The Science Behind It

Box breathing (also known as square breathing) is a nervous system regulation technique used by Navy SEALs, first responders, and elite athletes. By pacing your breath to equal intervals of 4 seconds, you stimulate the vagus nerve and increase parasympathetic activity. This actively down-regulates the sympathetic ('fight-or-flight') nervous system, lowering heart rate, calming blood pressure, and reducing the stress hormone cortisol in under two minutes.
