- MPSimmons - 12961 sekunder sedanThe contagious nature of yawning is so weird. It has to be evolutionarily advantageous because it's so wide spread, but it's also non-obvious.

Is that the paper in question?
- tempestn - 4224 sekunder sedanThere was an article posted recently about a new discovery around CSF flows during sleep too. It sounds like yawning causes similar flows, which could maybe explain why you yawn more when tired? It could be a compensation mechanism to provide a bit of the same effect you normally get when sleeping.

I’m looking forward to “yawn to unlock”.
Also, what’s the deal with that article image?
- calini - 3630 sekunder sedanYou know how yawning is also a social function, and seeing someone yawn makes you yawn? I just got forced into a good neurofluid flow reorganization session just by reading the title.

- eek2121 - 4817 sekunder sedanThis article made me yawn. :)
- ncr100 - 3280 sekunder sedan"To tire, perchance to yawn."
- zb3 - 2510 sekunder sedanI did not read the article. But my question is - does it mean yawning (like trying to yawn on purpose which in my case will make me "really" yawn soon) influences those fluids inside my brain?
Or - a change in those fluids makes me yawn?

Brilliant, I'll use that next time I yawn somewhere inappropriately.
