What is the best breathing exercise for anxiety?

The one with the longest exhale you can manage comfortably. A 2023 Stanford trial compared three breathing patterns with mindfulness meditation for a month and found the physiological sigh, two inhales through the nose followed by one long exhale, gave the largest improvement in mood and the biggest drop in breathing rate. If you have a few minutes rather than a few breaths, a 4-6 calming breath or coherent breathing at five in, five out do the same job more gently.

What is the 3-3-3 rule for anxiety?

A grounding exercise, not a breathing one: name three things you can see, three sounds you can hear, and move three parts of your body. It pulls attention out of the spiral and into the room. It pairs well with breathing: do the 3-3-3 first if your mind is racing, then three physiological sighs to bring the body down with it.

What is the 4-7-8 breathing method?

Inhale through the nose for four counts, hold for seven, exhale through the mouth for eight, and repeat four times. The long exhale and the hold make it the most sedating of the common patterns, which is why it works best in bed and less well before a meeting, where box breathing keeps you alert.

Can anxiety cause breathing problems?

Yes. Anxiety shifts breathing into the upper chest, makes it faster and shallower, and can bring a feeling of not getting enough air, tightness, or a sigh you cannot complete. Over-breathing then lowers carbon dioxide, which causes the tingling and lightheadedness of a panic attack. Slow breathing with a long exhale reverses that within a minute or two. Breathlessness that comes on without anxiety, with chest pain, or that does not settle should be checked by a doctor.

Is 4-7-8 breathing dangerous?

Not for most people, but the seven-second hold can make you lightheaded at first, and it is not the pattern to use mid-panic when you already feel short of air. Start with four cycles, sit or lie down, and shorten the hold if you feel dizzy. If you are pregnant, have a heart or lung condition, or have had fainting episodes, ask your doctor before practising breath holds; the patterns without holds, 4-6 and coherent breathing, are the safe defaults.

How long should you do breathing exercises for anxiety?

For an acute wave, one to three minutes is enough: three physiological sighs take about thirty seconds, and six rounds of 4-6 breathing take one minute. For lasting change, the trials that showed lower anxiety used five minutes a day for four weeks. Short and daily beats long and occasional.

Do breathing exercises help with anxiety at night?

They are the best-suited tool for it, because the racing mind at bedtime is a body still running at daytime speed. Use 4-7-8 or 4-6 breathing lying down, with the lights off, for four to eight rounds. Avoid box breathing at night: it is built to keep you alert.

Breathing exercises for anxiety

Breathe out longer than you breathe in

Anxiety speeds the breath up and pushes it into the chest. Every exercise on this page does the opposite, and each one has a guided timer you can start right now, in your browser, with nothing to install. Pick the one that fits the moment: a wave of panic, a long day, a night you cannot switch off.

Why it works

The exhale is the lever

What anxiety does to your breathing

Under threat the body prepares to move: breathing gets faster, shallower and moves up into the chest. That is useful for running and useless at a desk, and it feeds back on itself. Fast breathing blows off carbon dioxide, low carbon dioxide narrows blood vessels, and the tingling fingers, tight chest and lightheadedness that follow feel like proof that something is wrong. A panic attack is largely that loop running at full speed.

Why a long exhale calms you

Your heart speeds up slightly on every inhale and slows on every exhale. The slowing is driven by the vagus nerve, the main brake of the nervous system, and it is strongest when the out-breath is slow and long. Make the exhale longer than the inhale and you are pressing that brake several times a minute. Slow the whole rhythm to around six breaths a minute and heart rate, blood pressure and the stress response settle together; a 2023 review of breathing practices for stress and anxiety found this effect across most of the patterns studied.

What the trials found

A Stanford study published in Cell Reports Medicine had people do five minutes a day of one of three breathing exercises, or mindfulness meditation, for a month. All four helped. The breathing exercises helped more than meditation, and the one with the longest exhale, the physiological sigh, improved mood most and lowered breathing rate most. The lesson for anxiety is simple: the out-breath does the work, and five minutes a day is enough to change something.

Five exercises

Which one, and when

1
Physiological sigh, 2·1·7: for panic, right now
Breathe in through the nose, then take a second, smaller sip of air on top to fill the lungs fully. Let it all out through the mouth in one long, slow exhale. That is one sigh; one to three is a dose. The double inhale pops open the small air sacs that collapse under shallow breathing, and the long exhale that follows is the fastest way to bring a spike down. It is the exercise for the moment before a conversation, the car park, the bathroom stall. Full guide to the physiological sigh.
2
Calming breath, 4·6: the anxiety reset
Inhale through the nose for four, exhale for six, nothing else. No holds means nothing to get wrong and no chance of feeling short of air, which makes it the pattern to reach for when anxiety is already high and a hold would add to it. Six rounds take one minute. If six feels long, breathe out for five; the point is only that the exhale is longer than the inhale.
3
Box breathing, 4·4·4·4: steady and alert
In for four, hold for four, out for four, hold for four. The even count gives a racing mind one small job to track, and the holds slow the rhythm to about four breaths a minute without making you drowsy. That is why it is taught before exams and hard conversations rather than at bedtime. Four to six rounds. Box breathing timer and guide.
4
Coherent breathing, 5·5: the daily practice
Five seconds in, five seconds out, through the nose, for five minutes. That is six breaths a minute, the rate at which heart rhythm and breathing fall into step and the stress response is quietest. It is not dramatic, which is the point: this is the one to do every day so that the acute exercises above have less work to do.
5
4-7-8 breathing: for the nights
In through the nose for four, hold for seven, out through the mouth for eight, four times. The long hold and longer exhale make it the most sedating pattern here, so it belongs in bed, not before a meeting. If the hold makes you lightheaded, shorten it; the exhale is what matters. 4-7-8 timer and guide.

Start from the belly

Every pattern above works better on a low breath. Put one hand on your chest and one on your stomach, and breathe so that the lower hand moves first and the upper hand barely moves. Anxious breathing lives in the upper chest; moving it down to the diaphragm is half the exercise. If you cannot feel it sitting up, lie on your back with knees bent and it becomes obvious.

During a panic attack

Skip anything with a hold. Do one physiological sigh, then breathe out slowly through pursed lips as if through a straw, and let the inhale take care of itself; the out-breath is the whole job. Count the exhales, not the seconds. The tingling and the pounding heart are the over-breathing loop, and they ease as the exhale lengthens, usually within a minute or two. Breathlessness or chest pain that arrives without anxiety, or does not settle, needs a doctor, not a breathing exercise.

How long, how often

For a wave: thirty seconds to three minutes, whichever exercise fits. For lasting change: five minutes a day, which is the dose that lowered anxiety in the trials, and daily matters more than long. Attach it to something that already happens, the kettle, the commute, the moment you get into bed. The Braele app adds a reminder, a streak with a rest day built in, and haptics you can follow with your eyes closed.
