Health Span

Health span refers to the length of time a person lives in good health, free from chronic diseases and serious disabilities. Unlike lifespan, which measures the total years lived, health span emphasizes quality of life during those years. The goal is to maximize the number of years spent feeling well, active, and independent, reducing the period when illness or functional decline occurs. Increasingly, research focuses on lifestyle choices, nutrition, and medical advances to extend health span, helping people enjoy a more vibrant, healthier life well into old age.
