One of the simplest and most effective exercises to improve mood is walking. Whether it’s a stroll in the park or a leisurely stroll through your neighborhood, walking can significantly enhance your mental health. Walking helps increase levels of endorphins and serotonin in the brain, which are chemicals known to improve mood. A study published in JAMA Psychiatry found that regular physical activity, such as walking, can reduce the risk of developing depression by 26%. Aim to walk at least 30 minutes every day. If possible, choose a path that has a connection to nature, as outdoor activities can further reduce stress and anxiety. Listening to soothing music or podcasts can also make the experience more enjoyable.
