Literature of old makes reference to "second sleep." Essentially people routinely got up in the middle of the night for whatever reason. Tend to a fire or livestock, IDK. Then they would have their "second sleep."
So perhaps we are more genetically wired for a different rhythm.
I do know that stressing about not sleeping only exacerbates the problem. Knowing that even laying there awake brings many of the benefits of sleep, helps me so I don't stress too hard about not falling asleep.
