Box Breathing: Steps, Uses and Safety

Box breathing is a slow, counted breathing pattern with four equal parts: in, pause, out, pause. Picture tracing the four sides of a square, one side per part. It’s also called square, four-square or 4-4-4-4 breathing, and Cleveland Clinic links it to the yogic practice of *sama vritti* (equal breath).

If you’re new to breathing practice, learn diaphragmatic (belly) breathing first. It teaches relaxed, low breaths with no pauses, and box breathing simply adds two short holds and a steady count. You’ll find more techniques in our Breathing guides.

How to do box breathing

Sitting is the easiest way to learn it, and it lets you practice almost anywhere.

1. Sit in a chair with your back supported and both feet flat on the floor. Rest your hands on your thighs and let your shoulders drop.
2. Breathe out slowly through your mouth until your lungs feel comfortably empty. Don’t squeeze out the last bit.
3. Breathe in gently through your nose while you count to four in your head. Let the breath reach low, so your belly widens.
4. Pause with the air in and count to four. Keep your jaw, throat and shoulders soft: it’s a rest, not a clamp.
5. Breathe out slowly for a count of four, through your nose or gently parted lips.
6. Pause again with your lungs empty for a count of four. Then start the next breath in.
7. That’s one round. Do three or four rounds, then breathe normally for a moment before you stand up.

These steps follow Cleveland Clinic’s method, which starts with a slow full exhale, then four counts each of breathing in, holding, breathing out and holding, for three to four rounds. Its specialist advises staying at your comfort level and breathing gently without straining (Cleveland Clinic). A video from Sunnybrook Health Sciences Centre teaches the same idea by having you picture moving around the sides of a box as you breathe. You can also trace a square with one finger on your leg.

How to shorten the counts if four feels too long

The count is a guide, not a test. If four makes you gasp, rush or tense up, make every side of the box shorter.

Version	In	Hold	Out	Hold	One round takes about
Shorter	3	3	3	3	12 seconds
Classic	4	4	4	4	16 seconds
Longer (only once 4 is easy)	5	5	5	5	20 seconds

In a Stanford study, people were given box counts of 3 to 4, 5 to 6 or 8 to 10 seconds, based on a simple breathing test, and were told to shorten every count if they ever had to strain (Balban et al., 2023). Use the same rule: shorten first and lengthen later. Cleveland Clinic notes that holding a steady count can feel hard at first and gets easier with practice.

If the pauses are the hard part, keep them shorter than the other sides, for example 4-2-4-2. That isn’t a perfect square any more, but it’s a gentler start. Researchers have also tested softer variations, such as 4 seconds in, a 2-second pause and 4 seconds out (McAllister et al., 2026, summarizing earlier work).

How long and how often should you do it?

Source	How long	How often
Cleveland Clinic (box breathing)	3 to 4 rounds	Once or twice a day, however you feel
Cleveland Clinic (breathwork in general)	5 to 10 minutes	Daily
Stanford study (Balban et al., 2023)	5 minutes	Daily for about a month

A few rounds take only a minute. If you’d like to build up, add a round at a time until you reach about 5 minutes, and stop sooner if you feel lightheaded. Cleveland Clinic suggests practicing in calm moments, such as first thing in the morning, so the pattern comes more easily when you’re stressed.

When people use box breathing

• Before a stressful task. People use a few rounds before a presentation, an exam, a hard conversation or a medical appointment. One study tested exactly this, 5 minutes before a lab stress test, with encouraging short-term results (see the research box below). That doesn’t promise it will work for you.
• During a busy day. Cleveland Clinic suggests it as an anytime practice, at your desk or while you wait in line. It also says not to do it while driving (Cleveland Clinic).
• Winding down in the evening. A few calm rounds can be part of how you settle before bed. Be realistic: NCCIH notes that relaxation techniques alone haven’t shown much promise for sleep (NCCIH), and in the Stanford study none of the breathing groups slept differently after a month. For a fuller evening wind-down, pair it with our bedtime yoga guide.
• Not between hard intervals. In 40 active students, box breathing during short rests between hard cycling efforts led to a higher heart rate than slow breathing at six breaths a minute, and higher perceived effort than either slow or normal breathing (Kasap and Aydin, 2025). During rests between hard efforts, breathe freely or slow your breathing without holds.

Common mistakes

• Straining during the holds. A hold should feel like a pause at the top or bottom of a swing. Don’t close your throat and push. Pushing air against a closed mouth and nose is the Valsalva maneuver, which briefly changes blood pressure and heart rate and is used on purpose only under medical guidance (Cleveland Clinic).
• Gulping air. Taking huge breaths, or breathing hard to “make up” for the pauses, can tip you into overbreathing. That can make you lightheaded or dizzy and cause tingling around your mouth or in your arms (MedlinePlus). Keep each breath comfortable rather than big.
• Forcing long counts. Counting to six or eight before you’re ready makes the holds tense. Go back to four or three.
• Breathing into your chest and shoulders. If your shoulders rise on every breath, practice belly breathing on its own first.
• Counting too fast. Rushing the count to “get through” a round defeats the point. Aim for roughly one count a second, the pace used in studies (McAllister et al., 2026).
• Waiting for a crisis. A new skill is hard to use for the first time when you’re upset. Practice when you’re calm.

How box breathing compares with other slow-breathing methods

Method	Pattern	Breath holds?
Box breathing	In 4, hold 4, out 4, hold 4	Two equal holds each round
Diaphragmatic breathing	Slow, comfortable breaths that move the belly	None
4-7-8 breathing	In 4 through the nose, hold 7, out 8 through the mouth	One long hold; the out-breath is the longest part
Alternate nostril breathing	Breathe in through one nostril and out through the other, then switch sides	Short pauses of a beat or two in Cleveland Clinic’s version
Cyclic sighing	Two breaths in, one long, slow breath out	None

The 4-7-8 pattern comes from Cleveland Clinic, which suggests it for bedtime, while box breathing is the one it calls easy to do on the go (Cleveland Clinic). Cyclic sighing is the exhale-focused pattern from the Stanford study (Balban et al., 2023), and the alternate nostril steps follow Cleveland Clinic. If breath holds don’t suit you, the methods without holds are the easier choice.

Frequently asked questions

Does box breathing work for anxiety?

It may ease anxious feelings in the moment. In the small trials above, people felt less anxious right after box breathing, and in one trial it softened the rise in anxiety and heart rate during a stressful task. But it didn’t outperform mindfulness meditation in the Stanford study, and no study shows it works as a long-term fix. Box breathing is not a treatment for anxiety disorders. If anxiety gets in the way of daily life, talk to your doctor.

Is box breathing the same as 4-7-8 breathing?

No. Box breathing keeps all four parts the same length and holds the breath twice. The 4-7-8 method holds once, for longer, and makes the out-breath the longest part (Cleveland Clinic). Cleveland Clinic calls 4-7-8 a bit more complex than box breathing (Cleveland Clinic).

Why do Navy SEALs use box breathing?

Box breathing is widely linked to the military. Cleveland Clinic says it is used by U.S. Navy SEALs, and a Stanford research team writes that soldiers have used it to manage stress (Balban et al., 2023). We found no official Navy source describing how it’s taught. Military psychologists who studied a related “tactical breathing” method called the evidence for it limited. In their own small lab test with 30 healthy adults, tactical breathing calmed the body slightly more than a long-exhale method, but people performed a task better with the long exhale (Röttger et al., 2021). Its popularity is real; it doesn’t prove the method works better than other slow breathing.

Is box breathing a form of meditation?

Partly. Cleveland Clinic’s specialist describes the silent counting as a kind of mantra meditation that helps you stay in the present moment. You don’t need any meditation experience to try it.

Why does box breathing make me dizzy or more anxious?

Dizziness usually means you’re breathing too deeply or too hard between the holds. Make the counts shorter and the breaths smaller. Some people feel uneasy when they hold their breath. If that’s you, skip the holds and simply breathe in and out slowly, or try diaphragmatic breathing. If dizziness keeps coming back, stop and talk to your doctor.

Can you do box breathing lying down?

Yes. Participants in the Stanford study could sit in a chair or lie down. Sitting upright makes it easier to stay alert and keep the count, and it’s the safer choice in later pregnancy. If you’re new to yoga as well, our guides to yoga for beginners and starting yoga at home show you where to begin.
