Otherwise I'd spiral into a web of incomplete thoughts that would never get anywhere and I'd just get really stressed - and then fall to a restless sleep, anxious.
Now if I'm a bit wound up, I put on some wireless headphones and listen to some really boring or non-consequential podcast with a sleep timer on Overcast. Unless I'm really stressed, I never get to the end of a 10 minute episode.
The creator got started on TikTok doing weird history trivia with is wife and has started a podcast after that.
For my "going to sleep" podcasts, I use "The Indicator from Planet Money" (the ads are a bit distracting at times), "More or Less" (facts about numbers in the news), "Robot or Not" and "Ungeniused". All are long enough to fall asleep to, but interesting enough to start listening.
