after a night’s sleep, the water lost by the human body is about 450 ml, which needs to be supplemented in time in the morning. Therefore, drinking a cup of warm boiled water on an empty stomach after getting up in the morning is conducive to blood circulation, can also promote brain wakefulness and make the thinking of this day clear and agile.
How about drinking water on an empty stomach in the morning? How to drink water in the morning is the healthiest
what water should not be drunk on an empty stomach in the morning
salt boiled water
some people think that drinking light saline is beneficial to health, so they drink light saline in the morning. This understanding is really wrong. Drinking light salt water is good for health, which is necessary to replenish water after sweating in summer, but it is not only useless for replenishing water in the morning, but also a wrong practice harmful to health.
physiological research shows that people do not drink water all night, but breathing, perspiration and urinary tract are in progress. These physiological activities consume and lose a lot of water. When you get 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 the hypertonic dehydration at night. Drinking salt and boiled water will aggravate hypertonic dehydration and make your mouth dry. Moreover, the morning is the first peak of human blood pressure rise. Drinking salt and boiled water will make blood pressure higher and endanger health.
fruit juice, carbonated drinks, etc.
the first glass of water in the morning is best not to drink commercially available fruit juice, coke, soda, coffee, milk and other drinks. Carbonated drinks such as soda and cola mostly contain citric acid, which will accelerate the excretion of calcium and reduce the content of calcium in blood during metabolism. Long term drinking will lead to calcium deficiency. Other drinks are conducive to urination. Drinking in the morning can not effectively supplement the water lacking in the body, but also increase the collective requirements for water, resulting in water shortage in the body.
fruit juice, milk and coffee should not be used as the first drink in the morning, because these substances can not provide the water most needed by the body at this time, and will make the body digest and absorb the gastrointestinal tract in the state of water shortage, which is not conducive to the health of the body.
the water from the tap at first
some people are used to turning on the tap in the morning and drinking a cup of tap water. This is wrong. The tap water in the faucet and water pipe that have been out of service for one night is still. The water, metal pipe wall and metal chamber of the faucet will produce hydration reaction to form metal polluted water, and the residual microorganisms in the tap water will also reproduce. This water contains a large number of substances harmful to human body, and may also contain an acute respiratory infectious bacteria threatening human health & mdash; Legionella.
therefore, when the tap is turned on in the morning, the tap water initially flowing out is dead water that can not be drunk. Therefore, people with this habit should correct it immediately to avoid damaging their health.
long boiled water and purified water
long boiled water will continuously decompose nitrogen-containing organic matter into nitrite. In particular, the boiled water stored for too long will inevitably be polluted by bacteria. At this time, the decomposition of nitrogen-containing organic matter will accelerate, and the formation of nitrite will be more. After drinking such water, nitrite combines with hemoglobin, which will affect the oxygen transport function of blood.
therefore, the composition of the boiled water in the thermos for many days, the residual water boiled for many times, and the water boiled on the stove for a long time have changed and can not be drunk. You should drink boiled water for no more than 24 hours at a time.
in addition, bottled and barreled purified water and mineral water should not be stored for too long. Large bottles or barrels of purified water and mineral water should not be drunk for more than 3 days.
