Results of the survey show that some 55 per cent of the respondents admitted that work pressures have affected their sleep patterns and they have resorted to various methods to improve sleep quality.
The survey was conducted in November and December through random household visits in 20 cities, 20 towns and 20 villages.
According to Qin Xiaoming, vice head of the Chinese Medical Doctor Association, which sponsored the report, the survey revealed a trend in which people in south and west China tend to sleep better than those in the north and east, and bachelors sleep better than the married.
Noting new media's negative influence on sleep, the survey found that 67. 1 per cent of people chat on mobile phones or computers before sleeping, and 43.2 per cent of those going to bed after midnight do so due to online gaming and messaging.
Stressing moderate sleep durations, the report urged people to avoid overusing networking devices, while turning to relaxing music, massage and naps to improve sleep quality.
