may know box breathing, the other famous counted breath. It uses four equal counts and two holds. 4-7-8 has a single hold and puts the weight on a long exhale, which makes it a natural fit for bedtime.

How to do the 4-7-8 breathing technique

Here's the 4-7-8 breathing exercise step by step. Sitting is easiest while you learn, because you're less likely to drift off and lose count.

1. Get comfortable. Sit with your back supported and your feet flat on the floor, or lie on your back. Drop your shoulders and let your jaw go loose.
2. Place your tongue, if you like. Some instructions have you rest the tip of your tongue on the ridge just behind your top front teeth and keep it there the whole time. It's optional. Skip it if it feels strange.
3. Empty your lungs. Breathe all the way out through your mouth with a whoosh.
4. Breathe in for 4. Close your lips and breathe in quietly through your nose, counting 1, 2, 3, 4.
5. Hold for 7. Keep your throat and shoulders soft. Think of it as a pause rather than a clench.
6. Breathe out for 8. Let the air go through your mouth with the whoosh. Purse your lips a little so it leaves slowly enough to last all eight counts.
7. Repeat. Go straight into the next breath in. Do four rounds in total, then breathe normally and notice how you feel.

A few things make it easier:

• Keep the ratio, not the seconds. How fast you count is up to you. What matters is that the hold is a little under twice the in-breath and the out-breath is twice the in-breath.
• Take a normal breath in. You don't need to fill your lungs to bursting. A comfortable, quiet breath is enough.
• Make the whoosh silent when you need to. In a shared bed or a quiet office, breathe out through pursed lips without the sound. It works the same.
• Use a timer the first few times. Anxiety tends to speed up your counting without you noticing, and a timer keeps the pace honest.

4-7-8 breathing for sleep

4-7-8 breathing for sleep works on two things that keep you awake: a body that's still revved up and a mind with nothing calm to hold on to. The slow pace and long out-breath help your heart rate come down. Counting to 7 and then to 8 takes just enough attention that tomorrow's to-do list has a harder time getting in.

Here's how to use the 4-7-8 breathing method for sleep:

1. Get into bed when you're sleepy. Lights off, phone face down and out of reach.
2. Do four rounds on your back. Breathe out silently if someone is sleeping next to you.
3. Stop counting. Let your breathing go back to its own rhythm and let your arms and legs get heavy.
4. Go again if your mind starts up. Breathe normally for a minute, then do another four rounds. That's close to how the study above ran it, with a minute of normal breathing between sets.
5. Get up if it isn't happening. Still wide awake after 20 minutes or so? Lying there and trying harder rarely helps. Here's what else helps you fall asleep fast, including when to get up for a while.

The same routine works when you wake at 3 a.m. and your thoughts switch on. Four rounds, then normal breathing, and no checking the clock. Here's more on why you keep waking up in the middle of the night.

The research on 4-7-8 sleep breathing is still small, but it points the right way. In a randomized trial of 48 people with tinnitus, the group who did four rounds of 4-7-8 breathing twice a day for six weeks scored lower on insomnia at the end, and lower on stress and anxiety too. The group who only got an information session didn't change.

You'll see 4-7-8 promised as a way to fall asleep in 60 seconds. There's no research behind that number. Use it to get your body ready for sleep, then let sleep come when it's ready. Expecting it to knock you out on the spot only gives you something new to worry about at midnight.

4-7-8 breathing for anxiety

4-7-8 breathing for anxiety works best when you can see the stress coming. Good moments to use it:

• In a waiting room before an appointment or a procedure.
• Before a hard conversation, an interview or a talk.
• Before you open the message or email you've been dreading.
• When a worry starts looping late at night.

Most of the anxiety research so far comes from hospitals, where nerves run high. In a randomized trial of 90 patients after weight-loss surgery, the group taught 4-7-8 breathing ended up with lower anxiety than a group taught deep breathing and a group given routine care. In a trial of 75 older adults waiting for an endoscopy, fear and anxiety scores were lower after 4-7-8 breathing, while both rose in the group who waited without an exercise.

In the middle of a panic attack, a 7-count hold can feel like too much. If holding your breath makes your chest feel tighter, skip the hold and just make the out-breath long: in for 4, out for 8. For other breaths that work when anxiety is already high, like the physiological sigh, see our guide to deep breathing for anxiety.

Your body usually calms down faster than the worry does. When the breathing has done its job, that's a good time to say what's bothering you out loud or type it out, while you're steady enough to look at it clearly.

Getting the count right if you feel lightheaded

If you feel lightheaded or tingly while you do 4-7-8 breathing, the count usually needs adjusting. The pattern is far slower than you normally breathe, and big gulps of air followed by a forceful blow-out can leave you dizzy. Small changes fix it:

• Count faster. Say the numbers at about twice your usual speed, so a whole round takes under 10 seconds instead of 19. The ratio stays the same. Slow the count down as it gets easier.
• Breathe in less. A normal, quiet breath through your nose is plenty.
• Ease the out-breath. Let the air leave slowly through pursed lips. You don't have to squeeze out the very last bit.
• Shorten the hold. If 7 feels like a strain, count the hold faster than the other two parts until it stops feeling like a fight.
• Sit or lie down, and stop at four rounds. Don't practice it standing up or while driving.
• Stop if the room spins. Breathe normally until the feeling passes. Next time, start with two rounds at a faster count.

If the hold never feels right, you don't have to keep fighting it. In a lab study of 84 college students, plain slow breathing at six breaths a minute raised heart rate variability, a common sign of a calmer body, more than either 4-7-8 or box breathing did. So in for 4 and out for 6, with no hold at all, is a fine swap on days when 4-7-8 feels like work.

If you get dizzy every time, even with a faster count, or you have a heart or lung condition, ask your doctor which breathing pattern suits you.

How often to practice

A simple plan for your first few weeks:

• Twice a day, four rounds each. That's what the tinnitus trial asked of people for six weeks: four rounds in the morning and four in the evening, sitting somewhere quiet.
• No more than four rounds at a time while you learn. You can come back to it several times a day. That's the usual advice until the pattern feels comfortable.
• Practice when you're calm. A rhythm your body already knows is much easier to find when you're wound up. Tie it to something you do every day, like brushing your teeth, sitting in the car before you drive off or getting into bed.
• Use it in the moment, too. Before the hard thing, or when you're lying awake.
• Check in after two weeks. Are you falling asleep a little faster? Do you reach for it without thinking when your heart starts pounding? If so, it's working for you.

Expect the hold to feel long at first. It gets easier with practice, like any new rhythm.

Quick answers

Is there a sleep app with breathing exercises like 4-7-8 and a chat for racing thoughts?

Yes. Moodu has 4-7-8 breathing built in with an on-screen timer, and a chat you can type or talk into when your thoughts won't settle at night. You can breathe first and then get the worries out of your head, or the other way round. It's open any hour, so 2 a.m. works.

Does 4-7-8 breathing really work?

Yes, for calming down in the moment, and small trials back it up. Studies have found lower anxiety around medical procedures, lower insomnia scores after six weeks of practice and a drop in heart rate right after a session. It's free, takes about a minute and is easy to try tonight.

Let Moodu keep the count

Moodu has 4-7-8 breathing built in, so the count is done for you. An on-screen timer tells you when to breathe in through your nose for 4, hold for 7 and breathe out slowly through your mouth for 8, for four rounds. You follow along instead of counting, which helps when you're exhausted or your head is busy. Start it when you get into bed, then put the phone face down.

Some nights it's more than your breathing that keeps you up. Sleep Serenity, Moodu's guided conversation for sleep, opens with: "Rough nights lately? Tell me what bedtime usually looks like for you and we'll find a calmer routine." From there it asks about your evenings and helps you settle on a wind-down you'll stick to. If your thoughts are racing, saying them to something that answers back helps you set them down for the night. You can type, or tap the mic and say it out loud.

Chats are encrypted before they're saved and never used for ads. Moodu is $39.99 a year after a 3-day free trial, or $4.99 a week.
