Estimate your true biological age based on lifestyle factors

Basic Information

What is Biological Age?

Biological age, also known as physiological age, measures how well your body has aged compared to your chronological (calendar) age. While chronological age simply counts the years since birth, biological age takes into account how your lifestyle, environment, and genetics have affected your body's actual condition.

Someone with healthy habits might have a biological age younger than their chronological age, while someone with poor lifestyle choices might be biologically older than their years.

Biological Age vs Chronological Age

Understanding the difference between these two types of age is crucial for assessing overall health:

  • Chronological age: Fixed, based purely on your birth date
  • Biological age: Variable, influenced by lifestyle choices and can be improved

Research shows that lifestyle modifications can reduce biological age by several years, even within a few months of making changes.

Factors That Affect Biological Age

The main factors that influence biological age include:

  • Exercise frequency and intensity
  • Diet quality and nutrition
  • Sleep duration and quality
  • Stress levels and management
  • Smoking and alcohol consumption
  • Body weight and BMI
  • Social connections and mental health

Frequently Asked Questions

Biological age, also called physiological age, measures how well your body has aged compared to your chronological age. It takes into account factors like cellular health, organ function, and lifestyle habits. Someone with a biological age lower than their chronological age is aging well, while a higher biological age suggests accelerated aging.
Online biological age calculators provide estimates based on lifestyle factors and general health indicators. For a truly accurate biological age measurement, clinical tests are needed, including blood biomarkers, DNA methylation tests, and organ function assessments. Our calculator offers a useful approximation based on well-researched aging factors.
Yes, research shows that biological age can be reduced through lifestyle changes. Regular exercise, a healthy diet rich in fruits and vegetables, adequate sleep (7-9 hours), stress management, maintaining a healthy weight, and avoiding smoking can all help lower biological age. Some studies show improvements in just a few months.
The most significant factors affecting biological age include: smoking status (adds 4-10 years), exercise frequency (regular exercise can reduce age by 2-5 years), diet quality, sleep duration, stress levels, BMI, and alcohol consumption. Genetics also plays a role, but lifestyle factors are more controllable.
Biological age is a comprehensive measure of overall body aging, while metabolic age specifically refers to how your metabolism compares to average metabolic rates for different age groups. Metabolic age is calculated using basal metabolic rate (BMR) and is just one component of biological age.
