    You’re not tired, but you saw a post about yawning? Well, guess what.

      You are now yawning manually.

    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?!

      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.

        It’s more indicative of whether or not your baby is autistic.

    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?

        Solitary animals yawn too. Don’t if they can catch yawns, or how to test it.

        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.”

      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.

      Can confirm, I do struggle with empathy (more in the autism way than the socio/psychopath way though) and don’t really catch yawns from anyone. I will still pretend to yawn when someone else does though, because I know that not doing that will make them subconsciously wary of me

      source
      • anzo@programming.dev ⁨2⁩ ⁨weeks⁩ ago

        Not everyone will get wary if you don’t yawn. Same way as not everyone thinks the same way about yawns, or just over analyze what others do.

        But good for you to try mixin and minglin with the neurotypical crowd :)

        Just keep it relaxed

    • dependencyinjection@discuss.tchncs.de ⁨2⁩ ⁨weeks⁩ ago

      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?

      • Angelevo@feddit.nl ⁨2⁩ ⁨weeks⁩ ago

        Yeah, you are correct. There are several reasons. :)

      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.

      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 post literally made me yawn. Not because it’s bad either.

    source
  • DarrinBrunner@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

    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.

      Except nocturnal circadian cycles were evolutionary in nature. The pack wanted someone awake at all times to protect from predators.

    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. 🥱

      Also you’re all now aware that your tongue is never fully relaxed in your mouth.

      If it was, you’d swallow it.

      source
      • Diddlydee@feddit.uk ⁨2⁩ ⁨weeks⁩ ago

        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.

    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.

  • MrScottyTay@sh.itjust.works ⁨2⁩ ⁨weeks⁩ ago

    Yawning is more about getting more oxygen in your system. Which sometimes can be for to you being sleepy and not breathing as well, but always to do with tiredness.

    I think when you see someone else yawn, you do the same to make sure you’re just as on point as they are. Since more oxygen in your system means you’ll operate more efficiently.

    I think that’s correct, anyway? If someone knows better, please correct me

      Sounds like a plausible theory. I wonder how extensively it’s been studied. I’d like to know if it’s unique to humans. Figuring out which species do ot woukd give a clue to when it evolved

  • Petter1@discuss.tchncs.de ⁨2⁩ ⁨weeks⁩ ago

    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”

    I can yawn with my mouth closed.

      You can stifle a yawn with your mouth closed. It isn’t a proper yawn if your mouth isn’t open.

      source
  • FreshParsnip@lemmy.ca ⁨2⁩ ⁨weeks⁩ ago

    Why the heck is yawning contagious? I woukd 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
