Diaphragmatic breathing using the lower part of your lungs is one of the best ways to lower stress in the body. This is because when you breathe deeply, it sends a message to your brain to calm down and relax. The brain then sends this message to your body. The diaphragm is the most efficient muscle of breathing. It is a large, dome-shaped muscle located at the base of the lungs. Your abdominal muscles help move the diaphragm and give you more power to empty your lungs.
