What’s the science behind someone being a “light sleeper”?
In: Biology
I read that all humans have internal clock, but it run on different speeds for everybody.
There’s an “internal second” – it’s interval that out body think have a 1 second length, but in reality it could be anywhere from 0.7 to 1.2 seconds.
People with shorter values need less sleep, because their brain process things faster than for people with longer intervals.
There is a test that allow you to measure it – it will ask you to measure time intervals without help of clock and then show you your value. I was passing it ~20 years ago in university.
