Outdoor exercise has a profound impact on mood and mental well-being. Engaging in physical activity outdoors can boost levels of serotonin, a neurotransmitter linked to happiness, reducing symptoms of anxiety and depression. The natural environment, along with sunlight exposure, contributes to a greater sense of vitality and can improve sleep quality. Studies indicate that people who exercise in green spaces report higher levels of overall satisfaction, reinforcing the mental health benefits of outdoor activity.
