I did not see any proposed mechanism for less sleep reducing your need for sleep. (If I missed it, please let me know).
We lack a good idea of why the need for sleep exists in the first place.
If we sleep because there was little to do 100,000 years ago when it’s dark outside and we want to reserve energy, it makes sense to modulate to have a mechanism that modulates the amount of sleep so that people sleep more when it’s dark outside for longer.
I can’t do that with sleep without chemical help, except perhaps delay sleeping for a few hours or sleep a few hours late.
That’s not true. Humans are capable to set intentions to wake up at certain times and wake up at that time. You might personally not have conscious access to the underlying processes the same way you can avoid eating but that doesn’t mean that they aren’t there.
Yep, I sometimes manage to ask my body to wake up at a certain time and it does it when there’s something I care a ton about waking me up a few minutes before the alarm.
