People cannot live without water for a moment. It is the carrier of nutrient metabolism, allowing nutrients to exist in liquid in the state of dissolved or electrolytic ions, which is convenient for transportation, exchange and storage. For example, an adult can secrete up to 6 ~ 8 liters of digestive juice every day, of which about 99% is water. In the small intestine, food is finally decomposed into absorbable small molecular nutrients by various enzymes, dissolved in water, and then passes through the small intestine wall through various channels of the body and enters the blood.
90% of human blood is water, and blood transports nutrients to all parts of the body. At the same time, it also carries wastes and toxins produced by all cells in the body, and finally it is excreted through a specific purification and excretion system. Water is not only the raw material of various metabolic reactions in our body, but also the product of biochemical reactions.
Drinking water is so important, what is the "correct posture" for drinking water? Each of us has strict and meticulous intake standards at different ages. It can be roughly divided into the following categories:
From 6 months to 1 year, the total daily drinking water is 900 ml (milk/food+drinking water).
1~2 years old, the total intake is 1300ml (milk/food+drinking water).
2 7 years old, drinking 600 800 ml every day.
7~ 10 years old, drink 1000 ml every day.
The daily drinking water for adults should be between 1500~ 1700 ml.
However, lactating women need to drink about 2 100 ml of water every day.
In addition, it should be noted that for people who consume more water by manual labor or working outdoors or when the temperature is high, the amount of drinking water should be increased as appropriate. However, for some special cases, such as kidney disease, liver disease, congestive heart failure and so on. On the contrary, you should not drink more water, which may cause water poisoning. You should take a proper amount of water according to the doctor's advice. For normal people, the renal excretion ability is normal, and water poisoning rarely occurs. I would like to remind people with poor kidney and heart function to consult a doctor in time when drinking water.
Ordinary people drink 1.500ml ~ 1.700ml (female 1.500ml, male 1.700ml) every day, about 7 to 8 cups. For people who work or exercise in a high temperature environment, they sweat a lot and need to increase their drinking water appropriately. When necessary, normal saline (concentration of 0.9%) should be supplemented as appropriate. Athletes, farmers, soldiers, miners, construction workers, firefighters and other high-level professionals should also increase water or consider physiological saline.
The best time to drink water
Distribute it evenly at any time of the day, drink it at any time, and don't wait until you are thirsty. It is especially good to drink a glass of water on an empty stomach after getting up in the morning. You can also drink a glass of water before going to bed, but don't drink too much before going to the toilet at night to avoid affecting your sleep.
Best method
A few times, each time about 200 ml (1 cup), don't concentrate on pouring a large glass of water at a time, because there is a large amount of water at present, which may accelerate urine excretion. In addition, when the water in the body reaches balance, it can ensure that the digestive juice is secreted sufficiently during meals, stimulate appetite and help digestion, while drinking a lot of water at one time will increase the burden on the gastrointestinal tract and dilute the gastric juice, which not only reduces the bactericidal effect of gastric acid, but also hinders the digestion of food.
In addition, when participating in sports, the water loss in the body is accelerated and needs to be replenished in time. When the intensity of exercise is high, we should pay attention to the supplement of water and minerals during exercise, and replenish enough drinking water in time as needed after exercise.
Drinking more water can benefit us for life. From now on, everyone should drink an extra glass of water every day to bring health closer to us.
