Health Age Questionnaire Calculator

Your health age (also called biological age) is an estimate of how old your body and cardiovascular system appear based on lifestyle and risk factors, rather than how many years you've been alive. If your health age is lower than your real age, your habits are working in your favour. If it's higher, there may be lifestyle changes that could meaningfully reduce your risk of disease and extend your life.

This calculator provides an evidence-based estimate using well-established risk factors such as smoking, blood pressure, cholesterol, weight, diet, exercise, and stress. It is not a clinical diagnostic tool and cannot replace a consultation with your doctor. The results are most useful as a general guide to help you identify which areas of your lifestyle have the greatest impact on your long-term health.

Smoking, physical inactivity, high blood pressure, poor diet, obesity, and unmanaged stress tend to have the largest negative effects on health age. Conversely, regular exercise, a healthy diet, not smoking, maintaining a healthy weight, and strong social connections are among the most powerful ways to lower your biological age.

Yes — many of the risk factors that increase health age are modifiable. Quitting smoking, increasing physical activity, improving your diet, managing blood pressure and cholesterol, and reducing chronic stress can all reduce your biological age over time. Even moderate lifestyle improvements can result in meaningful gains in life expectancy.

Genetics play a role in longevity, particularly when multiple close relatives (parents and grandparents) have lived well into old age. Having long-lived family members suggests a genetic predisposition to a longer, healthier life. However, lifestyle choices remain the dominant factor and can either support or counteract your genetic tendencies.

This calculator is designed for adults aged 18 and over who want to understand how their lifestyle is affecting their long-term health. It is particularly useful for people looking to make positive changes and wanting a starting point for understanding their personal risk factors. People with existing cardiovascular disease or complex medical conditions should consult a doctor rather than relying solely on this tool.

Chronic stress is linked to elevated cortisol levels, increased inflammation, poor sleep, and higher rates of cardiovascular disease. People who report persistently high stress levels tend to have measurably worse health outcomes. Managing stress through relaxation techniques, exercise, therapy, or improved social connection can reduce its impact on your biological age.

It's a good idea to recalculate every 6 to 12 months, or whenever you make significant lifestyle changes — such as quitting smoking, starting a regular exercise routine, or significantly improving your diet. Tracking your health age over time gives you a tangible measure of progress and can be a powerful motivator to maintain healthy habits.
