WHY BREATHING EXERCISES WORK
Breathwork activates your parasympathetic nervous system — the "rest and digest" response that counters stress and anxiety. Even 2-5 minutes of guided 4-7-8 breathing or box breathing can measurably lower heart rate, reduce cortisol, and improve focus. That's why Navy SEALs use box breathing, and why Stanford researchers recommend the physiological sigh.
