Anonymous users2024-02-12As we all know, seawater is not drinkable, and the crew who go to sea, as well as those who often live near the sea, know that seawater is not drinkable. But seawater contains a lot of salts and other nutrients that the human body needs is very good for the human body, so why can't seawater be drunk?
1. It is very uncomfortable after drinking seawater. Many people want to try to drink seawater when they are thirsty or when they are playing at the beach, but the taste of river water is very bad, and it tastes salty and bitter, because it contains magnesium ions and other metal ions, and people will feel very uncomfortable in their throat and tongue when drinking.
2. Seawater is very unhygienic. There are all kinds of small animals in the seawater, and in recent years, a lot of industrial wastewater and some garbage have been thrown into the ocean, the concentration of various substances in the ocean is more than the standard of drinking water, if a large amount of drinking water is to drink, it is likely to cause the human body to appear dehydrated diarrhea or even poisoning symptoms, will have an impact on the human body, affect the normal physiological function of the human body.
3. Salt is made of sodium chloride.
composition, in the human body of blood as well as tissue fluid.
Cells contain table salt. And under normal circumstances, the solution inside the cell and the plasma outside the cell need to maintain a certain concentration, but the salt content of seawater is very high, almost three times more than that of the human body, and if people drink seawater, the oxygen content in the body will also increase a lot. In order to achieve the same concentration inside and outside the cells, the water in the cells will seep out, resulting in a lack of water in the cells of the body, so the seawater cannot be drunk directly.
4. To be precise, seawater does not mean that many people who are shipwrecked at sea or drifting at sea have to use seawater to quench their thirst, so it is not that they can't drink at all, but the concentration of salt in seawater is about three times that of the human body, so the function of human kidneys to excrete salt is very limited, and the concentration of salt excreted by general salt will not exceed 2%, and the concentration of salt below seawater is about it, so drinking seawater not only can not play a role in hydration, it may lead to dehydration of the human body.
It can be seen that seawater is indeed not drinkable, especially many people like to go to the beach to play, at this time, we must pay attention not to drink seawater, and take a bath with fresh water in time after playing at the beach.

Anonymous users2024-02-08Everyone knows that there are many harmful things in seawater, although seawater is also water, but there is too much salt in seawater, and so much salt is unacceptable to the human body. According to scientists, we can know the reason: because in daily life, when eating, it is indispensable to eat vegetables, and to cook dishes to put salt, if you put too much salt, people will feel thirsty after eating.
People who drink seawater will feel thirsty and heavy, and will have mental disorders. If you drink 100 grams of seawater, your body will excrete 150 grams of fresh water, so if you don't drink water, you will be thirsty even more. According to scientists, people who die at sea are 30% less likely to live than those who don't, so they can't drink seawater.
However, if you are stranded on an island with no fresh water but only seawater, and you are really thirsty, you can use distillation to turn seawater into fresh water. First make a fire, scoop some seawater with an iron bowl (if you don't have one, you can use shells), then use a rack to put the bowl on top, then use a pipe (if you don't have one, you can use a hollow wooden stick) to put it in the bowl (the other end is released), and then use another bowl to connect under the other end and wait for the water to flow out of the tube.

Although first love is rarely successful, there are also successes!! If you don't try, you'll regret it later. I advise you to try it no matter what the result is, or you will succeed.
Because love is a joy between two lovers, but often do not think of reality, such as distance and other issues, resulting in lovers can not go together, if one party does not pay true feelings, it will not become a reality. In reality, the Internet is also a tool for acquaintance and a platform for heart-to-heart communication, so it acts as a platform for online love"Matchmaker", but first of all, the other party and themselves are sincere, but they can become a reality but the probability is particularly small, so it is best not to have online dating. To correctly understand yourself and reality, you often have feelings and can't get together for special reasons, reality plus sincerity is the success rate of online dating, the most important thing is the sincerity of both parties, otherwise the injury can only be yourself.
It's a very good life, although I've been imprisoned many times before, but this time I came out and became the boss of the company.
Everyone likes different people at different ages and in different environments, but there is always one that every time you think of him, what you remember is his goodness, and that is the person you love the most. >>>More
In the past few years, the MVP has only been Kobe and James, and it should be Wade, but I think it should be given to Nowitzki, after all, the home court, the commentary has also said, and there may be the same as when the Houston All-Star Game, everyone passed the ball for Maddie, hoping that he would win the MVP, but I didn't expect that James was not interested and took away the MVP, and this year is like this again, hehe, get used to it, in short, the current NBA is not good-looking, the predecessors have retired one after another, and few of the juniors can catch up, This year's All-Star is the largest number in history, but it is the most boring in history, the most interesting all-star game, the slam dunk contest, hehe, everyone should also watch it, Barkley said, no one won this dunk contest.
