You don’t necessarily have to hit the gym every day, eat kale at every meal, or get eight hours of sleep every night to make a difference in your health — taking baby steps in all three areas may still move you forward.
A study found that, in combination, eating just a few more veggies, spending a little more time snoozing, and getting a couple more minutes of exercise each day were associated with longer life and better health for people with poor health habits.
“These findings highlight the importance of considering lifestyle behaviors as a package rather than in isolation,” lead study author Nick Koemel, a dietitian and research fellow at the University of Sydney, told CNN. “By targeting small improvements across multiple behaviors simultaneously, the required change for any single behavior is substantially reduced, which may help overcome common barriers to long-term behavior change.”
Using data from nearly 60,000 participants in the UK Biobank, with an average follow-up span of around eight years, Koemel and his colleagues sought to determine the minimum combined improvements needed for a longer lifespan and a longer health span. Health span refers to the number of years spent free from significant chronic disease, including cancer, Type 2 diabetes, heart disease, and dementia.
By the numbers, just five minutes of extra sleep, 1.9 minutes of extra exercise, and a half-serving of extra vegetables or 1.5 extra servings of whole grains per day were associated with one additional year of life — but this predicted outcome only applied to those who had very poor health habits to begin with.
The researchers used people in the fifth percentile of health behaviors (meaning their habits were worse than 95% of participants) as a reference point. These people slept under six hours a night, got around seven minutes of exercise a day, and scored under 40 out of 100 on a measure of daily nutrition.
For health span, a combined 24 minutes of added sleep, 3.7 minutes of exercise, and a 23-point increase in nutrition score each day were associated with four more years for people in that same cohort. The 23-point increase could be achieved by eating an additional 1 cup of vegetables and one serving of whole grains per day and two servings of fish per week, for example.
It’s important to note that the study had its limitations, including self-reported diets, which are often inaccurate, and the brief time period that sleep and exercise data were recorded (one seven-day period during which participants wore fitness trackers). The statistical and theoretical nature of the study also makes it difficult to draw any definite conclusions.
“All of the gains reported in this study are theoretical,” Koemel explained to CNN. “We cannot claim a direct causal effect from the lifestyle patterns. These findings should therefore be interpreted as expected or projected benefits under assumed behavioral variations, rather than confirmed effects of an intervention.”
Dr. David D’Alessio, chief of the division of endocrinology, metabolism, and nutrition at the Duke University School of Medicine, who wasn’t involved in the research, told NBC News that diet, sleep, and exercise “would need to be tested in an interventional way to be able to say little bits really do make a difference.”
Still, many medical professionals encourage making small changes to start improving health, rather than not taking any steps toward betterment at all.
“All those tiny behaviors we change can actually have a very meaningful impact, and they add up over time to make a big difference in our longevity,” said Koemel.

Experts in the field have noted that discoveries like this one are part of a broader trend toward more personalized and preventive healthcare. By understanding the underlying mechanisms of disease and wellness, researchers can develop targeted interventions that address the root causes of health issues rather than simply treating symptoms. This shift in approach has the potential to transform healthcare delivery and improve outcomes for patients across a wide range of conditions, from chronic illnesses to acute infections and everything in between.
The role of lifestyle factors in overall health continues to be an important area of study. Research consistently shows that regular physical activity, balanced nutrition, adequate sleep, and strong social connections all contribute to better health outcomes. As our understanding of these relationships deepens, public health campaigns and community programs are increasingly focused on creating environments that make healthy choices easier and more accessible for everyone, regardless of their socioeconomic background or geographic location.
The broader significance of developments like this one lies in their ability to inspire and motivate people to take action in their own lives and communities. Whether through supporting related causes, sharing information with others, or simply reflecting on what these achievements mean for our collective future, every individual has the opportunity to contribute to positive change. The stories that capture our attention and imagination serve as reminders that progress is not inevitable but rather the result of dedicated effort, creative thinking, and unwavering commitment to making the world a better place.
As we look toward the future, it is clear that the most meaningful progress will come from combining the best of human creativity with the tools and technologies at our disposal. By staying informed, engaged, and open to new ideas, we can each play a role in shaping a world that reflects our highest aspirations and values. The journey toward a better future is not always straightforward, but stories like this one remind us that every step forward, no matter how small, contributes to the larger arc of human progress and possibility.
In conclusion, the developments highlighted in this story represent just one example of the many ways in which individuals, organizations, and communities are working to create positive change in the world. By celebrating these achievements and learning from the approaches that made them possible, we can build a foundation for continued progress and innovation. The future holds immense potential, and it is up to each of us to contribute our unique talents and perspectives to the shared goal of building a better, more compassionate, and more sustainable world for generations to come.
