What is Biological Age vs. Chronological Age?
Your chronological age is the number of years you’ve been alive. It’s a fixed number that marks the passage of time. Your biological age, on the other hand, is a fluid measurement of how well your body is functioning at a cellular and physiological level. It's your "health age" or "body age."
A lower biological age compared to your chronological age is a positive sign of healthy aging, while a higher number may indicate that lifestyle factors are accelerating your aging process. Knowing your biological age gives you the power to make informed decisions to improve your healthspan—the number of years you live in good health. Learn more in our Ultimate Guide to Biological Age.
The Key Factors That Determine Your Biological Age
Your biological age isn't just a number; it's a reflection of your daily habits. While genetics play a role, research suggests that up to 80% of your aging process is influenced by lifestyle and environment. Our calculator analyzes the following key areas:
Physical Activity
Regular exercise improves cardiovascular health, builds muscle, and reduces inflammation, all of which are key to a lower biological age.
Diet Quality
A diet rich in antioxidants and anti-inflammatory foods (like fruits, vegetables, and healthy fats) combats cellular damage and aging.
Sleep Quality
Sleep is when your body performs critical repair functions. Consistent, high-quality sleep is essential for slowing the aging process.
Stress Levels
Chronic stress releases cortisol, a hormone that accelerates cellular aging. Managing stress is crucial for staying biologically young.
Smoking & Alcohol
Toxins from smoking and excessive alcohol cause widespread cellular damage, significantly increasing biological age.
Genetics
While you can't change your genes, a healthy lifestyle can positively influence how they are expressed (epigenetics) and impact your aging process.
How Accurate is This Calculator?
This calculator provides an educational estimate using an AI model trained on scientific research into the lifestyle factors that influence aging. The result is intended to be an informative guide to help you understand how your habits may be impacting your healthspan, not a medical diagnosis.
For the most accurate clinical assessment, advanced tests that measure epigenetic markers (like DNA methylation "clocks") are available through specialized clinics and healthcare providers. However, this tool serves as an excellent, accessible starting point for self-assessment and motivating positive change.
