Prevention, Longevity, Healthspan: How to Live Not Just Longer, but Healthier for Longer

At a glance

• Lifespan (how long you live) and healthspan (how long you live in good health) are not the same — globally there’s an average of about 9.6 years between them.
• A large share of the years lived with poor health is caused by chronic diseases that often develop silently over many years but are most effectively addressed when detected early.
• Knowing your baseline health allows you to take targeted action. A structured assessment of your key health markers provides clarity and creates the foundation for effective prevention.

Imagine two people, both 84 years old. One still enjoys hiking, cooks independently and plays with their grandchildren. The other has spent the past twelve years living with multiple chronic conditions, taking medication and coping with significant health limitations. They have lived equally long—but not equally well.

This difference lies at the heart of longevity. It’s not about adding as many years as possible to your life, but about adding as many healthy years as possible. In this article, we’ll explain what healthspan means, why the gap between healthspan and life expectancy is so large, and how prevention can help narrow that gap.

What does healthspan mean — and how does it differ from life expectancy?

Healthspan refers to the years of your life that you spend healthy, active and largely free from disease-related limitations. Life expectancy (lifespan), by contrast, simply measures how long you live, regardless of your health during those years.

The difference between the two is known as the healthspan gap—the years we spend living with illness or reduced health. A large analysis covering 183 countries estimates this gap at an average of 9.6 years worldwide, and it continues to grow. In other words, we are gaining years of life faster than we are gaining healthy years.

How large is the healthspan gap in Switzerland?

Switzerland has one of the highest life expectancies in the world: 84.2 years in 2024 (85.9 years for women and 82.4 years for men).

Healthy life expectancy, however, is considerably lower—at around 71 years.

In practical terms, this means that the average person in Switzerland spends around 13 years of life in reduced health. Rather than being a discouraging statistic, this represents a significant opportunity. The key question is not only “How long will I live?” but also “How many of those years will I spend in good health?”—and that is something we can actively influence.

What is longevity really about?

Longevity is not about living forever. It's about living as long as possible in good health, with illness occurring as late as possible and lasting for as short a time as possible. This concept is known as compression of morbidity and has been a cornerstone of preventive medicine for decades.

It shifts the focus from simply adding years to life toward adding healthy years to life. Seen this way, longevity is no longer about expensive anti-ageing promises or the latest miracle treatment. Instead, it is about something far more practical—and far more effective: identifying the most important health risks early, while there is still time to influence them.

What determines your healthspan — and what can you influence?

A large part of your healthspan is shaped by factors you can influence. The years spent in poorer health are mainly caused by non-communicable diseases—including cardiovascular disease, diabetes and cancer—which account for around three out of every four deaths worldwide.

Many of these conditions are driven by the same underlying risk factors:

• Cardiovascular and metabolic health (blood pressure, blood lipids, blood sugar)
• Body composition — especially muscle mass and visceral fat
• Movement and strength, nutrition, sleep and recovery
• Silent inflammation and nutrient status
• Not influenceable, but worth knowing: genetic factors (e.g. Lp(a))

The key point is that these risk factors often shift gradually and silently in an unhealthy direction. High blood pressure doesn't hurt, and rising long-term blood sugar usually causes no symptoms either.

That's why many of the factors that matter most can be measured years before you notice any signs or symptoms.

Why is prevention the strongest lever?

Because prevention has the greatest impact when it starts early.

Many chronic diseases and premature deaths can be prevented—or at least delayed—through early detection and timely action.

Timing matters. Mildly elevated values often leave plenty of room for meaningful improvement through targeted lifestyle changes or medical intervention. Once a disease has become established, that opportunity is usually much smaller.

Prevention isn't about distrusting your body—it's about taking good care of it. It means checking in regularly, recognising important changes early and responding before problems develop.

Instead of thinking, "One day it will probably happen to me," prevention gives you clarity:

"I know where I stand—and I know what I can do next."

Why you can’t improve what you don’t measure

You can only improve your healthspan if you understand your starting point.

A single health marker isn’t enough. Health is shaped by the interaction of many different factors. Only by looking at the complete picture—including cardiovascular health, metabolism, organ function, body composition and nutrient status—can you gain a true understanding of your health.

That’s why any meaningful longevity strategy starts with a comprehensive health assessment: a thorough evaluation of your key biomarkers, interpreted by a physician and used as a baseline for your future health journey.

In separate articles, we explain how a comprehensive Full Body-Check-up is structured and why relying on a single biomarker doesn’t provide an accurate picture of your health.

One important point: measuring alone doesn’t change anything. Individual results only become meaningful when they’re interpreted in context. Medical expertise transforms isolated numbers into a clear understanding of your health—and turns knowledge into meaningful action.

What can you do for your healthspan?

The most effective levers are unspectacular — and that’s exactly why they’re reliable:

• Movement and strength. Regular activity and preserving muscle mass are among the best-evidenced factors for healthy ageing. Muscle isn’t aesthetics; it’s metabolic and fall protection in later life.
• Nutrition. Focus on mostly unprocessed foods, adequate protein intake and plenty of plant-based foods. The goal isn’t strict dietary rules but sustainable habits you can maintain over the long term.
• Prioritise sleep and recovery. Chronic sleep deprivation and ongoing stress have a negative impact on cardiovascular health, metabolism and the immune system.
• Know your risks early. Measure your blood pressure, blood lipids, blood sugar and—at least once in your lifetime—your Lp(a) level. It’s far better to measure than to guess.
• Consistency over perfection. Small, steady steps beat short radical programmes. Healthspan is a long-distance run, not a sprint.

You don’t need expensive longevity programmes, miracle treatments or relentless self-optimisation to support healthy ageing. The most effective foundations are surprisingly straightforward.

How does care support your healthspan?

care is built as a preventive health platform designed precisely for this long haul — from measurement to action:

• Build a comprehensive health baseline: a broad Full Body Check-up (133 biomarkers), carried out at a partner lab and reviewed by FMH doctors.
• Understand, not just numbers: results clearly presented in the App, with interpretation and concrete recommendations.
• Move into action: receive tailored recommendations on lifestyle, nutrition and targeted follow-up testing based on your individual health profile, rather than a one-size-fits-all approach.
• Track over time: observe values over the course of time and adjust, instead of collecting snapshots.

That turns an abstract goal (“ageing healthily”) into a concrete, repeatable cycle of measuring, understanding and acting.

Take the first step towards more healthy years. Healthspan starts with clarity about your values. A Full Body Check-up is the cleanest starting point: measured broadly, reviewed by FMH doctors, with clear next steps. → Book your Full Body Check-up

The bottom line

Longevity isn't about adding more years to your life—it's about adding more life to your years.

In Switzerland, there's a gap of around 13 years between life expectancy and healthy life expectancy. That's where prevention has the greatest opportunity to make a difference.

The approach isn't complicated: understand your biggest health risks early, establish a reliable baseline and stay consistent over time.

Prevention is the most effective and sustainable way to not only live longer, but to stay healthier for longer.

Frequently asked questions

What’s the difference between lifespan and healthspan?

Lifespan is life expectancy — how long you live. Healthspan is the years you spend in good, active health. The goal of prevention is to bring healthspan as close as possible to life expectancy.

Can healthspan really be influenced?

To a large extent, yes. Many years spent in poor health are caused by chronic diseases with well-understood and often modifiable risk factors, including cardiovascular health, metabolic health, physical activity, nutrition and sleep.

Identifying these risks early and taking targeted action can help preserve your health for longer and delay the onset of disease.

Does longevity mean expensive anti-ageing products?

No. The best-evidenced levers are unspectacular: movement and strength, good nutrition, sleep, and knowing your own risk values early. No miracle products required.

Where’s the best place to start?

Start by establishing a comprehensive baseline of your key health markers through a physician-reviewed health assessment. This provides personalised next steps tailored to your individual health profile instead of relying on trial and error.

From what age should I care about healthspan?

The earlier, the better. Many health risks begin to develop silently during mid-adulthood. Establishing an early baseline gives you a valuable reference point for monitoring your health in the years ahead.
