　　Celebrating Sleep

　　World Sleep Day，observed on 21 March，was created to bring attention to the growing number of sleep problems worldwide.Sleep is a natural part of human life，but many people in the modern world ignore its importance.As a result，sleep problems are increasingly common.

　　In 2002，scientists at the University of Athens in Greece conducted a survey of over 35,000 people in 10 countries around the world，including China，Belgium and South Africa.Of the people that responded to the survey,24 percent said that they did not sleep well，and based on their responses,31.6 percent were diagnosed(诊断)with insomnia(失眠)and another 17.5 percent were diagnosed with borderline insomnia.In addition,30.7 percent of survey respondents reported visiting a doctor for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.

　　Overall，the survey found that ninny people suffer the effects of poor quality sleep，some examples of which are being unable to fall asleep and waking up in the middle of the night.The main factors causing these problems are pressure from school or work and a fast pace of life，but noise pollution and light pollution also interfere with sleep and contribute to poor quality sleep.The survey’s findings are particularly troubling because large numbers of people were found to have difficulty sleeping at night.The short­term effects of this are tiredness and trouble concentrating.If this happens for a long time，the risk of putting on weight and having a heart attack may increase.
