Myth 1: Sleeping pills can be taken for a long time. The sleep that comes from sleeping pills is not a substitute for true natural sleep. This is due to the fact that more than 95 percent of hypnotics shorten deep sleep. Experts point out that so far no exogenous sleeping pills without toxic side effects have been found, and sleeping pills should be taken under the guidance of a doctor. Myth 2: Physical exercise is only good for insomnia. Physical exercise can be used as an adjunct therapy for insomnia patients, but do not exercise vigorously before bedtime, otherwise, the brain is easily excited and lead to insomnia. The elderly should not sleep back after morning exercise. Myth 3: The more sleep you get, the better for your health. Why the more I sleep, the more tired I am?” “If I don’t sleep tonight, I’ll make up for it tomorrow.” When such motives appear in your mind, experts warn that you have entered the sleep misconception. At present, some workers like to “catch up on sleep” in the double day off, but often later found in the double day off is not as good as the usual mental state. Experts think that the time of sleep is not much related to healthy sleep, everyone’s sleep time is not the same, individual differences, quality is more important than time, the most important thing is to maintain the regularity of life. Myth 4: Sleep disorders are not diseases. It is known that 8% of people have varying degrees of sleep disorders throughout their lives. Insomnia can be eliminated and poor sleep is different from neurological disorders. For a few people with sleep disorders, it may be a manifestation of some disease that has not yet manifested itself or has already appeared.

However, if the next day’s mental state is very good, you can not think not well rested. Myth 6: Drinking alcohol can hypnotize. In reality, there are many people who drink some wine before going to bed, thinking that this can quickly fall asleep, experts believe that this practice is not desirable. During sleep, the harmful substances in the wine accumulate in the body, poisoning the body, but also harm the retina, will make the body adapt to reduce. Myth 7: Sleep can store and prepay. If the advance is an extra-long period of wakefulness, then it is an overdraft of life. Sleep compensation afterwards can only relieve the exhaustion afterwards, but it cannot repay the mental and physical energy overdrawn in advance, and the resulting damage to the body. Myth 8: Daytime sleep is not needed. Daytime sleep is helpful to coordinate the physiological clock and 24-hour cycle. But daytime sleep should not be too long, to 15 minutes is appropriate. Studies have shown that daytime sleep can prevent premature aging and reduce the incidence of cardiovascular disease by 30 percent. But daytime sleep is not suitable for everyone, 20% overweight, low blood pressure, circulatory system suffering from serious disorders of disease, often due to daytime sleep caused by local blood supply to the brain and stroke.
