I heard about this recently from a different article, but from my understanding, when we yawn, cerebrospinal fluid moves away from our brains. Cerebrospinal fluid “keeps the central nervous system running smoothly, delivering nutrients and removing waste.”
So, as a laymen, I think our brains are flushing the gunk out when we yawn. Having to yawn a second time, to me, would indicate that we didn’t get all the gunk out the first time.
It's called air hunger and is a mild form of shortness of breath and I get it constantly. (Edit to add: I know EXACTLY what you mean by the jaw thing and that arbitrary bodily sensation of "u did it wrong tho do it again :( but right this time..." and then it keeps going and going and going until you finally manage to breathe in right somehow.)
Not a doctor but I am an RN (but still not your RN).
hm check iron level is something I read with other symptoms I show as well....maybe it is time to do just that.
It can be air hunger, or may be nothing more than a yawn for no apparent reason.
We really don't understand yawning all that well.
If it happens frequently for someone, like throughout every day, then maybe it's exposing a problem.
I mean it could be something else, but that thing they're describing where they have to work their jaw and do it again and again until some arbitrary sense in their body decides they finally did it right... It's just too familiar. Like they're describing EXACTLY the same sensation. That is EXACTLY how I would describe the feeling. And that's what fixed it for me.
Thank you. I feel like there is a certain point at which go 'pop' when they are fully filled and it just doesn't feel like a deep breath or full yawn when I didn't feel that
I know this feeling. I'm not a doctor and I can't offer a thorough explanation. I am prompted to share my experience though in the hope that you find it helpful.
For a long time I was focused on forcing the yawn or otherwise putting effort into it as you described. What I realized was that the missing ingredient was the depth of my breath. My body is trying to relax, initiated a semi-autonomous routine to do that, and I'm interrupting it.
When I'm too tense I have trouble yawning. If that's happening the only sure way I've found to satisfy the yawn is to drop my shoulders, breathe from my stomach first, and let the yawn take over. Sometimes the jaw still ends up pushing open quite wide. Sometimes not. The key is that I'm not trying to control it either way.
Now it feels as odd to force my own yawn as it does to overthink my own breathing. The only viable solution seems to be giving up on control over it and letting my body go on autopilot instead.
I hate yawning. It often causes a muscle to pull in my jaw area and it takes a few minutes to clear out. Sometimes a day.
I prevent myself from opening my mouth too large.
Yawning is so fascinating. It's often contagious, even between humans and other animals, it's an involuntarily reaction and can happen repeatedly in quick succession like sneezing, and reading and/or thinking about it can trigger it (as has happened to me multiple times while writing this).
I can't directly answer your question, but what I can say is that it must be important as far as evolution is concerned. In addition to all of the above, it negatively impacts multiple important senses simultaneously, and to your point, we can somehow feel whether or not the yawn was sufficiently satisfying.
Agree -it's super interesting! I took a med that made me yawn a lot. Was weird, but it also helped reduce murder urges, so that was worth it. Studies show that some people with autism don't catch yawns.
Even just reading the word 'yawn' makes me feel the need to yawn. I gotta imagine that's because my brain is visualizing someone yawning when I read the word.
Yawning is so fascinating
It really is. Friend of mine had a cat that would meow in a special way every time a human yawned. We tried endlessly to fool it by fake yawning, but it could tell every time and only meowed during real yawns.
I get this sometimes when I have anxiety. Almost feels like I can't breathe enough, and I have to keep yawning.
Yawning in general is still quite a debated topic in science. Its purpose is not fully known.
We don't even know why we yawn in the first place.
I immediately had to yawn when I finished reading this haha.
Maybe the same as a "ruined orgasm"?
A yawn is the brains wish to not have to even and sometimes you don’t get quite enough on the first dip so you have to not have to even even more
Sometimes yawning is triggered by a perceived need to get more air (CO2 build-up in the body). The lungs might sense that CO2 went down after yawning, but then the blood deposits more as the lungs were no longer saturated with CO2, and after that you need to yawn again.
Or it's randomly triggered by some other reaction 🤷
People doing cardio and people exposed to elevated co2 don't yawn, yet dogs yawn when they see people yawning so its probably not that simple.
I always thought of it like, we're all comfy and safe social signal. It makes you feel a bit sleepy as well, and it's contagious because it makes other people want to return the signal. That's just my theory though. A personal theory!
I mean, when I see videos of animals yawning, like lions, I get the urge myself to yawn. So definitely a complex topic.
The co2 bit it's part of it, but coming down the brain is another aspect of what makes people yawn.
