Sleep has crucial role in survival and well-being
- jajko 2y agoYeah but what role? 24h always at least a bit running brain has also crucial role in survival. I get some form of maintenance is needed, but 8h every day seems like an overkill for very significant disadvantages. Many other mammals require significantly less sleep.
- Agentus 2y agoAccording to sleep scientist mathew walker, it serves multiple roles, replenishment of resources obviously, but also behavior refinement (whatever you practice during the day gets practiced excessively while asleep), and sleep also is a creative and solution search. He mentions that sleep is so crucial that despite how vulnerable it makes organisms to be debilitated 8 or whatever many hours a day, what it provides more than counterbalances that massive evolutionary vulnerability.
- aeyes 2y agoCould it be that 8h is a "modern" sleep pattern? You can also take several shorter naps throughout the day (polyphasic sleep pattern). But to be honest, without light there isn't much humans can do at night.

- HarHarVeryFunny 2y agoIt seems that the brain needs sleep for maintenance/cleanup purposes to process and file away memories of the days activity. Animals also burn less calories when asleep, meaning they need less food to survive. Any change to sleep less would need to have major benefits of offset the loss of this benefit, as well as only being possible if the "maintenance" need for sleep were reduced or eliminated.
- interludead 2y agoFor humans, the benefits of adequate sleep, like improved focus, emotional regulation, and overall health, tend to outweigh the potential disadvantages.
