Everyone is different, and it's good to know your tolerance level for various stresses.
I do watch about 3 hours of televised news daily....couple hours of local in the morning, local noon news, local at 6 followed by national news for a half hour. I am not glued to the screen the whole time....usually on my iPad at the same time.
I see things come across my newsfeed during the day, and if I am curious or concerned, I research more online.
For me, it is better to know what is going on..that's my comfort zone. But I understand why some limit, and that's good they are taking care of themselves.
