Biological Age Calculator

Biological age estimates how old your body functions compared to average population. It differs from chronological age (years since birth) and is influenced by genetics, lifestyle, diet, exercise, stress, and environmental factors.

Clinical biological age uses biomarkers: epigenetic clocks (DNA methylation), telomere length, blood markers (inflammatory markers, metabolic markers), and functional tests (grip strength, VO2max, cognitive tests). This calculator uses lifestyle proxies.

Research suggests biological age can be reduced through regular exercise, healthy diet, adequate sleep (7-8 hours), stress management, smoking cessation, moderate alcohol consumption, and strong social connections. Some studies show 3-5 years of biological age reduction with lifestyle changes.

The factors with the largest evidence-based impact on aging are: smoking status (cessation can reduce biological age significantly), regular exercise (especially combined strength and cardio), diet quality, and sleep. Social connection and stress management also play important roles.
