Box breathing is a calming breathing technique with four equal steps: breathe in for a count of four, hold for four, breathe out for four and hold for four, then repeat. Cleveland Clinic suggests three to four rounds. Keep it gentle, use shorter holds if four counts feels hard, and stop if you feel dizzy.
When your head's racing before a big meeting or you can't switch off at night, being told to just breathe can feel unhelpful. Box breathing gives that advice a simple shape you can follow, which is why so many people find it easier to stick with than a vague instruction to relax.
I've pulled this guide together from Cleveland Clinic, the Dana-Farber Cancer Institute's Zakim Center and the NHS breathing exercise page. It's general wellbeing information. If stress, anxiety or panic are affecting your daily life, please talk to your GP or contact NHS Talking Therapies, and there's more on getting support further down.
Box breathing in a nutshell
Box breathing is a breathing pattern with four equal steps: breathe in, hold, breathe out, hold. Each step lasts the same count, so if you picture it, you're tracing the four sides of a square. Cleveland Clinic notes it also goes by names such as square breathing, four-square breathing, 4-4-4-4 breathing and equal breathing, and links it to a yogic practice called sama vritti pranayama.
Cleveland Clinic says the technique is used by the United States Navy SEALs, as well as by stressed-out people everywhere. You don't need any equipment, and you can do it sitting at a desk, on a train or in bed.
How to do box breathing step by step
These steps follow the instructions from Cleveland Clinic and the Zakim Center. Sit somewhere comfortable with your back supported and your feet on the floor.
- Breathe out slowly, emptying your lungs.
- Breathe in gently through your nose for a count of four.
- Hold your breath for a count of four.
- Breathe out slowly through your mouth for a count of four.
- Hold your breath again for a count of four.
- Repeat the cycle. Cleveland Clinic suggests three to four rounds, while the Zakim Center suggests several cycles over three to five minutes or more.
Cleveland Clinic stresses keeping it gentle: stay at your comfort level and don't strain. The counts can feel hard at first, and with practice many people find they can slow their breathing down over time.
Box breathing for beginners: shorter counts
If a four-count hold feels like too much, you don't have to force it. The Zakim Center suggests starting with holds of two to three seconds and building up gradually. You could try a pattern like this at first:
| Step | Starter pattern | Standard pattern |
|---|---|---|
| Breathe in | 4 counts | 4 counts |
| Hold | 2 to 3 counts | 4 counts |
| Breathe out | 4 counts | 4 counts |
| Hold | 2 to 3 counts | 4 counts |
The NHS breathing exercise for stress uses a simpler rhythm with no holds: breathe in gently through your nose counting from one to five, then out through your mouth counting from one to five, for at least five minutes. If holding your breath doesn't suit you, that version's a good alternative.
When people use box breathing
Cleveland Clinic suggests practising once or twice a day, regardless of how you feel, such as first thing in the morning or after a stressful day. People also reach for it in moments like these:
- Before a presentation, interview or difficult conversation.
- When work feels overwhelming and you need a short reset.
- At bedtime, to help you wind down.
- During a commute or while waiting for an appointment.
The NHS makes a similar point about its own breathing exercise: you'll get the most benefit if you do it regularly, as part of your daily routine, rather than only when you're already stressed.
What box breathing may do
Cleveland Clinic describes a few possible effects. Regulating your breath may help reduce stress hormones, and it may help shift your nervous system away from fight-or-flight towards a calmer rest-and-digest state. Counting also works a bit like a simple meditation, bringing your attention back to the present moment.
Those are possibilities, not promises. Breathing exercises are a self-help tool, and they're not a replacement for support from a healthcare professional when you need it.

Box breathing cautions
- Feeling dizzy or light-headed. The Zakim Center says to slow down or stop if this happens.
- Straining to hold. Use shorter counts and keep each breath gentle.
- Tight clothing. The NHS suggests loosening anything that restricts your breathing, if you can.
- Breathing conditions. If you have asthma, a lung condition or a heart condition, ask your GP or healthcare professional whether breath holding suits you.
- It makes you more anxious. Stop and try the NHS version without holds, or another way to unwind.
Getting support for stress and anxiety
Breathing techniques can help in the moment, but they won't fix everything. If worry, low mood or panic are hanging around, your GP is a good first step. You can also refer yourself to NHS Talking Therapies for anxiety and depression if you're registered with a GP and aged 18 or over, or 16 and over in some areas.
If you need help urgently, the NHS says to call 111 and select the mental health option, or use 111 online. You can call Samaritans on 116 123. Call 999 or go to A&E if someone's life is at risk.
