Breathing exercises for health Breathing exercises for health Breathing is one of the most natural and healthful functions of the body. The inhalation of oxygen creates the beginning of an exchange as the gas moves into the millions of alveoli in the lungs, then on to the blood in the surrounding capillaries where it moves carbon dioxide from the blood to the alveoli.
Breathing is, in most case, automatic.
The brain and small sensory organs signal when oxygen levels are too low or carbon dioxide levels are too high. In response to this signal, the brain increases the speed and depth of breathing. Deep breathing exercises have been used for years as a way of relaxing the body. Anyone who has ever noticed how an infant's abdomen rises and falls with each breath has experienced the art of proper deep breathing. Most adults today tend to fill only the upper chest when they breathe and thus miss how the increased oxygen intake relieves tension and improves metal alertness.
