Have you ever heard the saying white dew poisons people, cold dew saves people ?

Heard. <>

There is a saying in the countryside that "white dew poisons people, and cold dew saves the world". Does this make sense?

Let's first talk about whether "white dew poisons people" is true.

September 7th is the white dew, at that time it was still the seventh month of the lunar calendar, just the beginning of autumn month, although there is coolness, the temperature is still a little high, mosquitoes are still a little rampant, but as long as the white dew, the arrogance of mosquitoes will gradually disappear, even if you listen to the buzzing around, it is not much to bite, what is the reason for this? Some people say that after drinking white dew water, mosquitoes can't open their mouths. This is a mistake in thinking that white dew water is poisonous and that mosquitoes gradually disappear because they drink white dew water.

In fact, this idea really overestimates the role of white dew, and the demise of mosquitoes has nothing to do with white dew, mainly because the weather is getting colder, which is not suitable for mosquitoes to survive. If white dew is really poisonous, then some animals such as cattle and sheep will also suffer from eating dewy grass? Including us humans also like to eat some vegetables with dew, because vegetables with dew appear fresher.

For example, people like to go into the vegetable garden and pick and eat cucumbers and tomatoes with dew, but after eating, they don't have stomach problems or any discomfort because of the dew. This alone is enough to prove thatThere is nothing bad about white dew water, it is not toxic to animals, and there is no need to worry about people.

Cold dew saves people, literally means that cold dew is very important and can save people.

Why is there such a big difference between "white dew hurts people, cold dew saves people"? In the past, people had this saying because they planted crops before and after the cold dew season, and the south was going to start planting wheat in this season, and if the rain was abundant at this time, it would naturally be a good thing for the crops, and the crops would be harvested and the farmers would not be hungry.

But in fact, this cold dew is not as magical as imagined, like the south sometimes many rural areas have heavy rainfall, more waterlogged, cold dew causes the rice to be rotten, there is no way to start harvesting, so it seems that the cold dew does not save people, but harms people.

Regardless of whether it is white dew or cold dew, good water is good water that can make crops grow well, otherwise it is "bad water" that is not conducive to crop harvest.

Every year on September 7 or 8, the temperature difference is the largest. The temperature difference between the day and night temperature may reach more than 10 degrees Celsius at most, and if you come into contact with water, the cold will enter the bone marrow, and you will get sick if you don't do it well. "Cold dew, savior" refers to the day of cold dew, that is, on October 7 or 8 every year, when the temperature is very low at night, the water vapor condenses at night, and the temperature rises during the day, turning into nectar to moisten the crops.

I've heard of it. Ancient people liked to use metaphors to cover meanings. This means that if the weather becomes cooler after the white dew, do not drink raw water, otherwise you will get sick easily. After the cold dew, many crops or fruit trees will mature after being moistened.

I've heard this saying, and I think it's a very profound saying.

I don't think the white dew here is just the dew after the solar terms, because no one will drink the dew. Some people explain that after the white dew, people can no longer drink cold water, no longer can take cold showers, I think this explanation is not quite correct, because whether there is white dew or not, people are not suitable for drinking cold water, drinking cold water in any season has the possibility of stomach trouble. My understanding is that white dew water is like arsenic, generally refers to the rain before and after the white dew, as soon as the white dew solar term arrives, it is the season of harvesting peanuts in our Jiaodong area, if the rain continues in this season, you can imagine how much harm to farmers.

After the summer, many crops have begun to mature, especially peanuts, as long as the summer heat, the leaves will gradually wither yellow, during which peanuts do not want to rain. Because as soon as the white dew arrives, the peanuts will be harvested, and at this time, if there is a lot of rain, the peanut vines will dry up. In the past when mechanization was not developed, peanuts had no vines, and farmers had to pay several times the time to harvest peanuts, which was laborious and laborious, which brought great trouble to the autumn harvest.

If the family has few people and it is too late to snatch the peanuts back home, the peanuts left in the field will soon sprout again due to too much rain in the field.

Rain is indispensable for crops, but it really depends on the time and solar terms, and if the next solar term is not right, it is poison. If the rain continues now, it will cause the peanuts to germinate twice, which proves that all the peanuts in hand are wasted. Once the peanut sprouts, not only does it lose the value of oil extraction, but it will also be bad for the body if eaten.

Therefore, farmers who grow peanuts are especially afraid of the rain before and after the white dew, and the rain at this time is really tantamount to poison for farmers.

In the past few days, we have been raining non-stop here, changing the drought situation of previous years, the rain the night before yesterday until noon yesterday, and the rain in some places has flooded the car, which is the biggest rain this year. The old people in the village all said that if it was summer, it would have rained so heavily, but now it is autumn, and when it comes to the autumn harvest season, it will rain so heavily, peanuts should be careful. Many people say that there has not been such a big autumn rain for many years.

I checked the weather forecast, fortunately, the weather has been sunny and no rain in the last few days, if it rains again, then the peanuts are really unlucky.

It is really poisonous, and after the weather becomes colder and colder, many water molecules in the air will turn into dew after encountering cold air, and then it will also cause excessive cold in the human body.

This is because one of the 24 solar terms in our country is white dew, and many insects will gradually die after the white dew solar term, so there is such a saying that white dew water is not poisonous.

This is just a folk saying, because by the time of the white dew, the vitality of many insects is not so vigorous, so the old people in the countryside think that it is caused by the white dew.

It means not getting cold, not using cold water, and staying away from cold water during this season. White dew is not poisonous, but the dew is very cold and easy to get sick.

This means that the toxicity of white dew water is very strong, and it can even kill a person. White dew water is indeed very poisonous because there are so many toxins in it.

It means that before the arrival of white dew, the temperature difference is relatively large, and it is easy to make people sick, and on the day of cold dew, the temperature is low at night, and the water vapor condenses at night, and the temperature rises during the day, turning into nectar, which can moisten crops, and this sentence contains the wisdom of the ancient Chinese working people.

This means that the white dew in the morning may be combined with the haze, so it is possible to poison people, but if it is the season of Xiaohan, then this dew can be used as medicine.

It refers to people who may be poisoned if it is dew during the day, because it is highly poisonous, and if it is at night, it can have the effect of curing all diseases.

What does the phrase "white dew poison people" mean, and how to understand it?

The ancients said, "On the September Festival, the dew is cold and will condense." "The temperature is lower in the cold dew than in the white dew, and the dew on the ground is colder, and the morning dew is about to condense into frost. As soon as the cold dew passes, the vast area north of the Nanling Mountains in China will enter autumn, and the northeast and northwest regions will soon enter winter.

In ancient times, the 24 solar terms were very important, because this was an important means used by the ancients to predict the weather, and the ancients summarized some of the functions of the solar terms with some direct and catchy proverbs, so that it was convenient to circulate, which was actually very reasonable. Just like the phrase "white dew poisons people, cold dew saves the world", it is a smooth slip formed through people's life and practical experience. White dew, a day when the climate temperature difference changes greatly, is also a node from warm to cool.

So there is a saying "After drinking white dew water, mosquitoes shut their mouths". But do mosquitoes really stop biting after the white dew? In fact, it shows that the weather has cooled.

After the white dew, the temperature gradually decreases, and it is no longer suitable for mosquitoes to breed offspring, so mosquitoes will not reproduce anymore, and the number will slowly decrease, so there are basically no mosquitoes coming out to bite.

There is also a meaning: after the white dew, the autumn is cool, do not drink raw water casually, and use hot water in the bath, otherwise it is easy to catch a cold, which is to advise people to pay attention to body maintenance. The ancients liked to use metaphors to talk about things, and this kind of exaggerated rhetoric achieved the effect of metaphor and reasoning, and the effect was also good.

And "cold dew, save the world", refers to the night frost on the day of cold dew, early morning dew, after the cold dew water, many crops and fruits can ripen. This is based on science, the fall of frost and dew will precipitate the organic matter in the plant, the sugar is transformed, after the cold dew, not only can harvest the fruit, and the taste is also excellent, the plants are a mature scene, the leaves have turned red, the chrysanthemums are yellow, and we can see the scene of the autumn harvest after the cold dew.

The people take food as the sky, for the ancients, there is nothing more important than the harvest, everyone is looking forward to the arrival of the cold dew, all hope to have a good harvest to feed the family, and reserve food for the winter, and then there is the cold dew, the saying of saving the world. In ancient times in our country, the cold dew was divided into three waits: "one is the guest of the wild goose; Second, the finch enters the water as a clam; Sanhou chrysanthemum has yellow flowers.

On this day of cold dew, we can often see the wild geese lining up in a line or herringbone to move south. In late autumn, it was much colder, and the birds were gone, and when they saw a lot of clams suddenly appearing on the beach, and the stripes and colors of the shells were very similar to those of the birds, people thought that the birds had become. The third candidate "chrysanthemum first yellow flower" is relatively simple, which means that chrysanthemums have generally bloomed on the day of cold dew.

The ancients used dew as a sign that the weather was getting cooler. In late autumn and winter, it is already the season when the dew is cold and condenses into frost. In the cold season, the temperature gradually turns cold, and we must do a good job of keeping warm to avoid contracting the wind chill.

At the same time, you can enjoy the beautiful late autumn scenery, such as the golden Yinxing, the fiery red maple leaves, and the blue sky, these are all scenery that can make you feel comfortable!

Because some plants contain toxins, the dew is formed by the condensation of the air, and there is dust inside. The combination of the two is harmful to the human body.

The ancients believed that it was because they drank "white dew water" that mosquitoes were poisoned to death, so that they believed that white dew water poisoned people, which is obviously a wrong understanding. The main reason is that the weather is cold, and people's lives are affected. And why can cold dew save people?

In fact, around this solar term is the wheat planting season, if there is rain at this time, it must be a good thing, so that the wheat seedlings can take root quickly, so that there is a higher harvest, and its yield will also increase.

This means that dew with a white color is highly poisonous. Because the white dew may be formed after the dew absorbs the poisonous gases in the air. So toxic.
