> Lie down, do a push up, then jump up to your feet, upright, arms raised (Burpee). Repeat in rapid succession twelve times, then immediately shut your mouth and close your nose with your hand. Hold it. Close your eyes and imagine you are under water and don‘t know how long it will take till you can resurface.
you forget, ‘put a blindfold on and tie your leg to a doberman’s leash then fall down 3-6 flights of stairs’
pretty similar forces and sensory at play, or at least a similar thrashing to big Teahupo’o over a sharp reef.
A safe way to get a similar disorienting experience is hold your breath under water while in a tight ball and have someone spin you on every direction and reverse it until you can't stand it and then wait another ten seconds.
I recall being swallowed by a wave and while under for only a short period i thought it was annoying not knowing when I'd return to the surface.
