What is your Health Age?
Your health age is an estimate of how old your body is, based on your lifestyle, compared with your actual age. Answer a few questions to see yours. It is a starting point; your real biological age comes from your blood.
How is your Health Age calculated?
We start from your actual age and add or subtract years using an open, evidence-informed set of lifestyle factors. Nothing is hidden. Here is exactly what moves the number:
- Smoking: the single biggest lifestyle factor
- Body Mass Index (height and weight)
- Physical activity each week
- Diet quality (wholefoods vs processed)
- Sleep duration
- Alcohol intake
- Stress level
- Blood pressure status
- Family history of heart disease or diabetes
This is an educational estimate, not a medical diagnosis. It cannot see what is happening inside your body; only a blood test can.

- Inflammation (hs-CRP)
Common questions
What is health age?
Your health age is an estimate of how old your body is, based on your lifestyle, compared with your actual age in years. Healthy habits can make your health age lower than your years; risk factors such as smoking, poor sleep or excess weight can make it higher.
Is the LabONE Health Age accurate?
It is an educational estimate from lifestyle factors, not a medical diagnosis. For your true biological age, a blood test that measures markers such as ApoB, fasting insulin, HbA1c and inflammation gives a far more precise picture. That is what the LabONE Longevity package is for.
Is my data private?
Yes. The calculator runs entirely in your browser. Your answers are never sent to LabONE and are not stored anywhere.
How can I lower my health age?
The biggest levers are not smoking, exercising regularly, eating a wholefood-rich diet, sleeping 7-8 hours, managing stress, and keeping blood pressure and weight in a healthy range. A blood test shows which markers to focus on first.
