Could a four-day workweek help combat rising obesity rates?

A new study suggests that shorter working weeks could help reduce obesity rates. Researchers found a possible link between long hours and higher obesity levels across 33 countries. The findings come as over 200,000 UK workers have already switched to a four-day week since the pandemic. Dr. Pradeepa Korale-Gedara, from the University of Queensland, led the international research. The study analysed data from OECD nations and found that a 1% cut in annual working hours was tied to a 0.16% drop in obesity rates. Countries with longer working cultures tended to have higher obesity levels.

The report suggests that work-related stress and lack of time for exercise may play a role. If applied in the UK, a four-day week could potentially lead to around half a million fewer obese people. However, the study does not prove direct causation, and factors like income may also influence obesity rates.

Critics, including Dr. Christopher Snowdon of the Institute of Economic Affairs, remain sceptical about the connection. Despite this, the 4 Day Week Foundation continues to push for the policy’s adoption in the UK. The research highlights a potential benefit of reduced working hours on public health. Over 200,000 British employees have already adopted a four-day week since 2020. While the findings suggest a trend, experts stress that further evidence is needed to confirm the impact on obesity.
