ONE of the most important factors in building and maintaining good health is to breathe deeply. Several times daily stop and deliberately take half a dozen or more deep breaths. Inhale through your nose, and at the same time expand your abdomen and chest to their fullest extent. Exhale through your mouth, slowly, smoothly, deeply.
Realize that deep breathing cleanses your lungs and fills them with life-given oxygen. Enjoy the exercise and get the full benefit of its invigorating effect. Deep breathing is the basis of robust health.
Remind yourself many times daily to breathe deeply, and continue this practice until it becomes an unconscious habit. The last thing at night take several deep breaths at an open window.
