WHY BREATHING MATTERS Just 5 minutes of intentional breathing can reduce stress, lower blood pressure, and calm your mind. Research shows that consistent daily practice produces measurable improvements in heart rate variability (HRV) and overall well-being. 5 WELL-KNOWN TECHNIQUES • Box Breathing (4-4-4-4) - Used by Navy SEALs for stress relief and focus. Equal inhale, hold, exhale, hold pattern activates your parasympathetic nervous system. • 4-7-8 Breathing - Developed by Dr. Andrew Weil as a "natural tranquilizer." Perfect for sleep preparation and acute anxiety relief. • Diaphragmatic Breathing - The foundation of all breath-work. Strengthens your diaphragm and increases blood oxygen levels. • 2-to-1 Breathing - Extended exhales immediately calm your nervous system.
