why does my diapham tighten up when i exhale
Prevent Side Stitches. Belly breathing can prevent those annoying spasms we call side stitches. Side stitches are muscle spasms of the diaphragm. The diaphragm, which serves as a buffer between the organs in your abdomen and the organs in your chest cavity, moves up when you exhale and down when you inhale.t also means they're exhaling more carbon dioxide and breathing in more oxygen. When you breathe normally, the lungs expand on the inhale and compress on the exhale. With belly breathing, you use your diaphragm to help push as much air out of the lungs as possible, allowing more fresh air to come in.
