Frequently Asked Questions
- What is biological age and how is it different from chronological age?
- Chronological age is simply how many years you have been alive, while biological age estimates how old your body actually functions based on health markers. Someone who is 45 chronologically could have a biological age of 38 if they are very fit, or 52 if they have poor cardiovascular health. It is a composite score based on metrics like VO2 max, resting heart rate, body composition, and grip strength.
- Can you actually lower your biological age?
- Yes, research consistently shows that regular exercise, quality sleep, a nutritious diet, and stress management can improve the biomarkers that determine biological age. Improvements in cardiovascular fitness and body composition have some of the largest effects. Many people see measurable improvements within 3 to 6 months of consistent lifestyle changes.
- How accurate are online biological age calculators?
- Online calculators provide a useful approximation based on well-studied health markers, but they are not as precise as clinical tests like DNA methylation analysis. They are best used as a motivational tool to track trends over time rather than as a definitive medical assessment. For a clinical-grade result, consult a healthcare provider who offers epigenetic testing.
