Breathing exercises for anxiety, sleep and stress: six techniques, guided by Bliss

The simplest breathing exercises for anxiety and stress all do one thing: they slow your breathing down and make the breath out longer than the breath in. Anxiety pushes breathing high, fast and shallow. A slow count brings the rate down, and a long exhale gives the calming half of each breath more time. You do not need to be good at it. Two minutes, sitting where you are, is enough to notice a difference.

Below are six techniques. Each one has a short step-by-step guide of its own. Breathing is a calming skill, not a medical intervention: if you have a heart or breathing condition, check with a doctor first, and if you ever feel faint or unwell, stop and breathe normally.

Calm breathing: 4 in, 6 out

Breathe in through your nose for 4 seconds, then out slowly for 6. No holds. That is the whole exercise, and it is the one to start with if you are new to breathing exercises. The breath out is longer than the breath in, and 10 seconds a breath puts you at 6 breaths a minute, the pace most slow-breathing research points to. It works at a desk, in a waiting room or in bed. Calm breathing, step by step.

Resonant breathing: 5.5 in, 5.5 out

Slow and even, with no holds: about 5.5 seconds in and 5.5 seconds out. That is between 5 and 6 breaths a minute, the pace a 2014 review by Lehrer and Gevirtz found gives the largest natural swings in heart rate with each breath. Because nothing changes from one breath to the next, it is easy to keep going for five or ten minutes. Resonant breathing, step by step.

The physiological sigh: in, a little more, long out

Breathe in through your nose, take one more short sip of air on top, then let it all out slowly through your mouth. One or two of these is the fastest reset on this page, and a few minutes of them, called cyclic sighing, is the method that showed the clearest effects in a 2023 randomized study of 108 adults practising 5 minutes a day. The physiological sigh, step by step.

Box breathing: 4-4-4-4

In for 4, hold for 4, out for 4, hold for 4. Four equal sides, like a square. The counting gives a racing mind one simple job, and the two holds are impossible to do while breathing fast. It keeps you calm and alert, which makes it the breath for the ten minutes before a meeting or a hard conversation. If the holds feel uncomfortable, use 3 on every side, or choose a pattern with no holds. Box breathing, step by step.

4-7-8 breathing: for sleep

In through your nose for 4, hold for 7, out through your mouth for 8. Three or four rounds. Each round takes 19 counts, so you breathe only a few times a minute, and the very long exhale leans toward sleep rather than alertness. Cleveland Clinic notes that beginners can feel a little light-headed at first, so count faster if you need to and keep the 4-7-8 shape. 4-7-8 breathing, step by step.

Paced breathing: about 6 breaths a minute

Paced breathing means following a steady count or a cue rather than your own timing, usually at about 6 breaths a minute. Calm breathing and resonant breathing are both paced breathing; the difference is only whether the exhale is longer or equal. The point of a pacer is that you stop counting and simply follow. In CalmSpace.ai the pacer is Bliss's voice in Breathe together, and on Apple Watch there is breathing paced by your heart rate. The NHS's own breathing exercise for stress is a paced breath too: in through the nose, out through the mouth, counting to 5 each way, for at least 5 minutes.

Which breathing technique for which moment?

Any slow breath helps. If you want the best fit, this is how we would choose.

Moment	Try first	Why
Everyday anxiety	Calm breathing (4 in, 6 out)	A longer exhale with nothing to hold; easy to keep up for a few minutes.
The first seconds of panic	Physiological sigh, then a slow breath	Two sighs take the edge off before you can count; then move to 4 in, 6 out.
Sleep	4-7-8 or calm breathing	A long exhale leans toward sleep. Avoid holds if they wake you up.
Before a meeting	Box breathing (4-4-4-4)	Calm but alert; the count gives your mind one job.
With other people	Resonant or calm, in Breathe together	Even rhythms are easiest to share; Bliss paces everyone to one start time.

Deep breathing for anxiety: why the exhale matters

"Take a deep breath" is the advice everyone gives, and it is half right. A big, fast breath in does the opposite of what you want: it leans on the "get ready" side of the nervous system. The calm is in the breath out. Your heart rate rises a little as you breathe in and falls as you breathe out, a normal pattern described in the Lehrer and Gevirtz review. Make the exhale longer and you give the slowing part of every breath more time.

So deep breathing for anxiety is really slow breathing with a long, soft exhale: a comfortable breath in, then let it out like fogging a window. A 2018 systematic review of 15 studies linked breathing slower than 10 breaths a minute with feeling more relaxed and less anxious in healthy people. The authors say the mechanism is still debated, and the studies are small, so the honest summary is: promising, not proven. We wrote more in why a longer exhale calms you down and deep breathing for anxiety.

Breathwork vs breathing exercises: what is the difference?

In plain words, breathwork is the umbrella term and breathing exercises are the simple end of it. Breathwork covers everything from a two-minute slow breath to long, guided sessions that use fast breathing or long holds to produce strong sensations. Those intense forms are best learned in person with a teacher, and they are not what this page is about. The six techniques here are slow, gentle and safe for most people, which is why you can do them at your desk or in bed. If you are curious about the wider field, start with breathwork for beginners, and if you want a quieter practice than breathing, see meditation and mindfulness.

How Bliss guides breathing exercises

CalmSpace.ai is a calm app for iPhone, Apple Watch and the web with Bliss, a voice companion who remembers you. The five rhythms above (Calm, Resonant, Sigh, Box and Sleep) are the five rhythms in Breathe together, which is free. You host a session and share a link. Up to 6 people breathe to one shared start time wherever they are, and the people you invite join from the link in a browser with no account. Bliss can guide everyone with her voice, in sync on every device, so nobody has to count or watch a screen. Rounds last 1, 3, 5 or 10 minutes, and after a round people can send a reaction such as "Feeling calmer" or ask to breathe again.

A weekly circle keeps the same link for the same day and time, for example a family bedtime breath with grandparents in another city, and starts by itself. On an iPhone with an Apple Watch, you can let Bliss notice your heartbeat while you talk; when your heart rate is climbing she slows down and may suggest a breath, and she never says numbers or anything medical. The Apple Watch app also paces your breathing by your heart rate. The library adds 7-day programs for sleep, anxiety and work stress.

Hosting is free: sign up at app.calmspace.ai or get the iPhone app. Read how to breathe with someone far away, and a weekly breathing circle for family far away.
