Is the well water in villages and towns alkaline? What is the temperature of the well water?

Lead: Especially in rural areas, there are well water in many places. Well water can't be drunk directly; it can't be drunk until it is boiled. Some friends are interested in well water. Then, Bian Xiao would say, What's the temperature of the well water? Is the well water in the village alkaline? Let's have a look.

What is the temperature of the well water?

Well water temperature is generally around 3.98℃ (commonly known as 4℃). The change of well water temperature "warm in winter and cool in summer" is actually based on its unique environment, because the well is underground, and the surface temperature is relatively low in winter, but the water in the well is deep underground, and the cold air on the surface cannot penetrate into the ground, so the well water located underground will be warmer than the surface temperature.

It is very hot outside in summer, and the heat on the surface is mainly due to sunlight, so the temperature is very high. But in deep well water, sunlight can't affect the stratum, so well water in summer will be very cold compared with hot weather.

Brief introduction of well water

Well water has nourished countless Chinese sons and daughters for thousands of years and created a glorious chapter of the Chinese nation. Drinking more water from the well can clear away heat and detoxify, which is beneficial to red-hot urine, unsmooth astringency and drunkenness. Besides, if there is no discomfort, drinking more water will also be good for your health. Drinking it all the year round is good for physical and mental health, and making tea is especially sweet and mellow.

Well water is sweet and non-toxic, and the ancients often used it to stop bleeding. Such as gold sore bleeding, dog bite bleeding and nosebleed, are all washed with well water. In addition, nausea, heat dysentery, heat shower, etc. It can also be treated with well water or boiled with well water.

Compared with the ground temperature at that time, people felt that the well water was warm in winter and cool in summer. In hot summer, the earth's surface is directly affected by the sun's irradiation and airflow, and the temperature rises rapidly.

Underground soil can only absorb heat from the atmosphere through the upper soil. Because of the slow heat transfer in soil, the temperature in the deep underground is lower than that in the ground, so the temperature in well water is lower than that in the ground. If the well water is lifted to the ground, it will feel particularly cold.

Is the well water in villages and towns alkaline?

Well water is alkaline water. The PH value of well water is alkaline, with a certain hardness and a certain amount of dissolved solids. This kind of water can not only be well absorbed by the human body, but also prevent the human body from absorbing toxic and harmful substances.

In addition, don't drink the same type of water for a long time, especially pure water. People of different ages should drink water with different mineral contents. For example, water containing metasilicate is good for the cardiovascular system of the elderly, but it is not suitable for children to drink.

It is better for normal people to drink boiled water and mineral water every day. Mineral water contains minerals needed by human body, which can supplement human body's needs and is more suitable for normal people to drink than pure water. Boiling water easily penetrates the cell membrane and enters cells, which promotes human metabolism, enhances human immune function and improves human disease resistance. It is the most suitable drinking water for human body.

Why is well water cool in summer and warm in winter?

There is little difference in well water temperature between winter and summer, which is basically around 15℃, so it feels warm in winter and cool in summer due to the change of environmental temperature all the year round. Similarly, when you take things out of the refrigerator, your hands feel nothing in winter, but you feel very cold in summer. At this time, although the temperature in the refrigerator is almost the same in winter and summer, it feels different because of the different ambient temperatures.

Compared with the ground temperature at that time, people felt that the well water was warm in winter and cool in summer. In hot summer, the earth's surface is directly affected by the sun's irradiation and airflow, and the temperature rises rapidly. Underground soil can only absorb heat from the atmosphere through the upper soil. Because of the slow heat transfer in soil, the temperature in the deep underground is lower than that in the ground, so the temperature in well water is lower than that in the ground.

If the well water is lifted to the ground, it will feel particularly cold. In cold winter, the ground temperature drops rapidly, often below 0℃, and the water on the lake will freeze. Because the soil deep underground can't directly dissipate heat into the air, the underground temperature changes little, and the temperature of well water is higher than the ground. At this time, the water is lifted to the ground and it feels hot.
