Is drinking too much water bad for your health? Why drinking too much water is bad for your health

First of all, from the perspective of brain function, after drinking a lot of water, the human body is more likely to feel tired, appetite is greatly reduced, and the brain feels groggy.

Generally speaking, drinking too much water may dilute the blood, the oxygen exchange of cells in the whole body will be affected to a certain extent, and brain cells will become sluggish once they lack oxygen, because excessive water intake will increase the burden on the heart and kidneys, so people with heart disease, high blood pressure, kidney disease and level can not drink a lot at a time, because labor or labor sweating a lot, it is not appropriate to drink too much at one time.

First of all, water poisoning refers to drinking too much water for a long time or drinking a large amount of water in a short period of time, the body must use urine and sweat to discharge some excess water, but these water can not be discharged with water, the electrolyte in the human body is diluted, the salt in the blood will be less and less, and the ability to accumulate water will also be reduced, and some water will be quickly absorbed into the tissue cells, making the cells edema and dizziness.

Our dietary guidelines recommend drinking 1,700 ml of water per day for adult men and 1,500 ml per day for adult women. Of course, this amount is not fixed and can be adjusted according to your own situation. For example, if you exercise more and sweat more, you can drink more; If it is in the hot summer, it needs to be appropriately increased according to the intensity of labor and the degree of sweating.

In fact, the fundamental purpose of drinking water is to meet the body's demand for water. To put it bluntly, water is mainly a porter of nutrients and metabolic wastes in the body, it is just a carrier, no matter what water you drink, it is impossible to treat it as a nutrition**, and it is impossible to have any miraculous effects. Therefore, as long as the water meets the national standards, it can be drunk safely and securely, and there is no question of "which water is healthier", and everyone does not have to worry about what water to drink.

Excessive drinking of water must be harmful to the body, and drinking water in moderation is beneficial to the health of the human body, which can ensure the water required by the human body and maintain the normal life activities of the body. However, when drinking too much water, it will lead to water poisoning, due to the permeability of cells, excessive intake of water will make the concentration of extracellular fluid lower than the concentration of intracellular fluid, resulting in intracellular edema, which will increase the burden on important organs such as the heart and kidneys, and will also appear edema of the body, especially in patients who develop to the later stage, there will be severe pitting edema, and in addition, it will also cause hypervolaemic hyponatremia due to the penetration of some ions of intracellular fluid into extracellular fluid. These are very serious, so we must pay attention to the right amount of water and do not drink too much water or too fast, so as not to lose more than we gain.

Drinking too much water will increase urination, which is generally not harmful, but if you drink too much water in some cases, it is harmful.

In mild climates, it is generally recommended to drink 7 8 glasses (1500 to 1700 ml) of water a day to avoid feeling thirsty before drinking. Because some substances, such as salt, are excreted in urine or sweating, drinking too much water can lead to excessive salt loss and deficiency. For people who exercise a lot, have high labor intensity, or are exposed to special environments such as high temperature and dryness, it is necessary to consider supplementing a certain amount of minerals at the same time.

I drank at least 10 bottles of water every day, that is, 10 pounds of water, and after drinking it for half a month, I suddenly fainted and was admitted to the ICU. Mr. Wang's situation is colloquially referred to as "water poisoning". "Water poisoning" does not refer to poisoning caused by water deterioration or the presence of toxic substances in the water, but rather hyponatremia.

Yes, there is a certain range of water intake for a normal person, and the amount of water they drink has a lot to do with how much they urinate, how much they sweat, and how much water they lose in the respiratory tract. If you have a lot of urine and sweat, you need to take too much water to replenish the body's water loss. If you take too much water, the amount of urine is not much, or the body does not sweat, it may cause a burden on the kidneys, resulting in kidney damage and edema.

If the kidneys are functioning within the normal range, they can excrete too much water from the body, and a large amount of water ingested in a short period of time may cause water toxicity. Water poisoning is the rapid decrease of osmotic pressure in the body's plasma after the body ingests water, and the intracellular osmotic pressure decreases more slowly, and the water enters the cells through the osmotic pressure difference, causing intracellular swelling, and the symptoms of nausea, vomiting, and dizziness appear, which is the cause of water poisoning. When drinking water, you should stop in moderation, take thirst as the standard, do not drink water if you are not thirsty, and do not drink a lot of water excessively.

Drinking too much water is harmful to the body and can lead to water poisoning. Water poisoning can also be called hypervolaemic hyponatremia, which is characterized by: 1. High volume, that is, the volume of water is too high, and the water is drunk too much.

2. The blood sodium is reduced, the serum sodium concentration is 130mmol L, the plasma osmolality is 280mmol L, and the patient has water and sodium retention, which significantly increases the amount of body fluid, so it is called water poisoning. At this time, the amount of extracellular fluid increases, hemodilution decreases, serum sodium is further reduced, extracellular fluid is hypotonic, and water is transferred from the outside to the cell, resulting in intracellular edema. Therefore, the water retained in the intercellular fluid in the early stage is often not sufficient to produce pitting edema, and pitting edema can occur in advanced or severe patients, which is one of the characteristics of water intoxication.

Drinking too much water has several hazards:

1.Drinking too much water will reduce the permeability of the smile, causing water to penetrate into the cells, causing the cells to swell and the body to become water poisoned.

2.When brain cells are edema, the pressure in the skull increases, causing dizziness, vomiting, and fatigue. At the same time, breathing and heart rate can also decrease, and even cause coma and become life-threatening.

3.In summer, after sweating a lot, it is necessary not only to replenish water, but also to add an appropriate amount of table salt to the water to replenish salt. Avoid water poisoning.

4.People with weak heart and kidney function should also not drink a lot of water, so as not to cause a burden on the heart and kidneys.

5.Avoid drinking boiling water, i.e. water that has been boiled repeatedly. Generally, the water in the water dispenser will automatically reheat and shudder at a certain temperature. This is not healthy for the human body.

6.If you don't have enough to eat an eggplant, you should drink a liter of water a day. i.e. 5 bottles of 500 ml of mineral water. This can effectively promote the body's metabolism.

In general, healthy adults are enough to supplement 1000-2000ml of water per day under normal activities. How much do you mean by overdose? If the daily excess is not too much, the human body has an automatic water regulation mechanism (mainly the kidneys), and the excess is discharged, which will not cause much impact, and at most let you urinate more often; When you drink too much water for a long time, it will increase the burden on your kidneys, making it often overwork, and it will definitely get sick.

If you have high blood pressure and chronic renal insufficiency, excessive water consumption will also cause harm and even life-threatening.

Therefore, it is correct to drink water appropriately according to your different health conditions.

You can't overdo it, you have to have a degree in everything. Drinking too much water is easy to get water poisoning.

Some people drink a lot of water in one sip when they are thirsty in the summer, or after exercise or labor, and feel very "happy" and "thirst-quenching" at that time, but they do not know that this is harmful to the body. Because people sweat a lot after labor, exercise, or extreme heat, which not only loses water, but also loses a lot of salt. The more you sweat, the more water and salt your body loses.

It is calculated that there are grams of salt in 1 liter of sweat, so sweat is salty. If you sweat 5 liters in half a day, you will lose grams of salt. If you drink a large amount of white water at a time without replenishing salt, the water is absorbed by the stomach and intestines, and then excreted from the body through sweating, and some salt is lost with sweating, as a result, the salt in the blood becomes too little, and the water absorption ability is reduced, and some water will be quickly absorbed into the tissue cells, making the cells edema, causing "water poisoning".

People will feel dizzy, dizzy, thirsty, and in severe cases, they will suddenly faint, which is called "dehydration and hyponatremia" in medicine.

When a person feels thirsty after sweating profusely, it is not entirely due to a lack of water in the body, but a feeling caused by a small amount of saliva, thick saliva, sticky mouth, and dry throat. At this time, the correct way to drink water is: first rinse your mouth with water, moisten your mouth and throat, then drink a small amount of water, stop for a while, and then drink some, so that you can drink it several times, and it will not damage your health due to "water poisoning".

Drinking too much water is also harmful Recently, a British man suffered from a rare water poisoning and collapsed due to drinking too much water due to thirst. Doctors warn that even drinking 5 liters of water in an hour is enough to kill. Every year, cases of problems caused by excessive drinking water are detected in Hong Kong, and more than 100,000 patients with drinking addiction are counted in the United States.

In Hong Kong, a 16-year-old girl was found to be greedy and drank 20 liters of distilled water a day, and finally drank too much water and was "poisoned" and was hospitalized. "Water intoxication" refers to drinking too much water for a long time or drinking a large amount of water in a short period of time, the body must use urine and sweat to excrete excess water, but with the discharge of water, the electrolytes in the human body mainly sodium will be diluted, the salt in the blood will be less and less, the ability to absorb water will be reduced, and some water will be quickly absorbed into the tissue cells, making the cells edema. Symptoms such as dizziness, weakness, and rapid heartbeat begin to occur, and in severe cases, convulsions, impaired consciousness, and coma may occur.

Therefore, it is very dangerous for some girls to rely on drinking too much water. Experts explained that this case of binge drinking is very rare, and the normal kidneys can only excrete a maximum of 10 to 20 liters of urine per day. Since sodium is an important electrolyte for maintaining the function of the body's cells, it affects various bodily functions.

Generally, 8 glasses of water per person per day is more appropriate, and it should be stopped if you notice dizziness, fatigue or tiredness. According to reports, drinking water health ** has been all the rage in recent years, and advocates believe that drinking more water can make ** more shiny and elastic, and drinking a lot of water can clean up the metabolites in the body in time to prevent stone disease. However, from the perspective of brain function, after drinking a lot of water, the human body is prone to feel tired, appetite is greatly reduced, and the head feels groggy.

Doctors point out that this is because drinking too much water dilutes the blood, and the oxygen exchange of cells throughout the body will be affected, and once brain cells are starved of oxygen, people will become sluggish. In addition, some people are "addicted" to drinking water, "addicted" to tea, and even worse, some people "quantify" drinking water, and the daily water intake must reach a certain "index", such as drinking several large glasses of water and drinking several pots of tea a day, so drinking water will undoubtedly have a negative impact on the body. Therefore, whether you drink tea or boiled water, there should be a limit.

Experts say that the amount of water you drink per person should depend on your personal condition, and it is best to drink a small amount and drink more. From the perspective of dietary hygiene, it is better to drink cold boiled water, salt boiled water, tea or fresh mineral water, but it should be noted that drinking too much water at one time and drinking too fast is not good for the body, especially for the elderly. Because too much water intake will increase the burden on the heart and kidneys, people with heart disease, high blood pressure, kidney disease and edema should not drink a lot at one time, and they should not drink too much at one time after sweating a lot due to labor or exercise.

Pregnant women should also drink moderate water, pregnant women must drink enough water every day to meet the consumption in the body, but drinking too much water will cause or aggravate edema. Generally, pregnant women can drink 1 to kilogram of water per day, but not more than 2 kilograms, and less than 1 kilogram in the third trimester of pregnancy.

Did you know that drinking too much water at one time can cause water poisoning?

After drinking a lot of water, the human body is prone to tiredness, greatly reduced appetite, and makes people feel groggy. This is because drinking too much water dilutes the blood, and the whole body cell gas exchange is affected. As soon as brain cells are starved of oxygen, the person becomes sluggish.

According to experts, people with normal kidney function can only excrete up to 10 to 20 liters of urine per day. If you drink too much water, the kidneys will not have time to excrete the excess water, and the accumulated water in the body will dilute the blood and cause low blood sodium. Since sodium is an important electrolyte for maintaining the osmotic pressure of human cells, low blood sodium can affect various functions of the body.

How much water is best for the average person to drink every day? Experts say that the amount of water per person should be based on individual circumstances, and it is generally advisable to rise. From a hygienic point of view, it is better to drink cold water, tea or mineral water.

However, it should be noted that drinking too much water at one time or drinking too quickly is not good for the body, and it is not advisable to drink too much water at one time after sweating a lot due to labor or exercise.
