Many people often think of drinking water when they are thirsty, and they often gulp it down, which is also wrong. Drinking water too fast and too hard is bound to swallow a lot of air together, which is easy to cause hiccups or bloating. Therefore, it is best to put water in your mouth first, and then drink it slowly, especially for people with weak stomach and intestines.

Don't drink water when you are thirsty. Drink water in moderation between meals, preferably once every hour. People can also judge whether they need to drink water according to the color of urine. Generally speaking, human urine is light yellow. If the color is too light, maybe they drink too much water. If the color is too dark, it means that they need to add more water.

Drinking less before going to bed and drinking more before going to bed is also the principle of drinking water correctly, because drinking too much before going to bed will cause eyelid edema, and running to the toilet in a nightclub will make the quality of sleep not high. After a night's sleep, the body loses about 450 ml of water, which needs to be replenished in time in the morning. Therefore, drinking a glass of water on an empty stomach after getting up in the morning is beneficial to blood circulation, and it can also promote brain lucidity and make the thinking of this day clear and agile.

Drink more boiled water instead of raw water. Boiling water for 3 minutes can evaporate chlorine and some harmful substances in the water, and at the same time, it can keep the necessary nutrients in the water. Drinking raw water is very harmful, because chlorine in tap water will interact with residual organic matter in boiling water, which will increase the chances of bladder cancer and rectal cancer.

Drink fresh boiled water, not water that has been left for too long. Fresh boiled water is not only sterile, but also contains more than a dozen minerals needed by the human body. But if the time is too long, or if you drink the boiled water in the automatic water heater overnight, not only will you lose all kinds of minerals, but you will also contain some harmful substances, such as nitrite. The resulting nitrite poisoning is not uncommon.
