# Breathing exercises for flying: four techniques, step by step

**Short answer:** Slow your breathing and make the out-breath longer than the in-breath. The simplest pattern for a flight is in for 4 seconds, out for 6: six breaths a minute. A "physiological sigh" (two breaths in, one long breath out) helps when a wave of nerves hits, and box breathing gives a racing mind a count to hold. Practice on the ground first. This is information, not medical advice.

## Key facts
- A systematic review of 15 studies linked slow breathing, under 10 breaths a minute, with more comfort, relaxation and alertness, and with less arousal, anxiety and anger. [1]
- In a month-long randomized study, 5 minutes a day of cyclic sighing, a breath with a long exhale, improved mood and lowered breathing rate more than mindfulness meditation did. [2]
- Anxiety fell in every group of that study, including meditation, so the best technique is the one you'll actually use. [2]
- A 2023 meta-analysis of 12 randomized trials with 785 adults found breathwork lowered stress with a small-to-medium effect, but most studies had a moderate risk of bias. [3]
- The NHS breathing exercise counts 1 to 5 on each breath in and out, for at least 5 minutes. [4]
- For 4-7-8 breathing, there is limited clinical research, and lightheadedness is the only reported side effect. [5]

## Why breathing helps on a plane
When you're anxious, your body switches on its stress response: a faster heart, quick shallow breaths, tight muscles. On a plane, a bump or a new noise can set it off before you've had a single thought about it.

Breathing is the one part of that response you can steer on purpose. Slow breathing changes the autonomic nervous system, the body's automatic control system: in the review of 15 studies, it increased heart rate variability, including the natural speeding and slowing of the heartbeat with each breath [1]. And the out-breath seems to matter most: in the 2023 study, the exhale-focused technique brought the biggest improvement in mood [2].

## The four techniques at a glance
| Technique | Pattern | Best moment on a flight | Evidence |
|---|---|---|---|
| **Slow breathing (4-6)** | In 4 seconds, out 6 | Boarding, takeoff, long bumpy stretches | Good: a review of 15 studies [1] and a meta-analysis of breathwork [3] |
| **Physiological sigh** | Two breaths in through the nose, one long breath out | A sudden wave of nerves, a big bump | Some: one randomized study of 108 people [2] |
| **Box breathing** | In 4, hold 4, out 4, hold 4 | When your thoughts race | Limited: tested in the same small study, where the sigh did better on mood [2] |
| **4-7-8 breathing** | In 4, hold 7, out 8 | Settling down on a night flight | Limited clinical research [5] |

## 1. Slow breathing: in for 4, out for 6
Breathing in for 4 seconds and out for 6 takes 10 seconds a breath, or 6 breaths a minute. That's well under the 10 breaths a minute that researchers used to define slow breathing [1].

1. Sit back with your feet flat on the floor and your seat belt fastened. Let your belly move under the belt.
2. Breathe in gently through your nose for a count of 4, letting the breath go down into your belly.
3. Breathe out slowly for a count of 6, through your mouth or nose, without pushing.
4. Keep going for about 5 minutes. The NHS suggests at least 5 minutes for its version [4].

**Try it here:** breathe along with Sora. The circle grows for 4 seconds while you breathe in and shrinks for 6 while you breathe out. Tap the button for full screen and, if you like, soft music.

(On the web page, an animated breathing circle with Sora: it grows for 4 seconds while you breathe in and shrinks for 6 seconds while you breathe out, with the words "Breathe in…" and "…and slowly out" and a countdown.)

If 4 and 6 feel too long, start with what's comfortable. The NHS method counts to 5 in and 5 out and notes you may not reach 5 at first [4]. The longer out-breath matters more than the exact numbers.

## 2. The physiological sigh (cyclic sighing)
This is the technique that did best on mood in the 2023 study [2]: two fills of the lungs, then a long release.

1. Breathe in slowly through your nose.
2. When your lungs feel full, take a second, short breath in through your nose to fill them completely.
3. Breathe out slowly and fully through your mouth, letting the out-breath be the longest part.
4. Repeat. People in the study did this for 5 minutes a day [2].

On a plane, a few rounds when a bump startles you is a gentle place to start, then switch to slow breathing.

## 3. Box breathing
Box breathing gives each part of the breath the same count, which gives a busy mind something to do. Cleveland Clinic describes it this way [6]:

1. Breathe out fully, emptying your lungs.
2. Breathe in through your nose while slowly counting to 4.
3. Hold your breath for a count of 4.
4. Breathe out for a count of 4.
5. Hold again for a count of 4.
6. Repeat for three to four rounds.

Stay at your comfort level and don't strain [6]. If the holds make you feel more anxious, leave them out and simply breathe in for 4 and out for 4 or 6.

## 4. 4-7-8 breathing
This pattern has a long hold and a very long out-breath. Medical News Today, in a medically reviewed article, describes it like this [5]:

1. Rest the tip of your tongue on the ridge just behind your top front teeth.
2. Empty your lungs.
3. Breathe in quietly through your nose for 4 seconds.
4. Hold your breath for 7 seconds.
5. Breathe out through pursed lips for 8 seconds, with a "whoosh" (a quiet one works fine on a plane).
6. Repeat up to 4 times.

If you can't hold your breath that long, use shorter counts in the same ratio [5]. Try it sitting or lying down, since you may feel lightheaded the first few times; if you do, stop or shorten the counts [5].

## Which technique to use, phase by phase
| Moment | Try this |
|---|---|
| At the gate | Slow breathing for 5 minutes, or box breathing to quiet racing thoughts |
| Taxi and takeoff | Slow breathing from the moment you turn onto the runway; count breaths through the climb |
| Turbulence | Breathe out slowly through each bump; a physiological sigh after a big one |
| Descent and landing | Slow breathing from the start of the descent |
| A night flight | 4-7-8 to settle down for sleep |

During turbulence, it helps to know what you're breathing through. For a belted passenger, bumps are uncomfortable rather than dangerous; [is turbulence dangerous?](/guides/is-turbulence-dangerous) explains why. For grounding, muscle relaxation and what to do in a panic attack, see [how to calm anxiety on a plane](/guides/calm-anxiety-on-a-plane).

## Practice on the ground first
Breathing works best when it's a habit, not a new skill you try at 35,000 feet. Practice once or twice a day in the week before you fly, as Cleveland Clinic suggests for box breathing [6]. Pair it with a pre-flight plan from [our tips for nervous flyers](/guides/nervous-flyer-tips).

## Safety: go gently
- **Don't force it.** Stay at a comfortable pace and don't strain [6]. If you feel lightheaded, stop and breathe normally [5].
- **Ask your doctor first** if you have asthma, COPD, a heart condition or another health condition, or if you're pregnant.
- **It's one tool, not a cure.** If fear of flying holds you back, a fear-of-flying course or a professional can help; our [fear of flying guide](/guides/fear-of-flying) explains the options.
- **Keep your seat belt fastened** while you practice, and follow your crew.

## What the evidence says, in plain words
Slow breathing has the most research behind it: a systematic review of 15 studies linked it with feeling calmer and more alert [1]. Breathwork as a whole lowered stress, anxiety and depressive symptoms in a meta-analysis of randomized trials, with small-to-medium effects; the authors warn that most studies had a moderate risk of bias and call for better ones [3]. The cyclic sighing study was small, remote and only a month long, and its participants came mostly from one university class [2]. So: promising, free, gentle and worth trying, but not magic.

## How Sorapuff helps
Sorapuff's breathing ring guides exactly the slow pattern above, in for 4 seconds and out for 6, and on iPhone it can add gentle haptics: a soft swell as you breathe in, one round tap at the top, and a slowing heartbeat-like pulse as you breathe out. The calm button opens it in one tap from the heart tab, a Home Screen quick action, a "Calm me down" shortcut or Control Center. It all works in airplane mode and it's free. It's information and calming tools, not medical advice: always follow your crew.

## FAQ
### What is the best breathing exercise for flying?
Slow breathing with a longer out-breath, such as in for 4 seconds and out for 6, has the most research behind it and is easy to do in a seat. For a sudden wave of nerves, try a physiological sigh: two breaths in through the nose and one long breath out. The best exercise is the one you'll practice before you fly.

### How should I breathe during turbulence?
Breathe out slowly through each bump, letting the out-breath last longer than the in-breath, then return to slow breathing at about 6 breaths a minute. If a big bump startles you, one or two physiological sighs can help. Keep your seat belt fastened and your shoulders loose, and remember that bumps are uncomfortable, not dangerous, for a belted passenger.

### Does box breathing work for flight anxiety?
It may help, especially if counting calms your thoughts, but the evidence is limited. In a small 2023 study, box breathing was one of three techniques tested, and the exhale-focused physiological sigh did better on mood. If the breath holds make you more anxious, drop them and simply breathe in for 4 and out for 6.

### What is the physiological sigh?
It's a breath with two inhales and one long exhale: breathe in through your nose, take a second short breath in to fill your lungs, then breathe out slowly through your mouth. In a 2023 randomized study, 5 minutes a day of this "cyclic sighing" improved mood and lowered breathing rate more than mindfulness meditation.

### Can breathing exercises stop a panic attack on a plane?
They can make it easier to ride out. Slowing your breathing, especially the out-breath, works against the fast, shallow breathing of panic, and gives your mind something to do. A panic attack feels awful but passes. Tell a flight attendant how you feel, and see our guide on calming anxiety on a plane for a step-by-step plan.
