Insomnia is a condition of dissatisfaction with the quality and quantity of sleep that persists for a considerable period of time. The length of sleep cannot be used as a criterion to judge the severity of insomnia. Anxiety and fear of insomnia can form a vicious circle, which leads to the persistence of symptoms. Patients may have difficulty in falling asleep, lack of deep sleep, wake up easily, feel dreamy, wake up early, wake up easily, feel tired or lack of wakefulness after waking up, and feel sleepy during the day. Patients often feel anxious and fearful about insomnia, and in serious cases, it can also affect their mental efficiency or social function. Causes of insomnia 1, acute stress: mental tension, recent loss of life, physical discomfort, sleep environment change, jet lag reaction, etc. Drug-induced insomnia: Caffeine, theophylline, thyroxine, cocaine, corticosteroids, antitremorine paralysis drugs, adrenaline-like drugs. 2, psychogenic insomnia: often due to excessive concern about their difficulty in falling asleep, worry, to overthinking, excitement or anxiety annoyance. In their attempts to fall asleep or continue to sleep again corresponding frustration, anger and anxiety make them more awake so that it is difficult to fall asleep. 3, insomnia caused by mental illness: early awakening due to depression, mania due to day and night excitement and restlessness with little or no sleep. The diagnosis of insomnia must exclude various physical diseases (peripheral neuritis, myelopathy, rheumatoid arthritis, malignant tumor) or symptoms accompanying other mental diseases (difficulty in falling asleep common in anxiety disorders, early awakening common in depression). Whether it is insomnia or not, it needs to be analyzed by a specialist according to the specific situation of each patient. In the face of insomnia, I would like to talk to you about: 1, the correct understanding of sleep: the pursuit of sleep quality, not time, sleep time varies from person to person, and different ages, sufficient sleep is not seen from the number of hours, but depending on whether mental and physical recovery as the standard, adults generally maintain 7 to 8 hours can be, depending on individual differences. 2, optimize the sleep environment: the most appropriate sleep environment should at least have the appropriate temperature (15 to 24 degrees), quiet (if the outdoor noise, then close the doors and windows to sleep), blackout (with thick curtains or blinds to isolate the outdoor light), comfortable (comfortable, reasonable bedding), etc. can improve the quality of sleep. 3, optimize sleep habits: first of all, do not lie in bed reading books, newspapers, or talk about some exciting topics, will weaken the direct link between the bed and sleep. Let the bed play a single sleep function will be able to form a conditioned reflex, to achieve the effect of falling asleep once the head next to the pillow. Secondly, no matter how long or how short sleep, please get up at the same time every day, then the biological clock will run on time, which is one of the keys to improve the quality of sleep. Again, conditions allow, you can nap to reduce the stress of life, to help sleep at night, but should not exceed half an hour. Finally, 4, ready for sleep: do some activities to relax your body and mind before bed, such as a hot bath, foot dipping before bed, meditation, listen to soft lyrical soft music. Before going to bed avoid eating, drinking stimulating drinks, excessive emotional excitement, excessive entertainment and talk, to ensure that the mood is smooth and comfortable. 5, the use of appropriate sleeping position: for a healthy person, the best position for sleep should be the right side of the position or flat position, which will not compress the heart, but also facilitate the relaxation of the limbs of the body rest. Sleep is best not to use the left side position, affecting the heart; supine sleep, hands should not be placed on the chest body to avoid heart compression and nightmares. However, for patients, the best position for sleep depends on the patient’s condition and type of disease. 6, pay attention to eating habits: do not eat too much for dinner, or go to bed on an empty stomach. Eat more zinc and copper-rich oysters, fish, lean meat, shrimp, eel, yellow cabbage and other foods at dinner; consider eating some tomatoes, bananas, walnuts, apples, red dates, millet, oats, sweet corn, steamed buns, bread, etc., and eat less chocolate, cheese, coffee, cola and tea; before going to bed, eat some dairy products or drink a glass of milk to help you sleep. Before going to bed, avoid drinking a lot of alcoholic beverages such as beer, they can prompt people to fall asleep, but will affect the quality of sleep. In addition, coffee, tea, cola drinks and chocolate and other caffeine-containing beverages on the human brain nerves can produce excitement, it is best not to drink before bedtime. 7, regular aerobic exercise: aerobic exercise can relieve the tension accumulated during the day and make the body and mind relax and improve sleep. At least 3 days / week, 20 to 30 minutes / time of walking, tai chi, yoga, swimming or cycling. The ideal time to exercise is late afternoon or early evening. If you are still unable to get the desired quality of sleep after adjusting yourself in many ways, and it affects your mental state during the day, you can seek help from a psychosomatic physician or neurologist and use insomnia medication under the guidance of a physician to improve your sleep for a short period of time to avoid delaying your condition.
