scorpion wrote:Sorry the post does not excite but you regarding your yawning... Years ago people used to believe that yawning was a sign that there was not enough oxygen getting to one's brain. When tested scientifcally that belief proved false. Just thought I would give you a lttle history on the yawn.
These data indicate that yawning is, indeed, a biological thermoregulatory behavior, triggered by increased ambient temperatures.
But why do we care about yawning? There is a growing body of medical and physiological research that links increased ambient temperatures with the unpleasant symptoms of certain medical conditions. Further, it has also been noted that yawning often precedes an epileptic seizure or a migraine headache among those who suffer from them, and increased yawning is also associated with multiple sclerosis.
