Deep breathing for anxiety usually means slow diaphragmatic, or belly, breathing: a gentle breath in through the nose that lets your belly rise, then a longer, unhurried breath out. "Deep" refers to where the breath moves, not how much air you take. Try a few comfortable breaths with the no-hold timer below, and stop whenever you want.

Guided practice

Breathe along

Breathe in for about 5.5 seconds and out for about 5.5 seconds — roughly five and a half breaths a minute.

How to do deep belly breathing

  1. Sit with your back supported, or lie on your back with your knees bent. Let your shoulders drop.
  2. Rest one hand on your upper chest and the other just below your ribs.
  3. Breathe in gently through your nose. Let the lower hand rise as your belly softens outward; the upper hand stays fairly still.
  4. Breathe out slowly through your nose or softly pursed lips. Let the belly fall back without pushing.
  5. Keep each breath small enough that you never feel strained or short of air. A slightly longer exhale than inhale is a common starting point.
  6. Repeat for one to three minutes, then return to your usual breathing and notice how you feel.

The timer above uses coherent breathing, an even rhythm of about 5.5 seconds in and 5.5 seconds out with no breath holds. That pace may feel slow at first. You can follow it loosely, breathe at your own pace with your hands as the guide, or stop the timer and keep only the belly movement.

If you would rather watch your breath than change it, try mindful breathing instead.

Deep breathing is not big breathing

A common mistake is to take the largest breath you can. Pulling in a lot of air quickly, again and again, can leave you lightheaded, tingly or more on edge, the opposite of what most people want. Aim for breaths that are slow and low, not large. If you notice yourself gulping or lifting your shoulders, make the next breath smaller and let the exhale take its time.

It is also normal for belly breathing to feel awkward. Many adults breathe mostly into the upper chest during the day. Practicing lying down, when the belly moves more easily, can help you learn the feeling before trying it seated.

When to use it

Deep breathing is easiest to learn when you are already fairly calm: a quiet break, after closing your laptop, or as part of a wind-down routine before bed. Once the movement is familiar, some people use a few slow belly breaths before a stressful conversation or while waiting for an appointment.

If you prefer a counted structure, box breathing adds equal pauses, and 4-7-8 breathing uses a longer hold and exhale. Both include breath holds, which not everyone finds comfortable. When focusing on the breath makes you more aware of anxious sensations, an outward focus such as 5-4-3-2-1 grounding may suit you better. The breathing exercises guide compares all of the options.

Who should be careful

Stop and return to normal breathing if you feel dizzy, lightheaded, tingly, short of breath or more distressed. Do not practice while driving, swimming or doing anything that needs your full attention.

If you are pregnant, or have asthma, COPD, a heart or lung condition, or a history of fainting, keep sessions short and gentle and ask a qualified clinician which breathing exercises suit you. Breathing retraining for a lung condition is a medical treatment that should be guided individually, not replaced by a web timer. New or severe shortness of breath, chest pain or breathing difficulty needs prompt medical attention.

The breathing for panic attacks guide explains gentler steps without holds and when to get medical help. During a panic attack, slow breathing may help some people ride out the wave, but it can feel hard to do in the moment. Practicing at calm times first makes it more familiar. If panic attacks are frequent or worsening, talk with a doctor or mental health professional.

What the research says

A 2017 randomized study of 40 healthy adults gave one group 20 sessions of diaphragmatic breathing training over eight weeks at about four breaths per minute, using a real-time feedback device. Compared with their starting point, trained participants reported less negative affect, showed better sustained attention and had lower cortisol levels, while the control group's cortisol did not change. This was a small study with intensive, guided training, so it does not show what a few minutes of unassisted practice will do.

A 2019 systematic review found only three studies that tested diaphragmatic breathing on its own for stress in adults. Each reported some improvement, in measures such as cortisol, blood pressure or self-rated stress, but the studies were small and too different to combine.

A 2023 meta-analysis of 12 randomized trials with 785 adults found that breathwork in general was associated with lower self-reported stress than control conditions, a small-to-medium effect, with similar effects for self-reported anxiety. The authors rated most studies at moderate risk of bias and urged caution against hype. Together, these findings make slow breathing a reasonable thing to try, not a promised result.

Common questions

Does deep breathing help with anxiety?

Some studies of slow and diaphragmatic breathing report lower self-rated stress and anxiety, but they are mostly small and use repeated, guided practice. Many people find a few slow belly breaths helpful in the moment; others notice little change. If anxiety is frequent or affects daily life, discuss it with a qualified professional.

What is the difference between deep breathing and diaphragmatic breathing?

In everyday use they mean the same thing: slow breathing that moves the belly more than the upper chest. Diaphragmatic breathing is the more precise name, because the diaphragm is the main muscle doing the work. Neither means taking the biggest breath you can.

Can deep breathing help me fall asleep?

Slow, gentle breathing is a common part of a wind-down routine, and lying on your back is a comfortable way to practice belly breathing. It will not help every night or for everyone. The deep breathing for sleep guide adapts the steps for bedtime. If you regularly struggle to fall or stay asleep, a doctor can help look at the cause.

How many deep breaths should I take?

There is no set number. Start with three to five slow breaths and see how you feel. One to three minutes is a manageable session; stop sooner if you feel lightheaded or uncomfortable.

Can deep breathing stop a panic attack?

It may help some people feel steadier during a panic attack, especially if they have practiced at calmer times, but it does not stop every attack and can feel difficult in the moment. Keep breaths small and slow rather than large. If panic attacks keep happening, seek support from a doctor or mental health professional.
