How much water to drink a day is normal, and how to drink water is healthy.

How much water to drink and how to drink water in a healthy drinking day Generally speaking, the water lost by urine, sweat or skin evaporation every day is about 1800-2000ml, so people always think that it is necessary to supplement about 2000ml of water every day. But this 2000 ml of water is not necessarily obtained by drinking water. All kinds of foods we eat every day contain a lot of water and should be counted together. Therefore, after deducting1000 ――1200ml of water for three meals, we only need to drink 1500ml of water every day, which is enough. The general principle is: not less than 500 ml, but not more than 3000 ml per day. People who need to drink more water, such as patients with gout and kidney calculi, should follow the doctor's advice. Make a schedule of drinking 8 glasses of water every day. It sounds simple, but it's hard to stick to it. Professor Hong Zhaoguang, a famous health educator in China, recommended a "drinking schedule" to help you reach the "drinking index" easily. After a night's sleep at 6: 30, my body began to lack water. Drinking 250 ml of water before getting up helps to detoxify the kidneys and liver. At 8: 30 in the morning, from getting up to the office, the body will be dehydrated invisibly, so when you get to the office, give yourself a cup of at least 250 ml of water first. 1 1: 00 After working in the office for a period of time, give yourself the third glass of water in a day to replenish the lost water, which will help to relax the tense working mood. 12: 50 Half an hour after lunch, drinking some water can strengthen the digestive function of the body. /kloc-drink a cup of healthy mineral water to refresh yourself at 0/5: 00. /kloc-before you leave the office at 0/7: 30, drink another glass of water to increase your satiety, so you won't overeat at dinner. 1 Drink another glass of water half an hour before going to bed at 22: 00, but don't drink too much at once, so as not to go to the toilet at night and affect the quality of sleep. Master the five principles of drinking water. So, what water should we drink? Someone once put forward the idea of "three glasses of water a day for health", that is, a cup of honey water in the morning, a cup of light tea after lunch break and a cup of boiled water before going to bed. For the elderly and people who are often constipated, drinking a cup of honey water on an empty stomach in the morning can promote defecation; If you still feel sleepy after lunch break, drinking a cup of light tea can refresh you; Drinking a small amount of boiled water before going to bed can replenish the water lost by sweating during sleep. First of all, truly effective drinking water can make the body really absorb effectively. 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), instead of just drinking two, so that the body can really absorb it. Of course, the so-called disposable drinking water does not have to be drunk at one go. If you just take a sip or two to quench your thirst, it won't help your health at all. Secondly, what kind of water should I drink? Drink good water. Try to avoid drinking distilled water often (generally distilled water is too acidic, which is easy to cause harm to the body, especially to people with weak kidneys), and you can choose high-quality mineral water. If possible, drinking alkaline water is most beneficial to the human body; Otherwise, there is no need to cook after filtering with a household water filter. In daily life, drinking fountains have become quite popular. At the same time, some ailments caused by improper use of drinking fountains are also emerging day by day, so we must be alert to the five misunderstandings of drinking fountains. Drink warm 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. Third, how to drink water? Drink water on an empty stomach, of course, at any time. Drinking when you are thirsty can only quench your thirst, but it won'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. Fourth, it can be published and received. Working people often neglect drinking water because of their work. Here, remind 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. Five, the best drinking opportunities four times a day. Water is one of the essential substances to maintain normal metabolic activities and physiological functions of human body. People constantly evaporate water from the lungs and skin and excrete water from the kidneys and feces every day. The inevitable water loss of human body every day is about 65,438+500ml. The summer climate is sultry, and when going out for activities and outdoor work, you often sweat more and lose more water in your body. Experts remind that you must not wait until your mouth is dry before drinking water, especially middle-aged and elderly people should develop the habit of taking the initiative to drink water, that is, drinking water regularly when your mouth is not thirsty. This is because middle-aged and elderly people are thirsty because their reaction to water loss is reduced. When the body sends out a "signal" of thirst, it is already in a state of severe water shortage. Water loss is the main cause of premature aging. When the human body is short of water, the whole body blood volume will drop, the heart perfusion pressure will drop, and myocardial ischemia will easily cause myocardial damage. In addition, when the body is short of water, sweat and urine will be relatively reduced, which will affect the excretion of metabolites in the body and make harmful substances accumulate in the body, causing chronic poisoning in the human body. Therefore, water intake should be timely and appropriate. Experts remind that under normal circumstances, it is better to drink a small amount of water many times. Drinking a lot of water at a time will do a lot of harm to the human body. In severe cases, it will lead to imbalance of water and electrolyte in the body and even water poisoning. Therefore, we must develop the good habit of taking the initiative to drink water at ordinary times. We should drink 1~2 cups of boiled water at the four "best drinking times" after getting up every morning, around 10, at 3-4 pm and before going to bed at night, and pay attention to replenish water in time after sweating too much, exercising or taking a bath. In addition, eating more fruits and vegetables is also an effective way to replenish water, which not only supplements water, but also provides necessary minerals and other nutrients. Drink water at regular intervals, and don't think of drinking water only when you are thirsty. Drink warm water with salt instead of ice water. Drink more boiled water instead of raw water. Drink fresh boiled water, not water that has been left for too long.
