People cannot live without water。Adult body water accounts for about 60%, if the water is reduced to 20% of the original body weight, people can not survive。To stay alive, a person needs about 2 liters of water a day from food。March 22 is World Water Day and a special day to remind the public of the importance of water resources。Learning the science of drinking water can help us live longer and healthier。
The following points are often bad drinking habits in our daily life:
1. Insufficient daily drinking water。Some people think that there is no need to drink water if you are not thirsty, in fact, the human body cells continue to metabolize, eliminate waste, and emit heat will lose water, so it is necessary to maintain the balance between human daily water intake and discharge。When drinking insufficient water, the severe degree of water shortage in the body will cause increased osmotic pressure of blood circulation, if the water is not timely replenishment, the water in the intracellular fluid flows to the interstitial fluid to produce intracellular dehydration。If you wait until you are thirsty to drink water, it indicates that the water loss in the body has been serious, so we should develop the habit of drinking water actively at any time。
Second, beverage water is equivalent to drinking water。Many people do not like to drink water, but prefer to drink with gas, sweet, sour drinks。In fact, drinks can not replace drinking water，Drinks not only easily cause anorexia and aversion to water，In the long run, it can lead to nutritional deficiencies，Drinking too much acidic drinks will make the body's blood acidic,Bad for blood circulation，And lactic acid accumulation in the muscle，Prone to fatigue，This leads to a decline in the body's immunity，And prone to cold, dental caries, periodontitis and other diseases。
Third, drink tap water。Some people mistakenly think that drinking raw tap water is nutritious, especially in the summer like to figure convenient, on the tap water tap to drink, it is easy to be infected with diarrhea, typhoid, cholera and other intestinal diseases。
4. Drink pure water regularly。Mineral water and purified water are obtained by natural mineral water processing and sterilization, almost does not contain any impurities, and is rich in various trace elements。However, as daily drinking water, their price is high and it is difficult to adapt to people's life needs。In addition, long-term drinking of pure water that does not contain any nutrients may lead to diseases due to the lack of various elements, the light will not eat well, can not sleep, fatigue, and the heavy will be nervous disorders, osteoporosis, anemia and so on。
Five, drink thousands of boiling water for a long time。We advocate drinking boiled water, but oppose drinking thousands of boiled water for a long time。The water that has been boiling for a long time on the stove, and the water that has been repeatedly boiled in the electric water heater is called thousand boiling water。Its water calcium, magnesium and other heavy metal components and nitrite content is very high, long-term drinking of this water will interfere with human gastrointestinal function, resulting in diarrhea, abdominal distension, and toxic nitrite will also cause body hypoxia, and cause neurological, urinary and hematopoietic system lesions。
