Is it really inappropriate to drink drinking water and mineral water after 3 days?

Answer: Not suitable for drinking: Here are 17 shocking truths about drinking water.

1, tap water

Some people are used to getting up in the morning, turning on the tap and drinking a glass of tap water, which is not right. The tap water that has been stopped all night and the tap water in the water pipe are still. This water, the metal pipe wall and metal cavity of the faucet will produce hydration reaction, forming metal polluted water, and the residual microorganisms in tap water will also multiply in large quantities. This kind of water contains a lot of substances harmful to human body, and may also contain Legionella, an acute respiratory infectious disease that threatens human health.

So when you turn on the tap in the morning, the tap water that comes out at first is inedible stagnant water. People who have this habit should correct it immediately so as not to damage their health.

2. Long-term boiled water

If boiled water is left for a long time, the nitrogen-containing organic matter in it will be continuously decomposed into nitrite. In particular, boiled water stored for a long time is bound to be contaminated by bacteria. At this time, the decomposition of nitrogen-containing organic matter will be accelerated and more nitrite will be formed. After drinking such water, nitrite will combine with hemoglobin and affect the oxygen transmission function of blood.

Therefore, in the thermos, the residual water that has been boiled for many days and the water that has been boiled for a long time on the stove have changed their composition and cannot be drunk. You should drink boiled water for no more than 24 hours.

In addition, bottled and barreled purified water and mineral water should not be stored for too long. Bottled or barreled purified water and mineral water should not be drunk for more than 3 days.

3. Salt water

Some people think that drinking light salt water is good for health, so drinking light salt water in the morning is really wrong. Drinking light salt water is good for your health. It is necessary to replenish water after sweating in summer, but replenishing water in the morning is not only useless, but also a wrong practice that harms your health.

According to physiological research, people don't drink water during the whole night's sleep, but breathing, perspiration and urination are all going on, and these physiological activities consume a lot of water. When I got up in the morning, my blood had become concentrated. At this time, if you drink a certain amount of boiled water, you can quickly dilute the blood and correct hypertonic dehydration at night. Drinking salty boiled water will aggravate hypertonic dehydration and make people thirsty. What's more, the morning is the first peak of human blood pressure rise. Drinking salt and boiled water will raise blood pressure and endanger health.

Step 4 drink

It is best not to drink juice, cola, soda, coffee, milk and other drinks in the first glass of water in the morning. Most carbonated drinks such as soda and cola contain citric acid, which will accelerate the excretion of calcium during metabolism and reduce the content of calcium in blood. Long-term drinking will lead to calcium deficiency. Other drinks are good for urination. Drinking water in the morning can not only effectively replenish the water that the body lacks, but also increase the collective demand for water, resulting in water shortage in the body.

Fruit juice, milk and coffee should not be used as the first cup of drinks in the morning, because these substances can not provide the most needed water for the body at this time, but also make the body digest and absorb the gastrointestinal tract in a state of water shortage, which is not conducive to health.

Therefore, everyone should remember that the above four kinds of water are not allowed to be drunk in the morning for their own health.

Now, more and more people pay attention to drinking water; But only a few people can really drink. Drinking at the wrong time, without considering the content and thinking, can only prove that you just drink water, but you don't necessarily drink the right water. In this era when caring for the body has become popular, drinking water, once considered the simplest, will also become a profound knowledge.

5, hydrating before meals is the most nourishing stomach

Do you need to replenish water before eating? Wouldn't that dilute gastric juice and affect digestion? Western food has the steps of appetizing before meals. The reason is to use soup to stimulate appetite, lubricate the esophagus and prepare for meals. Then, hydrating before meals means the same thing. Before entering solid food, drink half a cup (about 100 ml), which can be fruit juice and yogurt at room temperature, warm crystal sugar chrysanthemum water or light tea, or a small bowl of thick appetizing soup, all of which are good ways to nourish the stomach.

6. Drink more invisible water

Some people don't seem to drink water all day long, because the water intake from food is enough to meet their needs. Food also contains water, such as rice, whose water content reaches 60%, and the water in porridge is even richer. It is not difficult to see that the water content of vegetables and fruits generally exceeds 70%. Even if you only eat 500 grams of fruits and vegetables a day, you can get 300~400 ml of water (with two breasts). In addition, the daily diet pays attention to the combination of dry and wet, and it is not difficult to ingest 1500~2000 ml of water for three meals. It is better to make full use of the opportunity of eating three meals to replenish water. Choose more fruits and vegetables and salty soup porridge, which has good hydration effect.

7. Remember water food.

The so-called diuretic food refers to the food that can increase the water excretion of the human body, such as watermelon, coffee, tea, etc., which contains diuretic ingredients and can promote the formation of kidney urine; There are also coarse grains, vegetables and fruits containing dietary fiber, which can combine a lot of water in the intestine and increase the weight of feces; Spicy and stimulating ingredients can promote the relaxation of capillaries on the body surface, make people sweat and lose water on the body surface. Tonifying and benefiting are both means to achieve water balance in the body.

8. Drinking has nothing to do with beauty.

The body lacks moisture and the skin looks dry and dull; Drinking too little water is also easy to dry stool or even constipation, and the skin is prone to acne. Despite this, the effect of hydration on skin and skin color is limited, but now many drinks containing vitamins are all under the banner of beauty. For example, a milk-containing beverage contains vitamin B6, and its product claims to "make skin smooth and tender", but now there are quite a few beverages containing this "beauty vitamin". Orthodox monographs on nutrition have not mentioned its beauty function. Fortunately, eating more is not dangerous, but also can prevent the occurrence of coronary heart disease, which is also beneficial and harmless.

9. "killing" in water

Boiled tap water may contain carcinogenic high chlorine compounds, and if it is left for a long time (overnight), the water quality will age.

Now there are also various water processors in China, similar to the once popular mineral spring pots. Such equipment has the problem of follow-up maintenance, just like drinking fountains, which may become the source of secondary pollution of drinking water.

10, knowledge of drinking sports drinks

Before and after strenuous exercise, white water or high-concentration juice should not be supplemented, but sports drinks should be supplemented. Sports drinks should contain a small amount of sugar, sodium salt, potassium, magnesium, calcium and various water-soluble vitamins to supplement what the body loses and needs during exercise. Drinking white water will cause blood dilution, perspiration will increase sharply, further aggravating dehydration. The concentration of sugar in fruit juice is too high, which prolongs the emptying time of fruit juice from the stomach and leads to stomach discomfort during exercise. Specially designed concentrations of inorganic salts and sugar in sports drinks can avoid these adverse reactions. The temperature of sports drinks is also very particular. Too high is not conducive to lowering body temperature and heat dissipation. Too cold can cause gastrointestinal spasm. Generally, it tastes cold, and the temperature is around 10.

1 1, beware of sour drinks.

Citric acid is often used as a flavoring agent for various fruit juice drinks. When you eat too much citric acid, a lot of organic acids suddenly enter the human body. When the intake exceeds the body's ability to deal with acid, the PH value in the body will be unbalanced, leading to acidosis and making people tired and sleepy. Especially in midsummer, due to the hot weather and sweating, the human body will lose a lot of electrolytes, such as potassium, sodium, chlorine and other alkaline components, and a large number of sour drinks are more likely to make body fluids acidic. Therefore, it is not advisable to drink too many sour drinks containing organic acids in summer.

12, the trap of sweet drinks

If you think of drinks first when you are thirsty, it is quite dangerous. The sugar content of cola, sprite and Fanta is 1 1%, which exceeds many fruits such as watermelon, apple and citrus. A can of 350 ml coke contains the energy equivalent to a piece of bread, a corn or 250 g fruit. The sugar content of various fruit juices is equivalent to this, even higher than it. Pulse, her/him, activation and other vitamin drinks that look like water also contain 3% sugar. If you drink a large bottle (600 ml), it will have a considerable impact on your weight. I did hear about the unfortunate experience of someone suffering from diabetes because of binge drinking sweet drinks.

13, disadvantages of light salt water

Pale salt water refers to saline water with physiological concentration, and the salt content per 100 ml is about 1 g. It has several uses in daily life: first, it can supplement the water and sodium lost by the body after sweating; Second, replenish the water and salt lost in the intestine after diarrhea and maintain electrolyte balance; Third, gargling with light salt water can remove bacteria in the mouth and reduce redness and swelling caused by oropharyngeal inflammation. However, light salt water is not suitable for people with poor heart function and high blood pressure, especially when blood viscosity is the highest in the morning. Drinking light salt water will aggravate dry mouth and promote blood pressure.

14, see through the "pattern" water

Pure water, after multiple filtration, removes all kinds of microorganisms, impurities and beneficial minerals, highlighting the safety of drinking. This is soft water. Many people think that long-term drinking is not nutritious and harmful to health, but this view has not been confirmed.

Mineral water is a natural resource, which is mined from the depths of the stratum. Rich in rare minerals and slightly alkaline, it should be more conducive to health, but the possibility of organic pollution is not ruled out.

Mineral water is an artificial mineral water made by adding mineral concentrated solution in pure water according to the proportion of human body concentration, which marks a new height of drinking water technology.

15, loves sports and can replenish water.

Exercise hydration should master the following principles:

A. if you are thirsty, you can't make up for it. Because when you feel thirsty, you will lose 2% weight.

B. replenish water before, during and after exercise. Supplement 250-500ml； 2 hours before exercise; Give150-250ml immediately before exercise; During exercise, supplement 15 ~ 20min120-240ml; After exercise, according to the weight loss during exercise, 1 kg should be increased.

16, it is unwise to replenish water frequently.

When the body is in a stable state, it is enough to normally replenish 1000~2000 ml of water every day to keep the urine clear and sufficient. But if you drink a lot of water consciously or unconsciously, there is a problem. First of all, your body may be dehydrated. In a high temperature environment, sweating a lot or eating a lot of salt may be millions, and you need to replenish water. Secondly, if there is hyperglycemia, pituitary or renal insufficiency; Or in infectious diseases such as influenza and fever; Or patients with urinary system inflammation or even hyperuricemia can also take the initiative to drink more water. It is really unnecessary for a healthy person to drink more than 2000ml/ day without feeling thirsty. This is just another test of his kidney function.

17, vitamin c drinks are useless.

Many newly listed drinks contain vitamin C, and the benefits of vitamin C need not be said. In order to prevent deficiency, the human body needs to supplement 60~ 100 mg every day. The vitamin C content of queer is 3 ~ 30mg/ 100ml, the pulse rate is 25 ~ 50mg/ 100ml, and that of she is 15mg/ 100ml. In other words, drinking a bottle of this beverage can meet the daily vitamin C requirement. So, what about drinking 2 bottles, 3 bottles or even more? Can vitamin C poisoning happen? Fortunately, vitamin C has a wide range of safety, but don't think that the more the better. Excessive intake can cause urinary calculi, osmotic diarrhea and high-dose vitamin C dependence.
