Breathing Techniques
Five approaches, each designed for a different goal.
Calm — 4·6
Inhale for 4 seconds, exhale for 6. The longer exhale activates the parasympathetic nervous system, making this the go-to technique for everyday stress relief and winding down.
Box — 4·4·4·4
Inhale 4, hold 4, exhale 4, hold 4. Equal phases create a steady rhythm used by Navy SEALs and high-performance athletes to stay calm and focused under pressure.
4-7-8
Inhale 4, hold 7, exhale 8. Developed by Dr. Andrew Weil, this pattern is one of the most popular techniques for falling asleep faster and calming an anxious mind quickly.
Physiological Sigh
Double inhale through the nose followed by a long, slow exhale. Researched at Stanford, this is the fastest known way to reduce physiological stress in real time — one or two cycles is often all it takes.
Coherence — 5·5
Inhale 5, exhale 5. This 6 breaths-per-minute pattern maximizes heart rate variability (HRV), strengthening the link between heart and brain and building resilience over time.
