Health and Deep breathing
Deep breathing exercises are intended especially to develop greater lung capacity and to assist in forming the habit of breathing deeply and properly at all times.
The respiratory organs are developed nicely through deep breathing. It puts in extra oxygen into the blood and, therefore, secures richer tonic for the blood. This means an offer of richer materials to the tissues to consume.
The whole work of metabolism ultimately depends upon the oxygen you breathe into the lungs. The more deeply and properly you breathe, the better is the oxygen supply, the better is the body able to carry on its work and the better is your health, as a direct consequence.
Deep breathing brings into the lungs a greater volume of air that is required to dilute the carbon dioxide produced in the body during the time.
