Jogging respiration

Jogging makes you exhale more carbon dioxide relative to the oxygen you take in as exercise intensity rises. A double inhale through the nose followed by a long exhale may also relieve a side stitch. 1 2

• Increased intensity and oxygen debt: As exercise intensity rises, CO₂ exhalation increases relative to O₂ intake. At high intensity, your body can accumulate waste that requires extra oxygen afterward, so heavy breathing may continue after you stop to repay that oxygen debt. 3 4
• Side stitch and double inhale: A side stitch is often referred pain linked to the phrenic nerve, which controls the diaphragm and breathing. A deep double inhale followed by a long exhale may change the nerve’s firing patterns and ease the discomfort; repeat it two or three times. 5 6
