Chinese people are sleeping later on average than they did 10
years ago, but their total sleep time remains the same, research by
the Leisure Economy Research Center of Renmin University shows.
A survey on 2,000 people of all ages and different fields shows
people, especially 25 to 45-year-olds, tend to sleep 40 minutes
later than 10 years ago.
The survey listed 24-hour television, overtime work, increasing
demand for education, and in particular, the spread of Internet as
reasons for sleeping later.
However, the total sleeping remains the same at an average daily
eight hours and 41 minutes and one hour longer on days off.
The widespread use of household appliances has lightened the
burden of housework, allowing more time for rest. Meanwhile, more
people begin working at 9:00 AM, one hour later than 10 years ago,
which enables people to maintain their sleep time, according to the
survey.
Professor Wang Qiyan, of Renmin University, who has studied
sleep for more than 20 years, said, "Good sleeping habits and
reasonable sleeping period are beneficial to health and work
efficiency.
"If late-sleepers regularize their sleeping period and ensure
six to seven hours every day, their health will not be affected,"
he said.
