I read that some free divers advised against hyperventilating. Instead they suggested to train to control urges to breathe despite rising CO2 in blood. This is much more difficult, but this way one keeps a solid indicator of dangerously low oxygen level.
- village-idiot 8y agoThat makes sense. I wonder if they do anything to add extra O2, or if that carries too high a risk of blackout due to low CO2 levels. I clearly am not a free diver. Either way, the all caps warning stands. And even experienced free divers black out on occasion, so be careful out there.
