What are the consequences if we drink a lot of seawater?

Water plays a very important role in our lives, it is the source of life, and it is one of the indispensable material resources for human survival. With the world's population.

The world's freshwater resources are due to the rapid increase in human over-exploitation and waste, as well as industrial pollution.

Humanity is also facing a serious water crisis, while the earth is rich in water resources and short of fresh water. But do you know why when you are shipwrecked at sea, you can't drink seawater even if you are thirsty, and what is the reason for this?

Anyone who swims at the beach knows that the sea water is salty and bitter, and that's because it contains a lot of salt, most of which is sodium chloride.

In addition to this, other ingredients are magnesium chloride.

Magnesium sulfate, iodine, potassium, sodium and other salts, because magnesium-containing substances are bitter, so the seawater will be salty and bitter, and the salt content in the seawater is too high, but also greatly exceeds the range of human physiology. According to the data, the concentration of salt in seawater is four times that of the human body, and the concentration of salt excreted by the human kidneys cannot be higher than 2% at most, but the concentration of salt in seawater is about!

If we drink seawater directly, it will immediately cause the cells to lose a lot of water. For example, the human body is like the pickled and salted radish in our life, if you put a fresh radish in a certain concentration of salt water, after a period of time, the white radish will become soft. Therefore, if I had not been shipwrecked and drifting on the sea, I would never have been able to drink seawater directly for emergency relief, because if we drank seawater directly, our body would immediately have serious dehydration symptoms.

Our body can't excrete so much salt, so the salt in our body accumulates more and more, and worse, we feel thirstier and thirstier, and we will sweat a lot. Experts have calculated that if we drink 200 ml of seawater, then if we want to drain the salt contained in the seawater, we need to discharge 350 ml of water from the body, so it does not quench thirst, and we will lose more water in the body, which is very dangerous!

The concentration of seawater is much higher than that of human body fluids and can cause severe dehydration, which can be remedied by quoting large amounts of fresh water. And seawater contains a lot of pollutants and bacteria that can cause human poisoning.

Seawater itself is salt water and cannot be directly drunk as fresh water. If we drink a lot of seawater, it will disrupt the balance of water and salt in the body, and we will actually feel more and more thirsty, which can be life-threatening if we do not replenish fresh water in time.

A large amount of seawater causes the water in the cells in the body to be absorbed by the seawater, which can lead to dehydration in humans due to osmosis.

The body can't stand the high salinity.

This is because the water that people ingest into their bodies every day passes through the kidneys and excretes it into urine or sweat. The kidneys have limited excretion function, and generally excrete no more than 2% of salt, while the salt content of seawater is as high.

If you drink seawater directly, it will not only overburden the urinary system, but also in order to discharge the salt brought in by every 100 grams of seawater, the human body needs to supplement an additional 75 grams of fresh water to dilute the seawater to 2%.

In this way, the human body has to excrete 175 grams of water. If a person drinks seawater and has not replenished fresh water, it can only consume the original water in the body.

The role of seawater

Salt from seawater.

China's sea salt production has developed rapidly, and 11 coastal provinces, autonomous regions, and municipalities directly under the central government have salt pans, and the area of salt pans has increased by a large margin compared with the early days of the founding of the People's Republic of China. The quality of the sea salt produced is also constantly improving, and the variety is increasing.

In addition to raw salt, washing salt, crushed washing salt, refined salt, iodized salt, table salt, casing salt, egg yolk salt and beach fine salt have been put into mass production, and seasoning salt, livestock salt bricks and so on are being put into trial production.

Seawater becomes fertilizer.

Potassium is the sixth largest source in seawater, with a total of 600 trillion tons. Potassium chloride is the fertilizer we extract from seawater. Potassium fertilizer is fast-working, easy to be absorbed by plants, and not easy to lose.

Potassium fertilizer can make crop stalks grow stronger, prevent lodging, promote flowering and fruiting, and enhance resistance to cold, diseases and pests.

Because seawater contains a large number of salts and a variety of elements, the concentration of various substances in seawater is too high, far exceeding the drinking water health standards, if a large amount of drinking, it will lead to excessive entry of some elements into the human body, affecting the normal physiological function of the human body, and serious poisoning.

Seawater is a very complex multi-component aqueous solution. All elements in seawater exist in certain physical and chemical forms. The presence of copper in seawater is more complex, and most of it is in the form of organic compounds.

Among the free ions, only a small fraction exists in the form of divalent positive ions, and most of them occur as negative ion complexes.

Seawater is the "home" of salt, and seawater contains various salts, about 90% of which are sodium chloride, that is, table salt. In addition, it also contains magnesium chloride, magnesium sulfate, magnesium carbonate and other salts containing potassium, iodine, sodium, bromine and other elements. Magnesium chloride is the main ingredient of the brine used for tofu, and the taste is bitter, so the seawater with a large proportion of salt is salty and bitter to drink.

In daily life, many people will have a question, whether it is fresh water or sea water, why can't people drink sea water directly?

In fact, the human body is unacceptable or the main reason is that the body can't stand the high salinity, because the water in the body that people ingest every day needs to pass through the kidneys to turn the water into urine or sweat and excrete it from the body. The excretion function of the kidneys is also limited, and the concentration of salt excreted by the general excretion should not exceed 2%, while the salt content in seawater is as high. If seawater is forcibly substituted for fresh water, due to the physiological structure of the human being, in order to achieve the concentration inside and outside the cell, the water in the same cell will seep out and cause the cell to lack water.

What are the consequences if the human body drinks seawater directly?

1. Dehydration of the human body. The concentration of salts in seawater is 4 times that of human fluids, and the ability of the human kidneys to excrete salt is very limited. During this period, it will lead to direct drinking of seawater, which will not only fail to quench thirst, but will even lead to a large loss of water in the body.

2. Cause poisoning. Seawater contains a large amount of salts and a variety of excess elements, and the concentration of these substances is too high, far exceeding the standard of normal drinking water. If only a small amount of seawater is drunk, it will not cause unnecessary harm to the human body, but drinking a large amount of it will cause some elements to enter the human body, thereby affecting the physiological functions of the human body, and in severe cases, it will also cause poisoning reactions.

3. Endangering physical health. The level of sanitation in the seawater is also not guaranteed, because the sewage, waste residue, waste oil and various chemicals generated by manufacturing and operations are constantly entering the sea. Therefore, the hygiene of seawater cannot be guaranteed, and drinking seawater is likely to have adverse effects on the body.

What should I do after drinking a lot of seawater?

If the human body unintentionally drinks a large amount of seawater, it should be remedied by drinking a large amount of fresh water, because a large amount of fresh water can dilute the excessive intake of minerals and other elements in the body, so that they can be excreted through sweat, urine and vomiting.

A man in a foreign country has done an experiment, he wanted to see if he could use traditional distillation to turn seawater into drinking water, and after pouring seawater into a pot, he saw a layer of impurities floating on the surface of the water.

After layers of filtration, as the water vapor evaporated, the color of the sea water in the pot became whiter and whiter, and the liquid in the pot boiled until it dried up, but there was still a lot of salt solidified at the bottom of the pot.

In the end, the sea water distilled to get a pot of salt at the bottom, so it is no wonder that they don't drink seawater, because the more they drink, the more thirsty they get.

Why the crew would rather die of thirst than drink seawater, it is chilling to learn the truth.

If you drink seawater, you can take a lot of fresh water to remedy, a large amount of fresh water can dilute the body's excessive intake of minerals and elements, and excrete them through sweat.

According to statistics, among those who died at sea, the mortality rate of those who drank seawater was 12 times higher than that of those who did not. It turns out that the human body has to excrete about 150 grams of water in order to expel 100 grams of salts contained in seawater, so people who drink seawater not only cannot replenish the water needed by the human body, but also accelerate dehydration, and finally cause death.

Why the crew would rather die of thirst than drink seawater, it is chilling to learn the truth.

Why the crew would rather die of thirst than drink seawater, it is chilling to learn the truth.

Seawater contains a large number of salts and a variety of elements, many of which are needed by the human body, but the concentration of various substances in seawater is too high, if a large amount of drinking, it will cause some elements to enter the human body in excess, affecting the normal physiological functions of the human body, and in serious cases, it will also cause poisoning.

The salt concentration of seawater is higher than that of our body fluids, and water molecules always diffuse from low concentrations to high concentrations (to put it simply, the osmotic pressure of seawater is relatively large, which draws the water out of our body), so drinking seawater not only does not replenish water, but accelerates the dehydration of the body.

Seawater is chemically complex and contains a lot of microorganisms, and drinking it is likely to cause diarrhea and worsen dehydration.

So don't drink seawater directly, but if you can, you can distill seawater to get fresh water and drink it. The specific method is to boil the seawater until it boils, and the water that flows down after the steam condenses is collected and turned into fresh water (the water droplets that condense on the lid of the pot when boiling the soup are distilled water), and you can drink it with confidence. This principle is that the water vaporizes and rises after high temperature distillation, while the salts and other impurities do not volatilize and remain in the bottom solution.

Everyone 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.

The reason why this turns seawater into light cement is that due to evaporation, half of the water vapor is evaporated, and the other half is from the tube to another bowl, and after some time, the water vapor becomes water droplets in the tube, which is fresh water. How does salt go? It turned out that the salt was turned into gas and floated away, and if the lid was closed, all the water vapor in the bowl came out into the pipe again, and the water would be even more.

Why can't you drink seawater even if you die of thirst, but you can drink salt water? Be sure to pay attention after reading it.

Why can't you drink seawater even if you die of thirst? After foreigners boil dry seawater, what is inside subverts common sense.

Two foreigners prepared a steamer, ready to use distillation to test the seawater, only to see a foreigner carry this bucket, go to the beach to pour a large amount of water back, and then open the furnace to pour seawater into the still, there are three layers of cooling device above the rectifier, the seawater can be heated and evaporated to flow into the collector.

The concentration of seawater is higher than the concentration of body fluids (blood, cell fluid, lymphatic fluid) and will absorb water from the body, that is, the salt content of seawater is too high, the human body does not need so much salt, it needs to urinate or sweat to excrete these salts, so it needs a lot of water, more than the water contained in seawater! It became that the more you drink, the thirstier you get!

Seawater contains a lot of salt, and for every 100ml of seawater you drink, you have to expel 150ml of water.

Third, seawater has also become a problem for many human environmentalists to consider. We human beings have such a huge amount of seawater reserves, but it cannot be turned into fresh water that we human beings can use, and now human beings are facing a water resource problem, which has become a crisis for the survival and development of our human beings, so how to deal with such a situation has become a problem that countries have been trying to explore.

Seawater is rich in sodium chloride, so seawater is salty, and it can't be drunk without refining, and drinking seawater directly is not equivalent to drinking salt, and if you drink too much salt, you will get sick if you drink too much blood and the cells in your body are unbalanced!

Because there are a lot of minerals and impurities in seawater, including the salt content in it, it is also very high. If we drink it directly, the body will not be able to accept it, and we may have diarrhea or poisoning.

Because the salinity of seawater is too high. If humans drink it directly, it will cause the cells in the body to become dehydrated instantly. It is very likely to be life-threatening.
