Why drinking sea water will speed up hot thirst

Because when seawater enters the human body, not only can it not supply water to the body's tissues, but on the contrary, it also takes the water in the human body and excretes it with the urine, which means that the water in the body does not increase after drinking seawater, but decreases! The cause of this phenomenon is a phenomenon in the human body (including all animals)."Semi-permeable film"Something is at work. This film has special properties:

It allows water molecules to pass through, but it does not allow solute (e.g., salt) molecules dissolved in water to pass through. If a U-shaped tube is separated into two equal parts with this film, an equal volume of water and a salt-like solution similar to seawater are injected into each of the two side tubes. If the amount of water injected into the left and right side pipes is the same as the liquid level of the salt solution, it stands to reason that the two liquids are in equilibrium.

However, this is not the case. After a short period of time, the liquid level on the left and right sides stabilized at different heights. The level of the salt solution rises, but the level of the water falls.

It seems that the water has penetrated into the salt solution, which is called this phenomenon"Infiltration"。The pressure generated by the height difference between the two liquid levels at the final equilibrium is called"Osmotic pressure"。Why is osmolality generated?

Under the isolation of the semi-permeable membrane, the water on the left and right sides can penetrate into each other, but the solute salt on the right can not penetrate into the left, causing the partial pressure of the water in the right solution to be smaller than the pressure of the pure water on the left, so a pressure difference is generated, under the action of this pressure, the pure water on the left penetrates to the right, until the pressure of the water on the left is equal to the partial pressure of the water in the solution on the right, and then the two liquid levels form a height difference. Why can't drinking salty sea water quench your thirst? Because after drinking seawater, the salt in the urine in the body increases greatly, so that the pressure of water in the human tissue is much greater than the partial pressure of the water in the urine.

Therefore, the more seawater you drink, the more water your body loses.

Seawater is salty, the concentration of cytoplasm in the human body is lower than that of seawater, and it is easy to lose water after drinking, so it will be more thirsty.

Because the concentration of cytoplasm in the human body is lower than that of seawater, it is easy to lose water after drinking, so it is more thirsty

The sea is full of salt. You think you usually put too much salt in your meals. Will.. Drink plenty of water. A truth.

There is a lot of salt in seawater, and salt has the function of locking in water.

Is the sea salty, like if you drink salt water, are you thirsty?

People can't drink seawater directly when they are thirsty, in addition to some minerals and salts, there are many impurities in seawater, which may cause bacterial infections and cause some adverse reactions.

Seawater cannot be drunk directly, and if you drink it directly when you are thirsty, it is likely to cause electrolyte imbalances and even poisoning.

This is because there is a lot of salt in seawater, which may cause our osmotic pressure to be different inside and out, resulting in dehydration.

Because boiling water is relatively easy to be absorbed by the human body, people need a lot of water when they are very short of water.

Hot water, usually refers to the temperature of the water. The difference between the functions of hot and cold water, the definition and explanation of water heaters, the definition and interpretation of the words "hot water", the explanation of the words (source, examples, etc.), the explanation of terms in the pharmacopoeia, the benefits of washing the face with hot water, etc.

Introduction

Data shows that hot water is 5 times more effective than cold water for washing and sterilization, which is not only comfortable, but also ensures health.

In the survey, we found that households believe that they need to add hot water to their lives, and 60% of consumers agree that hot water is five times healthier than cold water, and 60% of consumers believe that hot water should be extended to household chores such as laundry and cooking.

Popular Science: Why can't you drink seawater no matter how thirsty you are? Once the seawater has been evaporated, you can see it when you look at it!

First of all, I will introduce a biological knowledge: the phenomenon of water exchange between plasma and red blood cells, and between tissue fluid and cells in the human body is called osmosis phenomenon. There is a law in the phenomenon of osmosis, if two kinds of brine with different concentrations are separated by a semi-permeable membrane, the water molecules will always penetrate from one side of the dilute brine to the concentrated brine until the concentration of the two sides is equal.

Knowing the above principle, it is natural to understand that seawater cannot be drunk: the tissue fluid and cells of the human body contain table salt, which is sodium chloride. Under normal circumstances, the intracellular solution and the extracellular plasma must maintain a certain concentration, and the salt content in seawater is usually more than three times that of the human fluid.

In order to achieve an equal concentration inside and outside the cell, water will seep out of the cell, causing the cell to be dehydrated. So seawater is not drinkable.

There are many things in seawater that are harmful to the human body, 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.

Of course, the desalinated seawater is still drinkable.

Why can't you drink seawater? Do you really get thirstier the more you drink?

Because people are selfish and greedy, if you give him money, he wants power, and if you give him power, he wants to dominate the whole world, but it is precisely because of these desires that people will climb higher and higher, and they will have ideals and motivation.

Have you ever drunk it? It's really hard to drink... Theoretically, it is dehydrated if there is too much salt. The real situation. It's that you don't want to drink it when you take a sip...

Because seawater is very salty, drinking seawater will make people thirstier. The average salinity of seawater is slightly higher in the open sea, 35-36%, and slightly lower in the offshore, especially at the estuary inlet, at about 30%. Because of the fresh water entering the sea.

Drinking seawater is like eating pickles, how can you not be thirsty?

Seawater is highly salinity and is a highly concentrated liquid for human cells, because water has the characteristics of high to low concentration. The water in the cells of the human body will flow out of the seawater that the cells dilute and drink, and the less water in the cells, the thirstier they will be.

The water I usually drink is freshwater, and the sea water is salty.

Drink seawater when thirsty because of the osmotic pressure in the human body.

It is less than the osmotic pressure of seawater, so the osmotic pressure in the human body increases, antidiuretic hormone.

increase, so there will be a feeling of thirst.

The usual drinking water for people is freshwater. The total amount of water on the earth is 1.4 billion cubic kilometers, there is a lot of water on the earth, and the reserves of fresh water only account for the total amount of water in the world, and some of them belong to solid glaciers, which are distributed in the high mountains and the north and south poles that are difficult to use, and some fresh water is buried deep underground, which is difficult to exploit. The only water that can be used directly by humans is groundwater, lake freshwater and riverbed water, which together account for about the total amount of water on earth.

Humanity on freshwater resources.

The amount of water that cannot be extracted by humans is only about about the total amount of water on the planet, excluding the deep groundwater that cannot be extracted. Human freshwater consumption already accounts for 54 per cent of the world's available freshwater consumption, and freshwater accounts for less than 1 per cent of the world's total water supply. However, the problem of freshwater pollution has not been completely eliminated.

Therefore, the protection of water quality and the rational use of freshwater resources have become major issues of general concern to mankind today.

Because when you are thirsty, the proportion of salt and water in the human body is too large, and the proportion of salt and water in seawater is even larger, so you feel more thirsty after drinking.

Why can't you drink seawater? Do you really get thirstier the more you drink?

Do not drink seawater, the concentration of seawater is too high, it will cause the body to lose water. Moreover, seawater is not only composed of sodium chloride solution, but also contains many other elements.

Definitely not drink, seawater not only contains salt, but also a lot of heavy metal toxic substances, and there are a lot of marine plankton, a small amount will have diarrhea, fever, a large amount of poisoning will be fatal, there is a tongue licking can be, salty and bitter taste.

Seawater is not drinkable, and the tap water we usually have at home is freshwater, and there are many ingredients in it, and it can be poisonous.

No, it will speed up the dehydration of the body.

Not drinkable, seawater contains salt

You can't drink it, because the more you drink it, the thirstier you get.

Sea water is not drinkable, salty, does not quench thirst.

The sea water is salty, and the more you drink, the thirstier you get.

You can't drink it without quenching your thirst, and if you drink it, you will be even thirstier.

I can't solve the mouth, so drinking a small amount shouldn't be a big problem.

What is your impression when it comes to the sea? Is it endless or vast? The sea is endless, humans are both familiar and unfamiliar with it, you may have seen the sea but you don't necessarily know about it.

Most people know that seawater is salty, and the sea can extract salt, but there is a saying that "you can't drink seawater even if you die of thirst", this statement is well-founded, when you see this experiment done by foreigners, you can understand the truth of this sentence.

Two foreigners once did such an experiment with seawater, which was to take a bucket of seawater and boil it to see what would become of it in the end. They did this experiment with a distillation device of their own invention, then heated it on a stove at home and waited for the sea water to change. In this process, in order to make the experiment process faster, they chose to add some cold water to speed up the distillation, and before the water was boiled and dried, they first used a cup to receive the distilled water to taste, and found that the distilled seawater was not much different in taste from ordinary water.

The experiment continued, and in order to see for themselves what would become of the seawater when it was evaporated, they patiently waited for the water to boil dry. After the water was boiled dry, they clearly saw that at the bottom of the pot there was a layer of white salt, which looked no different from ordinary salt in appearance, but it was not edible, because the composition of this salt was sulfate, which was harmful to the human body. So, when you see this, you will understand that seawater cannot be drunk because it is rich in harmful sulfate components, and drinking it not only does not quench your thirst, but also makes you lose water in your body, which is counterproductive.

So is seawater worthless? Of course not. Sea salt can be extracted from seawater, of course, this sea salt naturally has no harmful ingredients, and it is also rich in many minerals that are good for the body, and many salts in coastal places are extracted from seawater.

Seawater is not drinkable, it contains salt, which will make you thirstier the more you drink, and there will be a lot of parasites in seawater.

You can't drink it, there is a lot of salt in the sea, and if you drink it when you are thirsty, you will get thirstier and thirstier.

No. If the salt is too high, you will only get thirstier the more you drink. The salt content of seawater is too high, and drinking it will cause dehydration; And there are many microorganisms and toxic substances in the seawater.
