New content keeps me awake. ...but it also cannot be the same content every night, so I have a few hundred hours of several old shows hosted on my Plex server that I play each night. It's novel enough that it keeps my brain occupied, but not so new that I care about missing anything. It's a nice sweet spot. My next step is selecting very specific episodes that I think have good stories that I actually want to reinforce. I find I really internalize certain scenes if I happen to be in the correct part of my sleep cycle while it's playing.
