Question

How long can a single blink be before it's considered to be sleep?

Answer 1

5 minutes

Answer 2

You are only considered asleep if you're unconcious... Your eyes dont even have to be closed for you to be asleep! So close them all you want, your not asleep til your unconcious. And if you keep your eyes closed for more than a few seconds thats not a blink anyway

Answer 3

A blink can be considered sleep i gues if you blink for about 2 hrs or so. It seems weird to consider a blink sleep in my opinion. There is a science to whether something is sleep or not, but im not a doctor and am not searching wikipedia.

Answer 4

You can close your eyes for as long as you want but you're not asleep until you are actually asleep!
