What kind of breathwork did you do?

Circular but without outside supervision. Not sure if I did something wrong or if I need some customized practice. I am often running out of breath/out of sync breathwise when singing, often getting lightheaded effect which I do not like at all.

I've had this described to me as basically the combination of neuro+psychological effects of hyperventilation (respiratory alkalosis) in a peaceful/positive environment (as opposed to anxiety-attack-driven or etc.), plus the meditative effects of deep breathing, plus the meditative/brain-entrainment effects of rhythmic movement of a major central/core muscle (diaphragm). Together, those often cause euphoria, altered…

I have a degree in building science, so maybe I can chime in. Note of caution: you will find yourself breathing heavily after reading this. It's normal. We do a terrible job at ventilating our indoor spaces. As a cave-dwelling species our brains are quite comfortable with tuning out bad smells and tolerating stale air -- but the effect of it on our mode and well-being is almost immediate. You don't notice the effect,…

Destin from Smarter Every Day (YouTube) has a wonderful video demonstrating this effect [0]. I’d recommend watching the whole thing, but you can see how much of an effect it has starting around the 6:00 mark.

i am a (former) neuroscientist and breathwork facilitator (mostly conscious connected breath) — AMA.

the effect of decreased co2 concentration on vasoconstrictions (and also alkalosis-induced tetany, ie your muscles cramping, which happens a lot during breathwork) are well known [1], but i've never seen them quantified in such a clear way. It's cool to see mainstream science give it a closer look!

I'm a philosopher, not a medical professional. But I can tell you that philosophy and deep breathing are inextricably linked. Breathing deeply in of itself is a philosophical exercise, one that centers and grounds oneself in the here and now of the universe that surrounds you, and the universe that lies deep within you. It's a cosmic balance between the metaphysical and the empirical. As a philosopher, one must be able to breathe deeply, so one can breathe in, hold, and spew out the deepest and most esoteric pearls of knowledge unto the masses.

I got into doing this Wim Hof breathing exercise a few years ago and it was definitely intense. Unsure if this is related but sounds similar. https://youtu.be/0BNejY1e9ik?si=kgBBUhqMe9HWaKCG

Intense but did you get any lasting change from it? Are you still practicing? I did some breathwork and disturbed something with my natural breathing pattern. For about two weeks I had insomnias and was constantly lightheaded. Im reluctant to try again..

I did it when I was really working on myself emotionally and it was for a limited time. It could be a bit scary because of the extreme feeling of lightheadedness. But it did cause a pseudo euphoric feeling too. Afterward I felt invigorated.

But yeah it had a layer of unpleasantness that made me not continue long term.

I've experimented with holotropic breathwork, and was quite amazed at the experience. Unfortunately, as much as I've tried to re-create the experience while not lead, I find my mind just doesn't want to go beyond about 5-10 minutes of breathing, vs the 30 minutes I did in breathwork sessions. Having said that, I think the design of this study could be much improved. It shouldn't be too difficult to create a double bl…

it's an incredibly hard workout, depending on the style you're actually using a lot of muscles that you don't typically exercise, so your body wants to naturally give up after a while. it took me probably 6-8 sessions until I could reliably do one myself.

I don't mean to be too critical, but why is breathwork/meditation so popular in Atheist circles? When I would presume rationality is the goal, and this seems like it would alter it in a negative way. (depriving your brain of oxygen, presumably decreases its ability to think rationally, or at least run at full capacity) I get that someone like Sam Harris, makes bank promoting his meditation app. But his atheist audien…

I used Harris's app, and was a bit surprised to hear him use language that he'd savage anyone else for.

I get the problem there; you're trying to teach what something feels like, and there just aren't words.

It's not surprising that you can alter the brain by various exercises, or that those exercises are counterintuitive. The brain is complicated and our tools for manipulating it are baroque. Still, it was a little weird to hear Harris give in without apparently reconsidering other forms of mental exercise from that standpoint.

Atheism isn't specifically "a goal of rationality" it's just not believing in a deity (usually because of a rejection of "trust me bro, now pay your tithing" style pitches). I expect for most people the choice to believe or not believe stories with no evidence is orthogonal to the choice of an altered mind.

Earlier quoted context omitted.

If you presume rationality is the goal, then the rational mind should point to decades of research and anecdotal evidence that shows the positive effeccts of meditation and breathwork on mental well-being. Why are you assuming depriving your brain of oxygen for a short period of time is decreases the ability to think rationally? That could be a short term effect, but a long term adaptive effect could be the brain thi…

Well, if one's thoughts can be altered depending on the amount of oxygen the brain receives. How can you possibly be sure about your own rationality. Couldn't you rationally start to question anything you've come to a conclusion about before, as just a byproduct of your brain's oxygen levels at that time.

The best part about true things is they are still true whether you believe and understand them or not. Seeking truth isn't limited by your ability to understand everything.

I wonder if there's a vagal nerve effect from the increased chest pressure while holding your breath in. I do the 'double sharp inhale' method for the anxiolytic effect occasionally - not really something you can do at the office however.

I hate getting startled, even when I realize right away that there is nothing to worry about. But the physiological effects, once set in motion, carry on. My heart seems to skip a beat and then rev up to a high rate and it's uncomfortable, taking some time to come back down to normal. Some years ago, I discovered a technique to suppress the effect of being startled. I just breathe in sharply, using mostly my diagphra…

That sounds like an excellent theory.
