The immediate effects of exercise on mood are generally positive, leading to increased feelings of happiness and reduced stress levels. Physical activity stimulates the release of endorphins, known as "feel-good" hormones, which can improve mood and create a sense of well-being. Furthermore, regular exercise can help alleviate symptoms of anxiety and depression, thus enhancing mental health in the short term. Consistent physical activity triggers brain changes that promote resilience against stress, contributing to an overall improvement in emotional health.
