IN OUR QUEST FOR A BETTER LIFE, many focus on lifespan — the number of years we can add to our existence. But what if we shifted our perspective from simply living longer to living healthier and more vibrant throughout those years? I want to talk about cracking the aging code with health span.

This shift in focus introduces us to the concept of healthspan, a measure of the quality of life we experience as we age.

In this essay, I will define healthspan and explore strategies for optimizing it, focusing on the following:

  • Diet
  • Physical activity
  • Stress management
  • Sleep
  • Avoiding harmful habits

Defining Health Span

Healthspan is a relatively recent term that has gained momentum in aging and longevity research. One common definition is this:

Health span is the period of life spent in good health, free from the chronic diseases and disabilities of aging. In other words, healthspan emphasizes longevity and maintaining a high quality of life throughout those years.
