Box breathing vs. 4-7-8: which to choose

The two, side by side

Box breathing 4-4-4-4 has four phases of 4 seconds each: you breathe in, hold with air, breathe out and hold on empty, all through the nose. Each round takes 16 seconds, a little under four breaths a minute. The guided session runs 4 minutes, or 15 rounds.

4-7-8 breathing has three phases: you breathe in through the nose for 4 seconds, hold for 7 and breathe out through the mouth for 8, with an audible whoosh. Each cycle takes 19 seconds, about three breaths a minute. The session is just four cycles: 76 seconds.

How they differ

• The holds. Box breathing has two short ones: one with air and one without. 4-7-8 has a single hold, with air, nearly twice as long as the inhale.
• The exhale. In box breathing it's as long as the inhale. In 4-7-8 it's twice as long.
• Where the air goes out. Nose for box breathing. Mouth for 4-7-8, with the tip of your tongue behind your upper front teeth.
• How much you do. Box breathing is counted in minutes. 4-7-8 is counted in cycles, and not many: Andrew Weil says no more than four in a row for the first month and no more than eight after that.
• What you notice most. In box breathing, the hold on empty. In 4-7-8, the 7-second hold and sometimes a little lightheadedness the first few times, which Weil mentions and says will pass.

Where each one comes from

The name box breathing was made famous by Mark Divine, a former Navy SEAL. In a piece published in TIME in 2016, he says its effect is neutral: it neither charges you up nor makes you sleepy, and it leaves a calm body and an alert mind. Cleveland Clinic lists it as another name for sama vritti, yoga's equal-phase breathing.

4-7-8 is known through Dr. Andrew Weil, who teaches it as the relaxing breath. His patient handout says the ratio matters, not the exact time, and that if the hold is hard you can count faster. Cleveland Clinic says Weil popularized it in 2015 and that its roots are in pranayama.

Both, then, are modern versions of something yoga has done for a long time: counting the phases of the breath.

What the studies say

We found only one study that put them head to head. In 2025, Marchant and colleagues compared box breathing, 4-7-8 and breathing at six breaths a minute in 84 college students. Six a minute raised heart rate variability more than the other two. None of them meaningfully changed mood or blood pressure. Between box and 4-7-8, no winner emerged.

Taken separately, there's a little more. In the 2023 Stanford trial, 21 people did box breathing five minutes a day for 28 days. Positive mood went up and state anxiety went down, but with no significant difference from meditation, and sleep measures didn't change in any group. A 2021 study of 30 people compared tactical breathing, a close relative of box breathing, with prolonged exhalation during a task with noise and time pressure: tactical breathing brought lower physical arousal, and the long exhale brought better performance.

On 4-7-8, a 2022 study of 43 healthy people aged 19 to 25 measured what happened right after they practiced it lying down: heart rate and systolic blood pressure dropped. It didn't measure whether they slept better.

These are small, short studies. None shows that either one is better for sleep or for calming down. What follows rests on how the patterns are built and on what people who practice them report.

Which to try for which moment

• Before something demanding (an exam, a meeting, a hard conversation): box breathing. The even count holds your attention, and many people feel it steadies them without making them drowsy.
• In bed or at the end of the day: 4-7-8. The long exhale and the few cycles suit letting go of the day. That's its best-known use, even if it's experience and not a measured result.
• If you have one minute: 4-7-8, which takes 76 seconds.
• If you want a longer practice: box breathing, at 4 minutes.
• If the hold on empty bothers you: Triangle breathing 4-4-4 is a box without the last side.
• If 7 seconds feels too long: 4-4-8 breathing keeps the 8-second exhale with a 4-second hold, all through the nose.
• If you don't want to hold your breath at all: neither one. Start with a slow pattern that has no holds.

How to decide for yourself

Try each one for a week, at the same time of day, and note in your journal how you arrive and how you leave. Two weeks of your own experience will tell you more than any general comparison. You can keep both: one for the day and one for the night.

Do them seated or lying down, never in water and never while driving. If you feel dizziness that doesn't pass, tingling or shortness of breath, drop the pattern and breathe normally. A hold shouldn't feel like a fight.

If you're pregnant or have a heart, lung or blood pressure condition, or a history of fainting or panic attacks, check with your care provider first. And if what you're after is help with insomnia that has lasted weeks or anxiety that overwhelms you, that's a job for a health professional, not for a count.
