What Your Biological Age Reveals
Enter your details above to estimate your Biological Age.
Biological Age vs. Chronological Age
The **Biological Age Calculator** provides an estimate of your body's true functional age, based on the cumulative impact of **lifestyle factors** like diet, exercise, and stress. Unlike your simple **chronological age** (time since birth), **biological age** reflects the health of your cells and organs. If your **biological age** is lower than your actual age, it indicates slower aging and generally lower risk for age-related diseases—a strong positive sign for **longevity**.
How Lifestyle Factors Influence Biological Age
The calculation is based on weighted factors where positive habits subtract years and negative habits add years:
- **Smoking:** Adds the most significant penalty, accelerating aging.
- **Exercise & Diet:** High exercise levels and a healthy diet significantly reduce your **biological age**.
- **Stress & Sleep:** Chronic **stress** and inadequate **sleep** introduce metabolic strain, increasing your apparent age.
- **Alcohol:** Moderate consumption has varied effects, but high weekly consumption adds risk.
The goal is to use this **true health age** as a benchmark. Consistent positive changes to your habits can demonstrably reduce your future **biological age** score and support **anti-aging** health.
Biological Age FAQs
**Metabolic age** typically relies on body composition (like body fat percentage) to estimate the age of your metabolic function. **Biological age** takes a broader approach, incorporating **lifestyle factors** like **stress**, **sleep**, and **diet** alongside general health, offering a more holistic view of your **true health age** and potential **longevity**.
Yes. Since the calculation is based on controllable **lifestyle factors**, improving poor habits (e.g., quitting **smoking**, increasing **exercise**, reducing **stress**) will result in a lower estimated **biological age** in subsequent calculations. This reflects genuine positive changes at the cellular level that contribute to **anti-aging** and better overall health.
Chronic **stress** leads to consistently high levels of cortisol, which is linked to increased inflammation, impaired immune function, and accelerated shortening of telomeres (markers of cellular aging). Therefore, managing **stress** and ensuring adequate **sleep** are critical components in maintaining a younger **biological age** and promoting **longevity**.
