Will drinking more than the normal amount of water per day be detrimental to your health?

In recent years, people pay more and more attention to the message of health, from the thermos with goji berries to reduce the number of late nights, increase the amount of exercise, forcing themselves to drink eight glasses of water a day. But there is no specific way or quantity limit for each person's health, "the right amount" is the most difficult to grasp. Take drinking water for example. If you drink the wrong amount, it won't protect your health. It can also be harmful to your body.

Do you think drinking water means staying healthy? Expert: Drinking more than this amount per day could be toxic!

Drinking more than 4 liters of water a day may be toxic!

Bruce Gordon, a WHO expert, recently said that drinking more than 4 liters of water a day is not only good for the body, but can also lead to poisoning, resulting in brain damage and even death.What is the concept of 4 liters?4 liters is equal to 4,000 ml, no more than 500 ml of mineral water and 8 bottles. For many people who remember to drink 8 glasses of water a day, it is easy to get confused here. Remember 8 bottles not 8 glasses!

First, let's talk about the correct interpretation of 8 glasses of water a day:

We know that water is the source of life. It's not a fish, but we can't live without boiling water. We adults need about 3,000 to 4,000 milliliters of water for our daily physical activity. Note that this is the total amount! This includes eating fruits, meals, porridge and so on. If you remove these, according to the dietary guidelines of the Chinese Nutrition Society, men are recommended to drink more than 1700 ml of water per day, and women are recommended to drink more than 1500 ml of water per day. That's almost 8 cups in this case. That's about 200 to 300 milliliters, the size of an average glass.

Secondly, 8 glasses of water is not specific!

Just now, in order to maintain the normal functioning of the body, to ensure that the body's need for water and to eliminate the intake of water such as dietary beverages, it is important to get into the habit of drinking an additional 8 glasses of water a day. However, this is not specific. For example, if you drink a lot of porridge today and eat a lot of watermelon and other fruits today, you don't need to drink all 8 glasses. In addition, hot weather and sweaty sports require more than 8 glasses of water. In short, there is no need to forcefully drink water without feeling thirsty. If you do not want to drink as if you were completing the task, it is likely that the WHO expert at the beginning of the article will be concerned about poisoning, because the total intake for the day exceeds 4 liters!

Finally, is drinking water really toxic?

It really can be! We know that the water we drink in excess enters the bloodstream through the gastrointestinal tract and then flows through the kidneys to be metabolized and the kidneys excrete excess water from the body (urine). The kidneys regulate our body's water balance to some extent and are also responsible for our body's electrolyte balance, which is sodium. When you drink too much water, the burden on the kidneys increases and a large amount of water accumulates in the kidneys, which the kidneys are unable to excrete in time. The concentration of sodium ions in the blood will be over-diluted, resulting in low blood sodium, which affects the brain! The brain is very sensitive to this. Too little water in the brain cells, swelling of brain cells, increased intracranial pressure, causing headaches, vomiting, bradycardia, hypothermia, etc., and even life-threatening.

Also, parents with babies whose kidneys are underdeveloped should be reminded not to feed water too often. Water intoxication occurs in infants every summer, and it's common in hospital outpatient clinics.

The kidneys, as an important organ of the human body, can remove metabolites and some wastes and poisons from the body. Therefore, to a certain extent, the kidneys have some detoxification function. Many people may hear the argument that drinking too much water in their life is good for their health. So, is it really good to drink too much water? Will it burden the kidneys?

What are the harmful effects of drinking too much water on your body? Take a look at this article and you'll know

Professor Zhang Bin, a specialist in urology and men's specialties at the Third Affiliated Hospital of Sun Yat-sen University's Senior Professors' Association, explains that there is a limit to how much water the kidneys can regulate. Because the body's kidneys can not infinitely regulate the amount of water, if people drink a lot of water for a long time, once more than the capacity of their own kidneys, at this time it is very likely that water retention, thus destroying the homeostasis of the body's internal environment, causing the body organs of the corresponding problems.

As we all know, the body's kidneys have the important function of regulating the body's water. If you drink more water every day, you will urinate more and the color of your urine will be clearer accordingly. On the contrary, if you drink less water every day, the color of your urine may deepen. It can be seen that water only serves as a solvent in the human metabolic process, from low to high concentrations. In this process, water does not cause any major impact on the body's kidney cells.

It's worth noting that if you eat a lot of it at once or for a short period of time, it can also lead to water intoxication. "Water intoxication" occurs because the human kidneys have a continuous maximum diuretic rate of 16 milliliters per minute. Once the rate of water intake exceeds this, the excess water causes cellular swelling dehydration and hyponatremia. This usually leads to symptoms such as dizziness, vomiting, fatigue, rapid heartbeat, and in severe cases even cramps, coma and even life-threatening.

In fact, if you drink more water, the organ most affected by the body is not the kidneys, but the body's cardiopulmonary function. Prof. Zhang Bin pointed out that this is because when water enters the body, it first passes through the blood vessels, thus increasing the water content of the blood in the body. If you don't pay more attention at this time, it will eventually lead to the occurrence of high blood pressure, and in the long run, it may eventually lead to the occurrence of heart failure.

In addition, if people choose to drink water all at once or for a short period of time, it may lead to water intoxication. When water intoxication occurs in our lives, it usually leads to dizziness, vomiting, and rapid heartbeat. For some patients with serious conditions, symptoms such as cramps and coma may also occur, even directly endangering the patient's life.

From this point of view, although drinking more water is good for the human body, you should also pay attention to the amount of water you drink. Drinking too much water can adversely affect the body and lead to various harmful diseases, so people should be careful to avoid this situation.
