Ans:
1. Why is water the source of life?
A: 75% of the human body is water, 75% of the Earth's surface is water, which the universe by chance coincidence? The people to eat for days, food to drink first. Diet diet, first "drink" after "food". Water is a macronutrient, there is no other nutrient that can participate in human function as extensively as water. Every organ of the human body is extremely rich in water, blood and water in the kidneys accounted for 83%, 80% of the heart, 76% of the muscle, 75% of the brain, 68% of the liver, that is, the bones also contain 22% of the water.
Life consists of cells, which must be "soaked in water" to survive. Dryness is the main manifestation of aging. Young people accounted for 42% of intracellular water, the elderly accounted for only 33%, so the wrinkles, subcutaneous tissue gradually shrinking. The process of aging is the process of losing water. People can not eat for a few days, but not a day without drinking water, the human body if the loss of 15-20% of body weight in the amount of water, physiological functions will stop, and then die.
2. What is the specific gravity of the body's water content?
A: As we all know, the human body is close to 70% water. That is, weighing sixty kilograms of people, water accounted for forty kilograms of strong. In the case of infants, more than 80%, still in the mother's body of the fetus water proportion is even higher. The elderly body water content is only 50-60%.
3, the special properties of water?
A: Water has many special properties that have attracted attention in recent years. For example: water in the ice when the volume instead of increasing; capillary water or water in the organism, they are also known as interstitial water, can be -110 ℃ also does not freeze; water molecular formula is H2O, molecular weight of only 18, it is at room temperature in the liquid state.
4. Is the water you drink safe?
A: 1) Tap water is the water plant to the water in the river, river and lake after treatment. At present, China generally use water treatment plants, centralized water supply, and then by the water pipeline to the residents of the family in the supply of drinking water. For high-rise buildings, the use of high-rise water tanks secondary pressurized water supply. However, industrial development caused by the pollution of water sources is becoming increasingly serious, by the process, technology, economic and other conditions, the water plant on some of the pollution but can not help.
Currently in the tap water disinfection process using a certain amount of chlorine (bleach), resulting in chlorine residue in the water, and organic matter in the water to generate trichloromethane. It is now known that trichloromethane is the main carcinogen in tap water, in the cold water state, trichloromethane more in the specified range, but the tap water in the heating of the content of trichloromethane rose sharply, especially in the 95 ° C to 100 ° C when the content is the highest, boil more than five minutes to reduce the residue. In addition to chemical pollution, pipeline corrosion, insoluble calcium in the water, organic matter and high-rise buildings, such as water storage tanks, secondary pollution of tap water is also more serious.
2) boiling water is dead water
Chinese people are accustomed to drinking boiled water, that is, boiling water obtained after boiling. Said tap water is not safe, which, after all, there is a certain amount of dissolved oxygen and minerals, and the process of heating the water, dissolved oxygen in the water will be due to warming and dissipation, the more terrible is that the boiling water in the content of trichloromethane is the tap water 3 - 4 times. No wonder the cooling of the boiling water to water flowers withered, fish fish death.
3) Pure water (space water, distilled water) ≠ good water
Drinking pure and hygienic water, is our current drinking water standards, and scientists have reminded people that "pure water is not equal to healthy water". Scientists define the new standard of drinking water is: on the basis of pure oxygen-rich, with activation function, solvency and permeability.
Pure water does not contain impurities and harmful substances, but its nutrition and secondary pollution, has been a lot of different opinions, mixed reviews.
4) Mineral water is said to contain minerals, trace elements, but some medical experts have suggested that the degree of mineralization to how much beneficial to the human body has not yet been scientifically quantitative research, and mineral water is not beneficial to anyone, and there are a lot of fake products on the market is difficult to distinguish.
5, the elderly and children long-term drinking pure water is beneficial?
Answer: China Consumers Association issued a consumer alert that experts pointed out that most of the human body is suitable for drinking weak alkaline water, the elderly, children and young people, infants and young children in particular, should not be pure water as the usual drinking water a large number of long-term drinking.
The results of the sampling of barrels of purified water in mainland China in the past two years show that the overall quality of the industry is poor, and the quality of the product is seriously polarized. It is understood that a large number of mainland China's pure water used in reverse osmosis technology processing made. This method uses reverse osmosis membrane device to achieve the purpose of water purification. This method not only can effectively get rid of bacteria and organic matter and other pollutants, but also effectively remove calcium, magnesium, manganese, zinc, silicon and other organic matter. Therefore, pure water is basically pollution-free, also basically no nutrients.
6, how many human diseases related to drinking water?
A: The World Health Organization survey pointed out that 80% of human diseases are related to water. The main method of disinfection of tap water is chlorination sterilization, although it can remove a large number of bacteria, but there are harmful substances, especially heavy metals in the water, chlorine molecules and nitrites and other components. At the same time the delivery process, water tower storage, etc. have caused a certain degree of secondary pollution. Although the water will be boiled, but can not remove heavy metals and other harmful substances in the water, the excessive intake of these substances, can cause great harm to the human body.
7, what are the main diseases caused by water pollution to humans?
A: Cancer: nitrite compounds, trichloromethane, radiation particles
Liver disease: industrial wastewater and pesticides contained in the toxic organics, heavy metals, etc.
Stones: high hardness of groundwater
Cardiovascular: high levels of inorganic salts
Dementia: aluminum metal, etc.
Skeletal disorders: cadmium, heavy metals
Hematopoietic diseases: heavy metals
Endocrine disorders: toxic organic substances, high content of inorganic salts, heavy metals, etc.
8. What are the characteristics of diseases caused by water pollution?
Answer: (1) progressive: the slow accumulation of various toxic substances in the body until the onset of the disease, because of the longer time is not easy to notice, more insidious.
(2) Not easy to decompose: most of the toxic organic substances and all the heavy metals in the human body can not be decomposed and metabolized, can only be in the body for a long time to stay, and continue to accumulate.
(3) Easy to accumulate in the body: Once the heavy metals enter the body, they will be combined with human proteins to form compounds that are difficult to metabolize.
9, longevity village longevity secrets?
A: Longevity village in the Caucasus region of the southern Soviet Union is very famous. Caucasian longevity village is the only place in the world where there is no cancer, and even the incidence of adult general disease is extremely low. In this region, more than 100 years old people abound, the average life expectancy of 120 years old, they do not have the pain of disease, dying a sleep, very peaceful to leave this world.
Further research by scientists found that the water consumed by people in the longevity village is weak alkaline water with small molecular groups. So they came to the conclusion that "people in the village of longevity often drink alkaline water, and excrete clean feces in their daily lives, which makes it easy for them to achieve health and longevity".
10, the standard of quality drinking water?
A: The World Health Organization (WTO) based on the analysis of the results of a large number of surveys of the world's longevity areas, put forward six standards of quality drinking water is:
1) does not contain harmful to human health of the physical, chemical and biological contamination;
2) contains an appropriate amount of beneficial to human health, and ionic state of minerals (potassium, magnesium, calcium, etc., content of 100mg / L);
2) contains a moderate amount of beneficial to human health, and ionic state minerals (potassium, magnesium, calcium, etc., the content of the water in the 100mg/L);
3) The molecular group of water is small, with strong solubility and penetration;
4) It should be weakly alkaline (PH value of 8-9);
5) The water contains dissolved oxygen (about 5mg/L), and carbonate ions;
6) It can quickly and effectively remove the acidity of body metabolites and various harmful substances.
So far, only active ionized water can fully meet the above standards. Therefore, it is not only suitable for healthy people to drink for a long time, but also due to its obvious regulation of gastrointestinal function, regulation of blood lipids, antioxidant, anti-fatigue and cosmetic effects, it is also very suitable for gastrointestinal diseases, diabetes, high blood pressure, coronary heart disease, renal disease, obesity, constipation, and allergic diseases, such as patients with adjuvant therapy.
11, which people are prone to water shortage?
A: The old man's sensitivity to thirst is reduced, so the body is often in a state of water loss, less secretion of digestive juices, easy constipation, blood viscosity, cardiovascular health is not good.
Babies have a strong metabolism and fast growth, so the amount of water needed to replenish per unit of body weight is higher than that of adults, although babies are mainly liquid food, but it is also advisable to feed some water in the middle of the two breastfeeding.
Children's movement is large, the need for water is correspondingly more, but the children often play and forget to drink, to the near meal time to rush to drink water, so that affects the digestion and absorption of food.
12, thirsty how to drink water?
A: "Thirsty not drink" is a proverb. If you drink too much water at one time, more than the stomach's capacity, the stomach will swell too much to cause an uncomfortable feeling in the stomach. In addition, the stomach suddenly into a large number of water, all of a sudden the gastric juice diluted, will inevitably affect the digestion of gastric juice and sterilization function. More importantly, a large amount of water is absorbed by the blood, so that the blood volume suddenly increased, the concentration decreased, the burden on the heart increased, when the heart is not functioning well, there will be panic, shortness of breath, chest tightness and other feelings of discomfort. When the heart is not functioning well, there will be panic, shortness of breath, chest tightness and other uncomfortable feelings. When thirsty, first drink a few mouthfuls of water, moisturize the throat, stop for a while and then drink, you can also drink some light saline water to replenish the loss of salt. The use of "many times, a small amount of" drinking method, is good for health.
13, not thirsty to drink water?
A: If you wait until you are thirsty to drink water, then the body is already dehydrated. The active principle that people should take the initiative to drink water regularly. In addition to three meals, the average adult needs another 1500-1800 milliliters of water per day. When it is hot and sweaty, the water intake should be increased. "Not thirsty also drink water" is more important for middle-aged and elderly people, if middle-aged and elderly people can adhere to the initiative to drink the right amount of water every day, to improve blood circulation, prevention and treatment of cardiovascular disease are favorable.
14, the elderly should drink more water?
A: summer to drink more water, the elderly in particular to do active drinking. The water in the body of the elderly is about 1/3 less than young people, coupled with the heat of the day more sweat, the body is more dehydrated. Not thirsty is not the same as no water shortage, even if the elderly do not feel thirsty, but also to drink more than 1,000 milliliters of water every day, drink more water, small amounts of time, usually not thirsty to drink, but also can be appropriate to drink some light tea water. And the amount of urine per day should not be less than 1000 ml, so as to ensure that the blood can be diluted, to maintain the body sufficient blood volume, reduce blood viscosity, excretion of toxins, reduce the burden on the heart and kidneys. Especially in the sweat or fever, diarrhea, it is more important to drink more water, in order to facilitate blood dilution, promote blood circulation in the brain, to prevent embolism.
15, the best time to drink water for the elderly?
A: After getting up in the morning: must drink water, because it is the key to the day the body began to move. Elderly people sleep at night, due to urination, sweating, breathing, the body's blood concentration, slow blood flow, function metabolite accumulation. Drinking a glass of water after getting up can make the blood circulate normally, and has the effect of preventing the occurrence of hypertension, cerebral thrombosis, myocardial infarction and other disorders. Running after drinking water is more beneficial. Drinking water in the morning is best on an empty stomach, drink 450 milliliters of water at a slow rate in small mouths, and do simple actions after drinking not ***.
Around 10 am: This is the time of the day when the body's biological clock is at its peak, and should be supplemented with 300 milliliters of water. Around 3 p.m.: this happens to be the time to drink afternoon tea, drink 400 milliliters. Before going to bed: drink 400 ml before going to bed, for the elderly or people suffering from cardiovascular disease, drinking water before going to bed in the evening can prevent lethal infarction. Many older people are not used to drinking water before bedtime for fear of getting up in the night. In fact, the elderly bladder atrophy, capacity reduction, do not drink water as usual to get up at night. In the middle of the night: drink 200 milliliters, the elderly due to renal contraction function decline, more urine at night, which leads to a lack of water in the body, easy to make the blood viscous, cardiovascular and cerebral blood resistance, easy to cause cardiovascular and cerebrovascular lesions. The first thing that you need to do is to get your hands on some of the most popular products in the world.
Drinking water at special moments:
After exercise: Although we are not athletes, the amount of exercise is not so big, but no matter what exercise, such as cleaning the room after should drink water, so it is not easy to get tired, and it is not easy to generalized soreness.
In an air-conditioned environment: especially need to hydrate.
