Biological Age Calculator
Healthy Age Score by checkit.health
What is biological age?
Chronological age is how long you’ve been alive. Biological age estimates the condition of your body based on lifestyle and health markers. Two people the same age can have very different biological ages depending on their habits.
How this estimate is calculated
We start from your real age and apply transparent, evidence-informed adjustments for smoking, physical activity, BMI, sleep, alcohol, diet and stress. It’s a simplified educational model — a nudge to focus on the habits that matter most, not a clinical measurement.
Habits that lower your body age
The biggest wins are usually: not smoking, moving most days, sleeping 7–9 hours, keeping a healthy weight, staying within alcohol guidelines and eating plenty of fruit and veg. Small, consistent changes add up.
