Hi Chris, have you had some feedback about this information? Personally I've actually never had an instructor or fellow freediver suggest to hyperventilate, it's general knowledge for freedivers not to hyperventilate. I've watched this a few times because it's confused me a little. Huberman is the man! But I think this might be missing the mark
Number 1 rule of freediving: never dive alone. Number 2: Don't hyperventilate. Breathe normally (tidal breathing) There are simple protocols to mitigate the risks. Learn more about the sport by getting certified with Padi, Molchanovs, or SSI.
I'm a huge fan of Mr huberman, but I think he is wrong by generalizing how freedive es die, People Who really freedive as a discipline, know that this respiration tehnique hes talking about is "forbiden" in the sport. freediving is an increíble sport, you should digo more about it before panicking people out, if you do it with the respecyive protocolos the risk of dying is veeeeery small, I would dare to say that it is way safer than scubadiving for example. Scubadiving is easy, in freediving you have to train your mind and body. (I hope my grammar makes sense).
As a freediver this is only a small part of the picture. Firstly we never hyperventilate before a dive, ever. There is something called the Bohr effect which explains that by purging CO2 via hyperventilation, delivery of oxygen to muscles is worsened. Secondly, people lose consciousness under water due to lack of oxygen in the blood, nothing related to CO2. Yes we train CO2 tolerance but we pay great attention to oxygen levels or 'hypoxia' which is the dangerous thing.
Important point that should have been made explicit here... they die because of lack of oxygen. They just go to sleep. Lack of oxygen is a painless death.
Sure for freedivers. But it's not the case with rats, mice, or dogs when they're euthanized in a C02 chamber. I don't want to share the details. It's too gruesome and cruel.
Hyperventilating does help but its not safe to do so. Ive swam underwater hyperventilating and ive done it breathing normal. When you hyperventilate you feel more relaxed but you are more susceptible to blacking out as it’s happened to me before. When you take a few breaths without hyperventilating you can go longer and not get that dizzying blackness before blacking out
@@chaos616rev i was being cynical. This video is totally false. What he's describing as "what freedivers do" is something a complete reckless person who has no idea what freediving is would do (i dive 70m deep)
Freedivers never use hyperventilation breathwork because of the reason you just said. Blackout comes and without a dive buddy you're dead. That's why free divers NEVER use this method.
Been watching informative diving video analysis from the DIVE TALK channel. They mostly cover scuba but often will explain Free Diving out of necessity or because of context. Highly recommend checking out their channel. Thinking about literally taking a breath and then jumping into the ocean 30-60 feet down to swim around and come back up is so FUCKING insane to me😵💫😵💫.
usually you seem to be very prepared, what your talking about;but this time, this is only the half truth. it's correct, that hyperventilation is absolutely dangerous (and stupid) for life before diving ; the other side is, that it's forbidden to hyperventilate before going under water as every freediver knows. please add that to this clip.
Shallow water black out is not dying. It’s just passing out. Dying is what happens when you swim without a swim buddy and no one gets you to the surface.
Ugh What he’s describing is how some inexperienced or untrained individuals can suffer shallow water blackouts thru hyperventilating. Anyone who takes 60 seconds to learn about freediving knows that you don’t hyperventilate before diving as it’s dangerous.
That’s why they don’t train their hyperventilation technique anymore. You take normal breaths for two minutes with longer exhales to lower the heart rate, then one deep breath with a long, exhale, and then one final deep breath before going under. This way you still have that carbon dioxide reflex to breath when you still have 50% oxygen
He is talking about recreational swimmers who dive with zero knowledge on how to hold breath under water. Freedivers already know not to hyperventilate.
Huberman generally is very scientific but he'soff the mark here. Hyperventilation can cause blackouts because the CO2 levels are artificially low at the beginning of the breath hold, which mostly importantly means the normal trigger that makes one feel the urge to breathe isn't calibrated properly and people don't realize they're nearly out of O2 which is when you black out
This not really the whole truth. There has to be a depth factor for the "instant" blackout to occur. At depth a divers lungs are compressed and this helps deliver more oxygen to the blood. When they start to come back up the effect is reversed and the lungs actually suck oxygen back out of the blood. Suddenly the blood oxygen level becomes too low for consciousness and the diver blacks out. The physiology is a little more complicated than that (partial pressure of gases is involved) but that's mainly what happen.
If you are careful, it's really beautiful. I've had some nice dives in a wonderful turquoise water. The downside: I now have a water in my ear, hope it's going to come out soon .
Huberman has no idea what he's talking about here. In every Level 1 course, hyperventilation is literally taught as something you should NEVER do for this exact reason.
Cannot stand this free diving revolution. Everyone thinks there's some master free diver now buying these extra long obnoxious fins that they don't even know how to use for the smallest of spring. Posers everywhere! Oh and everyone is a mermaid now
freedivers don't do "cyclic hyperventilation". anyone who has done ANY training, or even just watched a "how to" video knows his lol. this video is fake news

We (Freediver) DO NOT Hyper Ventilate before a dive.... EVER. ALL Freediving training centers teach to NEVER Hyperventilate.
why
exactly! Dr Huberman this time you're full of bs
Yes. True, Prof HUBERMAN is confusing WIM HOF METHOD and Free diving training.
Please interview an actual freediver. Basic freediving course teaches not to hyperventilate before you dive.
100%
Number 1 rule of freediving: never dive alone.
Number 2: Don't hyperventilate. Breathe normally (tidal breathing)
There are simple protocols to mitigate the risks.

That took a turn real fast 😂😳
So essentially they’re training their bodies to not notice when they’re dying. Cool.
I’ll pass on that tho
Weak
Gasping underwater would lead to the same result tho
he has no idea what he is talking about
it a method that was accepted many years ago .. today freedivers have NOTHING at all from what he mentioned ..
Almost seems like a peaceful way to go...
If it is in a snap as Andrew describes than yes! Seems like a really peaceful way to die indeed.
I love free diving......the freedom to choose to dive with an oxygen tank.
Freedivers don't hyperventilate. That's dangerous for that exact reason he mentioned.

@@angelolee9044 I thought they inject drugs
This video is not clear about a very dangerous thing to do. Never hyperventilate before going underwater to hold your breath.
Andrew huberman’s demonstration of cyclic hyperventilated breathing is so much different than the way wim hof does it
Similar though, no? That's why there's a chance of passing out doing wim hof method
This is just plain wrong. Trained freedivers would never dive like this.
True. Most freedive deaths occur with untrained spear fishers. They go to deep and don't understand the risks.
Hyperventilating does help but its not safe to do so. Ive swam underwater hyperventilating and ive done it breathing normal.
When you hyperventilate you feel more relaxed but you are more susceptible to blacking out as it’s happened to me before.

I learned this even as a swimmer, it is called shallow water blackout. Very scary stuff.

Some wonderful analogy could be made about this to a lot of modern habits ;)

Dangerous sport to be respected
As a free diver this is not accurate

This is an old school, method. This is no longer a common practice and in fact is deemed very dangerous.
As a freediver this is complete BS
Well, it has a bit of truth to it in that hyperventilating before freediveing is dangerous. But the way he explains it misses a lot.
He is talking about recreational swimmers who dive with zero knowledge on how to hold breath under water.
Freedivers already know not to hyperventilate.

Why not do… anything else
today everybody knows that hyperventilation must be avoided in freediving.
sorry to say but he has no clue about freediving.

Arrest them so they are not free anymore
Well never mind im not go do free diveing
This is why Leon edwards is literally god almighty
It's not a sport. It's playing chicken with the Grim Reaper. Don't give it any respectability.
Most people can barely swim in uncomfortable water. I'll respect the folks who can die without pain.
@@onionfarmer3044 Aim for the top, buddy.

LIE!!! LYING!! LIAR!
HOW COME YOUR LYING???

bro has no clue what he's talking about!
first rule about freediving is to not hyperventilate
You are clueless about what freediving is.
This guy doesnt know what he is talking about. Interview a real freediver next time.
You have no idea what you're talking about
Okay yeah no 😂. Please interview @tedhearty
