Question: Yawning when Exercising


 nanibuggie - Thu May 22, 2003 12:09 pm

Does anyone know what causes yawning while exercising?

Everytime I run or even do jumping-jacks, I yawn continuously.

Please tell me how to fix this problem.

Thanks. :D

thank you for those excellent websites, however, none of them seemed to give me an answer :( i guess i'm not the only one, however, with this problem#since both those sites did indicate that excessive yawning could happen during exercise##but no reason why.

thanks again! :D

I too, yawn during exercise although I don't notice anyone else doing it. I'd like to know why I do this?

User avatar siebrass, nanibuggie,
Yawning is a normal stretching mechanism. Its similar to stretching other muscles in the body. Normally we stretch when we feel we need to. Our muscles contract and squeeze the blood in the veins which is poor in oxygen and have it replaced by new oxygenated blood giving us a feeling of renewal. That isnt the only reason why we yawn obviously. Its also a contagious phenomenon, which hints at a strong psychological effect. Many theories have been proposed it remains a mystery why we should yawn to start with.

Now about exercising and yawning excessively. You are not the only ones. Its been documented in some rare individuals. Again no scientific explanation has been found. The important thing is to rule out obvious causes: sleep deprivation, general fatigue (prior to exercising), some antidepressants (SSRI-class antidepressants like Prozac) can all cause excessive yawning.

If what you have is non-stop yawning and not just excessive yawning during exercise, then you should consult a doctor. This could be a sign of an underlying vasovagal (heart rate and blood pressure) problem.
