"xuanmian floating clouds never think about it, and the three peaks only beg to sleep for a thousand years." this is the answer of chen tuan, a famous taoist scholar and health expert in the northern song dynasty, when he was recruited by zhao guangyi, emperor taizong of the song dynasty, on his way of maintaining health. according to the records in the biography of chen tuan in the history of song dynasty, chen tuan can sleep for more than 100 days, so he has the reputation of "sleeping fairy". in fact, chen tuan did not simply sleep, but regarded sleep as a means of self-cultivation and health preservation. therefore, he lived a long life of 118 years.
the ancients were very particular about the way to sleep. as early as the yellow emperor's canon of internal medicine, there were records on how to sleep more healthily, and its su wen chapter was the "guiding document" at that time. among them, the great theory of four qi regulating spirit pointed out that the time to go to bed was not invariable, but should change according to time: in spring and summer, you should "lie down at night and get up early", and in autumn "lie down early and get up early" and "lie down early and get up late" in winter. this "sleeping principle" is of reference value even in modern times with a fast pace of life.
indeed, one third of one's life is spent in bed and sleep. it can be seen how important sleep is to one's health. the quality of sleep will directly affect our brain thinking, human growth and development and immunity. with a little negligence, sleep will even become "the man behind the curtain" of various diseases. but for busy modern people, high-quality sleep has become an extravagant hope. according to the data released by the world health organization, nearly a quarter of the world's people suffer from insomnia, nearly 860 million people suffer from insomnia depression disorder every year, and 75 million in china alone.
