16 kinds of "killer" hidden in clean water

Stopping overnight taps and tap water in the water pipes are still. These water and metal pipe walls and faucet metal chambers will produce hydration reactions, form metal contaminated water, and residual microbes will grow in tap water. This water contains A large number of substances harmful to the human body may also harbor an acute respiratory infection pathogen, Legionella, which threatens human health.

1, the "killer" in the water

Tap water boiled may contain carcinogenic hyperchloric compounds, such as aging over a longer period of time (overnight).

Nowadays, various household water treatment machines have also appeared on the scene. Similar to the once-vibrant mineral pots, such equipment has the problem of follow-up maintenance. Just like drinking fountains, it may become the source of secondary pollution of drinking water.

2, tap water

Some people get used to getting up in the morning to turn on the tap and take a glass of tap water to drink. This is a mistake. Stopping overnight taps and tap water in the water pipes are still. These water and metal pipe walls and faucet metal chambers will produce hydration reactions, form metal contaminated water, and residual microbes will grow in tap water. This water contains A large number of substances harmful to the human body may also harbor an acute respiratory infection pathogen, Legionella, which threatens human health.

Therefore, when you turn on the tap in the early morning, the tap water that was originally discharged is non-drinkable, so people who have such habits should correct it immediately to avoid harming their health.

3, long home of boiling water

After boiling water for a long time, nitrogen-containing organic matter will be continuously decomposed into nitrite. In particular, water stored for too long, it is inevitable that bacterial contamination, decomposition of nitrogen-containing organic matter accelerated at this time, nitrite is born more. After drinking such water, the combination of nitrite and hemoglobin will affect the oxygen transport function of the blood.

Therefore, the water that boiled many times in the thermos bottle and the boiling water that has been boiling 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, bottled pure water, mineral water should not be stored too long. Large bottles or barrels of pure water and mineral water should not be drunk for more than 3 days.

4, salt water

Some people think that drinking light salt water is good for your health, so you drink light salt water in the morning. This kind of familiarity is indeed wrong. Drinking light salt water is good for health, which is necessary to add moisture after sweating in the summer, but it is not beneficial for supplementing water in the morning, and it is still a wrong practice to endanger health.

Physiological research suggests that people do not drip during the whole night's sleep, but breathing, perspiration, and urinary tract are in progress. These physiological flows consume a lot of water. When you wake up in the morning, the blood has 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 salt water again will aggravate hyperosmolar dehydration, and it will add dry mouth. Moreover, the morning is the first peak in human blood pressure, drinking salt water will make blood pressure higher and harm health.

5, drinks do not provide the most needed water

The first glass of water in the morning is best not to drink commercially available juice, cola, soda, coffee, milk and other beverages. Most carbonated beverages such as soft drinks and cola contain citric acid, which accelerates the excretion of calcium during metabolism and reduces the content of calcium in the blood. Long-term drinking leads to calcium deficiency. While other beverages are beneficial to urination, drinking in the morning can not only effectively increase the lack of moisture in the body, but also increase the collective demand for water, but cause water shortage in the body.

Juice, milk, and coffee are also not suitable as the first drink in the morning. Because these substances do not provide the most needed moisture for the body at this time, they also allow the body to digest and absorb the gastrointestinal tract in the absence of water. It is good for your health.

Therefore, everyone must remember for their own health that the above four types of water cannot be drunk in the early morning.

7, drink invisible water

Some people don't seem to drink water all day long. That's because the amount of water in the food is sufficient to meet the needs. Food also contains water, like rice, which contains 60% of water content, and porridge, it is even more watery. Turning over the food ingredients does not lose face. The water content of vegetables and fruits is generally more than 70%. Even if only 500 grams of fruits and vegetables are eaten each day, 300 to 400 milliliters of water can be obtained (with two pregnant women). In addition to daily diet, it is dry and thin, so getting 1500-2000 ml of water from three meals is not a problem. It is better to make full use of the opportunity to eat three meals a day to make up for the water, and choose fruits and vegetables and unsalted soup porridge.

Specific concentrations of inorganic salts and sugars in sports drinks will avoid these adverse reactions. The temperature of sports drinks is also exquisite, too high is not conducive to reducing body heat, cold will cause gastrointestinal spasm, generally should be cool, temperature is about 10.

11, guard against sour drinks

Citric acid is used as a flavoring agent in various fruit juice beverages, and citric acid is consumed excessively. A large amount of organic acids suddenly enter the body. When the intake exceeds the body's ability to handle the acid, the pH of the body will be unbalanced. The production of acidemia makes people tired and sleepy.

The vitamin drinks that look like water, such as pulse, her/him, activation, also contain 3% of sugar. If you drink a large bottle (600ml), the effect on weight is considerable. It is also true that someone has been suffering from diabetes because of overeating sweet drinks.

13, bad salt water

Light salt water refers to the salt water that corresponds to the physiological concentration.

About 1 gram of salt, it has several uses in daily life: First, after the sweat, add water and sodium lost in the body; Second, after diarrhea, add water and salt lost from the intestine to maintain electrolyte balance; Light salt water gargle can clear bacteria in the mouth and reduce inflammation caused by inflammation of the oropharynx.

Mineral water is a kind of natural resource that is mined from the depths of the stratum. It contains abundant rare minerals and is slightly alkaline. It should be more conducive to health, but organic pollution may not be ruled out.

Mineral water, artificial mineral water prepared by adding mineral concentrate in proportion to human body concentration in pure water, marks a new height of drinking water technology.

16, vitamin C drinks drink unproductive

Many of the newly listed beverages contain vitamin C. Needless to say, the benefits of vitamin C need to be increased by 60 to 100 milligrams every day to prevent a deficiency. "Queer" has a vitamin C content of 3 to 30 mg/100 ml, a "pulse" of 25 to 50 mg/100 ml, and a "she" of 15 mg/100 ml, which means that one bottle of this kind of drink is obtained.
