Belly Breathing: Diaphragmatic Breathing Exercises
The foundation of all breathwork—learn to breathe from your diaphragm.
Last updated: February 3, 2026 • Reviewed by Resonance Editorial Review Team
Technique overview
What it is
Belly breathing means using your diaphragm—not your chest and shoulders—to drive respiration. When you inhale, your diaphragm contracts and moves downward, creating a vacuum that pulls air into your lungs. Your belly expands outward. When you exhale, the diaphragm relaxes, pushing air out as your belly falls. The timing is 4 seconds in, 6 seconds out, with no holds.
Belly Breathing vs Diaphragmatic Breathing
Belly breathing and diaphragmatic breathing are the same technique. 'Belly breathing' describes the visible belly rise; 'diaphragmatic breathing' describes the muscle doing the work. If your belly expands while your chest stays quiet, you're doing it right.
Why it matters
Most adults have shifted to shallow chest breathing—especially under stress. Chest breathing uses accessory muscles (shoulders, neck) inefficiently and can perpetuate anxiety. Diaphragmatic breathing is how you breathed as a baby and how you breathe during deep sleep. Relearning this pattern can reduce stress, improve oxygen efficiency, and support better sleep.
Benefits
Deep diaphragmatic breaths stimulate the vagus nerve, activating the parasympathetic 'rest and digest' response. Studies show regular practice can lower cortisol, reduce blood pressure, improve heart rate variability, and decrease anxiety. It's also the foundation for singing, public speaking, and athletic performance.
When to use
Anytime you want to calm down, before bed, during stress, or when learning any other breathing technique. This is the 'default' healthy breathing pattern—ideally, your normal breathing should look like gentle belly breathing.
When to skip
Belly breathing is safe for almost everyone. However, if you have a hiatal hernia, recent abdominal surgery, or severe respiratory conditions, consult your doctor first. Stop if you feel any pain or unusual discomfort.
Belly Breathing vs Chest Breathing
Most adults unknowingly breathe from their chest—shallow, rapid breaths that use shoulder and neck muscles. This pattern is inefficient and associated with chronic stress. Belly breathing (diaphragmatic breathing) uses your primary breathing muscle, is how you breathed as a baby, and is how you breathe during sleep. Quick test: place one hand on your chest, one on your belly. Breathe normally. If your chest hand rises more than your belly hand, you're chest breathing and could benefit from retraining. The goal isn't to force deep breaths—it's to let your belly do the work naturally.
Step-by-step
How to practice
Structured walkthrough pulled from the editorial brief.
- Total time
- 5–10 minutes
- Difficulty
- easy
- Tools
- Comfortable surface to lie on (bed, yoga mat), On-screen timer (optional)
- 1
Get comfortable
Lie on your back with knees bent, or sit in a comfortable chair. Loosen any tight clothing around your waist.
30 seconds
- 2
Place your hands
Put one hand on your upper chest and one on your belly, just below your ribcage. This helps you feel where the breath is going.
10 seconds
- 3
Exhale completely
Before starting, exhale fully through your mouth to empty your lungs. Let your belly fall inward.
3-4 seconds
- 4
Inhale into your belly
Breathe in slowly through your nose for 4 counts. Focus on pushing your belly hand upward while keeping your chest hand still. Imagine inflating a balloon in your abdomen.
4 seconds
- 5
Exhale slowly
Breathe out through your nose (or pursed lips) for 6 counts. Feel your belly fall as the diaphragm relaxes. Keep the exhale smooth and controlled.
6 seconds
- 6
Repeat and relax
Continue for 5-10 minutes, keeping the rhythm smooth. If your mind wanders, gently return attention to the belly rising and falling.
5–10 minutes
Use cases
Where it fits
Situations where this breathing cadence excels.
Stress relief
Use anytime you feel stressed or overwhelmed to quickly activate your relaxation response.
2-5 minutes, several times daily
Sleep preparation
Practice in bed to calm your nervous system and prepare for sleep.
5-10 minutes before sleep
Breathwork foundation
Master belly breathing before moving to other techniques—it's the base for everything.
Daily practice until it becomes automatic
Suggested frequency
Daily, 5-10 minutes. Ideally becomes your default breathing pattern.
Practice notes
Keep it gentle
Helpful reminders so the pattern stays sustainable day after day.
Hand placement helps
Place one hand on your chest, one on your belly. Only the belly hand should rise. The chest stays relatively still.
Start lying down
It's easiest to feel your diaphragm when lying on your back. Gravity helps the belly rise naturally.
Keep it gentle
Don't force a big belly expansion. The movement should be smooth and comfortable, not exaggerated.
FAQ
Common questions
Evidence-backed answers we hear from practitioners most often.
What's the difference between belly breathing and diaphragmatic breathing?
They're the same thing. 'Belly breathing' describes what you see (belly moving), while 'diaphragmatic breathing' describes what's happening anatomically (diaphragm contracting). Both terms refer to using your primary breathing muscle—the diaphragm—rather than accessory muscles in your chest and shoulders.
How do I know if I'm breathing from my diaphragm?
Place one hand on your chest and one on your belly. When you inhale, your belly should expand outward while your chest stays relatively still. If your shoulders rise and chest expands but belly doesn't move much, you're chest breathing. Most people need to consciously relearn belly breathing after years of shallow habits.
Why is belly breathing better than chest breathing?
The diaphragm is designed to power breathing efficiently. Chest breathing uses smaller accessory muscles (shoulders, neck, intercostals) that fatigue more easily and are associated with stress responses. Diaphragmatic breathing takes deeper breaths with less effort, stimulates the vagus nerve for relaxation, and is how humans naturally breathe when relaxed or sleeping.
Can belly breathing help with anxiety?
Yes, significantly. Deep diaphragmatic breaths stimulate the vagus nerve, which activates the parasympathetic nervous system—your body's 'brake pedal' that counters the fight-or-flight stress response. Studies show regular practice reduces cortisol levels and self-reported anxiety. It's often the first technique taught in anxiety management programs.
How often should I practice belly breathing?
Ideally, 5-10 minutes daily to retrain your default breathing pattern. Many people set reminders to do 1-2 minutes several times throughout the day. Over time, diaphragmatic breathing should become your natural default—you won't need to think about it.
Is belly breathing good for sleep?
Excellent for sleep. Practice for 5-10 minutes in bed before sleep to activate your relaxation response. The slow, rhythmic pattern (4 seconds in, 6 seconds out) naturally slows your heart rate and prepares your body for rest. Many people find they fall asleep before finishing their practice.
Research & safety
What evidence says
Peer-reviewed highlights and guardrails pulled from the content brief.
Study highlights
Diaphragmatic breathing reduces cortisol
A 2017 study found 8 weeks of diaphragmatic breathing training significantly reduced cortisol levels and self-reported stress in healthy adults.
Effects on autonomic function
Research shows diaphragmatic breathing shifts autonomic balance toward parasympathetic dominance, improving heart rate variability and reducing blood pressure.
Diaphragmatic breathing and anxiety
Multiple studies demonstrate significant reductions in anxiety symptoms with regular diaphragmatic breathing practice, often comparable to medication effects.
Safety notes
- Belly breathing is safe for most people—it's how you're designed to breathe.
- If you have recent abdominal surgery, consult your doctor before deep breathing exercises.
- Stop if you feel pain, dizziness, or unusual discomfort.
- Those with severe respiratory conditions should consult a healthcare provider.
