I’m with you. My go to is a podcast called “The Science of Everything” by James Fodor. He does a fantastic job explaining so many things - it almost feels mean to say I love falling asleep to it. It just means I’ve listened to so many episodes over and over. It’s the right amount of stimulation and engagement to relax me from my day until sleep takes over.
Now, falling asleep with AirPods in every night? Maybe not the best habit. But I know it works when I need it to.
