Drinking water, how simple a thing, but there are many "red lines", such as a saying about drinking water since childhood, perhaps the old man in your family has also warned you that you must not drink water when eating, otherwise it will dilute the gastric juice! Is there any truth in what the old man said?
Not only during meals, but also after eating, some people say that they can't drink water immediately, which is not good for the stomach. In fact, there is no scientific basis for this claim. On the one hand, when people are in an empty state, the stomach secretes very little gastric acid, even if when eating, the stomach will secrete more gastric acid for digestion, which is the gastric juice we mentioned, but it is also within a reasonable range and will not be diluted.
If you really want to achieve the degree of dilution, it usually needs to reach about 2L of aqueous solution before it is possible to change, which is currently impossible for the human body to achieve.
On the other hand, if there is a lot of water in the food during the meal, especially cucumbers, winter melons, loofahs, pumpkins, etc., which have high water content, it is easy for water to enter the gastrointestinal tract if you do not drink water.
In this way, there are no adverse reactions, for special groups of children, because the gastrointestinal function is not complete, and it will not affect the concentration of gastric juice and PH value because of the moderate amount of water during meals, so you don't have to worry.
In addition, you also need to consider a situation, whether before, during, or after meals, do not think that drinking water after thirst is the normal way. You must know that when the body has obvious thirst, in fact, the body fluid has begun to lose, and it can even reach more than 1% of body weight.
In addition, we also need to be clear about a concept, if the amount of body fluid loss can reach 2%~4%, it means that the body begins to dehydrate, and the amount of urine will also decrease. If you want to verify this, the solution is very simple, mainly depends on the color of your urine.
When the color of your urine is already dark yellow, it means that you are dehydrated, and your learning and work efficiency will be greatly reduced. If you are extremely thirsty, you will be dehydrated to the next level, i.e. dry skin, decreased elasticity, hoarseness, chapped mouth, heart rate changes, and mood swings will become very large.
Therefore, it is normal to replenish water in time at this time. At the same time, it is necessary for everyone to pay attention to the fact that do not wait for the body to lack water before drinking, the correct way is to establish a good awareness of drinking water, even if you are busy with study and work, do not forget to drink water often.
Don't drink too much water each time, 100~200ml is appropriate, and the water resources for drinking are not recommended to choose soft drinks, but ordinary warm water, or mineral water, pure water, which is healthy drinking water, which can be supplied to the body normally every day.
