How much water is best a person drinks per day?

People drink at least 1500cc of water a day, and how much to drink depends on their weight, and every 1 kilogram of body weight can correspond to 30 ml of water.

Drinking water: Drinking water is the way the living body ingests water through the mouth, and the body ingests about 2 liters of fluid through the mouth every day. Water is mainly absorbed in the stomach, and after entering the human body, water is mainly used to replenish intracellular fluid and extracellular fluid, and participates in various physiological activities of the human body.

How to tell if there is a lack of water:

If you don't know if you're drinking too much or too little water, here's a tip to tell by the color of your urine. Generally speaking, a person's urine is pale yellow, if the color is too light, it may be that you have drunk too much water, if it is too dark, it means that you need to replenish more water.

Drinking water scientifically at least 1500 ml per day Drinking water is too important for both healthy people and patients, not only to promote the excretion of toxic metabolites, but also to reduce local symptoms of the upper respiratory tract, and adequate rehydration will make people feel better physically and mentally. In winter, drinking plenty of water can be a great way to relieve symptoms such as a sore throat. Now in winter, most office workers have to undergo a double "baking test", there is heating at home, and there is ** air conditioning in the unit, in this dry and stuffy environment, if you drink less water or just drink water normally, it may cause hidden dehydration of the human body.

Hidden dehydration can make the body's resistance decrease and make it listless. In addition, the local indoor air is not circulated in winter, and the concentration of the virus in the unit volume will increase many times. In winter, each person should drink at least 1500 ml of water a day, about 6-8 cups, and the specific amount depends on their own situation.

Drink 200 ml at a time Maybe it's because life is too busy, work is too intense, or maybe it's because the problem of drinking water is too small for people to pay attention to. In real life, many people drink water when they are thirsty, or just drink a little bit each time like a "dragonfly". Actually, neither of these practices is correct.

In fact, 75% of the body is water, and you will only feel thirsty when you lose 2% of your body water, which means that when you feel thirsty, your body is already in a state of chronic water shortage. Therefore, drink water regularly. Not only that, but drinking water regularly does not mean that you only need to drink a little at a time, there is also a question of quantity.

Drinking too much or too little water every time is not good. Only 70% of the water is absorbed by the human body, and drinking too much at one time will increase the burden on the stomach and intestines. The correct way should be to drink 200-250 ml each time, so that the body can really absorb and utilize.

The Dietary Guidelines for Chinese Residents point out that healthy adults need about 2500 ml of water per day, considering the water in food, the guidelines recommend that in mild climates, adults with light physical activity should drink at least 1200 ml of water per day, taking a 200 ml cup as an example, then it is 6 cups of water. If you are physically active, or if the ambient temperature is high, then drink plenty of fluids.

Under normal circumstances, a person should drink 3,000 ml to 8,000 ml of plain water! This is more scientific!

If you do not exercise much, you should drink 15 millilitres of water for every half kilogram of body weight (i.e. a person weighing 80 kilograms should drink 2,400 millilitres or 2.4 litres of water per day); If you are an athlete, you should drink 20 milliliters of water per half kilogram of body weight (3,200 milliliters or 3.2 liters of water per day for a person who also weighs 80 kilograms).

Drinking water is the same as taking in calories, you should replenish as much as you need. There is no scientific evidence that you can detox more by drinking more water. On the contrary, if a person drinks too much water, it is very easy to lose electrolyte balance (a large loss of sodium and potassium ions) and water-soluble vitamins (such as B and C) are more likely to be lost.

How much water should a normal person drink per day? Studies have found that, in general, the amount of water that the human body loses every day from urine, sweat or evaporation is about 1800-2000cc, so it has been said for many years that healthy adults need to replenish about 2000cc of water every day. However, the 2000cc of water is not necessarily obtained by drinking water, but the water in the food should be taken into account, which is the correct health care method.

In fact, the various foods we eat every day contain a lot of water. For example, most vegetables and fruits are more than 90% water, and eggs and fish also contain about 75% water. As a rough estimate, we can get at least 300-400cc of water from food or soup in one meal.

Therefore, after deducting the 1000-1200cc of water intake from food in three meals, we only need to drink another 1000-1200cc of boiled water every day, an average of 2 cups in the morning and 2 cups in the afternoon, which is enough!

However, we should also know that the amount of water required must depend on each person's environment (temperature, humidity), physical activity, physical health and food intake, etc., and there is no fixed standard value. Experts believe that the general rule of drinking water is: no less than 500cc a day, but no more than 3000cc a day.

8:30: In the early morning, the process from getting up to the office is always very tight, and the mood is also relatively tense, and the body will be dehydrated, so when you get to the office, give yourself a glass of at least 250ml of water!

To remove the waste released by the human organs, it is necessary to consume litres of water every day. In the hot summer, if exposed to more than 30 days of sunlight, the human body has consumed 1000 ml of water by sweating alone, and the daily urine output per person is about 2000 ml. As a result, they don't function properly, and people don't bother to move.
