Myth #1: The longer you sleep, the healthier you are. The results of the study prove that people who sleep more than eight hours do not live longer than those who sleep six or seven hours. Scientists are still unclear whether more sleep makes health decline or whether more sleep is one of the symptoms of some disease. In fact, the length of sleep does not have much to do with healthy sleep, quality is more important than time, the most important thing is to develop good sleep habits. Myth 2: More dreams indicate a lack of sleep. People who have such a misconception will form a subjective feeling of fatigue once they have dreams. In fact, dreams are an ordinary physiological phenomenon, every normal person will dream during sleep, as long as the next day’s mental state is very good, you can not think that there is no good rest. Myth 3: Drinking alcohol can stimulate sleep. Some people think that some wine before bed will quickly fall asleep. This practice is not desirable. Drinking alcohol before bedtime does shorten the sleep latency period, but it also shortens the total sleep time. And the accumulation of harmful substances in alcohol in the body can damage health. Myth 4: Sleep can store and advance. Some people sleep very little because they are busy at work on weekdays, but sleep furiously on weekends, thinking that more sleep on weekends can make up for the lack of sleep on weekdays. I do not know that this will make the weekday sleep rhythm out of order, more difficult to restore normal sleep. Therefore, it is best to get up at the same time as usual on weekends. Myth #5: Sleeping pills can be taken often. The sleep brought by sleeping pills is not a substitute for real natural sleep, because sleeping pills shorten the duration of deep sleep. Most sleeping pills also carry the risk of long-term addiction, so sleeping pills should be taken under the guidance of a doctor. Myth #6: Reading in bed helps you sleep. Some people will engage in activities unrelated to sleep in bed (such as reading, reading newspapers, watching TV, etc.), and over time, it will lead to bed and sleep have no relationship, once the bed thinking instead began to be active, thus aggravating insomnia. Myth 7: Older people should get more rest. Although the elderly need sufficient sleep as much as the young, but as people grow older, the sleep time is shortening, the longest for babies and the shortest for the elderly. Therefore, do not cause anxiety because of the shortened sleep time, and then take sleeping pills blindly. The quality of sleep is based on whether the energy returns the next day, not on the total sleep time or total time in bed. Misconception eight: bad sleep also to lie down. This is to confuse the time spent in bed with the time spent sleeping. In reality, what we are concerned with is effective sleep time, not how long we lie in bed. If you find yourself with poor sleep effectiveness, instead of forcing yourself to lie in bed, you need to seek prompt professional help to improve sleep effectiveness.
