Entering the brand-new technological era of the 21st century, people’s health consciousness has been raised unprecedentedly, and the new concept of “having health to have everything” has been deeply rooted in people’s hearts, so the problem of sleep has aroused the attention of the international community. According to a survey conducted by the World Health Organization on 25,916 patients in primary care in 15 regions of 14 countries, it was found that 27% of them had sleep problems, and it was reported that the incidence of insomnia in the United States was as high as 32-50%, 10-14% in the United Kingdom, 20% in Japan, 30% in France, and more than 30% in our country, and that 50% of the students had sleep deprivation. Sleep disorders have a significant negative impact on the quality of life, but a significant number of patients do not receive reasonable diagnosis and treatment. Sleep disorders have now become a prominent problem that threatens the public in all countries of the world. To raise awareness of the importance of sleep, the Global Sleep and Health Program, sponsored by the International Foundation for Mental Health and Neuroscience, launched a global campaign in 2001 to designate March 21, the first day of spring, as “World Sleep Day”. The focus of the campaign is to draw attention to the importance of sleep and the quality of sleep. “The reason why World Sleep Day is set on the first day of spring every year is that the cyclical nature of seasonal changes and the diurnal pattern of sleep are closely related to our daily life. In 2003, the China Sleep Research Association officially introduced World Sleep Day into China.
