From the holistic view of "the correspondence between man and nature", the orientation of sleep also has an impact on people's sleep and health. Modern science believes that the earth is a big magnet with north and south poles, and the human body itself is also a small magnetic field with magnetism and polarity. The big magnetic field of the earth always acts on the small magnetic field of the human body. Sun Simiao, a famous doctor in the Tang Dynasty, wrote in "A Thousand Daughters Should Be Prescribed?" Tao Lin cultivated his nature and said, "mortals lie down, facing east in spring and summer, and facing west in autumn and winter." In other words, the orientation of sleep is in spring and summer, with the head facing east and feet facing west; In autumn and winter, it is advisable to lie with your head facing west and your feet facing east instead of lying with your head facing north. The ancients' ideas do have some scientific truth.

From the seasonal point of view, spring and summer belong to yang, autumn and winter belong to yin; Azimuth, the east belongs to Yang, and the west belongs to Yin. Spring and summer are full of yang, autumn and winter are full of yang and yin. Therefore, lying with the head facing east in spring and summer conforms to the yang, and lying with the head facing west in autumn and winter conforms to the health-keeping principle of "nourishing yang in spring and summer and nourishing yin in autumn and winter" in traditional Chinese medicine, and is also conducive to healthy sleep.

In terms of the orientation of sleep, some ancient health experts also advocated lying in the east all the year round, thinking that the sun's yang rises in the east and lies in the east at the beginning of the four seasons to conform to the sun's yang rising in the east. In ancient times, some doctors and health experts believed that the direction of lying position should change with the seasons, with the change of spring, summer, autumn and winter, and the head should face east, south, west and north, which is also in line with the laws of nature and has certain scientific reasons. However, from the perspective of many health practitioners, it is best to take an east-west position.
