Even children born in Lian Gang know that when they are sleepy, they have to sleep. But what we don't know is that sleeping is also a science, and there are many unknown pressures.

To this end, the ancestors also summed up a sentence: "Sleep without lying dead, sleep without going north." Is there any scientific reason for this statement of the ancients? This sentence embodies the knowledge of sleep health.

Nowadays, many people like to sleep late, especially in winter. It is human nature to long for a moment of pleasure, but if the sleeping time and posture are wrong, I am afraid it will have a negative impact on health.

First, sleeping position, not lying down to die.

From the superficial meaning of this proverb, it means lying like a corpse while sleeping. This sleeping position sounds terrible, so why is there such a statement?

Because in ancient society, life and death was an important event in life, or the concept of treating life as death was particularly strong, so if a person sleeps like a dead person, it is not only a threat to the living, but also a disrespect for the dead.

Of course, if this statement works from the etiquette point of view, it is also a feudal superstition. If you talk about a person's sleeping posture from the perspective of traditional Chinese medicine, sometimes it can also affect this person's health.

If you sleep on your back, it may lead to special fatigue and affect your respiratory function. You can't rest in this situation, which will affect your health over time.

At the same time, people who take this sleeping position often put their hands on their chests, which is easy to oppress their hearts and affect their breathing.

Most importantly, it will also cause great psychological pressure, and even feel palpitation after waking up. What people usually call "ghost pressing bed" is mostly because of this sleeping position.

Second, the direction of sleep, sleep is not the north.

After talking about sleeping position, we should talk about the direction of sleeping position that our ancestors paid attention to. In modern society, people don't pay so much attention to sleep because of the different housing patterns.

However, in ancient society, ancestors put forward many requirements for the direction of sleeping. For example, "sleeping north" is the most noteworthy place among many requirements.

Since ancient times, people like to face south when building houses. Besides the relationship with lighting and wind direction, the most important thing is that sleeping in such a house will be particularly comfortable.

In ancient society, people like to sleep with their heads facing south, which shows that they are basically sitting on a big kang facing south. This is because the wind in the north is particularly strong. Even if there are gables, there will be some cold air rushing into the room.

If you sleep with your head facing south and your feet facing north, you can avoid catching cold in your head and many unnecessary diseases.

Looking back, "I can't sleep, but I can't sleep in the north" actually talked a lot about the relationship between sleep and health.

There is also a saying that "don't cover your head with a quilt", that is, you can't cover your head with a quilt when you sleep, which will easily hinder your breathing and cause the air in the quilt to become turbid, which is obviously not good for your health.

Another is that in the society at that time, only people would "cover their heads" after death, which shows that this practice is also an unlucky omen. "Can't sleep in the north" comes from the old saying: "Don't lie in the north first, which means avoiding Yin Qi";

There is also a saying in "A Thousand Daughters Want a Party": "Don't lie with your head facing north, and don't sleep in the north of the wall." If we analyze this proverb from the perspective of modern medicine, it actually has a very scientific medical truth, which shows that sleeping is by no means a simple thing.

In life, many people get up in the morning, and if there are symptoms of stiff neck or fatigue, they will say that they didn't sleep well last night. It can be seen that sleep is closely related to their health and state.

So I'm here to advise you not to ignore the importance of sleep, or your body will be damaged sooner or later.

conclusion

In modern society, many young people pay special attention to sleep time and quality, and even stay up late to play games or work.

I don't know that long-term lack of sleep will lead to the decline of physical resistance, and it will also seriously affect the metabolism of internal organs, which will eventually lead to many incurable diseases.
