Living longer used to feel like the whole point. More birthdays, more time with people you love, more years to do the things that matter. But a new analysis1 tracking 204 countries over three decades is asking a harder question: are those extra years actually good ones?
Researchers found that while life expectancy has risen significantly around the world, more of those added years are being spent managing chronic illness, pain, or disability
It’s a shift that changes how we think about healthspan versus lifespan and what it actually means to age well
A 33-year look at how we’re actually aging
The Global Burden of Disease 2023 analysis tracked two numbers across 204 countries: how long people live, and how many of those years they actually spend in good health
Researchers followed both from 1990 to 2023, then compared them. That gap (the years spent sick, in pain, or managing a chronic condition) is what the study calls the “morbidity gap.”
It’s one of the most thorough health analyses ever done, pulling together three decades of data on deaths, diseases, and disabilities from around the world. The central question is as we’ve gotten better at keeping people alive, have we actually kept them healthy?
More years, but not healthier ones
In 1990, the average person worldwide spent about 8.8 years of their life in poor health. By 2023, that had climbed to 10.7 years, nearly two more years, a roughly 22% increase. Today, about 14.5% of the average person’s life is spent in poor health, up from 13.6% in 1990
And this wasn’t just happening in a handful of places. The morbidity gap grew in 203 out of 204 countries. It also didn’t just pile up at the end of life; it widened across adulthood
Interestingly, the countries with the longest life expectancies also had the largest gaps. More reut that doesn’t automatically mean they’re living better
The conditions driving the most unhealthy years
The conditions responsible for the most years lived in poor health aren’t heart attacks or cancer. They’re chronic, largely non-fatal conditions that accumulate quietly over decades
Low back pain is the single biggest contributor globally, followed by depression and anxiety, age-related hearing loss, falls, and a cluster of other long-term conditions like diabetes and chronic respiratory disease
Together, those five categories account for more than 57% of all unhealthy years worldwide. They won’t kill you, but they make life harder, and they tend to stick around

The risk factors you can actually change
The study also identified the modifiable risk factors most responsible for driving years lived in poor health
At the top are high fasting blood sugar (the amount of glucose in your blood after not eating for at least eight hours), high body mass index, tobacco use, and, particularly in lower-income countries, child and maternal malnutrition
High blood sugar and excess body weight are especially significant because they are among the leading contributors in high-income settings, where the burden is already the largest
Monitoring your metabolic bloodwork is one of the most direct ways to understand where you stand. Unlike age or genetics, blood sugar and body weight respond to lifestyle, and the research on what moves the needle is robust
How to protect the years ahead
- Move regularly: Physical activity is one of the most powerful tools for metabolic health, musculoskeletal resilience, and mental well-being, three of the top drivers of years lived in poor health. Strength training supports muscle mass and bone density as you age, while aerobic exercise helps regulate blood sugar and blood pressure.
- Prioritize a nutrient-dense diet: What you eat directly shapes your metabolic health. Diets built around whole foods, fiber, lean protein, and healthy fats support stable blood sugar and a healthy weight, two of the biggest modifiable levers identified in the study.
- Protect your sleep: Poor sleep is tightly linked to metabolic dysfunction, elevated blood sugar, weight gain, and mood disorders. Consistently getting quality rest isn’t a luxury; it’s a foundational health habit.
- Manage stress: Mental health conditions, especially depression and anxiety, were among the top contributors to years lived in poor health globally. Chronic stress feeds both. Building in daily stress management practices (whether that’s movement, mindfulness, time in nature, or social connection) matters more than most people realize.
The takeaway
We’ve gotten very good at extending life. What this research makes clear is that extending healthy life requires a different kind of effort, one focused less on treating disease after the fact and more on preventing the chronic conditions that accumulate over decades
