Drink water slowly, not in large gulps. Drinking too much water at once can dilute stomach acid, leading to a decrease in the gastrointestinal tract's absorption capacity. Large amounts of water can also accelerate the loss of salt in the body, meaning the more you drink, the more salt you lose. A large amount of water accumulating in the stomach and intestines can also cause a feeling of bloating and is detrimental to health. When you are extremely thirsty, you should especially avoid drinking in large gulps, as this can make it difficult for the stomach to adapt, leading to adverse consequences.
Do not wait until you are thirsty to drink water. Thirst indicates that your body's fluid balance is disrupted and your cells are starting to become dehydrated. By the time you feel thirsty, it is too late to drink. You should develop the habit of drinking water at regular times. It is best to drink a glass of plain water after brushing your teeth in the morning, another glass around 10 AM, one before lunch, one at 3 PM, and another before going to bed at night. The daily water intake for a healthy person should be at least 2000 milliliters.
Do not drink repeatedly boiled water. If water is boiled over and over again, as the water evaporates, the concentration of inorganic salts will increase accordingly. Among these, nitrite is particularly harmful to the human body. Long-term consumption can, in mild cases, affect the stomach and intestines, and in severe cases, lead to poisoning.
Do not drink overly hot boiled water. Water that is too hot can scald the oral cavity, pharynx, esophagus, and gastric mucosa, causing congestion. Over time, this can lead to inflammation.
Drink warm salt water, not ice water. In the summer, many people choose to drink ice water or cold beverages after sweating, but this is not scientific. Doing so can cause pores to constrict, making it difficult for the body to dissipate heat. This can lead to a buildup of residual heat, which in turn can easily cause heatstroke. The correct method is to drink more light salt water to replenish the lost salt and fluids. When salt water enters the body, it quickly penetrates the cells, providing timely rehydration for the body that is constantly sweating and dehydrated.
