Is it harmful to drink cold water and hot water, and is it harmful to drink boiled water mixed with

There are two types of hot and cold water mixed with drinking:

1. If it is mixed with cold boiled water (boiled water), because after the process of high temperature sterilization, most of the pathogenic bacteria are killed, so the impact on the human body is small; If it is mixed with raw water, such as tap water, it may bring in some microorganisms or pathogenic bacteria, and the water temperature cannot achieve the sterilization effect, which may cause diarrhea and other intestinal discomfort symptoms.

2. Yin and yang water is half cold water and half boiling water, which can be used as a medicine primer for magic or traditional Chinese medicine. In the ancient recipe, it was necessary to take rainwater from the sky that had not touched the ground, and underground water from wells that had never seen the light of day, and the modern simplified version was tap water.

3. Mix the cold water in the water dispenser with hot water, the cleanliness of the water dispenser and the quality of the bottled water are very important. If the cleaning is not in place, and the internal filter element of the water dispenser is not replaced as required, the water will also bring out a lot of bacteria through the filter element. If the quality of the bottled water is not up to par, or if the tap water is filtered directly from the water dispenser, then drinking hot and cold water alternately may be harmful to the body.

1. If the cold water is cold boiled water, it is okay. This mixture of hot and cold water is commonly known as "yin and yang water". The main nutrient is water, and from the perspective of nutrients alone, it can be mixed and drunk.

2. If it is cold tap water with boiled water, no. The stomach will not be able to stand it. Because tap water is added to boiled water, it is heated and the temperature does not reach 100, which may produce some undesirable substances.

3. Bottled water is treated and clean. This kind of yin and yang water, which is made up of cold water and boiled water, has no literature to support that drinking this water is harmful to the body. In terms of nutrients, cold water and hot water contain basically the same nutrients, but some heavy metal elements will be lower, such as:

Calcium, magnesium.

No, warm water is best, cold water is not recommended from the refrigerator.

If it's plain water, of course it doesn't matter. If it is raw water, it is definitely not recommended and unhygienic.

I don't think it's a big problem, just mix the water at the right temperature.

Cold water should be boiled and cooled, or straight water. It is no problem to mix hot and cold water.

If it's all water from the water dispenser, there's no harm.

Since the tap water is not boiled, there is a problem with bacteria in the water. Harmful.

The mixture of hot and cold water is also called yin and yang water, as long as it is boiled, it will not be harmful and can be drunk.

It is best not to mix cold water and hot water, which is harmful to the body, and it is best to drink it cold and white.

There is no harm in drinking boiling water mixed with cold water. It is a very common phenomenon to drink hot and cold water from a water dispenser. Whether the alternating hot and cold water on the water dispenser is harmful to the body, the most important thing is the quality of the bottled water.

If the quality of the bottled water is guaranteed, then there is no big problem with the hot and cold water on the water dispenser. If the quality of the bottled water is not up to par, or the tap water is filtered directly from the water dispenser, then drinking hot and cold water alternately may poison the body. In this case, cold water is "raw water" that contains a lot of bacteria.

The key is the quality of the water. If the quality of the water is guaranteed, then there is no big problem in drinking the water hot and cold. If the quality of the water is not up to par, or if you drink tap water filtered directly from a filter bucket, then drinking hot and cold water alternately may poison the body.

In this case, cold water is "raw water" that contains a lot of bacteria.

Calcium and magnesium ions are essential nutrients for the human body every day, and if the water has a certain hardness, a certain amount of calcium and magnesium ions can be replenished by drinking water. If you are taking soft water for a long time, you need to supplement it through other ways. But it's not good to have too much or too little hardness of water, because the hardness of water is closely related to some diseases.

In areas with high water hardness, the incidence of cardiovascular diseases was lower, but the incidence of kidney stones increased with the increase of water hardness. The south of our country is mostly soft water, and the northern part of the country is mostly hard water. The standard of drinking water in China is not more than 25 degrees, and the hardness of the most suitable drinking water is 8-18 degrees, which belongs to mild or moderate hard water.
