How We Calculate Your Health Age

The calculator evaluates six core health dimensions: sleep quality, physical movement, nutrition habits, mental wellbeing, recovery, and daily lifestyle factors. Each dimension contributes to a composite health score mapped against age-adjusted benchmarks.

Sleep and movement carry a 1.5x weighting because research consistently identifies them as the strongest predictors of healthspan and longevity. Poor sleep alone can accelerate cellular aging by several years.

If you provide optional lab values, the algorithm incorporates these as precision modifiers. Your biological age offset is calculated by comparing your weighted score to the expected score for your chronological age.

Common questions

What is biological age?

Biological age reflects how well your body functions compared to your chronological age. Someone who exercises regularly, sleeps well, and manages stress may have a biological age years below their actual age — meaning their body performs like a younger person.

How do I calculate my body age?

Answer 15 lifestyle questions covering sleep, movement, nutrition, mental health, recovery, and daily habits. Optionally add lab values like resting heart rate or blood pressure for extra precision.

What is a good health score?

A score of 70+ is solid. Scores above 85 suggest your body is functioning significantly younger than your age. Most people land between 45 and 70.

Can I lower my biological age?

Yes. Sleep quality and consistency have the fastest impact — often within 1–2 weeks. Regular exercise, better nutrition, and stress management compound over months.

What habits make you age faster?

Chronic sleep deprivation, sedentary behavior, high stress, smoking, excessive alcohol, poor nutrition, and social isolation are the strongest accelerators of biological aging.

How accurate are online health age calculators?

Self-reported quizzes give a useful directional estimate — not a clinical diagnosis. This calculator is designed to highlight which habits to focus on, not replace a medical assessment.
