This is probably a strange comment, but this morning, I uninstalled a game called Ingress. It's a mobile game similar to Pokemon Go (made by the same company, Niantic) except you capture the "pokestops" called "portals" in this game and defend them and destroy the other teams' portals. There are two global teams, blue and green.
I installed it as a way to play with my gf, and I didn't realize I joined the (globally and locally) losing team, green, to be on her team. In about 11 days since installing it, I've advanced to just before level 7, the level before the last (level 8) with significant powerups. By contrast, my gf reached that level after about a month and a half of play. In these last 11 days, I've tracked around 70 to 80 km (~47 mi.) of walking and I've lost about 3 lbs.
While some of that is great for my health (been trying to slim down), I had become quite anxious. Being on the losing team (by a factor of two in terms of control of portals and area in the city, it was a factor of ten the day I started), I had literally become paranoid throughout the day that any moment, a notification would come in that the portals I controlled would come under attack, and I would have to defend them. Given we were on the losing team and the winning team had more resources, it was a challenging but exciting fight. A few of the advanced green players had taken out time to give me rare items when they observed my advance.
I'd been thinking of just stopping thus despite how much fun it was and how much I love walking and seeing my city in general. When I saw this article this morning, I kid you not; sure it was kind of cheesy, but it triggered a few minutes of introspection and I eventually decided to uninstall the app for now.
So, no, I'm probably not going to turn off all notifications and be crazy like the author (I have ig notifications off for likes and don't get frequent notifications in general), but at least for me, articles that at least raise the awareness of such issues do at least push some people ever so slightly in the right direction. It actually did it for me.
