Medical research also shows that the alienation of human sympathetic nerve activity and metabolism is dominant during the day, while the assimilation of parasympathetic nerve and body is dominant at night. Therefore, excessive use of the brain at night will make people's body rhythm disorder, and there will be symptoms such as insomnia, dreaminess, malaise, loss of appetite, irritability, distraction, decreased thinking ability and slow response.
It can be seen that staying up late is harmful to physical and mental health. However, some people mistakenly believe that as long as you add nutritional supplements after staying up late, it will not affect your health. This is also taken for granted. As the saying goes: "It is better to sleep with a pig than to eat it!" No tonic can make up for the loss of sleep. Because of endocrine disorders and neurasthenia, it is not only effective to strengthen nutrition. Therefore, mental workers, especially teenagers, should reasonably arrange their own pace of life, strive for regular daily life and rest, ensure adequate sleep at night, and have sufficient energy to study and work.
Sleep research experts at Stanford University School of Medicine in the United States pointed out that if you want to do better during the day, the method of reducing sleep will not achieve results. On the contrary, the busier you work, the more you need enough sleep to ensure it. No matter what job you do, the best way is to try to add an hour to the length of inertial sleep.
Sleep is a natural phenomenon in people's lives. According to China's work and rest system and habits, a person's day is roughly divided into three parts: 8 hours of work and labor, 8 hours of rest (including housework and social entertainment) and 8 hours of sleep. So one third of human life is spent in sleep. Sleep is very important for people, and the quality of sleep is one of the important signs of people's health. Lack of sleep can lead to all kinds of serious consequences. An article in Time magazine pointed out that lack of sleep has become the most common health and social problem in the United States today. Although researchers have not produced convincing evidence today that lack of sleep may directly lead to diseases, some studies have confirmed that lack of sleep may make people's mental state worse and their ability to do things seriously decline. Pollack, a scholar at Cornell University, said: "People who don't get enough sleep can't think, make proper judgments, and stay focused for a long time." A recent survey by the American Cancer Society shows that people who sleep 7-8 hours a night live the longest, and those who sleep 3-4 hours have twice the death rate. Sleep more than 10 hour, 80% is short.
Taking a nap for about half an hour in summer can also prevent coronary heart disease.
Some recent data show that siesta is the main cause of traffic accidents and industrial disasters. Every year, 200,000 traffic accidents in the United States are related to siesta, and some major railway and air crashes are also related to lack of sleep. In all workplaces, human error accounts for 60% to 90%, and in human error, lack of sleep is an important factor, at least no less than drug abuse, alcoholism and equipment failure. Another study shows that lack of sleep is one of the reasons for students' drug abuse and decline in academic performance. According to a survey, in schools in Canada, the memory of students with insufficient sleep is only one-third to one-half of that of students with adequate sleep.
Summary:
The results of this research study show that although burning the midnight oil can make full use of time to a certain extent, there are surging waves at the bottom of the calm lake-it is not conducive to physical and mental health, and health is the capital of the revolution. Without physical support, how can we talk about studying hard and serving the motherland? Without capital, no matter how beautiful the flowers are, they can't bear fruit! In other words, very few students have improved their grades by burning the midnight oil, and it is not obvious. Why do we insist on this thankless thing? Man's wisdom lies in knowing how to reflect. If reading at night doesn't achieve much, give it up! Burning the midnight oil to read books not only takes up our sleep time, but also leads to our inattention and drowsiness in class the next day. Moreover, it may also affect other people's sleep (we spend more time in the dormitory in senior three) and bring trouble to others. This is a manifestation of selfishness and a portrayal of immaturity. We are high school students and should be responsible for our actions. We should know how to make good use of our time, but we should not blindly spend our time on such inefficient things as burning the midnight oil. If we seize every minute of the day, it is totally unnecessary to burn the midnight oil at night! Medical research also shows that the alienation of human sympathetic nerve activity and metabolism is dominant during the day, while the assimilation of parasympathetic nerve and body is dominant at night. Therefore, excessive use of the brain at night will make people's body rhythm disorder, and there will be symptoms such as insomnia, dreaminess, malaise, loss of appetite, irritability, distraction, decreased thinking ability and slow response. So for our health, for our study and for our future, please choose carefully!
Experience:
In this research activity, when we ask students to fill out questionnaires and investigate questions from some students, some students will ignore and despise us. We understand the importance of interpersonal communication and the necessity of learning communication skills. Schools can be said to be the epitome of a society. We can learn some qualities that we must have when facing the society in the future through one study, which is very beneficial to our future development. Secondly, we have a deeper understanding of the problem of burning the midnight oil, and we will make careful consideration and choice on this issue in the future. And no longer just think it is good, understand the two sides of things, and look at the problem from a dialectical point of view in the future. In this research activity, we deeply feel that we are mature and much older, and understand the importance of thinking. In our opinion, this should be the most meaningful research activity!
