• Pain during run breathing

  • Sources:

    Experiencing pain while breathing during running, often referred to as a "side stitch," is commonly misunderstood. According to , this discomfort is not typically due to a muscle cramp but rather involves the phrenic nerve, which affects the diaphragm and the liver. This condition is often linked to improper breathing technique while exercising 1.

    To relieve this pain, recommends a specific breathing technique known as the "physiological sigh," which involves a double inhale through the nose followed by a long exhale. Performing this two or three times can alter the nerve's firing patterns and alleviate the discomfort. This technique can be conducted while still engaging in physical activity, such as running or swimming 1 2.

    Breathing deeply and correctly during exercise can help manage and prevent these side stitches, ensuring better performance and less discomfort 3.
