There's a statistic that tends to stop men in their tracks when they first hear it.
Men live, on average, four years less than women. In the UK, male life expectancy sits at around 79. For women, it's 83. That gap has narrowed over the decades — but it hasn't closed. And when you look at healthspan rather than lifespan, the picture becomes more striking. Men spend a higher proportion of their later years in poor health than women do.
This isn't bad luck. And it isn't simply because men are less likely to see a doctor — though that's part of the story. It's biology. Specifically, it's the way inflammation, hormones, and cardiovascular risk follow a different timeline in men.
The inflammation difference
Chronic inflammation is increasingly understood as one of the primary engines of ageing. It sits at the root of cardiovascular disease, cognitive decline, metabolic dysfunction, and cancer — the four leading causes of premature death in men.
Women, broadly speaking, have a biological advantage here. Oestrogen appears to have anti-inflammatory properties, which is one reason pre-menopausal women tend to have lower levels of systemic inflammation than men of the same age. After menopause, that advantage narrows — which is also when women's rates of cardiovascular disease begin to converge with men's.
For men, the inflammatory trajectory is steeper and starts earlier. By their 30s, many men are already accumulating the kind of low-grade, chronic inflammation that doesn't show up as pain or obvious symptoms — but is quietly eroding arterial health, immune function, and cellular repair capacity at the same time.
This is called inflammaging — the slow, systemic inflammation that drives biological ageing at the cellular level. It's not dramatic. It's incremental. And that's precisely what makes it easy to ignore until the consequences become harder to.
The inflammation x testosterone connection
From around age 30, testosterone begins to decline in men — typically at a rate of around one percent per year, accelerating in the 40s and 50s. Most men attribute the effects to simply getting older: less energy, slower recovery, subtle changes in mood and motivation, increasing difficulty maintaining muscle mass.
What's less widely understood is how closely this hormonal shift is linked to inflammation. As testosterone falls, systemic inflammation tends to rise — and rising inflammation, in turn, suppresses testosterone production further. It's a feedback loop, and without something to interrupt it, it tends to compound over time.
Testosterone plays a broader role than most people realise. It supports muscle synthesis, metabolic regulation, cardiovascular health, and cognitive function. Its decline isn't just about how capable you feel in the gym. It's about how your body maintains the systems that determine how well you age.
The earlier men understand and address this hormonal trajectory, the more they can do to change it. Resistance training, sleep quality, anti-inflammatory nutrition, and targeted supplementation have all been studied for their role in supporting healthy testosterone levels and breaking the inflammation loop.
The behaviours accelerating the biology
Biology isn't the whole story. Men are statistically less likely to attend routine health screenings, less likely to seek medical advice for symptoms, and — in the UK — significantly less likely to be diagnosed with conditions like depression, anxiety, and chronic pain until they've progressed further than they would in women.
This has real consequences. Earlier detection of cardiovascular risk, earlier intervention on inflammatory markers, earlier conversations about hormonal health — all of them change outcomes substantially.
Men's Health Week exists partly because awareness is intervention. Knowing that your cardiovascular risk increases meaningfully from your 30s onwards — and that VO2 max, resting heart rate, and inflammatory markers are measurable, actionable data points — changes what you decide to do next.
It's worth noting that the four-year longevity gap is not fixed. In populations where men engage more actively with preventive health, the gap narrows. In Blue Zone communities — where longevity outliers cluster — men and women live in closer proximity to each other's healthspan than the national average would predict.
What actually moves the needle
The interventions with the most evidence behind them for male longevity aren't complex. They tend to be consistent application of the fundamentals, at a level that's sustainable over years rather than weeks.
- Resistance training is the most robustly evidenced intervention for maintaining muscle mass, metabolic health, and testosterone levels as men age. Two to three sessions a week produces measurable differences in inflammatory markers and metabolic function.
- Sleep is where a significant amount of testosterone production and cellular repair happens. Consistently poor sleep quality — six hours or less — is associated with accelerated hormonal decline and elevated inflammation.
- Anti-inflammatory nutrition doesn't require a radical overhaul. The evidence points to a modest set of consistent choices: omega-3-rich foods, polyphenol-dense vegetables and berries, reduced ultra-processed food intake, and adequate protein to support muscle protein synthesis.
- Targeted supplementation — where the formula is built around biological mechanisms rather than trending actives — can support the systems that diet and exercise alone don't fully address. Particularly for men navigating the compounding effects of hormonal change and inflammatory load in their 30s, 40s, and 50s.
The four-year gap is real. But it's not a verdict. It's a starting point — and for most men, the window to act on it meaningfully is earlier than they think.
