The further update of mobile phones has also enriched our lives. At the same time, more people can't live without mobile phones, which have become a part of our lives and can't be abandoned. However, we should know that mobile phones have advantages as well as disadvantages. We should make good use of them. Playing mobile phones also has many disadvantages. Long-term blue light radiation will do great harm to our eyes, and long-term bow will further damage our cervical spine. Just recently, the director of the Reproductive Center of Changsha Maternal and Child Health Hospital in Hunan Province introduced that he had received five pairs of mothers and daughters a day, all of whom came to see a doctor with their daughters in college. Three of the girls were diagnosed with premature ovarian failure. At the same time, they all have a common feature, that is, they stay up late to play games for a long time. One of the female students often stays up late to play games with some friends until two or three in the morning. In recent six months, he found himself always suffering from insomnia, irregular menstruation and love sweating, so he begged his mother to take him to the hospital for examination, and was finally diagnosed with premature ovarian failure, and heard that he might be infertile for life. It is said that health is the capital of revolution. This female college student is only in her early twenties, which is the best age in her life. Patients with premature ovarian failure are getting younger and younger, and it is precisely because young people like to stay up late now that this disease has a lot to do with staying up late for a long time. Moreover, the doctor director said that the peak of growth hormone secretion is from 10 to10 at night, which is beneficial to the recovery of body functions, including ovarian function. But now many young people stay up late, which will interrupt the recovery of ovarian function. If they stay up late for a long time, they will eventually lead to premature ovarian failure. This female college student was diagnosed with premature ovarian failure at a young age, which actually hit her hard. Patients with premature ovarian failure, accompanied by insomnia, memory loss and vaginal dryness, often repeatedly lead to serious problems such as vaginitis and urinary tract infection, and even make women prematurely aging. Therefore, in daily life, we must stay up late to avoid harm and play mobile phones moderately.
