Working late may be affecting more than employee burnout. New international research suggests longer working hours are also linked to higher obesity rates, adding another layer to the growing debate around work-life balance and the future of work.
Researchers found countries with longer average working hours often had higher obesity levels, while nations with shorter working schedules tended to report lower rates, according to The Times.
The study argues that long workdays can leave employees “time poor,” making it harder to cook healthy meals, exercise regularly, or manage stress levels effectively.
Researchers also pointed to elevated cortisol, a stress hormone associated with weight gain and fat storage, as a possible contributing factor.
Four-Day Week Debate Expands Beyond Productivity
The findings are already feeding into conversations around four-day workweeks and employee wellbeing.
According to the analysis, even modest reductions in working hours were associated with small declines in obesity rates at a population level. Researchers suggested shorter workweeks could potentially improve public health outcomes by giving workers more time for sleep, exercise, meal preparation, and recovery.
Future of Work Focus Shifts to “Time Poverty”
The research highlights a growing workplace issue known as “time poverty,” where employees may technically earn enough income but lack the time or energy needed to maintain healthy routines.
That challenge has become more prominent in future-of-work conversations, particularly as hybrid work, burnout concerns, and flexible scheduling policies continue influencing how employees evaluate job quality.
Critics of shorter workweeks argue reduced hours could negatively affect productivity or income levels, especially in already strained economies. But supporters increasingly frame flexibility not only as a workplace benefit, but as a broader public health issue.
