Actually it's not, it's lack of oxygen.

There is plenty of oxygen in water

Which is why a fish doesn't drown when you take it out of water. It dies of too much oxygen. Water at 15 degrees C contains about 10ppm dissolved oxygen, or about 0.001% Air is about 18% oxygen.

A fish can live outside water for far longer than we can live under it because oxygen poisoning is a slow process and you suffer few side effects from short exposures (why fish can be returned to the water 10 minutes after being caught for some fish). As it recovers it's not waiting for the oxygen level in it's blood to to go up, it's waiting for it to go down!

As a diver I can say confidently that for all practical terms for human survival there f***ing well isn't!

What may class as interesting is that in many cases of drowning when water hits the back of the throat it causes the larynx to go into spasm and close off the airway, meaning you drown without water getting into the lungs.

Is there not also supposed to be a moment of euthoria just before you die, at the point where you're airways open and you try to breathe... then fail horrifically.
