Diaphragmatic breathing: how to do belly breathing properly

What is diaphragmatic breathing?

It’s slow breathing led by your diaphragm, the dome-shaped muscle under your lungs, rather than your upper chest and shoulders. You’ll also see it called belly breathing or abdominal breathing. They’re the same thing. Your stomach isn’t filling with air: as the diaphragm moves down, it nudges your belly out of the way.

How do you breathe from your diaphragm?

Start lying down, which Cleveland Clinic recommends for beginners:

1. Lie on your backOn a bed or flat surface, knees bent and head supported. A pillow under your knees is fine.
2. Place your handsOne on your upper chest, one just below your rib cage.
3. Breathe in through your noseSlowly. Your lower hand rises and your chest hand stays as still as it can.
4. Breathe out through pursed lipsTighten your stomach muscles gently and let your lower hand fall.

That top hand is your feedback. If it’s the one moving, you’re chest breathing. No drama. Slow down and try again.

How do you do it sitting down?

Same hands, same breath. Sit comfortably with your knees bent and your shoulders, head and neck relaxed. Once it’s easy lying down and sitting, try it at your desk, on the bus or in a queue. No one will notice, and that’s when it starts to be useful.

How long? Start with 5 to 10 minutes, three to four times a day, and build up slowly as it gets easier. If that’s too much for now, one session beats zero. Cleveland Clinic also says you can add a book on your belly later on for extra effort.

What are the common mistakes?

• Pushing your belly out. Let the breath move it. Don’t perform it.
• Lifting your shoulders. If they rise toward your ears, you’ve gone back to chest breathing.
• Taking giant breaths. Slow matters more than big. If you get lightheaded, you’re overdoing it. Stop and breathe normally.
• Waiting until you’re stressed. Learn it when you’re calm, so it’s there when you need it.

What are the benefits of diaphragmatic breathing?

Cleveland Clinic lists helping you relax, lowering heart rate and blood pressure, and reducing the work of breathing, among others. It also says the technique can help with stress, anxiety, asthma and COPD, but that it shouldn’t be the only treatment, and that people with those conditions should check with their provider first.

A fair reading: great as a low-risk way to settle down. Slow breathing is linked in research with calmer body signals, although a 2018 review found the evidence still limited and mixed. Treat bigger claims with caution.

What rhythm should you use?

The classic instructions don’t give you a count, and that’s fine. Some people find a rhythm helps. Pick a pattern where the exhale is at least as long as the inhale. The American Lung Association suggests breathing out for two to three times as long as you breathe in, if you’re practising it with pursed lips.

Common questions

Where does ATHA fit in?

Here’s what ATHA can and can’t do. It can’t see your belly, so the technique is yours. It can keep the rhythm, with a visual, haptic taps, voice cues or optional tones. So your eyes can close, your hands can stay where they are, and you can just notice which one’s moving.
