Get rid of a side stitch when running: Exhale as your left foot hits the ground.
If you’ve ever experienced a common side stitch while exercising, you probably tried many different things to get rid of the uncomfortable feeling. You can avoid interruption just by controlling your breathing throughout your activity.
While you are running, be mindful of the breaths you take as your foot hits the ground. Time your breaths so that you exhale as your left foot hits the ground.
This might take some practice because people tend to exhale as their right foot hits the ground. But that puts downward pressure on your liver (which sits on the right side of your body), which then tugs at the diaphragm, creating the sensation of a side stitch.
Inhaling as your right foot hits the ground instead expands your rib cage, releasing pressure on your diaphragm. So, remember: Right, Inhale – Left, Exhale.
A side stitch is usually nothing to worry about and will go away on its own. But if the pain doesn’t go away, radiates to another area or comes with shortness of breath, it could be heart or lung related. Call 9-1-1 or seek immediate medical attention.
