IIRC from Matthew Walker talking about it there doesn't seem to be any bad effect. If you're on a regular sleep schedule he noted it likely isn't necessary but if you feel it helps then it doesn't hurt. It would be best for when your circadian rhythm is off, like when you are jet lagged.

Are there any stars that are close enough to us that could supernova ( I don't know if I used that correctly) and have some kind of impact on us? Or are all of the stars big enough to do that not close enough. Is it possible we could ever witness one in the night sky, that would be wild.
