Breathing is the bridge between body and mind, having a profound effect on our physical and psychological functioning. It is, in fact, the most important function in life, and the only one we can perform both unconsciously and consciously. Poor breathing, ie using only your upper chest , can cause symptoms such as dizzy spells, tension, anxiety, constriction in the chest, blurred vision etc. Proper breathing can calm a racing heart and mind, lower blood pressure, soothe the digestive system, allay anxiety, diffuse anger, avert panic, manage pain, promote sound sleep, cope with asthma, and improve your voice. This book includes background information on the respiratory system and its link with the heart and ciculatory system, and exercises to condition the muscles.
