:That report is entitled "Brain may flush out toxins during sleep". Note the "may". Add it to the list of hypotheses.

− | The idea is that we do not know why we evolved to need sleep, when microorganisms do not sleep. If we had evolved without developing the need to sleep we'd also have evolved another way to retain memories and flush toxins. There is no truly biological reasons why a species would evolve the need to sleep when the option to be alert all the time is more obvious, as it means there is less risk of attack and danger.[[Special:Contributions/108.162.219.16|108.162.219.16]] 20:00, 21 March 2014 (UTC) | + | The idea is that we do not know why we evolved to need sleep, when microorganisms do not sleep.

:Apparently, one of the thing brain or body does while sleeping - reindexing memories, flush toxins, self-repairs, I think that the list of hypotheses is long - give us so big advantage when awake that the limited awareness (note that some noises can still wake us up) in period of sleep is worth it. Or, perhaps the alternative solutions are too hard to evolve. Remember that even while sleeping, humans are much more active that most microorganisms: it is probable that need for sleep evolved at the same time as the brain itself. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 12:54, 22 March 2014 (UTC) | :Apparently, one of the thing brain or body does while sleeping - reindexing memories, flush toxins, self-repairs, I think that the list of hypotheses is long - give us so big advantage when awake that the limited awareness (note that some noises can still wake us up) in period of sleep is worth it.
