What is healthspan, and how is it different from lifespan?

Lifespan is how long you live. Healthspan is the portion of that life spent in good health and able to function well. The goal of healthspan is not simply more years, but more years with physical, metabolic, cognitive, and everyday capacity intact.

Healthspan and lifespan answer different questions

Lifespan is a count of years from birth to death. Healthspan is a broader concept about the quality and function of those years, including how long someone remains free from major disease burden or disabling loss of function. There is no single universal healthspan clock that can directly tell an individual how many healthy years remain. In practice, healthspan is better treated as a framework for tracking the modifiable systems linked to long-term function.

Healthspan is multi-factor by definition

Wellness Project Healthspan brings cardio, strength, Active Living, sleep, body composition, phenotypic age, metabolic health, and glucose health into one report so you can see which long-term health inputs look strong, which need more data, and which are worth working on.

Turn the idea of healthspan into measurable inputs.

Wellness Project connects your fitness, movement, sleep, body, and lab history in one Healthspan report without pretending to predict your lifespan.

A useful healthspan tracker should show its inputs

A single longevity score can look precise while hiding the evidence underneath it. Wellness Project keeps the factor-level measurements visible and leaves missing domains unassessed. That makes the report useful for action: you can see whether the next lever is cardio fitness, strength, everyday movement, sleep regularity, body composition, glucose, or lab follow-up rather than treating one opaque number as destiny.

See your Healthspan factors in one place.

Connect the data you already collect and Wellness Project will organize the supported factors, show what is missing, and keep the evidence behind each result visible.

Frequently asked questions

Is healthspan the same as longevity?+

They overlap, but they are not identical. Longevity usually refers to living longer, while healthspan focuses on how long those years are spent in good health and function.

Can healthspan be measured with one number?+

Not directly. Different products and researchers use different definitions and proxies. A more transparent approach is to track multiple health and function domains and show the underlying inputs.
