The thing with these moon hygiene tips is that they often work in a really subtle way - not because the moon actually does anything, but because you believe in it and then pay more conscious attention to your sleep. Maybe you go to bed earlier, you look at your phone less because you want to "live in harmony with the moon." That's the placebo effect, and it actually works, but not because of the moon. The annoying part is just: when you notice it's helping, you never know if it's because of the actual habits or because of the mumbo jumbo - and then you end up spending money on some lunar tracker app, even though a regular alarm clock and consistent sleep times would do the same thing.
I wouldn't read too much into it, honestly - the idea that the moon directly affects your sleep quality isn't scientifically sound. What actually helps are more mundane things like consistent sleep schedules, less phone time before bed, and a dark room. That said, if a horoscope like that helps you psychologically and lets you relax better, it doesn't hurt - the placebo effect is real. Are you dealing with sleep problems right now, or are you asking more out of general curiosity?
