Are there any other LIMITS of HUMAN SURVIVAL you would like to see us explore?
Could you do a video on how far underground we can go?
How long can a male last in sex🤣🤣🤣
How intelligent can humans get if u do this can I have a shoutout or not
Long time no see.
No, I can't think of any other LIMITS of HUMAN SURVIVAL.
Everyone playing Subnautica: "Hold my beer"
@Victor Latorre Romero no kidding. I killed a reaper, moved a bit forward with my cyclops and already spotted another with my radar. The dunes isn't so scary with good upgraded seamoth though.
Nah it's all fun and games until you hear ecological dead zone detected
Damn son where'd you find this. Idk why but the reapers will always be the scariest leviathans in the base game, the sea dragon is a joke and the ghost leviathan is only scary in the dead zone
This is real life not a video game......
Iamfour deepest every recorded: good job 👍 you made it into the lost river
Protagonist of game: going to 1700 m deep with 3 oxygen tanks and super sea glide with no diving suit
The diver's head is creeping the heck out of me.

We can see his but crak
imagine being 15 hours in that deep water just waiting to go back up
Actually that’s impossible. He would run out of oxygen
@@FerhatDemiroz what are you talking about😂🤣🤣🤣🤣🤣 why would he run out of oxygen he scuba cylinders
@@maxmock2661 you can still run out of oxygen even with tanks of it and cylinders but 15 hours is not impossible
@@Averagecrackernamedmicheal he obviously had enough scuba cylinders

This is actually incredible. I never knew people regularly worked at such depths. I feel like I got the bends just by hearing some of those depths ! Thanks
Thanks for your comment! Checkout our other Limits Of Human Survival videos and might learn some more 😁
@@DebunkedOfficial that video made me subscribe!
The maximum depth increased rapidly after WWII from about 200M to 400M but after 400M was reached as maximum working depth it has crept deeper at a much slower pace again. Surface fed supply is a completely different game to SCUBA.
Those deep sea workers actually work at tremendous risk all the time. there was a terrible accident in the 80's where their compression chamber explossively decompressed due to negligence by the company. the divers literally exploded like a bomb due to the rapid decompression. if there is a mercy in this, they died too fast to know what was happening.
I feel like this all the time when I watch videos about diving 😖
Oceangate took me here
Everyone : Rushing to the Comments and stuff
Me : Reading the Title...
My grandfather was part of a team in the Navy set depth records with The diving unit mk1
He says he only went to 600 feet and the team went much deeper but oh my God 600 feet after watching the video holy shit grandpa
18 times the normal atmospheric pressure, that’s impressive
This is the funniest comment on this video
Does his back hurt though?
@@dragoonTT you mean 21 times?
I go down 2500 feet live in bell for 21 days
There is something a little bit misleading in the NITROX part of the video in my opinion.
It is suggested in the video that NITROX allows you to dive deeper, which is not the case, rather the opposite actually. NITROX allows divers to STAY LONGER at certain depths without having to decompress in order to get rid of the Nitrogen in your body, which is totally different.
NITROX can be used in many forms but if you use the usual mixes, such as Nitrox36 (though Nitrox32 is more frequent in recreational diving) you should not go deeper than about 29 meters (about 34 meters with Nitrox32) because of oxygen toxicity. And this is a very important safety matter, because you might simply die if you cross the maximum operating depth threshold.
But as far as you stay within the limit, it's safer to dive with Nitrox, as you don't need to be as careful about the time you stay at depth (usually below 20 meters) as with air, because your body aggregates less Nitrogen, thus allowing you to to stay longer.

How many people stopped driving because you can get killed in a car accident?
@@gordonlawrence1448 I’m sorry if you took my comment seriously it was meant as a joke and not to be taken literal. Sorry if I confused you
It is not by chance that they recommended the documentary about surviving the teenager brain after this...
@@gordonlawrence1448 Most divers actually choose diving because of the beautiful aspects of diving.
Most people in traffic choose the car because they need to get somewhere.
It would be easier to quit diving than quit driving in every day life.
Helium doesn't help saturation divers retain heat, the fact that it is so good at conducting heat is actually a detriment as it conducts body heat away from the diver more quickly than normal.
I haven’t watched the video yet, but as a Technical scuba diver myself, the reason they use helium is because they need to DILUTE the amount of oxygen and nitrogen your body absorbs at depth. Here’s what happens: OXYGEN can kill you at depth (oxygen toxicity, causes convulsions among other things which leads to drowning), and NITROGEN is also harmful at depth (nitrogen narcosis)… at extreme depths, you’d get so drunk/high from it that you’d basically black out and end up drowning. Also, too much nitrogen absorbed = huge decompression (deco) times.
And the reason “depth” makes gases toxic, is because depth = more pressure, which means that gases CONDENSE. So you absorb more molecules of gas, in a breath of air, the deeper that you go.
So anyway, the reason they add helium to the gas mixture, is because helium is harmless to the body. It doesn’t “do” ANYthing, but that’s precisely THE POINT. They want you to be absorbing less oxygen and less nitrogen at depth, because at depth, the gas gets CONDENSED. So they add helium to the mix so that your body absorbs the correct amount of oxygen and nitrogen it
Thanks for the video. I am ultimately amazed at how many people it took to figure all of this out. This wasn't an over night, "we'll sleep on this and have the answer in the morning" kind of scenario. This took a LOT of time and deaths.
It’s just lovely how older videos become relevant after one mishap. Yes I’m here after the submersible tragedy.💔
Just today that I have found your channel. Watched your video on what’s are the limits on human survival. Watched the whole vid through. Subscriber earned. I am now going to have a look through your vault of knowledge and see what else I can find. Really good Vids.
I swear CZcams recommends all the interesting content when I should be going to sleep. Just one more i say then just 1 more and 1 more and 1 more......
Amazing video as usual! Please keep making these incredible videos.
BUT! What if you wore a spacesuit to the dephs? They have they're own pressure, Atmoshpere, Plenty of protection from the enviroment, And everything else. Something to think about!
Well you do get atmospheric diver suits, but it's basically like a mini submarine suit, so we thought that was ultimately cheating 😉
Space suits are made for the vacuum.
They don't keep pressure off.
They are called atmospheric suits. Able to maintain normal atmospheric pressures at extreme depths and extremely expensive to maintain and don't have good dexterity as a diver would without the suit.
Very good question! However, space suits are more or less the reverse of those bulky diving suits.
When you go higher up in the atmosphere, the pressure gets lower and lower until your body can't handle it anymore, and a space suit is designed to keep the surrounding pressure by the suit by stopping it from expanding.
When you dive down, the pressure gets greater and greater until ultimately it crushed you. A diving suit prevents this by keeping the surrounding pressure out of the suit by stopping it from imploding.
Hope this helps
As few people said: spacesuits are designed for vacuum= less than 1 atomsphere difference-> less than -1 bar.
While underwater it would need to hold +1 bar for every 10m of depth. so a suit like this have to be much tougher. at this point you might as well use a mini submarine instead.
Why is this recommended to me after seeing the Titan submersible news
What a good way ta start yer morning, watch a quality video, then go annihilate some fireworks.
Super explanatory video, appreciate your work Debunk team!
who came here after Submirine lost ... Titanic
Came to after watching MEG 2: The Trench. Jason Statham literally free dived at 25000ft underwater 😅
Haha same. Ridicilous. The pressure at 5km deep is 5 tons
As a scuba diver this is very interesting... I've been down to 120 feet
I went to 142 max depth and I got pretty damn NARC’d, lol. I definitely recommend trimix if you go below 130… I was lucky I was on a sloped 45 degree wall, and not a straight-up-and-down wall. If I lost control of buoyancy on a vertical slope I would’ve been in serious trouble. Being narc’d is enjoyable tho for sure but it’s also dangerous if you’re on a vertical wall.
On the other hand I think it’s pretty safe to dive to 140 on regular air IF the bottom is a “hard bottom” that doesn’t go below 150 or 160. Such as doing a “wreck dive” where the ocean floor bottom is exactly 152 feet deep.. That way, if you lose control of buoyancy, you at least won’t die and the dive master can always yank you up if you’re acting a fool.
But in general I recommend being a responsible diver lol. Thankfully when I was NARC’d I didn’t do anything stupid, and I ascended (went up) slowly but steadily until I was at 120 feet, and got my senses back. Lol. When you go super deep it can mess with your head
Oh and ironically I just had sinus surgery 2 days ago to make my sinuses better for life/allergies (and also for diving) and I’m on pain meds right now as I’m commenting lmao… so yeah 😂
@@charlesg7926 how's it goin now then
Let's test it out next time i go SCUBA diving
😂😂😂
Are you alive !🙄
With the mammalian diving reflex, there is an increase in systemic vascular resistance via peripheral vasoconstriction, but this would cause an increase in blood pressure, not a decrease. Wonderful video though.
is the increase in pressure made to match that of the water pressing into your body?
KRI Nanggala 402 has reported drown for 850meters deep in the ocean on 22 april 2021 at 3.00pm Indonesian West Time. About 53 people inside expected still alive for next 72 for the rest of oxygen they have.
💔💔💔
It’s 25 april today and we still hope there’s miracle for them to keep alive😞
😞😞
The crazy thing beside this already achieved depths is that the deepest part of the ocean is around 11000m... This is almost 22 times deeper as the record of 534m.
actually its closer to 21 times then 22 as 22 is 11748 and 21 times is 11214m
@@nathanrogers1793 🤓
Wow I didn't expect this :D :D Thanks!
What a factual and interesting presentation! I will be watching it again like I usually do on videos that I want to remember important facts.👍
As a dmt this is a very informative video , it covers the basics perfectly
This is a very phenomenal video. Thank you
8:05 I remember watching a video on a tragedy on one of these. If I remember, the vessel wasn't fully decompressed when a worker opened the door, shredding everyone inside to pieces. 😱😵
"Evolved perfectly for walking and running on land"? Have you seen the rubber bands and paper clips that make up the human foot? Or the wobbly teacup stack nightmare that is the spine? We're evolved adequately at best for walking and running. 😅
We're actually better then most, if not all, other animals when it comes to walking and stamina.
@@tangytim6699 that is certainly true, but the bar is low.
Check out shaolin monks, they push the limits of the human body pretty far, we're actually incredibly versatile if we work at it.
Who came here after Titan from Oceangate?
One remark, sign NITROX on dive tanks... In underwater diving, nitrox is normally distinguished from regular air, used for regular scuba diving.
Divers marking tanks with Nitrox mixes with oxygen proportion over regular 21%, like nitrox-32, nitrox-36 & etc.
Titanic submarine brought you here
The titanic submarine has sent me down a 2 week long rabbit hole to everything from sonar pings to the mammalian diving reflex😂😂
The video neglects to mention that oxygen becomes toxic if you breath too much of it (at high pressure). Around 223 feet, you come at risk for being poisoned by the oxygen of breathing regular air mix Scuba gear, and much sooner if using NITROX mix (because it has more oxygen).
223 feet isn’t a hard limit, so there is no need to tell about the time your uncle dove to 260 feet. It’s just that beyond this, you risk convulsions with zero warning, which, at that depth, is going to be hard to survive.
i dont know where you got your numbers from oxygen is toxic at 187 feet not 223
So you also have come here after oceangate implosion 🥴
Nobody carea
I've seen like a million videos about oceans, submarines and fish since oceangate. CZcams is flooding me with these videos 🤣🤣🤣
Such a fun channel!!
Bet his neck is sore after bending it back 90 degrees just to look into the camera while his diving
Can’t wait anymore for quality content
Decompression sicknesses is also known as "the bends"
Yeah they said thay
No shit !
Thanks Captain Obvious
KRI Nanggala 402 is 850 meters 😭😭😭😭
So tldr: subnautica has either crazy new tech, or is just impossible ^^

Watching after hearing the final true allegations on the death of Naya Rivera. Rip beautiful, even tho I never was a fan this is truly sad. You had a family and all. Even if you didn’t, still didn’t deserve this. Rest up 🖤🖤🖤🖤
Staying underwater for 15 hours? No thanks
Was you a teacher at one point? You'd be a great one! Thanks for the info! Saturation divers is new to me.
Amazing that we can't even survive at 2000ft down when things live 5+ miles down
The biological limit for humans is 1000 meters.
The increasing pressure affects the cell membrane; if the pressure becomes too high, substances can no longer diffuse through the cell membrane (oxygen, sugar, fats, etc.).
Therefore, deep-sea organisms have thinner cell membranes.
If you bring such animals to the surface, they appear gelatinous / wobbly due to the much lower pressure on the surface.
Because the thinner cell membrane gives the cells less rigidity.

Can you do a video about diving depth when liquid breathing?
Liquid breathing ran into issues of removing corbon dioxide from the blood. It was also difficult to remove from the lungs after finishing diving and caused pneumonia in one of the test divers. And test animals drowned over the course of 8 hours. What I heard of it left it as more of an unfinished scifi concept. These commercial divers who use 1 percent of thier lungs don't sound like they're in desperate need of upgrading to the fluid breathing that risks being unable to get rid of corbon dioxide waste.
I can't remember the name of the vid that discussed liquid breathing but it sounded super risky.
whats the point of liquid breathing? there is a proper gas mixture for every depth.
The vid's that CZcams keeps recommending since Ocean Gate
I did free dive up to 45 metres. But now I have a permanent tinnitus at my left ear, althought I never had problems equalizing nor ever felt anything painful from pressure. That's what you get for trying to break your own limits
As a diver, the short and easy answer is: at the depth where the partial pressure of Oxygen makes it toxic. They try certain gas mixes to extend it but it doesn't help much, and certainly not for long.
You forgot to mention technical diving and helium escape valves
4:33 like for the piston legs lol
Stu smiles like devil ahahahaha 😂😂 Love you Stu ♥️😜

i really want to use Respiration III, and Turtle Helmet,
I searched for this due to Subnautica gameplay. You can sink and crush your submarine and Pronsuit, but depth pressure can't kill you or even cause Benz from resurfacing to fast. Subnautica must have magical default diving suits that instantly scrub nitrogen from your blood or something. Though your suit's O2 tank is so tiny that you'd inevitably dround if you're 17 minutes of travel distances deep underwater.
Given the choice between a large 30 minute O2 tank or a magic Benz preventing skintight diving suit, which would you rather have?
I've been 210' down on SCUBA on the shelf in Fla. off Dirtona Beach.
you think you can make another video about the peps that were down there for so long?
About as far as my sinuses will allow me. If plugged, not very far. So how do you keep those small sinus tubes that go up towards your ears clear?
Came here after knowing ‘ Titan implosion’
supose a person accidently drowns in maraina trench with oxygen bottle and mask can he get at botom and as heard there is presure .is there complete darkness .can he see or can he reach bottom in how may minutes or hours asuming it is 10 or 11 kilometers deep?
As a trained Freediver. I'd like to point out that Freediving is INCREADIBLY SAFE. But only if you get lessons and follow the rules...
Everything is safe, as long as you improve slowly and steadily and don't cross the line where it becomes unsafe ;)
Just can’t wait
Hope you enjoyed it!
Lot's of inaccuracies for those of us that have spent our lives underwater and want to be picky, but as a general presentation it's fair enough.
Is that why your head is shaped like a basketball?
The makers of this video are clearly not divers!! Still very interesting topic!!
proud to say my dad’s a saturation diver!! :)
Does the volume of water affects pressure in diving deep? for example a 5x5 pool which is 100m deep with 1k gallons of sea water vs 100m deep ocean with tons of seawater. Will it influence pressure? Why Or why not?
Pressure depends on depth and weight 1m^3 of liquid. Guess, ocean water is slightly different by composition to a swimming pool water (more salt e. t. c), as well the weight of 1 m^3 of water can be slightly different too.
What is length, width of pool doesn't matter.
Only how much water atop of you.
1. volume of waster doesn't affect diving deep - it's relatively proportional with depths, ~ 10m/32feets ~ +1 atmosphere, meaning at 20m/64feets there 3 atm, 40m -> 5 atm and etc.
2. volume affecting weight - 1 gallon ~ 133.53 oz/1.37kg , but pressure 10inch depth is same with slightly diff of how salty water is.
How they survive without eating for such a long period of decompression inside water
You can go without food for a while. I'm just wondering how the oxygen tank still has oxygen after 15 hours

Humans cannot survive at any depth (without aide) for much more than a few minutes (we cannot breath down there remember)
Correct me if I’m wrong but I thought you couldn’t get the bends from free diving because you’re not respiring? Was it from the insane depth?
For the most part, free divers are safe from DCS. You’re correct on the depth, doing repetitive deepdives in a single day or periodically in a couple of days will cause DCS but only due to deep depths
Just came here because of titan sub implosion 😨
I really like this guy's voice.
Thanks 😊
So do I
My cousin dive about 5k meters deep, but he never surfaced, so I guess that's how deep you can dive.
😟
lol you can atleast try to make it sound beleivable🤣
i bet you holding your breath while watching this 😂
I know what you mean 😆
RIP Ocean Gate Titan Submarine.
How do they get use the toilet while waiting days to decompress? If they were at 1000' working depth and used the toilet and opened a valve to (flush) it would be at 445 PSI!
I would love to take a selfie at the deepest part of the ocean one day. At least if I can’t get to mars (up), I might as well go down as a legend 😂
thanks stu
That is one record I don't want to beat
Lol just came from an old video of the world record being set at 315m. Reached in about 13 minutes, 12.5 hour dive!
Edit: from the title, I expected more info on the many free and assisted deep dive record holders.

How did they eat and stuff during decompression
Makes my deepest SCUBA dive of just over 50 mtrs look a tad feeble.
I have been to 22 mtrs on free dives!
All good with the decompression, but how do they eat and go to the bathroom? Are they in the water during the decompression or is the chamber filled with air???
Chamber is pressurized and pressure is slowly taken away until decompression is done.
watch the vid about the what will happen if you suddenly go up in surface pressure deep sea oil diver insdent
Not 100% sure but if you could acclimate to the pressures of whatever depth you're diving(including intake air pressure inside lungs...at the right O2 ratio) you should be able to survive and breath at any depth. Coming from the surface without adjusting or the proper things...yeah no
Those saturation diving depths are insane. The balls on those commercial divers. I can't think of a more insane job.
I dive to 30 meters regularly, I don't die and respawn ...
Yo the guy in the screem has its neck broken wjile diving what a boss
35 meters and my head is already felt like its gonna explode
what are you talking about?
As a commercial diver..I was taught in school..1280 Fsw is the deepest a human can be in the water with diving gear
damn. This channel deserves 10m not 0.5
Thanks! 🤞 One day
Romainian Unit 39 combat divers have a record for 501 m for chamber..
Thanks for the extra info 👍
So at that depth you could dive down and visit the Yamato Battleship and swim around it, and almost down to the USS Independence.
