It is less and less possible for moderns to have enough sleep because of the busy school or work life. Sleeping without worries about waking up too eary and enjoying wonderful dreams are like “ the castle in the sky” for many people; not everyone can get it. A study shows that only Americans sleep more than seven hours each day over surveying many countries, such as Japan, Taiwan, Hong Kong, China, etc. It is said that people over 20 should get seven hours of sleep each night and those under 20, one more hour of sleep. Sleeping less than six hours a night can make one get sick easily, lose his/her attention at school or at work and leave one 12% more likely to die before 65 years old. But sleeping too much is not good for one, either. Sleeping longer than nine hours a night can make one 30% more likely to die before 65.
