Breathing techniques are ways of paying attention to your breath or changing its rhythm on purpose, usually to calm down, focus or wind down for sleep. The most useful ones for everyday stress are simple: breathe into your belly, slow down, and make the out-breath a little longer than the in-breath. Popular patterns such as box breathing and 4-7-8 breathing add counted breath holds. You can try box, 4-7-8 and even breathing with a guide right now in our breathing exercise.
Below are the eight techniques we find most useful, what each is good for, how they compare, and what the research actually shows.
The 8 breathing techniques at a glance
| Technique | Rhythm | Breath hold? | Good for |
|---|---|---|---|
| Breath awareness | Your natural breath, unchanged | No | Meditation, noticing without effort |
| Belly breathing | Slow, deep breaths into the belly | No | Learning to breathe low and slow |
| Even breathing | In and out for the same count, e.g. 5 and 5 | No | A steady rhythm for a few minutes |
| Longer exhale | Out-breath longer than the in-breath, e.g. 4 and 6 | No | Calming down quickly, any time |
| Slow paced breathing | Fewer than 10 breaths a minute | No | Longer practice sessions |
| Cyclic sighing | Two in-breaths through the nose, one long out-breath | No | A short daily reset |
| Box breathing | In 4, hold 4, out 4, hold 4 | Yes | Focus and composure |
| 4-7-8 breathing | In 4, hold 7, out 8 | Yes | Winding down, in bed |
The first six need no breath hold, so they're the easiest place to start.
1. Breath awareness: just noticing
You don't change anything. You follow the breath as it is: where you feel it, how long each in-breath and out-breath lasts, the small pause in between. When your mind wanders, you come back. This is the classic anchor in meditation, and it's the foundation for all the other techniques, because you first need to feel your breath before you change it.
Researchers treat it differently from breathing exercises: a 2018 review of slow breathing techniques explicitly left out "passive" practices such as breath awareness, where slower breathing is only a by-product.
2. Belly breathing (diaphragmatic breathing)
You let the breath flow down into the belly instead of staying high in the chest. The US National Center for Complementary and Integrative Health (NCCIH) describes breathing exercises as focusing on "taking slow, deep breaths," also called diaphragmatic breathing.
How to do it, following the NHS breathing exercise for stress:
- Sit, stand or lie comfortably, and loosen any clothes that restrict your breathing.
- Let your breath flow as deep down into your belly as is comfortable, without forcing it.
- Breathe in through your nose and out through your mouth.
- Breathe in gently and regularly, counting steadily from 1 to 5 if that helps, then let it flow out, counting from 1 to 5 again.
- Keep going for at least 5 minutes.
A hand on your belly helps you feel it rise and fall.
3. Even breathing
In and out for the same number of counts, such as five in and five out. It's calm and easy to keep up, which makes it a good technique for a few minutes of practice. It's one of the three patterns in our breathing exercise, where a circle grows as you breathe in and settles as you breathe out.
Derived number: at five seconds in and five seconds out, one breath takes 10 seconds, so you breathe 6 times a minute (60 ÷ 10). That's the slow range the next technique is about.
4. Longer exhale
You breathe out longer than you breathe in, for example in for four counts and out for six. No hold, no strain. Several of the guided sessions in our app use exactly this 4-6 rhythm, including Acute Stress SOS, because it's easy to do even when you're flustered. If six counts feel too long, shorten the out-breath until it's comfortable.
Why the out-breath? Researchers note that in-breaths increase the heart rate and out-breaths decrease it, a normal effect called respiratory sinus arrhythmia. Exhale-focused techniques build on that. Our guide to breathing exercises for stress has a 2-minute version to use in the moment.
5. Slow paced breathing
Breathing more slowly than usual, on purpose, for several minutes. A 2018 systematic review defined slow breathing as fewer than 10 breaths per minute. In the 15 studies of healthy people it included, slow breathing was linked to more heart rate variability and to changes in brain activity related to emotional control and well-being. The authors call the evidence "interesting albeit limited." The authors of a 2023 meta-analysis note that simply pacing the breath at about 5 to 6 breaths per minute may produce effects similar to heart rate variability biofeedback, without any equipment.
You don't need to count breaths per minute. Even breathing at 5 and 5 gets you there.
6. Cyclic sighing (the physiological sigh)
Breathe in through the nose, then take a second, shorter in-breath on top to fill the lungs, and let all the air out slowly through the mouth. Repeat for a few minutes.
What the study found, and what it can't tell you: In a 2023 Stanford study, participants did one of four practices for 5 minutes a day for a month: cyclic sighing, box breathing, cyclic hyperventilation with breath holds, or mindfulness meditation. All groups reported less anxiety and less negative mood after each session. Cyclic sighing raised positive mood more than mindfulness meditation did, and lowered participants' breathing rate over the month more. The groups were small: 108 people enrolled, 30 were assigned to cyclic sighing and 27 of them had usable breathing-rate data, and most participants were students. People with heart disease and several other medical conditions were excluded. So it's a promising result, not proof that cyclic sighing is the best technique.
7. Box breathing (4-4-4-4)
Breathe in for four counts, hold for four, breathe out for four, hold for four, and repeat. The researchers above describe it as equal inhales, holds and exhales, used by members of the military for stress regulation and performance. The holds make it more demanding; it suits people who like structure and want to feel steady and focused.
We don't repeat the full instructions here: the breathing exercise guides you through box breathing with a timer for one, three or five minutes.
8. 4-7-8 breathing
Breathe in quietly through your nose for four counts, hold for seven, and breathe out through your mouth for eight. The long hold and very long exhale slow everything down, which is why many people use it in bed. The sources on this page don't test 4-7-8 on its own, so we make no claims about its specific effects. Try it guided in the breathing exercise.
Derived numbers: with one count per second, one round of 4-7-8 takes 19 seconds (about 3 breaths a minute) and one round of box breathing takes 16 seconds (3.75 breaths a minute). Both are well within the "fewer than 10" slow range, so start with fewer rounds if you feel lightheaded.
Important
If you feel dizzy, lightheaded or uncomfortable during any breathing technique, stop and return to your normal breathing. If you have a heart or lung condition, talk to your doctor before you practice breath holds, as in box breathing or 4-7-8 breathing.
Which breathing technique should you use?
| Situation | Try |
|---|---|
| You feel a wave of stress right now | Longer exhale, 3 to 5 breaths |
| You want to calm down but not get sleepy | Box breathing or even breathing |
| You're in bed and can't wind down | Belly breathing with a longer exhale, or 4-7-8 |
| You want a daily practice | Even breathing or cyclic sighing, 5 minutes |
| You're meditating | Breath awareness |
| You feel anxious and holding your breath feels bad | Skip holds; use belly breathing or a longer exhale |
For nights specifically, our sleep meditation guide uses a countdown of out-breaths, and our guide for racing thoughts at night has a 4-minute wind-down. If you only have a moment, the 1-minute meditation is built around three slow breaths.
Breathing techniques for anxiety and stress
When you're stressed, the breath often gets faster and shallower. Slowing it is one of the few things you can change on purpose right away. The NHS describes its belly breathing exercise as "a calming breathing technique for stress, anxiety and panic" that "takes just a few minutes and can be done anywhere," and says you get the most benefit from doing it regularly.
For a quick plan that combines breathing with other steps, see how to calm down fast.
Keep it gentle. Long breath holds can feel uncomfortable when you're anxious, so start with belly breathing or a longer exhale. And keep expectations realistic: a breathing technique can take the edge off a moment. It doesn't treat an anxiety disorder, and if anxiety is frequent or strong, talking to a doctor is the right next step.
What research says about breathing techniques
- Stress: A 2023 meta-analysis of 12 randomized controlled trials (785 participants) found that breathwork was linked to lower self-reported stress than control conditions, with a small-to-medium effect. The authors rated the studies overall at moderate risk of bias and asked for better research.
- Anxiety and depression: The same analysis found small-to-medium effects on anxiety (20 trials) and depressive symptoms (18 trials), but the results varied a lot between studies, so the authors urge caution.
- Who it helps: The analysis found non-significant effects in groups with mental or physical health conditions, and the authors say it could be premature to recommend breathwork there. For people without such conditions, they see slow-paced breathing as low cost and low risk.
- Safety: None of the stress studies reported adverse events directly attributed to breathwork.
- Diaphragmatic breathing: NCCIH cites a 2019 review of 3 studies (880 participants) with preliminary evidence that diaphragmatic breathing may help reduce stress.
In short: breathing techniques are a cheap, low-risk tool that helps many people feel calmer, with real but still limited evidence.
Breathing sessions in the app
Our breathing exercise is for paced breathing with a visual guide. If you'd rather be talked through it, AI Meditation: Sleep & Calm has guided breathing sessions:
- Breath Awareness uses your natural breath as an anchor and adds a few rounds of breathing in for four counts and out for six.
- Breathe Easy is for times when breathing feels hard, for example during a cold, with a calm counted pattern, belly and rib breathing with a hand, and short rounds of gentle breaths. It isn't a treatment for any condition.
- Acute Stress SOS starts with the 4-6 breath for moments when stress hits.
- Letting Go of Stress focuses on long out-breaths and a sigh to release built-up tension.
You can set how long a session lasts within its range, and the voices are AI voices. There's also a daily meditation written by AI after a short mood check-in. See how the app works, try it for free, no account needed.
Your health
This app is a wellness app and does not replace medical advice. Breathing techniques are for relaxation. If you have a heart or lung condition, talk to your doctor before practicing breath holds, and if stress or anxiety last for weeks or affect your day, talk to a doctor. The NHS page Breathing exercises for stress describes a simple, safe starting point.
