How Does the Biological Age Calculator Work?

Your biological age is an estimate of how old your body seems based on various lifestyle and health factors. While your chronological age simply counts the years since birth, biological age considers how well your body functions.

This calculator evaluates factors like exercise habits, smoking status, BMI, sleep quality, diet, stress levels, and alcohol consumption to estimate your body's true age. Each factor can add or subtract years from your chronological age.
