Cultivate rhythmic breathing along with diaphragmatic breathing for maximum results. Breathing normally happens sixteen to twenty times per minute. Learn to slow this breathing down. Most importantly, slow down the inhalation. A slower inhalation affects nerve centers. Plasma from the capillaries moves more effectively out into the alveoli, picking up oxygen and returning into circulation with the exhale. Lengthening inhalation increases metabolic functions in the air sacs. It also brings more oxygen into the air sacs and then into the bloodstream. It sends an increased blood supply to the alveoli. It also pulls the heart downward toward the abdomen, and as the diaphragm contracts and relaxes, it gives the heart a massage. It also massages the liver and pancreas, improving the functions of the spleen, stomach, small intestine and abdomen in general.
