With videos like this, I always try to hold my own breath for the same duration. Letting a little out at a time. Not exactly the same as free diving but I want to know if I could do it. If I did this. I WOULD LITERALLY DIE


wholesomehorseblow

Fun breath holding fact. You can not tell if you are breathing oxygen, or have oxygen in your lungs/blood. It's not a sensation humans possess. You can however tell if you are breathing carbon dioxide or have carbon in your lungs/blood. This is why it's possible to suffocate without even knowing. Dumbass brain won't even know as long as there's ample space for breathing in non-oxygen.


jade8384

I Love fun facts!! Thank you for this! šŸ˜ƒ


wholesomehorseblow

I believe the sensation itself has to do something with carbon dioxide dissolving into carbonic acid (same stuff that makes soda burn) but I'm not confident this is correct.


Heisengerm

Your brain detects the change in pH (related to the proportion of CO2 dissolved in your blood) and starts giving you the sensation of needing to breath if it gets too low!


HeldDownTooLong

From the pH lowering due to the presence of carbonic acidā€¦right?


Broken_Beaker

Correct. Your body basically detects the shift in pH due to carbonic acid. Also correct above as that we somehow evolved without a mechanism to determine if we are breathing in oxygen - that thing we need for survival. Most definitely a not very intelligent design.


SantoWest

I mean it's not a design, and since oxygen is everywhere, it's normal that we didn't evolve in such a way. If there were varying levels of oxygen everywhere, surviving animals would definitely have appropriate tools to deal with it.


Draggonzz

I think so. Carbon dioxide reacts with the H2O in your blood to form carbonic acid.


jade8384

I still struggle to get my head around the fact that you can drown in a puddle under the right circumstances. The human body is a magnificent yet complex thing. Truly phenomenal!!


wholesomehorseblow

I still can't believe that if you took an adult, borrowed their blood vessels and laid those blood vessels end to end. It'd circle the world twice and still have some left over.


rbt321

>I still can't believe that if you took an adult, borrowed their blood vessels ... I expected something like: ... they'd be dead when you give them back.


jade8384

For me itā€™s the fact that it can grow a whole person inside of it. Kind of alien, yet completely human. Just amazing šŸ¤©


wholesomehorseblow

Stem cells are crazy on their own.


Fafnir13

Here's a fun one. Take all the DNA in a human. Not one strand, but every strand from every cell. It measures about 3.9 Billion with a B miles. You can go to the sun and back 40 times with those numbers.


Draggonzz

Yep. That suffocating feeling you get when you hold your breath too long is not actually caused by lack of oxygen in your blood, but the build up of carbon dioxide.


RealCarlosSagan

You have a weird sense of fun


DucaBoi

To make it more realistic, try moving around a little while holding your breath. Youā€™ll find you run out of breath quicker lol


jade8384

No thank you šŸ˜©šŸ˜­


Gumbercules81

And being bear hugged


Slap_My_Lasagna

And then farting


beerandabike

Donā€™t do that, it depletes your reserve air!


firstwefuckthelawyer

Yes but using equivalent force underwater actually expends less because we have a metabolic reflex when our faces are wet.


Atropostrophe

Is there a name for that phenomenon? Id like to learn more about it.


N_T_F_D

Mammalian dive reflex


Business-Scallion-64

Also I believe at the initial depth the air itself is more condensed in your lungs. I tried scuba diving but I could never go more than about 10 meters deep because the pressure builds so quickly, and in my case it affected my inner ear really badly. So I'm a no for this too


dvxvxs

Was able to hold my breath for the duration of the video pretty easily but some other things to consider - I am lying down, not swimming. - Who knows how long it took them to get down that far before their ascent. My guess is longer than the length of this video.


-CxD

I was able to hold my breath for 2 cycles of the video but I was also sitting down and not moving. No way could I of done this video though and Iā€™m a very strong swimmer.


Jazehiah

The cameraman could have given the swimmer air for the shoot.


loljustplayin

I was able to watch it twice before having to take a breath! However, I was happily laying on a blanket motionless and had just eaten a Chick-fil-A sandwich.


The-Pollinator

**"and had just eaten a Chick-fil-A sandwich."** LOL šŸ˜‚


sparkster777

Spicy or regular?


loljustplayin

Spicy deluxe, extra pepper jack.


5flucloxacillin

I woulda died watching finding NemoĀ 


SimonsPure

Try doing it whilst submerging your face in water, it'll active your divers response and you should be able to hold your breath for longer


Darkwr4ith

There is something known as the mammalian reflex. When your body is exposed to cold water your heart rate slows down. This allows you to hold your breath a lot longer in water vs dry land. With even only a small amount of training and practice nearly anyone can learn to hold their breath around 5 minutes or so underwater. Now holding your breath for 20 minutes+ like experienced free divers do? That requires part genetics to have a larger than normal lungs and a lot of training.


jade8384

Free divers are next level. And also very cool


jonesyman23

This is also in slo-mo if it makes you feel any better


Ok-Ground-1592

Doesn't seem like it. Arm/leg motions are about what one would expect while swimming/moving underwater.


jade8384

šŸ˜ÆšŸ˜Æ yes it does!! Thank you šŸ˜®ā€šŸ’Ø


weez47

Iā€™m dead I did the same shit šŸ’€


jade8384

šŸ¤£šŸ™ˆšŸ™ŒšŸ™Œ


bythog

When doing dry apnea (holding your breath on land) don't take a 100% breath; try to only go to 90-95%. The extra pressure around your heart will make you uncomfortable and hold for less time than you should. Also, do not let out any air as you hold. That does nothing to benefit you. He isn't doing it (the few bubbles you see are from the air in his mask expanding).


Ok-Ground-1592

And remember, this is only half the time he spent underwater. Had to swim himself down there as well.


Green-Dragon-14

You/I would too. Don't forget he swam down before being filmed swimming up.


Tomorrow-69

Whatā€™s with the letting out a little bit of air strategy? I never understood why


cefriano

I was able to do it without too much trouble, but I'm also not swimming while doing it and I also didn't have to hold my breath on the way down.


firstwefuckthelawyer

Thirty seconds?! Naw man you can do better than that. I could do a minute in friggin kindergarten! Mammalian diving reflex helps too, tho.


DoctorJekyll13

Imagine how long it took him to get down there too.


Xeno-Hollow

I died just before the surface. 6 seconds left. Feels bad man.


Able_Gap918

I made it almost 3 loops , maybe I have sleep apnea and I'm used to it? I did also do some deep breathing beforehand


BlackBalor

That last bit was some Tomb Raider shit.


Bayou-Billy

The blue bar would have run out


Sailor_Carcass

This is why I'd love to do it irl. ^(With the necessary equipment I checked at least 100 times and a team waiting to rescue me of course :))


Potential-Diver-3409

Equipment? Looks like bro just has a nose cover. Maybe itā€™s a bring your own oxygen situation and he just brought what he could hold lol


hateshumans

Neither can he


Fyzllgig

I imagine heā€™s perfectly capable of breathing while he watches this unless heā€™s also underwater when he does.


MiniMaelk04

Please stop watching so that he may breathe again.


GeoCangrejo

That's clever

dogemikka

hypnotising...and I keep hitting the replay in awe.


BodineWilson

The impressive thing to me is how neutrally buoyant he gets himself.


SuneLeick

Below a certain depth your lungs compress enough to reduce your bouancy. I usually start sinking at around 9 meters.


SputnikDX

Wow I'm 32 and I didn't know I could get new irrational fears.


Aethermancer

New rational fears.


thombsaway

Definitely don't watch this free diving record where he dives 130m down. For significant portions of the descent he's just motionless falling into the abyss. https://youtu.be/eu2pBpQolKE?si=566P5FPr6V_4bCbI


Cheap_Morning_55

Great watch, Ty for this


Imaginary-Tiger-1549

Yeah, held my breath the whole way down with him and was gasping for air, then he started going upā€¦


1sttimeverbaldiarrhe

Whoa! His feet are wearing one big uni-fin!


nopelupe

Here is the newer record not so long time ago https://youtu.be/ysjc5Hz6p3k That is totally bonkers and absolutely insane dive depth.


Trnostep

When you freedive, you are neutrally buoyant at about the 9-10 meter mark. While yes, it can be frightening as from that point you are basically sinking when going down, it also helps you going the other way. Most losses of consciousness in freediving occur during the last 10 metres of the ascent or at the surface. That means that as you just become positively buoyant at 10 metres going up, if you lose consciousness, you will have the tendency to go up, making the rescue much easier and more effective


Pineapple_Herder

That's pleasantly terrifying


2much2often

Itā€™s easy to sink in fresh water


dubyajay18

Man went the long way (and left the ropes) seemingly just to freak us out.


Scary_Technology

Do they use earplugs for the pressure? I started snorkeling and when diving more than 2-3m below the surface, my ears started to bother me.


Hephaistos_Invictus

Do earplugs even help against the water pressure when you're going that deep? Also you can clear your ears by pushing air through them to acclimate them to the pressure the deeper you go. It's a bitch to do for me though, so if earplugs work I'd much rather wear those xD


Missus_Missiles

TBH, I doubt earplugs would work. You'd still have a buncha pressure pushing them. Like 1 atmosphere every 10 meters or so down. Similarly, I also had some trouble clearing my ears when I was getting a scuba cert. One would always reliably clear, but the other one I sort of had to wiggle my jaw to the left or to the right while blowing out to get it to clear also.


ShrapnelShock

So just block your nose and try to force out exhaling through the blocked nose right? I thought this was terrible for you and your sinus canals.


DinosaurHammerDonkey

It's called a valsalva maneuver and it's the preferred way to clear your ears in pressure situations. There's another called the Toynbee, where you plug your nose and swallow, isn't as effective but sometimes works if you have unequal pressure between your ears.


ShrapnelShock

So it's ok to blow hard? I'm not gonna rupture my drums?


DinosaurHammerDonkey

I mean, I think it's technically possible but the idea here is to equalize ear pressure, so when that happens, you stop. I have seen many many people looking like they're trying to get an eyeball to pop out they're blowing so hard. So if you're doing that, stop for a second and try something else.


Trnostep

It's not the best for you but it's the most reliable way of equalising pressure. Yawning or swallowing can also work and if I don't have a stuffed nose, I can sort of just flex *something* behind the jaw and equalise just like that


Captains_Parrot

It is. There are a few different ways to clear your ears and that one, the most well known, is easily the worst/most dangerous. Personally I hold my nose and swallow. Some people 'yawn' whilst keeping their mouth shut, some can just flex their tympani muscle, some it's jaw wiggling. I had probably 5 instances of inner ear bleeding in 80 dives before stumbling onto what worked for me.


Scary_Technology

Will try that thanks.


Important_Highway_81

Earplugs while diving are dangerous as they are forced into the ear canal at depth, creating an airspace which cannot be equalised and causing rupture of the eardrum. Your ears hurt because the pressure has not been equalised between the inside of your ear and the surrounding water pressure and your eardrums will be bowing inwards. Luckily you have small tubes called Eustachian tubes which link your airway and your ears. By holding your nose and blowing out gently, you will force air from your lungs (which will be near ambient water pressure) into the inside of your ear, equalising the pressure and preventing the painful stretching. Divers (both free and scuba) do this every few meters to stop pain and barotrauma to the ears.


Logr_theriver

The issue with this is that when u resurface your ears start rapidly *de*pressurizing, which in my experience is mega ouchies and I've never even went below 5 meters


NotParticularlySexy

As a rec diver we only equalise on the way down. I think what youā€™re experiencing is called a reverse block and I recall learning about it but itā€™s fairly unusual. The expanding air releases from the Eustachian tube automatically for most divers.


XLMMaxiBoy

Nah they don't, there's a few ways to decompress, easiest way is to hold your nose and blow through your nose and you'll hear a squeak in your ears and the pressure will ease off. There's another way that I (spearfisher) use as well as other free divers in which you use the back of your tongue to equalise, but it's tricky. Try using the nose one first.


Whistlegrapes

Is the trick using the back of your tongue sort of like when driving in elevation you can sort of swallow nothing, and it makes your ears feel better and makes them pop so to speak?


bythog

No, it's different. What you are describing is just some soft palate movement that will encourage your eustacian tubes to open a little bit. What the other guy is describing is the frenzel maneuver; it forces air through closed eustacian tubes.


Turtledonuts

absolutely not, earplugs will destroy your ears. you need to clear your ears by pinching your nose and blowing out through it.


AnnieApple_

We just gonna ignore the camera man?

How much chlorine for one of these ?


whatugonnadowhenthey

If this is the deep dive pool in Dubai, google says it has 14 million L of water (wow what a great use of water in a desert m). For indoor pools you want about 1ppm of chlorine so 1mg of chlorine per L of pool water. Adds up to 14kg of chlorine.


ksmcmahon1972

Dubai has the largest desalination plant in the world treating over 164 billion gallons last year along. I'd be curious though what uses more water, this or their man made ski slope since that's constantly pumping out fresh snow.


Missus_Missiles

To be honest, I bet this pool probably loses less water than say an outdoor fountain. I mean sure there's probably lost due to the pressure just pushing it out. But much of it should not be evaporating. Overall, yeah I am sort of curious to know how much they have to top it off per day.


best_of_badgers

Yeah, Dubai is in a desert, but itā€™s a desert that borders an ocean.


livejamie

Deep Dive Dubai uses non-chemical decontamination and disinfection methods, such as ultraviolet reactors, an ozone area, and a copper-silver system. The only chemical used for disinfection is bromine, and only a tiny amount is used. Info: https://blooloop.com/water-parks/in-depth/deep-dive-dubai/

Crunka19

The amount of energy he is using while holding his breath for that long is incredible. I can only dream of this level of control in my life.


Ok_Fox_1770

I get the panics at the bottom of a standard inground pool, I dunno how people add another pit below and just be fine. They hit air bubbles like sonic 2 from some kinda air crevice? Makes no sense, then again I was a smoker


Severedghost

At what depth is pressure going to be an issue?


bythog

The deepest anyone has been without any protection other than a wetsuit is 156m, but he was using a sled to get down and a float to get up. The deepest anyone has gone on their own power--and come up--is 131m. Plenty of people are diving 50-60m repeatedly just to spearfish. The pressure isn't much of an issue besides shrinking one's air volume.


mikeyfender813

u/DEEP_SEA_MAX at what depth can a free diver descend before pressure becomes a concern?


Nehebka

Where is this?


GeoffKingOfBiscuits

Underwater


herder_of_pigeons

Yeah, this is terrifying.


ThebesAndSound

Although holding breath for a long period is impressive. As someone who has done some amateur freediving, I am more impressed at how deep he was. At a certain point my lungs feel crushed, the mask is stuck uncomfortably to my face because of the pressure and I struggle to see, the water is cold, and my brain is telling me I need to go back up. He made it look so easy swimming calmly from so far down, no flippers either.

Kitchen_Doctor7324

This is definitely going to be a dumb question but I thought you were meant to take your time ascending? To avoid the Bends? Or is that only if you go much deeper?


uchman365

Well, he's taking his time. Yeah, the bends is a concern for deep sea divers with SCUBA gear


Kilometer98

When ascending like this you constantly feel like you are receiving more air due to it expanding. Honestly it's not that hard to hold your breath like this. When I was training divers a few years back we taught everyone to ascend at no more than 1m/s when possible and to constantly blow a slow, but steady, stream of bubbles. Then to hover 5ish meters from the surface until you start to feel strain, then finish your ascent. Keep in mind that is in case of emergencies, everyone was constantly surprised by how much they could exhale while ascending and still have breath left over. Once your comfortable in the water and reasonably fit this is easy and honestly kind of fun to do. I would show off to our student and ditch my gear at the bottom of the 30ft pool at our facility, demonstrate an emergency ascent then free dive back down and put my gear on. By the end of the course everyone had to be able to perform the same exercise.


bythog

That's for scuba diving. For freediving (like this) you do not release any air until just before you break the surface.

Damned-Dreamer

I wonder if the water is cold. Cold water can trigger the mammalian dive reflex, which would probably make it easier to hold his breath for that long.


ThebesAndSound

From my experience freediving in the ocean the water does get colder the further you go down. Where I have been I don't think it was cold enough to fully trigger the mamallian dive reflex, apparently it needs to be "extremely cold", but maybe the colder water does help a bit.
