Chinese youths know it isn't healthy to stay up late, but many say it’s hard to get an adequate night's sleep when there is not enough time at their disposal after work.

A report released by the Chinese Medical Doctor Association indicated that Chinese millennials slept for an average of 7.5 hours per night in 2018, lower than the standard line.

About 31.1 percent of young people stayed up late at night and got up late in the morning, while 30.9 percent stayed up late and got up early.

For some people, evenings are taken up by other activities such as hanging out with friends, or study, because as a whole, their leisure time is short.

Experts call on these people to improve workplace efficiency to avoid working overtime, and ask their employers to respect their right to rest so that they can better balance work and life, and perhaps allocate more time to sleep.

The report also showed that the average sleep quality index of Chinese millennials was 66.26 percent, 29.6 percent said they had bad sleep quality, and 12.2 percent suffered from insomnia.
