What Is Biological Age and Why Does It Matter?

Biological age differs from chronological age. While your chronological age is simply the number of years you have been alive, your biological age reflects how your body is actually functioning. Your lifestyle choices can make your body function younger or older than your calendar age. The five key lifestyle factors are exercise frequency, diet quality, sleep duration, stress management, and whether you smoke. Improving these factors can significantly lower your biological age. In medical research, biological age is often tested using DNA methylation clocks, but this calculator provides a highly accessible, lifestyle-based estimate to help you understand your health trajectory.
