The Healthiest Countries in the World in 2026

Discover the Top Destinations for a Healthier and Happier Life

Moving abroad is always exciting, but relocating to one of the healthiest countries in the world can bring even greater benefits to your quality of life. If you’re considering moving for health-related reasons, it’s important to take a holistic view, looking beyond just access to healthcare.

For some, this might mean enjoying a healthier work-life balance in one of the world’s happiest nations. For others, it could be about access to a nutritious Mediterranean diet, affordable healthcare, or clean air – all of which contribute to overall well-being. To inspire your next move, this article highlights the world’s top destinations for expats in search of well-being and happiness in 2026 and beyond.

What Makes a Country “Healthy”?

What defines the healthiest countries in the world? While it’s easy to focus solely on healthcare systems, a truly healthy country is shaped by many interconnected factors.

This can range from government policies and environmental conditions to economic stability and even a nation’s overall happiness.

Key Factors Defining Healthiest Countries

Here are some of the key elements we considered when evaluating the world’s healthiest nations:

• Nutrition: Diet plays a significant role in overall health. For instance, the Mediterranean diet is often considered the world’s healthiest due to its emphasis on fresh, whole foods, healthy fats, and limited processed ingredients.
• Air Quality: Poor air quality can significantly impact daily life and contribute to chronic health issues, such as asthma and allergies. The Air Quality Index (AQI) is a valuable benchmark for comparing pollution levels worldwide.
• Water Quality: Reliable access to clean drinking water is essential to public health.
• Mental Health & Happiness: A positive outlook and general happiness are important to overall health. The World Happiness Report ranks nations based on factors such as social support, freedom, and life satisfaction, all of which are closely tied to mental well-being.
• Work-life Balance: Having enough personal time allows people to rest, build social connections, and pursue personal interests, which supports better physical and emotional health.
• Life Expectancy: Higher life expectancy often reflects strong public health infrastructure, access to care, and healthy lifestyles.
• Healthcare Infrastructure: The availability, affordability, and quality of medical services are fundamental to a nation’s health.
• Government Policies: Healthy countries often implement proactive public health policies, such as promoting vaccinations, encouraging nutritious diets, and regulating harmful substances, that help reduce health risks and support long-term well-being.
• Education: The world’s healthiest countries often have solid education systems that emphasize health from a young age, including nutrition, exercise, and mental well-being.
• Socioeconomics: Wealthier nations often have more resources to invest in health, such as clean infrastructure, public healthcare, and education; however, inequality within a country can also impact outcomes.

Key Differences Between the Healthiest and Unhealthiest Countries

According to the 2025 Bloomberg Global Health Index, the healthiest countries tend to have high levels of development, strong healthcare systems, and widespread economic stability.

In contrast, the world’s unhealthiest countries often face challenges like polluted air and water, malnutrition, limited access to care, lower life expectancy, and higher infant mortality.

However, even some highly developed countries struggle with issues like obesity, sedentary lifestyles, substance abuse, and mental health challenges, which can negatively impact overall public health.

How We Identified the Healthiest Countries in the World

In addition to the factors outlined above, we analyzed several independent global surveys and calculated average rankings across them.

We then combined this data with our expertise in international health insurance to compile our list of the healthiest countries in the world.

Below is an overview of the key sources we used:

2025 Bloomberg Global Health Index

This survey ranks the healthiest countries in the world using data from reputable sources, including the World Health Organization (WHO) and the World Bank.

It evaluates three main factors: life expectancy, environmental conditions (such as air pollution and water quality), and health risks (including obesity rates).

CEOWorld Global Health Index 2025

Conducted by a leading business magazine, this index ranks the world’s healthiest countries based on 10 key factors, providing a comprehensive overview of national health.

These factors include life expectancy, blood pressure, glucose levels, obesity, depression, happiness, alcohol use, tobacco use, physical inactivity, and government healthcare spending.

United Nations Human Development Report 2025

While this report focuses broadly on the quality of life in each country, it provides valuable insights into national health rankings.

It considers factors such as life expectancy, expected years of schooling, and gross national income per capita.

World Happiness Report 2025

This annual report ranks countries based on how happy citizens believe they are, using a single question from the Gallup World Poll.

The researchers then assess these alongside factors such as social support, freedom, generosity, and corruption using open-access data.

OECD Better Life Index

This well-respected index ranks OECD countries based on their performance across 11 factors deemed essential to the quality of life.

These factors include housing, income, community, education, environment, health, and work-life balance, providing a comprehensive snapshot of life in each country.

The Top 10 Healthiest Countries in the World in 2026

Based on the most recent available data, the following countries are leading the way in health, happiness, and overall quality of life in 2026.

Spain

Spain consistently ranks among the healthiest countries in the world – and it’s easy to see why.

Its robust healthcare system provides citizens with high-quality, affordable medical care, while Spanish cuisine centers on the Mediterranean diet, which is considered one of the healthiest in the world.

Residents also tend to stay active, enjoying outdoor activities and playing football, contributing to a life expectancy of around 84 years in 2025.

Additionally, socializing and maintaining a healthy work-life balance are key aspects of Spanish life.

Italy

Another of the healthiest countries in the world, Italy boasts a ranking of 91.59 on the 2025 Bloomberg Global Health Index.

Italians typically follow a predominantly Mediterranean diet, have access to a robust healthcare system, and spend plenty of time outdoors.

The country’s environment is also favorable, with good air quality and clean drinking water.

Additionally, Italians prioritize work-life balance, often taking time to socialize over long lunches and enjoy quality moments with family and friends.

Iceland

Ranked third in the 2025 Bloomberg Global Health Index with a score of 91.44, Iceland is one of the purest places on earth.

Its pristine air and water quality are among the best in the world, and residents stay active through outdoor activities in the country’s breathtaking landscapes.

Iceland also benefits from a wealthy economy and a robust healthcare system, which contribute to an average life expectancy of 83 years.

Like Spain and Italy, Icelanders value work-life balance, making time to socialize and enjoy leisure activities with friends and family.

Additionally, the country ranks 3rd in the World Happiness Report, highlighting its strong social support, high quality of life, and overall well-being.

Japan

Japan is renowned for the longevity of its population, with an average life expectancy of 85 years.

The country fosters many healthy habits, from a family-centered culture to regular physical activity.

The Japanese diet is also exceptionally nutritious and rich in heart-healthy fish and vegetables.

Additionally, Japan is one of the wealthiest countries and boasts one of the world’s best healthcare systems, offering high-quality, universal coverage.

Switzerland

It should come as no surprise that Switzerland is one of the healthiest countries in the world.

The country consistently performs well across all key factors and enjoys significant wealth, both at the government level and among its residents.

Switzerland is also a leader in healthcare, with a strong focus on preventative care that contributes to an average life expectancy of 84 years.

Its stunning natural environment encourages residents to stay active, with hiking, swimming, and walking being popular pastimes.

Additionally, the World Happiness Report ranks Switzerland as the 13th happiest country, partly thanks to its strong work-life balance.

Sweden

Sweden’s well-funded universal healthcare system ensures all residents can access high-quality care. As a result, the average life expectancy in this Nordic country is 83 years.

This is partly due to the country’s active outdoor lifestyle, with hiking, swimming, and the famous Swedish sauna culture being popular pastimes.

Many residents also follow a healthy diet that focuses on fresh fruits, vegetables, meats, and fish.

Additionally, the Swedish government invests heavily in public mental health services, which contributes to its ranking as one of the world’s happiest countries.

The nation’s strong policies that protect air and water quality also have a positive impact on public health.

Australia

Australia is the highest-ranking country in the Asia-Pacific region and has all the elements necessary to be one of the healthiest countries in the world.

Australian culture promotes outdoor activities such as surfing, swimming, and sports like cricket and rugby.

The country’s agricultural industry also ensures a steady supply of fresh, high-quality meats, fish, fruits, and vegetables.

Australians place a strong emphasis on work-life balance, and the government supports public health through initiatives such as anti-smoking campaigns and vaccination programs.

Additionally, residents have access to affordable universal healthcare.

Singapore

Singapore stands as a shining example of success in promoting well-being.

This success is rooted in a robust education system that instills healthy eating and exercise habits in children, alongside the country’s strong economic prosperity and a world-class universal healthcare system.

The government has implemented various initiatives, including compulsory vaccinations and preventive testing.

It has also invested in a network of community sports centers and gyms to make it easier for residents to stay active and maintain their health.

Many Singaporeans also benefit from regular physical activity through the extensive use of public transport.

Norway

Norway has many qualities that make it a strong contender for the title of the healthiest country in the world.

It ranks 7th in the World Happiness Report, reflecting its high levels of mental health and overall well-being.

The average life expectancy is 83 years, thanks to above-average health expenditure and a strong healthcare system.

Norway also performs exceptionally well in air quality rankings – its capital, Oslo, is often cited as the “greenest city” in Europe.

Add to that a population that embraces walking, cycling, and a diet rich in fresh, healthy ingredients, and it’s easy to see why Norway stands out as one of the world’s healthiest places to live.

Finland

Finland is another country that stands out as one of the healthiest in the world. It excels in every aspect, from healthcare to lifestyle, making it a model for overall well-being.

It boasts a strong, well-funded healthcare system, abundant green space, access to quality food, and a national preference for outdoor activity.

Finland also continues to lead the rankings in happiness. According to the World Happiness Report, it is the happiest country for the eighth consecutive year.

With excellent air quality and substantial investment in health education, Finland is a well-rounded model of national well-being.

Top Health Insights from the 2025 Rankings

With climate change, shifting geopolitics, and evolving societal preferences, the list of the healthiest countries in the world sees some movement each year.

Of course, Scandinavian nations, along with countries like Japan and Switzerland, consistently rank at the top, but even within the top 10, rankings can shift due to changing global factors.

Key Factors Driving Changes in the Latest Rankings

One of the key factors influencing the latest rankings is air quality. Several countries, including Italy, Spain, Canada, and Singapore, experienced a decline in their rankings due to significant drops in air quality.

On the other hand, countries like Norway and Finland experienced improvements in their overall rankings, thanks to enhanced air quality and extensive green spaces.

According to the most recent World Air Quality Report, only seven countries met the safe air quality guidelines: Australia, Estonia, Finland, Grenada, Iceland, Mauritius, and New Zealand.

Puerto Rico, Bermuda, and French Polynesia also fell within acceptable levels, while countries like Bangladesh, Pakistan, India, Tajikistan, Burkina Faso, and Canada were among those with some of the most polluted cities in the world.

The World Happiness Report 2025 also saw some shifts in rankings. Afghanistan experienced the most significant drop in happiness since 2012, with its change score nearly double that of Lebanon.

Countries such as Zimbabwe, Venezuela, Sierra Leone, Liberia, Lesotho, and the Democratic Republic of the Congo also experienced significant declines.

Conversely, nations such as Serbia, Bulgaria, Romania, Kosovo, Lithuania, Togo, Bosnia and Herzegovina, Georgia, and Armenia experienced notable improvements.

However, the Northern European countries of Finland, Denmark, Iceland, Sweden, and the Netherlands continue to dominate the top of the happiness rankings.

The Role of Lifestyle Factors and Health Risk Determinants

Lifestyle factors play a crucial role in influencing a country’s health rankings. For instance, despite consistently ranking as one of the healthiest and happiest countries, Finland has seen some shifts in its position.

This is due to several factors, such as higher rates of alcohol and tobacco use, a less-than-ideal diet, and higher levels of obesity.

While Finland’s overall health and happiness scores remain impressive, these lifestyle factors contribute to fluctuations in its rankings.

How Does the US Compare?

While the U.S. doesn’t rank among the top in any of the rankings used to determine the healthiest countries in the world, it performs relatively well compared to many other nations.

According to the 2025 Bloomberg Global Health Index, the U.S. scored 73.02, placing it 34th. Additionally, the Legatum Prosperity Index ranks the U.S. 19th, behind countries like Denmark, Switzerland, Germany, New Zealand, Japan, and Singapore.

This lower rank is primarily due to weak scores in healthcare, which is the most expensive in the world, as well as concerns about safety and security. Similarly, the World Happiness Report 2025 places the U.S. 24th, behind the U.K., Germany, the UAE, Canada, Israel, and most of Northern Europe.

The OECD Better Life Index also highlights that Americans tend to have less work-life balance compared to the global average, which can limit time for socializing, exercising, and eating well.

Additionally, issues such as late public spending on child welfare and education, as well as the lack of parental leave, place extra stress on families.

Eating habits are another factor affecting the U.S.’s lower rankings. Americans generally consume larger portions of food rich in salt and sugar, and they prefer ultra-processed foods over fresh, whole ingredients.

As a result of these factors, many expats who move to countries that rank higher, such as Australia or Switzerland, report greater satisfaction.

They often feel they have better access to healthcare and education, improved work-life balance, and superior childcare options.

The Unhealthiest Countries in the World

While it’s hard to single out the unhealthiest country in the world, there are a few that may qualify. Certain nations consistently rank at the bottom of health, happiness, and safety indexes.

Many of these countries, particularly those in sub-Saharan Africa, face significant challenges in these areas, which contribute to their low rankings in overall well-being.

The Legatum Prosperity Index tracks twelve composite categories, including health. It also considers factors such as safety and security, personal freedom, governance, social capital, investment environment, living conditions, access to health, education, and environmental sustainability.

Based on the Index, the following countries are among the least prosperous – and in this case, the most unhealthy – countries in the world:

• South Sudan
• Yemen
• Central African Republic
• Afghanistan
• Somalia
• Chad
• Democratic Republic of Congo
• Eritrea
• Syria
• Burundi

Protect Your Well-Being Wherever You Go

Living in one of the healthiest countries in the world naturally makes it easier to prioritize your well-being. These nations offer nutritious food, strong healthcare systems, clean environments, and a good work-life balance, making them ideal for a healthy lifestyle.

Whether you’re drawn to the Scandinavian countries, the Mediterranean way of life, or the peaceful landscapes of Iceland, each of these top-ranking nations offers something unique when it comes to health and happiness.

However, no matter where you choose to relocate, securing international health insurance is essential. It ensures access to quality healthcare and provides peace of mind.

In addition to health coverage, it’s essential to research the country’s healthcare system, work-life balance, diet, air quality, and overall quality of life, all of which are crucial to a fulfilling life abroad.

While living in a healthy country makes maintaining well-being easier, your personal choices – such as eating a balanced diet, avoiding pollution, and prioritizing mental health – remain essential.

So, whether you’re considering the fresh air of Finland, the outdoor lifestyle of Australia, or the robust healthcare system of Japan, be sure to plan. Conducting thorough research and securing comprehensive medical insurance will provide you with the peace of mind you need to thrive.

After all, a healthy move is the happiest move. Ensure you’re covered and ready to embark on a fulfilling life wherever you go.
