The impact of regular aerobic exercise on mood is well-documented. Engaging in activities like running, swimming, or cycling triggers the release of endorphins, often referred to as "feel-good hormones." This biochemical response can lead to improved emotions and reduced feelings of anxiety and depression. Regular aerobic activity also enhances self-esteem, fosters social connections, and promotes better sleep, further contributing to an overall positive state of mind. Consistency in exercise can create lasting mood improvements.
