Wondering, which would you consider healthier, an hour scrolling on the phone or an hour watching a tv show (either a fictional one or talk show, either with commercials)?
(aside from this, fascinating math ;))
Whichever one you are more likely to do with friends and family, I'd say. IME that's TV because we're experiencing the same thing.
If you're alone, it's probably a wash.
It's hard to say because it depends on what you're looking at too, of course.
But doomscrolling seems to teach your brain to never pay attention to anything for more than a few seconds, while at the same time being more exhausting than watching TV.
So I'd say the TV is healthier.
