Want to Know How You Age? It’s All in Your Hormones

Ageing. It’s a word that carries different meanings for different people. For some, it’s a graceful journey filled with wisdom and self-discovery. For others, it’s an unwelcome reminder that time waits for no one. But what if I told you that ageing isn’t just about counting the candles on your birthday cake? Science is now telling us there’s another clock ticking inside us—a biological clock that could be running ahead of, or behind, our chronological age.

Researchers at Osaka University have uncovered a new way to determine our biological age—the age at which our body truly functions—using the steroid hormones flowing through our bloodstream. Their groundbreaking study, published in Science Advances, takes us one step closer to understanding the true nature of ageing. By analyzing steroid hormones in our blood (and identifying patterns that correlate with different rates of aging with the help of AI), researchers have identified a way to measure our biological age—how fast or slow our body is actually ageing. And let me tell you, the results are both fascinating and sobering.

The findings challenge long-held beliefs about aging, revealing that it’s not just genetics or lifestyle but a complex interplay of hormones that dictate how fast (or slow) our bodies truly age. Basically, hormones, as critical messengers in the body, hold valuable clues about the aging process, potentially revealing discrepancies between chronological age and biological health.

Stress Hormone, The Hidden Price of Ageing

The study highlights cortisol, our primary stress hormone, is a major player in biological ageing. The findings suggest that doubling cortisol levels can increase biological age by 1.5 times. That means those sleepless nights, endless deadlines, and constant worries are doing more than just making us feel exhausted—they’re accelerating our internal clock.

And ladies, we’re not off the hook. The research also points to other hormones, like 17α-hydroxyprogesterone and cortisone, as additional factors in ageing. Hormones are not just about mood swings and menopause—they are an essential part of how we age.

The Power of Knowledge

As an editor, I’ve read countless studies on ageing, but this one stands out. Not only does it redefine how we understand ageing, but it also gives us something incredibly valuable: knowledge. If we can measure ageing at a biological level, then we can potentially intervene. Imagine a future where a simple blood test could tell you if you’re ageing faster than you should—and, more importantly, give you the tools to slow it down.

Can We Turn Back Time?

This research leaves us with a powerful question: If ageing is largely dictated by our biology, can we manipulate it? Scientists are already looking at ways to regulate hormone levels through diet, stress management, and even potential medical interventions. And let’s not forget the basics—exercise, sleep, and mindfulness—all of which can influence hormone balance.

The truth is, we may not be able to stop the clock, but we can certainly slow its ticking. And perhaps, just perhaps, the best-kept secret to longevity isn’t found in an expensive cream or a trendy supplement, but in understanding and mastering the biological processes within us.

The Conversation We Need to Have

So, how much control do we really have over aging? Can lifestyle changes truly make a difference, or is science moving toward a future where medicine does the heavy lifting? If we can measure aging, can we ultimately master it?

Aging is no longer just about time—it’s about biology. And now that we have the science to prove it, it’s time to start rewriting the rules.
