It shouldn't be a revolutionary notion: We do it 20,000 times a day. Breathing -- deeply and fully -- is one of our body's fundamental strategies for maintaining well-being. But many of us breathe incorrectly, taking shallow breaths that rob our body and brain of oxygen. The result? We lose our most natural weapon against emotional and physical imbalance. Breathe In, Breathe Out is a step-by-step guide to understanding the healing power of controlled breathing. Drs. Loehr and Migdow explain the physiology of breathing and the ways in which it impacts the body. They catalog the different kinds of breaths individuals can employ to discharge stress and achieve optimal mental and physical performance. They also explore the variety of imbalances that can be countered with controlled breathing: blood pressure, overeating, constipation, headache, chronic pain, injuries, convalescence, asthma, alcohol abuse, hyper-ventilation, sinus congestion, sleep disorders, snoring, sex, and more.
