1. Sleep is an absolute need that must be met in every person’s life. The physiological importance of sleep is second only to breathing and heartbeat. Sleep accounts for 1/3 of a person’s life. Adequate sleep, balanced diet and proper exercise are the three health standards recognized by the international community. However, there is a general lack of awareness of the importance of sleep. In 2001, the Global Sleep and Health Program, sponsored by the International Foundation for Mental Health and Neuroscience, launched a global campaign to designate March 21 each year as World Sleep Day. The focus of the campaign is to draw attention to the importance of sleep and the quality of sleep. The need for sleep is not the same for different people. It is related to many factors such as a person’s age, personality, health condition, working environment, labor intensity, etc. It is also related to each person’s sleep habits.” (The length of the need for sleep at different ages: normal people generally sleep for about 8 hours a day, and as they grow older, their sleep needs are shortened. In general, the human body’s sleep requirement is 7 hours-9 hours a night for young adults, 1 hour-3 hours more for children and adolescents, and 1 hour-3 hours less for the elderly). 4, the concept of insomnia, the causes, the impact on the organism. Sleep disorders classification: insomnia, episodic sleeping sickness, post-traumatic hypersomnia, restless legs syndrome, sleep apnea syndrome, nightmares. Insomnia is a disorder in the initiation and maintenance of sleep, resulting in the quality and quantity of sleep not meeting the physiological needs of the individual, causing a series of mental and physical symptoms. Healthy people can tolerate hunger for up to 3 weeks, and if they do not sleep for 4 consecutive days and nights, it will cause irreversible damage to brain function. According to the World Health Organization survey, 27% of people have sleep problems, and the incidence of insomnia among Chinese adults is about 38.2%. Causes: The fast pace of life in modern society, high stress, as well as nightlife, alcohol consumption and other bad habits, various diseases of the body can trigger sleep disorders. They are summarized as periodic rhythm changes, behavioral disorders, environmental factors, other sleep disorders, allergic sleep, menstruation and pregnancy, drug use and abuse, but the most common are insomnia co-morbid with medical, neurological and psychiatric diseases. Impact on the body: Medical research shows that human sleep is directly related to the quality of human existence and quality of life. Long-term sleep disorders will lead to disorders of human physiological functions. The impact of insomnia is multifaceted, and the degree of impact is related to the severity and duration of insomnia. Mild or episodic transient insomnia does not have a significant impact on work or school. Sleep that lasts more than two or three days below the physiological need can have an immediate and noticeable impact due to the physiological need to catch up on sleep. The first to be affected are attention, concentration, fine motor skills, higher intellectual thinking and memory, and a significant decrease in learning efficiency and creative thinking. A significant number of patients with high blood pressure and heart disease are caused by poor sleep. Sleep deprivation will make the body immune system decline, low ability to fight and recover from diseases, easy to catch a cold, and aggravate other diseases or induce the onset of existing diseases, such as cardiovascular, cerebrovascular, hypertension and other diseases. It has been proven that patients who do not sleep well after surgery will take significantly longer to heal their wounds. Children who suffer from severe sleep deprivation can affect their physical development. Because during sleep, especially during the deep sleep period, children secrete the most growth hormone in their brains, which is the main substance to promote the growth of children’s bones. According to statistics: 45% of traffic accidents and 55% of workplace accidents in the United States are related to insomnia; according to conservative estimates: the annual economic losses caused by insomnia in the United States amount to $30-35 billion in terms of decreased production, sick leave, accidental injuries and concurrent diseases; the Gallup poll conducted by the American Sleep Foundation shows that half of the population has had insomnia, of which Many of them are chronic insomniacs; 60% of the elderly in the British survey nursing homes believe that sleep disorders are the biggest problem that plagues them; a questionnaire survey for college students in China shows that: poor sleep quality is as high as 48.9%, this figure will be much higher in the elderly. 5, the eight myths of sleep: Myth 1: The more sleep the better for health. Myth 2: Dreaming at night indicates that you are not well rested. Myth 3: Drinking alcohol can stimulate sleep. Myth 4: Sleep stores and prepares. Myth 5: Sleep disorders are not diseases. Myth 6: Naps are not needed. Myth 7: Sleeping pills can be taken for a long time. Myth VIII: Physical exercise is only good for insomnia. 6, sleep patterns: human sleep also has good and bad quality, the key lies in whether the sleep is scientific and reasonable. Get into bed within half an hour that can fall asleep, less waking up throughout the night; no dream or less dream; deep sleep, which is the requirement for the quality of sleep. Regulation 1: Sleep time Four seasons of sleep in spring and summer should “sleep late and get up early”, autumn should “sleep early and get up early”, winter should “sleep early and get up late”. It is best to get up before sunrise, not too late. The second rule: the direction of sleep sleep to head north feet south. The human body is affected by the earth’s magnetic field at all times, and the brain is also disturbed by the magnetic field in the process of sleep. When people sleep to take the head north feet south posture, so that the magnetic lines of force smoothly through the body to minimize the interference of the Earth’s magnetic field. Rule three: sleeping posture body sleep like a bow effect is good, to the right side of the burden is light. Research shows that “sleep like a bow” can be just right to reduce the force of the earth’s core on the human body. As the human heart is mostly on the left side of the body, lying on the right side can reduce the pressure on the heart, while hands to avoid being placed near the heart, to avoid waking up because of nightmares. Regulation four: sleep time period Whether it is “night owl type” people or “early to bed and late to rise type” people, should find their biological clock to improve the efficiency of sleep and rest. The best time period for human sleep should be 10:00 p.m. – 6:00 a.m., slightly earlier for the elderly 9:00 p.m. – 5:00 a.m., 8:00 p.m. – 6:00 a.m. for children. Rule 5: Sleep environment In the bedroom should try to avoid placing too many electrical appliances to ensure that the human brain rest without too much interference. In addition, do not wear “table”, “teeth” and cell phones and other items to sleep, otherwise it will affect the health of the body. 7, insomnia treatment Insomnia treatment is divided into two categories: ① non-drug treatment: good sleep hygiene habits – a regular rest time, a good rest environment, no strenuous exercise before bed, no tea, coffee, no smoking, to ensure that on time, sleep at ease; ② drug treatment: “on-demand treatment” and The treatment principle of “small dose intermittent” use of sedative and hypnotic drugs. Snoring is a very common condition, and the snoring of obese people is three times that of normal people; alcoholic beverages, psychostimulants, hypnotics and antihistamines can aggravate snoring. A detailed examination of nasal cavity, mouth, soft palate, throat and neck should be done for severe snoring. Sleep apnea syndrome has ≥10 seconds per pause, usually >30 times per night, and laboratory tests can measure a decrease in blood oxygenation. The ultimate evil of sleep apnea syndrome (SAS) is the development of cardiovascular and cerebrovascular disease, which should be treated with aggressive diagnosis.
