I like to listen to podcasts/youtube videos about religion. The two I use the most are Religion for Breakfast and Let’s Talk Religion. I also sometimes listen to “Fall of Civilizations Podcast”. I always get bored if I do nothing but listen to podcast, which helps me sleep.

I do wish I could listen to that last one though, since I like history and the production quality is good. A video can hold my attention for longer than a podcast for some reason.
