Diaphragmatic breathing (belly breathing): steps, benefits and how to learn it

How to do Diaphragmatic Breathing

1. Lie on your back with your knees bent and feet flat, or sit on a chair with your back supported. Relax your shoulders.
2. Place one hand on your upper chest and the other on your belly, just below the ribs.
3. Breathe in through your nose for 4 counts. Let the belly rise under your hand while the chest hand stays almost still.
4. Breathe out gently for 6 counts through the nose or softly pursed lips. Feel the belly sink back towards the spine.
5. Keep the breath quiet and relaxed. Do not push the belly out or pull it in hard; let it move by itself.
6. Repeat for the 10 rounds on the timer (under 2 minutes), then breathe normally and notice how you feel.

Diaphragmatic breathing, also called belly breathing or abdominal breathing, is breathing mainly with the diaphragm, the dome-shaped muscle under your lungs. When it contracts, it moves down and the belly gently rises; when it relaxes, the belly falls. This page explains what it is, how to use the timer, step-by-step instructions, the benefits of diaphragmatic breathing that research supports, and how to adapt it for kids, pregnancy and after childbirth.

What is diaphragmatic breathing? Meaning and definition

By definition, it means the diaphragm does most of the work of breathing. The belly breathing medical term is diaphragmatic or abdominal breathing. Is diaphragmatic breathing normal? Yes: babies and sleeping adults breathe this way naturally. Many adults lose the habit through stress, tight clothes, poor posture or holding the stomach in, and start to breathe with the upper chest and neck instead.

Diaphragmatic breathing vs belly breathing vs chest breathing

Diaphragmatic breathing vs belly breathing: they are the same technique with two names. The belly is simply where you see the diaphragm move. Belly breathing vs chest breathing is the real contrast: chest breathing is shallow and fast and uses the neck and shoulder muscles, while diaphragmatic breathing is slower and deeper and uses less effort.

How to use the belly breathing timer

The timer uses a 4:6 pattern: 4 seconds in, 6 seconds out, no hold. That is 6 breaths a minute. A slightly longer exhale is the usual diaphragmatic breathing timing for relaxation. The default 10 rounds take 100 seconds; set 30 rounds for 5 minutes. Watch the 3D teacher: her belly rises with the ring as she breathes in.

How to do diaphragmatic breathing correctly

The steps above show the basic belly breathing technique. Health services such as the NHS give out similar diaphragmatic breathing exercises in patient handouts. These tips help you learn how to breathe with your diaphragm:

• Start lying down. Diaphragmatic breathing lying down, with bent knees, is easiest because your back and neck are supported. Then practise diaphragmatic breathing in sitting and, later, standing.
• Use a weight. A light book on the belly shows the movement clearly. Children like a soft toy that "rides" up and down.
• Soften the belly. If you have spent years holding your stomach in, let it go completely while you practise.
• Lengthen the exhale. The diaphragmatic breathing exhale should be relaxed and slow, not forced out.

Why is diaphragmatic breathing hard to learn?

Old habits and tension are the main reasons. If the chest keeps lifting, try lying on your front in Crocodile Pose: the floor stops the chest moving, so you feel the belly and lower back expand. How long does it take to learn diaphragmatic breathing? Most people get the feel of it in a few sessions; making it automatic takes a few weeks of daily practice.

Benefits of diaphragmatic breathing: what research says

Research on the benefits of diaphragmatic breathing is encouraging but mostly based on small studies. The findings suggest these benefits:

Stress, anxiety and panic attacks

Why does diaphragmatic breathing work for stress? Slow breathing with a long exhale is linked with activity of the vagus nerve, which helps the body shift into its rest-and-digest state. Studies suggest it can lower heart rate and self-reported stress. That is why diaphragmatic breathing for anxiety and panic attacks is taught in therapy and in yoga for anxiety.

Digestion, acid reflux, GERD and bloating

The diaphragm helps the valve between the food pipe and stomach stay closed. Small clinical studies found that training diaphragmatic breathing for acid reflux may reduce symptoms, and it is a standard treatment for rumination syndrome and excessive belching. With a hiatal hernia it may help reflux symptoms, but follow your doctor’s plan. See yoga for acidity and acid reflux and yoga for gas and bloating.

Asthma, COPD and blood pressure

Is diaphragmatic breathing good for COPD? Breathing retraining is part of many pulmonary rehab programmes, but in severe COPD a flattened diaphragm can make belly breathing tiring, so learn it from your respiratory team. For asthma, breathing exercises may improve quality of life; keep using your inhaler. Slow breathing may give a small, short-term drop in blood pressure. See yoga for asthma.

Diaphragmatic breathing, pelvic floor, pregnancy and postpartum

The diaphragm and the pelvic floor move together: on the inhale both descend, on the exhale both lift. That is why diaphragmatic breathing for the pelvic floor, including pelvic floor relaxation, is often the first step in physiotherapy. Postpartum, and among the benefits after a C-section, it helps you reconnect with deep core muscles gently. To do diaphragmatic breathing for diastasis recti, breathe into the sides and back of the ribs and, on the exhale, gently draw the lower belly in; avoid strong crunches. See yoga for postpartum recovery and yoga for pelvic floor.

Belly breathing for kids

Belly breathing exercises for kids work best as a game: "smell the flower" for the inhale and "blow out the candle" for the exhale, or imagine the belly as a balloon filling and emptying. Put a toy on the tummy and watch it rise. Three to five breaths are enough for young children. More ideas are on the yoga for kids page.

Diaphragmatic breathing for singers and running

For singers, a relaxed, low inhale lets the voice sit on steady breath support instead of a tight throat. Learning how to belly breathe while running is useful too: practise at rest first, then breathe into the lower ribs and belly on easy runs.

Is diaphragmatic breathing bad? Side effects and dizziness

Diaphragmatic breathing side effects are uncommon. The usual diaphragmatic breathing dizziness causes are breathing too deeply or too fast. Slow down and take in less air. Some people feel a little anxious when first watching the breath; this usually passes with practice.

Diaphragmatic breathing daily practice and in yoga

For diaphragmatic breathing daily practice, try 5 minutes twice a day. The best diaphragmatic breathing exercises for beginners are the simplest: lying down, one hand on the belly, a long exhale. Once that is easy, add it to meditation or combine the belly breath with box breathing on the breathing exercise timer. Take a few belly breaths whenever you notice tension. In yoga, belly breathing is the foundation for Dirga pranayama and other slow techniques.

Breathing practices are safe for most people when done gently. Stop if you feel dizzy, anxious or short of breath, and ask your doctor first if you have heart or lung disease, high blood pressure, epilepsy or are pregnant.
