Protein , vitamins... are nutrients that people often talk about. But what is little known is that water ranks first among the six essential nutrients in the human body. Therefore, drinking water healthy is the most important thing for everyone every day, even in their life.
Scientific research has found that the human body with normal vital signs has about 70%, the water content in the blood is about 80%, and the water content of newborn fetus in the mother's body is even as high as 97%.
In other words, 2/3 of our body is water, and the breathing of the skin, the circulation of blood, the vitality of cells... all human life activities are inseparable from water. As early as the "Compendium of Materia Medica", it was recorded that "medicine is not as good as food supplement, and food supplement is not as good as water supplement." Yes, the importance of water to the human body.
The importance of water is self-evident, and the water people drink every day is more important. As for how to drink water, how much water to drink, and what water to drink, they are all topics of concern.
01
Is overnight water harmful to the body?
Overnight water is not something that cannot be drunk. Whether the water can be drunk depends on the length of storage time, whether the storage container is clean, whether the ambient temperature is appropriate, and the number of bacteria in the environment, and it has nothing to do with whether it is overnight.
Water is affected by environmental conditions and has a long and short storage time. It is not something you can't drink after overnight. Generally speaking, even overnight water can be drunk when the ambient temperature is appropriate, the number of bacteria in the environment is low, the container containing water is clean, the storage time is not long, and the seal is tight.
When the water is directly open and uncovered for a long time, it is susceptible to bacterial contamination. Drinking it may cause diarrhea. It is not advisable to drink it again at this time, but it has little to do with whether it is overnight.
02
thousand boiling water is harmful to the body?
The so-called thousand-boiling water is water boiling on the stove for a night or a long time, and water boiling repeatedly in an electric water heater. Many people think that such thousand-boiling water cannot be drunk, otherwise it will cause harm to the body and may even cause nitrite poisoning or cancer.
Occasionally drinking thousands of boiling water will not affect the body, but drinking it for a long time may affect the health. If it is long-term and large-scale exposure, it may increase the risk of certain malignant tumors.
Experimental investigation shows that as the tap water boils more times, the content of nitrite in the water does not decrease but increases. If you drink it in large quantities for a long time, it is indeed not conducive to your health. For the sake of health, it is recommended to boil water and put it in a thermos pot for drinking.
03
What you really can't drink is this kind of water. Many people don't know
[Tap water just boiled]
Many people like to drink boiled water, but do you know? The water cannot be drunk as soon as it boils. Because our tap water has been chlorinated and disinfected, the combination of chlorine with the residual organic matter in the water will produce halogenated hydrocarbons , chloroform and other carcinogenic compounds.
[Bottled Water]
Easy to carry and can be drunk with open lid. Bottled Water is favored by more and more consumers. However, the polyester bottles used for bottled water often contain substances that may cause chronic poisoning in the human body, especially when the bottle is in a high temperature environment or is not drunk in time after opening, harmful substances will seep into the water, which is harmful to health. Therefore, bottled water must not be heated or exposed to the sun.
[Raw Water]
Raw Water refers to clean water that has not been disinfected and filtered and boiled. The newly released tap water or well water is called raw water.
Raw water contains bacteria, viruses and parasites that are harmful to the human body. Drinking raw water can easily cause acute gastroenteritis, viral hepatitis, typhoid fever, dysentery and parasitic infections.Especially today, rivers, reservoirs, and well water are contaminated by factory waste liquid, domestic waste water and pesticides to varying degrees, and drinking raw water is more likely to cause diseases.
