Deep BreathingAlso, chronic stress has been found to delay wound healing, to promote atherosclerosis, and possibly has detrimental effect on parts of the brain involved in learning, memory, and mood. Deep breathing works by aiding in lowering the concentration of the stress hormones cortisol and norepinephrine and reducing the other signs of stress in the body. Other relaxation methods include meditation, yoga, and Tai Chi. To use the method some use the following Prevention magazine technique: Exhale strongly through the mouth, making a whoosh sound. Breathe in quietly through the nose for a count of 4. Hold your breath for a count of 7; then exhale with the whoosh sound for a count of 8. Repeat the cycle three more times. Since 2002 (when the Food and Drug Administration cleared it), there has also been a nonprescription medical device called RESPeRATE available for aiding in deep breathing exercises. The device counts breaths by sensing chest or abdominal movement, and sounds gradually slowing chimes that signal when to inhale and exhale. The users then follow the tone until their breathing slows from the usual 16 to 19 breaths a minute to 10 or fewer.
