Is it OK to drink too much water? What are the dangers of drinking too much water? What happens if y

There is not much benefit, if you drink too much, you will not absorb it, it is useless. The average daily water consumption of a normal person is milliliters, and the oxidation of substances in the body can produce milliliters of water, so milliliters of water should be replenished every day, including the water content in the diet. In summer, you need to replenish about milliliters of water every day to meet the needs of the human body.

Fat people like you sweat easily and are more prone to dehydration. Therefore, salt should be supplemented for heavy sweating. Because sweating loses a lot of water at the same time, it also loses more salt, and the osmotic pressure in the body will be out of balance, and the water drunk at this time cannot be stored in the cells, and it will be excreted from the body with sweating, and sweating will bring out salt, which will form a vicious circle of more and more thirst the more you drink.

In severe cases, it can cause muscle weakness, pain, and even convulsions. Therefore, in the hot summer, especially after sweating a lot, you should drink some light salt water. The composition of the human body 60 70 is water, if a person does not drink enough water, he will cause damage to all aspects of his physiology, this damage is often not easy to detect for a while, and when he is discovered, it has formed a serious injury, and a disease has occurred.

In fact, people are often in a state of dehydration, but they don't even notice it. Middle-aged obesity is the main culprit of many diseases, and it is a necessary prerequisite for various diseases. International expert studies on obesity** have concluded that:

Drinking water in moderation is key. They point out that if you don't drink enough water, many people will gain weight and lose muscle, because there is not enough water in the body, and the body cannot metabolize fat.

Drinking water is something you don't need to pay attention to.

<>1. There is a certain range of water intake for normal people, and the amount of water consumed has a lot to do with how much urine and sweating, and how much water is lost in the respiratory tract. If you have a lot of urine and sweat, you need to take too much water to make up for the loss of water in your body. If you take too much water, the amount of urine is not high, or the body does not sweat, it may cause a burden on the kidneys, resulting in kidney damage and edema.

2. If the kidney function is within the normal range, the body can take in too much water and excrete it from the body, and a large amount of water intake in a short period of time may cause water poisoning. Water poisoning is the reason for the occurrence of water poisoning after the body ingests water to pure content, the osmotic pressure in the plasma of the body decreases rapidly, and the intracellular osmotic pressure decreases slowly, and the water enters the cells through the osmotic pressure difference, causing intracellular swelling, nausea, vomiting, and dizziness, 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.

3. Drinking more water can promote metabolism, make all parts of the body more hydrated, prevent constipation, and prevent waste accumulation in the body. Drinking more water can use the normal operation of body functions, reduce wrinkles, make ** moisturizing, shiny, and can also make the secretion of body fluids normal, and there will be no dry mouth, dry eyes and other phenomena. Drinking more water has greater benefits for urological diseases and can also reduce the risk of diseases such as stones.

However, excessive drinking of water will cause blood dilution, and some people will also have weakness, dizziness, rapid heartbeat, and in severe cases, water poisoning. In addition, drinking more water will increase the burden on the kidneys and heart, which in turn will cause edema and have an adverse effect on the body.

When the total amount of water ingested by the human body greatly exceeds the amount of water discharged, will it be "poisoned"?

1. Drinking too much water will increase the burden on the kidneys. We all know that we detoxify through urine, the main component of urine is water, and all urine is filtered by the kidneys, therefore, if you drink too much water, it means that the kidneys filter more, which will increase the burden on the kidneys, we all have this experience, when you are very thirsty, pick up a bottle of water and drink it in one breath, as a result, it is to quench your thirst, but you will go to the bathroom to urinate within ten minutes, this way of drinking water is not correct. Therefore, drinking water should also master a certain amount, and you can't drink it too quickly, you should drink it slowly and sip like tea, so that it can really replenish the body.

2. Drinking too much water can cause water poisoning. What's going on here? Let's first learn about water poisoning, the maximum continuous diuretic rate of the human kidneys is 16 ml per minute, if we take in more water than this standard, or drink water faster than this standard, then there will be a surplus of water in the body, and the excess water will make the cells swell, and then cause dehydration hyponatremia, clinical manifestations will be dizziness, vomiting, weakness, rapid heartbeat and other symptoms, the symptoms of this poisoning are systemic, severe will appear spasms, coma and even life-threatening.

Generally, normal people drink too much water, there is no harm to the body, at most it causes more urination, often runs to the toilet, feels more troublesome, normal people need to drink at least 1500 ml of water a day, about 8 cups or so.

2. For some special people, we must pay attention to drinking water, such as the heart, the kidney function is relatively weak, and the patient who is often edema cannot drink a lot of water, which increases the burden on the heart and kidneys, and easily leads to the aggravation of the disease.

3 For patients with colds, it is good to drink more water, cold and fever will make the body lose water faster, drink more water can compensate for the body water and cool the human body.

Some proper ways to drink water.

However, doctors pointed out that after drinking a lot of water, the human body is prone to tiredness, loss of 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.

It should be pointed out that pregnant women should also drink water in moderation. Drinking too much water in pregnant women can cause or worsen edema. Generally, it is more appropriate for pregnant women to drink 1 liter of water per day, and no more than 1 liter in the third trimester of pregnancy.

Drinking too much water at one time can increase the burden on the heart and kidneys, and it is most harmful to people with heart disease, high blood pressure, kidney disease and edema. It is also not advisable to drink too much water at one time after sweating a lot due to labor or exercise.

Can I get poisoned by drinking too much water?

Normal people drinking too much water will not have much impact on their health, but it may cause an increase in urine output and cause inconvenience in life. However, for some special groups, special attention must be paid to the amount of water to drink, such as edema, heart failure, and kidney failure, because drinking too much water will increase the burden on the heart and kidneys, and it is easy to lead to aggravation of the disease. For patients with diseases such as heat stroke, cystitis, constipation and dryness, drinking more water can have a certain effect on alleviating the condition.

In addition, people should also drink more water when they have a cold and fever, because the rise in body temperature will cause water loss, and drinking more water can promote the body to dissipate heat and help patients recover their health. Pregnant women and people who exercise a lot of water consume more water and should also drink more water.
