A potentially great method that I haven’t seen discussed

[BlissfulEnigma]

So I'm sure most of you know how SWB works, it basically takes advantage of rapid breathing (hyperventilating) so that you get rid of as much CO2 as possible, and then you hold your breath underwater to deplete your oxygen until you pass out (without ever getting a sense of "drowning" because that is caused by high CO2 and you've reduced it drastically by hyperventilating).

However, this seems to be quite a risk, because if you don't pass out before the CO2 builds up high enough then you might still drown and not even be able to save yourself because your oxygen is too low to think (but not quite enough to pass out).

Now, I'm not saying that would happen if you did everything right, it's totally possible to SWB without pain. But it's also quite disturbing for those that discover you in the morning (or whatever time).

But then I realized that you can do this all on land! All you have to do is hyperventilate as much as possible (I recommend wim hof lying down), breathe out as much air as you can, and tape your mouth and nose shut immediately afterwards. At this point, you would hold your breath as long as possible until you inevitably pass out and die a peaceful death (with no drowning). Now, in practice, I don't know how well this would work. I imagine you should tape your nose shut first so that you only have to tape your mouth later. And obviously practice is important, but if anyone has any comments or if this has been attempted please comment.

This is really interesting, how do you make sure you stay down under though? Or do you essentially guaranteed die after you have a lungful of water I've wondered about that.

The land one makes me worry about accidentally ripping off the tape when you're semi-conscious.

Even in water, this is a very unreliable method, with many reports of trying and seemingly no cases of success. It happens accidentally due to many different variables, as @hell toupee explains here:

You can't just hyperventilate, pass out, and drown. That's not what SWB is.

SWB is when a diver hyperventilates, remains conscious, and then proceeds to hold their breath so long that they pass out. But the reason they pass out has to do with many physiological variables, one of them being the compression of the lung at depth (allowing the free diver to hold their breath even longer), and then the decompression of the lungs as they surface. They then pass out because they have been holding their breath for so long, part of which hyperventilation allows them to do.

Everyone who I've seen hyperventilate, including myself, passes out for less than 5 seconds. If you were to hyperventilate then attempt to pass out and drown, you would wake up immediately and experience everything that goes with drowning - which, according to a few anecdotal reports on here of people who survived accidental drownings in their youth, is very painful.

I don't know why they closed the mega thread on this method, but I suspect it is because it is not viable.
