Exercise releases endorphins throughout your body, creating feelings of happiness. While many people find it hard to motivate themselves to exercise, the mood boost you get after exercising is worth the effort. Researchers from Penn State found in a recent study that people who were more physically active had more pleasant- activated feelings than people who did not exercise. Additionally, exercise energizes you, helps you feel less stressed out, boosts your confidence, and can even fight insomnia. Any physical activity that gets you to break a sweat helps you build happiness—even a brisk walk works! So get that blood pumping and get happy.
