Experts explained that the lady's disease was mainly because she belongs to patients with glaucoma, and drinking a lot of water at one time is just a fuse. After drinking a large amount of water, the blood in the human body was diluted, and the plasma penetration pressure decreased, which caused a large amount of water in the eyeball to cause a large amount of water, resulting in an instant increase in intraocular pressure. Ordinary people can regulate intraocular pressure through their own metabolism, but for the high -risk people of glaucoma, their ability to regulate the eye pressure is poor, and the excess room water cannot be excluded in time. Too much water at a time may increase the intraocular pressure, which will lead Oncology.

Drinking water is misunderstanding, have you "stepped on the thunder"?

In recent years, there have been more and more about drinking water on the Internet, but many of them have no scientific basis. The following editors have summarized a lot of drinking water misunderstandings. Let's take a look.

Misunderstanding 1: Drink water after thirst

In fact, feeling thirst is already a signal of obvious water shortage, so you should not feel thirsty before drinking water. When the body fluid in the human body consumes about 1%of weight, while thirsty feels, the plasma osmotic pressure in the body increases, and the ability of physical activity will be affected.

When it reaches 2%-4%, the human body is already dehydrated. While feeling thirsty, the urine will decrease. The color of the urine is not normal with yellow transparency or white. It will increase, at this time, our working ability and cognitive ability will be reduced. When it reaches 4 % to 8 %, the human body is already in a moderate dehydration. At this time, the symptoms of dry skin and non -elastic, dry tongue, hoarseness, fast heart rate, and irritability will cause blood pressure to decrease, or even even life threatening. So don't wait until thirsty before drinking water. Drink water actively and drink about 200 ml of water each time.

Misunderstanding 2: Get up a cup of fresh salt water early

Some people think that drinking a cup of fresh saline after getting up early can discharge the accumulated toxins in the body and promote the cycle of renal function. However, the salt intake of Chinese residents has exceeded the standard every day, so adding salt to the water will only increase the burden on the body. Drink less alcohol, do not consume excessive salt, reduce staying up late, and so on. It is really "detoxification". The human body is not a toilet.

In addition, during a long time of sleep, the body will have some hidden sweat and urine secretion, which will lose the water in the body. Therefore, although you may not feel thirsty when you get up, in fact Causes blood viscosity, so you can drink some pure water in the morning to reduce blood viscosity and increase the circulating blood capacity.

Misunderstanding 3: Drink more hot water

Many people in today's society think that "drinking more hot water" is a healthy lifestyle. However, research shows that hot drinks exceeding 65 ° C may cause cancer. This is because our esophageal mucosa is very fragile. The temperature of the water is too high, which is very easy to cause the esophageal mucosa to be burned. What is more dangerous is that the esophageal perception of temperature is not sensitive. Water is a chronic stimulation for esophageal mucosa. The damage has not been repaired, and new trauma has been encountered. In the long run, it will increase the risk of cancer. For the delicate esophagus, water from 10 ° C to 40 ° C is the most suitable. Hot water exceeding 65 ° C will cause burns, so don't be anxious whether it is drinking water or eating.

Misunderstanding 4: Drinking thousands of boiling water is harmful to health

Many people think that after repeatedly cooked water contains a large amount of nitrite, there will be risk of carcinogenic. In fact, according to the People's Daily, after more water heating, the content of nitrite will indeed increase, but the increase is small. Therefore, even the water that has been heated many times, the content of nitrite contains is very small, which is safe.

Misunderstanding 5: You can use milk and juice instead of water

Many young people now think that juice and milk not only contain water but also more vitamins and proteins. Use them to replace water to supplement the nutrition while supplementing water, and get two birds with one stone. In fact, first of all, the juice contains a lot of sugar. Use fruit juice to replace water to make the body's inges in sugar that exceeds the standard, resulting in obesity. Source 丨 pixabay

Secondly, the juice usually contains additives, which will have adverse effects on the stomach. There is more protein in milk, and a large amount of drinking will increase the burden on the liver and kidney. Therefore, we still need to drink water normally in daily life, and try not to use other drinks instead.

Drink the water posture correctly

First, it is best to drink warm water: cold drinks may cause gastrointestinal discomfort or even diarrhea; hot water will destroy the esophagus mucosa and stimulate mucosal hyperplasia, thereby inducing esophageal cancer. Therefore, the most suitable temperature for drinking water is 10 ° C-30 ° C.

Second, do not drink water: Many people like to drink water when they are thirsty. The correct pose of water should be a sip of water, and slowly swallow it multiple times.

3. Drinking water varies from person to person: Many people like to stipulate how much water they need to drink every day, but it is not necessary. Healthy people can judge whether they need to drink plenty of water through urine color: the normal urine color should be pale yellow, and if the color is too dark, it should be supplemented by water; if the color is light, it may be too much water.

4. Pay attention to time after the barrel water is opened: In addition, many families are now used to drinking barrel water, thinking that this is clean and hygienic, but the barrel water is opened for a long time, and the bacteria will slip along the water inlet. If you do n’t drink it in the short term The bacteria in the water will exceed the standard, and pure water will no longer be pure.

It can be seen that drinking water is also asked by university. It is recommended that you usually develop good habits, drink water regularly, a small amount.
