for background, I shaved my forearms for practicing methods of shaving my legs. low-key a mistake, don't think id recommend shaving arms lol

I picked up a pizza after getting a shower and to dry out my hair faster I didn't turn on the AC, was in a hot car in Florida for like 5m while it cooked and this is what happened. Pretty cool!

Edit: also it's interesting to visualize how much water is lost when you sweat

The other day I had a weird experience with pores and sweating.

I was given a family-sized bag of chips that were "too spicy" for my parents. They were spicy, sure, but not painfully spicy.

However, my body's reaction was not the usual sweating... It was to excessively sweat from a square inch spot just above my temple.

I could literally FEEL the sweat coming out of the pores. I went to the mirror and watched it pour out like a damn faucet. It was fascinating but very uncomfortable, both physically and psychologically

Super weird.

Jokes aside, it was nearly a steady stream off my head. I had to make a bath towel turban

[–] dontbelievethis@sh.itjust.works 13 points 6 days ago

Maybe you are leaking brain fluid. Do you hear the ocean?

[–] victorz@lemmy.world 45 points 6 days ago (5 children)

Wow, that is super weird actually.

Reminds me of an incident I had a few months ago. I arrived at work, by bike. I hadn't taken the bike for a good while, and I biked harder than I should have. Anyway, I sat down by my desk, and I started salivating.

It wasn't too much at first, I could keep up by swallowing. I immediately attributed it to the biking and wrote it off, and thought it would pass soon.

But it didn't. It kept getting worse. More saliva, and faster. I was swallowing mouthfuls at this point, and it was uncomfortable. Like I was being forced to drink lots of water, or being waterboarded.

At last I reached my breaking point and I swiftly walked to the bathroom, locked the door, and just stood with my mouth open and tongue hanging, over the sink, and it was just running, like a faucet opened just enough to be running yet not dripping. This is the part that was similar to your experience—I could feel my saliva... glands? excreting the saliva.

Anyway, this went on for about a minute or two, then it stopped, and I went on with my day.

Have never had something like that happen before, and not since.

[–] glimse@lemmy.world 25 points 6 days ago (1 children)

That's even more bizarre than my story lol

Usually excessive salivation is a sign that I'm about to vomit so I think I would have wound up in the stall as a precaution

I have something similar happen to me when I eat kiwis. The top of my head just starts sweating.

[–] glimse@lemmy.world 9 points 5 days ago (1 children)

I know a lot of people are mildly allergic to kiwis so I looked up the symptoms and stumbled on something unexpected... Frey's Syndrome:

Sweating (face, neck, temples) triggered by food. Usually a result of gland surgery, it can also be caused by ingrown hairs near the auricotemporal nerve.

I've suffered from ingrown hairs my whole life (yes I bathe regularly) and definitely have had some near my ears. It's almost too coincidental...

It does that when you don't shave too.

[–] Gladaed@feddit.org 14 points 5 days ago (1 children)

No, it does not for the hairs distribute it. This beading is unusual on arms.

[–] _haha_oh_wow_@sh.itjust.works 8 points 5 days ago (2 children)

Guess it varies by individual, I am hairy but sweat still beads up if it's hot enough or I work out hard enough.

This also is a cautionary tale: hairs make sweating more efficient as the water distributes better.

[–] GreenKnight23@lemmy.world 23 points 5 days ago (2 children)

preposterous! hairy girls are way hotter.

[–] Gladaed@feddit.org 9 points 5 days ago

And they can be! Safely! For the power of hairs!

I find your water discipline lacking. May Shai Hulud forgive you.

[–] Diddlydee@feddit.uk 51 points 6 days ago (5 children)

Where did you think sweat came from?

[–] shnizmuffin@lemmy.inbutts.lol 20 points 6 days ago

The eyeballs. I only sweat when I'm sad.

Sweat is stored in the balls.

[–] BleatingZombie@lemmy.world 6 points 5 days ago

Mine seems to be stored ON my balls

[–] SolidShake@lemmy.world 34 points 6 days ago (1 children)

Wait... How old are you? And where did you go to school? (Country)

Turning the ac on with heat will help pull moisture out of air! Ac is a natural dehumidifer.

[–] _haha_oh_wow_@sh.itjust.works 32 points 6 days ago
[–] fartographer@lemmy.world 19 points 6 days ago (14 children)

AC... Natural...

Dehum-idifier...

Need I say more?

[–] MurrayL@lemmy.world 9 points 5 days ago* (last edited 5 days ago) (3 children)

Just dropping in to say what follows in this thread is the most pointless, overblown argument I’ve seen in a very long time.

Full-on, unironically, arguing over dictionary definitions with each other and trading insults.

This is what the internet does to some people. Look on and despair.

Mid-key no. Sweat always comes of of pores.

[–] spankmonkey@lemmy.world 19 points 6 days ago (1 children)

It also beads up when you don't shave. Had that yesterday with my hairy gorilla arms when sitting still and trying to cool off.

[–] colourlessidea@sopuli.xyz 12 points 6 days ago

+1, not sure if shaving has anything to do with it. You can see this beading up quite easily in a sauna for example

[–] victorz@lemmy.world 15 points 6 days ago (1 children)

was in a hot car in Florida for like 5m

Dang, must have been really hot for you to start sweating like this after just 5 meters. 🙃

[–] Onomatopoeia@lemmy.cafe 12 points 6 days ago (3 children)

It's Florida - OP was sweating like this in the first meter
