What is the connection between water and human health?

Life comes from water, without which human beings can't live. The functions of water in human body include: maintaining cell morphology, increasing metabolic function, regulating the normal circulation of blood and tissue fluid, dissolving nutrients to make them easy to absorb and transport, helping to excrete wastes in the body, releasing heat, regulating body temperature and maintaining blood acid-base balance. In a word, water is the key to human function. Without water, there is no life. Generally speaking, the human body needs 2 ~ 3 liters of water every day, that is, 10 glass of water, of which 4 cups are from food and 6 cups are from drinks. If the intake of water is insufficient, the human body can reduce the discharge of water through regulation mechanism, but when it is seriously insufficient, it will reduce the water in the body. When the water content drops to 2% ~ 10% of the body weight, it can cause substance metabolism disorder in the body due to dehydration; When the water content drops to 7% ~ 14% of body weight, severe dehydration symptoms and signs appear; When the water content drops more than 14%, it is life-threatening. Many people only drink water when they are dry, which is a misunderstanding. Dry mouth is only the last signal sent by the body when it is approaching the dehydration stage, so we should attach great importance to drinking water and be sure to drink enough water consciously, which will make you healthier, more energetic and live longer.

However, polluted water is the source of all diseases. In China, about 80% people drink polluted water, and more than 2,000 kinds of harmful substances have been found in tap water, of which carcinogens account for 2.7%. According to relevant medical statistics, more than 50 million children die of water pollution every year in the world. 70 million people suffer from lithiasis; 90 million people suffer from hepatitis; 30 million people died of liver cancer and gastric cancer. 80% ~ 90% of human diseases come from drinking polluted water. Drinking water requires drinking fresh water. The so-called fresh water refers to tap water, clean well water and clean river water, including boiled water that has not been stored for a long time. This kind of water is not polluted by nitrogen oxide bacteria in the air and can be quickly absorbed by human cells. On the contrary, if it is old water exposed to the air and stored for more than 3 days, the harmful substances in the water, especially nitrite, will increase greatly, and nitrite can be converted into carcinogenic nitrosamines after being absorbed by the human body. In short, drink fresh water when drinking water.

The traditional water treatment methods in waterworks can no longer guarantee the provision of high-quality drinking water, so various brands of water purifiers came into being.

Now many families are drinking various brands of bottled water, but they don't know that water is alive. No matter how good the water is, don't store it for more than 3 days. After a long time, water will age, lose its activity and become "stagnant water". Drinking aging water regularly will accelerate aging and affect health. The best way is to install a domestic water dispenser and connect it directly to the tap water. This is called terminal equipment, which eliminates the secondary pollution of water. There are many kinds of this kind of equipment in the market, both at home and abroad, with different prices. To choose the best quality equipment carefully, it must pass the inspection of Chinese Academy of Preventive Medicine. Families with good economy can choose to pass the national sanitation foundation (NSF) inspection, because NSF is the highest authority in the world, and its recognized products are exempt from inspection in any country and region in the world. Buy a water dispenser, don't just be cheap.
