When it comes to teens and their friend groups it's even more complicated than that. The same basic activity on the same platform could be worlds apart depending on the real world group dynamics. Still, I think at a certain point (with 4 hours per day surpassing that point IMO) it's hard to argue the activity remains beneficial. I'm not sure how someone would have time to do an actual hobby and spend a literal 4 hours per day on hobby social media groups, unless they're so wealthy they don't need to work, or they're not taking care of their health e.g. sleeping too little. So I don't think it would be a terrible public health thing to encourage people to set personal social media time limits (on average), even if it may be premature scientifically to say much specifically. Of course it's critical to not pretend that research is further along than it actually is in any sort of proactive public health PSA.
