If you’ve ever wondered whether you’re aging well, the answer may be hiding in numbers you can track right from home. While birthdays tell you your chronological age, health experts are increasingly focused on biomarkers—measurable indicators that provide insight into how your body is actually functioning. Researchers studying biological aging have found that physical performance, cardiovascular health, cognitive function, and metabolic markers can reveal far more about future health than the number of candles on your birthday cake.
The good news is that many of the most useful active-aging biomarkers don’t require expensive laboratory testing. In fact, several can be measured with a stopwatch, a home blood pressure monitor, or simple observations of your daily activities. By tracking these metrics over time, you can identify trends, spot potential concerns early, and have more informed conversations with your healthcare provider. Here are 10 active-aging biomarkers worth monitoring.
