In China, a national survey in 2018 showed that 60% of people born after 1990 were not getting enough sleep, and that those living in the biggest cities suffered the most. People cited various reasons for this shortfall, including stress and their sleeping environment, but 37% blamed their hectic work or school schedule. The 2019 Phillips Global Sleep Survey, which received more than 11,000 responses from 12 countries, showed that 62% of adults worldwide feel they don’t get enough sleep, averaging 6.8 hours on a weeknight compared to the recommended amount of eight hours. A few hours of ‘own time’ is necessary to survive.”Įxperts have long warned that insufficient sleep is an unheeded global public-health epidemic. In a reply ‘liked’ more than 4,500 times, Twitter user Kenneth Kwok tweeted: “Typical 8 to 8 in office, arrive home after dinner and shower it’s 10 p.m., probably won’t just go to sleep and repeat the same routine. She described the phenomenon as when “people who don’t have much control over their daytime life refuse to sleep early in order to regain some sense of freedom during late-night hours”.

The phrase, which could also be translated as ‘retaliatory staying up late’, spread rapidly on Twitter in June after a post by journalist Daphne K Lee. Rao was doing what the Chinese have called ‘bàofùxìng áoyè’ – or ‘revenge bedtime procrastination’.

Often, Rao would stay up surfing the internet, reading the news and watching online videos until well after midnight. “I was deprived of all my personal life.” After her shift, which sometimes included overtime, she had a small window to eat, shower and go to bed – but she sacrificed sleep to eke out some personal time. Rao, who is originally from Nanjing, moved to financial hub Shanghai about five years ago to work for a multinational pharmaceutical company.

Emma Rao spent almost three years on China’s notorious ‘ 996 schedule’: working from nine in the morning to nine in the evening, six days a week.
