BLOG 327 YAWNING

Mouth open wide, a loud sigh, and the face stretched to its capacity. We yawn involuntarily, but why do we seem to do it so much during exercise?? I just thought I was boring you.

When we are tired we yawn, so naturally as the body becomes fatigued from exercise, we then start to yawn. According to Livestrong.com (2013), yawning helps to cool down the brain during exercise. Furthermore, in order to cool down our body temperature, our initial reaction is to sweat. If sweating isn’t enough to cool us down, we then start to yawn which, “increases blood flow and heart rate and enables the intake of cool air, all of which may help regulate your brain’s temperature” (http://www.livestrong.com/article/424772-why-do-you-yawn-when-you-exercise/). Yawing brings in oxygen which then can be brought to the blood. During exercise our blood flow is increased, so we require more oxygen to the blood during activity. You will also be happy to know that the abdominal muscles are used during yawing.

The body is undergoing a behavioral change when we workout, so exercise takes us from a normal to more awake state, which then causes yawing. There are other theories as well that might align with why we yawn at the studio or in a gym setting. According to an article by Melanie Radzicki McManus, “Our bodies induce yawning to draw in more oxygen or remove a buildup of carbon dioxide. This theory helps explain why we yawn in groups. Larger groups produce more carbon dioxide, which means our bodies would act to draw in more oxygen and get rid of the excess carbon dioxide” (http://science.howstuffworks.com/life/inside-the-mind/human-brain/question5721.htm).

I constantly yawn while exercising, and I was always taught that it’s not polite to yawn in class or when someone is speaking to me. So after learning this information, I will no longer take it personal that you yawn during the workouts. After all, your face and abdominal muscles are being used. I shouldn’t get upset anyways, since this is an involuntary action….but when you yawn, I yawn. It’s a chain reaction that’s contagious. Well, it’s 8PM, I’m yawning from being tired at this point, so that’s a wrap. Plus, I feel like my English teacher clients would note how many times I used the word “yawn” in this Blog and have re-read this multiple times to try to fix that. See you next workout, and maybe I’ll start tracking your yawn count in your files J
