Healthspan refers to the period of life during which an individual remains healthy and free from serious disease or disability. It emphasizes not just the length of life, but the quality of life, focusing on maintaining physical and mental well-being as one ages. A longer healthspan means more years spent in good health, allowing individuals to engage in activities they enjoy and maintain independence. Factors that influence healthspan include genetics, lifestyle choices, and environmental conditions. Regular exercise, a balanced diet, and social connections can contribute to a longer healthspan. Research in areas like gerontology and preventive medicine aims to identify ways to enhance healthspan and promote healthier aging.
