Interesting, I found that hyperventilating is actually pretty much guaranteed to cause a fainting for me. The method is to sit down as low as feasible, maybe even lie down, hyperventilate for about a minute, and then rapidly stand up. I used to do this to faint on command until I hurt myself falling on a concrete patio. Now I know this effect has a name and a possible mitigation, yay!
- CoastalCoder 5y agoVery tangential, but your comment reminded me of this... I have this weird trick where I can put the back of my tongue against the roof of my mouth, and exhale I'm a certain way that causes a whistling sound, I think where my sinuses reach my throat. That often makes me light-headed very shortly after for some reason.
- MetallicCloud 5y agoSame thing for me. I used to do it with friends when I was a teenager. Until they got the idea I was faking and let me hit the deck, expecting me to catch myself.
