The actual cure to that crap is to fill your day with healthier activities so that you’ll end up surprising yourself you hadn’t browsed Instagram today.
I find that it does shorten. Of course infinite scroll still happens but with a ruthlessly curated feed, it seems like after about 5-10 minutes of browsing there's a tipping point where relevance drops off a cliff. That's when I know to close the app.
(I open IG maybe 1-2x a week, FYI)
My point is that there's also good that can come out of social media. Completely disregarding any social media as useless and a waste of time is wrong, in my opinion.
My point is to start blocking so that you can turn whatever social media of your choosing into an enriching experience, rather than a doom scrolling one.
But of course, even if you do so, we should all keep a limit on our internet consumption as a whole.
