The average person runs out of breath after a little more than a minute. What did you find most fascinating about the science behind free diving?

[@aqwert147]

That im not avarage 🤣

[@timallen643]

In my younger days I used to be able to hold my breath for quite a while while swimming. I could Traverse a full length pool three times on a good day.

[@stoicfreediver]

That you didn’t do your research before posting this useless video - delete it and try again.

[@TheTurtleOfGods]

National geographic appears to have prior knowledge of the sport equal to that of the "average person"

Click bait - poor quality content. Deleting this is a great idea. Do some research with actual freedivers next time.

He takes data from super deep divers and uses that to conclude no one should do this, awful video.

He doesn’t have to dive to read a script and explain what could happen!

[@darling_4467]

Imagine diving and and all of sudden you hear something says: *Detecting multiple leviathan class lifeforms in the region. Are you certain whatever you are doing is worth it?*

[@marklaurencefirmeza2473]

Subnautica

[@williambautista8929]

😂😂

[@jeythegrey]

Sadly, not much is explained here... So let me help: when you dive, the pressure around you (from the water) compresses your lungs as they are filled with air. This compression leads to compression of the gases as well, which makes it easier for the lungs to absorb the remaining oxygen in it. The pressure also compresses the gases that are usually in solution (like nitrogen) in your blood. When you now swim back to the surface too fast, because you feel the need to breathe, your lung rapidly decompresses as the gases expand, making it much harder to extract oxygen. You suddenly have way too little oxygen in your system from the rapid pressure drop, making you fall unconscious (brain and muscle tissue are deprived of oxygen). On top of that, gases that were compressed in your blood, also expand quickly, forming bubbles in your blood that can block blood vessels and lead to infarcts.

[@janniebautista5483]

thanks for ruining my dream of learning how to free dive 😔

[@socalspear3894]

Most of the fun for recreational free diving / spearfishing happens in 0-60 feet. No need to try for these extreme 300+ depths. Still dangerous though and I highly recommend taking a class if you’re a beginner. You’ll learn invaluable safety information.

[@luwkseam]

@@janniebautista5483 Don't get scared by this bs. Take a freediving course or at least read book by any of great freedivers, like Umberto Pelizzari, William Trubridge, ... I am a middle-aged guy and I am training for 5 years now. If you love water you are going to love this :)

[@luwkseam]

@JeyTheGrey I am afraid you are not entirely correct here. 1st of all, the rapid desaturation leading to a decompression sickness which you mention at the end practically never occurs in freedivers (except in extreme record-beating performances) since they don't spend enough time at the depth to saturate and they never breathe air at the depth (contrary to scuba divers). 2nd the rapid pressure drop in the ventilation system does not automatically lead to an oxygen starvation. Since the greatest pressure difference occurs closest to the surface, freediviers in 99,99% of cases are able to breathe-in fresh air before oxygen level in blood drops enough to cause a blackout.

[@tingwei1016]

It’s called shallow water blackout, when your PO2 levels change too fast because you are ascending too fast. To avoid it, ascend within the last 10 meters or so with minimal finning, rather use your positive buoyancy to pull you up naturally to the surface and make sure to do recovery breaths correctly.

[@hubertmarchand2689]

Decompression sickness does not happen in freediving unless you are doing multiple deep dives one after the other. Not enought time to accumulate nitrogen

[@jacksonkoeppel2533]

how deep do you have to go for it to happen?

[@girabbit]

@@jacksonkoeppel2533 It's not a specific threshold, more like: Time under water X Depth reached = probability of DCS. But as others have said it's exceedingly rare.

[@jacksonkoeppel2533]

@@girabbit what about free diving

[@girabbit]

@@jacksonkoeppel2533 Yep my comment is referring to freediving. I believe that when competitive freedivers are going to 80-120 metres, they will only do one or two dives per day just in case.

[@jacksonkoeppel2533]

@@girabbit ok thanks

[@pattravels]

Superficial and misleading info about freediving. Really a shame.

[@lucashandley9856]

If the intention was to give information to the public in order to educate and make it safer for people; you missed explaining the part which is the most dangerous.... hyperventilating. Taking big breaths before you hold your breath is literally the most dangerous thing people can do for freediving. No “breath up,” no yogic breathing, no WimHof... that’ll kill you if you mix it with freediving. Tell people not to do this and you’ve done your job. There, now people are safer.

[@umarkhan-ru9dz]

dear can you plz guide us

[@michenesi]

Freediving is a real discovery. You can feel so much while underwater. Is it dangerous? Yes it is. That is why you have to take a serious course and never do it alone. To say that it is too dangerous and not fascinating: that is stupid!

[@DonutMaple]

Wow... I was expecting more when I saw the Natgeo logo

[@nexofilipe]

I remember when discovery channel resonated with knowledge rather than clickbait and silly scripted text.

[@Ali94749]

This video needed to be fact checked. The guy lists a bunch of dangers that are only present for scuba divers 😂

[@ElNietoPR]

This video feels like an early 2000’s discovery channel segment

[@veritas88n4]

[@MargoIndigo]

“flippers” us divers: *imma take my gear and head out*

[@tikilo3303]

I learned absolutely nothing

[@zachwalker8985]

I don’t like the approach. The title is definitely click bate but they are driving fear. The shark chasing the diver after his turn in the cartoon is a clear representation of this. Freediving must be performed with safety, knowledge and a buddy but this seems like more of a smear campaign then science video. Plus who names a series Science of stupid. What a negative name for something meant to be educational.

[@Srfingfreak]

Imagine if the great National Geographic, a 132 year old organization, tried to be Tik Tok. Sad.

[@juniorsmith1364]

I doo spearfishing for a living and every freediver know the depths they can dive to .your body tells you when to stop .or when to tho back up ⬆️.

[@energizedviper42]

Lol the way the dude swam into the wall

[@garrettcirrincione3208]

NatGeo? This had the information quality of a VOX video smh

[@wildeast66]

Neither neitrogen narcosis nor decompression sickness are a problem of free divers. At least not if not done extremely. For both you have to spend a significant amount of time in the depths, which can not be reached easily by apnoe diving.

[@adtfor]

so true

[@10918l.h.g]

Free diving seems very fun, but I couldn't try it because I didn't have a chance. I admire the fact that the free diver in the video broke his record. After watching the video, I wanted to give it a try. It was surprising to see the free diver in the video diving across the size of a soccer field while holding his breath. When a beginner diver dives, he learns that oxygen is supplied to his head and delivered to his vital organs.

[@slgarrett]

Definitely among the worst bits of information I’ve found on freediving.

[@fakecupcake123]

Almost nothing was explained🙄

[@Bigfoot_With_Internet_Access]

cgarciahfcu It’s called “Aquarium” by Camille Saint-Saens. You’re right about Disney, they used a variation of this theme in the soundtrack to Beauty and the Beast (remake).

Its only dangerous if you are an irrational idiot who dives without theory, training or safety. Its a safe and beautiful sport that offers a lot of benefits for physical and mental health.

No you cannot get decompression sickness from freediving only from scuba diving

[@nikosstournaras4271]

Decompression sickness is almost impossible in free diving. The mammalian reflex has to do with blood circulation and heart rate slowdown not with finning. The video is full of false information and childish humour by someone, apparently, completely ignorant about the subject.
