Purified water takes city tap water as its water source, and removes harmful substances and all nutrients in the water. Therefore, pure water can not replenish the electrolyte lost in the human body in time, but also dilute the concentrated electrolyte in the body.
A state in which the human body loses the dynamic balance of electrolytes. After such water enters the human body, it will interfere with the transmission and distribution of water between cells in the body and affect the functions of important organs.
The state of water in human body is not "pure water"
People need water for various physiological activities. For example, water can dissolve various nutrients and help the human body absorb them. Water flows endlessly between blood vessels and cells, transporting oxygen and nutrients to tissues and cells, and then discharging metabolic wastes from the body. In short, people's various metabolic and physiological activities are inseparable from water.
All substances transported or biotransformed in human organs are soluble in water. When the human body ingests nutrients from the outside, water always mixes different electrolytes (such as potassium ions and sodium ions) in human organs. In order to maintain the normal activity of the body, the electrolyte in the human body is in a state of dynamic balance.
Therefore, the state of water in the human body is not "pure water", but a salt mixture suitable for transporting electrolytes.
People's Daily Online-German Nutrition Association: Drinking purified water for a long time is not good for human health.
