Do a walking meditation
Not the sit-and-zen-out type? Here’s an exercise from Morgenstern that still gets you in the moment and out of your head: As you stroll, engage your senses. Note what you see (buildings with interesting shapes), what you hear (the rustling of leaves), and what you feel (the breeze on your face). Bonus points if you’re out in nature; it’s more likely to decrease rumination than being in an urban area, per a study published in Proceedings of the National Academy of Sciences.
