Outdoor exercise positively affects mental well-being by promoting exposure to natural environments, which can improve mood and reduce stress. Engaging with nature can lower levels of cortisol and boost feelings of happiness and emotional resilience. Activities such as hiking, running, or practicing yoga outdoors not only provide physical benefits but also enhance mindfulness and connection to one's surroundings. Moreover, outdoor exercise often encourages social interaction, which can further boost mental health. All these factors collectively contribute to a holistic approach to exercise, supporting both physical and mental fitness.
