I seem to hear from a variety of people that they struggle to fall asleep at night; but the difficult to fall asleep sounds like an evolutionary downside. Even as hunter-gatherers, being able to sleep whenever and wherever sounds like it would be an advantage.
Is it a recent product of modern times and people didn’t actually struggle with it a while back? In which case, what of modern life is causing this? If not, what is the evolutionary advantage of not falling asleep easily?
I read a book long ago that talked about lights and how our bodies are programmed to fall asleep when it’s dark… but now we have street lights, indoor lights, etc. this was back when I read books on a Palm Pilot… 😔
