A Tranquil Space to Restore Your Breath
Why 4-7-8 Breathing?
Developed by Dr. Andrew Weil, the 4-7-8 breathing technique acts as a natural tranquilizer for the nervous system. Inhale for 4 seconds, hold for 7, and exhale for 8. The extended exhale triggers the vagus nerve to slow your heart rate, cutting through anxiety and panic. This free PWA tool requires no signup, collects no data, and works offline.
Why Box Breathing?
Box breathing (4-4-4-4) is used by Navy SEALs and first responders to restore clarity under extreme pressure. Each phase — inhale, hold, exhale, hold — lasts 4 seconds, creating a steady rhythm that resets your nervous system and sharpens focus. Practiced daily, it builds resilience against stress and improves sleep quality.
