Complete Guide to Breathing Exercises

8 evidence-based breathing techniques to calm anxiety, reduce stress, and improve wellbeing

Why Breathing Exercises Work

Breathing is the only automatic bodily function that you can also control consciously. This makes it a powerful bridge between your conscious mind and your autonomic nervous system - the system responsible for your stress response.

When you're anxious, your breathing becomes fast and shallow. This triggers your body's alarm system, signaling danger even when you're physically safe. By deliberately slowing and deepening your breath, you can:

What Happens When You Practice Breathing

  • Activate the parasympathetic nervous system (rest and digest mode)
  • Slow your heart rate within seconds
  • Lower blood pressure and reduce cortisol (stress hormone)
  • Increase oxygen to your brain improving clarity and focus
  • Signal safety to your body breaking the anxiety cycle
  • Improve heart rate variability (a marker of resilience)

The beauty of breathing exercises is that they work immediately and you can do them anywhere - no equipment needed, completely free, and they take just minutes.

8 Powerful Breathing Techniques

Master these evidence-based techniques and you'll have a tool for every situation.

Diaphragmatic Breathing

Also known as: Belly Breathing, Deep Breathing

Best for: General anxiety, building breathing awareness, daily practice

The foundation of all breathing exercises. Uses your diaphragm for full, deep breaths that fully oxygenate your body.

How to do it:

  1. 1Sit comfortably or lie on your back
  2. 2Place one hand on your chest and one on your belly
  3. 3Inhale slowly through your nose, letting your belly rise (chest stays relatively still)
  4. 4Exhale slowly through your mouth, feeling your belly fall
  5. 5The hand on your belly should move more than the hand on your chest
  6. 6Continue for 5-10 minutes

💡 Tips: Practice this daily until belly breathing becomes natural. Most people breathe shallowly from their chest, missing out on the calming benefits of deep breathing.

4-7-8 Breathing

Also known as: Relaxing Breath

Best for: Falling asleep, panic attacks, intense anxiety

Developed by Dr. Andrew Weil, this technique is called a "natural tranquilizer for the nervous system."

How to do it:

  1. 1Sit with your back straight
  2. 2Place the tip of your tongue behind your upper front teeth
  3. 3Exhale completely through your mouth (making a whoosh sound)
  4. 4Close your mouth and inhale quietly through your nose for 4 counts
  5. 5Hold your breath for 7 counts
  6. 6Exhale completely through your mouth for 8 counts (whoosh sound)
  7. 7Repeat the cycle 3-4 times

💡 Tips: The ratio is more important than the speed. If holding for 7 is difficult, use a faster count (e.g., count "one-one-thousand" faster). The exhale should take twice as long as the inhale.

Box Breathing

Also known as: Square Breathing, Four-Square Breathing

Best for: Stress management, focus, before presentations or exams

Used by Navy SEALs to stay calm in high-pressure situations. Creates a rhythmic pattern that's easy to remember.

How to do it:

  1. 1Sit upright in a comfortable position
  2. 2Exhale all the air from your lungs
  3. 3Inhale through your nose for 4 counts
  4. 4Hold your breath for 4 counts
  5. 5Exhale through your mouth for 4 counts
  6. 6Hold empty for 4 counts
  7. 7Repeat for 5-10 rounds
  8. 8Visualize tracing a square as you breathe

💡 Tips: If 4 counts feels too short or long, adjust to 3 or 5. The key is equal counts for each phase. This creates a sense of control and predictability.

Alternate Nostril Breathing

Also known as: Nadi Shodhana

Best for: Balancing energy, clearing mind fog, meditation preparation

An ancient yogic technique that balances the left and right hemispheres of the brain, promoting calm and clarity.

How to do it:

  1. 1Sit comfortably with a straight spine
  2. 2Rest your left hand on your lap
  3. 3Bring your right hand to your nose
  4. 4Close your right nostril with your right thumb
  5. 5Inhale slowly through your left nostril
  6. 6Close your left nostril with your ring finger
  7. 7Release your thumb and exhale through your right nostril
  8. 8Inhale through your right nostril
  9. 9Close your right nostril, exhale through your left
  10. 10This is one round - repeat 5-10 times

💡 Tips: Keep your breathing slow and smooth. Don't force it. This technique may feel awkward at first but becomes very natural with practice.

Resonant Breathing

Also known as: Coherent Breathing

Best for: Heart rate variability, vagal tone, overall wellbeing

Breathing at your body's natural resonant frequency (typically 5-6 breaths per minute) to maximize heart rate variability.

How to do it:

  1. 1Sit or lie comfortably
  2. 2Inhale through your nose for 5 counts
  3. 3Exhale through your nose for 5 counts
  4. 4No pauses between breaths - smooth transitions
  5. 5Continue for 10-20 minutes
  6. 6Focus on making each breath smooth and even

💡 Tips: This creates about 5.5-6 breaths per minute. Research shows this rate optimizes heart rate variability, a marker of stress resilience. Try 10-20 minutes daily for maximum benefit.

Counted Breathing

Also known as: 5-2-7 Breathing

Best for: Anxious thoughts, rumination, panic

Gives your mind a simple task (counting) which interrupts anxious thought patterns.

How to do it:

  1. 1Sit comfortably and close your eyes
  2. 2Inhale through your nose for 5 counts
  3. 3Hold for 2 counts
  4. 4Exhale through your mouth for 7 counts
  5. 5Repeat 10-15 times
  6. 6If your mind wanders, gently return to counting

💡 Tips: The longer exhale (7 counts) activates your parasympathetic nervous system. Counting gives your mind something to focus on besides anxious thoughts.

Pursed Lip Breathing

Best for: Shortness of breath, panic attacks, controlling breathing pace

Slows down your breathing and keeps airways open longer, making each breath more effective.

How to do it:

  1. 1Relax your neck and shoulders
  2. 2Inhale slowly through your nose for 2 counts
  3. 3Purse your lips as if you're whistling or blowing out a candle
  4. 4Exhale slowly through pursed lips for 4 counts
  5. 5Repeat for several minutes

💡 Tips: The exhale should be twice as long as the inhale. This technique is especially helpful during exercise or when feeling short of breath from anxiety.

Physiological Sigh

Also known as: Double Inhale

Best for: Quick stress relief, resetting nervous system, between tasks

A natural mechanism your body uses to expel CO2 and reduce stress. Takes only seconds.

How to do it:

  1. 1Take a deep breath in through your nose
  2. 2At the top, take a second quick inhale (a little "sip" of air)
  3. 3Exhale slowly and fully through your mouth
  4. 4That's it - one complete physiological sigh
  5. 5Repeat 1-3 times for quick relief

💡 Tips: This is the fastest way to reduce your stress level. Research from Stanford shows just 1-3 physiological sighs can noticeably calm you. Your body does this naturally throughout the day.

Common Mistakes to Avoid

Trying too hard

Breathing exercises should feel natural and relaxing, not forced. If you feel dizzy or lightheaded, you're trying too hard. Slow down and breathe more gently.

Only using during crisis

Practice when you're calm so the techniques become automatic. Trying to learn a new breathing pattern during a panic attack is much harder.

Chest breathing instead of belly breathing

Most breathing techniques work best with diaphragmatic (belly) breathing. Your belly should expand on the inhale, chest relatively still.

Giving up too soon

If one technique doesn't work, try another. Different techniques work for different people and situations. Experiment to find your favorites.

Building a Daily Practice

To get the most benefit from breathing exercises, make them part of your daily routine:

Sample Daily Routine

  • Morning:5 minutes of diaphragmatic breathing to start your day calm and centered
  • Midday:2-3 physiological sighs between tasks to reset
  • Evening:10 minutes of resonant breathing or 4-7-8 to wind down before bed
  • As needed:Box breathing before stressful events, pursed lip for panic
Start small: Even 2 minutes of breathing practice daily is beneficial. Once it becomes a habit, you can gradually increase the duration.

Combine Breathing with Complete CBT

Breathing exercises are powerful, but they're even more effective when combined with cognitive restructuring, exposure therapy, and other evidence-based anxiety treatments.
