▍原文 A new study suggests a link between longer working hours and higher obesity rates. The international study, presented at ECO 2026, compared working patterns and obesity prevalence across 33 OECD countries from 1990 to 2022, noting that a 1% reduction in annual working hours was associated with a 0.16% decrease in obesity rates. Researchers found that increased desk work can reduce time for exercise, while extended hours may contribute to stress-related eating and elevated cortisol levels, both associated with weight gain. ▍語言點 1. a link between A and B A與B之間的關聯 2.
