eli5: How does lack of sleep kill someone?

In: Biology

Answer 1

It’s kind of like Disneyland: although you see some employees sweeping up during the day, all the deep cleaning and repairs can only happen when the park is shut down at night. If you don’t have that night shift to tidy things up, then the “unemptied trash” and “broken stuff” will build up pretty fast during the day and will overwhelm the park/body while business tries to run as usual.
