Benefits can more effectively promote detoxification, promote metabolism, brighten eyes and moisturize skin. Drinking tea in moderation every day can reduce the incidence of bladder cancer, prostate cancer and urethral carcinoma by nearly 20 percentage points ... The disadvantage is that the appropriate time for drinking water is always ignored, as my friend upstairs said; It is also good not to drink water for two hours before going to bed (affecting sleep), not to drink water for half an hour before and after meals (beneficial to the stomach), and to get up in the morning and drink a cup of warm water (the reason is not detailed). In addition, drink slowly and take a sip of water. Don't overeat! Water is a component of body cells, which not only fills the whole tissue cells of the body, but also is the main liquid to maintain the normal concentration of body fluids in the body. At the same time, every process of food digestion, absorption, nutrient transportation and utilization needs the participation of water; After digestion, absorption and metabolism, the remaining food residues and metabolic wastes also need the help of water to be excreted smoothly. In addition, water has other functions, such as lubricating joints, avoiding friction between bones, providing mucus secretion matrix, lubricating gastrointestinal tract, respiratory system and urinary tract, and balancing body temperature. This shows the importance of water to human health. If the body loses 15% to 20% of its weight, it will stop its physiological function and even die. In summer, many people are used to using sports drinks as a source of water supplement. In fact, although the body will excrete a lot of electrolytes when sweating during exercise, the yin organs will automatically adjust to reduce the electrolyte discharge in urine to maintain the stability of the body. Although sports drinks can replenish electrolytes lost in sweat, they contain sugar, which will prevent liquid from flowing from the stomach to the small intestine. Therefore, in terms of water supplement, sports drinks are not conducive to the absorption of water, unless athletes engaged in intense sports, such as marathon runners or people with severe diarrhea, the average person does not need to supplement electrolytes. Especially for people with poor renal function, high blood pressure and heart disease, due to excessive sodium in sports drinks, edema may be caused or excessive potassium cannot be discharged, thus raising blood pressure. In short, boiled water tastes healthy and has no heat burden. Drinking boiled water is the best. Drink more water, drink more water, but how much water is the standard. In fact, there are no strict standards, but there are some statements for reference. For example, if you see that your urine is as clear as boiled water, and the amount is large and smooth, it means that you have drunk enough. If the color is dark, you should drink more water. However, I would like to remind you that sometimes the urine is clear as water, which is not due to insufficient water, but may be due to renal failure, and it is impossible to excrete the waste in the body. So it's best to consult a doctor to find out if your kidneys are healthy. At the same time, if you exercise, you should also increase the amount of drinking water. You can refer to the following calculation method: water consumption = "urine volume" plus "non-sensory water loss" 1. Urination volume: the average person cc per minute, so the normal urine volume for 24 hours a day is 1400 ㏄. Second, the water loss without feeling is calculated as per kilogram 10 cc. For example, for a person of 70 kg, the water loss without feeling is 700 cc. Because of this, a 70 kg normal person should drink at least 2300 ○○C a day. As for patients with stones, gout, heart failure, renal failure, liver cirrhosis, ascites or uremia, the amount of drinking water should be adjusted according to the doctor's advice. Drinking water is especially important for the elderly. Because the water content in the body of the elderly is obviously reduced, and the perception of the elderly is relatively slow, there is little thirst, so it is often impossible to correctly reflect the lack of water in the body. When the water content in the body is insufficient and the water intake is too small, the cerebral blood flow is reduced, which aggravates the symptoms of hypertension, the cerebral oxygen and blood sugar are low, and the cerebrospinal fluid is too sticky, which affects the nerve conduction speed and the sharpness and sensitivity of brain activity, and people are prone to dullness. It is related to Alzheimer's disease, so we must pay attention to the intake of water. Water contributes to the digestion and absorption of food and the transport of nutrients in the body, and can dilute the waste in the body, such as uric acid, so as to facilitate renal excretion and prevent constipation. In order to avoid going to the toilet at night and affecting sleep, you can drink more water during the day.
