Deep breathing exercises modulate the autonomic nervous system by increasing vagal tone and reducing sympathetic arousal. This leads to decreased heart rate, blood pressure, and cortisol levels. Regular practice can improve cardiovascular health, sleep quality, and stress resilience, all contributing to healthy aging and extending healthspan.
Verdict
Highly recommended; simple, free, foundational practice for stress and healthspan.
