People can't do without water, which is the most basic common sense.
Water is an important part of the human body, accounting for about 50% to 70% of the body's weight, and every cell, tissue and organ in the human body needs water to maintain normal functioning.
When there is not enough water in the body to perform normal functions, dehydration occurs, which in turn affects the body's metabolic order, such as decreased urine, thirst, fatigue, listlessness, etc.
If it is not replenished in time, it will directly damage the function of the organ in severe cases.
Timely replenishment of water can not only quickly replenish the lost water, stabilize the electrolytes in the body, and promote the excretion of waste products in the body. Therefore, taking water is of great significance for the continuation of life.
But the problem is that ---- drink too much water, it will also be fatal.
Drinking water can also be poisoned? Woman drinking 3 liters of water in 2 hours is in danger of dying in the ICU
Recently, according to media reports: Ms. Liu from Zhengzhou, Henan Province, because she wanted to have a colonoscopy, she needed to drink more water and laxative drugs to help empty the stool in the intestine.

So the family rushed to the hospital for rescue, and finally diagnosed with water poisoning, they immediately sent Ms. Liu to the ICU for rescue, and finally got out of danger of life.
Does drinking too much water affect the body?
You know, after the human body sweats a lot, it will lose part of the water and electrolytes at the same time, at this time, if you drink fresh water quickly and in large quantities, you will only replenish water without supplementing electrolytes.
Once the electrolytes in the blood are diluted, it will cause the concentration of electrolytes in the blood to decrease, the concentration of electrolytes in the cells will increase, and the water will easily enter the cells from the blood, causing cellular edema, thus causing "water intoxication", also known as dilutive hyponatremia.
How much water does the human body need in a day?
The body loses water every day through breathing, sweat, urine, and excretion. In order to ensure the normal operation of the body, it is necessary to replenish water by drinking water or watery foods.
According to the body's daily need for water and the water lost by active metabolism, a normal adult should be replenished with appropriate water every day, generally about 15.5 cups (3.7 liters) of water per day for men, and about 11.5 cups (2.7 liters) of water per day for women.
Of course, this moisture covers liquids from other beverages as well as food, and about 20% of the liquids that the human body consumes every day usually comes from food, and the rest comes from water and beverages.
For some special cases, it is necessary to decide the amount of water to drink according to the situation at that time.
First, exercise
Due to physical activity during exercise, the metabolism is vigorous and the water loss is fast. At this time, it is necessary to drink more water to make up for the loss of water. Drinking water before, during, and after exercise is especially important.
Athletes may sometimes drink too much water to prevent dehydration during prolonged or strenuous exercise.
Second, the heat
Hot or humid weather will make the body sweat and accelerate the loss of water, then it is necessary to replenish water in time.
Third, get sick
If the body has fever, vomiting, or diarrhea, due to the loss of water in the body, additional hydration is required, such as oral rehydration solution under the guidance of a doctor, or intravenous fluid.
In addition, if there are urinary system problems, such as urinary tract stones or bladder infections, fluid intake needs to be increased.
How do I know if I've drunk enough water?
If the body has the following conditions, it means that the intake of water in the body is sufficient, that is, it is rare to feel thirsty, and the urine is colorless or yellowish when it proves that the water in the body is maintained in an adequate state.
To prevent dehydration of the body and ensure that the body is getting enough water, it is recommended to use water as the main beverage.
Of course, for some special cases, you need to pay attention to the amount of water you drink.
If it is a person with poor kidney function, it is recommended not to drink too much water, because the kidneys can not remove excess water, if you drink too much water at once, it will lead to electrolyte imbalance, which may be life-threatening.
For children under 6 months of age, feeding is not recommended for any liquid other than breast milk or formula, including water, juice, glucose water, etc., unless certain medical indications are available.
Because your baby's stomach is small, extra water can also affect the amount of milk you drink normally, which can lead to malnutrition.
