How breath-control can change your life: a systematic review on psycho-physiological correlates of slow breathing
Zaccaro et al., 2018 · Frontiers in Human Neuroscience
What they found
Breathing slower than about 10 breaths a minute was linked to greater heart-rate variability, relaxation and alertness, and lower anxiety and anger.
Limits
The studies were few, small and varied in method, so the size of the effect is uncertain.
How we use it
The breath while your journey loads, and short practices each morning.
