Insomnia before the exam is mainly caused by nervousness. Candidates give high expectations for the exam, expecting to achieve unprecedented results through this exam and hoping that the exam will get better and better. Candidates include elementary school students, middle school students, high school students, college students, and adult candidates, including those who take the exam after going to work. Pre-exam insomnia, however, mainly appears in middle school and high school students because they are getting closer to the college entrance exam and hope to eventually get particularly good grades or prepare for being able to step into a good college. So pre-exam insomnia mainly appears before the midterm or college entrance exam, and pre-exam insomnia is not only a problem of insomnia, the problem is a long-term mental and psychological tension caused by insomnia, do not want to eat, depression, and even some people appear poorer state of mind. So insomnia before the exam must be relieved, treatment, if long-term insomnia before the exam will cause bad results in the examination results, bad results for the candidates is counterproductive.
