YOU ALREADY know that a bad diet and a permanent indentation on the couch aren’t good for your brain. But there are some lesser-known daily routines that could be undermining your cognition, says Jessica Caldwell, a neuropsychologist and director of the Women’s Alzheimer’s Movement Prevention Center at the Cleveland Clinic.

She suggests that the next time you’re overtaken by negative thoughts, you should:

Make a list of five specific things that you are grateful for, and focus on those.

Greet a negative thought when it pops up with “hello,” then verbally tell it “goodbye.”
