4-7-8 Breathing Exercise
Falling asleep is preceded by changes in your autonomic nervous system, notably increased para-sympathetic (vagal) activity and reduction of sympathetic drive with a concomitant reduction in heart rate (HR) and increase in heart rate variability (HRV). We can use the breath to activate this response very quickly and efficiently. Vegal activity occurs when we have a longer exhale than inhale. Slow breathing also decreases the HR and increases the HRV. Here's how to do a simple breathing exercise in bed to help you get better quality sleep long-term, called the 4-7-8 Breath. here's how to do it:
