First, it can be calculated by weight.
According to the research of the International Institute of Medicine in Los Angeles, the standard for adults to drink water every day is to supplement 40 ml of water per kilogram of body weight every day.
Second, it is estimated according to the discharge.
The average adult's daily total exhaust volume is about 2500 ml. According to the principle of intake and elimination balance, the daily water demand of adults is about 2500 ml.
Third, it is estimated according to the American dietary nutrition supply standard.
Adults need 1 ml of water for every calorie consumed, while infants need 1 .5 ml. Adults need to consume about 2000 kilocalories a day on average, so according to this calculation method, the daily water demand of adults is also between 2000 and 2500 ml.
No matter which calculation method, everyone should consume no less than 2000 ml of water every day and directly drink no less than 1500 ml of water. Don't wait until you are thirsty to replenish water.
At the same time, we should also choose natural, healthy and weakly alkaline drinking water containing a variety of natural mineral elements.
What is the standard amount of water a person drinks a day?
1, depending on the color of urine, how much to drink.
Many people's understanding of drinking water is limited to quenching thirst. In fact, drinking water is also a science, and drinking water correctly is very important for health.
Water is the source of life, and all human life activities are inseparable from water.
For the human body, water is not only the carrier of "transporting" various nutrients in the body, but also directly participates in the metabolism of the human body. Therefore, it is very important to ensure adequate water intake for the normal operation of human physiological functions.
How much water to drink varies from person to person.
Generally speaking, the amount of water people drink every day should at least be in balance with the amount of water they consume in their bodies.
The amount of urine excreted by human body in one day is about 1 1,500ml, and the total water consumption is about 2,500ml, while the water that human body can metabolize and replenish from food and body is only about 1 1,000ml, so normal people need to drink at least 1 1,500ml of water every day, about 8,000ml.
Usually, how much water each person needs to drink varies according to the activity, environment and even the weather.
Drinking more water for normal people will not have much impact on the body, but it may lead to increased urination and inconvenient life.
However, for some special people, we must pay special attention to the amount of drinking water. For example, patients with edema, heart failure and renal failure should not drink too much water, because drinking too much water will increase the burden on the heart and kidneys and easily lead to aggravation of the disease.
For patients with heatstroke, cystitis, constipation, dry skin and other diseases, drinking plenty of water can play a certain role in relieving the disease. In addition, people should drink more water when they have a cold and fever, because rising body temperature will cause water loss. Drinking more water can promote body heat dissipation and help patients recover. Pregnant women and people who exercise a lot consume a lot of water and should drink more water.
