Slower4-7-8 vs box breathing: 4-7-8 is in for 4, hold for 7, out for 8, a 19-second round that suits bedtime. Box breathing is in 4, hold 4, out 4, hold 4, a 16-second round that keeps you alert and suits the minutes before a demanding task. Neither is better overall. Pick by the situation.
Try both first
Two minutes of each will tell you more than any article. Open the 4-7-8 breathing timer and do four rounds, then run the box breathing timer for a couple of minutes. You will probably have a favorite by the end.
Side by side
| 4-7-8 breathing | Box breathing | |
|---|---|---|
| Pattern | In 4, hold 7, out 8 | In 4, hold 4, out 4, hold 4 |
| One round | 19 s at one second per count | 16 s |
| Breaths per minute | About 3.2 | 3.75 |
| Feels like | Heavy and loose, with one long letting-go breath out. A little light-headed the first few times. | Steady and squared off. Calm but awake, with your mind busy counting. |
| Best for | Settling down at night | Focus and composure before a demanding moment |
| Hardest part | The 7-second hold followed by the 8-second exhale | The second hold, on empty lungs |
What is really different
Both are slow, counted breaths with holds, and both run at under four breaths a minute. The difference is the shape. In 4-7-8 the breath out is twice as long as the breath in, and a 2014 experiment found that a longer exhale adds to the relaxing effect of slow breathing. That may be why 4-7-8 leaves many people heavy and a bit drowsy.
Box breathing has four equal sides. No part dominates, and the two holds keep you slightly alert. It comes from military and police training, where the goal was a clear head, not sleep.
The complaints differ too. With 4-7-8, people run out of air on the long exhale or find the 7-second hold a strain. The fix is to count faster: the person who popularised it taught that the 4:7:8 ratio matters, not the speed of the count. With box breathing, the empty hold is what bothers people, especially if they are already anxious. Dropping to three seconds a side usually sorts it out.
Which one to use, by situation
- In bed, mind still going: 4-7-8. Four rounds, then let your breathing go back to normal. More on this in breathing to fall asleep.
- Ten minutes before a meeting, exam or hard conversation: box breathing. It steadies you without making you sleepy.
- Wound up right now, and holding your breath sounds awful: neither. Use long exhale breathing, in for 4 and out for 6, with no holds at all.
- A daily habit for general calm: see the third option below.
If you only want to learn one, our honest pick is box breathing at three or four seconds. It is easier to get right on the first day, and you can do it in a meeting without anyone noticing. 4-7-8 is taught with a whooshing exhale through the mouth, which is fine in bed and awkward in an open office.
What the head-to-head study found
A 2025 study put 84 students through 4-7-8, box breathing and plain slow breathing at six breaths a minute. The plain slow breathing raised heart rate variability more than either of the famous patterns. None of the three changed mood or blood pressure in a single session.
So the research does not crown a winner between these two. The evidence behind each is also thinner than their fame suggests. Box breathing improved mood in a 2023 Stanford trial of five minutes a day for a month, alongside the other exercises tested. For 4-7-8 there is no proper trial for sleep, only one small study with mixed results on heart rate and blood pressure.
The third option
Slow, even breathing with no holds, five seconds in and five out, did more for heart rate variability than either pattern in that comparison. It is less famous because there is no catchy count to remember. The coherent breathing timer paces it for you.
Both patterns include breath holds. Keep them comfortable and never strain. If you feel dizzy or short of air, stop and breathe normally; it passes within a minute. Skip the holds if you are pregnant or have a heart or blood pressure condition, and ask your doctor if you are unsure.
Questions people ask
Which is better, box breathing or 4-7-8?
Neither is better overall. 4-7-8 has a long exhale and suits winding down at night. Box breathing has equal sides, keeps you alert, and suits the minutes before something demanding.
Which is better for sleep, 4-7-8 or box breathing?
4-7-8 is the better fit for bedtime because the breath out is twice as long as the breath in. The holds in box breathing keep you slightly alert. There is no proper trial of either for sleep.
Which is better when I feel anxious?
Many anxious people find breath holds unpleasant, so a pattern without holds is often easier: in for 4 seconds, out for 6. If you prefer a count with holds, try box breathing at 3 seconds a side.
Is 4-7-8 harder than box breathing?
For most beginners, yes. The 7-second hold followed by an 8-second exhale is the most common complaint. Counting faster while keeping the 4:7:8 ratio makes it manageable.
Can I do both on the same day?
Yes. One way to split them is box breathing during the day, before demanding moments, and four rounds of 4-7-8 at bedtime.
Is there something that works better than both?
In a 2025 comparison, plain slow breathing at six breaths a minute raised heart rate variability more than box breathing or 4-7-8. None of the three changed mood in a single session.
