Our bodies can t do without water, so how much water should we drink every day?

You should drink about 800 ml of water a day, which can replenish the water that the body needs, but drinking more is good for the body.

It is necessary to drink at least eight glasses of water a day, which is 1200 ml, to meet the needs of the human body.

80% of the human body is made up of water, even if the metabolism in the body is inseparable from the participation of water, an adult drinks about eight to ten glasses of water a day, and children generally drink three to five glasses of water.

Generally, we would say that we should drink eight glasses of water a day, about 1800 to 2000ml, which is enough for our daily needs.

Drinking at least five glasses of water a day can maintain a normal life, theoretically 8 glasses, but not for everyone.

Medicine requires eight glasses of water a day, but this varies from person to person.

Generally speaking, drinking eight glasses of water a day in an ordinary glass can meet the body's needs.

The claim that we should drink 8 glasses of water a day is largely due to a report published in 1945 by the Food and Nutrition Committee of the National Academy of Sciences, according to which we need to replenish one milliliter of water for every calorie we eat. This means replenishing 2,500 ml of fluid per day, which is equivalent to 8 glasses of water.

A few years ago, Heinz Waltin, a kidney specialist at Dartmouth Medical School, decided to conduct a study to see if there was a scientific basis for the recommendation to drink eight glasses of water a day. After flipping through the articles of many of his peers, he concluded:

For healthy adults who live in temperate zones and exercise lightly, there are no scientific studies to support this 8-glass water theory.

In fact, following this recommendation, or taking more of it, "can even be harmful, because not only can it be dangerously low natremia, but it can also expose people to pollutants and make people feel guilty for not drinking as much water." He wrote in a review chapter of the American Journal of Physiology: Management, Integrative and Comparative Physiology.

Dr. Naohiko Imai, who works as an assistant professor in the Department of Nephrology and Hypertension at Santa Mary's Medical University Hospital in New York, said that in addition to the water you drink, the water contained in food and the water produced in your body are also ingested.

In this way, there is no need to drink 8 glasses of water in 1 day. He recommends drinking 1 1000 ml of water a day. Occasionally, for a few days, it doesn't matter if you only drink 500ml of water a day.

The kidneys are smart organs that automatically keep their bodies hydrated when they don't drink water. If you drink too much water, it will automatically excrete excess water. Those who eat well, even if they drink 6000 ml of water a day, the excess water will be excreted by the body.

Why do you need to drink water? How much water should we drink in a day?

A person can live for 3 weeks without food; Without water, it can survive for 3 days. For the human body, water is second only to air.

Water is the most abundant substance in the human body. 60% and 70% of an adult's body weight is water. The main component of blood is water, and our muscles, lungs, brain, and other tissues and organs also contain a lot of water.

Water is a good solvent for many minerals, vitamins, glucose, amino acids and other nutrients, and of course it is also good for dissolving metabolic waste products such as urea. Water transports nutrients into cells, transporting metabolic waste products from the body, ensuring that substances are exchanged between cells, interstitial fluids, and capillaries. This is important for the maintenance of cellular homeostasis.

Water is also the main component of the thermoregulatory system, the heat generated by energy metabolism in the body is transmitted to the surface through body fluids, and the excess heat is taken away by evaporation or perspiration to keep the body temperature constant.

In addition, water is also involved in the formation of various mucus, such as joint lubricants, saliva, gastrointestinal mucus secreted by the digestive tract, mucus in the respiratory airways, and mucus in the genitourinary tract, which play an important lubricating role in the human body. When walking or running, water tends to act as a "buffer" to maintain cell morphology, a function that plays an important role in protecting our brain and spinal cord.

It is advisable to drink water several times at different times of the day, and the principle is to drink a small amount of about 200 ml each time. During sleep, although we don't feel the body's activity, we also lose a lot of water. Even if you don't feel thirsty after waking up, your blood will become sticky due to lack of water.

When water intake exceeds the kidneys' ability to excrete (liter hours), it can cause excess water in the body or water intoxication, which can lead to hyponatremia. Water poisoning is rare in normal people, and those with conditions such as kidney and liver disease and congestive heart failure are prone to water poisoning in hot environments.

Generally speaking, the human body needs about 2000 ml of water every day, it should be better, usually pay attention to drinking more water, according to their own specific situation to observe and adjust is better, to avoid drinking less water for a long time, causing the body to lack of water, regularly go to the hospital for further examination and diagnosis, observe the specific manifestations for symptomatic adjustment, pay attention to strengthening nutrition, pay attention to eating more liquid diet.

The amount of water a person drinks every day depends on the amount of exercise and the structure of food. If you regularly eat vegetables, fruits, and drink porridge, you can reduce the amount of water you drink by supplementing more water in your diet. In addition, when you exercise a lot of work, or when the ambient temperature is high, there will be an increase in sweating, and you need to increase the amount of water you drink.

Under normal circumstances, the human body needs about 2500 ml of water per day, minus the amount of water replenished in food, which is the amount of water needed, generally 1000-1500 ml.

Drinking more water is good for the human body, and the average daily water requirement of adults is more than 2500ml, of which about 1500-2000ml** is consumed in direct drinking water, and the rest is ingested from food. The human body normally needs to replenish about 2000ml of water a day, and it needs to be replenished more in summer or during strenuous exercise, and at the same time, it is also necessary to pay attention to replenishing electrolytes and vitamins that are excreted from the body with sweat.

Many people have the misconception that drinking more water is better, drinking too much water will increase the burden on the kidneys and heart, will cause edema of the body, and even cause organ failure, so for ordinary people, the maximum amount of drinking water per day should not exceed 5000ml, unless it is in a lot of exercise, physical activity or hot days to drink more water does not matter, but also to promote excretion. When drinking water, try to drink more during the day and less at night, because drinking too much at night will also aggravate the disorder of kidney excretion and lead to edema, so choose the appropriate amount to drink according to the specific situation.

Drink too much, and don't drink too much.

Generally speaking, the amount of water lost by the human body every day through urine, sweat or evaporation is about 1800 2000 ml, so it has always been believed that about 2000 ml of water needs to be replenished every day. But this 2000ml of water is not necessarily obtained by drinking water, and the various foods we eat every day contain a lot of water, which should be counted together.

Therefore, after deducting the 1000 to 1200 ml of water intake from food in three meals, we only need to drink another 1500 ml of water every day, which is enough. The general rule is: no less than 500 ml a day, but no more than 3000 ml a day.

People who need to drink more water, such as gout and kidney stones, should follow their doctor's advice.

Adults who are engaged in light physical activity living in mild climates need to drink 1500-1700 ml of water per day.

When we lose more water when we are active, we should increase our water intake. For a short period of exercise, an additional 400 600 ml of fluid can be replenished to make up for the lost water; However, if you do strenuous exercise that lasts more than 1 hour, you need to drink more fluids. In addition, the hotter environment makes perspiration increase, and turning on air conditioning or heating indoors or on the plane can cause the evaporation and loss of water in **, and it is also necessary to increase the amount of water intake.

Drinking alcohol will speed up the metabolic response in the body, so that the amount of urine output increases, and there is no fixed amount of increased water intake that should be supplemented, as long as the water balance in the body is maintained.

The human body is made up of 75% water, so we have to drink water every day. Each person should drink about four catties of water a day, this amount can fully maintain the water balance in the human body, if you drink less water, it is not conducive to the healthy development of people.

Drink at least 1200ml of water to meet the body's needs, because the body's metabolism needs a lot of water, and the regeneration of cells in the body also needs waterIt will cause physical discomfort, and it will also make some diseases high, which is not good for physical health.

1. Drink at least six glasses of water a day

Healthy adults drink at least 6 glasses of water a day, about 1200ml is enough for the body, because healthy adults need to consume about 2500ml of water every day, they can take in water through three meals a day, and after removing those, they need to drink at least six glasses of water a day, about 1200ml to maintain the normal metabolism of the body. However, when the outside temperature is high and the personal physical exertion is large, it is necessary to increase the amount of water to drink.

2. Drink water in small sips and slow drinking, and divide it into multiple times

Adults should drink at least 1200ml a day to meet the needs of the body, and when drinking water, they must drink it many times, and they should take a small sip of slow drinking with a 200ml cup as an example, you can drink a glass or half a glass of water every hour, and drink a little more after going home at noon, and you can drink water on time after forming a habit to meet the needs of water for body work.

3. The amount of water to drink should be suitable for each person

Adults drink at least six glasses of water a day, which is a general statement, it is not suitable for everyone, and the specific amount of water to drink should be suitable for the person. For example, if the blood viscosity of people is relatively high, and the coronary blood supply is insufficient, such people should drink more water, only by drinking more water can the blood viscosity be reduced, and the occurrence of myocardial infarction can be avoided in order to maintain cardiovascular health. But when people have heart failure, they can't drink too much water, otherwise it will increase the burden on the heart, and it is easy to aggravate the condition, and then suffer from nephritis or kidney disease.

People can judge whether they should replenish water by the color of their urine in their daily life, normal urine is light yellow, if you find that the urine color becomes darker, you should drink more water for the body in time, if you find that the urine color is particularly light, it means that you drink too much water, you can reduce the amount of water you drink in moderation.

Generally, drinking water every day is enough for the body. It is best to drink from the beginning of the day, then every 2 to 3 hours, and do not wait until you are thirsty. Because for a healthier metabolism, you need so much water.

It is necessary to drink enough 800 ml of money every day to meet the body's needs, because a lot of water is needed to promote metabolism, help the body detoxify, clean up the garbage in the blood, and maintain health.

Drinking about 2500 ml of water every day is enough for the body, because the body consumes more water and needs to have a lot of water, so it is necessary to ensure that the body is fully hydrated every day.

Why is water so important for human health? How much water should I drink per day?

1.Water is an essential ingredient in the body, giving the body normal somatic effects and the transmission of all physiological needs.

2. Participate in metabolism and give structural substances that produce cells.

3. Maintain the normal functions of digestion, absorption, absorption and discharge.

4. The saturated solution that plays the role of key transport substances in the circulation.

5. Maintain human body temperature.

6. Maintain the balance of somatic cells inside and outside.

7. Adjust physiological functions: many metabolic reactions in the body need to be carried out in water; Therefore, if there is less water, many of the reactions will be disturbed and the normal functioning of the body will be impaired.

1.Drinking a glass of boiled water before going to bed can reduce the occurrence of symptoms, especially for good friends with bad hearts, and it can also be said to be a cup of life-saving water. Some people are very prone to heart attack or cardiovascular-related diseases when they wake up in the morning, which is caused by excessive blood viscosity in the body, which will lead to cardiovascular-related diseases.

2.Drink a glass of cold boiled water in the morning for beauty and skin care. Through a night's sleep, the waste retained in the body must have an external force to help discharge, in fact, there is no cold boiled water containing all substances is the most suitable, with the best practical effect.

3.Fat people drink some warm water half an hour after eating, and their physical and mental health is ****. Some people say that you can **** without drinking water, and that view is definitely incorrect and undesirable, so your sister must avoid it.

Many chemical changes in our body are carried out with water as the basic substance, and some useless substances formed in the basic metabolism must also be removed and relieved by water, as well as digestion and absorption, and immune molecules.

4.When you have a fever and a cold, you should drink more warm water than usual, which can promote perspiration and facilitate urination, so that the body's body temperature can be adjusted more quickly, and pathogenic bacteria in the body will be quickly excreted. When we have a fever and a cold, there will be some water evaporation such as sweating, inhalation and other increases, so that the metabolism will also accelerate.
