July 22 (UPI) -- A four-day work week can lead to happier and more productive, dedicated employees, a new global study found.
Workers at companies that instituted a four-day work week -- essentially working 80% of their regular hours for the same pay -- reported less burnout and better job satisfaction along with improved mental and physical health, researchers report in Nature Human Behavior.
"Across outcomes, the magnitude [of improvement) is larger for the two work-related measures - burnout and job satisfaction - followed by mental health, with the smallest changes reported in physical health," wrote the research team co-led by Juliet Schor, an economist and sociologist at Boston College.
For the study, researchers conducted six-month trials involving nearly 2,900 employees at 141 businesses or organizations that adopted a four-day work week in Australia, Canada, New Zealand, the U.K., Ireland and the United States.
The team compared employee well-being at those firms with that of about 290 employees at 12 other companies that didn't try out the abbreviated work week.
People given a four-day week had, on average, five fewer hours of work per week, results show.
Workers who had a reduction of eight or more hours in their work week reported larger decreases in burnout and increases in job satisfaction and mental health, compared with employees at companies that stuck to a five-day schedule, researchers said.
But even workers who wound up with less time off during their four-day week still received smaller but similar benefits, researchers found.
"There is a clear dose-response relationship for individual-level hours: greater reductions in hours worked predict larger improvements in subjective well-being," researchers wrote.
Better sleep, improved effectiveness on the job and less fatigue appear to explain the improvements that occurred among employees with a four-day work week, researchers found.
"Increases in perceived work ability - at both company and individual levels - indicate that the work reorganization process opened up by four-day weeks has led to profound changes in the job experience itself, improving workers' individual and collective sense of performing their jobs well," researchers wrote.
Overall, the findings suggest that "an organization-wide reduction in hours can stimulate workers to collectively adjust and optimize their workflows, leading to improved work ability and well-being," researchers concluded.
However, they noted that the companies that participated were already interested in trying a four-day work week, and therefore, might have been more supportive of employee well-being from the start.
More studies including larger numbers of different types of companies are needed to verify that a four-day work week could benefit both employees and their businesses, researchers said.

Walking for health? A faster pace improves benefits

While it's known that regular walking is healthy, the new study from Vanderbilt University suggests maintaining a peppy pace is key. Photo by Adobe stock/HealthDay July 29 (UPI) -- Want to cut your odds of an early death by almost 20%? Take just 15 minutes out of your day for a brisk walk, researchers advise. While it's known that regular walking is healthy, the new study suggests maintaining a peppy pace is key. "Individuals should strive to incorporate more intense physical activity into their routines, such as brisk walking or other forms of aerobic exercise," concludes study lead author Lili Liu of the Vanderbilt Epidemiology Center at Vanderbilt University in Nashville, Tenn. Recommendations for brisk walking aren't new. The U.S. government's Physical Activity Guidelines for Americans says: "To attain the most health benefits from physical activity, adults need at least 150 to 300 minutes of moderate-intensity aerobic activity, like brisk walking or fast dancing, each week." However, as Liu's team noted, most research has focused on the health benefits of brisk walking among affluent, white Americans. The new study was published Tuesday 29 in the American Journal of Preventive Medicine and involved predominantly low-income Black Americans living in 12 southeastern states. Nearly 80,000 adults aged 40 to 79 were included in the study. As the researchers noted, many of these people lived in poorer areas with relatively high levels of pollution and few "safe walking spaces." Study participants were asked how many minutes per days they might spend "walking slowly (such as moving around, walking at work, walking the dog or engaging in light exercise)" and/or "walking fast (such as climbing stairs, brisk walking or exercising)." Statistics on deaths among the group were collected between 2002 and 2022 for a median of nearly 17 years. (Median means half were followed a shorter time, half for a longer period.) During follow-up, close to 27,000 participants died. The study's main finding, according to study senior author Dr. Wei Zheng: "Our research has shown that fast walking as little as 15 minutes a day was associated with a nearly 20% reduction in total mortality [deaths], while a smaller reduction in mortality was found in association with more than three hours of daily slow walking." Even after accounting for other lifestyle factors such as a person's diet, smoking status and other forms of exercise, "this benefit remained strong even after accounting for other lifestyle factors," said Zheng. He's also at Vanderbilt's Division of Epidemiology. The new findings echo those of prior studies that focused on wealthier, predominantly white populations. They suggest that communities may want to invest in "resources and support to facilitate increased fast walking" within their neighborhoods, Liu said in a journal news release. Just how might a brisk daily walk boost your health? According to the researchers, aerobic exercise like this improves the heart's efficiency, including its overall output, oxygen delivery and pumping action. At the same, regular brisk walks help ward off obesity, high cholesterol and high blood pressure, the researchers said. "These findings underscore the importance of promoting fast walking as a feasible and effective strategy to improve health outcomes," the Nashville team concluded.

Most liver cancers are preventable, study says

July 29 (UPI) -- Liver cancer: In most cases, it doesn't have to happen, a new global study finds. Research suggests that 60% of cases of this often deadly disease are preventable by avoiding or treating big risk factors. Those risk factors include viral hepatitis infection, alcohol misuse or a dangerous, obesity-linked buildup of fat in the liver. The finding highlights "a huge opportunity for countries to target these risk factors, prevent cases of liver cancer and save lives," said study first author Dr. Stephen Chan of the Chinese University of Hong Kong. His team issued its findings Monday in a special report on liver cancer published by The Lancet. As Chan's team notes, liver malignancies rank as the sixth most common cancer worldwide and the third-leading cause of cancer deaths. Some countries are being hit much harder than others: China, in particular, is burdened with more than 40% of the world's liver cancer cases, largely due to widespread hepatitis B illness. Without further intervention, cases of liver cancer are expected to nearly double globally by 2050 to more than 1.5 million cases annually, the report found. When cancer affects the body's blood-cleansing organ, it can be very difficult to treat. "It is one of the most challenging cancers to treat, with five-year survival rates ranging from approximately 5% to 30%," noted report co-author Dr. Jian Zhou of Fudan University in China. "We risk seeing close to a doubling of cases and deaths from liver cancer over the next quarter of a century without urgent action to reverse this trend." Many cases of liver cancer can be avoided. One preventable cause is metabolic dysfunction-associated steatotic liver disease, or MASLD -- a slow, steady buildup of fat within the liver, often tied to obesity. Up to a third of people worldwide have some level of MASLD, according to the researchers, and as obesity rates rise, cases of the condition are expected to follow suit. By 2040, it is projected that 55% of Americans will have MASLD, upping their odds for liver cancer, the report's authors said. "Liver cancer was once thought to occur mainly in patients with viral hepatitis or alcohol-related liver disease," noted report co-author Dr. Hashem El-Serag of Baylor College of Medicine in Houston. "However, today rising rates of obesity are an increasing risk factor for liver cancer, primarily due to the increase in cases of excess fat around the liver." On the other hand, inroads made against viral hepatitis B (HBV) and C (HCV) mean their impact on liver cancer rates are waning. The authors note in a journal news release that "the proportion of liver cancer cases linked to HBV is expected to decrease from 39% in 2022 to 37% in 2050, while HCV-related cases are projected to drop from 29% to 26% over the same period." Better efforts to vaccinate against hepatitis B and screen for (and treat) hepatitis C could drive down liver cancer rates even further, the team said. Diagnosing and treating MASLD would also help. "One approach to identify patients at high risk of liver cancer would be to introduce screening for liver damage into routine healthcare practice for patients at high risk of MASLD, such as individuals living with obesity, diabetes and cardiovascular disease," El-Serag said in the news release. Better advocacy around healthy diets and regular exercise can also help, he added. Even cutting liver cancer cases by 2% to 5% per year could mean that 9 million to 17 million new cases of liver cancer could be prevented worldwide by 2050. That translates to up to 15 million lives saved, the report's authors said. More information Find out more about MASLD and liver cancer at the Fatty Liver Alliance. Copyright © 2025 HealthDay.
