Breathing exercise
Follow an animated circle through scientifically-designed breathing patterns for relaxation, focus, or sleep. Choose from Box Breathing, 4-7-8, Physiological Sigh, and more.
How do I use the Breathing Exercise?
Select a pattern, press Start, and follow the circle. Inhale as it expands, hold steady, exhale as it contracts. The countdown inside the circle shows seconds remaining in each phase. Try to breathe through your nose for inhale and mouth for exhale. Don't force it — if a pattern feels too long, switch to a shorter one or create a custom pattern.
How do Breathing Exercises work?
The 4-7-8 technique (inhale 4 seconds, hold 7, exhale 8) was developed by Dr. Andrew Weil based on pranayama yoga breathing. It activates the parasympathetic nervous system — the body's "rest and digest" response — making it effective for reducing anxiety and falling asleep. Box breathing (4-4-4-4) maintains equal phases and is used by Navy SEALs and first responders to stay calm under extreme pressure. Deep breathing (5-5) is the simplest pattern, good for beginners and general stress relief.
The animated circle serves as a visual anchor: follow its expansion and contraction to maintain rhythm without counting. A subtle tone marks each phase transition. Start with 5-10 rounds and increase as comfortable. For a timed meditation session, use the meditation timer; for background sound during breathing practice, try the white noise generator.
"This breathing exercise is a natural tranquilizer for the nervous system. Unlike tranquilizing drugs, which are often effective when you first take them but then lose their power over time, this exercise is subtle when you first try it but gains in power with repetition and practice."
"The present study illustrates the potential for diaphragmatic breathing practice to improve cognitive performance and reduce negative subjective and physiological consequences of stress in healthy adults."
Breathing Techniques: 4-7-8 vs Box vs Deep Breathing
Each breathing pattern activates different aspects of the nervous system. Choose based on your goal — calming, focus, or energy.

Wim Hof breathing involves breath retention and should not be practiced in water or while driving.
Common Uses
- Pre-exam or presentation anxiety: Two minutes of box breathing before a high-stakes event activates the parasympathetic nervous system, reducing perceived anxiety.
- Workplace stress management: Use the 4-7-8 technique during a bathroom break or at your desk to reset focus during a stressful workday.
- Sleep onset: Slow breathing at 6 breaths per minute primes the body for sleep by lowering heart rate and cortisol levels.
- Athletic performance: Athletes use controlled breathing warm-ups before competition to optimise oxygen intake and mental focus.
- Panic attack management: Diaphragmatic breathing interrupts the hyperventilation cycle common in panic attacks, helping restore calm within minutes.
- Chronic pain relief: Mindful breathing is used alongside physiotherapy and pain management programs to reduce the perception of chronic pain.
- Meditation and mindfulness: A breathing timer provides structure for beginners who find open-ended meditation sessions difficult to sustain.
FAQ
Which breathing pattern is best for anxiety?
The 4-7-8 pattern is specifically designed for relaxation. The long exhale (8 seconds) activates the vagus nerve, slowing heart rate. Start with 4 rounds and work up.
How many rounds should I do?
Start with 4-5 rounds (about 2-3 minutes). For a full session, aim for 10-15 rounds (5-10 minutes). There's no maximum — do as many as feels comfortable.
Can I customise the timing?
Yes, select "Custom" and enter your own inhale, hold, and exhale durations between 1 and 15 seconds each.
Does the breathing exercise tool collect any data?
No. The entire exercise runs locally in your browser. No session data, breathing patterns, or personal information is sent to any server.
How long should a breathing session last?
Even 3–5 minutes of guided breathing can noticeably reduce stress. Most patterns default to cycles you can repeat for 5–10 minutes. Start short and extend as you get comfortable.
By the Numbers
- Slow diaphragmatic breathing at 6 breaths/min can reduce cortisol levels by up to 30% (NIH-published studies)
- Box breathing is used by U.S. Navy SEALs and Special Forces as a tactical stress management technique
- Mindful breathing interventions show significant anxiety reductions in 60–70% of participants across APA meta-analyses
- The 4-7-8 technique was popularized by Dr. Andrew Weil, a Harvard-trained physician and integrative medicine pioneer
