There definitely was never a life form which exclusively slept - all the critical parts of life require being awake. Life that didn't sleep, however, is possible.

Plants?

Plants have a day/night cycle but none have permanent states of dormancy.

Sleep is super important. I’ve seen too many workaholic types that barely sleep. So many of these folks end up with serious issues later in life.

One best things about getting laid off from work is that one get to sleep as long as one want in the morning!

I don't think this person has children :P

Maybe not 'exclusively' slept, but koalas[1] sleep for a majority of the day (16-20 hours) in order to digest highly toxic eucalyptus leaves which constitute the main portion of their diet. [1] https://en.wikipedia.org/wiki/Koala

Maybe I should really lean into that nap after eating..

Or quit eating poison :P

> So the ancient mystery of why we need sleep might have just been answered. I would be very surprised if sleep would serve only one purpose. In complex interconnected systems you usually don't get far with monocausal explanations.

TFA also acknowledges this: > There could well be many other functions that have since joined in with the sleep cycle (such as memory consolidation), but the authors hypothesize that mitochondrial function is the process that underlies all of them. If you need oxygen, then you need sleep!

Do plants sleep? Don't some insects, like flies, live without any sleep?

AI frenzy almost convinced me that sleep was the training of our neural network with all the prompts of the day. And now this /o\

Jesus christ, not even a biology thread is safe in the orange website.

Philosophers of mind have always tried to describe the brain using contemporary technology analogies. It's only natural and nothing to frown at.

Descartes compared the human mind to waterworks and hydraulic machines, other authors used mechanical clocks, telegraph systems, digital computers, and (in the recent decades) neural networks.

In the end it's all computing and to a degree all of those models serve as good analogies to the wetware, one just needs to avoid drawing wild conclusions from it.

I'm sure there will be new analogies in the future as our tech progresses.

We don't literally train on today's prompts while we sleep, but there actually _are_ some _computing_ tasks going on in our brains at that time that seem to be important for the system.

Workaholism is always just manifesting underlying psychical issues, be it some form of OCD, deep unhappiness with one's life and escapism from emptiness or similar. Such state manifests in many destructive behaviors, which then like in case of sleep create their own forces of destruction. One can't escape psychology, one thing no school taught me (and they should have since we all deal with this in some way! plus its…

I'd be careful with saying that is "always" the case.

What about people who are deeply passionate about their mission and chose to devote their life to it?

Increasing the count and efficiency of mitochondria is gonna be a big deal. ME/CFS is caused by these organelles not working as they should.

It’s not clear to me CFS is really a thing. To me it’s a catch all BS diagnosis that basically says “we don’t know what this is, so we’re calling it CFS”.

Highly recommend red light therapy for this. There's a spreadsheet that contains [1] all the scientific research does on effect on mitochondria. [1]: https://docs.google.com/spreadsheets/u/1/d/1ZKl5Me4XwPj4YgJC...

That’s a long list. Not all research is good research, or shows the effect you’re looking for. Where did this come from?

Do you use red light therapy? For what? How often? Where do you focus it? I did manage to get some red light masks although I find it hard to fit into my routine

Plants breathe out oxygen, like we breathe out the other one.
