It does seem to help. I recently made a commitment to avoid digital media on my own.

I don’t think games or reddit or browsing is necessarily that bad in limited amounts. But it becomes too easy to start spending all your time on it because everything else feels too much effort and less fun.

I still allow myself any form of digital entertainment, but only when I do something together with friends. That way I still have some social contact, and I’ll have to do the effort to meet up if I want to do something fun.

When I’m by myself I’ll usually limit myself to reading, writing, going for walks, etc

Oh also, I snack a lot less and have lost weight. The initial reason I cut out media was in the evenings all I would do is snack and watch stuff until bed. And I NEVER actually felt ready for bed. Maybe I'd be tired, but there was some existential dread or something that I was wasting my life and not pursuing my interests.
