I’m being cautious, but, the cans of pure oxygen say to do “1-2 seconds each time,” but I’m like, “how many times can you do? And how long should you wait between times!?

Hey cool

I don't use oxygen cuz I don't get headaches myself; a friend who used to had cluster headaches told me about it, they have read it on a internet mutual-help-group about that syndrome

Oxygen can be poisonous at 1.4 atm partial pressure so make sure to not inhale 100% oxygen while at 4 meters deep in water. That is ridiculous I know, but if the can and the medics says to not over do it, they surely know better.

That same friend who told me about the oxygen used to get terrible headaches when the atmosferic pressure was low and they got relief by free diving, chilling at the bottom of the swimming pool was their cure. They never tried the oxygen cuz turns out they had a hormonal imbalance and fixing that apparently also fixed their mean headaches.
