Frequently asked questions
What does HealthRating.org calculate?
HealthRating.org combines 14 in-depth assessments — body composition, diet, exercise, sleep, mental health, environment, family history, and more — into a single health score, plus estimates of your life expectancy, biological age, cardiovascular risk, and type 2 diabetes risk.
Is HealthRating.org free and private?
Yes. All assessments are free with no sign-up required, and your answers never leave your browser — nothing is sent to any server.
Is the health score scientifically grounded?
Every factor is weighted using published, peer-reviewed research — over 60 studies including Chetty et al. 2016 (income and longevity), Holt-Lunstad 2010 (social connection), and the FINDRISC diabetes screening questionnaire. It is an educational tool, not a medical diagnosis.
How is biological age different from life expectancy?
Life expectancy estimates how many years you may live based on your current habits and risk factors. Biological age expresses the same signal differently: whether your body is effectively younger or older than your calendar age.
This tool provides educational estimates based on population-level research. It is not medical advice and does not replace consultation with a healthcare professional.
