As the saying goes: 'The bed is against two walls, and the family suffers from illness.' Which two walls are you referring to? What is the reference value

China has thousands of years of long history and splendid culture. Our ancestors have accumulated a lot of life experience in practice and spread to today, a large part of which is spread to today in a concise, humorous and catchy way to guide people's production and life.

In ancient society, writing was in the hands of a few people. The literate population was only a small fraction, and book printing was much more efficient and costly than it is today. Therefore, ordinary people mainly transmit culture through word of mouth. Concise proverbs were created to facilitate word of mouth.

The wisdom and experience passed down by the ancients for thousands of years.

As the saying goes, if you don't listen to the old people, you will suffer losses in front of us. That is to say, the elderly have accumulated rich life experience through life practice and personal experience, which can provide us with life guidance and avoid detours in our future life. Over the course of thousands of years of Chinese history, our ancestors accumulated countless life experiences, many of which were conveyed in concise proverbs.

In ancient times, science had not yet formed such a strict system as it is today. It doesn't seem to be scientific and rational in today's sense. Even the life experiences contained in some proverbs are superstitious. In today's opinion, this is complete nonsense and has no scientific basis. However, there are also natural laws or experiences discovered by some ancient people through long-term production practice and life experience, or long-term observation, which still have important practical significance to us.

For example, the Chinese term for 24 suns is a good example of this. In the long-term life of our ancestors, by observing the changes of phenology and weather in a year, after the accumulation and experience of several generations, the concept of the time of the year was refined, and the year was further divided into four seasons: spring, Summer, autumn, winter. In fact, there were only two seasons in the beginning, so the classic to record history is called spring and autumn, which means to record what happened in the year. Later, time was further divided into 12 months and 24 solar terms. Summarizing the phenological changes of each solar term and guiding agricultural production and living arrangements, such as grain rain farming, summer scythe, and planting melons and beans before and after the Qingming Festival, are valuable experiences to guide farmers' production and life.

Similarly, there is a proverb passed down from generation to generation by the ancients, that the bed is against two walls and the family is sick. In general, there are two walls that cannot be leaned against the bed, and if this is done, the person sleeping in the bed will suffer from sickness. So, is there any scientific basis for this claim? Which two walls are these two walls?

The wall near the window.

The first wall is the wall near the window. There are some scientific reasons why the bed cannot be near the window. Due to the better lighting and ventilation near the window, many people like to place the bed near the window, and it is easy to see the outside scenery, but there are also certain health risks.

Although the windows are now well sealed, there is still a lot of dust coming through the windows or outside ventilation and adhering to the bed. It is easy for bacteria to multiply in the bed in the long run. Every spring blooming season, large numbers of pollen particles can enter a room through a window, and many people with pollen allergies can get caught.

Also, if you catch wind or rain, the humid outdoor air may also enter the room through the window and cause the bed to be damp. Especially in summer, because the windows are often opened for ventilation in summer, and the storms in summer are often sudden attacks, so the wind and rain often do not close the windows in time, so if the bed is close to the window, it will be more painful and more likely to be submerged.

When the weather is warm, many people like to sleep with the windows open, or forget to close the windows after falling asleep. If the bed is placed near the window, sleeping with the window open is easy to catch a cold, or even suffer a stroke due to a cold. Especially in ancient times, the window paper attached to the window was easily scratched due to the poor sealing of the window. This can be worse in the cold Northeast. Therefore, if the bed is near the window, there will indeed be various problems that will bring a lot of inconvenience to life.

Close to the wall of the kitchen.

The second wall is the wall near the kitchen. Chinese kitchens are very different from foreign kitchens, which is mainly caused by the different eating habits of China and the West. Chinese food is rich in cooking techniques, such as frying, so Chinese kitchens are relatively heavy with oil fumes. Especially in ancient times, or in many rural areas, the living habit of cooking with firewood was still maintained, so the kitchen often had smoke from firewood or coal. If the bed is close to the kitchen, oil fumes or various smells from the cooking process will spread to the bedroom and affect the indoor air quality. Small particles from heating may adhere to the bed, causing the bed to smell.

In addition, the kitchen often produces a lot of water vapor during the cooking process, and the environment is relatively humid, especially in ancient times, without a range hood, this situation will be more serious. If the bed is close to the kitchen, the diffusion of water vapor will cause the bedroom environment to be humid, prone to mold, bacteria and other problems, and will also cause harm to human health.

As for the second wall, many people think it refers not to the wall near the kitchen, but the wall near the bathroom. There is some truth to this, too, as bathrooms have poor sanitation and are also the easiest places to breed bacteria. In addition, bathroom odors are more difficult to eliminate, and the environment is relatively humid, so it is more likely to produce harmful bacteria. However, given the reality, I think as the saying goes, the second wall is more likely to be closer to the kitchen. Because in ancient times, in most rural areas, people's living space was separated from toilets, far away.

In ancient or rural areas, in rural areas. The toilet is usually outside, in a corner of the yard, and many people even put the toilet outside the door. Therefore, there is usually no bed near the wall near the toilet. So I think the second wall in this sentence refers to the wall near the kitchen.

Conclusion: Various proverbs are the wisdom of life summed up by people in different historical periods based on their life experiences. These proverbs depend on the specific era background and living environment. They change over time, not stay the same. Many proverbs passed down by the ancients can still provide a lot of useful help for our lives, but some have been out of the era we live in today and have no realistic guiding significance, which requires us to learn to screen in practice.
