When I worked in critical care, I learned that mechanical ventilators are set to give patients a "sigh" breath every so often during the cycle. Apparently this deep breath is needed to maintain the proper pathophysiology of the lung tissue. People (not on ventilators, obviously) will yawn periodically, which produces the same effect. I don't know if researchers understand why we yawn more when tired, though.

I didn't yawn at all. Our body temps vary slightly (excepting fever cases).

Sarasu Ajayakumar, my body temperature vacillates. There may be very little difference but I’ve had lows of 96.0F and highs of 98.0F frequently

As far as I know our body temperature is constant. It goes up during fever.

A great yawn inducer, shiver inducer if you read it in the freezer and tear inducer if you read it to the end

Very interesting! I didn’t know all of them, but it is nice to learn new things. Usually we take everything for granted, without asking too many questions.
