Interestingly repetitive yawning is often experienced by migraine sufferers just before the onset of a new migraine. It must be linked to blood flow and changes in vasculature somehow. Very interesting 👏

I’m Audhd and I yawn constantly when I’m overstimulated from noise and things going on around me but I’m not sleepy. This makes sense, my brain is working harder from processing everything so needs to keep flushing the metabolic waste from it and keep supplying fresh blood for oxygen nutrients etc to keep up with the demand
