![]() ![]() So those crucial organs, heart and brain, which are most oxygen deprivation sensitive they've got longer to have dibs at the oxygen you have got. But the majority is going to to the brain and we see this in any mammal.Ĭhris - Can I just clarify there Dan? So by pushing all the blood towards the central organs, heart, and brain, you're basically stopping the rest of the body having dibs into the oxygen that's in there. So what happens is that oxygenated blood rather than going into the limbs, is actually going primarily to the brain, still a lot going to the heart. If you hold your breath, your heart rate slows down, and part of that is you start to get a vasoconstriction in the periphery. We all have what's called mammalian dive reflex, and it's designed to prevent us from dying very very quickly in water. ![]() Actually, there’s a couple of real simple parts to this. And it was a couple years ago, 2016, it was eleven minutes thirty-three. It's actually, the second challenge is having somebody lying just you know, in a swimming pool and holding their breath. But if we go with what's recognised in breath holding circles, and it's actually part of the free diving community, so if you look at the free diving challenges, it's not just about how deep somebody can dive. And then held their breath for twenty four minutes and three seconds. So what they did was they breathed 100 percent pure oxygen and it's still extraordinary. So the current world record for holding breath is eleven minutes thirty-three seconds.ĭan - Now you will see that there are also reports out there of somebody being able to hold it for twenty four minutes and three seconds, so the caveat on that one is they were allowed to breathe 100 percent pure oxygen before. Exercise expert Dan Gordon took on this question from Phil.ĭan - We've got to be slightly careful, because there's a lot of information out there which is slightly misleading. ![]()
