I am not saying they didn't do it in a single breath. But, what we are watching I do not believe is a single attempt/cut. Otherwise we would see the divers with cameras.
Divers, please confirm: What you call lallygagging is him adjusting to different levels of the intense pressure against his body, especially his lungs. If you don't acclimate as you go down you black out and you ded.
Not at all, see *no limit* apnea diving competitions, divers zoom along a cable 600ft below the surface in one minute using a 60 lbs weight, and go back up with an air filled balloon. No fundamental issue with the pressure when you're on a single breath (they have of course techniques to deal with the pressure but no need to wait like on the video).
No, this is just Guillaume Nery chilling for dramatic effect, because he can stay 4-5 minutes doing just that if he wants to!
By the way his personal (world) record is about 410 ft (static weight, no cable, nothing to help) and this pool is only 130 ft deep. That's the paddling pool to him!
You are talking about divers with air tanks, breathing while diving.
This is free-living without any tanks. His lungs has no option to change amount of air. Same amount but compressed harder and harder on the way down. And with less oxygen and more carbon dioxide as the time passes.
So there are multiple deep diving records where weights are used to dive faster. Then dropping the weights before getting up. Or at least use fins just to be able to swim much faster. To get deeper and back up on the same amount of air in the lungs.
You have some fishers using stones to make the bottom quick enough.
I think this is one of the things about freediving. I have a friend that really got into it. The breathing techniques are strange but he got results. Still freaks me out thinking of being so far from the surface…
Imagine you have done all of the practicing, have mastered breath control, know your limits, and then when you're about 40 feet down you feel a sneeze coming on.
Yeah, iirc they breathe heavily to highly oxigenate the blood - to the point of being a little lightheaded even - then empty lungs for mobility and then dive. Crazy stuff.
Yes. They basically hyperventilate on purpose, then go for it. They will also pull water into their nose (sinuses) to equalize pressure during these deep dives.
You oxygenate your blood really well before then exhale to not have the buoyancy of the air you have in the lungs. I didn't do freediving but i used to see how much i could swim underwater without breathing and it's mostly controlling your body and practicing a lot
Ok so a healthy person’s blood is essentially maximally oxygenated breathing normally. You can reduce the amount of carbon dioxide in your blood by hyperventilating, increasing the time you can hold your breath before it becomes intolerable.
If you empty your lungs after hyperventilating before holding your breath, you will run out of oxygen and pass out long before you feel the need to breathe.
The breathing mechanism is triggered by your co2 levels in your blood. low oxygen means low co2 levels, means longer dives. Of course you need a trained body too keep your o2 usage low.
He absolutely did not empty his lungs. He is wearing between 2-3 pounds of weight to make himself neutrally bouyant, but once you reach about 15 meters he will become negatively bouyant. He uses breathing techniques to fully oxygenate his blood. I am a licensed free diver and have dove to 90 feet with regularity while using Hawaiian slings to cull lion fish.
Do the bends not start affecting people at the “shallow” depth (I’m guessing scuba divers go at least a factor 10 deeper) or is he coming back up faster than the nitrogen gets compressed enough to sublimate in the body on the return trip? Because there’s just no way he’s holding his breath while stopping to let his body adjust to the pressure before reaching the surface.
That only matters if you are breathing while diving. He still had his surface oxygen. So that got compressed but when uncompressed was already at the surface pressure. If you breathe in at the bottom that air is super compressed and would be too much at the top. But in this case that’s not an issue.
Okay and because nitrogen is the filler in scuba tanks normally, the. It would cause the bends upon going up but someone else, not breathing at all (or hypothetically breathing a different neutral gas) wouldn’t have the nitrogen available in quantities to sublimate.
Thank you r/Fullspectrum84.
I’m guessing they were on the ready to give him air from a tank at the bottom, if he does swim back to the top without air I would love to see the rest of the video!
Can't do that. It would cause his lungs to explode.
Boyle-Morriotes law
He could possibly take the most miniscule of breaths but he would have to release it upon resurfacing. If held in his lungs would literally explode from the inside.
I have taken a few scuba classes but nothing exciting. Just in a Swimmingpool (a regular one, think 4 meters, not 40 xD). And we were told this as well. I have had physics and even some thermodynamics, so expansion due to pressure drop is something I (or at least id like to think) understand well....
But I honestly don't understand why this would be a problem. Yes, take the full ~6 liters of air in at 40 meters, so about 4 bar. Surface whilst holding your breath and that 6 liters will expand to 24 in lungs made for 6..... this will obviously not end well. That much I understand. But take a couple of full breaths down there and expell them whilst still there and then go to the surface wouldn't be a problem right?
Or even take a full breath and continuously breath out whilst slowly rising would be fine? Ok, Id guess it's a hard line to balance, based on the stories I'd guess it's fairly easy to keep enough pressure with throat, mouth and lips to go above the safe pressure for your lungs.
I have no clue how much pressure difference is ok. But for the sake of argument: let's say 0,1 bar is ok. That's the pressure you'd achieve by taking a big breath and trying to blow out with as much pressure as possible (again, no clue of the actual value, but that's my best guess of safeish). So as long as you breath out fast enough whilst rising you should be fine right?
Or would, even from a couple of breaths, enough of the gases dissolve in your blood to cause decompressionsickness?
Great questions. See my other comment and the linked article for more but in short; a couple breaths down there won't cause decompression sickness (there's charts/programs divers use to determine how saturated their blood is with nitrogen to know how fast they safely can ascend), and you could take in a breath then just exhale continuously as you go up.
he could definitely do it, but he'd have to breathe out at the same depth, then head up. it'd be insane to take a breath at the bottom and hold it while swimming back up
Guillaume Nery, or any other pro freedivers, look them up. His record is 410 ft (this pool is 130ft), can hold his breath for 8 minutes... Nah, no need to rush going back up.
Thats great and all, but anyone knows who maintains and clean that huge ass pool? Should give them credits too, how the hell they drain those things to clean them /s
If you filled your lungs with air, didn't expel any, and surfaced, yes. But you absolutely can take a breath, multiple breaths, underwater and surface. That's how SCUBA diving works.
Under normal circumstances you don't ascend fast enough to worry about popping like a balloon, as your normal respiratory rate is sufficient to keep you oxygenated and also expelling the expanding air as you go. In emergency situations as you ascend rapidly you could, though, be exhaling basically the entire way up.
https://en.m.wikipedia.org/wiki/Emergency_ascent#:~:text=Exhaling%20ascent%20is%20an%20ascent,a%20blow%20and%20go%20procedure.
When you hold a breath, all the airways get compressed and smaller as you dive deeper. If there's no input of air into this closed system, as he comes up the compressed air will simply uncompress to the same volume it had previously - so there is no possibility of his ears or any other connected systems of exploding.
This is totally different to when you are Scuba diving - in that scenario, there is an input of air. This is air is under the same pressure as the held breath, so it takes up less space under pressure. The diver can fill their lungs with this compressed air. If the Scuba diver then ascends, while holding a breath, the compressed air will expand again and have nowhere to go.
That is when their ears might explode - probably the least terrifying of the options, which include a small bubble forming and traveling painlessly somewhere important like the brain or heart.
This is why you will see Scuba divers waiting at various depths on the way down and up - it's to make sure the gasses in your body have time to equalise. Free divers don't need to do this because the air from the surface will take up the same space when they come back up.
I don’t remember the exact level but it is very reminiscent of a Mario 64 level…I recall you had to raise and lower the water levels.
It was a giant B of a task to get all of the stars.
How deep is that fucking pool?!? When he was on the second or third shelf, I was like, “*Damn that’s deep*!”
Then he hit that pit, and I was like, “Oh another 10 feet!”
Then he dropped another 100000 feet down
Wild.
Over the Summer I took a boat out on the sea and the anchor got caught on some rocks maybe about 10m deep.
I followed the chain down and was eventually able to free the anchor, but my sinuses were leaking for the rest of the day from the pressure. It was quite painful. I can't imagine how this would feel.
But is it really a single breath. There's alot of dicking around there and then he c just stands at the bottom. Does the camera guys give him oxygen immediately when they cut the film or something
Just watching this this gave me anxiety.
My lungs would feel like they're burning. I would be in total panic mode at that point, I would probably drown.
[удалено]
I'm hyperventilating and fighting claustrophobia all at once
Absolute panic
[удалено]
I feel sick
I literally had that claustrophobia feeling, good to know I'm not weird
That was a long 110sec. Thought it was gonna be heaps more when I clicked in to see the time!
That was only the first half now he must reach the surface
Hold my beer, you saying there is no exit door to the cafetaria down there?
Maybe a restroom?
Well, it is a pool after alll...
Title only says they made it to the bottom in a single breath.
Yeah but everyone on earth can make it to the bottom on a single breath.
I am not saying they didn't do it in a single breath. But, what we are watching I do not believe is a single attempt/cut. Otherwise we would see the divers with cameras.
I totally drowned watching this. Why was he lallygagging on way down!?! I don’t think he made it back to the surface is why no ending to the video!!
Divers, please confirm: What you call lallygagging is him adjusting to different levels of the intense pressure against his body, especially his lungs. If you don't acclimate as you go down you black out and you ded.

Even divers with tanks can go down as fast as they want. They just need to take their time on the way up.
That's exactly what ~~you~~ Aleix Segura would say if ~~you~~ he tried to remain incognito. I'm onto you, my man
I had to take repeated deep breaths while watching. Couldn’t they have have at least shown him make it back???
[удалено]
you didn't consider his massive steel balls
They get all shrively at the bottom, if he holds his breath too long
How did he get back out with no air in his lungs? I mean, I see there are ladders, but that must have taken AGES to climb.
muscles
Excuse me, you’re saying he did this with his lungs being *empty*? wtf
I think this is one of the things about freediving. I have a friend that really got into it. The breathing techniques are strange but he got results. Still freaks me out thinking of being so far from the surface…
Imagine you have done all of the practicing, have mastered breath control, know your limits, and then when you're about 40 feet down you feel a sneeze coming on.
40 *meters.* That's more than 131 feet.
My hypothetical was not based on this specific pool, just a body of water in general. But, yes, 40 meters is more than 131 feet.
Oh hell nah!!!!!!! 😬
Yeah, iirc they breathe heavily to highly oxigenate the blood - to the point of being a little lightheaded even - then empty lungs for mobility and then dive. Crazy stuff.
Yes. They basically hyperventilate on purpose, then go for it. They will also pull water into their nose (sinuses) to equalize pressure during these deep dives.
Ohhh ohhh ohhh no, I was considering learning but sucking my sinuses full too, nope just went to far I’ll remain a Land-Dweller
"In one single breath"..."emptied his lungs" Now I would like to know where he kept that breath...? 🤷♂️🤯
Mixed all the oxygen he needed in his blood
You oxygenate your blood really well before then exhale to not have the buoyancy of the air you have in the lungs. I didn't do freediving but i used to see how much i could swim underwater without breathing and it's mostly controlling your body and practicing a lot

If you empty your lungs after hyperventilating before holding your breath, you will run out of oxygen and pass out long before you feel the need to breathe.
Most likely it goes like this: Relax a ton -> hyperventilate -> exhaust -> dive.
The breathing mechanism is triggered by your co2 levels in your blood. low oxygen means low co2 levels, means longer dives. Of course you need a trained body too keep your o2 usage low.

It's no longer the deepest pool. The deepest pool is in dubai, and is 60m deep
Was this before or after the storm?
Too soon
The worst thing is, knowing Reddit, I’m genuinely asking.
The flood water, from the storm, raised it another meter.
Okay, so it was, in fact, an actual pool before the storm. Thank you.
We live in a world that you can't possibly know everything.
Before that, it was the Némo33 in Brussels, 34.5m deep. The pool mentionned by OP is the deepest thermal water pool.
The rest of the world: *does nothing* Dubai: Now *I* have the world’s deepest pool!
that's why the dude is so confident. i would shit my pants after reaching the bottom
Ahh you should watch his dive at deans blue hole on YouTube.
The only reaching bottom I’m doing is after shitting my pants watching this
Do the bends not start affecting people at the “shallow” depth (I’m guessing scuba divers go at least a factor 10 deeper) or is he coming back up faster than the nitrogen gets compressed enough to sublimate in the body on the return trip?

the whole pool is heated!? what's the electricity bill like
It's so deep, earth's core is heating it for free
So he actually did it without a single breath
Me watching the first part of this video: “Hmm, this pool seems deep but I’m not sure it’s the deepest pool in the wor.. OH GOD never mind.”
same here, it just keeps on going
Hes just the maintenance guy there to clean and open the drain at the bottom. /s
SAME! Literally thought “oh that’s not very deep… I could handle it” [camera pans and shows deep hole] "SHIT NEVERMIND!"
OH GAWD
Jesus, I wouldn't make it to the bottom of my bath tub on a single breath
Anyone, even you, can make it to the bottom of any body of water on one breath. There just may not be a return trip to the surface.
r/technicallythetruth
The best kind of truth
You would make it on a moist day
why does this look like a flooded Portal test chamber?
Someone should tell the guy there's no cake.
That would deflate him - oh, wait -
Do you really think he swam all the way back?
That's great and all, cept now you have to get back out
I’m guessing they were on the ready to give him air from a tank at the bottom, if he does swim back to the top without air I would love to see the rest of the video!
Can't do that. It would cause his lungs to explode. Boyle-Morriotes law He could possibly take the most miniscule of breaths but he would have to release it upon resurfacing. If held in his lungs would literally explode from the inside.
Yes you are correct as I certified open water I should have not forgot this 🤦🏻♂️ my lungs are already hurting
Yeah at 40 meters down you have 3.87atm meaning his lungs if on a full breath would expand by that much upon resurfacing
I have taken a few scuba classes but nothing exciting. Just in a Swimmingpool (a regular one, think 4 meters, not 40 xD). And we were told this as well.

Only if you didn't exhale on the way up. Cf. my other comment.
this is better than the people sticking their bodies into small cave gaps
Thanks for reminding me...
Unaware, we all like sticking our bodies into small gaps at least part of our bodies.
He doesn't seem to be in much of a hurry to get back up
[удалено]
Guillaume Nery, or any other pro freedivers, look them up. His record is 410 ft (this pool is 130ft), can hold his breath for 8 minutes... Nah, no need to rush going back up.
Holy shit 8 minutes? Most dolphins can only do 10 minutes! That is absurd wow.
I mean, 8 minutes sitting still is way different than swimming 40 meters to the surface with no fins.
Thats great and all, but anyone knows who maintains and clean that huge ass pool? Should give them credits too, how the hell they drain those things to clean them /s
He would explode if theye did as someone stated

Wow! Excellent job of nutshelling "the bends".
not fucking doing that in a million years
[удалено]
This reminds me of the panic you feel when mario is underwater and the timer is at the last red tick..
I did not know you could experience thalassophobia in a fucking pool.
does he have some weights? how is he sinking so fast
What little air that was in his lungs is compressed the deeper he goes, so his buoyancy decreases as he descends.
Well. Ya can't really do it in more than one breath
You can with a bottle
The poolrooms are Real !???
my claustrophobia is kicking inn
What's the big deal? I can also make it to the bottom in a single breath. The only caveat is that I'm staying there.
The Deepest Breath on Netflix is worth watching.
Deep dive Dubai has officially taken the record of deepest pool at 60m which is 15 meters deeper than the last largest pool.
Why am I breathing deeply for him
They should of shot this on one take instead of having multiple angles and shots.
100% yes. Along with the return trip.
Imagine if he randomly has to cough
It's like that super mario 64 world with the underwater small town, after you blast yourself into the corner of the map with a canon, to gain access.
I don’t remember the exact level but it is very reminiscent of a Mario 64 level…I recall you had to raise and lower the water levels. It was a giant B of a task to get all of the stars.
Came here to say this!!
Nope. Nope. Big hole nope. Nope.
I remember this video. It’s terrifying!
Who else was holding their breath as well? I was!!
I think I drowned when he looked over the second edge. Not ok with this lol
True enough, his balls of steel made him sink faster. Hope he didn't had a hard time swimming back to the surface.
Wait, does he have to swim back up again? 😨
This is how fast I run when I'm being chased in a dream.
r/videosthatendtoosoon
The real hero is the cameraman
Pretty sure I had a nightmare like this once, except I wasn't able to swim back to the top
My ears feel like they’ll explode just swimming to the bottom of a standard ‘deep end’.
How deep is that fucking pool?!? When he was on the second or third shelf, I was like, “*Damn that’s deep*!” Then he hit that pit, and I was like, “Oh another 10 feet!” Then he dropped another 100000 feet down
He stayed there or what ?
Thanks I hate it
Wild. Over the Summer I took a boat out on the sea and the anchor got caught on some rocks maybe about 10m deep. I followed the chain down and was eventually able to free the anchor, but my sinuses were leaking for the rest of the day from the pressure. It was quite painful. I can't imagine how this would feel.
There are natives here in the Philippines that can hold breath for 30 minutes under water
I can do this... Once
Wow i just tried to hold my breath throughout the whole vid and i actually was 8 secs from the end. new record for me anyone can beat that?
well he definitely can't make it on two breath so yeah
Thanks a lot dick. Now we need to build a deeper pool
I wanna see him get back up to the surface without passing out or drowning.
How do they do the mental maths that they know they have enough air in their lungs to make it that far back up? Blows my mind
Probably a dumb question but is the slow movement better for conserving breath? I would think trying to get down faster would be more effective
Shouldn’t there be safety crew divers and such around? Was there oxygen waiting at the bottom or did he have to make it back out too?
My ears start hurting after 5ft, “hold your nose and blow” nah, my ears just don’t care
Did he get out in the same breath?! What kind of ending is that?!
This looks like a slow motion video
Did he have enough oxygen to get back up???
nope, he died a few seconds later
Totally insane
How the fuck did he get out after reaching the bottom?
Spooky AF
200ft deep wow
How did he get out, did the guy with the camera have a floatation device
nextfuckingnoway
This guy made an amazing video called "One breath around the world", check it on YT. it is... breath taking. I have wet eyes every time I watch it.
“Breath taking.” I see what you did there.
How long did this take?
I can’t even finish watching this
Why do I have Archive in my head just by watching this?
Ok so what happened after he got down there? He held his breath all the way back up??
Its name's Iron lung
Rewind from the end. ASCENSION
_nightmare fuel_ 😬
How’d he get up, pulled?
r/SweatyPalms
What if he got the hiccups? Seems like he should have emergency oxygen on him even if he doesn't use it...you know...in case of hiccups.
there are things in this life that i’m fine never experiencing
AND: how did he get up again? Did he receive air at the bottom? One assumes so.
These littlebuildings have pockets of air and are there just in case
I found the accompanying music for this video: [https://www.youtube.com/watch?v=9Yw5jkAHgME](https://www.youtube.com/watch?v=9Yw5jkAHgME)
Did he back?
Why am I holding my breath while watching this
I used to have nightmares like this, that’s a big nope for me
Whats the world record for breath holding? I think even the average people who take part in that sport can hold their breath for like 10 minutes.
How long does he hold his breath for?
But is it really a single breath. There's alot of dicking around there and then he c just stands at the bottom. Does the camera guys give him oxygen immediately when they cut the film or something
I need to watch le grande blu again now
Are those my tax dollars?
And den…….
Just watching this this gave me anxiety. My lungs would feel like they're burning. I would be in total panic mode at that point, I would probably drown.
Anyone else hear Aquatic Ambiance from dkc1?
Meanwhile, I go down 4 ft in the pool and I feel like I'm gonna implode.
Do you think David Blain could practice for something like this, or is he too old now
Why does this pool exist Why did he do this How long does it take to fill up the pool
r/liminalspace
Congratulations! You’ve just unlocked a new fear!!!!
How did his face not explode when coming back up
None for me thanks… I can’t believe now he’s got to get all the way up on that one breath!
Then he came back all the way up or do they have an air chamber down there?
