Box breathing vs 4-7-8

Neither has clearly won. In the one study that tested both head to head, neither changed mood much in a single sitting, and a steady 6 breaths a minute did more for heart rate variability than either.1 Box breathing is easier to remember and to do with your eyes open, while 4-7-8 has a long breath out that many people like for winding down.

The table was checked on October 30, 2026, against the studies and handouts under Sources, and the round times assume one count per second.

How we checked

We read every study we could find that tested box breathing or 4-7-8 breathing, alone or against other patterns, and the original instructions for each. We did not run our own test. The numbers in the table come from the counts themselves.

Which one suits you

Box breathing is the one for public places. Harvard Health says police and military use it under the name tactical breathing.2 Before a meeting or a hard phone call, with your eyes open, equal counts are easy to keep, and you can trace the square in your head.

4-7-8 is the one for bed. The breath out is twice as long as the breath in, and Andrew Weil, the doctor who made the technique popular, suggests it for falling asleep.3,4 Nobody has tested whether it works for that, as far as we could find.

Skip both if the holds make you feel tight or panicky, since relaxation exercises occasionally bring on more anxiety instead of less,5 and breathe in for 4 and out for 6 with no holds, which is gentler and did best in the head-to-head study.1

Try both: press Start for box breathing, then switch the pattern to 4-7-8 and compare how each one feels.

Box breathing: 5 rounds, about 1 min 20 sec.

Pattern

In, hold, out, hold, for the same count. Each step is one side of the square.

If you feel dizzy, short of breath or more anxious, stop and breathe normally. A shorter count is fine. If you're thinking about harming yourself, call or text 988 in the US, or see crisis resources.

Both are slower than the pattern that won

Do the arithmetic. A box round takes 16 seconds, so about 4 breaths a minute, and a 4-7-8 round takes 19, so about 3. The pattern that came out ahead in the one direct comparison was 6 breaths a minute, faster than both, with no holds at all.1

The holds are what slow them down. In 4-7-8, the 7-count hold is more than a third of every round.

The one study that tested both

A tie. And on heart rate variability, a simple slow breath beat them both.

In 2025, 84 college students tried four patterns in one lab visit (box, 4-7-8, and two ways of breathing at 6 a minute) while researchers measured heart rate variability, a sign the body is shifting toward rest, plus blood pressure, mood and carbon dioxide.1

  • Breathing at 6 a minute raised heart rate variability more than box or 4-7-8 breathing, with small to medium effects.1
  • None of the four patterns changed mood or blood pressure in a meaningful way in one sitting.1
  • The 6-a-minute pattern also brought mild over-breathing: carbon dioxide dropped a little.1 That trade-off is one reason to stop if you feel dizzy or tingly.

The authors' own first line: both techniques are "popularly promoted by psychotherapists but have little empirical support".1

Each one's best case

Box breathing's best case is sitting still under stress, a waiting room rather than a task. In the one test with a task, it lowered physical arousal more than a long exhale did, yet people performed better with the long exhale.6 That study, and a 28-day one where cyclic sighing did best, are on the box breathing page.7

4-7-8's best case is a slow wind-down at night, though no study has tested either technique for falling asleep. Its own small studies measured other things: heart rate and blood pressure in 43 young adults, and anxiety after weight loss surgery in 90 patients.8,9 The 4-7-8 page has both.

For sleep trouble that lasts weeks, cognitive behavioral therapy for insomnia is the first-line treatment.10

When to switch or stop

Both can make you lightheaded at first. Relaxation techniques are generally safe for healthy people, though now and then they bring on more anxiety or a fear of losing control, so stop and breathe normally if you feel dizzy, tingly, short of breath or more anxious.5

If that happens, switch to the longer exhale. Or leave the breath alone completely with 5-4-3-2-1 grounding.

If you're thinking about harming yourself, call or text 988 in the US, or see crisis resources.

Questions people ask

Is box breathing or 4-7-8 better for anxiety?

No study has compared them for anxiety directly. Breathwork in general lowered anxiety a little, across 20 randomized trials,11 and in the 28-day study the pattern with the longest exhale, cyclic sighing, lifted mood the most.7

Can you do 4-7-8 breathing all day?

Weil's handout says no more than 4 breaths at a time for the first month, at least twice a day, building to 8 breaths later.4 Nobody has studied doing more than that.

Who should not do box breathing?

Anyone with trouble breathing, on oxygen, or who gets dizzy easily should talk with a doctor first.12 If the holds raise your anxiety, drop them and use a longer exhale.

The verdict

Use box breathing when you want a simple, even pattern you can do anywhere, and 4-7-8 when a long breath out helps you wind down. If you only learn one, a slow breath in for 4 and out for 6 has at least as much support as either.
