Sleep data from over 220,000 people reveal global differences in weekly sleep variability and sleep extension

A new study analyzing over 220,000 people's sleep data shows that those in Asia have shorter sleep duration and lower quality, with more variable sleep timing on weekdays. In contrast, people in other regions tend to have longer weekend sleep extension, suggesting a cultural impact on sleep habits.
