I have seen tons of threads that talk about reverse blinking as a good way to go to sleep really fast, and I have tried it. It definitely works to some extent (not as much as some people say it does), but no matter how much googling and searching I do to find out how it's supposed to work, but I just can't seem to find anything. All I find are either saying that it is one of the best things to ever exist or that it doesn't seem to work for them.

So my main question is: Is there any reason that reverse blinking should work? Any studies to back it up? What is going on in the brain when you do it?
