Biological Age vs Chronological Age: How to Measure and Improve Your True Age
Your driver's license says you are 45, but what if your body is functioning like a 55-year-old? Or better yet, a 35-year-old? This is the difference between chronological age and biological age—a measure of how well your body is actually aging.
What Is Biological Age?
Biological age represents how old your body actually is based on various physiological markers, as opposed to chronological age, which is simply how many years you have been alive.
The Key Difference
Chronological Age = Time since birth | Biological Age = How your body has aged
You cannot change your chronological age, but you CAN influence your biological age.

Try the Biological Age CalculatorHow Is Biological Age Measured?
- Epigenetic Clocks: Analyze DNA methylation patterns
- Telomere Length: Protective caps on chromosomes that shorten with age
- Biomarker Panels: Blood tests measuring inflammatory markers, glucose, lipids
- Physical Function Tests: Grip strength, walking speed, VO2 max
What Accelerates Biological Aging?
- Smoking (accelerates aging by 2-4 years on average)
- Heavy alcohol use
- Poor diet
- Sedentary lifestyle
- Chronic stress
- Poor sleep
Strategies to Lower Your Biological Age
- Optimize your diet (Mediterranean pattern)
- Exercise regularly (150+ min moderate or 75+ min vigorous per week)
- Prioritize sleep (7-9 hours per night)
- Manage stress
- Maintain social connections
