I've actually tried these types of practices, and they make me feel like I've used a recreational inhalant. Without the paper I'd have assumed giving yourself mild hypoxia just gave you euphoria and dizziness, and other positive effects were confirmation bias.

Interesting! I guess you need a good teacher, or you could just be "different to the bell curve". I mean theoretically every little thing is going to have potentially different effects for everybody. But I want to ask...so even doing something like box breathing (4 counts inhale - 4 hold full - 4 exhale - 4 hold empty - ... repeat), give you feeling of mild hypoxia / euphoria / dizziness / like an inhalant?

Also, this will probably sound judgy so I'm sorry but I'm really curious: do you normally have trouble walking up stairs, get out of breath easily, or feel faint when changing body positions?
