Have you ever felt overwhelmed and feel like you need to take a break? That's a perfect time to take a stroll right? Well, to make yourself feel even better- -add a little swing to your arms as you walk. "The brain learns through conditioning, so moving in a way you associate with happiness or pleasurable experience (for example, swinging your arms like you did when you were a child or even skipping) will 'biotranslate' into an automatic rise in feel-good endorphins," explains Lee Berk, Dr. Ph., a researcher in the psychology of positive emotions.
