Mornings that I spend from the minute I open my eyes glued to my phone screen leave me feeling basically the opposite. My attention is completely fractured. My general sense that I'm okay is harder to access and instead I often feel baseline anxiety and uneasiness. I feel less patient and more judgemental.
I can't claim that this causes me to be more caustic online (and offline) with people that I disagree with, but I certainly can see why that might be true. Especially when I'm bombarding my mind with divisive, provocative news headlines that are designed to get a rise out of me.
