Westerners are more likely to go to bed earlier and have longer lie-ins at the weekend than people in Asia, which could potentially have knock-on health effects.

Michael Chee at the National University of Singapore and his colleagues have analysed anonymised data collected from 220,000 people in 35 countries using sleep trackers between January 2021 and January 2022.

Most of the countries were either Western or Asian and there were, on average, about 242 nights of data for each wearer.
