What is Box Breathing (4-4-4-4)?
Box breathing (or square breathing) is a tactical stress-reduction technique famously used by Navy SEALs, emergency responders, and athletes. It consists of 4 equal phases: Inhale for 4s, Hold for 4s, Exhale for 4s, and Hold for 4s to rapidly regulate the autonomic nervous system.
What is the 4-7-8 Relaxation Technique?
Developed by Dr. Andrew Weil, the 4-7-8 breathing pattern serves as a natural tranquilizer for the nervous system. By holding the breath for 7 seconds and executing an extended 8-second exhale, it stimulates the vagus nerve and activates the parasympathetic "rest and digest" response.
How long should a breathing session last?
Practicing for just 2 to 5 minutes (about 4 to 8 cycles) has been clinically shown to lower cortisol, stabilize heart rate, and clear mental fog.
Can I disable the audio chimes?
Yes! The gentle synthesized transition chimes can be muted at any time with the sound toggle button at the top of the exercise.
