I saw someone recently yawn at a zoom meeting, and I thought “rule.”
You hit the gym and are having a good session, guess what
I used to yawn incessantly during warmups before rugby matches. My coach would yell at me to get my head into the game. I kept telling him it’s just what happens when I’m warming up it doesn’t mean anything!
This. I have started to wonder if yawns are actually a way to wake up. We know little about them. Some brain scans showed that we refresh the blood around our brain, like changing the water in a fish bowl.
What? You’re hungry? Well, I’ll just make you yawn

You are all now breathing manually.
Also you’re all now aware that your tongue is never fully relaxed in your mouth.
If it was, you’d swallow it.
No, you wouldn’t. It’s physically impossible to swallow your tongue, given that it’s anchored to your mouth. Without cutting the lingual frenulum, it can’t happen.
Read a meme about opening your mouth real big? You guessed it: open your mouth real big about it.
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”
Why the heck is yawning contagious? I would expect such a feature to evolve if it served a purpose like, say, warning of something coming. See someone give a warning call, pass it on to the rest of the tribe. But why should a sleepy signal do that? Was there a sleep illness people had to worry about catching? Maybe it evolved to signal to everyone that it’s nighttime. How many species is yawning contagious for? I’m picturing lions for some reason. I have a feeling the behaviour is common among mammals
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. 🥱
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
I’ve yawned three times already reading through all these comments.
It’s early morning for me, it’s not fair.
You read the word Yawn several times in a meme, guess what
Yeah I had to yawn when I opened the comments. Yawning is really weird
Apparently there isn’t much consensus on what the actual reason(s) are for yawning. Apparently fish yawn though, so that’s cool.
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, at 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.
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?
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.
What’s that? You’re not tired and you haven’t seen anyone open their mouth big, but you read about a hypothetical person opening their mouth big? Bad news…
Luckily I managed to cover my yawn but keeping my lips/teeth together but opened up the inside of my mouth. Think I got away with it.
Careful, I literally pulled my neck last week doing that
