What is healthspan and its significance?

Healthspan is the period of one's life spent in good health, free from serious diseases and disabilities. Unlike lifespan, which measures the total years of life, healthspan emphasizes the quality of those years. Experts like Peter Attia argue that healthspan encompasses physical, cognitive, and emotional well-being. It addresses one's ability to move, think clearly, and maintain emotional health, thereby greatly influencing overall quality of life 1.

The significance of healthspan lies in its focus on quality rather than just quantity of life. An extended healthspan ensures individuals can remain active, engaged, and relatively free from pain and dysfunction as they age. Emphasizing healthspan over lifespan can lead to improvements in both areas since maintaining good health often naturally leads to increased longevity 2 3 2. Implementing strategies such as proper nutrition, exercise, and stress management are key to enhancing healthspan, making longevity a more vibrant and fulfilling experience rather than merely a prolonged lifespan 1 4
