For people who are busy early in the morning, taking a nap in the afternoon, or taking a nap or taking a nap, can not only sweep away physical and mental fatigue, but also clear their thoughts and moods after waking up. Regarding its benefits, ancient Chinese medicine has a theory of "meridian sleep", that is, falling asleep at noon and noon every day, "sleeping at noon and taking a nap at noon". Its theoretical basis comes from Huangdi Neijing, an ancient Chinese medicine book, which says: "Exhaustion of Yang leads to lying, while exhaustion of Yin leads to tiredness." From 23: 00 p.m. to early morning 1, when the yin is the most abundant and the yang is the weakest; At noon, it is 1 1 to 13, when the yang is strong and the yin is weak. People resting at the peak of yang spirit is beneficial for the body to "harmony with yang" through qi, and also gives the body an opportunity to eliminate fatigue, nourish the heart and eyes, and protect the mind. There is a saying in Cao Tingdong's Old Heng Yan in the Qing Dynasty called "Taking a nap to help Yang".
In ancient times, the ancients studied sleep very well, and made clear "regulations" for every kind of deep sleep, shallow sleep or postural sleep, that is, sitting and dozing off, called "sleeping"; Closing your eyes and not falling asleep is called "sleeping"; Sleeping on a coffee table or desk is called "lying down"; Sleeping on the kang is called "sleeping"; Lie down and sleep, and when you fall asleep, it is called "sleep"; Just waking up, sleepy, called "sleep" or "sleep" There is an explanation in Xu Shen's Shuo Wen Jie Zi in the Eastern Han Dynasty: "Sleep, sit, sleep." Thus, there is "sleep", which is commonly known as "nap".
Biography of Historical Records of Shang Jun records: "Xiao Gong saw Wei Yang and had a long talk. Xiao Gong has been sleeping and listening. " The "sleep" here is "sitting and sleeping"-dozing off. Qin Ce, the Warring States Policy, records that Su Qin was "sleepy when he was studying, so he stabbed himself in the thigh and bled to the foot". Sleeping is also dozing off.
In the Song Dynasty, siesta showed a state of wanton leisure. For example, in the Song Dynasty, an official named Cai Que passed by a landscape when he was demoted to Anzhou. At noon, he decided to read a book and have a rest. After opening the book, he felt a little sleepy. Gradually, he threw the book aside and fell asleep. This is in his "Boarding to the Summer Pavilion", which has a "paper screen stone pillow bamboo square bed, and the hands are tired and the books are long." Similarly, there is Lu You's "The incense cloud at the bottom of the account is not scattered, and the book in his hand is silent." Wake up, it's all over; I fell asleep and let the book in my hand fall silently; Don't wake me up just because I'm sleepy, so as not to disturb my dream.
Of course, the ancients also paid attention to "enjoying the fun of taking a nap." Su Shunqin, a poet in the Song Dynasty, wrote in "Summer Meaning", "The farewell hospital is deep in Ming Xia, and the pomegranate is full of curtains. It's noon in the shade of trees all over the ground, and I dream of warblers. " The dense shade blocks the summer heat, and I lie on the bamboo mat, cool and refreshing; Pomegranate flowers are in full bloom outside the window, and the virtual hall is red through the hanging bamboo curtain. It was noon, and when I woke up, I heard Huang's intermittent singing, melodious, energetic and particularly comfortable.
In addition, there is an allusion about a nap, which comes from Liu Yiqing's Shi Shuo Xin Yu Liang Ya in the Southern Song Dynasty. The master sent a letter from his protege, Prime Minister Wang (Wang Dao), asking for a son-in-law. The prime minister sent a message:' you can go to the east wing and choose any one.' The protege returned to Bai and said, "All the Wangs' surnames can be praised. As soon as they heard they were looking for a husband, they were salty and reserved. Only Ichiro is lying on the east bed. If you haven't heard of it. Xi Gongyun: "Exactly!" It's easy to visit it because I married a woman. "Who is" Ichiro "? It was later the famous "book sage" Wang Xizhi. Wang Xizhi was informal all his life and was indifferent to his marriage. For his wanton nap, in Chi Jian's view, this man is open and unpretentious, and he will be a man in the future.
Later, after Wang Xizhi married Chi Jian's daughter, the husband and wife loved each other and never married other wives. Two * * * gave birth to seven children and a daughter, and they loved each other all their lives. From then on, everyone called the son-in-law "son-in-law"
Now that the hot summer has arrived, the excessive temperature makes people feel tired and depressed easily, so taking a nap at the right time, although the way is not as chic as the ancients, and the sleeping position is also various, its advantage is still what Bai Juyi said in "Sleeping at leisure". "Sleeping at leisure will eliminate all diseases." Take a nap, don't have a taste.
