Weils: 4-7-8 Breathing Exercise
Andrew Weil, M.D.
Developed by Dr. Andrew Weil and dubbed by him as “natural tranquilizer for the nervous system”, this breathing exercise was adopted also from the yogic practice of Pranayama (formal control of breathing). Dr. Andrew Weil designed this breathing exercise to aid with sleep by lulling one’s body into a state of deep relaxation. Citing two studies: one by the Journal of Clinical & Diagnostic Research and the other by National Centre of Health, Dr. Weils argues that this adapted Pranayama breathing exercise can help induce a calm state which as a result has the potential to aid one with sleep. Below are the additional links to Dr. Weil’s cited research, an honest review from a Refinary29 on the effectiveness of the 4-7-8 breathing method article, and two videos of Dr. Weil explaining his 4-7-8 breathing method.
