One-sided emphasis on minerals in water
Mineral water is deeply loved by everyone because it contains some minerals needed by human body. But many people think that the higher the mineral content, the better, but it is not. Drinking water should contain appropriate and balanced minerals, but the high mineral content does not fully explain the strong vitality of water. On the contrary, when the mineral content in water exceeds the standard, it will also endanger human health. For example, when the content of iodide in drinking water is 0.02-0.05 mg/L, it is beneficial to human body, and when it is greater than 0.05 mg/L, it will cause iodine poisoning.
The purer the water, the better.
Many people think that the purer the water, the better. In fact, drinking pure water for a long time can also lead to malnutrition. Drinking a lot of pure water will take away useful trace elements in human body, thus reducing human immunity and easily causing diseases. Because human body fluids are slightly alkaline and pure water is slightly acidic, if you drink slightly acidic water for a long time, the environment in your body will be destroyed. Experts pointed out that drinking pure water for a long time will also increase the loss of calcium. For the elderly, especially those suffering from cardiovascular diseases and diabetes, children and pregnant women should not drink it for a long time.
Drinking water is just to quench your thirst.
Drink water only when you are thirsty, and don't replenish water if you are not thirsty. People often ignore the nutrition and health care function of water when drinking water. Clean, safe and healthy water is the cheapest and most effective health care product. Water can dilute protein, fat, carbohydrates, minerals, inorganic salts and other nutrients in the body, making it easily absorbed by the human body. Because the metabolism of all cells is inseparable from water, only by letting cells drink enough water can they promote metabolism and improve their resistance and immunity.
Beverage = drinking water
Many young people like to drink as drinking water. In this regard, experts remind that water and drinks are not the same in function. Because the drink contains sugar and protein, and a lot of flavors and pigments are added, it is not easy to make people feel hungry after drinking. Therefore, using drinks instead of drinking water can not only replenish water to the body, but also reduce appetite and affect digestion and absorption. Drinking caffeinated carbonated drinks for a long time will lead to excess calories, increased blood lipids and increased cardiovascular burden. Caffeine, as a diuretic, can lead to excessive urination and dehydration. In addition, for children, carbonated drinks will destroy the enamel on the outer layer of teeth and easily lead to dental caries.

Medical water can be used as drinking water.
At present, some drinking water named "electrolytic water" and "oxygen-enriched water" can be seen in the market. Strictly speaking, these are all medical water, which cannot be used as drinking water for normal people. Electrolytic water is to decompose water into cationic water and anionic water by electrolysis. Cationic water is medical water and must be drunk under the guidance of a doctor. Negative ion water is often used in disinfection and other aspects. Oxygen-rich water refers to artificially adding more oxygen to pure water. Oxygen molecules in this water enter the body, which will destroy the normal division of cells and accelerate aging. However, after oxygen is added to purified water, it is still macromolecular water because of its molecular structure, and it is not easy to be absorbed by cells.
2. What is the importance of scientific drinking water?
Ten elements of scientific drinking water 1.
Drinking water regularly turns passive into active. The only reason why many people drink water is that they feel thirsty. Thirst is a physiological response of human body, however, this physiological response is not synchronized with the water balance of the body-the physiological response of "thirst" is relatively lagging behind.
In other words, when we feel thirsty, the body's water has long been out of balance, and some cells have been dehydrated. At this time, drinking water is already "passive drinking water". Over time, the human body will be in a potential water confirmation state for a long time, which is not conducive to the normal metabolism of the human body.
Drinking water regularly means taking the initiative to drink water, that is, drinking water on time without waiting to feel thirsty, so that the body does not feel thirsty. This is not only beneficial to the metabolism of the body, but also receives the effect of "internal washing", thus improving endocrine and organ functions and enhancing immunity.
So drink water regularly, change passive drinking water into active drinking water, and don't make yourself feel thirsty. Element 2: quantitative drinking water As mentioned above, adults generally drink 1200- 1500 ml of water every day except the water in food.
The daily drinking water of the elderly can be controlled at around 1500ml. In the case of excessive sweating in summer, the amount of drinking water should be increased accordingly. Normal people sweat about 1000ml in summer. If strenuous physical activity is carried out at high temperature, the amount of sweating can be as high as 8000 ml.
At this time, it is more important to replenish water in time. In addition, in order to supplement the inorganic salts discharged with sweat, it is necessary to supplement water, fruits and soups in an appropriate amount to maintain the water-electrolyte balance.
Element 3: Cultivate scientific drinking methods First of all, don't drink a lot of water (more than 500ml at a time) when you are thirsty. A large amount of water enters the body at one time, which not only affects the digestive function, but also causes radiation hyperhidrosis and increases the burden on the heart and kidneys.
Secondly, don't just drink two mouthfuls of water to "quench your thirst" when you are thirsty, otherwise the water you drink will be difficult to be effectively absorbed and utilized by your body, which will not help to alleviate the water shortage of your body. Scientific drinking method: slowly drink a whole glass of water (200ml) at a time.
Old people can divide a glass of water into two times (each time 100 ml) and drink it slowly, which can make the body use effectively. In addition, when drinking water with a slightly higher or lower temperature, you can put the water in your mouth first, slowly swallow it after a slight delay, so that your mouth and internal organs can adapt to the water temperature, and then drink it incrementally.
The fourth element of establishing a drinking schedule: "Getting up in the morning and going to bed late, not drinking for a long time, coupled with the explicit and implicit perspiration and urine formation of the body, is equal to physiological water loss, which makes the body relatively short of water, leading to an increase in blood concentration and a slowdown in blood flow, resulting in the accumulation of metabolites in the body. Drinking water in the morning can be quickly absorbed and utilized by the evacuated gastrointestinal tract, which is helpful to reduce blood viscosity, purify blood, increase blood vessel elasticity, promote blood vessel expansion and accelerate blood circulation, especially for the prevention and treatment of diseases such as hypertension and cerebral embolism.
In addition, drinking water in the morning can also prevent constipation caused by fecal deposition. Suggestion: Drink 250 ml of warm water every morning.
Element 5: Drink water one hour before meals. At this time, add an appropriate amount of water (100- 150ml). After water stays in the stomach for a certain period of time, it will be supplemented to the tissues of the whole body with blood, and there will be enough digestive juice in the body for digestion when eating. Element 6: Control the temperature of drinking water. The water temperature is too high or too low to drink. Too hot water can easily burn the mouth, esophagus and gastric mucosa.
Excessive drinking water and food are considered to be the physical factors of upper digestive tract cancer. Ice water may cause gastrointestinal spasm.
Generally, when water is boiled for 3-5 minutes and naturally cooled to 20℃-25℃, it is suitable for drinking. At this time, the gas in the water is reduced, the cohesion is increased, the molecules are close, the surface tension is strengthened, and it is close to the biological cell water, so the affinity with human cells is strengthened.
This temperature is the best for drinking. Factor 7 Drinking raw water without effective measures may contain chlorine, bacteria and organic residues in eggs. It may pose a potential threat to human health and may lead to acute gastroenteritis and some infectious diseases.
Therefore, not drinking raw water should be everyone's drinking criterion. Element 8 is exposed to boiled water without drinking old water for more than 4 hours, and gas is easily mixed into it, which makes the biological activity of water lose more than 70%, and bacterial impurities mixed into the water pollute the water.
In addition, water stored at room temperature for 3 days will produce 0 per liter of water. 9 14 mg nitrite, a carcinogen, can also make the blood lose its oxygen transmission ability, especially the water in the thermos. The scale is a mixture of heavy metals and salts, mainly calcium carbonate, which contains elements such as cadmium, lead and arsenic, and is harmful to human body.
Element 9: Don't drink water repeatedly boiled for a long time, water repeatedly boiled by electric water heaters, etc. , which is the so-called "thousand boiling water". Because the water has been boiled for too long, the content of heavy metals such as calcium and magnesium in the water has increased. Drinking this water for a long time will interfere with people's gastrointestinal function, leading to diarrhea and bloating.
Thousands of boiled water will also reduce nitrate in the water to nitrite, the precursor of carcinogens, which is harmful to health for a long time. Element 10: Establish drinking water schedule. Everyone should establish their own drinking schedule according to their daily life, life and work characteristics, and stick to it.
The following is the reference pattern. 6-7 am; Drink 250 ml of water (after brushing your teeth), have breakfast 30 minutes after drinking, and drink 200 ml of water at 9 am (30-60 minutes after going to work).
1 1 point in the morning (before lunch 1 hour), drink 150ml, and drink 200ml at 3pm. Drink 1 50ml water at 5pm (before work1hour).
Drink 250 ml of water in the afternoon 10 (before going to bed). .
3. Common sense of life: How to drink water scientifically
Now, more and more people pay attention to drinking water; But only a few people can really drink.
Drinking at the wrong time, without considering the content and thinking, can only prove that you just drink water, but you don't necessarily drink the right water. In this era when caring for the body has become popular, drinking water, once considered the simplest, will also become a profound knowledge.
1, Hydrate water seriously in the morning Many women regard drinking water after getting up as their daily homework, in order to relieve constipation, reduce blood viscosity and make the whole person look watery. But how to replenish water in the morning is healthier? In fact, there is no certain rule, and breakfast hydration varies from person to person.
People with thin skin and cold constitution are not suitable for drinking milk, juice or cold water below body temperature in the morning, and can change to warm soup and porridge. Freshly squeezed juice is not suitable for drinking on an empty stomach in the morning, even in summer.
It is forbidden to replenish water and avoid salt in the morning. Thick broth and salty wonton soup are not suitable for drinking in the morning, which will only aggravate the thirst of the body in the morning.
2. Do you need to replenish water before eating? Wouldn't that dilute gastric juice and affect digestion? Western food has the steps of appetizing before meals. The reason is to use soup to stimulate appetite, lubricate the esophagus and prepare for meals. Then, hydrating before meals means the same thing. Before entering solid food, drink half a cup (about 100 ml), which can be fruit juice and yogurt at room temperature, warm crystal sugar chrysanthemum water or light tea, or a small bowl of thick appetizing soup, all of which are good ways to nourish the stomach.
3. Drink more invisible water. Some people don't seem to drink water all day long, because the water intake from food is enough to meet their needs. Food also contains water, such as rice, whose water content reaches 60%, and the water in porridge is even richer.
It is not difficult to see that the water content of vegetables and fruits generally exceeds 70%. Even if you only eat 500 grams of fruits and vegetables a day, you can get 300~400 ml of water (with two breasts). In addition, the daily diet pays attention to the combination of dry and wet, and it is not difficult to ingest 1500~2000 ml of water for three meals.
It is better to make full use of the opportunity of eating three meals to replenish water. Choose more fruits and vegetables and salty soup porridge, which has good hydration effect. 4. Remember diuretic food The so-called diuretic food refers to foods that can increase the body's water excretion, such as watermelon, coffee, tea and so on. , which contains diuretic ingredients, can promote the formation of renal urine; There are also coarse grains, vegetables and fruits containing dietary fiber, which can combine a lot of water in the intestine and increase the weight of feces; Spicy ingredients can promote the relaxation of capillaries on the body surface, make people sweat and lose water on the body surface.
Tonifying and benefiting are both means to achieve water balance in the body. 5, drinking has nothing to do with beauty, the body lacks moisture, and the skin looks dry and dull; Drinking too little water is also easy to dry stool or even constipation, and the skin is prone to acne.
Even so, the effect of hydrating on skin and skin color is limited, but now many drinks containing vitamins are all under the banner of beauty. For example, a milk-containing beverage contains vitamin B6, and its product claims to "make skin smooth and tender", but now there are quite a few beverages containing this "beauty vitamin". Orthodox monographs on nutrition have not mentioned its beauty function. Fortunately, eating more is not dangerous, but also can prevent the occurrence of coronary heart disease, which is also beneficial and harmless.
6. The "killing machine" in the boiled tap water may contain carcinogenic high chlorine compounds. If it is left for a long time (overnight), the water quality will age. Now there are also various water processors in China, similar to the once popular mineral spring pots. Such equipment has the problem of follow-up maintenance, just like drinking fountains, which may become the source of secondary pollution of drinking water.
7, the knowledge of drinking sports drinks can not make up white water before and after strenuous exercise, nor can you make up high-concentration juice, you should make up sports drinks. Sports drinks should contain a small amount of sugar, sodium salt, potassium, magnesium, calcium and various water-soluble vitamins to supplement what the body loses and needs during exercise.
Drinking white water will cause blood dilution, perspiration will increase sharply, further aggravating dehydration. The concentration of sugar in fruit juice is too high, which prolongs the emptying time of fruit juice from the stomach and leads to stomach discomfort during exercise.
Specially designed concentrations of inorganic salts and sugar in sports drinks can avoid these adverse reactions. The temperature of sports drinks is also very particular. Too high is not conducive to lowering body temperature and heat dissipation. Too cold can cause gastrointestinal spasm. Generally, it tastes cold, and the temperature is around 10.
8. Be a sad drink. Citric acid is often used as a flavoring agent for various fruit juice drinks. When you eat too much citric acid, a lot of organic acids suddenly enter the human body. When the intake exceeds the body's ability to deal with acid, it will unbalance the PH value in the body, lead to acidosis and make people tired and sleepy. Especially in midsummer, due to the hot weather and sweating, the human body will lose a lot of electrolytes, such as potassium, sodium, chlorine and other alkaline components, and a large number of sour drinks are more likely to make body fluids acidic.
Therefore, it is not advisable to drink too many sour drinks containing organic acids in summer. 9, the trap of sweet drinks If you are thirsty, the first thing that comes to mind is drinks, but this is quite dangerous.
The sugar content of cola, sprite and Fanta is 1 1%, which exceeds many fruits such as watermelon, apple and citrus. A can of 350 ml coke contains the energy equivalent to a piece of bread, a corn or 250 g fruit. The sugar content of various fruit juices is equivalent to this, even higher than it.
Pulse, her/him, activation and other vitamin drinks that look like water also contain 3% sugar. If you drink a large bottle (600 ml), it will have a considerable impact on your weight. I did hear about the unfortunate experience of someone suffering from diabetes because of binge drinking sweet drinks.
10. Disadvantages of dilute brine refers to saline with physiological concentration, and the salt content per 100 ml is about 1 g. There are several uses in daily life: one is to supplement the water and sodium lost by the body after sweating; Second, replenish the water and salt lost in the intestine after diarrhea and maintain electrolyte balance; Third, gargling with light salt water can remove bacteria in the mouth and reduce redness and swelling caused by oropharyngeal inflammation. However, light salt water is not suitable for people with poor heart function and high blood pressure, especially when blood viscosity is the highest in the morning. Drinking light salt water will aggravate dry mouth and promote blood pressure.
1 1. See through the "pattern" water purified water, and remove various microorganisms, impurities and beneficial minerals through multiple filtration.
4. How to cultivate a scientific way of drinking water
To cultivate a scientific way of drinking water, first of all, don't drink a lot of water (more than 500 ml at a time) when you are thirsty.
A large amount of water enters the body at one time, which not only affects the digestive function, but also causes reflex hyperhidrosis and increases the burden on the heart and kidneys. Secondly, when you are thirsty, don't just drink two mouthfuls of water to "quench your thirst", otherwise the water will be difficult to be effectively absorbed and utilized by the body, which will not help to alleviate the water shortage in the body.
The scientific way to drink water is to drink a whole glass of water (200 ml) slowly at a time. Old people can divide a glass of water into two times (each time 1.000 ml) and drink it slowly, which can make the body use effectively.
In addition, when drinking water with a slightly higher or lower temperature, you can put the water in your mouth first, then swallow it slowly, so that your mouth and viscera can adapt to the water temperature, and then drink it incrementally.
5. What is the scientific method of drinking water?
Water plays a very important role in human body.
So, how to drink water is correct? Many people often think of drinking water when they are thirsty, and they often gulp it down, which is wrong. Drinking water too fast and too hard is bound to swallow a lot of air together, which is easy to cause hiccups or bloating. Therefore, it is best to put water in your mouth first, and then drink it slowly, especially for people with weak stomach and intestines.
(1) Don't drink water when you are thirsty. Drink water in moderation between meals, preferably once every hour. People can also judge whether they need to drink water according to the color of urine. Generally speaking, human urine is light yellow. If the color is too light, maybe they drink too much water. If the color is dark, it means more water is needed.
In addition, after a night's sleep, people will lose about 450 ml of water and need to replenish it in time when they get up early. Therefore, drinking water on an empty stomach after getting up in the morning is good for blood circulation, and it can also promote brain lucidity and make the thinking of this day clear and agile. (2) Drink more boiled water, instead of boiling water for 3 minutes in raw water, so that chlorine and some harmful substances in water can be evaporated, and at the same time, the nutrients necessary for human body can be kept in water.
Drinking raw water is very harmful, because chlorine in tap water will interact with residual organic substances in raw water, leading to an increase in the risk of bladder cancer and rectal cancer. (3) Drink fresh boiled water, which is not only sterile, but also contains more than a dozen minerals needed by the human body.
However, if the boiled water stays too long or the boiled water in the automatic water heater is drunk overnight, it will not only lose all kinds of minerals, but also contain some harmful substances, such as nitrite. And the resulting nitrite poisoning is not uncommon. (4) The amount of drinking water varies from person to person. For human body, water is not only a carrier for transporting various nutrients, but also directly participates in human metabolism. Therefore, ensuring adequate water intake is very important for the normal operation of human physiological functions.
Usually, how much water each of us needs to drink varies with activities, environment and even weather. Drinking more water for normal people will not have much impact on the body, but it may cause increased urination and inconvenience to life.
But for some special people, we must pay special attention to the amount of water. For example, patients with edema, heart failure and renal failure should not drink too much water, because drinking too much water will increase the burden on the heart and kidneys and easily lead to aggravation of the disease. These people should listen to the doctor's specific advice on how much water to drink. For patients with heatstroke, cystitis, constipation, dry skin and other diseases, drinking plenty of water can play a certain role in relieving the disease.
In addition, people should drink more water when they have a cold and fever, because rising body temperature will cause water loss. Drinking more water can promote body heat dissipation and help patients recover. Pregnant women and people who exercise a lot consume a lot of water and should drink more water.
(5) Master the correct drinking time. Four best times to drink water in a day: the first time: I just got up in the morning, which is when blood is short of water. The second time: around 8: 00 am 8:00- 10/0, it can replenish the water lost during working hours.
The second time: around 3 pm, it is time for tea. Fourth time: before going to bed.
When sleeping, the blood concentration will increase. If you drink enough water before going to bed, it will dilute the accumulated liquid and dilate blood vessels, which is good for your health. .
6. Tips on drinking water safety
1 Don't drink water with excessive scale. Don't drink herbal tea. Don't drink water mixed with boiled water and raw water. Don't drink boiler water. Can't drink pure water all the time.

7. How to drink water scientifically and reasonably to promote health?
Water is one of the essential and easily overlooked nutrients in human body.
In fact, water is not only the main component of human body, but also has important physiological functions. Water plays an important role in regulating the metabolism of substances in the body and regulating body temperature, and at the same time, it has buffering, lubricating and protecting effects on human organs and tissues.
A large number of data show that people die faster when they are deprived of water than when they are deprived of food. You can live for weeks without food and water; But without water, it can only survive for a few days.
This shows the importance of water to life. Water is the source of all life and the basic guarantee of health. Water is the most abundant component in the human body.
The total water consumption varies with age, sex and body type. The total water consumption of adult men is about 60% of their body weight, and that of women is 50%-55%. With the increase of age, the total water consumption gradually decreases. Water demand is mainly affected by metabolism, age, physical activity, temperature, diet and other factors.
Generally speaking, the daily water source and discharge of normal people are in a dynamic balance. For an adult, the source and discharge of water are maintained at about 2500 ml per day.
The sources of water in the body include water in drinking water and food and endogenous water (metabolic water), and the excretion is mainly through the kidneys, followed by the lungs, skin and feces. Usually, the water content in each person's food is about 1 000 ml, and the endogenous water content is about 300 ml, so the daily water consumption should be about 1 500 ml.
Human health is inseparable from water, but the method of drinking water should be proper, otherwise it will be harmful to health. Clean and hygienic water is the cheapest and most effective health care product.
First of all, drink water in moderation, not binge drinking. In general, it is better to drink a small amount of water many times. Drinking a lot of water at a time will have many adverse effects on the human body. People with renal insufficiency may lead to water and electrolyte disorders in the body and even water poisoning.
Excessive drinking will increase the burden on the heart, lungs and gastrointestinal tract, causing indigestion, gastroptosis and even cardiopulmonary failure. Secondly, be regular and don't drink water when you are thirsty.
You must form the good habit of taking the initiative to drink water. Drinking a small amount of water many times in the morning can not only supplement the loss of water at night, but also promote the secretion of digestive juice and increase appetite. At the same time, gastrointestinal peristalsis is beneficial to regular defecation and lower blood pressure.
Drink boiled water instead of raw water. At present, boiled water is considered as the best drinking water. The harm of drinking raw water is well known. Raw water contains pathogenic bacteria. In addition, chlorine in water interacts with the residual organic matter in boiling water, which can produce substances harmful to human body.
In addition, drink fresh boiled water instead of "old water". Fresh boiled water, burn and drink now.
Don't drink water that has been left for a long time, boiled water that has been boiled in an automatic water heater all night, leftover boiled water that has been boiled many times, the water in a thermos bottle that day, and boiled water that has been steamed. Although these "aged water" are sterile, they boil away the inorganic salts needed by the human body, and may also contain some harmful substances, such as nitrite.
Sweat a lot. After exercise, drink warm and salty water instead of ice water. In hot summer, after sweating a lot, you can only drink plain boiled water without salt. Water entering the body can't stay in tissues and cells, and it is more likely to be excreted with sweat or urine, which may also cause hyponatremia such as palpitation and fatigue.
At this time, you should drink more salt water to replenish the lost water and salt. After hot boiled water enters the body, it will quickly penetrate into the cells, so that the body that is constantly sweating and lacking water can get timely water supplement.
Although cold drinks can bring temporary comfort, drinking a lot of iced drinks can easily lead to gastrointestinal dysfunction. In addition, eating more vegetables and fruits is also an effective way to replenish water, which not only supplements water, but also provides necessary nutrients such as inorganic salts, killing two birds with one stone.
