New research published January 14, 2026, in The Lancet and eClinicalMedicine demonstrates that even incremental improvements to daily routines-such as adding just five minutes of walking or slightly adjusting sleep schedules-are significantly linked to lower mortality rates. The studies, analyzing data from over 200,000 participants across multiple countries, reinforce the growing understanding of lifestyle’s powerful impact on longevity and suggest that public health messaging should focus on achievable changes rather than sweeping overhauls. These findings arrive as healthcare systems worldwide grapple with rising rates of chronic disease and aging populations.
Even small increases in physical activity and improvements to diet and sleep are strongly linked to lower mortality rates, particularly among those with the least healthy lifestyles, according to two studies published January 14, 2026, in The Lancet and eClinicalMedicine. These findings reinforce the growing body of scientific evidence demonstrating that even modest lifestyle changes can have a significant positive impact on health and longevity.
One study published in The Lancet focused on the impact of adding just five minutes of moderate-intensity physical activity – such as walking at an average pace of 5 kilometers per hour – to one’s daily routine. Researchers found that this small increase in activity was associated with a 10% reduction in all-cause mortality for most adults, who currently average around 17 minutes of moderate-intensity activity per day. For those who are least active, averaging only about 2 minutes of this type of activity daily, the same increase was linked to a roughly 6% reduction in all-cause mortality.
The research also showed that reducing sedentary time by 30 minutes each day was associated with an estimated 7% reduction in all-cause mortality among adults who spend 10 hours a day sitting, and around a 3% reduction for those who are sedentary for 12 hours a day. Additionally, engaging in just 10 more minutes of moderate-intensity activity daily was linked to a 15% reduction in all-cause mortality for most adults and a 9% reduction among the least active.
The study analyzed data from more than 135,000 adults across seven cohorts in Norway, Sweden, and the United States, as well as from the UK Biobank, with an average follow-up period of eight years. By using data from activity trackers and assessments of sedentary time, the researchers estimated the proportion of deaths that could potentially be prevented through small daily increases in physical activity or reductions in sitting time.
“This research consolidates existing evidence with an extensive population sample, which is particularly relevant in a context where pharmacological approaches receive more attention than the well-established importance of lifestyle factors,” said Luis Cereijo, a public health researcher at the University of Alcalá de Henares, in response to the study.

Sleep, Physical Activity, and Nutrition
A separate investigation published in eClinicalMedicine, a journal within The Lancet group, found that combining small improvements in sleep, physical activity, and diet can lead to a longer life, especially for individuals with the least healthy habits. The study suggests that these small changes can have a cumulative effect on overall health and lifespan.
Researchers determined that adding five minutes of sleep, two minutes of moderate-to-vigorous physical activity (like brisk walking or climbing stairs), and half a serving of vegetables to one’s daily routine could result in an extra year of life for those with the poorest sleep, exercise, and dietary habits.
An optimal combination of behaviors – including 7 to 8 hours of sleep, 40 minutes of moderate-to-vigorous physical activity daily, and a healthy diet – could potentially add more than 9 years of life expectancy and good health.
The findings from this second study were based on data from nearly 60,000 participants from the UK Biobank, recruited between 2006 and 2010, with an average follow-up of eight years.
Both studies focused on the broad societal benefits based on data collected in wealthier nations and did not examine individuals directly. The authors emphasize the need for further research in lower-income countries.
Small Changes, Significant Benefits
Despite the observational nature of both studies, they reinforce the evidence that very small and realistic lifestyle changes can have important benefits in reducing all-cause mortality, experts noted in responses to the research published in Science Media Centre. This research underscores the potential for public health initiatives focused on promoting accessible and achievable lifestyle modifications.
Just over a month ago, research published in Nature Medicine concluded that moderate physical activity may delay the onset of Alzheimer’s disease symptoms by up to seven years in individuals at risk.
Last summer, a team of researchers at the Cajal Neuroscience Center of the CSIC demonstrated in an animal model that moderate exercise improves the health of the gut microbiota, which in turn has very positive repercussions on brain cognitive performance.
The journal JAMA also recently published a study showing that people who engage in physical activity after the age of 60 reduce their risk of death or cardiovascular disease by 30 to 40%.
