I get the impression a big part is also just engagement, in a sense - social media is built to provide a constant stream of engaging content, keeping you hooked and anticipating the next thing.

Slowing down and doing something that isn’t so endlessly exciting might help, like watching a bit of a documentary, or reading a book (one that doesn’t however captivate you too much) seems like a decent idea, much better than doomscrolling or watching short form videos one after another.
