it's kind of messed up that the bright light therapy lights that you turn on for a little while when feeling tired and sad actually work while also sounding entirely like a snake oil scam.
I'm only just now learning about these since i was born and raised in a place where everyone feared the sun and everyone got their lumens and whatever else in a few seconds and then avoided the sun as much as possible for the rest of the day so they didn't spontaneously get vaporized.
