How to alleviate side stitches?

To alleviate side stitches, which are often not actual cramps but instead related to the phrenic nerve affecting the diaphragm and nearby organs like the liver, Andrew Huberman recommends utilizing a specific breathing technique known as the physiological sigh. This involves a deep double inhale through the nose followed by a long exhale. Repeating this two to three times while continuing your exercise can change the firing patterns of the phrenic nerve and relieve the pain associated with a side stitch. This method can be performed during various activities like running, swimming, or cycling 1 2.
