Understanding Your Biological Age vs. Chronological Age

What is Biological Age?

While your chronological age simply counts the years since you were born, your biological age tells a different story. It's a measure of how well your body is functioning compared to your actual age. Two people can be 45 chronologically, but one might have a biological age of 38, while the other is closer to 52.

Why Does Biological Age Matter?

Your biological age is a better predictor of health outcomes, disease risk, and longevity than chronological age. Research shows that people with a lower biological age tend to:

• Live longer, healthier lives
• Have lower risk of chronic diseases
• Maintain better physical and cognitive function
• Recover faster from illness and injury

How HealthLens Calculates Your Biological Age

HealthLens uses scientifically-validated metrics to calculate your biological age:

• Sleep Quality: Optimal range of 7-9 hours with deep sleep cycles
• Physical Activity: 8,000-12,000 steps daily and active calories
• Heart Rate: Resting heart rate between 50-70 bpm indicates good cardiovascular health
• Heart Rate Variability (HRV): 30-80ms shows strong recovery capacity
• Nutrition: Balanced calorie intake and meal quality

The Daily Age Delta

Every morning at 7 AM, HealthLens shows you your overnight age delta—the exact number of years you got younger or older based on yesterday's habits. This immediate feedback helps you understand which behaviors are keeping you young and which are accelerating aging.

Can You Reverse Your Biological Age?

The exciting answer is yes! Studies have shown that lifestyle changes can reduce biological age by several years. By optimizing sleep, staying active, managing stress, and eating well, you can literally turn back your biological clock.

HealthLens helps you track these changes in real-time, giving you the motivation and data to make lasting improvements.
