What are the dangers of drinking too much water at one time?

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 at one time can bring a lot of harm to the body.

1. Drinking too much water will increase the burden on the kidneys. The human body is detoxified through urine, and the main component of urine is water, and all urine is filtered by the kidneys, so if you drink too much water, it means that the kidneys filter more, which will increase the burden on the kidneys.

2. Drinking too much water can cause water poisoning. The sustained maximum diuretic rate of the human kidneys is 16 ml per minute, if the amount of water ingested by the human body exceeds this standard, or the speed of drinking water exceeds 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 and hyponatremia, which will be clinically manifested as dizziness, vomiting, weakness, rapid heartbeat and other symptoms, the symptoms of this poisoning are systemic, and severe spasms, coma and even life-threatening.

3. When you have a cold, the more water you drink, the better. When you have a cold, doctors tell patients to drink more water, because water can accelerate detoxification and relieve the symptoms of colds, and when people have a cold, the body is also easy to lack water, so it is beneficial to increase the intake of water appropriately, but it is definitely not that the more you drink, the better, but according to individual differences, you should increase the amount of water you drink appropriately, and the amount of water you drink at one time should not be too much.

The amount of water per person should be determined according to the individual's situation, 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 or too quickly at one time is not good for the body, especially for the elderly.

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.

You can't drink water too quickly, you should drink it slowly and sip like tea, so that it can really replenish the body.

It can easily cause water poisoning.

Reason: The metabolism of water in the human body mainly depends on the kidneys, which are not omnipotent, and their ability to eliminate water is limited, about 1 hour. That is, if a person drinks more than 1L of water in 1 hour, then the kidneys will not be able to remove the excess water.

Therefore, it is easy to cause water poisoning due to drinking too much water at one time. Tiredness, loss of appetite, dizziness, vomiting and other phenomena can occur. These symptoms occur because drinking too much water dilutes the blood, affecting the oxygen exchange of brain cells, and the brain becomes sluggish.

Drinking too much water will increase the burden on the kidneys, and the amount of urine excreted by the kidneys in a day is about 1500-2500ml. If you drink too much water, it means that the kidneys have to filter more, which will increase the burden on the kidneys. If you drink more water than the amount of urine excreted by the kidneys, it can lead to water poisoning, which can be dangerous if you drink too much water.

Because when the water intake is too much, it will cause the kidneys to be unable to filter and discharge it in time, and then it will destroy the normal operation of cells. When there is too much water and cannot be discharged, symptoms such as fatigue, dizziness, nausea, vomiting, etc., and in severe cases, it can also lead to cerebral edema, increased intracranial pressure, headache, projectile vomiting and other symptoms, which can be life-threatening at this time. Therefore, it is recommended to develop good living habits, and the total amount of water intake per day is generally less than 3000ml, which is conducive to health.
