If anyone is interested, I made an hour long mix of lots of waves and wind sounds, paying special attention to panning and levels to create a wide, enveloping, slow pulsing feeling that I use when doing heavy concentration work .
"We always have about two minutes to live, but breathing resets the clock."
Unaided, the record is about half that. Don’t try either at home. Freediving is extremely dangerous, even this version, where aid can always be at arm’s length.
Of course, when setting records it's done in the water (because of the diving reflex), which should never be attempted alone.
I recommend apps for "co2 tables" when practicing.
"Josh Waitzkin: The 30-second version is that I was doing some Wim Hof-inspired breath hold work. I made the mistake of doing it during lots of reps of underwater swims, 50-meter swims, at a pool in New York City. And on my eighth or 10th rep, I blacked out in a bliss state and I spent four minutes in the bottom of the pool after blacking out from oxygen deprivation. This old guy pulled me out and, which I’m eternally grateful for, and I basically drowned. All the doctors said after 45 to 60 seconds I should have been brain dead or dead, but it was four minutes on the bottom of the pool and that my training saved me. Also, you could say, put me there—but that’s a whole other conversation!"
This phenomenon is well-known, probably more so than Wim Hof. You’d think a ‘learning guru’ would learn about the potential risks of holding ones breath underwater while hyperventilating before attempting it!
Although the body requires oxygen for metabolism, low oxygen levels normally do not stimulate breathing. Rather, breathing is stimulated by higher carbon dioxide levels. As a result, breathing low-pressure air or a gas mixture with no oxygen at all (such as pure nitrogen) can lead to loss of consciousness without ever experiencing air hunger. This is especially perilous for high-altitude fighter pilots. It is also why flight attendants instruct passengers, in case of loss of cabin pressure, to apply the oxygen mask to themselves first before helping others; otherwise, one risks losing consciousness.
The respiratory centers try to maintain an arterial CO 2 pressure of 40 mm Hg. With intentional hyperventilation, the CO 2 content of arterial blood may be lowered to 10–20 mm Hg (the oxygen content of the blood is little affected), and the respiratory drive is diminished. This is why one can hold one's breath longer after hyperventilating than without hyperventilating. This carries the risk that unconsciousness may result before the need to breathe becomes overwhelming, which is why hyperventilation is particularly dangerous before free diving.
Obviously, when you combine such exercise with activities that require full attention, like swimming, frying a steak or driving a car you add a dimension of serious danger.
My favourite facts from the Wikipedia page are: it is originally called octopush and was played with an uncoated lead puck.
Now that I try to think of all the countries who have performed illegal medical experiments on prisoners... I didn't expect the list to be this long in my head... I thought it would be shorter.
It activates the "dive reflex" in humans which reduces psychological arousal. (Or something like that -- it is a non medicinal chill pill.)
I assumed it was a 'avoid drowning' response. Like if you fall into water, you don't want to stay asleep, you need to wake up really quickly!
At the end of the day we all react differently to different stimuli so try things out and do what works best for you.
If it's just your opinion then say that, don't try and make up some pseudo-scientific reasoning.
Originally you claimed a scientific response and that you knew the reason for it, now you're just commuting that to "well splashing water on my face wakes me up". Well, no shit Sherlock.
1) There is well established science that links the dive reflex to physiological changes in the human body.
2) Using the dive reflex as an anti-anxiety measure is well established in psychology.
3) Humans do respond differently to things and if they don't make you feel good, don't do them. There is nothing postmodern about arguing "some people enjoy a hot sauna and others find it miserable." My wife, for instance, will not do the dive reflex thing because it ruins her makeup. Individual variation is a thing.
4) I am not attempting to write airtight arguments to win a debate, but writing very loosely to share what I've learned with others.
5) If you're not sure about points 1-3, you are welcome to research them yourself instead of insisting I present them to you as formal arguments.
I would've also thought the "Or something like that" should allow for more a charitable response, and that's before we note that you're comparing two different starting states.
Most of the time it was a group of 2-5 people. When the group was only 2 or 3 people it often became similar to a smoke break where you could have a good discussion as you climbed up/down the full set of stairs.
The beauty of it was that almost everybody felt comfortable participating in it. If you have non-ambulatory coworkers who want to participate, perhaps a walk would be better. Management also liked it better than smoke breaks because they were always trying to lower health insurance costs so it was beneficial to encourage people to be more healthy.
Our building is 12 stories, so 1 complete up/down was pretty good and even the less healthy people could do it well after a few tries. If you're on a middle floor, go up/down/up (or the reverse) until you get back to your floor. If your building is taller/shorter then you may want to adjust the number of cycles. People who get tired can always exit at any floor and take the elevator back, but peer pressure usually pushes most people to exceed their comfort limit a little bit.
It was also a great team bonding experience because everyone wanted the whole team to make it and it was exciting when someone new joined or when you saw someone's physical ability improve. It's still not a smoke break, but it's the next best thing I've found... other than maybe grabbing a coffee/tea with someone.
Can also just take a walk. It's aimless, but still good for the mind.
It's because it's aimless that it's good for the mind. Or rather, good for you (because you are not the mind), because you get a break from your "crazy monkey mind".
"You" meaning anyone who does it, not literally you, of course.
Also see YouTube videos by Tibetan Buddhist monk Mingyur Rinpoche such as "Calming the Mind".
In that video he shares a great insight right near the start, which proves that everyone has awareness, even if they think they don't.

I seem to get a lot of good work done if I think it's rainy and stormy outside!
