Many Chinese do not sleep well, but most of them do not pay enough attention to the issue, according to the 2013 China Sleep Quality Index released by the Chinese Medical Doctor Association in Beijing on March 19, to mark World Sleep Day, which falls on March 21.

The report was based on a survey jointly conducted by Sleemon Furniture Co and Horizon China, a leading survey and research company. They interviewed more than 107,000 respondents from households in 20 cities, 20 counties and 20 rural areas across China in November and December 2012.

According to the report, Chinese people sleep on average for eight hours and 50 minutes every day - much more than the seven to eight hours' sleep recommended by medical experts. But, about 50 percent still feel groggy and weak when they wake up in the morning.
