I listen to ambient nature noise (thunderstorms are a favorite) with noise-canceling headphones while laying in bed.
Still technically electronics, but it doesn’t require any active attention, so it does a great job at transitioning my brain to a state where falling asleep is easy, while still being stimulated enough in the meantime to avoid being restless/bored.
For anyone that doesn’t know, SponsorBlock is just a extension where someone marks a part of video as:
You can then set what it’ll do for each caregory: auto skip, put a button you click to skip, color the seek bar, or obviously just do nothing but let the video continue normally.
It’s so nice, I actually use it most for auto-skipping intermissions in recordings of live content these days… It even records how much in total: I’ve skipped 9688 segments (totalling 14 days 15 hours 3.5 minutes) since I installed it.
