How long it takes to blackout from holding your breath if you don’t move that much? Will it take longer for a trained individual? It seems like there isn’t much known about it or what have an effect on it, like height, weight, age, gender, etc. I know the breathing reflex will kick in before but if it didn’t, how long would it take? I know men have larger lung capacities but women consume less oxygen. Answers are all over the place. Are there any answers for it?
