Regular exercise can have considerable psychological effects on mood, including reducing symptoms of depression and anxiety while enhancing overall emotional well-being. Physical activity stimulates the release of endorphins, often referred to as "feel-good" hormones, that contribute to a sense of happiness and relief from stress. Additionally, engaging in regular exercise can enhance self-esteem, promote better sleep, and create a sense of achievement, all of which positively influence mental health and overall quality of life.
