Drinking plenty of water has many benefits, especially getting up early in the morning and drinking a glass of water half an hour before going to bed, which benefits you endlessly every day all year round!

Everyone knows that drinking water is good for your health, but how much you drink is also worthy of attention, especially for people with kidney problems or poor metabolic status (such as people who are prone to edema), so you should be particularly cautious about water intake. In the past, there have been reports of drinking water and drinking water poisoning due to not knowing the physical condition and taking a large amount of water at one time.

Water intake varies from person to person. Basically, the average person's daily drinking water is suggested to be 30~70 times of body weight. The following is a simple algorithm: take a person weighing 50 kg as an example, and the basic water intake is 50 kgx30 =1500 cc; Those with normal metabolic function can be increased to 50 times, that is, 50 kg X50 = 2500cc；; If you have good metabolism and exercise habits, you can increase it to 70 times, that is, 50 kg x70=3500cc.

However, if your metabolism is poor, it is best to control the amount of water you drink every day within 30 times of your weight at first. People who are prone to edema suggest not to drink water for three hours before going to bed.

The disadvantages of drinking more water:

It is not advisable to drink more water for half an hour after a meal.

It is best not to drink a lot of water half an hour after a meal, so as not to dilute gastric juice, dilute gastric acid and damage digestive function. Drinking water after meals and soup between meals can mix digestive juice with food, which has a good effect on digestion and absorption. However, it is unscientific for some people to drink plenty of water after meals.

After people eat, food occupies most of the space in the gastrointestinal tract. Drinking plenty of water will fill the stomach and make people feel bloated. In addition, if people eat too much and drink a lot of water, the food in their stomachs will be heavy and their stomachs will sag or swell.

Drinking too much water after meals will dilute the concentration of gastric juice and affect the digestion and absorption of food. The human stomach can secrete about 1.5~2.5 liters of gastric juice every day, which contains about 0.4%~0.5% of gastric acid, and the chemical component of gastric acid is hydrochloric acid. Hydrochloric acid can dissolve protein, digest foods containing calcium and iron, and kill bacteria that enter the stomach with food. If you drink a lot of water after a meal. Dilute gastric juice. The ability of hydrochloric acid to digest food is weakened, and the bactericidal power is also weakened. It can be seen that it is best not to drink water or drink less water after meals.

Chinese medicine believes that people with these three constitutions should not drink more water.

Traditional Chinese medicine divides the constitution of ordinary people into nine categories, and people with different constitutions have different characteristics and diets. Among them, people with qi deficiency, yang deficiency and phlegm-dampness constitution should not drink a lot of water, otherwise there will be symptoms such as abdominal distension, loss of appetite and diarrhea, and severe symptoms such as dizziness, vomiting, pale mouth and sparse saliva.

Qi deficiency is manifested as mental fatigue, laziness, easy sweating, pale mouth and unwillingness to drink water. The tongue is pale and has teeth marks on the edge.

Yang deficiency is manifested as: fear of cold, cold hands and feet at ordinary times, especially when it is cold. People like to eat hot food, don't like cold drinks and cold food, or feel uncomfortable after eating, so they may have diarrhea. Usually the stool is rotten, it is not easy to form, urine is long, and some people have more nocturnal urine. The tongue is light and fat, with teeth marks on the edge and moist tongue coating. Some people even seem to have a layer of water on their tongue.

Phlegm-dampness is characterized by dark yellow complexion, mild edema of eyes and more oil on facial skin. People with this constitution sweat a lot, sweat is sticky, their mouths are sticky or they feel sweet. One thing is easy to distinguish, that is, people with this constitution often feel very tired and sleepy, especially in the waist and legs, sometimes they feel chest tightness and are prone to expectoration. This kind of person has turbid urine.

The same characteristics of people with these three constitutions are: 1. They don't like drinking water, even if they drink water, they like drinking hot water. 2, usually prefer to eat something a little hotter, many people like to eat ginger, or feel very comfortable after eating ginger soup and ginger rice.

Solution: People with qi deficiency, yang deficiency and phlegm dampness can still drink some water if they feel thirsty, but don't drink a lot at a time, you can drink it slowly several times. However, they may not feel thirsty all day, so don't drink water completely. Consider drinking tea instead of water. People with yang deficiency can drink some Pu 'er tea or fry some ginseng soup instead of water. People with qi deficiency will use Atractylodes macrocephala or Codonopsis pilosula to cook soup instead of water; People with phlegm and dampness use coix seed or lentils to cook soup without water.

If the heart is not good at drinking water, it is advisable to drink a small amount of water many times.

In the health care principle, many people advocate drinking more water to promote metabolism in the body. However, experts warn that people with bad hearts should not drink more water, otherwise it may aggravate the heart load and even lead to diseases.

Experts point out that many heart patients are found to drink a lot of water every day, which is actually very dangerous. Because a large amount of water enters the human body and is absorbed, it will lead to a significant increase in body fluid volume, which will dilute blood and increase blood volume, thus increasing the load on the heart, and the heart has to increase the intensity and speed of blood delivery. It is not a big problem for normal people to increase the workload of the heart, but for heart patients, their originally unsound hearts are often unable to bear such changes, so it is likely to induce or aggravate the condition.

Therefore, experts suggest that patients with bad heart should drink a small amount of water many times, and never drink a lot of water at a time, so as not to increase the burden on the heart.

Many people think that you should not only drink water when you have a cold, but also drink more water. But not all cold patients should drink more water, which is not suitable for infants who have been ill for less than 6 months.

Medical experts at Johns Hopkins Children's Medical Center in Baltimore, USA believe that infants under 6 months should not be fed too much water to avoid symptoms of water poisoning. Children over 6 months are not subject to this restriction.

Under normal circumstances, doctors will advise patients with colds to drink more boiled water, because colds are viral infections or secondary bacterial infections. Drinking more water helps to increase urine output and indirectly eliminate toxins in the body, especially when urinary tract infection occurs, which is beneficial to flushing bladder and rehabilitation.

However, drinking more water is not recommended for cold patients with severe virus infections such as bronchitis and bacterial pneumonia. Because drinking more water will increase the secretion of antidiuretic hormone, because it can retain liquid by stimulating the kidney collection tube to reabsorb water. If extra liquid is given when the secretion of antidiuretic hormone increases, it will cause excessive water in the body, electrolyte imbalance, and may cause symptoms such as hyponatremia and excessive liquid load.

Keep drinking water after a cold, but don't drink a lot at a time. Drink water intermittently. Drink about one cup at a time, no more than 300 ml, and then drink it after a while. Don't drink one cup after another, it's too heavy for the kidneys. The amount of drinking water a day should not exceed 2000 ml. This can not only maintain the demand for drinking water for the common cold, but also have no effect on respiratory tract infection.
