"Stay up the deepest night, use the most expensive eye cream", a joke aptly depicts the living conditions of many young Chinese people. Insomnia has become a major problem facing contemporary society.
On the eve of World Sleep Day, the Chinese Sleep Research Association and other institutions jointly released the "2022 Chinese National Healthy Sleep White Paper", which described the "portrait of insomniacs" to the outside world. In China, who is staying up the deepest night? Which cities are the "hardest hit areas" for lack of awareness?

Nearly three-quarters of the Chinese surveyed had trouble sleeping
Survey data shows that the sleep status of Chinese people is not ideal, and nearly 3/4 of the respondents have had sleep troubles.
Among them, 12% of the respondents who often have sleep troubles (the frequency of sleep troubles in the past three months is greater than or equal to three days a week), 59.5% of the respondents who occasionally have sleep troubles (the frequency of sleep troubles in the past three months is less than or equal to two days a week), and the proportion of respondents who have never been troubled by sleep is only 26.3%.
From the perspective of the form of sleep distress, difficulty falling asleep has become the number one problem. In addition, mobile phones have become sleep killers, and nearly 70% of late sleep is associated with it.

More than 40% of young people stay up late until after midnight
According to the white paper survey, 44% of young people aged 19-25 stay up late until midnight, and 42% of the elderly sleep for more than half an hour, with an insomnia rate of 21%.
Young adults aged 19-35 are the age group with a high incidence of sleep problems, and poor sleep has gradually become a common pain point for young people. All ages generally sleep badly because of stress, and are highest in the 26-45 age group. For every two young adults who do not sleep well, there is one "pressure mountain".
The white paper also analyzed that in March 2021, the Ministry of Education issued a "sleep order" and in July of the same year, a "double reduction" policy was introduced. After the "sleep order + double reduction" policy, 60% of primary and secondary school students have increased their sleep time to varying degrees, of which the sleep time increased by more than 2 hours to 9.41%, the increase of 1 to 2 hours reached 21.66%, and the increase of 0 to 1 hour reached 28.88%.
However, primary and secondary school students still do not sleep enough. The Ministry of Education's "Sleep Order" clearly requires that primary/junior high school/high school students should sleep for 10/9/8 hours respectively. According to this survey, the average sleep time of elementary/middle/high school students is only 7.65/7.48/6.5 hours.
Which industry people are most lacking?
The survey shows that from a professional point of view, 74% of the service personnel work for more than two hours to deliver takeaways at night and deliver people by car. Entrepreneurs, entrepreneurs, and self-employed people have irregular work and rest accounted for 52%, and sleeping soundly accounted for 57%.
In addition, 69% of doctors wake up before 7 a.m., of which 49% sleep less than 6 hours. More than 60% of epidemic prevention personnel sleep less than 7 hours.
The courier and takeaway brother work hard, go out early and return late, and sleep less than the overall crowd.
The survey also shows that more than 56% of ride-hailing drivers drive for more than 4 hours at night. Two-thirds of ride-hailing drivers consider their sleep to be "average" or "more irregular.".
Office workers sleep an average of 7.5 hours People here stay up the most!

The report, released by the Sleep Medicine Professional Committee of the Chinese Medical Doctor Association, is based on 500,000 sleep data and 1,833 valid questionnaires in 2021, covering office workers over the age of 18 in 31 provinces.
Office workers sleep an average of 7.5 hours a day
Ye Jingying, chairman of the Sleep Medicine Professional Committee of the Chinese Medical Doctor Association, said that the survey showed that the average sleep time of the office workers interviewed was 7.5 hours, and only 22% of the sleep time could reach more than 8 hours, about 53% of the 6-8 hours, and 25% of the less than 6 hours. The data shows that the sleep time of office workers over the age of 35 gradually decreases with age.

Experts: Be wary of this "chronic killer"
Lu Lin, academician of the Chinese Academy of Sciences and president of the Sixth Hospital of Peking University, introduced that sleep is a highly conservative life phenomenon, which is closely related to biological evolution, species reproduction and individual survival and development, and sleep brain function plays an important role in normal life activities and the occurrence of major diseases.
Lu Lin introduced that with the rapid development of society, people's mental stress has increased, and the incidence of sleep-wake disorder has increased, which is associated with many mental illnesses, such as anxiety disorders, depressive disorders, schizophrenia, abnormal brain information processing: such as inattention, memory decline, abnormal decision-making, etc., and more importantly related to many common chronic diseases such as hypertension, myocardial infarction, dementia, obesity, immune dysfunction, so sleep-wake disorder is a "chronic killer" that cannot be ignored.
According to experts, the two most common types of sleep disorders are insomnia disorders and sleep breathing disorders, and the incidence of sleep disorders in the elderly population over 60 years old in mainland China is about 35.9%, and the incidence of sleep disorders in adolescents is 26%.
For the treatment of sleep disorders, Lu Lin said that most of the medical workers currently engaged in sleep diagnosis and treatment are doctors in respiratory, stomatology, otolaryngology, psychiatry and other disciplines, not a professional background in sleep medicine, and there is a certain bias in the identification of sleep diseases.
He said that sleep medicine as an independent disciplinary system is a necessary way to ensure the vigorous development of sleep medicine, and a sleep-related database and research platform that is standardized, standardized and integrated with multi-dimensional indicators should be built, and an information mining method integrating multimodal single comorbidities that integrates prediction, diagnosis and treatment and rehabilitation should be established to create a new model of sleep medicine research to promote the intersection of sleep medicine and multidisciplinary.
