What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

Seems like if you read between the lines, there's a certain commonality in increased respiration/alertness, stress response and showing of teeth that solves a common need across species. When a subject recognizes a lack of alertness, a present threat or the need for aggressive action in the near future, a yawn can help prepare for that while also giving pause to those who might be threats and/or potentially paralyzing prey. The failure in consensus here appears, to me, an inability to describe those seemingly disparate needs as related to the physiology that drives them. Not a lack of understanding, so much as a deficiency in perlocution.

Ay yo so I was bout to tell you how that's all wrong, but then you go throwin out words like "perlocution" and now I realize you probly know what the fuck is up, so I'm just gonna trust.

I've read that people with autism are less likely to catch a yawn. Not sure if that's true.

I've taken meds that caused uncontrollable yawning. That's super annoying!

[–] Cornfed@lemmy.world 5 points 1 year ago

It was the picture for me

[–] Jebus@reddthat.com 8 points 1 year ago* (last edited 1 year ago) (1 children)

I watched a video a couple years ago where they did an experiment with chimps. I thought they concluded that the "cantagious" yawning has to deal with the animals empathy and wanting to be like others, it was a social thing in pretty sure. I have no idea where to even find this video though so take that with a grain of salt

[–] frozen@lemmy.frozeninferno.xyz 7 points 1 year ago (1 children)

Mythbusters rated contagious yawns as plausible, I believe, because they observed multiple instances of yawns spreading throughout a building where the participants couldn't see each other.

[–] Jebus@reddthat.com 2 points 1 year ago

Its all pretty interesting to think about honestly! Hopefully we get an actual answer instead of just speculation!

[–] Num10ck@lemmy.world 6 points 1 year ago (2 children)

i thought it was to clear out carbon dioxide build up deep in your lungs, and instinctually its an indicator of rest?

[–] NovaPrime@lemmy.ml 2 points 1 year ago (1 children)

As someone with asthma and lowered ability to cycle out CO2, yawning has always helped me restore the "full" feeling and your comment just made everything snap into place.

The primary driver of suffocation panic, pain, and feeling of air starvation isn't the lack of oxygen but CO2 buildup. It makes sense that yawning on command could then help alleviate the symptoms of CO2 buildup in asthma sufferers.

[–] Nomad@infosec.pub 2 points 1 year ago

Might be a group protection mechanism to indicate low oxigen in crammed spaces qith many individuals. In addition to that could be a geoup trigger for rest.

[–] Digestive_Biscuit@feddit.uk 1 points 1 year ago

I always thought it was due to clearing the lungs out or to regulate them but then I saw a turtle yawn under water. I then thought it's ancestors wouldn't have been swimmers so maybe it's instinctive still, but then it would need a mechanism to prevent water inhalation. So why retain the yawn.

Perhaps as you say it's more about visual communication to others around you.

It's from when caveman wanted to leave their friends cave and go home, but can't get an ugg in and they don't want to be rude.
