Getting up in the morning to drink five kinds of water damages health:
Ice water Many people like to get up in the morning to drink a glass of ice water, especially in the summer, in fact, this is very unscientific. Drinking ice water can easily cause gastric mucosal vasoconstriction, affect digestion, stimulate the gastrointestinal tract, accelerate the gastrointestinal motility, and even cause intestinal cramps, leading to abdominal pain and diarrhea. Normal people drink ice water, especially sweet drinks, which can cause stomach problems after drinking on an empty stomach.
In addition, ice water first stimulates the throat, blood vessels in the state of congestion will suddenly shrink, blood will be reduced, and the bacteria hidden in it will take advantage of it, which may cause sore throat, dullness, or cold and cough. Has a negative impact on physical health.
morning. Excessive drinking of ice water will also affect the development and physiological functions of the reproductive system. Especially for some girls, whether it is menstrual period, drinking ice water or cold drinks, it will cause menstrual disorders and dysmenorrhea. Cold air gathered in the palace and even buried the bane of infertility after marriage.
Excessive drinking of ice water for boys can also affect sperm development. In addition, ice water can cause damage to the throat, vocal cords, respiratory system, and the like.
It is best not to drink commercially available juice, cola, soda, coffee, milk, etc. for the first glass of water in the morning. Most carbonated beverages such as soda and cola contain citric acid, which accelerates the excretion of calcium during metabolism and lowers the calcium content in the blood. Long-term drinking can lead to calcium deficiency. Other beverages are good for urination. Drinking in the morning can not effectively replenish the water that the body lacks. It also increases the collective demand for water, which in turn causes water shortage in the body.
Juice, milk, and coffee should not be used as the first drink in the morning, because these substances can not provide the most needed water at the time, and the body will be digested and absorbed in the absence of water. Conducive to the health of the body.
Some people think that drinking salt water is good for their health, so drinking salt water in the morning is a mistake. Drinking light salt water is good for health, which is necessary for replenishing water after sweating in the summer. It is not only beneficial for morning water supplementation, but also a misconduct that is harmful to health.
Physiological studies suggest that people do not drink drip during sleep all night, but breathing, perspiration, and urinary dysfunction are in progress, and these physiological activities consume a lot of water. When getting up in the morning, the blood has become concentrated. At this time, if you drink a certain amount of boiled water, the blood can be diluted quickly, and the hypertonic dehydration at night can be corrected. Drinking salt water instead of aggravating hypertonic dehydration makes it easy to dry. Moreover, the morning is the first peak of the rise in blood pressure in the human body. Drinking salt and boiling water will make blood pressure higher and endanger health.
After a long time of boiling water, the nitrogen-containing organic matter will be continuously decomposed into nitrite. In particular, the boiling water that has been stored for a long time is inevitably contaminated with bacteria. At this time, the decomposition of nitrogen-containing organic matter is accelerated, and the production of nitrite is more. After drinking such water, the combination of nitrite and hemoglobin will affect the oxygen transport function of the blood.
Therefore, the residual water that has been boiled many times in the thermos for many days, and the water that has been boiled for a long time on the stove, has changed its composition and cannot be drunk. You should drink water that is boiled for no more than 24 hours.
In addition, bottled, bottled pure water, mineral water should not be stored for too long. Large bottles or barrels of pure water and mineral water should not be consumed for more than 3 days.
Tap water is used to getting up in the morning to open the tap and take a cup of tap water to drink. This is not right. The tap water in the faucet and the water pipe that is deactivated overnight is static. These water and metal pipe walls and the metal chamber of the faucet will produce hydration reaction, forming metal-contaminated water, and the residual microorganisms in the tap water will also multiply. A large number of substances harmful to the human body may also harbor an acute respiratory infectious disease, Legionella, which threatens human health. Therefore, the tap is unscrewed in the morning, and the tap water that originally flows out is non-drinkable stagnant water, so those who have this habit should correct it immediately so as not to damage their health.
Getting up and drinking five kinds of water in the morning can damage your health.
