Yes, not to be gratuitous but doing Wim Hof breathing before diving can and does lead to drowning.

It fixed my anxiety.I highly recommend

I did not need this reminder.

While that is true, and the full context only makes it worse, the important reminder is that a lot of people have died doing "Wim Hof" breathing before diving. It is not safe to hyperventilate before going into the water, because you are not saturating your blood with any more oxygen (normal breathing accomplishes that), but you are rejecting CO2. Your urgent need to breath is not triggered by low O2 but by high CO2.

So if you hyperventilate and then go under water, you will experience an urgent need to breath after you start to become hypoxic. This has killed people and will kill again. Don't let it be you.

"That guy has been cleaning his arse in our fountain again. Let's turn up the pressure to maximum."

If it had gone well, like it always did the previous times, then he would have shat out everything in his colon into the fountain.

Yes, really.

Ah yes the guy who psychologically tortured his own son so much the boy will have massive trauma(s) for rest of his life. Applies also to other people around him.

Really a person we should hold in high regard and listen to. Its not like that person invented cold or coping mechanisms with it.

So? What does that have to do with his breathing technique?
