After entering the 21st century, people’s health awareness has rapidly increased, and the new concept of “having health is having everything” is deeply rooted in people’s hearts. Among the many health hazards, insomnia is a commonly occurring and easily neglected disease. Sleep is a basic need of people, and one third of each person’s life is spent in sleep. Good sleep can eliminate fatigue and restore physical and mental functions. In 2004, the detection rate of poor sleep quality in Hebei province was 11.6% for residents over 18 years old. What kind of insomnia will become a problem? 1, the standard of good sleep Good sleep needs to have the appropriate sleep length and sleep depth. Too short sleep is not good, and too long sleep is not good either. Generally speaking, adults need an average of 6-8 hours of sleep per day, special groups, such as long sleepers, may need 9-10 hours, and short sleepers, 5 hours is enough. Of course, sleep time is also affected by age, an infant, almost all day sleep; a toddler, need to sleep more than 10 hours a day; into adulthood is basically the average level. According to the literature, a 70-year-old nurse in the United Kingdom, who had slept little since childhood, was measured by researchers for seven consecutive days and confirmed that her daily sleep time averaged 67 minutes. The EEG during sleep can be divided into two types, one is called “fast eye movement phase” and the other is called “slow eye movement phase”. In the “slow eye movement phase”, there are often sleep waves, when people are in a deep sleep state. Each sleep is spent in alternating cycles of REM and REM, usually about 4 to 6 cycles per night. Waking up in the “fast eye movement phase” will feel like dreaming. To have a correct understanding of dreams, everyone will dream, dreaming is not only a normal psychological phenomenon, but also a way of working of the brain. Dreams themselves are not harmful to the human body, so there is no need to have a psychological burden for this. Therefore, dreaming is not a sign of poor sleep. The easiest way to judge whether you have a good night’s sleep is based on your following feelings. If you wake up every morning and are satisfied with your night sleep, if you wake up with a clear mind, if you have recovered your strength and energy, and if you are full of confidence in the face of the new day. If the answer is yes, it means that last night’s sleep was perfect. 2, how to determine their own insomnia Insomnia simply means that you are not satisfied with your sleep under the conditions of having sleep. The following conditions need to be met. First, you yourself feel very painful about insomnia; second, your work, study, daily life and interpersonal interactions are seriously affected; third, it occurs frequently, at least three nights a week and lasts at least a month. Short-term insomnia is not a disease. Everyone has the experience of insomnia, and when you encounter a great joy or a difficult problem, insomnia is a normal reaction and there is no need to worry about it. When the mood calms down, insomnia will naturally pass. Insomnia is manifested in the following aspects: difficulty in falling asleep, lying in bed, tossing and turning, unable to sleep; easy to wake up in the middle, sleep is not well maintained, sleeping and waking up; waking up early, waking up earlier than usual, waking up and never being able to fall asleep again; lack of sleep sense, although others observed that he slept well, medical examination also confirmed that he slept well, but he himself felt that he did not sleep well, very painful. 3, the adjustment of insomnia First, the correct understanding. People who have insomnia should first have a correct understanding of insomnia, a short period of insomnia does not have a serious impact on a person’s physiological and psychological functions. Many people who suffer from insomnia are nervous and anxious during the day because they are worried that insomnia will damage their health, and they are eager to fall asleep as soon as possible at night to have a good sleep, and as a result, they are unable to sleep once they go to bed. This worry and fear of sleep again becomes the cause of insomnia. Second, form good sleep habits. Respect the natural rhythm and try to fall asleep at night and wake up during the day. Stay quiet before bedtime and avoid overly exciting entertainment. If you encounter these exciting things, then after things are over, do not immediately lie in bed, you can sit quietly for a while, flip through newspapers and magazines, or take a bath or soak your feet in hot water until you feel nervous, your body slowly calms down, and then go to bed to rest. Create a comfortable resting environment, control the light, sound and temperature of the bedroom. Finally, we should match meals reasonably, avoid overfullness and hunger, and eat foods that are not digestible and stimulating can affect sleep. Thirdly, carry out medication. Insomnia medication must be reasonably applied under the guidance of a doctor, and different drugs should be chosen according to different situations to avoid dependence and withdrawal reactions. Commonly used drugs include benzodiazepines, non-benzodiazepines, azaperone and antidepressants.
