I’ve come to notice that every once in awhile, towards the end of a training session I’ll start to yawn. I can be breathing heavy and training hard but still manage to yawn.
This always happens towards the end of a work out when I’m more fatigued. It’s got to be a common thing because I know a few other guys that also yawn late workout.
Of course it’s due to a lack of oxygen. I’m just curious to see if anyone has ever actually researched and attained the facts.
I read somewhere you also yawn to cool down your head, which would make sense if you’re doing intense training. Not sure quite how reliable that is though.
I knew seeing someone else yawn makes one yawn, but I didn’t know just reading about it would make someone yawn… yet, I yawn. And it won’t stop anymore.
On the topic… nope, never yawned during training. I train at home tho.
Maybe this lack of oxygen thing really is the reason… in the gym there are alot of other people, using up the air. This isn’t the case if you train at home.
