2. Distract yourself

Taking your mind off of the thought your brain is chewing on can bring a lot of relief. Dr. Magavi is a fan of puzzles in particular. "Puzzles can improve mindfulness and overall mood states," she says. "They can divert attention from painful rumination. Some studies indicate that puzzles can minimize brain cell damage and facilitate the growth of new neurons."

Other activities might be checking in with friends and family, playing a sport, or exercising. Re-engaging in hobbies and interests that bring you joy can be effective, too.
