It's worse with shorts as you don't even think "just one more" as consuming a single short is so "effortless"/"short" that you might not think about them in singularity and instead think "just a few more".
The youtube/tictok shorts are a genius form of getting the human brain hooked.
It's similar to how eating a piece of cake can make you feel guilty so instead you switch to a bag of M&Ms or other such small sweets thinking it's better for you as "I'll only have a few", and before you know it, you've eaten the whole bag in one go which is worse than the single piece of cake would have been.
I've found watching long content is better to keep such addictions in check. When I've finished watching a 2h long movie, I feel also "done" and ready for bed vs the endless stream of streaming shows, youtube videos and other social media shorts can keep you hooked for days on end.
