the main reason is not sleep deprivation nor over sleeping.. . its instead oxygen deprivation or organ failure
no one dies because they needed 48hours sleep and simply unable to wake up.
they die because an organ shuts down(heart) or they are deprived of oxygen
you do realise that people can live for weeks without food. so your notion of dying due to lack of food within 48 hours is not a good assumption to make
thinking that people die due to malnutrition within 48 hours is silly
people dont die simply due to oversleeping
thinking that people die due to over sleeping within 48 hours is silly
this is one giant BS. I said you are BS-ing... organs failure??? A low of life support unit resource lead to a organ failure during the sleep? which one come first, how could that perfectly healthy organs could go failure during a sleep?? soldier are generally weak ass who could easily get organs failure?? make me think twice!
Even when a person does not sleep for 3 days, a sleep of 8 hours he can already recover from that exhaustion. But people sleeping up to 48 hours is not normal and they could forget to wake up after that.
There had been reports of death because they were choked by their tongue while asleep but not to lack of resources. AFAIK our metabolism slows down also while as sleep to which the only busy organ is our ears.
