Eli5 why do we CONSTANTLY need oxygen?

500 views

Surely we can switch off for a little while like a half hour and be fine why does everything just immediately fail if we don’t get oxygen? It’s such a design flaw. What is it actually doing to me that is so necessary I need it constantly?

The natural processes going on in living cells require energy, accessing that energy uses oxygen and converts it into carbon dioxide, no oxygen and the individual cells die, if enough cells die the body dies.
