 melatonin is, you know, if you see some like video on or like some article on like how to get better sleep or even like in the mainstream people might say like, oh, you need to limit the amount of blue light exposure that you get. There's a strong like scientific reason for that and that's because like the senses for blue light in our, in our eyes, if they're activated it inhibits the production of melatonin. So like, you know, that makes sense. You don't want to be inhibiting melatonin when you want to get sleepy. I think it's a lot to do with like, you know, sort of later in the day, you might get a little bit more blue light, you know, when it comes to like evening or like twilight, whereas in the morning you'll have more of like a reddish kind of orange light. I think that's that's one of the ways that like our body like regulates that. And sometimes also why it can be difficult, especially if we're isolated in dolls.
