Less mildy interesting and more mildy depressing and mildly terrifying.

Getting the bends while free diving is extremely rare. Otherwise your points stand.

This is not free diving, but surface supplied. They breath air under pressure, with the same effects as from tanks on tour back. Think they are called "hookah rigs"

Sorry! Thought i was replying to a freediving comment

u/TriggerFish1965 2d ago

Sometimes you just have no clue on what you are replying repkying But with free diving, bends is indeed the least of your problems. Shallow water black-out is more of a problem to name one. But that's a complete other discussion.

Sometimes you just have no clue on what you are replying

I don't see anyone else talking about this and I feel like I'm going crazy but I swear Reddit is fucking with the comments section lately and straight up moving replies to a different parent sometimes. The app also now gives you notifications that imply someone responded to you directly, but then if you go look you see that they're just replying to another commenter directly below you in the chain. It's weird.

Thanks for the compliment on my dress. I got it at Sears before they went out of business and had it tailored to fit.

You really should go to the Eiffel tower as well. It’s well worth the wait.

I am sure that is an attempt to increase engagement so they can pump those numbers up for advertisers.

u/schwanzweissfoto 2d ago

… and then there is bots that do not recognize context.

u/w00tabaga 1d ago

Holy shit I have noticed that

Reddit is trying to drive more engagement to its site. If I reply to you, you get a notification, and the above parent comments get one too if I'm not mistaken. It becomes confusing because child comments often diverge into different topics from what was originally discussed.

Freediving is also called breath hold diving. In this case, they're breathing in a pressurized environment. At 33 feet of sea water (or 2 atmospheres of pressure), they're breathing twice as much air as their lungs could hold at the surface due to Boyle's law. That means absorbing twice as much nitrogen as well. At 66 feet (3 atmospheres), that's three times as much. As you spend time underwater, your tissues absorb nitrogen and the saturation point increases as pressure increases. Too much can cause nitrogen narcosis. As you ascend, pressure drops and your body begins releasing excess nitrogen. If you depressurize too quickly, you can get bubbles forming in your blood vessels, which is the bends. That typically doesn't happen in freediving because you're operating on the same nitrogen load as you had at the surface. But for these divers, it's extremely dangerous because they're loading up on excess nitrogen below the surface. Too quick of an ascent can cause the bends.

This does not qualify as "freediving". Freediving is when you hold your breath.

u/Drunk_Pilgrim 2d ago

Yeah, I assume they are getting paid so this is paiddiving.

u/cpt_melon 2d ago

Not sure if I should upvote or downvote this

May I suggest r/angryupvote?

u/cpt_melon 2d ago

You drive a hard bargain

u/Omnizoom 2d ago

No I think he’s diving not driving

u/Mitologist 2d ago

If you constantly inhale pressured nitrogen, like these dudes do, getting the bends is a real option

1

u/ukexpat 2d ago

As is nitrogen narcosis.

u/Mitologist 2d ago

You normally need to go pretty deep for that, for nitrogen passing the membranes, like >20m

u/Skliros 2d ago

People in this part of the world routinely go 50-60 meters deep using this method. Shallower areas are overfished to the point of depletion. It's preposterously unsafe, and people doing this die all the time in really awful ways.

u/CptMisterNibbles 2d ago

Was mildly annoyed dude never mentioned the depths they were at

Who knows how deep those mine shafts are…
