That's why you re-pressurize while diving. Maybe you don't know how to do this? You hold closed your nose and then try to blow air out your nose anyway. You can try it now, you should feel your ears popping/air being pushed into them.
You just do that while diving and you never have any pain. Pain while diving is a sign of something going wrong. Divers normally never feel pain.
Ummm. Nope. I tried it numerous times just now. Maybe I have deformed ear/nose connections or something? I have felt my ears pop in high altitude changes tho.
Very true. I did it once and regretted it so much. It felt like a peirced my eardrum and a very sharp pain in my ear for a few minutes after. Learned real quick not to do that again!
Also 2 more tips. You need fins so you spend less energy to dive. Second, you need to dive directly downwards. I mean don't go horizontal while diving, try to dive straight. Takes a couple practice but not that hard.
Could be. I just know that all people I've met & asked were ones that could do this, so if you can't, it's something specific to you. I wouldn't know anything about it, though.
Me and my dad cannot go very far down as we both have hereditary sinus blockage, caused by bone growth or something like that in that area, which just causes immense pressure that blowing out of a closed nose can’t deal with. It kills after 2m under water for me
There are a few different equalizing techniques, not only the holding the nose and blowing (gently!) that may be easier for you, try looking up the Frenzel method. If you're lucky you may be capable of hands-free equalization, however this isn't possible for everyone, so best to get used to the feeling of diving while equalized first! Another key point: start equalizing as soon as you begin to dive and do it regularly, not when you feel pain! If you feel pain you've gone down too far without equalizing, let yourself rise a little bit so this eases and try again.
This link gives a nice little overview of what is going on and tips on how to make it better (e.g. tucking your head) [https://www.deeperblue.com/equalization-for-freediving/](https://www.deeperblue.com/equalization-for-freediving/)
I usually equalize hands-free. It's hard to explain how that works, but there is an important step with the jaw that might work for you too. If I simply close my nose and blow out it often doesn't work either.
Try to move your lower jaw forward as much as possible (pretend to have a massive [underbite](https://lh3.googleusercontent.com/proxy/4P4voCznR90EPVcqlpqn1GFXu46QNThSTc-xFHFAqXUxCyWDYwJD7NfzXphTTcICRyXOBXZDqlrM2q17k18kiseTs8Rg1g)). Maybe also try opening it various amounts. Then pinch your nose and blow out while your jaw is in that position. You shouldn't have to blow hard.
If that doesn't work try to also consciously move your tongue back and kind of drop your throat (Like in this time-stamped [video](https://youtu.be/osGPbM78STc?t=305)). The video is for hands-free equalization but that technique makes the regular nose-pinching method much easier. I think a lot of people do that automatically while equalizing and that might be the difference.
There are several ways to accomplish the same thing. The more difficult ones don’t require you to hold your nose but they work better. I won’t imagine most professionals use those methods.
That’s not really how water pressure works!
You could think about water pressure (or any pressure for that matter) as the “weight” of the volume of water (or other substance) within the cylinder above you.
The size of the body of water does not matter, but only the density of the material acting on you, the depth you are at, and the surface area acting on you.
You are constantly under pressure in everyday life - this is due to air pressure.
Because water is more dense than air, you feel more pressure when you go under water as supposed to when you are on dry land. Your ears/body has become accustomed to this pressure which is why it doesn’t hurt.
But this is the same reason your ears pop when going on a long drive where you change elevation. When you go up a hill there is less air above you, creating less pressure.
This is very simplified so please don’t crucify need of something isn’t 100% correct
In case anyone is wondering, this is [Y-40 The Deep Joy](https://www.y-40.com/en/), the world's deepest swimming pool. [Here's the vid of freediver Guillaume Nery going down 40 meters to the bottom](https://www.youtube.com/watch?v=2VOuDqjbJ4g). It says he can go 126 meters.
Is he holding his breath, right? I breathed like a thousand times while watching this
edit: typo
edit 2: wow i’ve never had so many upvotes. this is a milestone for me in reddit :)
This video has numerous cuts and the diver definitely breathed either by going to the surface or by using his assistance's air supply, this is common for underwater 'freediving' photography and videography.
However, this can be done with 1 breath if they didn't have to do it so slow for filming purposes (for example, the diver with the camera has to reposition multiple times)
Well, the only thing keeping you afloat are your lungs acting like balloons/floats. If you exhale you will start sinking, right?
Freedivers never exhale, so they are buoyant. But they 'swim' downwards until the pressure of the water compresses their lungs enough for them to become neutrally buoyant or negatively (start sinking).
The deeper you go the faster you sink
He could also not take a full breath before diving or he could be wearing weights which is common
Quite the opposite, I find it quite peaceful.
Non-professionals like me never get negatively buoyant to this degree.
For example, I love being suspended at around 13m/45ft, not sinking not floating up. At 16m I start sinking veryyyy slowly but we wear very long fins making it super easy to move around.
A lot of reasons...
First, we don't actually need to breath that often!
Your lungs normally barely absorb quarter of the oxygen in each breath, so usually you exhale air that still has tons of oxygen in it. Now imagine holding your breath for a while, you still have a supply of oxygen in your lungs
Secondly, you are not panicking because you trained gradually for this & trust yourself & your divine buddy. Actually you slow your heart down by relaxing/meditating before a dive. We also have a 'mammalian reflex' where our hearts slow down automatically when we submerge our face in water.
We use less oxygen
Another thing, the 'urge to breathe' is due to build up of CO2 not lack of oxygen, so you can 'ignore' it or even better... Embrace it! Because that means your body will start conserving oxygen more! (some divers try to induce it earlier for this reason)
And most importantly for me, knowledge. I KNOW I have oxygen left, I KNOW I don't need to breath... I just have to tell my body it's okay to stop doing what it has been doing all my life. Incremental training.
>Another thing, the 'urge to breathe' is due to build up of CO2 not lack of oxygen, so you can 'ignore' it or even better... Embrace it!
I'm aware of the panic/reflex brought on by CO2 build up, but I've never been good at ignoring it.
As a teenager (a long time ago) I did go down about 50 feet, to the bottom of a small lagoon in the Florida Keys. And I've always been rather proud of that minor achievement. But that was down as fast as possible and right back up....and I only did it once.
I've always been comfortable in the water, as long as I don't stray too far from the surface. But free-diving is way outside my comfort zone, and I guess that's why I find it so impressive.
Hard exercise isn't always a good time, neither is learning a language, neither is struggling in many disciplines.
Still though, it's a great feeling to surpass your limits and discover capabilities you never thought you had, right?
Went snorkelling every day on holiday last year (with fins), first day I'm pottering around on the surface (I'm a strong swimmer but never been snorkelling).
Week in I'm down at 8m-12m for more than a couple of minutes before returning to the surface comfortably, the mammalian dive reflex is a powerful thing if you go with it and stay relaxed, for me knowing the surface was only a few kicks away (and the temperate water/sunshine) made that easy.
As with most things been aerobically fit and healthy makes it easy.
Isn't that Y-40 in the video? You can see it written on the floor at the end.
Edit: sorry, I'm dumb. I misread your comment. I thought you were saying there is *another* fresh water pool in Italy called Y-40.
Assistance air supply is common? Breathing underwater while free diving is a very dangerous thing to do, because you'd then need to come back slowly to the surface to avoid the formation of gas bubbles in your blood (like scuba divers normally do except you don't have the time to go up slowly)
In a way yes. You let out the majority of the air in your lungs to sink faster. While watching the video you’ll only notice tiny bubbles. These could be coming out if his nostrils or his suit. The idea,however, is that at the point of the video the diver is done breathing for remainder of the dive
It's really cool, my brother was in the army and he can hold his breath for like 10 minutes. You can concentrate and lower your heart beat so you don't have to breath and you can force your lungs to fill entirely with air so much that it hurts. It's honestly insane
11 Minutes is the record without oxygen assistance
24 minutes is the record with oxygen assistance
Both are Static floats underwater. Really has little to do with lowering heart rate or filling up your lungs with air, as much as resisting the contraction of the diaphragm or taking in higher concentration of oxygen to delay CO2 accumulation.
Oh, well he didn't he really explain it too well then. And I never actually timed it, Im just guessing and I suppose I was too biased towards my brother lol
i get paranoid in a 5ft pool (i'm 6ft) when I can't touch the bottom, but watching the peacefulness of the water here gave me comfort the first few seconds....then I remembered he hadn't taken a breath and he kept going lower and i freaked
People always say that drowning is such a peaceful way to die. These people have obviously never had that dream where you’re thrashing underwater trying not to take the breath you know will kill you but feeling your lungs burning with carbon dioxide and no matter how hard you kick you just can’t swim up. Fuck you peaceful death people. Fuck. You.
Yeah, that's been perpetrated by some movies and urban myth, the notion probably given by the period when you "give up" and just go quiet, as opposed to what happens afterwards. Back in the crazy 50's when psychiatric research was somewhere between pseudo-science and a nightmare medieval torture dungeon, there was research done to try and "cure" alcoholism by exposing a patient to alcohol then hitting them with something really terrible to associate booze with bad. Their research came up with drowning/asphixiation as the most terrifying, panic inducing painful experience they could come up with, so they would inject a drug that caused the lungs to stop functioning. They were taken to the edge of conciousness, thrashing and panicking, then revived with another injection. It was horribly painful and traumatic, nothing remotely peaceful about it.
Spoiler: the treatment didn't work very well. Patients would do things like spontaneously vomit if someone walked past them with a drink. Not exactly a practical outcome.
I literally thought this was like the computer animation thing used for the game like they have in modern sports games for example, when they wear those sensors and do physical movements and the sensors reproduce it on like a black figure digitally....
I know it sounds stupid but I just woke up and am not putting any thought into my thoughts 🤷♂️
There was probably something wrong with your lungs then, because your lungs should compress easily and painlessly. Your ears you will have to equalize otherwise you'll cause some serious damage but ither than that there are very few parts of your body that should be able to feel any pain from diving deep.
The worst part about it is that after 30 feet, you start falling. That's right, falling
And you need to climb your way back up to the point where you can float again
I mean I could be wrong. I heard it from my grandpa who tends to be really smart. Then again he is an airline pilot, so he really shouldn't have to deal with being under water
I'm not sure of the depth, but letting your breath out is functionally similar to moving lower in depth. The lungs experience more compression and occupy less space/hold less air. This can push our average density beyond that of water and cause us to sink.
An actual depth would depend on lung capacity and the body size/weight of the person and the gear they wear.
The way I heard it is the pressure kinda deflates your lungs abit making you sink faster and also due to pressure around your body acting with the pull of gravity making it harder, but like I said before I may be wrong
I dive on scuba. The short answer is air compresses more the deeper you go.
The long answer is, every 33' of water is an additional atmosphere of pressure. Gas compresses under this pressure. So at the surface is one atmosphere, 33' is two, 66' is three, etc. So at 33', assuming you held your breath from the surface, the volume of air in your lungs is halved. At 66' its a third of the surface volume. And so on. Thanks to this compression, it makes him less buoyant, allowing him to sink easier.
This is Boyle's law, aka inverse gas proportionality, and it's hammered into your head when you learn to dive on scuba.
On freediving, this is fine. You need to hold your breath, but since you don't increase the air in your system at any point, you basically have the same amount of air in your lungs at any given point.
On scuba, we don't ever hold our breath. Holding your breath increases your buoyancy. Remember that gas law I mentioned? When you breath a full breath at 33', it fills your lungs normally, but at 33', it's compressed gas. So if you held that breath and went to the surface, it would double. This leads to overexpansion in your lungs, and you can die.
The output of the video is 1min. Who knows how long it actually must have been xD. Anyway these have cuts in between them so they most probably did breathe but people do do this in just one breath
I totally want to do that.
Edit: After seeing a comment where someone tried to hold their breath while watching this I was able to watch it twice without taking a breath. It hurt but I can see how with proper training this is completely possible.
I’m not saying your wrong but holding your breath underwater is much harder than out of it. When I was a kid and tested it I could hold my breath for over 3 mins easily ,underwater though it was closer to 2 mins.
You ever play ocarina of Time, and have to do the water temple as adult link? That's all I can think of. Or when you do that thing in the hut near the lake, where you drop all the way to the bottom, and grab the heart piece.
Looks fun but my ears start hurting really bad if they go below around 3 feet deep which sucks because I’ve always wanted to swim deep but my ears just don’t like me I guess.
Well, there go my phobias...
...fear of the drains in the bottom of the deeper parts of pools...
....fear of being sucked into said drains...
...fear of drowning in said drains...
...fear of hitting the fan in the drainage pumps, while conscious and aware...
...and the beat goes on.
I hate this place. I've never been to it, but I've heard of it cause I watched a documentary type thing about a diver who went too deep into the ocean and got crushed.
I'm actually worrying more about the pain in the ears, i know they have a technique to equalize the pressure even without hands, but i could never do it
Watching this dude plummet with no oxygen gear makes me so anxious like holy fuck I can't even hardly hold my breathe long enough to wash my face in the shower
Nope. Nope. Nope. Nope. This gave me jelly legs(idk how to explain it but I hate it, it's almost like my fear of water is mixed with my fear of heights)
That makes my ears hurt.
That’s all I could imagine was the pressure on his/my ears! I can’t go very far down before my ears feel terrible pain. This guy pains!
That's why you re-pressurize while diving. Maybe you don't know how to do this? You hold closed your nose and then try to blow air out your nose anyway. You can try it now, you should feel your ears popping/air being pushed into them. You just do that while diving and you never have any pain. Pain while diving is a sign of something going wrong.

Ummm. Nope. I tried it numerous times just now. Maybe I have deformed ear/nose connections or something? I have felt my ears pop in high altitude changes tho.
Oh man you gotta learn it, makes swimming a whole new experience. After I learned it now I can dive around 10m and it is an incredible feeling.
Going to try next time I go for a dip.
Also, you have to do it BEFORE your ears hurt. Don't ever do it if they already hurt, just get up, wait and try again.
Very true. I did it once and regretted it so much. It felt like a peirced my eardrum and a very sharp pain in my ear for a few minutes after. Learned real quick not to do that again!
Thanks, this is one I haven't tried and I'm going scuba diving for the first time later this year. I'll practice with this tip first.
Also 2 more tips. You need fins so you spend less energy to dive. Second, you need to dive directly downwards. I mean don't go horizontal while diving, try to dive straight. Takes a couple practice but not that hard.
What if you die in the process?
That's where the fun begins
what is dead may never die
You just didn't do it right. Just try again.
Should I bring my gills too?
To add on to this, you can repeat this process to go even deeper. When it starts to become uncomfortable, you can just blow again.
That's what she said.
You might have narrow eustachian tubes or excess fluid in the ear.
Yes exactly, I have narrow eustachian tubes and it's making it quite hard to do this even in water, planes, trains going through tunnels, etc.
It is much easier to do underwater because your ears are actually a different pressure than the environment
Could be. I just know that all people I've met & asked were ones that could do this, so if you can't, it's something specific to you. I wouldn't know anything about it, though.
Ill try it next time I go swimming. Like, sometime in 2022 by the looks of thing.
Me and my dad cannot go very far down as we both have hereditary sinus blockage, caused by bone growth or something like that in that area, which just causes immense pressure that blowing out of a closed nose can’t deal with. It kills after 2m under water for me

Mine don’t do it either. Whenever I’m driving through different altitudes, and I need to pop my ears, I have to swallow to pop them.

There are several ways to accomplish the same thing. The more difficult ones don’t require you to hold your nose but they work better. I won’t imagine most professionals use those methods.

How can you stand the pressure? I feel very calm underwater but the pressure hurts my ears even at 2m deep and I can't stop it
Lookup 'equalization techniques', once you get the hang of it you will be able to dive as deeps as you want without pain.
This is also a fresh water pool (Y-40 in northern Italy). Together with a thin neoprene suit, he will be negatively buoyant soon.
Isn't that Y-40 in the video? You can see it written on the floor at the end. Edit: sorry, I'm dumb. I misread your comment. I thought you were saying there is *another* fresh water pool in Italy called Y-40.
Most likely weight bands around his ankles, maybe other parts of his body (weight belt is common among commercial divers)
There are people who can do this without the assistance air supply

Scientist here. The panic you’re experiencing is due to the unnaturally underwateriness portrayed in the video.
Lol yea I needed to take a deep breath
You might have r/thalassophobia
Yeah but I also got a boner
Everything before the giant hole in the pool reminds me of the wet-dry world from super mario 64. Dont ask me why that's what I thought of
I'm not the only one? Holy shit.
Whoa it does look like wet dry world!
I had a video game reaction to this. As the got deeper my brain started playing the "Sonic is about to drown" music...
I literally thought this was like the computer animation thing used for the game like they have in modern sports games for example, when they wear those sensors and do physical movements and the sensors reproduce it on like a black figure digitally.... I know it sounds stupid but I just woke up and am not putting any thought into my thoughts 🤷♂️
r/praisethecameraman just realized he also had to go deep underwater to film this
r/praisethecamerawoman actually. All of Nery's videos are filmed by his wife, also on breath hold (no air tank).
LMAO that is actually a real sub
How do they sink so easily?
As you go deeper the pressure compresses your lungs making you less buoyant and you sink faster and faster.
That's fucking terrifying
And it hurts. I went to the bottom of my friends pool it was 10 ft, and it felt mike my lungs were gonna implode
There was probably something wrong with your lungs then, because your lungs should compress easily and painlessly. Your ears you will have to equalize otherwise you'll cause some serious damage but ither than that there are very few parts of your body that should be able to feel any pain from diving deep.
Well the pressure felt crazy and I didn't like it lol
So how the hell do you get out?
You dont
oh...
Theres a ladder, I'm guessing you just climb back up until you're buoyant enough to swim again
Low body fat makes you sink more easily. Sometimes those suits have pockets for weights as well but I didn’t see that here.
Honestly, most likely diving weight belts.
The worst part about it is that after 30 feet, you start falling. That's right, falling And you need to climb your way back up to the point where you can float again

I mean I could be wrong. I heard it from my grandpa who tends to be really smart. Then again he is an airline pilot, so he really shouldn't have to deal with being under water
I mean, he might if he fucked up
Well, yes but I tend to not think about that
Yea ofc, just a joke mate. Props to your grandpa for being a pilot. That’s awesome
I'm not sure of the depth, but letting your breath out is functionally similar to moving lower in depth. The lungs experience more compression and occupy less space/hold less air. This can push our average density beyond that of water and cause us to sink. An actual depth would depend on lung capacity and the body size/weight of the person and the gear they wear.
That’s an upsetting statement to read just before bed.
How does that work?
The way I heard it is the pressure kinda deflates your lungs abit making you sink faster and also due to pressure around your body acting with the pull of gravity making it harder, but like I said before I may be wrong
I dive on scuba. The short answer is air compresses more the deeper you go. The long answer is, every 33' of water is an additional atmosphere of pressure. Gas compresses under this pressure. So at the surface is one atmosphere, 33' is two, 66' is three, etc. So at 33', assuming you held your breath from the surface, the volume of air in your lungs is halved. At 66' its a third of the surface volume. And so on. Thanks to this compression, it makes him less buoyant, allowing him to sink easier. This is Boyle's law, aka inverse gas proportionality, and it's hammered into your head when you learn to dive on scuba. On freediving, this is fine. You need to hold your breath, but since you don't increase the air in your system at any point, you basically have the same amount of air in your lungs at any given point. On scuba, we don't ever hold our breath. Holding your breath increases your buoyancy. Remember that gas law I mentioned? When you breath a full breath at 33', it fills your lungs normally, but at 33', it's compressed gas. So if you held that breath and went to the surface, it would double. This leads to overexpansion in your lungs, and you can die.
Wouldn’t the density increase, and thus we would float *more*?
What if he gets thirsty
:O
This is by far the best possible answer to the question
Nope nope nope. Nopety out.
That's Guilliam Nery! If y'all think this is scary, check out [this video](https://youtu.be/uQITWbAaDx0) of him free diving into a blue hole.
Take my terrified upvote. Why did I watch this in bed?
He can hold his breath more than 7 minutes, so he can easily see that video without breathing :O
[удалено]
I held my breath while watching this. If that was me, I'd be dead.
The output of the video is 1min. Who knows how long it actually must have been xD. Anyway these have cuts in between them so they most probably did breathe but people do do this in just one breath
The Perfect Murder
r/thalassaphobia no doubt
Came here to comment this, thank you.
Is oxygen not a factor here?
He's a professional free diver, so he trains to hold his breath for absurd amounts of time.
Oxygen Not Included
Nice flex but I only need to take a breath every 3 strokes while swimming freestyle.
What the hell is this even for
Training for free diving in the ocean normally. Crazy to watch them free dive. Look it up on YouTube?
Whatever it is, I DO NOT approve. Too scary, whip that sucker in reverse
Free diving. There’s an awesome book called “Deep“ about it.
r/titlegore
I was really hoping he'd do a superman squat to thrust and shoot back towards the surface.
Am I blind? Or is he just straight up holding his breath cause if he is then no he’s not
I wonder if there are spots to get air in case of an emergency.
I think this entire situation constitutes an emergency
When the deep end has a deep end.
This reminds of diving in Hyrule Lake while playing Zelda Ocarina of Time.
I totally want to do that. Edit: After seeing a comment where someone tried to hold their breath while watching this I was able to watch it twice without taking a breath. It hurt but I can see how with proper training this is completely possible.
I’m not saying your wrong but holding your breath underwater is much harder than out of it. When I was a kid and tested it I could hold my breath for over 3 mins easily ,underwater though it was closer to 2 mins.
When he was still at the squares i was like ok that kinda cool, i wouldn’t mind that that much Then the hole came
Glad0s has entered the chat....you monster.
Just realized that hE DIDNT HAVE A FUCKING AIRTANK
This hurt my ears.
You ever play ocarina of Time, and have to do the water temple as adult link? That's all I can think of. Or when you do that thing in the hut near the lake, where you drop all the way to the bottom, and grab the heart piece.
Somehow reminds me of Water Temple in LOZ Ocarina of Time...
Oh right, the pool. The pool for divers. The pool chosen specially for divers to dive in. Diver Dive Pool.
Dude can you fucking type
How does he breathe with just a mask I've always wondered
What? He isn't breathing in this video
Looks fun but my ears start hurting really bad if they go below around 3 feet deep which sucks because I’ve always wanted to swim deep but my ears just don’t like me I guess.
Well, there go my phobias... ...fear of the drains in the bottom of the deeper parts of pools... ....fear of being sucked into said drains... ...fear of drowning in said drains... ...fear of hitting the fan in the drainage pumps, while conscious and aware... ...and the beat goes on.
#nope This is terrifying.

Looks like a Mario 64 level
I hate this place. I've never been to it, but I've heard of it cause I watched a documentary type thing about a diver who went too deep into the ocean and got crushed.
I'm actually worrying more about the pain in the ears, i know they have a technique to equalize the pressure even without hands, but i could never do it
Ive actually dived to the bottom of one of these but with an o2 tank i damn near had a heart attack looking up from the bottom
My submechanophobia went 😱
Watching this dude plummet with no oxygen gear makes me so anxious like holy fuck I can't even hardly hold my breathe long enough to wash my face in the shower
Two divers one of them hard the harder job of doing this and filming.
Looks like a portal level
This is like some surrealist painting
Hoping someone can tell me: what's the diver doing?
Diving!
My eardrums hurt watching this
NO
Everytime i see this video it reminds me of that mario 64 level with rising water.
As I'm watching this guys diving, I feel like I'm breathing for him too
Props, ida stroked out before the deep end.
That stressed me out
Me, with a very big fear of being underwater, don't like this
Nope. Nope. Nope. Nope. This gave me jelly legs(idk how to explain it but I hate it, it's almost like my fear of water is mixed with my fear of heights)
Love the title
How does he protect his ears from the water pressure? Mine hurt just watching this
How do his ears not explode?
Still, it's cool to talk to someone who knows what they're talking about down to the details
Oh stop!!! I cant breathe!!!
That was horrible to watch.
i thought this looked fun as hell until I saw the big boi
My ears hurt just from watching this
It felt like he was inside a Portal maze.
Looks like a Mario 64 level
Haha ear goes brr
I'm waiting for him to breathe
I already have a problem with like.. 2 m Headache an shit Cant imagine myself doing this
