On December 3, at the media meeting of the mainland Olympic athletes' delegation to Hong Kong, Su Bingtian talked about the secret of maintaining self-discipline. He said that in order to pursue dreams and goals, he has been strict with himself and formed a fixed pace of life. He goes to bed from 10:00 (22:00) to 10:30 (22:30) every day and doesn't need an alarm clock to get up. Subsequently, "Su Bingtian slept more than 10 o'clock every night and got up without an alarm clock" rushed to the microblog hot search. Netizens concluded: "self-discipline is the basis of success!" Su Bingtian's self-discipline actually established a lifestyle that can be emulated for more people. A recent study once again provides the scientific basis and benefits of why you sleep at 22-23 o'clock. Researchers at the University of Exeter studied the data of 88000 participants in the British biomedical library research project, and tracked their sleep and wake-up time within 7 days through an accelerometer worn on their wrists. The researchers then visited the subjects after an average of 5.7 years to determine the new diagnosis of cardiovascular disease. It was found that a total of 3172 people suffered from cardiovascular diseases, accounting for 3.6% of the total respondents. The overall result was that people who slept at midnight or later had the highest risk of cardiovascular disease, 25% higher than those who slept between 10:00 and 10:59 p.m; People who go to bed between 11:00 p.m. and 11:59 p.m. have a 12% higher risk. Su Bingtian insists on sleeping from 22:00 to 22:30. The benefits obtained are certainly conducive to his sports performance and prolong his sports career. Although many people are not professional athletes, Su Bingtian's sleep following the biological clock is still worth imitating. The 2021 white paper on exercise and sleep jointly released by China sleep research association and other institutions on March 18 this year shows that more than 300 million people in China have sleep disorders. Most people are difficult to sleep for many reasons, such as high work pressure, fast pace of life and so on. If people, like Su Bingtian, turn off and go to bed at 22-22:30, long-term persistence is expected to improve sleep and bid farewell to insomnia. Of course, for special people who work night shifts for a long time, it is also possible to ensure the quality of sleep by doing regular work and rest and self-regulation as much as possible. Su Bingtian's self-discipline actually has a longer-term goal. As far as the 100 meter dash is concerned, many European and American athletes can still achieve good results at the age of 35. Inspired by this, Su Bingtian believes that he can also create more miracles in terms of age. As long as good physical conditions are maintained, it is possible to continue to set new records. For others, imitating Su Bingtian's work and rest style is also of far-reaching significance, which is to maintain physical and mental health for a longer time at the end of self-discipline life. According to the statistical bulletin of the National Health Commission, the average life expectancy of Chinese residents will reach 77.3 years in 2019. But in real life, even if many people can live to be over 65 years old, the quality of life generally decreases. They are either ill in many parts of the body or partially or completely disabled. A study conducted by the Chinese Academy of social sciences on more than 8000 Chinese old people from 2008 to 2011 shows that the average remaining life of 65 year old people is about 16.04 years, and the expected time of complete self-care, mild disability, moderate disability and severe disability are 10.11 years, 4.42 years, 0.88 years and 0.63 years respectively. In the late stage of life, if you lose your ability, you will not only suffer, but also drag down your family. How can you talk about happiness. Therefore, minimizing disability time can not only make your life satisfactory, but also make the family unaffected. To achieve such a long-term goal, you can't overdraw your health when you are young. Su Bingtian's self-discipline provides such an example. Sleeping on time will not only improve and maintain the normal function of cardiovascular system, but also improve immunity, reduce diseases, and reduce disability or disability time in old age. Su Bingtian's self-discipline life and imitating Su Bingtian's self-discipline are not only the success of his career in the long run, but also the further guarantee of people's physical and mental health, longevity and high-quality life.
