If it only takes 4 minutes without oxygen to cause brain damage, how can they stay underwater for 4+ minuets and not hurt themselves.

I free drive! Something I take advantage of is what’s known as the Mammalian Dive Response, wherein when your face is immersed in water, it helps to elicit a calming affect. If you are very comfortable in the water you can basically go into a meditative like state before your dive, almost like you are sleeping. So you use much less oxygen than if you are in a normal waking state, out of the water. You can feel yourself relax and your heart rate slow down. Then you dive down, maintaining this tranquil state.

But make sure you know your limits and have a buddy with you who can help because it’s easy to black out under water, especially if you’re going for your personal best.
