Dope Tech Episode 2

<<@M.khaledKhoshaifatee says : 12:30 Brandon is suffocating and your making an ad>> <<@Ra-Ksg says : When I play a really intense game, I basically stop breathing for about half a minute longer than when I manually did it. Why is that???🤔🤔🤔>> <<@Chung14-e8z says : Me watching this video because i like breathplay:>> <<@pianoprimo1715 says : This reminds me of the story "a hunger artist " by Steven Kafka. Otherwise, I think it'd be useful to know the technique if you scuba and have careless people fill your o2 canister/tanks.>> <<@OSKARBASSO says : bro! 18 minutes>> <<@PearsonMoreno says : I’ve held my breath for a minute and I thought, dang I’m good, meanwhile this guy is holding his breath for 18.>> <<@santiagodemarco547 says : Once time I endured without breathing 90 seconds at most.>> <<@I-Swear-to-Science-raised-90s says : I breathed Out all my air, after 45 seconds, I still had time left in me... 😮>> <<@luna_baddiepgg says : Bro I would be rip 💀🥀>> <<@leadslinger says : The record now is 29mins 3 seconds 😮>> <<@ethanclark3035 says : Their website is not very user-friendly, in my opinion>> <<@thetruthexperiment says : I’ll give you the benefit of the doubt here but the Wim Hoff method works. Holding your break for five minutes is pretty easy doing it his way. I’m seeing so much bad science here because it doesn’t line up with other science and personal experience>> <<@JDPyrotechnics says : As someone who manually breathes, thanks I needed to think more about breathing>> <<@Behrouziyeh says : CGP GRAY TSHIRT!!!>> <<@jwmmitch says : So the cool water gives you an advantage? Interesting How long can Brandon hold his breath out?>> <<@Supply8644 says : 1:33 he beat my record>> <<@MonekyMike says : Im going to have a breath hold contest with my friend. Whoever dies first looses>> <<@H.Doc11 says : The dolphin hold their breath nine minute, that guy can kill a dolphin 🐬 under water>> <<@Brasman98 says : I get why you have an ad in the video and always make sure to watch it completely and while my browser tab is in focus and the video in full screen, in order to make sure watching it does help the channel. That being said, doing an ad read while someone is trying to hold his breath for the duration of the video is kind of a dick move...>> <<@dr.mondschein6460 says : Reality tv>> <<@randomskibiditest23 says : its so crazy how we humans can manipulate our brain into learning almost anything i mean there are animals made to live underwater and some cant hold their breath as long as a well trained human a species which lives on land>> <<@JeffreyEuler says : 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.>> <<@0B0T_the_periwinkle_warrior says : 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.>> <<@DewdMcPerson-k7n says : I don’t believe this, he’s moving too much>> <<@HyungnamGu says : 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.>> <<@mikesantos011 says : that thumbnail is wild lol>> <<@KI11TY-t5u says : 10:17 I broke I the 1.13 mark….>> <<@manofmanytalentsfawazakkar4068 says : 18:17 man his laugh. I heard it before. Not just earlier in the video. This is a laugh of dangerous knowledge.>> <<@Slinkyreal says : 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>> <<@æethel says : 3:05 the chilli in my vinegar 😂>> <<@æethel 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.>> <<@ariyach6562 says : what a breathtaking video!!>> <<@duncanbeggs4088 says : 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.>> <<@Elvinhasmoney says : 11:14 he is at 11:11🎉🎉>> <<@Elvinhasmoney says : 5:03 bro hit -5:00- A.K.A 5 min 🎉🎉🎉>> <<@henrybrammall says : I Don’t like that 13:42>> <<@Jannis-u7m says : 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.>> <<@EdwardThompson-yu4um says : The dude in the tank is just dead>>
