HOW well do you sleep? Joining hands with the popular health-science knowledge platform, www.DXY.com, and advisory institution Treed, the mattress brand Sleemon released the 2019 China Sleep Quality Index Report in Shenzhen on Monday, which is the report’s seventh annual release since 2013.

The report surveys 13 cities, including Shenzhen, Beijing, Shanghai and Chengdu, about the growth environment and population characteristics of the various generations since 1949, and systematically counts the changes in Chinese sleep culture and analyzes the sleep situations of the different generations.

Sleep conditions vary from generation to generation, and young people have a higher risk for developing sleep disorders and a lower chance of getting regular sleep.

The post-1950 generation, who qualify for retirement, go to sleep the earliest. The post-1960 generation has a relatively regular sleep schedule, whether on weekdays or weekends, according to the report.

The post-1970 and post-1980 generations have the shortest average sleep time on workdays. The post-1990 generation stays up too late, as their average sleep time is 11:50 p.m., and they normally play on their mobile phones for 50 minutes before falling asleep.

More than 21 percent of Chinese suffer from insomnia. The main causes of insomnia are mood swings, life stress and work stress. Young people are most vulnerable to losing sleep due to personal factors, such as emotion and stress. The elder generations tend to be more affected by external factors, such as the bed, environment and climate.

The report also suggests people in Shenzhen, which has a colorful nightlife, should pay more attention to their spine health.
