Meditate, go for long walks/hike, take some Epsom salt baths, read uplifting stories, listen to upbeat music, watch some good movies, don't isolate, and look into a new hobby.
Instead of reading/watching news:
Audit a course on Coursera, write short stories, paint, draw, DIY project,...
Ditto all of that, plus my favorite, “Make an animal friend today!”
