As the saying goes: you can't sleep with your feet facing west and your head facing east. Is it a superstition or a scientific basis?

About one-third of the human body, about one-third of the time is spent in sleep. A good night's sleep helps restore energy. But if you don't sleep well and are depressed, your life and study will be affected. Long-term insomnia can also lead to decreased immunity, making it easier to catch colds and get sick. Therefore, sleep is crucial to human health.

People pay a lot of attention to sleep. For example, when sleeping, you should choose a pillow with the right height and moderate hardness. A quilt with the right thickness, a moderately suitable environment, and so on. These all have a great impact on sleep. There is also a folk saying: You can't sleep with your head facing west and your feet facing east. When questioned, people always say: the words of the ancestors must be reliable, how can they be superstitious?

Today I will talk about sleeping with your head facing west and your feet facing east. Is there any scientific evidence? Is it superstition?

From a Chinese medicine perspective, this makes sense. Sleep orientation has an impact on a person's sleep. Sun Simiao, the king of traditional Chinese medicine, mentioned in "A Thousand Golden Prescriptions": "Scattered immortals lie down, eastward in spring and summer, and westward in autumn and winter." It means spring and summer, when you sleep, your head faces east and your feet face northwest. In autumn and winter, the head faces west and the feet face east.

This is because spring and summer are yang, and autumn and winter are yin. Qi and blood are abundant in spring and summer, while Qi and blood are restrained and latent in autumn and winter. The sleeping position should conform to qi and blood, and conform to the principle of nourishing yang in spring and summer and nourishing yin in autumn and winter in traditional Chinese medicine. In an ancient setting, this argument makes sense.

From a scientific point of view, there is a certain basis for sleeping with your head facing west and your feet facing east. The main reason is that the earth is a large electromagnetic field, and the north and south poles are the management centers, which are magnetic. In this large magnetic field, the body is affected by it.

If you sleep with your head facing west and your feet facing east, it does not conform to the direction of the geomagnetic field. The north-south sleeping position can scientifically regulate tissue cells and physiological functions. Sleep better and sleep better. This is the effect of body magnetization. Although the sleeping position in the east-west direction has little effect on health. But body cells are disturbed to some degree. Some people become anxious and have trouble sleeping.

In addition, China is located in the northern part of the earth, and the houses generally face north and south, and the sun faces the south, which is conducive to the growth of yang. So sleeping north and south is good for your health. However, it is not easy to receive sunlight in time. In this environment, sleep quality improves long-term.

To sum up, it is reasonable for the ancestors to say that you should not sleep with your head facing west and your feet facing east.

If you want to sleep well, you must not only pay attention to the direction of sleep, but also do three things well.

Don't sulk before bed. Many women sulk over a trifle before bed. Sleeping with negative emotions is bad for your health. When you are angry, the flow of Qi and blood will slow down, which will easily lead to hypoxia. When angry, the heart beats faster, which can easily lead to abnormal shortness of breath and affect normal sleep. Therefore, try not to be angry before going to bed. Solve any problems promptly and don't fall asleep angry.

Don't watch scary movies and TV shows before going to bed. Before bed, if you continue to look at your phone, browse horrible content. Exciting pictures, scary atmosphere affect the brain nerves. Nerves become tense, which can easily lead to insomnia. Watching exciting content before bed can also be prone to nightmares. In addition, playing with mobile phones before going to bed can also damage your eyes.

Don't drink too much water before going to bed. Drinking a lot of water can easily lead to frequent nocturia and affect sleep.
