Little Lifestyle Tweaks for a Healthier Life

According to a new Australian study published in eClinicalMedicine, small lifestyle changes in diet, exercise, and sleep can extend life by about a year, while more substantial changes may add over nine years. Improving these habits not only boosts longevity but also increases “health span”, the number of years lived without major health problems.

For the study, Australian researchers reportedly analyzed the behaviors of more than 59,000 older adults using data from the UK Biobank, a large database of health, lifestyle, and demographic information. Participants wore wrist devices to track sleep and physical activity, while diet quality was assessed through self-reported eating habits.

The study, revealed that people with the poorest health habits could gain about one extra year of life through small combined changes: five more minutes of sleep per night, roughly two additional minutes of daily exercise, and a five-point improvement in diet quality. The same benefit could also be achieved by making a larger change in just one area, 25 more minutes of sleep, about 2.3 extra minutes of exercise per day, or a 35.5-point increase in diet quality.

A recent CNN article covering the findings featured an interview with Nick Koemel, the study’s lead researcher and a research fellow in physical activity, lifestyle, and population health at the University of Sydney’s Camperdown campus. He noted:

These findings highlight the importance of considering lifestyle behaviors as apackage rather than in isolation. 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.

A similar study by Norwegian researchers, published in the journal The Lancet, and reported by NBC News, found that reducing daily sitting time by 30 minutes was linked to a 7% lower risk of death. The study also showed that just five minutes of vigorous exercise or 30 minutes of light physical activity per day reduced mortality risk by 10% and 5%, respectively.

Below is a concise summary of key findings from the studies, as reported by CNN and NBC News:

  • Sleep gains and losses add up: Nearly 37% of U.S. adults get less than the recommended seven hours of sleep per night, increasing health risks. Adding just 30 minutes of sleep is a realistic way to improve overall health.
  • Move more to live longer: Exercise benefits peak at around 50 minutes per day, with diminishing returns beyond that. Even small increases, such as going from no activity to 10 minutes of walking daily, can deliver meaningful health gains.
  • Focus on small nutritional improvements: Dr. David D’Alessio of Duke University notes limitations in the Australian study, including self-reported diet data and short monitoring periods for sleep and exercise. He emphasizes the need for interventional studies to better assess how small lifestyle changes affect health.

Echoing this point, Prof. Glenn Gaesser of Arizona State University, told NBC News, that while changing fitness habits is challenging, small steps can make a big difference.

Those going from zero to 10 minutes a day of walking will experience more benefit than someone who’s going from 30 to 40. Beyond 40, you get a law of diminishing returns. It doesn’t require a mass overhaul of your lifestyle to achieve health benefits

These studies highlight that small, manageable improvements in sleep, exercise, diet, and daily movement can meaningfully extend both lifespan and health span, especially for those with the poorest habits. The evidence shows that even a few extra minutes a day—done consistently—can deliver real health benefits without requiring a complete lifestyle overhaul.
