Most adults breathe shallowly, using mostly the chest. Diaphragmatic breathing — using the diaphragm to draw air into the lower part of the lungs — triggers a measurable relaxation response and underlies almost every serious stress-management technique.
How to know if you breathe shallowly
Place one hand on your chest and the other on your abdomen. If the hand on your chest moves more than the one on your abdomen as you breathe, you're likely breathing shallowly most of the day.
Step-by-step practice
- Sit or lie down with your back supported.
- Place one hand on your chest and one on your abdomen.
- Inhale slowly through your nose, letting your abdomen expand; your chest should barely move.
- Exhale slowly through your mouth, noticing your abdomen fall.
- Repeat for 3 to 5 minutes, without forcing the pace.
5-second pause. Inhale… hold… exhale slowly. Let's keep reading.
Why it works
This type of breathing stimulates the vagus nerve, which helps activate the parasympathetic nervous system — the "rest and digest" mode — and counteracts the sympathetic activation linked to stress. With regular practice, some people notice their baseline breathing, even without thinking about it, becomes deeper over time.
When to practice it
It works both as a preventive practice (a few minutes a day) and as an emergency tool during moments of acute tension. It requires no equipment or prior training, which makes it easy to sustain long term.
