Box breathing vs 4-7-8: neither is proven better, but a longer exhale may matter most. Which to use at work, in bed, and when to skip the holds.
Neither box breathing nor 4-7-8 breathing has been shown to beat the other, and no head-to-head trial appears to exist. What sets them apart is the out-breath: 4-7-8 makes it twice as long as the in-breath, and a long exhale has slightly better evidence behind it.
So choose by what each one asks of you. Box breathing is easy to do with your eyes open at a desk. 4-7-8 has a long hold and a whooshing exhale that suit your bed better than a meeting.
You've probably tried both by now. Box breathing before a call, 4-7-8 at midnight, and either you couldn't tell if anything happened or the seven-count hold left you more wired than before. Try changing the hold before you give up on the technique.
How Do Box Breathing and 4-7-8 Compare?
Both are slow patterns with a breath hold built in. They differ in how long you hold and how the in-breath compares with the out-breath.
If each count lasts about a second, one round of box breathing takes 16 seconds, so under four breaths a minute. A round of 4-7-8 takes 19 seconds, which is closer to three. That's very slow.
A 2018 review looked at 15 studies in healthy adults aged 18 to 65. It drew its line for slow breathing at fewer than 10 breaths a minute. Slow breathing raised heart rate variability, a marker of how easily your body shifts from stress to rest. People also felt more relaxed and less anxious, though the authors called the evidence limited.
Slower isn't automatically better. The UK's NHS stress exercise has no hold. It's breathing in gently for a count of five and out for five, for at least five minutes. At a second per count, that's about six breaths a minute.
Why the Exhale Matters More Than the Count
When researchers change the ratio of in-breath to out-breath, a longer out-breath tends to feel calmer. The evidence is small, but it points the same way twice.
In one study, 30 people tried four breathing patterns at either 6 or 12 breaths a minute. A short in-breath with a long out-breath (roughly three parts in to seven parts out) led to more reported relaxation and stress reduction than the reverse. The long exhale also raised heart rate variability, but only at the slower pace. The authors concluded the ratio shapes the effect, not just the speed.
4-7-8 comes close to that ratio, with one part in to two parts out, though that study used no breath hold and a faster pace. Box breathing is one to one.
The second hint comes from a Stanford trial that randomized 108 adults, most from an undergraduate psychology class. For a month they did five minutes a day of cyclic sighing, box breathing, fast breathing with holds, or mindfulness meditation. Cyclic sighing is two inhales, one after the other, then a long, slow exhale, with no hold.
Cyclic sighing was the only pattern that lifted mood significantly more than meditation, and it slowed breathing the most. Box breathing raised mood too, but not by enough to stand apart from meditation. Anxiety dropped in every group, and breathwork as a whole did no better than meditation.
Keep the limits in view. Each group had only 21 to 33 people, the main paper doesn't break down how many were women, and 4-7-8 wasn't tested at all. A month of mostly students practicing at home says little about a woman in her forties, or one a few months after having a baby.
Which Is Better for Anxiety, Box Breathing or 4-7-8?
Neither has been shown to work better for anxiety. What has evidence is relaxation practice in general.
The NIH's integrative health center describes a 2018 review of 16 studies with 856 people who had generalized anxiety, social anxiety or panic disorder. It found relaxation therapy reduced symptoms of anxiety, depression, phobia, and worry. That's relaxation as a whole, not one count.
Pick by setting instead. Box breathing works before a presentation or in the car after a hard appointment, because nobody can see you doing it. If a hold makes your chest tighten, breathe in for four and out for six or eight, with no hold at all. For the minutes before a call when your heart is already racing, what calms anxiety fast goes step by step.
Which Is Better for Sleep?
4-7-8 is often sold as a way to fall asleep, but neither pattern is a sleep treatment. NCCIH says relaxation techniques on their own don't seem especially promising for sleep.
Cleveland Clinic notes that Dr. Andrew Weil, who popularized 4-7-8, recommends sitting upright, though you can lie in bed if you're using it to fall asleep. Learn it in the daytime first, so you're not counting and judging at the same time. Breathwork for sleep explains why trying too hard to fall asleep can keep you awake.
If you'd rather use one pattern every day, a daily breathwork practice that survives busy days covers how to make it stick.
Who Should Skip the Breath Holds?
Skip or shorten the holds if they make you dizzy, short of breath or panicky. Check with a doctor first if you're pregnant or have a heart or lung condition.
Some lightheadedness is normal at first. Cleveland Clinic says beginners at 4-7-8 may experience "a little bit of lightheadedness or shortness of breath" while they get used to breathing slowly. Shorten every count and keep the out-breath longer than the in-breath. Stop and breathe normally if you feel faint.
Tingling is a different signal. MedlinePlus lists numbness and tingling in the arms or around the mouth as signs of overbreathing, along with feeling dizzy or weak. If that happens, you're probably pulling in too much air on each breath, so take smaller breaths and drop the hold.
Panic disorder needs more care. The NIH's mental health institute lists difficulty breathing, dizziness and tingly or numb hands among the physical signs of a panic attack. It also says women are more likely than men to develop panic disorder. If a seven-count hold feels like the start of an attack, it isn't helping.
The same institute says cognitive behavioral therapy is the gold standard talk therapy for panic disorder. Exposure-based therapy may be paired with relaxation exercises and breathing training. That puts breathing as one part of treatment, not the treatment. If you're not sure what you're having, how to tell a panic attack from an anxiety attack sets out the differences.
NCCIH adds that a few people feel increased anxiety, intrusive thoughts or fear of losing control during relaxation practice. It notes rare reports of worse symptoms in people with epilepsy, certain psychiatric conditions, or a history of abuse or trauma. If a pattern brings any of that on, stop and tell your doctor or therapist.
When to See a Doctor
See a doctor if you often feel short of breath, dizzy or panicky outside of practice. Go sooner if panic attacks start to get in the way of work, sleep or family life.
MedlinePlus says rapid breathing for the first time may be a medical emergency, and to go to the ER right away. If breathing trouble comes on suddenly or is bad enough that you can't talk, call 911 (999 in the UK) or your local emergency number.
If panic comes with thoughts of harming yourself, call or text 988 in the US or Canada, any time. In the US that's the 988 Suicide & Crisis Lifeline, and in Canada it's the 9-8-8 Suicide Crisis Helpline. If your life is at risk or you can't keep yourself safe, call 911 or go to the nearest ER.
In the UK and Ireland, Samaritans are free on 116 123, any time. Anywhere else, use your local emergency number.
The broader picture of what slow and fast breathwork do explains why fast breathing with holds is a different practice altogether.
Frequently Asked Questions
Can You Do Box Breathing and 4-7-8 on the Same Day?
Yes. Both are slow patterns, and NCCIH says relaxation techniques are generally considered safe for healthy people. Box breathing at your desk and 4-7-8 in bed is a reasonable split, as long as neither leaves you dizzy.
Is 4-7-8 Breathing Safe?
For most healthy people, yes, though you may feel a little lightheaded at first. Shorten the counts if the hold feels like a strain. Ask your doctor first if you're pregnant, have a heart or lung condition, or have panic attacks.
How Long Should You Do Box Breathing?
Cleveland Clinic suggests three to four rounds, once or twice a day. The Stanford trial used five minutes a day for a month. If you want longer sessions, the gentler NHS count, with no holds, is easier to keep up.
