Breathing Exercises: Box, 4-7-8, Belly and Cyclic Sighing

Short answer: the simplest breathing exercise is to breathe in gently through your nose, let the breath reach your belly, and breathe out slowly, for at least five minutes (NHS). Slow breathing, under 10 breaths a minute, is linked to relaxation and less anxiety in healthy people (Zaccaro et al.). As of November 2026, the six methods below range from beginner to a bit more structured. Stop if you feel dizzy.

Check with a clinician first. Talk to a doctor before starting if you have asthma, COPD or another lung condition, a heart condition, panic attacks, are pregnant, or often feel light-headed. Do not hold your breath for long, and never practice breathing exercises while driving or in water. If shortness of breath continues, call 911 and seek immediate medical attention (American Lung Association).

What do breathing exercises actually do?

A 2018 systematic review focused on slow breathing, fewer than 10 breaths per minute, in healthy people. It found these techniques increased heart rate variability, shifted brain activity toward more alpha and less theta waves, and were linked to feelings of comfort, relaxation, pleasantness and alertness, along with reduced symptoms of arousal, anxiety, depression, anger and confusion (Zaccaro et al.).

This does not mean breathing replaces treatment for any condition. The review studied healthy volunteers, and techniques differ. What it supports is a modest idea: voluntarily slowing the breath is a reliable way to shift how calm or alert you feel in the moment.

The American Lung Association describes a separate purpose. Pursed-lip and belly breathing are taught by pulmonary rehabilitation specialists to people with asthma or COPD to help slow breathing and manage shortness of breath (ALA). Same tools, different goals, so match the exercise to what you need.

Six breathing exercises at a glance

Exercise	Pattern	Time	Best for
Belly breathing	In through the nose, out slowly, belly rises and falls	5 to 10 minutes	Learning to breathe low and slow
Pursed-lip breathing	In through the nose, out twice as long through pursed lips	A few minutes	Slowing the pace; taught for lung conditions
Box breathing	In 4, hold 4, out 4, hold 4	3 to 5 minutes	A steady, structured count
4-7-8 breathing	In 4, hold 7, out 8	4 rounds	Winding down
Cyclic sighing	Double inhale, long exhale	5 minutes	A quick mood reset
Coherent breathing	About 5 to 7 breaths a minute	5 to 20 minutes	Steady, even pacing

Start with belly breathing. Once it feels natural, try one new pattern per week. The breath coach can pace most of these on screen so you do not need to count.

How to do belly and pursed-lip breathing

Belly breathing. Sit comfortably or lie down and place a hand on your belly. Breathe in slowly through the nose so the belly rises like a balloon. Then breathe out slowly through the mouth, two to three times as long as the inhale if that feels natural. The American Lung Association suggests repeating for 5 to 10 minutes while keeping the neck and shoulders relaxed (ALA).

Pursed-lip breathing. Breathe in through the nose with the mouth closed. Purse the lips as if blowing out a candle and breathe out gently for at least twice as long as the inhale. This slows the pace and keeps the airways open longer.

Practice both when you are breathing comfortably, not first when you are short of breath. The ALA notes the exercises take time to master and are best learned when breathing is okay.

For general calm, the NHS describes a similar approach: breathe gently and regularly, count from 1 to 5 if helpful, let the breath flow out gently, and repeat for at least five minutes (NHS).

Box breathing and 4-7-8

Box breathing uses equal counts: breathe in for four, hold for four, breathe out for four, hold for four. Picture tracing the four sides of a square. If the hold feels uncomfortable, shorten it or skip it and keep the in and out smooth. In a randomized study, a daily five-minute box breathing practice over a month was one of three breathwork exercises compared with mindfulness meditation (Balban et al.).

4-7-8 breathing asks you to breathe in through the nose for four counts, hold for seven and breathe out through the mouth for eight. It was popularized by Dr. Andrew Weil. We cite no trial specific to the 4-7-8 pattern, so treat it as a relaxing habit rather than a proven fix.

The long hold in 4-7-8 is not for everyone. Build up slowly with a shorter ratio such as 3-4-6, stop if you feel dizzy, and check with a clinician if you have a heart or lung condition. The NCCIH advises people new to yoga to avoid forceful breathing (NCCIH).

Cyclic sighing: the best-studied quick reset

In a 2023 randomized, remote study, participants practiced one of three breathwork exercises, or mindfulness meditation, for five minutes a day over one month. Breathwork, especially the exhale-focused cyclic sighing, produced greater improvement in mood and a greater reduction in respiratory rate than mindfulness meditation (Balban et al.). The authors concluded that daily five-minute cyclic sighing has promise as a stress management exercise.

To try it, take a full inhale through the nose, add a short second sip of air to top up the lungs, and then breathe out slowly through the mouth for as long as is comfortable. Repeat for five minutes. Keep everything gentle.

Keep the finding in proportion. It is a single study with a specific design, and the results are about mood and breathing rate, not about treating anxiety disorders. Still, it is among the stronger pieces of evidence for a short daily practice, and it takes no equipment.

Coherent breathing and finding your pace

Coherent or resonance breathing means breathing at a slow, steady rate, often around six breaths per minute. In research on heart rate variability biofeedback, most studies find the largest effects at about 0.1 Hz, which is six breaths per minute (Lehrer and Gevirtz).

The authors also report that the best rate varies by person. Their own work put the average at about 5.5 breaths per minute, and taller people and men tended to have lower resonance frequencies. That is why one-size-fits-all counts can be off.

You can explore your own range with the breath pace finder, which lets you sweep from about 4.5 to 7 breaths per minute and notice which pace feels easiest. It is a way to try rates, not a medical measurement, and nothing is saved. A related breath-hold test is planned as a self-check for curiosity, not a diagnosis.

A simple start: breathe in for five seconds and out for five seconds, which is six breaths per minute, for five minutes.

How to build a daily habit of breathing exercises

Pick one time, such as right after waking or before a meal, and one exercise. Five minutes is enough. Use a timer so you do not need to watch the clock.

Sit with a supported back or lie down. Keep the jaw, shoulders and belly soft. If counting becomes a chore, drop it for a day and just breathe slowly.

Link breathing to movement as well. Many yoga classes use the breath to pace poses, and our beginner guide shows where to start. For help falling asleep, read the yoga for sleep guide. If you want a teacher to coach your breathing in person, browse studios on the Atlanta map once it goes live.

Track how you feel, not how perfectly you counted. A short note on mood before and after a week of practice will tell you more than any number.

Frequently asked questions

What are the best breathing exercises for beginners?

Belly breathing. It is gentle, needs no counting and is the base for the others.

How long should I do breathing exercises?

Five minutes is a good start. The NHS suggests at least five minutes (NHS).

Is it safe to hold my breath?

Short, comfortable holds are common in classes, but long holds are not suitable for everyone. Keep them short and ask a clinician if you have heart or lung conditions.

Can breathing exercises replace medicine?

No. They may help you feel calmer, but they do not replace treatment from a clinician.
