eli5 why can’t people fall asleep when there’s a lot of noise
In: Biology
Evolution. Our caveman ancestors who found quieter (therefore secluded) places to sleep out-survived people who did something as vulnerable as sleeping in places with lots going on. More survival = outbreed the competition.
Fast forward a few thousand years and here we are, all descended from the ones who couldn’t sleep in noisy places and risk getting ambushed, eaten or stabbed or something.
It’s easy to forget or not realize that behaviors and instincts are evolved just like legs and organs are. Brains are physical too!
