Water is the source of life, and 70% of the human body is made up of water. Water is not only a solvent, detergent and lubricant, but also a coolant and buffer in human body. Because of the existence of water, the life processes of human body such as nutrition transportation, food digestion, body temperature regulation, waste excretion and body fluid circulation can be carried out smoothly. Once people are dehydrated, it will cause constipation, dry skin, fatigue, hunger, headache, dizziness, lung, urinary tract infection, joint stiffness and other diseases. In order to ensure normal physiological metabolism, a person must drink a proper amount of water every day.
However, some experts pointed out that the "source of life" is devouring people's health because of improper drinking methods and neglect of drinking safety. According to statistics of relevant UN agencies, 80% of human diseases are related to improper drinking water. Diseases such as diarrhea, trace element deficiency, dysentery and even cancer may all be caused by improper drinking water for a long time.
Water is very important to people, but people don't know how to drink water and what water to drink, which makes them sick.
So, how can we drink water correctly and drink the right water?
It is best to drink alkaline water.
At present, distilled water, space water, ionized water, electrolyzed water, oxygen-enriched water, purified water and other aquatic products are flooding, but these aquatic products are too pure and soft. For example, distilled water is mainly used in medicine and is not suitable for people to drink at all. Drinking soft water for a long time is easy to get cardiovascular diseases.
Experts suggest that drinking well water or tap water with certain hardness, certain dissolved solids and alkaline pH value is beneficial to human health. The so-called dissolved solids are indicators used to measure the amount of minerals contained in water. Well water and tap water with certain hardness and soluble solids can not only be well absorbed by human body, but also prevent human body from absorbing toxic and harmful substances, thus reducing the harm of these substances to human health.
Alkaline water can especially reduce the mortality of cardiovascular diseases. The harder the quality of drinking water, the lower the mortality rate of heart patients. Some British medical scientists have found that the mortality rate of cardiovascular patients in soft water areas is higher than that in hard water areas 10 ~ 15%.
However, the water quality is too hard. Scientific research shows that the hardness of drinking water is generally 50 ~ 200mg/L (calculated by calcium carbonate), and the ideal hardness is about170 mg/L. ..
How to drink water
Really effective drinking water can make the body really absorb it effectively. Try the following methods.
Drink a glass of water in one breath.
The really effective way to drink water is to drink a whole glass of water (about 200 to 250 ml) in one breath (or at a time), so that it can be truly absorbed and utilized by the body. If you just take a sip or two to quench your thirst, it won't help your health at all.
Drink good water.
Try to avoid drinking distilled water often, because the water in distilled water is too acidic, which is easy to cause harm to the body, especially to people with weak kidneys. You can choose high-quality mineral water If conditions permit, drinking alkaline water is most beneficial to the human body.
Drink boiling water
In hot summer, many people will choose to drink ice water. In fact, ice water is not good for the function of the stomach, and drinking warm water is more beneficial because it helps the body to absorb it.
Drinking on an empty stomach
Of course, you can drink water at any time. If you are thirsty, you can only quench your thirst, but it doesn't help. The effective way to drink water is to drink it on an empty stomach, and the water will flow directly from the digestive tract and be absorbed by the body; Drinking water after meals is not as good as drinking water on an empty stomach.
Can be released and received.
People who go to work often ignore drinking water because of their work. I would like to remind all my friends not to drink water on the grounds of "going to the toilet often". In this way, the bladder and kidneys will be damaged, which is easy to cause backache.
How much water do you drink every day?
Most people think that drinking 8 glasses of water every day? 2000 cc is good for health. But in recent years, some foreign medical research departments have put forward different opinions. Many experts point out that it is not necessary to drink 8 glasses of water every day, because drinking too much water will also bring trouble to the body.
Experts believe that drinking water is the same as taking calories, and you should supplement as much as you need. At present, there is no scientific evidence that drinking more water can detoxify more. On the contrary, if a person drinks too much water, he will easily lose the electrolyte balance in his body? A large number of sodium and potassium ions are lost, water-soluble vitamins? For example, groups B and C are more likely to be lost.
How much water is appropriate for normal people to drink every day? Scientific research has found that, generally speaking, the water lost from urine, sweat or skin evaporation is about 1800 ~ 2000 cc, so people have been saying for many years that healthy adults need to supplement about 2000 cc of water every day. But this 2000 cc water is not necessarily obtained by drinking water, and the moisture in food should be counted together, which is the correct health care method.
In fact, the food we eat every day contains a lot of water. For example, most vegetables and fruits contain more than 90% water, while eggs and fish also contain about 75% water. Roughly speaking, we can get at least 300 ~ 400 cc of water from food or soup when we eat a meal. So after deducting 1000 ~ 1200 cc of water from food for three meals, we only need to drink 1000 ~ 1200 cc of boiled water every day, with an average of 2 cups in the morning and 2 cups in the afternoon, which is enough. However, we should also know that the demand for water must depend on everyone's environment? Temperature, humidity, exercise, health and food intake. , there is no definite standard value.
Experts believe that the general principle of drinking water is: not less than 500 cc per day, but not more than 3000 cc. People who need to drink more water, such as patients with gout and kidney calculi, should follow the doctor's advice.

Some people will drink a large glass of boiling water after getting up in the morning. It is said that this can prevent constipation and clean the intestines. Some doctors also think that drinking only boiled water in the morning is not enough.

Don't step into five misunderstandings when drinking water.
According to the latest survey, there are many misunderstandings about drinking water at present.
Professor of Health Drinking Water Professional Committee of Chinese Medical Association recently reminded that drinking water should not step into five major misunderstandings.
1, one-sided emphasis on minerals in water. Mineral water is deeply loved because it contains some minerals needed by human body. Many consumers think that the higher the mineral content, the better, but it is not. Drinking water should contain appropriate and balanced minerals, but when the mineral content in water exceeds the standard, it will endanger human health.
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 lead to malnutrition. Drinking a lot of pure water will take away useful trace elements in human body, reduce human immunity and easily cause diseases.
Drink water just to quench your thirst. It is generally believed that people only drink water when they are thirsty. The survey shows that 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, so as to facilitate human absorption.
4. Beverage equals drinking water. Some people like to drink as drinking water. In fact, water and drink are not functionally equivalent. Because the beverage contains sugar, protein, essence and pigment, 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.
5. Use medical water 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.
