I’ve done something counterintuitive to ease news anxiety: Turned on news notifications on my phone.
If the news notifications look like the usual baloney, then I know there’s no crisis requiring my immediate attention.
I used the same principle immediately post-9/11 with the technology available at that time. I had my clock radio tuned to wake me up with news radio. If the first words I heard were “Michael Jackson,” I knew there was no reason for me to rush to look at headlines.
