Other things that are regularly close to my face: my glasses, several pillows in my bed, my fork as I eat, my children as I hug them.
Of course, my children can also jam their face into mine when they're being all manic and running around and that's not fun
But clearly, there is a big difference between "things I choose to put in front of my face" and "things that appear in front of my face outside of my own agency".
Similar to how you can't tickle yourself.
That wasn't even hard to figure out. First 15 minutes of the day, haven't gotten out of bed yet, with my phone in my face.
I also find it interesting how these sorts of articles never talk about reading books. I find that reading novels too much can also give me feelings of being stuck, not wanting to do anything else, just trundling along doing the same activity over and over again. It's how I got through all 9 books in The Expanse series in only a couple of months.
The problem isn't screens or light or not seeing the sky. It's over indulgence in consumption. It's just plain ol' addiction.
