Question

What’s the science behind someone being a “light sleeper”?

In: Biology

Answer 1

I sleep all the way through the night without waking up, *maybe* five times a year. I typically wake up a minimum of two times, but I would say 3 is typical. And that’s with earplugs and a cold dark room. I don’t drink caffeine in the afternoon, I don’t drink alcohol at all. I’ve just always been like this since I was a kid. Fucking sucks man.
