About half of Chinese adults sleep less than eight hours every night, a new report said. The report was based on a survey of 6,168 people aged 18 to 70 from July to November, 2022.
People with lower level of education have less sleep and lower sleep quality (质量), according to the report. Those with higher level of education may sleep longer and better.
The report showed a relationship between a person's income (收入) and the quality of their sleep. People from families making less than 3,000 yuan ($435) a month get the least amount (数量) of sleep and experience the worst sleep quality, while those with mid-level incomes sleep longer and generally reported good-quality sleep. For people making more than 10,000 yuan a month, they sleep less than those with mid-level incomes, but they reported a better quality of sleep.
The report also found that people who exercise often enjoy the best sleep quality, with 85 percent of them saying they have "very good" sleep quality. More than 80 percent said they can fall asleep in less than half an hour, and only 1.8 percent said they have trouble falling asleep.
University students sleep the longest, followed by white-collar (白领) workers, blue-collar workers and jobless people. However, university students usually stay up late, which results from the use of phone s and computers, over-thinking, stress and their sleeping environments. Sleep is important in improving health and memory. Although many university students know that good sleeping habits are conducive to good health, many say they don't change their bad habits.
