It's not that I think it is risky; there's probably no risk at all from making a room darker when you go to sleep. I know people who can't sleep without a sleeping mask and they've been alternately skinny and fat all the same. What I'm asking is whether that test, as an individual, can actually prove anything? What you think is an actual effect might not be any effect at all. Without something more rigorous, your "test" is that of a magician. It's easy to forget how suggestible we are as humans. Do you believe that if you pray to god to confirm himself to you and you feel a "burning in your bosom" that the Book of Mormon and the LDS church are right about reality?
