This document summarizes two breathing exercises recommended by Dr. Lisa M. Cannon to help improve sleep. The first is diaphragmatic breathing, where one observes the stomach rising before exhaling to slow breathing and calm the body. The second is alternate nostril breathing while seated, where one inhales through one nostril and exhales through the other for five minutes to release tension and wind down the body. Dr. Cannon notes that simple breathing exercises can calm both the body and mind by normalizing breathing and preparing the body for sleep, as sleeping disorders are often caused by stress and anxiety.
