5 Breathing Exercises to Instantly Reduce Stress and Anxiety

If you’re feeling overwhelmed, anxious, or stressed, your breath is one of the most powerful tools you have to restore calm. Science confirms that controlled breathing can lower cortisol (the stress hormone), activate the parasympathetic nervous system, and reduce symptoms of anxiety and panic (Harvard Medical School).

In this guide, we’ll explore the best breathing techniques for stress relief, anxiety reduction, and nervous system regulation. Whether you’re experiencing an anxiety attack or just need to reset, these exercises will help you feel more in control within minutes.

1. Box Breathing (The Navy SEAL Technique)

Best for: Immediate stress relief, focus, and calming the nervous system.

Box breathing, also known as square breathing, is a technique used by Navy SEALs to stay calm under pressure. It regulates oxygen intake and slows the heart rate, making it highly effective for reducing anxiety fast.

How to do it:

1. Inhale through your nose for 4 seconds.

2. Hold your breath for 4 seconds.

3. Exhale slowly through your mouth for 4 seconds.

4. Hold again for 4 seconds.

5. Repeat for 1-2 minutes or until you feel calmer.

   
   

2. 4-7-8 Breathing (The Relaxation Breath)

Best for: Quickly lowering anxiety, improving sleep, and relaxing the body.

Developed by Dr. Andrew Weil, this breathing technique slows down the heart rate and increases oxygen flow to the brain. It has been shown to reduce cortisol levels and improve sleep quality (National Institutes of Health).

How to do it:

1. Inhale deeply through your nose for 4 seconds.

2. Hold your breath for 7 seconds.

3. Exhale slowly and completely through your mouth for 8 seconds.

4. Repeat for 3-5 cycles.

This method helps to calm the nervous system, making it especially useful for panic attacks and bedtime anxiety.

3. Diaphragmatic Breathing (Belly Breathing)

Best for: Long-term anxiety relief, resetting the nervous system, and improving lung capacity.

Also called abdominal breathing, this technique engages the diaphragm to promote deep, slow breathing, which is proven to activate the body’s relaxation response (Cleveland Clinic).

How to do it:

1. Place one hand on your chest and one on your belly.

2. Inhale deeply through your nose, expanding your belly (not your chest).

3. Exhale slowly through your mouth, pulling your belly inward.

4. Repeat for 5 minutes to fully relax.

   
   

4. Alternate Nostril Breathing (Nadi Shodhana)

Best for: Balancing emotions, clearing the mind, and relieving stress.

A technique rooted in yogic breathing (pranayama), alternate nostril breathing balances the left and right hemispheres of the brain, bringing mental clarity and emotional stability (National Library of Medicine).

How to do it:

1. Close your right nostril with your thumb and inhale through your left nostril.

2. Close your left nostril with your ring finger, exhale through your right nostril.

3. Inhale through your right nostril, then switch and exhale through your left nostril.

4. Repeat for 1-3 minutes for immediate relaxation.

5. The Physiological Sigh (Double Inhale Exhale)

Best for: Rapidly reducing stress, resetting the nervous system, and improving oxygen flow.

A method discovered by Stanford neuroscientists, the physiological sigh is a natural reflex the body uses to relieve stress and optimize breathing.

How to do it:

1. Take a deep inhale through the nose.

2. Just before reaching full lung capacity, inhale again (a smaller second breath).

3. Exhale slowly through the mouth.

4. Repeat 3-5 times for an immediate calming effect.
