As the saying goes, "a person spends at least one-third of his life in bed", which also illustrates the importance of sleep to human beings.

In sleep, it can make the human body get enough rest, and it can also help the human body repair the aging of organs in the body, but now people's sleep quality is getting worse and worse, and many people cannot have a good sleep, which has also caused a lot of impact on health.

The ancients believed that sleeping is a way to maintain health, they pay great attention to sleep, there is a lot of research on sleep, such as the old saying "the bed against two walls, the home is sick", what does this sentence mean?

What does the old saying mean that "the bed is against two walls, and the home suffers from illness"?

The two walls mentioned here do not mean that the bed cannot be against two walls at the same time, but that there are two walls that cannot be relied on when the bed is set, and these two walls are the wall by the window and the wall by the toilet.

The ancients believed that when the bed was near the window, especially when sleeping at night, the windows at that time were ventilated, the temperature outside was lower than the temperature in the room, the body was more fragile in the sleeping state, and the wind and cold and wet evil were easy to take advantage of.

If the body is cold, then there will be a cold, so the ancients will not place the bed on the wall by the window.

Let's talk about why the bed can't be placed on the wall next to the toilet, because of the structure of the ancient people's houses, the toilet and the pigsty are connected to the house, the toilet and the pigsty are relatively dark and damp, and the humidity is very heavy.

At night, the body is more fragile when sleeping, do not sleep in a place with heavy humidity, otherwise the body will be damaged and suffer from wetness, so the ancients did not recommend placing the bed on the wall next to the toilet.

When people sleep three nights, their lives are thinner than paper, what does it mean? Does it make sense?

These three senses refer to laziness, post-meal sleep, and upside down.

Laziness

Generally speaking, from 11 p.m. to 6 a.m. on the second day is the golden 7 hours of sleep, and the sleep time is too long, beyond the normal wake-up time, then it is sleeping.

On weekends, it is easy to sleep late, but a sudden change in work and rest will cause the body's biological clock to be disturbed, hormones are imbalanced, headaches will occur after getting up, and poor mood will occur.

Sleeping lazily can easily affect the eating time, so that its disorder will also adversely affect gastrointestinal function, and even cause gastritis, indigestion and other diseases.

Sleep after a meal

Sleeping immediately after eating is a very hurtful sleep mode, which is easy to cause gastroesophageal reflux and induce reflux esophagitis, because the food has not yet come to digest and go to sleep, and the digestion rate of food will become slower, which can easily lead to food accumulation in the stomach.

Increase the burden on the stomach, induce gastritis, gastric ulcers, dyspepsia and other stomach diseases, so lunch interval 30 minutes, dinner interval three hours before falling asleep.

Upside down

Inverted sleep is the inversion of day and night, do not sleep at night and sleep during the day, long-term maintenance of this sleep mode will cause harm to the body, such as the inverted hormones in the human body's organisms, secretion imbalances, induced nervous disorders, decreased attention, slow response and other conditions.

It can also lead to endocrine system disorders, insulin secretion disorders, induce diabetes, and people who work night shifts to ensure adequate sleep time and sleep quality during the day can reduce the adverse effects on the body.

In short, sleep is very important to the human body, have a high quality of sleep, the impact on health and longevity is very large, want to have high quality sleep is also very simple, maintain regular and fixed sleep habits, stay stable before going to bed, etc., the practice is not difficult, but you insist, I hope you can remember.
