I would contend that sleep is necessity for the processes of elimination.
Sleep is a metabolically minimal state. While we are awake metabolic activity is much higher, and our organs of elimination (kidneys, liver, bowels, skin, lungs) are under more load. We need to rest periodically to give these organs a chance to catch up.
We know now the brain even has a lymphatic channel, so for the brain sleep is, I suspect, a chance to enter an altered state of functioning to enable the lymphatic system a chance to do it's housecleaning.
This is the general 'disease model' that makes the most sense to me. That all disease has an elimination component to it, that the accumulation of the bodies own metabolic wastes contribute to the disease process, along with the 'bad' foods etc. Note I say component, because of course there's also a genetic component, as well as an environmental component, and the psycho-neuro-immunological component - that's the sciencey way of saying our thoughts affect our bodies.

> We should not forget that sleep-deprived animals die [...] mainly because of multiple visceral disorders in virtually all life supporting systems
It is really disturbing to read clinical facts like this and realize that we know them because someone dedicated, at a minimum, several months to slowly torturing a bunch of animals to death.

>several months to slowly torturing a bunch of animals to death.
How about years of slowly torturing a lot of humans to death then? (Unit 731, Nazis, etc.)

Then you'll realize that all our knowledge about what is harmful and poisonous probably comes from families of poor random dudes who eaten something new and died in agony.
How is that relevant? I mention a bad thing, you mention an even worse thing, case closed somehow?
How is that relevant? I will tell you.
Experiments on animals are not pretty, but they are the least harmful way of moving science forward.
The only thing we can do is to make sure no animal have to die/suffer without real necessity and be grateful for their sacrifices.

Where's the necessity in this experiment? How many human lives were saved by "gosh I wonder how long I can keep a rat awake before it literally dies"?
And why did you lump me in with Nazis, again?

Following your logic, Nazis/Unit 731 did nothing wrong, because after war a lot of human lives were saved by them/thanks to them. If you don't understand why i bring them up in the first place, go read about them. Specifically on what happened to them after war. It may change your view on modern science.

Uh, no, I was following your logic. You proposed the "real necessity" test. You can't turn it around and pretend that I said that first.

Sleep deprivation happens among soldiers, workers, people with various diseases. Learning how it works and why exactly do we suffer from it could yield a lot of important and practical insights for medicine.

Text after a blank line that is indented by two or more spaces is reproduced verbatim. (This is intended for code.)
Is this what you've done here? Because it makes the text annoying as buggery to read because of the horizontal scroll bar. The feature is intended to not line-break code.
Better to use asterisks to italicized.

This theory also opens the door to understanding all the other studies where, e.g., your intestine bacteria population determines your mood.
It also provides the causal connection between how your brain affects your body (e.g., via meditation) and vice versa (e.g., reflexology, acupuncture)

This is a really interesting article that I hadn't come across before. Thanks for posting!

That's a fascinating theory, I never realized the brain is never the primary cause of sleep-deprivation induced death. What sort of regulation do "visceral organs" like the immune system need that, if you don't sleep for long periods of time, they start to fail?
