In an increasingly chaotic world, health has become the ultimate luxury—and priority. As we navigate 2025, the definition of a healthy country has grown more complex, encompassing not just long life expectancy or excellent hospitals, but also mental well-being, environmental health, diet, public health infrastructure, and community trust. Here’s a look into the healthiest countries in the world right now, backed by recent global indexes, scientific research, and health data.
Top Healthiest Countries in 2025
According to a blend of sources like the Bloomberg Global Health Index, CEOWORLD Health Index, Global Health Security Index (GHSI), WHO datasets, and academic research, these countries rank consistently at the top:
1. Spain
Spain retains its spot as one of the healthiest nations, boasting one of the highest life expectancies globally (86 years for women and 81 for men). What makes Spain shine? A relaxed lifestyle, a high-functioning universal healthcare system, and the celebrated Mediterranean diet rich in olive oil, seafood, legumes, and fresh vegetables.
Lesser-known fact: Spain has a siesta culture, not just for naps but for reducing afternoon stress levels. Though less practiced in big cities, this downtime habit is believed to contribute to lower hypertension rates in rural areas.
2. Italy
Like Spain, Italy benefits from the Mediterranean diet, strong family bonds, and a public healthcare system that covers almost all medical needs.
Lesser-known fact: Italians over 100 years old (centenarians) often cite community, light movement (like walking or gardening), and a spiritual outlook as secrets to their longevity—not just diet alone.
3. Iceland
Iceland punches well above its weight. With near-zero air pollution, a largely organic food supply, geothermal energy, and low population density, it offers a clean, balanced environment. Healthcare access is universal, and obesity rates are among the lowest in the West.
Lesser-known fact: Icelandic children grow up immersed in outdoor activities—even in winter—boosting immune systems and long-term health resilience.
4. Japan
Japan consistently ranks high in health thanks to cultural habits that include walking, moderate food portions, low red meat intake, and social harmony.
Lesser-known fact: The concept of Hara Hachi Bu (eating until you’re 80% full) is taught from a young age. It helps control portion sizes and prevent overeating. Japanese public schools also offer some of the healthiest, chef-planned lunches in the world.
5. Finland & Norway
These Nordic neighbors lead the way in mental well-being, green urban planning, and access to high-quality healthcare. Finland, in particular, has been named the happiest country in the world for six years straight.
Lesser-known fact: Finland’s “baby box” program—where all expectant mothers receive a box of baby essentials from the government—has contributed to one of the lowest infant mortality rates worldwide.
6. Switzerland
This Alpine country scores high across all health metrics: clean air, safe water, world-class hospitals, and a strong public-private healthcare system. The Swiss also consume less processed food and emphasize outdoor recreation.
7. Singapore
Singapore’s health system is among the most efficient globally, with high health outcomes despite relatively low spending. With near-universal insurance and a strong emphasis on preventive medicine, it’s a model for urban health management.
Lesser-known fact: Singapore’s entire urban design—from shaded walkways to green roofs—is engineered to reduce heat stress and encourage walking, which helps tackle lifestyle diseases.
8. Taiwan
Taiwan has quietly become a healthcare superstar. Its National Health Insurance (NHI) system covers almost all citizens and residents, with extremely low out-of-pocket costs and short wait times.
Lesser-known fact: According to CEOWORLD’s 2025 report, Taiwan is ranked #1 in healthcare system efficiency, surpassing even Nordic countries.
9. Australia
Australia combines clean living with an outdoor culture that encourages fitness and mental well-being. Its universal healthcare system provides excellent access to care, and anti-smoking campaigns have significantly improved public health.
Lesser-known fact: Australia’s national health campaigns—such as its plain cigarette packaging law (Designed to reduce the appeal of smoking—especially among young people—it removes branding, colors, and promotional text, making all packs look uniform and unattractive.) —have become global models for preventive healthcare.
10. South Korea
South Korea boasts advanced medical infrastructure, strong public hygiene awareness, and one of the fastest-growing life expectancies globally. Preventive screenings are widely practiced, and digital health innovation is booming.
Lesser-known fact: South Korea has one of the world’s highest rates of regular health checkups, often subsidized by employers and the government, contributing to early detection and treatment.
What Defines a Healthy Country
In the past, health rankings leaned heavily on hospitals and disease statistics. Today, we know that broader systems and lifestyle factors matter just as much. Here are the pillars of a healthiest countries in the world:
1. Diet & Nutrition
Mediterranean countries enjoy heart-healthy fats, fresh produce, and community meals. In Japan, fermented foods and plant-based staples reduce inflammation and boost gut health.
Insight : Countries with lower sugar and red meat consumption consistently report fewer lifestyle-related diseases.
2. Environmental Quality
Clean air and water are non-negotiables. Nordic countries, Iceland, and Switzerland have some of the world’s lowest air pollution levels, leading to fewer respiratory and cardiovascular diseases.
3. Preventive Health Systems
Top-ranking countries don’t just treat illness—they prevent it. Mandatory vaccinations, free screening programs, and widespread public health campaigns create long-term savings and stronger communities.
4. Mental Health & Community
Loneliness is a major health risk. Finland’s happiness isn’t just due to money—it’s supported by social trust, strong education, and community initiatives that reduce isolation.
Interesting Insight: A Harvard study found that social connections are more predictive of long-term happiness than income or job success.
5. Physical Activity & Walkability
Healthiest countries prioritize movement in daily life. In Tokyo, walking and biking are integrated into every commute. In Copenhagen and Amsterdam, bike lanes outnumber car lanes.
Rising Stars in Global Health
A few countries are rapidly improving their health metrics and gaining global attention:
Portugal
Portugal now offers universal healthcare and emphasizes mental wellness policies. It has significantly reduced smoking rates and improved mental health services.
Costa Rica
Costa Rica has a healthcare system that provides nearly free care to citizens and ranks impressively for longevity. The Nicoya Peninsula is a certified “Blue Zone,” where people regularly live to 100.
New Zealand
With aggressive anti-smoking policies (including banning cigarette sales to those born after 2008), lush green environments, and Maori-influenced wellness philosophies, New Zealand is a health-conscious leader.
What Can Other Nations Learn?
From the world’s healthiest countries, we gain key takeaways:
- Invest in prevention. It’s cheaper and more effective than treating disease.
- Design cities for people, not just cars. Green space, walkability, and clean air go a long way.
- Focus on nutrition education. Teach healthy habits from a young age.
- Promote mental wellness. Happiness is inseparable from health.
