Finally! Someone who makes sense and understands science (based on real data) and can communicate it - Thank you! As an old geezer recent retiree who's been away from snorkeling a long time and is going back to it, I see that I have not only a lot to learn & re-learn, there's a fair amount of stuff to unlearn before I get serious again and start to teach my grandaughter to snorkel. Now I know why I 'saw stars' a few times on 'the long trek up' when I was younger though I hyperventilated. You can't beat physiology & physics. Going to watch your series & read as much as I can first (and have another talk w/my doctor to make sure). A smart diver is usually a safe one - thank you for this public service in making us all smarter. Thanks for the eye-openers!
I'm interested, 'Now I know why I 'saw stars' a few times on 'the long trek up' when I was younger though I hyperventilated.' Was it blackout? Normally a black out has no warnings and you lose consciousness all of a sudden (I've never had one but this is what people say, and I've never heard of stars or warnings, that's why it's dangerous). If your feeling was being 'lightheaded' that's a different phenomenon caused by hyperventilation, basically too much oxygen can lead to an impaired flow of oxygen to the brain (there's an explanation for this, you can look it up if you're interested). I don't know if you've ever been to a doctor, but when they tell you take deep breaths and feel your chest with a stethoscope, they do warn you 'tell me if you feel dizzy or lightheaded'. Just to understand whether you fell and lost consciousness all of a sudden, or it was more like being very dizzy.
Hyperventilating doesn't increase oxygen saturation, at all. What it does is purge more CO2 out of your blood than is usual; and your body uses CO2 too tell you too inhale or exhale; so by rapidly decreasing your CO2 levels by hyperventilating, your body won't send out that urgent signal of "BREATHE NOW!" as soon as it otherwise would.
Yes, he mentions all of that very clearly too that's what the video was about. Just that I don't know why did he say that oxygen part in the beginning, maybe he intended to address the misconception.
Thank you for explaining something important very effectively. I want to add that a blackout doesn't only happen when you dive up, hyperventilating too much or taking 30 odd forceful deep breaths might make you not feel the urge to breath at all. So it could potentially be dangerous in any situation you try a prolonged breath hold after hyperventilating. Technically you do get more oxygen by hyperventilating, but it simply doesn't go where it needs to, it can impair the flow of oxygen to your brain (that's why some people might feel light headed after hyperventilation) and obviously as you said it starts lowering your CO2, so the more you hyperventilate, the higher the risk. That's why people work on CO2 tolerance. I don't go free diving, but I swim holding my breath 25m and 50m. Even though a blackout is very unlikely for the lengths I do and there's always someone around. I don't want to take any risks. Blackouts happen for multiple reasons, but hyperventilation gives you that false sense of comfort zone, that's why it should never be practiced, particularly underwater. If you read this and you're not convinced, try it, do it on a couch where you can't fall and can't hurt yourself and better if someone's with you, then hold your breath as much as you can and if you black out you'll safe. After that blackout, you realise you don't want that to happen under water without warning.
Hyperventilation could be your enemy! This is not a boxing sport, this is diving without equipment - freediving. Without enough C02 you'll stay a couple of seconds under the water, whose go na helps hemoglobin to transport a small oxygen that you have into your diaphragm! Good short explanation! MOST IMPORTANT IS that you must be relaxed and not stressed from anything before you dive ;) because every spend of energy will get a small portion from your amount of oxygen which is in your diaphragm close to your C02 ;) 1. No need for Hyperventilation because you will drop off your C02 nonstop and how fast is that you dob off more and more C02? Then your body will tell you, wow what are you doing? Slow down I can't take my necessary C02, which I need to my hemoglobin to transport oxygen to all my organs ;) Good talk ADRENO! Best Regards... 😎 ❤❤
To all divers: You don't need hyperventilation before you dive! 1. Relaksing your body on the surface. 2. Breathe quietly - a couple of minutes from your snorkel, until you feel that you are comfortable! 3. Go dive ;) Good luck
I just hyperventilated and held my breath I’m my dark room and I work up and my body was tingling and I think I hit my head, I was watching tv on my iPad while doing it to and it was only a few seconds, but when I woke up it also like I was crying uncontrollably but no tears were coming out and I wasn’t scared.
I play underwater rugby and the games are very high intensity which makes the dives max one min long. So could I use hyperventilation to my advantage if I just make dives under one minute? If someone wonders why the dives are so short, my heart rate is usually 170-190 while diving because you have to make full sprints with fins all the time.
why are some of the people in the vid fishing in a reflective suit and a bright red speargun? I know, that some fish might be interested and go check it out, but the ones, that are a little smarter are just gonna hide.
I can hold my breath above 4 minutes when I hyperventilate and basically feel like a predator in the sea. Fuck it, I will keep using hyperventilation technique.
yeah increased CO2 above 45mmHg will drop your pH to an acidotic level. Not fun. I've put a sats monitor on my finger and done breath holds. My SpO2 stayed at 98-100% even though I was in a world of pain. That's the CO2. That's the body responding to an acidotic environment. Many people do live with chronic hypercapnia (elevated CO2 levels). These people have COPD. There respiratory drive is controlled by hypoxia unlike those without COPD who rely on increased CO2 levels. This is why you don't give someone with COPD >3L/min O2. Yup, they'll stop breathing. Anyway, I digress. Yeah, I wish I could dive longer. lol.
Sorry folks,I do not agree on your Shark , diagonis of not being a big threat to humans, you chose all your words carefully, especially the Bull sharks, I read an article on a bull, it ate a car tire. Explain that lol.
I apologise for the annoying pauses. I do these clips off the cuff. I work full time and coach Freediving in the evenings. It doesn’t give me a chance to write my dialogue or practice. Im just hoping that with my time doing this coaching that I get my point across. 😁

such great info. and great explanation too. thankyou for taking the time.
Thanks bud. I couldn’t understand the difference between a breath up and hyperventilation. Now I know, no difference.
I always stretch before I dive and then do tidal breathing .Before I dive stick to 8 to 10 meters. Rule number 1 safety first.
I love that camo suit. Have a good day Mr. Wayne Judge.
thanks I am following with great interest. Greetings from Italy
Thanks Wayne. It's really helpful. Hopefully more to follow.
nice. thanks for sharing about hyperventilation.
Another informative video..Thank you

co2 actually helps with oxygen utilization. low levels of co2 will cause you to black out faster.

A reading of 100% o2 saturation is impossible in our atmosphere. If your ever at 100% it’s because of poisoning, like CO poisoning.
why are some of the people in the vid fishing in a reflective suit and a bright red speargun? I know, that some fish might be interested and go check it out, but the ones, that are a little smarter are just gonna hide.
If two breaths can get o2 to 100% then how is the blood in my feet get to 100% ? What is your reference?
Do a lot of spear fishers get eaten by sharks?
yes 100% of spear fishes get violently attacked by sharks and die
