I feel that "drinking more water" is a magical thing in China, as if as long as you drink too much water, all illnesses and unhappiness will be "dispelled".
But, do you know? Sometimes drinking too much water can poison people and even kill people.
water is obviously a good thing for health, why drinking more water is good for your health? Water poisoning How terrible is it?
Today, the editor is here to give everyone a popular science, drinking water, this seemingly daily and simple little thing, what exactly needs to be paid attention to.
1. Drink too much water, be careful of poisoning or death!
There is an old saying that "one can have no meals for three days and cannot be without water for one day". This sentence fully demonstrates people's dependence on water.
So why do you still suffer from poisoning and even loss of life after drinking a lot of water?
1 drinking too much water can cause poisoning.Severe or fatal
A woman in Shenzhen drank 3.2 liters of water to hold her urine for a B-ultrasound. She developed nausea and vomiting, hand and foot convulsions and other symptoms after she went to see the doctor. "Poisoning", it took four hours to rescue him before finally getting out of danger.
Coincidentally, Mr. Zhao, a fitness expert in Yangzhou, only drank very little water during the workout and was too thirsty for an hour after the workout. Drink 2L of water.
Later I felt sick all over, not only had a terrible headache, but also showed symptoms of fatigue. After going to the hospital, I found out that it was water intoxication caused by drinking too much water at one time.
It seems normal to drink water such as thirsty, strong15_strongspan14span _strong strong15 _strongspan14span _strongspan18 This terrible phenomenon worries many people.
2 Why is it poisoned by drinking too much water?
Water poisoning is not a poisoning situation caused by the presence of toxic substances in drinking water.It is hyponatremia .
Under normal circumstances, if we drink too much water, various organs of our body will restore the stability of body fluid composition and normal body function by increasing urination, perspiration, and accelerating the frequency and intensity of breathing.
The main reason for drinking water poisoning is, They drink too much water at one time or in a short period of time, a large amount of water enters the body, and the burden on the kidneys increases, which will break the normal balance of our body.
The body is too late to regulate. Excessive water cannot be excreted through the urine, which will cause the concentration of sodium in the blood to decrease. There was dilutional hyponatremia, which is water intoxication.
Drinking water is not like drinking liquids such as soda or alcohol. Drinking too much at a time will not cause immediate discomfort.
Especially for those who are thirsty, gulps and saliva flow into the body down the throat, which is a hearty thing for them, and the possibility of water poisoning is even greater.
2. Is water poisoning really that terrible?
At this time, many friends who love to drink water expressed doubts and worries. If they drink a lot of water a day, will they be poisoned? What should I do if I am poisoned?
1 What conditions are likely to cause water intoxication?
The first thing we need to be clear is that Not only drinking too much water can cause water intoxication. There are many causes of water intoxication. Generally speaking, they include the following:
- The body takes in too much water or receives too much intravenous infusion 14span 14span 14span 14span 14span 14span Excessive secretion of antidiuretic hormones caused by factors, such as blood loss, shock, trauma, and major surgery;
- renal dysfunction, decreased urination during oliguria and anuria.
There is another thing that mothers need to pay special attention to, UNICEF recommends: breastfed infants under 6 months without additional water; 6 months After that, you can't drink too much water, just the right amount.

Generally speaking,Water poisoning can be divided into two types, one is acute water poisoning and the other is chronic water poisoning.
Acute water intoxication, as the name implies, is an acute onset.
When you drink too much water at once, the body organs cannot regulate in time, which leads to the transfer of too much water to the cells, especially brain cells. Too much water will cause brain cells Edema.
At this time the brain will appear due to cell expansion, drowsiness , agitation, headache, mental disorders life.
So be sure to remember: Drink water slowly! Don't worry about drinking water! Many times a small amount!
Symptoms of chronic water intoxication are generally not obvious and can easily be masked by the symptoms of the primary disease.
may appear when the disease is onset weakness, nausea, vomiting, lethargy, etc., weight gain is obvious, and the skin is pale and moist.
Once water poisoning occurs,It is necessary to stop water intake immediately and take action to reverse blood dilution .
is less severe and relieved by excretion of excess water; in severe cases, diuretic can be used to promote urine excretion.
3 Is water intoxication common? Drinking 4 liters of water a day is poisonous?
WHO experts pointed out that “drinking more than 4 liters of water a day may be poisoned, causing damage to brain function and even death”.
What is the concept of 4 liters of water? Compare and calculate with the bottled mineral water we usually drink:
1 bottle of mineral water = 500 ml
1000 ml = 1 liter_ 4 liters of 14 bottles of mineral water
There should be very few people who drink 8 bottles of water a day, right? ? It is true, so the WHO also emphasized thatDrink 4 liters of water a day (approximately 8 bottles of mineral water) It is not common to cause water intoxication.
But if you drink too much water or drink too much at one time, such as drinking 2 liters per hour (about 4 bottles of water) , for more than 2 hours, urine output can not keep up with the increase in blood volume Speed, it is prone to water intoxication.
So the question of how much water you drink and how fast you drink it is a science.
3. Long-term lack of water, the body is quietly "qualitative change"
At this time, someone will say: "I especially don't like drinking water, so that water poisoning will never happen."
p0 span But did you know, long-term lack of water, the body will quietly undergo "qualitative change".When the amount of water loss is 1% of body weight, people will feel thirsty, and physical functions will begin to be affected;
When the amount of water loss is 2% of body weight, motor function will be affected, and Accompanied by decreased appetite, depression, etc.;
When the amount of water loss is 4%-8% of body weight,There will be dry skin, hoarseness, weakness, etc.;
When the amount of water loss is 10% of body weight, it may be life-threatening.
1 body of water, they protest
are lost every minute of our bodies of water, such as the Perspiration, urination, etc. If you don’t drink water to replenish water in time, then every one of your organs will send out a "protest" to you :
- strong15_strong8span _span_span14 strong15_strong8span_span_strong15_span18 If you drink less water, the frequency of urination will be reduced. Some people may think that going to the toilet is a waste of time anyway, which is good. But in fact, reduced urination will create conditions for bacteria. can cause urinary tract infection .
- Intestine
Friends who can’t feces should know that when they have a lot of constipation, they should know that they have shit! Drinking too little water can easily make the stool dry, and you can only squeeze out a little with the strength of drinking milk, and it may be accompanied by bleeding.
- blood ul p0 span ul2158 In the case of insufficient water in the human body, the viscosity of the blood will become higher and thrombosis will easily form. Drinking water can not only quench your thirst, but also reduce the risk of thrombosis .
- Kidney
Insufficient water intake, coupled with evaporation of sweat and skin itself,The decrease in urine output makes some small pieces of urine crystals deposit in the body, which will easily cause stones.
wait to drink water when you are thirsty, in fact, the body is already in a state of lack of water. So remember, usually has to develop the habit of taking the initiative to drink water~
2 How to judge whether the body is dehydrated?
Since the problem of water shortage is not small, how can I judge whether my body is dehydrated?
The simplest and most direct sign of water shortage is thirst. When you feel thirsty, your body is actually telling you that you should drink water.
is followed by poor skin condition. When there is water shortage, the circulation of the skin decreases and the hydration state decreases, and there will be a decrease in elasticity, and even dryness and cracking.
can finally be judged from the color of urine. The color of normal people’s urine is transparent or light yellow ,The amount of water you drink will change the shade of the color accordingly.
If your urine is very dark, or even brown, not only do you need to replenish it immediately, but you will probably have to go to the hospital to check it.
Fourth, drink more water, how should I drink it?
said so much, just want to tell everyone: drinking water is a very simple and trivial matter, but we really need to look into it carefully, it also has a lot to pay attention to.
1 Does everyone drink 8 glasses of water per day to be healthy?
From the amount of water you drink, there is a saying that “drink 8 glasses of water a day to be healthy”. How much is 8 cups of water? Is there more than 4 liters? This standard is inherently vague.
" Chinese Residents' Dietary Nutrient Reference Intake " lists a day's "standard water intake" _span strong18_strong18_strong18.
The official reference value indicates: 6 months to 1 year old,The total daily water intake is 900ml (including milk/food/water), while the daily drinking water for adults is 1500-1700ml. If counted in a cup with a capacity of 200ml, it is indeed 8 cups.
Of course, you don’t have to follow this general recommendation to drink water. How much water a person actually needs to drink depends on their own conditions to decide whether to add or subtract.
2 What should I pay attention to when drinking water?
In small quantities and many times:
Under normal circumstances, it is recommended not to drink more than 1 liter of water per hour (about 2 bottles of ordinary mineral water); To drink. Drinking water in small sips quenches thirst better than sips in large sips, and is more conducive to the body's absorption.
The water temperature should be appropriate:
Drink water with a temperature higher than 65℃ for a long time.It will damage the oral mucosa, tooth enamel, and throat, and increase the incidence of esophageal cancer; the best drinking water temperature should be controlled between 35℃-40℃, and the highest temperature should not exceed 45℃.Control the amount of water consumed by special populations:
There are diabetes , heart disease, kidney disease and other people who can’t use the standard drinking water. It is best to follow the doctor’s advice to drink water, so as not to increase the burden on the heart or kidneys.
3 drinking water, the size of the disease away from your
University of Birmingham had a study found that as long as the Half an hour before each meal, insist on drinking a glass of 500ml of water for 3 months, and you can lose 2kg-4kg.
So if you drink the right water at the right time, certain physical problems will gradually change in the right direction.- Get up early and drink a glass of warm water to prevent stains;

- Drinking a glass of water 1-2 hours before going to bed can reduce the blood viscosity of
- span Prevent constipation and urinary tract stones. I won't explain this much, I understand everything that I understand.
No matter how good things are used inappropriately and moderately, they will have negative effects.
The purpose of this article is to let everyone get a more scientific way of drinking water through my sharing.
