Why it works

Sama Vritti, meaning "equal fluctuation" in Sanskrit, creates balance by making the inhale and exhale exactly the same length. This symmetry gives the mind a simple, rhythmic anchor that quiets the mental chatter responsible for keeping you awake at night. Neurologically, the steady rhythm entrains brain waves toward alpha and theta frequencies associated with relaxation and the transition to sleep. Research shows that equal-ratio breathing before bed can reduce the time it takes to fall asleep by up to 50%, and regular practice improves overall sleep quality and reduces nighttime awakenings.
