You read the word Yawn several times in a meme, guess what
Literally just yawned reading this meme, lol.
Yeah I had to yawn when I opened the comments. Yawning is really weird
Whatever you do, don’t you dare cover your mouth so we didn’t have to see your gaping maw
And the gas pump isn’t a parking spot.
And turn off your headlights if you’re parked.
And just stop being a clueless shithead all the time always.
Just saying
🥱
Dogs yawn as well, and it doesn’t only mean that they are tired, more like “I try my hardest to stay concentrated, but is really hard right now”
Read a meme about opening your mouth real big? You guessed it: open your mouth real big about it.
Co2
Isn’t the leading theory that yawning is more about cooling down the brain temp rather than a lack of oxygen or buildup of CO2?
Yeah, you are correct. There are several reasons. :)
Which does nothing to explain why it’s “contagious”.
I thought the idea was that back when we were in settlements, keeping watch out into the dark, the yawn would happen to a sentry if nothing was going on and would subconsciously signal to other humans, even the watch dogs that " nothing is going on, all is well" then spreading throughout the camp as sort of a psychic link, literally conveying information at the speed of light to anyone who can see you.
At least that’s what some article I read had to say about it
You saw an animal open their mouth big? Have fun.
Wtf
Just reading this made me yawn.
same! what is this WITCHERY!?1
oh gods dammit fuck aaaaall y’aaaaaall.
Yawn
I saw someone recently yawn at a zoom meeting, and I thought “rule.”
Got to make everyone tired so they don’t get you while you sleep.
Apparently there isn’t much consensus on what the actual reason(s) are for yawning. Apparently fish yawn though, so that’s cool.
Isn’t it a social signal, apebrain talking?
Are there any other involuntary social signals?
….erections?
I do prefer to let my erection do the talking.
^ -me to the police officer who pulled me over and asked if I knew how fast I was going.
Name checks out
It seems like it helps the brain switch modes (from low activity to high and from high activity to low). So yawning could help prepare the brain to pay attention to something important, as well as wind down for the evening. Hence both morning and evening yawns.
The contagious aspect could be as simple as “Oh, you’re changing modes? I should get ready to do the same.”
Solitary animals yawn too. Don’t if they can catch yawns, or how to test it.
Supplying oxygen to brain before task, reused in ape for social?
My entirely uneducated guess would be that its some, very basal, ancient, basically gasping compulsion, that… just never quite fully got patched out by the subsequent tens of millions of years of evolution.
Sort of the behavioral version of vestigal limb, way down at some fundamental nervous system level.
Have you seen a stork yawn? They push their spine out through their mouth
Best I can find, the 20 “most argued” reasons for yawning, as t least the 20 most in 1999
When a baby is crying on an airplane during takeoff or landing, I visibly and audibly yawn in front of them on purpose, so they catch the yawn and pop their ears.
How to tell if your baby is a sociopath with this one simple trick. For this trick you’ll need: a baby, a stranger, an airplane, and the power to suspend all critical thinking.
that is genius
You’re supposed to stay in your seat during take off and landing. Please, remain in your seat. Why do you keep getting out of your seat and silently scream at the babies?!
Who says you have to get out of your seat?
Snake yawns are the most cute of yawns and I will fight every one who says otherwise.
My idea is that yawing helps sync our internal clocks. So, we sleep at the same time, and wake up at the same time. That way, no one is left behind when the group starts moving to the next waterhole, or feeding ground.
A yawn is a signal to regain some alertness, so when you yawn in order to become more awake, it signals your fellow life forms they might want to be alert too. 🥱
