Personally what I've found works for me is to focus on news that's local to me, the more local the better. So I start with news about my municipality, then my province, then my country, and I try to keep it at that for the most part. Of course, world news slips through, especially American politics, but I try to keep it at bay as much as possible.
I honestly had a bit of a nervous breakdown around the start of the war in Ukraine, doomscrolling through articles and updates everyday. I realized I needed to dial back and tried to cut out all news, and that just ended up making me more anxious. Focusing on local news has been the Goldilocks zone for me. I'll still consume stuff about world news occasionally, but it's usually in a way that relates to my country, for example articles about Canada's support of Israel on the world stage.
Some news sources are definitely more inflammatory than others. I'm also of the opinion that television news in general is a farce, to the extent that the best "journalists" on TV in recent memory have been comedians like Jon Stewart and John Oliver.
