"Sleep for 9 hours a night, why do you want to sleep so much during the day?" Xiao Li, who works in a company, can hardly control himself. When he wanted to sleep, he fell asleep at his desk. Colleagues in the office laughed and called him "Sleeping God", but he delayed a lot of work and was scolded by his boss. Pan Jiyang, director of the psychiatric department of the First Affiliated Hospital of Jinan University, said that every time we talk about sleep disorders, we naturally think of insomnia. In fact, not only insomnia is a major category of sleep disorders, but also excessive sleepiness during the day. Moreover, sleepiness is likely to be a signal of other diseases in the body, which should arouse our great attention. If drowsiness occurs in extremely inappropriate occasions such as working high above the ground and driving, it may also be life-threatening. Sleepiness is a sign of other diseases. Sleepiness is closely related to sleep disorders, such as sleep apnea and narcolepsy. Xiao Li is a narcolepsy patient. When he wants to sleep during the day, he will have irresistible sleep attacks. Even if he tries to stay awake, he can't completely control it. /kloc-fall asleep after 0/~ 2 minutes, sometimes several times a day. Narcolepsy often occurs after doing monotonous and quiet work or eating. Sleepiness can be mild, such as taking a nap after lunch, and serious symptoms can be falling asleep quickly when eating or talking. I doze off during the day mainly because I can't sleep at night. Some patients always think that insomnia at night is the main cause of daytime sleepiness, but Pan Jiyang thinks that this is not necessarily the case. Generally speaking, it is not normal for patients to feel sleepy after meals or watching TV, which usually indicates sleep deprivation, and obstructive sleep apnea syndrome is one of the reasons. Therefore, I always feel sleepy during the day, suggesting that my body may have sleep disorders or other diseases and need sleep monitoring. Sleepiness should not be taken lightly. Pan Jiyang pointed out that some patients have drowsiness, and sometimes this symptom is mild and the patient himself is not aware of it. However, if sleepiness occurs in extremely inappropriate occasions such as working high above the ground and driving, it may be life-threatening. In the United States, there are 2 million traffic accidents every year, and about 40 thousand to 50 thousand people die. The driver's uncontrollable instantaneous drowsiness is a major cause of traffic accidents and is considered as a "super killer" on the road. Old people are most afraid of insomnia. Some old people say that they can eat and sleep, and they have to take a nap during the day. They feel very happy. Studies have proved that sleepy old people are prone to heart disease. A recent study by Dr. Newman from the University of Pittsburgh School of Medicine confirmed that the prevalence of heart disease in elderly women who are sleepy during the day is 66% higher than that in women who are not sleepy during the day. The prevalence of heart disease in elderly men who are sleepy during the day is higher than that in those who are not sleepy during the day. In addition, once suffering from heart disease, the mortality rate is higher by 28% and 16% respectively. Therefore, sleepiness should not be taken lightly. In the case of "can't sleep at night and can't wake up during the day", you should go to the hospital sleep center for treatment. Avoid engaging in dangerous work and driving before treatment to prevent accidents. People with somnolence symptoms should see a doctor, and need to do sleep monitoring, pay attention to the examination and treatment of possible primary diseases, such as sleep apnea syndrome, narcolepsy, restless legs syndrome and so on. Patients with sleep apnea syndrome snore at night, wake up or sleep uneasily at night, and feel sleepy or tired during the day. If doctors give antipsychotic drugs to these patients because of insomnia, they may relax their muscles, aggravate airway stenosis, and lead to more serious conditions.
