Employees with High Workloads Tied to Increased Risk of Chronic Stress-Related Health Issues

International Research Links Longer Working Hours to Higher Obesity Risk

Researchers at the European Congress on Obesity in Istanbul have presented new findings suggesting a clear link between extended working hours and rising obesity rates. The study analyzed data from 33 OECD countries between 1990 and 2022 and found that a reduction in annual working hours can lead to lower obesity prevalence.

A 1 per cent reduction in annual working hours could lower obesity prevalence by 0.16 per cent, according to the study. This correlation is particularly evident in countries with the longest working hours, such as the United States, Mexico, and Colombia, which have higher obesity rates compared to northern European nations with shorter work weeks.

The study's lead researcher, Dr. Pradeepa Korale Gedara of the University of Queensland, attributes the link between long work schedules and obesity to stress caused by prolonged working hours. Elevated cortisol levels, a hormone linked to fat storage, are a result of stress, which can lead to irregular eating habits, reduced exercise time, and longer periods of sitting.

The World Health Organization has previously warned that long working hours increase the risk of heart disease and stroke, particularly among individuals with limited rest and poor sleep patterns. The study's findings add to the growing evidence that overwork affects more than just mental health.

Supporters of shorter work weeks argue that flexible schedules can improve public health by giving workers more time for exercise, healthy cooking, and sleep. Over 200 companies in the United Kingdom have already adopted four-day work week models in recent years, according to labour groups. However, some business groups remain cautious, citing concerns that reduced hours may not be practical for all industries.

Governments in several countries are favoring flexible labour policies over mandatory cuts in working time. Researchers behind the obesity study emphasize that the issue should be treated as both a health and economic concern. With global obesity rates continuing to climb, healthier workplaces and balanced schedules may become increasingly important in preventing lifestyle-related diseases.
