research studies on exercise

Research on exercise shows it benefits physical and mental health by improving heart function, strengthening muscles, and boosting mood through endorphin release. Studies indicate regular physical activity can reduce risks of chronic conditions like diabetes, hypertension, and certain cancers. Exercise also enhances cognitive function, memory, and sleep quality. The optimal type, intensity, and duration vary, but consistent movement—such as walking, cycling, or strength training—typically leads to better health outcomes. Overall, science supports that staying active is a key factor in maintaining overall well-being and preventing disease.
