Biological Age Calculator

This calculator provides an estimate based on well-researched lifestyle factors. True biological age testing requires blood biomarkers, DNA methylation analysis, or other clinical tests. Use this as a general indicator of how your lifestyle affects aging.

Yes! Research shows that lifestyle changes can reduce biological age markers. Exercise, quality sleep, stress management, and healthy diet have all been shown to slow or reverse biological aging in clinical studies.

Smoking has the largest negative impact, adding up to 10+ years. For non-smokers, lack of exercise, chronic stress, and poor sleep are the biggest accelerators. Exercise is the most powerful positive intervention.

Fitness age specifically measures cardiovascular fitness and its impact on longevity. Biological age is broader, encompassing cellular health, organ function, and multiple lifestyle factors beyond just fitness.

Loneliness and social isolation increase inflammation, weaken immunity, and raise cortisol levels - all of which accelerate aging. Strong social ties are consistently linked to longevity across cultures.

The sooner the better! Aging processes begin in our 20s and 30s. However, it's never too late - studies show significant improvements in biological markers even in people who adopt healthy habits in their 60s and 70s.

Recalculate every 3-6 months as you make lifestyle changes. Biological age can change relatively quickly with sustained behavior changes - some people see improvements within weeks of adopting healthier habits.
