A Couple of Things I Learned While yawning!

 

#141 December 12:  Why do we yawn?  According to a website I consulted, it is to both cool the brain and oxygenate it to make it more alert.  A yawn, especially in cooler temperatures brings in cooler air and adds oxygen to your brain, literally waking it up!  It occurs whenever your brain needs oxygen, or is hot and needs extra cooling and focus. But why are yawns “catching”?  12/17

 

#142  December 13:  According to Real Simple and the National Institute of Health, yawns are contagious and are caused  by empathy. It is called social mirroring and can occur even between species, such as seeing a zoo animal or cat yawn. 12/17/2023
