What the World’s Happiest Countries Tell Us About Living Better and Longer

Ever wondered how researchers measure happiness for entire countries? It might surprise you. The World Happiness Report asks people to rate their own lives on a scale from 0 to 10, then looks at trends in things like income, social support, health, freedom, generosity, and trust in government. The result is the “Happiness Index”—basically a snapshot of how content nations are feeling right now.


Happiest countries mapped

Between these two maps created by Vivid Maps, here's what you’ll notice: global happiness crept up from about 5.39 in 2015 to roughly 5.52 today. It may not seem like a huge jump, but across billions, that’s a meaningful lift.

Who’s Sitting Pretty—and Who’s Struggling?

Stable democracies with strong social systems tend to lead the rankings. Finland, Denmark, Iceland, Sweden, and the Netherlands score highest—Finland even wears the crown at around 7.7 out of 10. These places share a few key things: they trust each other and their institutions, have social safety nets, and give people freedom to shape their lives.

At the other extreme, Afghanistan, Lebanon, DR Congo, Sierra Leone, and Lesotho report much lower scores, ranging from about 1.7 to 3.3. Ongoing conflict, economic struggle, and weak institutions take a heavy toll on everyday life.

Does Feeling Happier Help You Live Longer?

Yes, it seems so. Studies show that people with higher life satisfaction often enjoy better health outcomes and live longer. In Singapore, for instance, researchers followed older adults for around 11 years and found that those who reported being happier had roughly a 15% reduced risk of death, even when accounting for age, income, and existing health. Larger reviews support the same pattern: happier people tend to be healthier and live longer.

As a result happiness and longevity often coexist in the same countries, places like Finland, Switzerland, Canada, New Zealand, and Japan. These are societies with good social cohesion, trust, and free systems.

Easy Ways to Add More Joy and Health to Your Day

Here are five everyday habits that feel good and support long-term health:

  • Stay connected. Whether it’s chatting over coffee or having a phone call with a friend, social ties really matter.
  • Move regularly. A short daily walk or some light exercise boosts mood and vitality.
  • Practice gratitude or mindfulness. Taking a few quiet moments to reflect can help calm stress.
  • Give back. Volunteering or small acts of kindness lift spirits—for you and others.
  • Keep learning. Reading, puzzles, picking up new skills—mental engagement matters for well-being.

Also, when you live in places or communities with low corruption and good public trust, that stability supports both happiness and health.

How Long Does Plastic Take to Decompose?

  Plastic: the unwelcome house guest at nearly every corner of our lives — from shopping bags to footwear, coffee cups to car parts. And yet, discarded, plastic doesn't just evaporate into thin air. No, it lingers. For decades. Even centuries. According to statistics presented by Visual Capitalist , plastic daily consumer goods can break down between 20 and 600 years, depending on the composition used, how they were created, and natural elements like water and sunlight they are exposed to. Let's go deeper into why plastic takes so long to break down — and what horrid messes it leaves behind in the process. Why Plastic Isn't "Natural" — and Why That's a Problem Plastic does not naturally exist. It's a product made from petroleum and natural gas. Its long, tough carbon bonds differ from anything naturally found in ecosystems, making it extremely resistant to microbial breakdown. When we toss a plastic bottle or bag away, it's not a matter of if it will s...

Moose population in North America

The moose ( Alces alces ) is the largest member of the deer family, characterized by its massive size, long legs, and distinctive broad, palmate antlers found in males. They have a dark brown or black coat and a humped shoulder. Moose are primarily found in the boreal and mixed deciduous forests of North America, Europe, and Asia. They are solitary animals, often found near bodies of water, and are herbivores that feed on leaves, bark, twigs, and aquatic vegetation. Despite their size, moose are strong swimmers and can run up to 35 miles per hour. The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North Americ...
