Question

Can a human die if submerged in highly oxygenated liquid water and breathe normal?

In: Biology

Answer 1

As the others have said, no, water can’t hold enough oxygen.

There are liquids which can do that, though, but your lungs still aren’t equipped to cycle liquids without assistance simply due to how much more effort it takes to get the liquid in and out. You’d need the right liquid as well as a pump of some sort to “breathe normally.”
