I cant even sit still breathing on land for 5 minutes 😂
@BillyLongshot Says:
Oh man, I had to go to the loo but was afraid to pause the video, in case the guy might drown
@peterolbrisch8970 Says:
I can hold my breath for a long long time!😂😂😂😂
@adamb89 Says:
Always thought it'd be funny to just leave one of these guys in the tube. Eventually they'll realize you're not letting them out, and that's when the panic starts, and that's what you wanna film. The moments between when he realizes he's _going_ to die, and when he _actually_ dies. After the first time I saw it I couldn't get enough of it.
@samsungnotezece Says:
Thank you. This saved my life.
You can pass out before you get the urge to breathe. That's dangerous.

Yayayaha
@obliv6926 Says:
16:24 - Crazy... i've just experienced this. I came after videos about holding your breath safely. I had just finished holding my breath for 2 minutes. Fighting the urge to breath in the last 30 seconds. Quite fiercely in the last 10 seconds just so i could reach a round 2 minutes. After releasing and starting to breath again, the timer was still running. I didn't see the next 5 seconds go by. It's like it went by in a bling of an eye. The next 5 seconds went by in two blinks and so forth.

The science behind hypoxic blackout
Before going underwater, a swimmer sometimes purposely hyperventilates. A less common cause of hypoxic blackout can be the result of an underlying heart abnormality, often unrecognised. Blackout occurs because the normal, protective 'breakpoint' – or the irresistible urge to breathe - has not been reached before consciousness is lost.
There are two chemical sensors in the body which detect levels of oxygen and carbon dioxide (CO2) in the blood. These protect us from a lack of oxygen. The CO2 sensor is the most sensitive; and when CO2 rises to a critical point, the breakpoint is reached first. Under normal circumstances, when a swimmer is trying to stay underwater for as long as possible, the 'breakpoint' forces the swimmer to the surface to take a breath. If a person is submerged and the 'breakpoint' is reached while the mouth and nose are still underwater, the irresistible urge to take a breath still occurs, and water is inhaled into the lungs.

18:17 man his laugh. I heard it before. Not just earlier in the video. This is a laugh of dangerous knowledge.

If your drowning just drink the water 🤔
@RobCampbell-y3u Says:
This man risked his own life for a YouTube video, now if that's not pure commitment, I don't know _what_ is

3:05 the chilli in my vinegar 😂
@gottasaybs Says:
I can significantly hold breathe longer when I am in cold water ... Idk why
@HyungnamGu Says:
When cold water touches the face, specifically the forehead, eyes, and nose, the trigeminal nerve (Cranial Nerve V) detects the drop in temperature and acts as the primary sensory trigger for a vital physiological response known as the mammalian dive reflex or trigeminovagal reflex.
The trigeminal nerve carries this temperature information to the brainstem (specifically the medulla), where it initiates a series of automatic, parasympathetically mediated responses to conserve oxygen and reduce stress.
Key Responses Triggered by the Trigeminal Nerve:
Bradycardia (Slowed Heart Rate): The vagus nerve (Cranial Nerve X) is activated, immediately reducing the heart rate to conserve oxygen.
Peripheral Vasoconstriction: Blood vessels in the limbs and skin constrict, reducing blood flow to non-essential areas and prioritizing oxygen supply to the heart and brain.
Breath-Holding (Apnea): The reflex promotes immediate voluntary or involuntary apnea, preventing water from entering the lungs.
Blood Pressure Regulation: While bradycardia occurs, the vasoconstriction causes an increase in mean arterial blood pressure, optimizing blood flow to the brain.
Panic Relief: Cold stimulation of the trigeminal nerve can break the cycle of panic by activating the parasympathetic system, reducing sympathetic "fight or flight" arousal.

what a breathtaking video!!

Can we talk about that swimsuit you're wearing in the pool?
@Fantomas24ARM Says:
I did almost 2 minutes. It was scary because I felt like I could hold more but I was too scared to continue.

Please do Research first. I heard air packing can be dangerous
@ContextWouldntHelpMuch Says:
I like to hold my breath whenever I watch a movie where their is an underwater scene to see if I would survive. When I was watching Finding Nemo I almost died. I have always loved this joke, but for Brandon Birchak it could be a reality.
@Bee-qm3mr Says:
he would be a great mermaid
@053_ganeshgorobabhutekar2 Says:
well i can hold upto 1:43 second
@SeltzerCole1 Says:
Only sheep watch this.

The dude in the tank is just dead
@johnpothala3449 Says:
wow this is the life ...I get to watch a world class athlete live in action with the timer on, in a running documentary .most unique video ever..the only ones that comes close are those single shot movies that win oscars.
@Barwaaqogardens Says:
Me at 0:30: 'Okay, I can do this.'
Me at 0:45: aggressively negotiating with my CO₂ receptors like they're a hostage situation.
Brandon at 17:00: still chilling, probably judging my entire existence
@otto4735 Says:
in the begining i thought it was a tiny guy in a tink tank 🤣
@dylanpearce1366 Says:
I brothe manually for the whole video
@drpadmajahulamani4998 Says:
It's a really good video to learn breath holding .... Grt motivation....if Derek can hold 2.30 in just half an hours training.... We can also try...Thanks for this video

You’re pushing my personal boundaries
@OfficialGrifun12 Says:
just to warn yall (as veritasium said)... do NOT try this at home or you could drown
@haros2868 Says:
Either they cut some scenes to condense the footage, or they said to the poor guy "hold for 2 more minutes hang there" 😂. No way its a coincidence
@DevWithDavidJSX Says:
WHo's here in 2026?
@RobHartman-n1p Says:
yea but did you cheat and oxygenate your blood beforehand?
@HighRaphinha Says:
9:32 he took a breath
@hdfxdcsuperglide3016 Says:
One can visibly see he is sucking air from the tubes.
@hdfxdcsuperglide3016 Says:
He is wearing too many cables in my opinion. If he did not wear a shirt and had no cables I would believe this. I call BS....
@Scruenut Says:
Would love to see more like this. Maybe a part two.
@Nanostarical Says:
This is no where near as my nephew been underwater for the past 7 years, we are still trying to where he went.

i kept holding my breath while watching this on accident
