There is a number worth pausing on: 84. That is the average life expectancy in Spain — among the highest in Europe and, according to The Lancet, forecast to become the highest in the world by 2040. It is not an accident or luck, but the cumulative result of a culture, a climate, a cuisine, and a way of living that the rest of the world has spent decades trying to understand and replicate.
The OECD's 2025 Health at a Glance report ranks Spain third globally for life expectancy, behind only Switzerland and Japan. Spaniards live, on average, almost three years longer than the OECD norm and more than two years longer than the EU average. The country also outperforms most of Europe on preventable mortality, with a rate of 92 per 100,000 inhabitants compared to an OECD average of 145.
So what is Spain actually doing right?
The diet that science keeps confirming
The Mediterranean diet has been studied more extensively than almost any other dietary pattern on earth. And every time researchers look, they find the same thing: it works.
The landmark PREDIMED study — one of the most rigorous dietary trials ever conducted — followed thousands of Spanish adults at high cardiovascular risk for nearly five years. Those who ate a Mediterranean diet supplemented with extra virgin olive oil had significantly fewer major cardiovascular events than those on a low-fat diet. The study's authors concluded that the benefits could not be attributed to any single ingredient, but that extra virgin olive oil was the most powerful individual factor.
And Spain is, by a wide margin, the world's largest producer of olive oil.
Spaniards consume somewhere between 10 and 13 litres of olive oil per person per year, depending on the source and the year. The UK and US manage roughly one litre. This is not a minor dietary footnote. Researchers have linked higher daily intake of extra virgin olive oil to lower cardiovascular risk and lower all-cause mortality. Spain's daily cooking habits, in other words, function as a form of preventive medicine.
Beyond olive oil, the Spanish diet is built around fresh vegetables, fruit, fish, legumes, nuts, and whole grains, with red meat playing a supporting rather than starring role.
UNESCO recognised the Mediterranean diet as an Intangible Heritage of Humanity in 2013 — one of very few dietary traditions to receive that designation.
Movement built into daily life
One of the more underappreciated facts in the Spanish health story is how much physical activity is embedded in ordinary routines. According to OECD data, only 25% of adults in Spain fail to meet recommended levels of physical activity — significantly better than the OECD average of 30%.
This matters more than it might seem. Regular movement — not intense exercise, just consistent daily activity — is associated with lower rates of heart disease, type 2 diabetes, depression, and cognitive decline. Spain does not need gym culture to be active. The activity is woven into daily life: walking to the market, strolling before dinner, the afternoon paseo. Movement is social, not medicinal.
Add to this the country's investment in cycling infrastructure, public parks, and green spaces throughout its cities, and you have a population that is routinely, almost incidentally, keeping itself well.
Healthcare that reaches everyone
Spain operates a universal public healthcare system, funded through taxes and available to all residents. The system places a strong emphasis on preventive care and early intervention — and the results show. Spain's preventable mortality rate is 92 per 100,000 inhabitants, well below the OECD average of 145. Treatable mortality, at 50 per 100,000, is similarly low.
The 2025 OECD/European Commission Country Health Profile confirms that Spain remains among Europe's top performers for access to care and population health outcomes. The country also recorded one of the lowest rates of unmet medical needs in the EU, at just 1.7%, compared to the OECD average of 3.4%.
The social cure
There is a dimension to Spanish health that does not appear in dietary guidelines or health indices, but that researchers increasingly believe is central to longevity: the quality of social connection.
Spain is a country built around communal life. Meals are shared, long, and frequent. The terrace café — the terraza — is not a luxury but a daily institution. Festivals, neighbourhood gatherings, family dinners: these are not occasional events but the fabric of ordinary life.
The science behind this is robust. Social isolation has been identified by major public health bodies, including the WHO, as a serious risk factor for early death and chronic disease. Spain's culture of togetherness — the unhurried meal, the evening paseo, the multi-generational table — is, in effect, a form of health infrastructure.
Then there is Marbella
If Spain is one of the healthiest environments on earth, Marbella is one of its most concentrated expressions.
Sitting on the Costa del Sol in Andalucía — the sunniest region of one of the sunniest countries in Europe — Marbella receives around 320 days of sunshine per year and roughly 2,900 hours of annual sunlight. For context, London receives about 1,633 hours. The Spanish weather service has repeatedly highlighted Málaga, Marbella's nearest city, as one of the best climates in Spain to live in.
This matters physically, not just aesthetically. Sunlight is the primary source of vitamin D, which plays a role in bone density, immune function, mood regulation, and the prevention of certain cancers. Populations in northern Europe, where sunlight is scarce for months at a time, show consistently higher rates of vitamin D deficiency. In Marbella, that deficiency is genuinely rare.
Marbella's microclimate is shaped by two geographical facts: the Mediterranean Sea to the south and the Sierra Blanca mountain range to the north. The mountains block cold winds from the interior; the sea acts as a natural thermostat, keeping summers bearable and winters mild. Average daytime temperatures in January sit at 16–18°C. The sea itself remains warm enough for swimming well into autumn.
The practical consequence is an outdoor life that does not pause for seasons. Golf, hiking, swimming, cycling, walking along the promenade — these are year-round activities in Marbella, not summer luxuries. Outdoor living, combined with the social culture of Andalucía and the Mediterranean diet available in every restaurant and market, creates conditions for health that are difficult to replicate elsewhere.
A few numbers worth keeping
- Spain's life expectancy: 84 years (3rd highest in the OECD, behind Switzerland and Japan)
- Forecast life expectancy by 2040: 85.8 years — projected to be the highest in the world (The Lancet)
- Preventable mortality rate: 92 per 100,000 — well below the OECD average of 145
- Marbella annual sunshine: ~2,900 hours / 320 days
- Olive oil consumption in Spain: 10–13 litres per person per year (vs. ~1 litre in the UK and US)
- Healthcare coverage: universal, with one of the lowest unmet-need rates in the EU
Why this matters if you are thinking about where to live
People move to Marbella for many reasons — the beauty, the culture, the community, the weather. But the health dimension deserves more attention than it typically receives in conversations about where to put down roots.
The factors that make Spain one of the healthiest countries in the world are not exotic or expensive. They are diet, movement, sunlight, community, and access to good care. Marbella happens to offer all of them in unusual abundance, concentrated into a place where outdoor life is not an aspiration but simply what happens when you open the front door.
That is not a small thing.
Marbella Club Hills is a residential development set in the hills above Marbella, Andalucía, designed for those who want to live well — in every sense of the phrase.
