Swallowing is a mechanical action done with your muscles; that's how astronauts can eat and how you can eat or drink upside down if you were really wanting to.

Saw someone drinking a whole beer from a funnel while being being held upside down. People do this and I basically die when drinking a sip of water while lying in bed.

[-] FooBarrington@lemmy.world 35 points 2 weeks ago

Maybe the issue is that you're too horizontal? Try doing a handstand first.

[-] Kolanaki@pawb.social 12 points 2 weeks ago

And don't forget the funnel.

That’s a lot of fucking honey!

No, honey definitely exists

[-] ignotum@lemmy.world 15 points 2 weeks ago

Honey is a lie told to us by the bees in order to trick us into building beehives for them

I think there was a science experiments book for kids that dared me to drink water from a glass upside down through a straw while hanging from monkey bars or something. It was meant to show how our body deliberately moves food towards the stomach instead of solely relying on gravity, but instead it showed that I my legs were too weak.

A shame these experiments are deemed to dangerous nowadays and people have to show their ignorance online, simply because the new metal straws have pierced the brains of anyone who did them.

[-] notabot@piefed.social 14 points 2 weeks ago

because the new metal straws have pierced the brains of anyone who did them.

I am confused by this, straws go in the mouth, if people are sticking them in their brains, they're doing it wrong, or are you saying there is a crack team of assasins out there who've vowed to keep this knowledge secret in a particularly gruesome manner?

[-] Tudsamfa@lemmy.world 13 points 2 weeks ago

I implied that I fell from the monkey bars, and since I was drinking through a straw, I fell head first onto my water glass with the straw in my mouth that was below me. A common misconception of metal straws is that they are dangerous and can pierce through the mouth into the brain.

I guess I could specify where the glass is in the experiment.

good question actually, the esophagus can squeeze things towards the stomach without gravity's help.

[-] mic_check_one_two@lemmy.dbzer0.com 20 points 2 weeks ago* (last edited 2 weeks ago)

It’s even cooler than that: The esophagus can squeeze things towards the stomach against gravity. You can drink water while hanging upside down. You’ll also get a nose full of water because your sinuses would be below your mouth… But once it’s in your throat and you’re swallowing, it’ll make it to your stomach just fine.

If you wanted to avoid the sinus problem, I guess you could just lay on your back on a steep incline. Not fully upside down, so your sinus cavity is still above your mouth. That way the water would hit the back of your throat where you could swallow it, instead of just draining straight into your sinuses.

[-] xzinik@feddit.cl 12 points 2 weeks ago

what!? i can clearly remember being like 10 hanging upside down from my knees on a jungle gym and drinking water from a bottle and having no problem at all and proving my mom that i wouldnt choke doing that

Some poor soul has never watched Bill Nye the Science Guy... what has the world come too... D:

[-] trxxruraxvr@lemmy.world 35 points 2 weeks ago

Most of the non-English speaking world hasn't seen him as kids. I don't remember where I learned about peristalsis, but I grew up just fine.

[-] megopie@beehaw.org 32 points 2 weeks ago

This was legitimately a significant concern that early space programs had. Like, how well would people be able to swallow in free fall, would certain kinds of food cause problems? The food experiments during the Gemini program are pretty interesting

[-] mlg@lemmy.world 29 points 2 weeks ago

I'm too lazy to find it now, but one of the tests they tried long before NASA started sending people into space was eating a banana upside down where they figured out the digestive tract can function against gravity.

There was also an encyclopedia brown story about this in which I remember Geese and Ducks rely on gravity to swallow, therefore they wouldn't be able to eat in space.

I've just realised that because of my esophageal dysmotility I wouldn't be able to eat in space.

Is this a writing prompt about being left behind on a dying earth because you'd starve on your voyage to Mars?

Does this happen to your blood too?

[-] ajmaxwell@lemmy.world 26 points 2 weeks ago

There's a slight increase in the blood pressure in your upper body, and a small possibility of thrombosis, blood clots forming in your veins. But after 50+ years of space flight no one has had complications.

Veins are small so capillary action keeps things in order.

With no gravity though you'll have higher blood pressure to your head (and less to the legs)- it kinda makes astronauts faces a bit puffy. iirc this can slightly negatively affect vision long term.

Most of your body processes are in a small enough space that capillary action overtakes gravity.

If you put it on a sandwich, yes.

[-] hperrin@lemmy.ca 15 points 2 weeks ago

I don’t know about you guys, but I just open my throat straight down to my stomach and pour the food in.

[-] CultLeader4Hire@lemmy.world 10 points 2 weeks ago

Baby bird style

[-] KiwiTB@lemmy.world 14 points 2 weeks ago

Given how filthy the ISS is, I don't know if I'd want to eat anything not nuked into oblivion.

[-] trxxruraxvr@lemmy.world 8 points 2 weeks ago

Why would it be filthy? It's not like they get a lot of dirt out there

[-] yakko@feddit.uk 17 points 2 weeks ago

Dust comes from human skin flakes.

[-] CosmicTurtle0@lemmy.dbzer0.com 10 points 2 weeks ago

There a giant vacuum though.

[-] Valmond@lemmy.dbzer0.com 27 points 2 weeks ago

Just open two opposite windows.

Well that didn't work (windows outlook debacle).

Can you swallow things when you're laying flat? I imagine swallowing food in space would be no more difficult.

[-] exasperation@lemmy.dbzer0.com 33 points 2 weeks ago

You can swallow things while dangling upside down. The esophagus is strong enough to work against gravity.

But liquids are a little bit more difficult, because they tend to flow in unexpected places in the mouth/sinuses/nose before trying to swallow.

[-] CultLeader4Hire@lemmy.world 10 points 2 weeks ago

Once I had to drink barium while being tilted upside down on a big table while they watched it with X-rays… apparently that’s a medical test lol I didn’t find it anymore difficult than drinking normally personally but it has to do with the strength of your swallow most of all, which is what they were testing at the time.

[-] spicehoarder@lemmy.zip 13 points 2 weeks ago

We get it, you're good at swallowing

What would a bee do in zero gravity?

[-] JackbyDev@programming.dev 9 points 2 weeks ago

Oh that's interesting, I wonder if it's easier to get heartburn in space? It's common to need to sit upright to keep the acid down.
