Pure water Pure water refers to pure, clean and impurity-free H? O, and does not contain any additives, colorless and transparent, can be directly drunk, referred to as pure water or pure water.
Most of the bottled water and bottled water we drink in our daily life belong to the low mineral water on the market, and pure water also belongs to the ranks of low mineral water. The concept of pure water is simply the water quality that can be directly drunk after most soluble inorganic salts and ions in water are removed by filtration and reverse osmosis of separation membranes.
Tap water tap water refers to the water produced after purification and disinfection by tap water treatment plant, which meets the national drinking water standard and is used for people's life and production. It is mainly treated by filtration, sedimentation, disinfection and other processes in the waterworks. Finally, it is treated by the waterworks according to the national sanitary standard for drinking water, and then it is supplied to all households through water transmission and distribution pipelines with pumps.
Is there any harm in drinking tap water for a long time? In fact, there is no research that drinking tap water that meets the national health standards is harmful to people's health, but the standards of tap water in different regions are different, so drinking tap water raw will affect people's health more or less.
1. Effective chlorine for disinfection
Different water plants in different regions have different water quality after treatment. The available chlorine in tap water reaches the national minimum standard of 0.05mg/L, but the concentration of available chlorine is high in some areas, and long-term drinking will cause certain harm to the body.
2. Physical stimulation of tap water
Tap water cannot be drunk directly. Drinking tap water directly has a great influence on the digestive tract and may cause digestive tract diseases.
It should be noted that when drinking tap water in daily life, you should not drink it directly, but heat it before drinking it, because some microorganisms and bacteria in the water can be killed in the process of heating tap water. It is no problem to drink boiled and heated tap water directly. Although there will be some scale, it meets the drinking requirements and will not cause any harm to the human body.
Is drinking pure water harmful to human body for a long time? Most people think that pure water not only removes substances harmful to human body, but also removes many substances that are very important to human health? Essential trace elements for human body? So they think drinking pure water for a long time is definitely harmful to human body. What's the truth?
The first thing we need to understand is why we need to replenish water and the role of water in the human body. In fact, the most important function of water is as a carrier. The so-called carrier is mainly embodied in two aspects. One is to transport nutrients in the body to promote the digestion, absorption and metabolism of nutrients, and the other is to transport the waste metabolized in the body to the outside. In this way, water plays a role in human metabolism, and in this respect, the role played by water far exceeds that provided by water as a nutrient.
Secondly, although pure water is prepared by reverse osmosis, ion exchange, distillation and other processes, it is true that there are almost no minerals in pure water through these processes, but the minerals and trace elements provided by water only account for 1% of the total minerals and trace elements needed by human body. In fact, all kinds of nutrients, minerals and trace elements needed by the human body are mainly taken from meat, vegetables and fruits, such as calcium supplementation. Drink more milk and eat more kelp when supplementing iodine. We drink water mainly to meet the body's demand for water, so drinking pure water for a long time has no effect on human health at all.
Tips: After getting up in the morning, before going to bed, after exercise and half an hour after meals, you should properly replenish water.
