Description of the problem:

Drinking more water can do more good or more harm!

Answer:

Not necessarily

Asia-Pacific International Functional Water Collaboration Organization expert members of the expert tips:

■ China's adults in order to maintain a normal and healthy metabolism, on average, should be supplemented with about 2 liters of water per day, about 7 to 8 cups of water (which includes water supplemented from the diet). To develop the habit of drinking water regularly, do not wait until you are thirsty to drink water, because at this time the body is already dehydrated.

■ Drinking water to pay attention to the time and method, every day in the morning, in the middle, and at night to drink 1 to 2 cups of water, slowly drink, fine taste, you can feel a slight sweetness from it, and the urine clear long, stool through the moist, refreshing.

We often say that people can not eat for three days, but not a day without drinking water. In normal times there is a headache to the hospital to see a doctor, the end of the doctor in addition to your medication on time, will certainly urge you to rest, to drink more water. This is not only because the drug can only be dissolved in water to be absorbed by the body, and the water itself has a sedative, heat, detoxification effect. China's Song Dynasty poet Lu You, who lived more than 80 years in bumpy wandering, once wrote a poem: "Nine turns to return the Dan too many things, serving water can chase the gods." In his view to live a long and healthy life drinking water is better than alchemy.

From the perspective of drinking water and health, the mainstream scientists believe that good drinking water should meet the following requirements:

1, it should be clean, free of pathogens, heavy metals and harmful chemicals.

2. It should contain the right amount of minerals and trace elements.

3, should contain fresh and appropriate amount of dissolved oxygen.

4, should be alkaline, the water molecular group should be small, the activity should be strong.

Currently on the market, drinking water can be roughly divided into three categories, 1, pure drinking water, 2, healthy drinking water, 3, functional drinking water.

Pure drinking water: very clean, especially suitable for mixing wine, flavoring, but also drinking. In areas with poor water sources and quality, drinking pure drinking water is a better choice. We just don't advocate that children and the elderly simply drink pure water.

Healthy drinking water: mineral water that meets the standard is good, in addition to tap water after deep processing (such as precision filtration, activated carbon adsorption, ultraviolet sterilization, etc.) and the mineralization of the activation of the pure water after treatment can be called healthy drinking water.

Functional drinking water: is a newer variety of drinking water, it requires water in the clean basis and then after physical processing, so that the water molecule group becomes smaller, alkaline pH for alkaline, the water redox potential is reduced, and even for the negative potential. Functional drinking water has anti-fatigue, antioxidant, blood lipid regulation. What is remarkable is that these health effects are produced without additives (drugs and nutrients). In addition to general drinking water, it is more suitable for middle-aged and elderly people and target groups (such as busy work, excessive stress, over-nutrition) to drink.

1 experts teach you to distinguish between drinking water "quality"

● Pure water: after the membrane separation filtration device of the drinking water, which on the one hand, filtered out the harmful substances in the water, and on the other hand, filtered out the minerals and trace elements beneficial to the human body.

● Water purification: drinking water filtered by activated carbon, etc., in the filtering of harmful substances at the same time as the minerals and other beneficial elements to be retained, but the filter core must be kept clean, regular replacement, in order to ensure that the water "quality" of stability.

● Mineral water: extracted from the deep underground flow through the rocky groundwater and after a certain treatment of drinking water, to contain certain minerals and trace elements as a distinctive feature of the human body's metabolism.

Mineral water is good and bad to identify: the trademark printed on the ion content in the water, generally high calcium and low sodium collocation for the top, in addition to the labeling of magnesium, potassium, sulfate and other trace elements content for the best.

● Mineral water: mineral drinks are not mineral water, minerals are artificially added, there are difficulties in the proportion, the nutritional value is not as good.

● Mountain spring water: mountain spring water is not mineral water, because the country does not yet have a relevant standard, "body" is not stable

● Oxygen-enriched water: Oxygen-enriched water is artificially filled with oxygen, the dissolution of oxygen in the water is saturated, not the more the better.

● distilled water: water in the boil to 100 degrees Celsius boiling point, in the high temperature sterilization at the same time, some of the boiling point less than 100 degrees Celsius of harmful substances will remain, such as the boiling point of 70 degrees Celsius carbon tetrachloride can not be filtered out.

"Safety is not the only criterion, people in the choice of long-term drinking water should pay more attention to whether it is beneficial to human health," China Medical Promotion Association Health Drinking Water Professional Committee executive director Niu Xiaoying that "does not contain harmful substances of pure water is very clean, drinking, although safe, but the long-term drinking is not beneficial to the human body. Long-term drinking is not beneficial to the human body. To judge the health of the water "body" is more important, the hardness of the water is weak alkaline, which contains macronutrients and trace elements and the size of the water molecules.

Although experts agree that mineral water is the crown of drinking water, but there are many questions around the mineral water. Such as "why mineral water to drink up a strange taste", "why use mineral water bubble tea will be red" ...... In the face of the many questions, Fudan University, Public **** School of Health, Professor Zhu Huigang Explanation, different sources of mineral water extracted from the "body" there are differences.

At present, the national standard for mineral water is only a restriction on the access of mineral water producers, and there is no source of different groundwater "body" to make a more detailed evaluation. Such as in Japan, in addition to national standards, mineral water also has a delicious and healthy two indicators, used to give different tastes of consumers to provide the convenience of shopping. For example, if the mineral water health index is flat, the flavor index is high, while some are health index is very high, the flavor index just pass, which may be helpful to guide consumers to drink.

1 experts put forward seven standards of healthy drinking water

In September 2003, the first Tianjin Science and Technology Academic Exchange Month activities, experts put forward seven standards of healthy drinking water.

※No poisonous, harmful and foul-smelling substances;

※Moderate hardness;

※Moderate content of minerals needed by the human body;

※PH is slightly alkaline;

※Moderate content of dissolved oxygen and carbon dioxide in the water;

※Water molecules;

※Water physiological function is strong.

Expert tips

Adults should drink water no less than six times a day.

Children and teenagers should ensure that they drink about 1000 ml of water a day.

Drinking freshly boiled water should not be too hot, generally 25 degrees Celsius to 30 degrees Celsius is appropriate.

When you have a fever, drinking more boiled water can improve resistance, eliminate sweat, more urine, in addition to lowering body temperature, but also eliminate toxic substances in the blood, so scientific drinking water will make people benefit.

1 How to drink water is considered "scientific"?

Drinking water although everyone will, but how to drink water is considered "scientific"?

Drinking water in the "health diet" plays an important role, "scientific" according to the body's physiological requirements to arrange the number of daily water, time and method. This has a great deal to do with human health.

People drink water, generally often based on whether it is thirsty, which is unreasonable. Because thirst indicates that the human body has lost its balance of water, is the body's cell dehydration has reached a certain level, the central nervous system issued a signal to replenish water. Drinking water after the thirst, equal to the soil cracked before irrigation, is not conducive to the growth of plants.

It is advisable to drink water on an empty stomach before meals

The average daily consumption of water in the human body (through the respiratory tract, urine and feces, skin, etc.) is about 2500 ml, in addition to the body's metabolism of substances that can be oxidized to produce 300 ml of water, every day, at least 2,200 ml of dietary supplements to reach a balance.

How should this 2200 milliliters of water be scientifically supplemented to the body?

In short: drink water on an empty stomach before meals, and have soup and water during meals.

Drinking water on an empty stomach before meals means that you should drink a certain amount of water about an hour before your morning, afternoon and evening meals. Because, the digestion of food is accomplished by the digestive juices of the digestive organs. The total amount of digestive fluids (saliva, gastric fluid, bile, pancreatic fluid, intestinal fluid) secreted per day amounts to about 8,000 milliliters. Drinking water on an empty stomach before meals, water in the stomach only stays 2 to 3 minutes, it will quickly enter the small intestine and be absorbed into the bloodstream, an hour or so can be supplemented to the whole body tissues and cells, supplying the body's need for water.

So, drinking water before meals can ensure the secretion of necessary and sufficient digestive juices to promote appetite, help digestion and absorption, while not affecting the physiological water content of tissue cells.

Also, therefore, it is important to hydrate before meals. Especially before breakfast, because sleeping overnight, longer, the body loses more water, wake up in the morning, drink more water is very important.

Warm boiled water on an empty stomach

Warm boiled water on an empty stomach is preferable, but also light drinks such as juice, light tea, vegetable juice and so on. Milk, soy milk, eggs and other supplemental nutrition should not be consumed on an empty stomach, but should be placed in the meal or eat after the meal. The heat of the day sweating, should be discretionary to increase the amount of water to drink; after a lot of sweating should be supplemented with some very light salt water.

Drinking soup with meals helps dissolve food

Strong tea and salt water can not replace the fasting water, because strong tea has a diuretic effect, affecting the body's water balance, can cause cellular dehydration. Salt that is, sodium chloride, due to the low sodium content in the cells, when we drink salt water, salt water can enter the blood and tissues, but can not enter the cells, too thick, but cause cellular dehydration, which is not good for the human body.

On the other hand, why is it important to have soup and water at meals?

Because, a certain amount of soup and water at meal time helps to dissolve the food, so that when the stomach peristalsis, the food and gastric juice will be stirred for preliminary digestion, and supply more water to facilitate the digestion and absorption of food in the small intestine.

If you don't add the right amount of water before and during meals, when the body fluids lose water when the gastric juice is secreted in large quantities after meals, it is bound to cause thirst. This time then drink water, it will dilute the gastric juice and affect digestion, but also due to drink too much water and increase the burden on the heart and kidneys.

1 children and water

Children and young people should not drink pure water for a long time

With water fountains and pure water, it seems to become much more convenient to drink water, but most people can not imagine that we drink a kind of water is not nutritious, functional degradation of the water, pure water drink too much on the children and young people's harmful effects.

Water nutrition expert Prof. Li Fuxing introduced, pure water in the production process to remove harmful substances in the water at the same time, but also filtered out the trace elements in the water. He pointed out that children and teenagers calcium needs 30% from water, long-term drinking pure water, this part of the source of calcium is gone; in addition, the calcium in the food than the water to come to the slow absorption of calcium, to be much lower. Children drink such water for a long time, not only can not replenish calcium, zinc and other trace elements, the body has the minerals will be absorbed by the pure water discharged from the body.

Not long ago, the Consumer Council officially issued a consumer alert, children and the elderly should not drink long-term pure water. Consumers should also be reminded that the barrel sealed pure water, once opened and air contact, 24 hours later, began to breed bacteria. Therefore, it is not advisable to drink a bucket of pure water for several weeks. (Beijing Times, October 27, 2003)

Children's beverages are preferred to plain water

When all kinds of beverages fill the counters of major shopping malls, some experts at home and abroad are also very interested in the study of the activity of warm water. Studies have shown that warm water can improve the activity of lactate dehydrogenase in the organs, which is conducive to the faster reduction of the accumulation of "fatigue factor" in the muscles - lactic acid, thereby eliminating fatigue, renewed spirit. The physiological function of water on the human body has four main aspects:

1. Human tissue and cell nutrients and metabolites in the body to run, all need water as a carrier.

2. Water can regulate body temperature, so that the body temperature does not fluctuate too much.

3. Water is a lubricant for friction between human tissues.

4. Water has a strong solubility, a variety of inorganic and organic substances are soluble in water, the body's metabolic waste in the role of water is easy to remove to the outside of the body.

Therefore, experts emphasize that children's drinks preferred plain water.

Children's diarrhea, fruit juices cause trouble

In the pediatric outpatient clinic, from a few months old babies to teenage schoolchildren have come to see the diarrhea. A 4-year-old boy's mother told the doctor, the child's diarrhea for almost a week, loss of appetite, weight loss, take any medicine are not obvious. The doctor was asked to learn that the child usually drink juice as water, at least two or three bottles a day, diarrhea after illness, do not want to eat, but the juice did not stop drinking. Diagnosis of parents full of doubt, originally thought that drinking fruit juice will let the child more access to vitamin C, do not think that fruit juice will become an accomplice to diarrhea?

The doctor explained that most parents nowadays mistakenly believe that juice drinks are nutritious, in fact, not scientific. Juice drinks contain a variety of vitamins, sugars, appropriate drink can be supplemented with vitamins and inorganic salts in the body, but for the digestive system is not too sound for children, drink too much juice drinks will cause disease. Juice drinks are hypertonic liquids, first of all, it can not quench thirst, the more you drink the more thirsty you are. Secondly, the main organic component of juice drinks is sugar, consuming too much sugar will disturb the child's digestive and absorption function, inhibit appetite and affect the absorption of protein and other nutrients. Once the child has developed the habit of drinking fruit juice, but lead to malnutrition, hindering normal growth and development. At the same time, a large amount of sugar in fruit juice can not be absorbed and utilized by the body, easy diarrhea. Sugar from the kidneys when excluded, will make the urine changes, urine sugar value increases, time will also cause kidney disease.

Pediatric experts advocate that children supplemental water or white water is good. If you drink fruit juice, it is best for parents to squeeze some pure fruit juice for their children to drink.

Drinking water in the middle of the night can prevent disease

Medical personnel have been grouped on the elderly study, a group of people up in the middle of the night to drink 250 milliliters of boiled water, the other group slept until dawn, and then in the early morning to determine their blood concentration. The results found that drinking water group of people blood concentration significantly lower.

The vast majority of cerebral thrombosis is detected early in the morning when they wake up, and the sudden onset is mostly in the middle of the night. The elderly due to physiological aging and other factors, most have varying degrees of atherosclerosis and other cardiovascular diseases, blood viscosity is also higher. Lack of water at night will make the blood viscosity rise, platelet coagulation hyper, so that the original atherosclerosis of the blood vessels are more likely to produce embolism, when the embolism off in the cerebral arteries, coronary arteries and their branches, then ischemic stroke or myocardial infarction occurs.

The elderly drink more water to prevent skin aging

Once a person to the middle and old age, intracellular water will be reduced than the youth period of three to four times as much, but also because of this, in the middle and the elderly, most of the skin will be wrinkled, if you can not adequately replenish water, not only the skin wrinkled situation is serious, but also affects the normal operation of the urinary tract!

According to foreign studies, people are used to drinking water when they are thirsty, but in middle age, the feeling of thirst becomes less and less obvious with age; older people tend to drink water when there is a clear lack of water, and the demand for drinking water is not strong, so, especially when the temperature rises suddenly or when a heat wave strikes, heatstroke or other accidents are particularly common, and there is even a case of "heat exhaustion". The newest addition to the lineup is the newest addition to the lineup, the newest addition to the lineup, the newest addition to the lineup, the newest addition to the lineup.

In fact, there are many ways to replenish water, and many dietitians suggest that you can boil fruits and vegetables in soup, drink tea (strong tea is not suitable), and cool water. Special attention is paid to the morning after getting up if you can first drink a cup of cold water, the body is very helpful; because the human body after a night's sleep, water from sweating, urination and breathing in the consumption of a lot of blood, blood has become thick, blood vessel lumen is also due to the reduction of blood flow and narrowing, which will be easy to cause cardiovascular embolism and other accidents. The newest addition to the lineup is the newest addition to the lineup, the newest addition to the lineup, the newest addition to the lineup, the newest addition to the lineup.

As for the amount of water to drink, it depends on the condition of the individual, and it is best to drink a little more. The more hygienic choice is to drink cool water, salt water, tea or fresh mineral water. Of course, each intake of water should not be too much, so as not to increase the burden on the heart and kidneys; secondly, the same as normal people, middle-aged and elderly people after labor or exercise, although a lot of sweat, but also not suitable for drinking too much.

The old man should drink some water even if he is not thirsty

The old man after the step of people after the flower armor, the water in the body will gradually decrease with age, showing chronic dehydration phenomenon. If the skin cell water is reduced, will make the subcutaneous tissue and elastic tissue reduction, sebaceous gland secretion of water is reduced, the skin becomes dry, wrinkles increase; water shortage will also affect the saliva, bile, gastric secretion, the old man will feel depressed, digestive dysfunction, constipation and so on. Therefore, in order to live a long and healthy life, the elderly should develop the habit of drinking water every day even if they are not thirsty. Every day to 1000 ~ 1500 ml is appropriate, in the daily meal half an hour before drinking can increase appetite, but also beneficial to the elderly's general health. Generally speaking, in the winter and spring seasons, the climate is cold and dry, the elderly are prone to colds and flu, and it is easy for the body to become dehydrated due to fever, coupled with the reduction of water intake in winter, the elderly in the winter and spring easily lead to a lack of water in the body. In summer and fall, people sweat more, and if they cannot replenish water in time, it is also easy to cause dehydration of the body. In addition, in all seasons of the year may eat unclean food and cause diarrhea, the result can also lead to serious dehydration in the body of the elderly, so in diarrhea should pay attention to drink more water.

The best time to drink water for the elderly

Bedtime

According to expert research, the elderly night before going to bed without drinking water, which can lead to plasma concentration, blood viscosity increased and platelet coagulation hypercapacity, which can promote thrombosis in the body. For the elderly or people suffering from cardiovascular ischemic disease, drinking a glass of water before going to bed at night can prevent fatal infarction. Many older people are not accustomed to drinking water before going to bed, for fear of getting up at night to urinate. In fact, the elderly bladder atrophy, the capacity to reduce, do not drink water as usual to get up and urinate.

The middle of the night

The elderly due to renal contraction function decreases, the night urine, which leads to a lack of water in the body, easy to make the blood flow viscous, cardio-cerebral blood flow resistance increases, easy to cause cardio-cerebral vascular disease. For the elderly suffering from cardiovascular and cerebrovascular disease, due to changes in the endothelium, blood viscosity is high, easy to form an ischemic stroke, the lack of water at night increases the risk. Therefore, it is important to drink water in the middle of the night.

Getting up

The elderly sleep at night, due to urination, sweating, breathing, the body is relatively dehydrated, resulting in blood concentration, slow blood flow, the body metabolite accumulation. Drinking a cup of water after getting up can make the blood circulate normally, and have the effect of preventing hypertension, cerebral thrombosis, myocardial infarction and other diseases. Running after drinking water is more beneficial. Moisture can make the gastrointestinal tract to keep clean, but also help the liver detoxification and kidney, endocrine function improvement, improve immune function, prevention of colds, laryngitis, arthritis and certain skin diseases.

Drinking water can lose weight

Clear water helps burn calories, the simplest way to lose weight is to drink 8 glasses of water a day.

Drinking water can lose weight? A lot of people for food calories, calories and weight of these figures and worry, German scientists have found a may be the simplest way to lose weight, is to drink 2 liters of water every day, can help consume calories, to achieve the effect of weight loss.

However, dietitians are cautious about this "new" discovery, and emphasize that weight loss should also pay attention to balanced nutrition, and drinking 2 liters of water a day is indeed a healthy way to help the body's metabolism.

A study at Charite University in Berlin, Germany, found that those who followed the health recommendation of drinking 2 liters of water a day (about 250 milliliters per glass, or about 8 glasses) burned an extra 150 calories a day. According to Michael Boschmann, the professor who led the study, water *** sympathetically regulates metabolism, increasing the efficiency of the body's metabolism and achieving the effect of burning more calories.

The study appears in the latest issue of the Journal of Endocrinology and Metabolism, but the researchers emphasize that only drinking water has the effect of burning extra calories, and that drinking aerated water and other beverages has the opposite effect.

Elaine Wong, a registered dietitian at St. James' Settlement in Hong Kong, pointed out that because water is zero-calorie, drinking it certainly does not make people obese.

But Emma Wong emphasized that although water is zero calorie, but do not encourage to drink only water to lose weight, because it will affect the physiological function and disturb the metabolism. (Worker's Daily Tianxun Online)

The woman made of water Q&A

Water is not omnipotent, but without water is not at all possible. In the cold and dry season smooth skin is the highest index of beauty. Moisture in the end can play how much beauty effect? Are topical hydration products more effective than drinking water? Are there skin problems that can be solved by drinking water? We answer for you -

People who drink more water than those who drink less skin lubrication, so drinking water can make dry skin become smooth! Wrong Skin becomes dry in winter is due to simultaneous loss of moisture and oil on the surface of the skin, to effectively address dryness you need to apply lotion with moisturizing properties in a timely manner. The only way to solve the problem is to drink water.

In winter, you don't sweat much, so you don't consume much water, so you don't have to drink 8 cups of water a day? Wrong We burn about 2,000 calories a day, and for every 15 calories you burn, you need to lose a spoonful of water. Eight glasses of water a day is just enough to replenish the daily loss. And drinking water carries away waste and toxins from the body; people who drink enough water suffer less from skin problems than those who drink less. That's why you shouldn't cut down on your water intake in winter either. In summer, when you sweat a lot, it is necessary to consciously increase the amount of water you drink.

Drinking more water can eliminate dark circles! There are two reasons for the formation of wrong dark circles. First, the influence of genetic factors, lack of sleep, colds or sensitivity. Second, poor blood circulation. But drinking more water does not promote blood circulation and make dark circles disappear.

Punctures and hard skin on the nails are a sign that your hands are dehydrated! In addition to specialized hand creams and novelty gloves that can moisturize your hands and soften your hangnails and knuckle lines, you can rub your hands with two spoons of honey, a spoonful of almond oil, and a spoonful of lemon pulp. Rub for a few minutes and then wash off with warm water for a deep moisturizing effect. Also, applying petroleum jelly to dry areas before going into the bath is more effective than applying it afterward. Cutting the hard skin around the nails is not the best solution. In addition to using a special softening oil, rubbing with a mixture of egg yolk, pineapple juice and vinegar can soften the hard skin, but it takes a long time to get results.

To "face" please "drink water"

"My face has been dry lately, what is good to use?" "The skin of the face has become sensitive, sometimes there are small red bumps, and even itchy and painful, what should I do?" Spring is coming, many cosmetic counter can often be heard in front of such inquiries. The face of the matter can not be sloppy, not only women, many men also want to pick the right skin care products to make their face light.

According to professionals, the human body is active in the spring, sebaceous gland secretion, the skin does not lack of oil, feel dry because of the lack of water. With the moisturizing effect of skin care products, such as moisture balance products, moisturizing liquid, cream, gel, etc. is essential, while avoiding the purchase of oily ingredients large skin care products. In addition, spring is dry and windy, ultraviolet rays are also very strong, sunscreen products should also be used, may also want to do deep skin care.

If there is no time or shyness can not patronize the beauty salon, at home with a humidifier or simply play a pot of boiling water, so that the steam fumigation face, and then use a towel wrapped around the face for 10 to 15 minutes after the face will feel very comfortable.
