Why is the water in the sea salty? There is so much water on the Earth's surface that it is often called the "blue planet." Land occupies only 29% of the Earth's area, and the remaining 70% falls on the mysterious and almost unexplored oceans. Obviously, such a quantity of water cannot have an absolutely identical composition, as can be seen from the example of the different saturation of salts in rivers and seas. But how to explain these differences?
Water is famous for its ability to erode any type of rock. It doesn’t matter what sharpens the stone - a powerful stream or a separate drop - the result is always predictable. During the destruction of the rock, it removes easily soluble components from it. Salts, which are also leached from the stone, give the water its characteristic taste.
Scientists have not been able to come to a consensus as to why some bodies of water have fresh water and others have salt water. To date, two complementary theories have been formulated.
First theory
The first theory is based on the fact that fresh water is just as salty as sea water, but the concentration of salt in it is seventy times lower. Salt-free water can only be obtained from laboratory conditions using the distillation method, while natural liquids have never been and will never be purified from chemical components and microorganisms.
All impurities that dissolve and are then washed away by water from rivers and streams inevitably end up in the waters of the World Ocean. Then the water evaporates from its surface and turns into, and the salt becomes part of its chemical composition. This cycle has been continuously repeated for two billion years, so it is not surprising that during this time the World Ocean has become so rich in salts.
Proponents of this theory cite salt lakes that have no drainage as evidence. If the water did not initially contain a sufficient amount of sodium chloride, they would be fresh.
Sea water has one unique property: it contains almost all existing chemical elements, including magnesium, calcium, sulfur, nickel, bromine, uranium, gold and silver. Their total number is close to sixty. However, the highest level is due to sodium chloride, also known as table salt, which is responsible for the taste of sea water.
And exactly chemical composition water became a stumbling block to this hypothesis. According to research, sea water contains a high percentage of hydrochloric acid salts, while river water contains carbonic acid salts. The question of the reason for such differences still remains open.
Second theory
The second point of view is based on the assumption of the volcanic nature of ocean salts. Scientists believe that the process of formation of the earth's crust was accompanied by increased volcanic activity, as a result of which gases saturated with fluorine, boron and chlorine vapors were transformed into acid rain. From this we can conclude that the first seas on Earth contained a huge percentage of acid.
Under such conditions, living organisms could not originate, but subsequently the acidity of ocean water decreased significantly, and it happened like this: acidic water washed out alkalis from basalt or granite, which were then transformed into salts that neutralized ocean water.
Over time, volcanic activity weakened significantly, and the atmosphere began to gradually clear itself of gases. The composition of sea water also stopped changing and reached a stable state five hundred million years ago.
However, even today the salinity of the water is controlled by a large number of underwater volcanoes. When they begin to erupt, the minerals in the lava mix with the water, raising the overall salt level. But, despite the fact that a new portion of various salts enters the World Ocean every day, its own salinity remains unchanged.
Returning to the question of carbonates disappearing from fresh water when it enters the sea, it is worth adding that these chemicals are actively used by marine organisms to form shells and skeletons.
Everyone knows that sea water is very harmful and tastes unpleasant. However, many adhere to the erroneous ideas that it can easily replace fresh water in conditions of extreme necessity. Such misconceptions can not only harm a person who finds himself in an extreme situation, but also cost him his life.
The thing is that the load associated with filtering any liquid entering the body falls entirely on the kidneys. Their task is to remove excess fluid through urine and sweat. In the case of sea water, the kidneys will have to process a large amount of salts, which can be retained, forming stones and impairing the functioning of the entire body.
Thanks to the kidneys, during the day a person excretes about fifty percent of the liquid he drinks during this period. Instead, excess sodium, calcium and potassium salts leave the body with urine. Sea water is so saturated with salt that the kidneys wear out very quickly, trying to cope with the work that is too much for them. One liter of sea water contains thirty-five grams of salt, which is several times higher than its content in human water.
The daily norm of liquid an adult drinks includes not only water, but also moisture received during meals. Every day, from fifteen to thirty-five grams of salt deposits in the body, which the kidneys successfully remove.
Thus, it turns out that in order to get rid of thirty-five grams of salt that entered the body along with a liter of sea water, it will have to produce one and a half liters of its own fluid, taking into account the fact that the amount of water drunk will clearly not be enough for this. To fulfill their task, the kidneys will begin to work to the limit of their capabilities and very quickly fail.
In addition, a lack of fluid coupled with a critical level of salt in the body will lead to severe dehydration, and after a few days the kidneys will stop functioning. Excess salt will cause damage to internal organs, the first of which will be the kidneys and gastrointestinal tract. Due to lack of moisture in nervous system irreversible changes will also occur.
In addition, dehydration in the process of quenching thirst with sea water is caused by the presence of magnesium sulfate in its composition, which has a laxative effect. As a result, dehydration occurs much more rapidly than usual, and the person quickly loses strength and ability to fight for survival.
The body can no longer produce its own fluid and cope with high level salt. In addition, sea water contains other dangerous substances, on the absorption of which the body will spend its last resources.
However, it is still possible to survive in the absence of fresh water. Some scientists and survival experts advise squeezing the liquid out of fish, no matter how strange it may sound. There are several documented cases where people managed to escape with the help of such fish “juice”.
Thus, the salt contained in the waters of the World Ocean can bring people both the sensation of flight from swaying on the surface of the sea, and become their worst enemy, gradually depriving them of the ocean that is contained in the body of each of us.
Often, sailors of ships that were wrecked or lost in sea waters died of thirst. But few people know why this is so, because there is a lot of water around.
The thing is that sea water is saturated with such a composition that it is not suitable for human body and does not quench your thirst. In addition, sea water has a specific taste, bitter and salty, and is not suitable for drinking. This is all due to the salts dissolved in it. Let's figure out how they got there.
What gives water its salty taste?
Salt has a crystalline appearance. Ocean waters contain almost all elements of the periodic table. Hydrogen and oxygen combine to form water molecules. It also contains impurities of fluorine, iodine, calcium, sulfur and bromine. The mineral base of sea water is dominated by chlorine and sodium (ordinary salt). This is why the water in the sea is salty. It remains to be seen how the salts get into this water.
How sea water was formed
Scientists have been conducting experiments for a long time and trying to figure out why sea water is salty and river water is fresh. There are several theories about the formation of salty sea water.
It turns out that rivers and lakes also have salty water. But the salt content in them is so small that it is almost unnoticeable. According to the first theory, river waters entering the seas and oceans evaporate, but salts and minerals remain. Because of this, their concentration increases all the time and the water in the sea and ocean becomes salty.
Interesting:
How has the Earth's surface changed?
According to scientists, the process of salinization of the seas has been going on for a billion years. But contrary to the first theory, it has been proven that the waters in the world's oceans have not changed their chemical composition for a long time. And those elements that come with river water only maintain the oceanic composition, but do not change it in any way. This leads to another theory. Salt has a crystalline consistency. Waves hitting the shore wash the stones. Lures form in them. When the water evaporates, salt crystals remain in these holes. When the rock breaks down, the salt gets back into the water and it becomes salty.
Consequence of volcanic activity
Scientists have concluded that the water in the seas was salty back in the days when humanity did not exist on the planet. And the reason for this was volcanoes. The earth's crust was formed over many years by the emission of magma. And volcanic gases contain chemical combinations of chlorine, fluorine and bromine. They entered the ocean waters in the form of acid rain, and initially the water in the ocean was acidic. This water broke up the crystalline rocks of the earth's crust, and extracted magnesium, potassium and calcium. These acids began to form salts as a result of reaction with hard earth rocks. Few people know that the salt we are used to is formed as a result of the reaction of perchloric acid from the ocean and sodium ions from volcanic rocks.
Thus, sea water gradually became less acidic and more salty. But by now, the sour taste has completely disappeared and we only see salty sea water. Supporters of this theory are confident that the water of the seas and oceans acquired its modern properties 500,000,000 years ago. It was then that the Earth was freed from volcanic gases and the composition of water stabilized. And the carbonates that penetrate into the seas with river currents disappear from the composition of the water thanks to the inhabitants of the underwater world, who filter and purify the waters. They use these minerals to build shells that protect the body from mechanical stress.
I was surprised when a friend told me that he starts his day with a glass of warm salt water every morning. It's not something I've ever heard of and it would be pretty disgusting to be honest. Find out in the article what salt water is and what benefits it brings to the body.
However, he was quite convinced of the health benefits, so I decided to look a little deeper into the matter. I like to keep it on track until I learn the science behind them. I am often pleasantly surprised by the amount of solid evidence supporting natural remedies.
I was skeptical about making salt water a regular habit because of sodium's well-known effect on blood pressure and heart health. Read on to find out if there are any health benefits to drinking salt water in the morning.
What's the deal with the salt drink?
Almost all websites discussing the health benefits of drinking salt water in the morning refer to the drink as "sole", pronounced "so-lay". This name appears to be derived from the word "sol", the Latin word for "sun".
From this exotic sounding name, I assumed that this drink has some kind of historical traditional use (some blogs mention India). But I couldn't find anything about the origins of the word or who uses it other than alternative practitioners and people selling expensive salts. If it's a Latin word, it's unlikely it would have originated in India, right?
I'm open to correction, but I believe this term was recently coined. There is nothing wrong. Because no one directly said that this remedy is thousands of years old. However, this made me suspicious from the start.
Drinking salt for “detoxification”
The health requirements associated with salt water vary greatly. If you believed everything you read, it's pretty much a cure. However, you need to take these claims with a grain of salt, so to speak.
As soon as I see the word “detox,” my mouse pointer starts to gravitate toward the little red “x” in the corner of the screen. And this word is common in information about salt water. Salt water appears to cleanse your system by drawing toxins out of your organs.
This is all very well, but unfortunately, “detoxing” is not a real thing. It's just a meaningless buzzword with no scientific backing. You have two very efficient systems“detoxification” in your body, cleansing all 5 liters of our blood, 24 hours a day, 365 days a year. These are called your liver and kidneys.
Your liver and kidneys don't need any help removing toxins from your system. In fact, even if you wanted to help, it would be impossible. If one of these was vital important organisms really distorted, you would have known about it. At this point, the home Detox program will not help you - you will end up in the hospital.
Does salt water lower blood pressure?
A rather strange claim that I have read on many sites is that "sole" can lower your blood pressure. The effects of salt on blood pressure are extremely well documented. If you've taken basic biology class, you'll understand why salt increases your blood pressure, and quite dramatically. If you want to know more details, you can read more here.
Too much salt leads to hypertension, stroke and heart attacks, among other diseases. That's why the American Heart Association recommends limiting your sodium intake to no more than 1,500 milligrams per day.
Apparently the reason the "sole" is so different is because you're making it with unrefined salt (think salts like pink Himalayan or European sea salt) rather than regular table salt. I'm going to talk more about this next, but there is almost no difference in sodium content between refined and unrefined salt. They're all equally dangerous for heart health—and that's not just my opinion, that's the official line from the AHA.
Some sources claim that the extra minerals in unrefined salt counteract the effects of sodium on blood pressure. Unrefined salt has many minerals, but they are tiny, trace amounts. I don't believe there are enough of them to have any significant impact on health.
What is the "unrefined salt" deal?
As I mentioned above, most "sole" enthusiasts feel strongly about using unrefined salt rather than table salt. While both are comparable in sodium content, there are some big differences in composition and preparation.
Most table salt or refined salt is collected from salt mines as a highly concentrated solution of water and salt known as brine. This brine is often treated with chemicals to remove mineral “impurities.” The salt is then separated from the water by evaporation. Other chemicals, for example, can be added to improve flow, prevent thickening and stabilize the salt.
Unrefined salt comes from the sea or individual salt mines. No minerals are removed and no chemicals are added. Some minerals found in unrefined salt include calcium, potassium, phosphorus, sulfur, titanium, magnesium and iron. Some sea salts can be specified, so you'll need to check the label to see if it's actually not specified.
Salt water and adrenal fatigue
Many websites claim that drinking salt water helps treat adrenal fatigue, which is the feeling of tiredness resulting from decreased adrenal gland function. Your adrenal glands like to increase your blood pressure in the morning - it's just a part of our body, a natural rhythm.
Apparently using salt water to raise your blood pressure, first of all in the morning (they now admit that it increases blood pressure!) takes the pressure off your adrenal glands. This means they can perform better throughout the rest of the day.
Apparently, after a few days of drinking the sole, your symptoms of adrenal fatigue will disappear and your energy will be higher than normal. Sounds good, huh? Well, it would be, except that adrenal fatigue isn't a real medical condition. There is no scientific evidence to support its existence.
Adrenal insufficiency is a real disease, but it is caused by damage to your glands and should be treated with hormone replacement—not salt water.
Many serious diseases occur in the human body due to the presence of toxins and wastes in it. Cleansing the body with salt water from harmful substances is necessary for those who have problems with the liver and intestines, because the full functioning of other systems depends largely on these organs.
The simplest and cheapest way to cleanse is to cleanse the body with salt water. To perform this procedure, you will need salt (preferably sea salt), as well as boiled and filtered water.
When salt water enters the body, moisture begins to be drawn onto it from the intestinal walls. Slags and fossilized feces are exfoliated with the liquid.
By removing them from the intestine, its walls are cleansed and absorption function improves.
In general, the procedure gives the following results:
- improves well-being and complexion;
- immunity is strengthened;
- digestion improves;
- various types of allergic reactions disappear;
- weight gradually normalizes.
Of course, you shouldn't expect good results right away. In order to feel the effective effect of the procedures, you need to perform them regularly and know exactly how to drink salt water. To simply feel better, one procedure per month is enough. But complete cleaning can be done only after 3-5 procedures, and they must be performed every other day.
Preparation and carrying out the procedure
In order for the cleansing procedure to be of high quality, it is necessary to properly prepare salt water. The salinity of the solution used should be as close as possible to sea water.
To do this, you need to dissolve two tablespoons of salt in two liters of water. The solution must be heated to approximately 40 degrees. When carrying out the procedure for the first time, you need to try it and decide whether you can drink salt water of this concentration. If it seems too salty and even causes a gag reflex, adding a small amount of water is allowed.
How is cleansing carried out?
The best time of day to do cleansing is morning.
First, on an empty stomach, you need to drink one glass of saline solution, and then perform simple physical exercises.
Then again after drinking a glass of water you need to do the same exercises. This must be repeated until 6 glasses of salt water have been drunk.
This is usually enough to empty the intestines. After getting rid of feces, you need to drink a glass of water again and do exercises. After visiting the toilet, you need to repeat everything from the beginning again: water, exercise, toilet.
You need to continue until it starts to come out pure water. Usually, 10-12 glasses are enough to cleanse the body. It is not advisable to drink more than 2.5 liters.
Complete the procedure this way:
- Drink 3-5 glasses of warm water without salt.
- To empty the stomach, they induce vomiting, and it also clears itself.
- After half an hour, eat a small portion of rice boiled in water (without adding oil).
On the day of cleansing, it is advisable not to make sudden movements and refrain from physical activity.
A set of exercises for cleansing the body with saline solution
- Having joined your hands above your head in a standing position, take turns bending left and right.
- While standing, you need to straighten your arms in front of you, and then touch your right collarbone with your left hand and turn to the right, while moving your right arm as far as possible. The same action must be performed in the other direction.
- You need to lie on your stomach and rest your forearms and toes on the floor. In this case, the distance between the feet should be approximately 30 cm. Next, you need to rise on your hands and turn your head and upper body, trying to see the opposite heel. The movement must also be performed in the other direction.
- Squatting, you need to spread your knees 30 cm and put your hands on them. Turning your torso to the left, you need to lower your right knee. The same must be done in the other direction.
Who is contraindicated for colon cleansing?
Cleansing the intestines with water and salt does not wash out the microflora from it, but it does an excellent job of removing fecal stones and many harmful substances. This is a fairly common method, because it does not require an enema, which can cause all sorts of damage. Moreover, salt water cleanses gastrointestinal tract completely, while an enema cleans only the rectum.
Drinking salt water for cleansing is not recommended if you have the following diseases:
- bowel cancer;
- stomach ulcer and colitis;
- diarrhea;
- stomach ulcer;
- appendicitis.
If you cleanse your body regularly in this way, you can protect yourself from the appearance of fecal stones and mold. They interfere with the normal functioning of the intestines and cause harm to the entire human body.
Shank-prakshalana. My experience: Video
The desire to lose weight, relieve swelling, and get rid of waste and toxins begins with. The accumulation of harmful substances contributes to a decrease in the quality of digestion and the occurrence of biochemical processes in the body.
A particularly popular method for cleaning the intestines at home is cleaning with salt water. Procedures carried out independently reveal indications and contraindications.
There are two methods: the method of Indian yogis (drinking a solution) and an enema (according to Malakhov). The result will be approximately the same. Before carrying out the procedures, it is recommended to consult a specialist.
A little about cleansing
An alternative medicine method is to cleanse the intestines with sea salt dissolved in water.
Analyzing the Indian method and the method of cleansing using an enema, promoted by Malakhov (due to the ambiguity of treatment methods), we come to the following conclusions:
- No one except the patient bears responsibility. Doctors simply will not advise unconventional methods of cleansing. Side effects and complications will appear.
- There is no guarantee of effectiveness. Officially, doctors claim natural self-cleansing of the intestines.
Signs of the presence of waste and toxins, their effects on the body, can manifest themselves negatively on well-being. Recommendations are made that allow or prohibit the use of a certain cleansing method.
Indications
Symptoms appear to varying degrees in everyone, especially in urban areas. A consequence of a sedentary lifestyle, bad habits, improper and untimely nutrition.
- Deterioration of the gastrointestinal tract (decreased functionality of the stomach and intestines).
- Bloating.
- Increased risk of ARVI, FLU.
- Development of migraine.
- Manifestation of rash, irritable skin reactions.
- Development of allergies.
- Weak condition, reduced performance.
- Excessive odor (body, oral cavity).
Contraindications
Cleansing results
Here are two ways to improve your gut balance: effective methods: enema and Shank Prakshalan (Indian yoga). Execution of methods using salt water is available at home. The result will not take long to arrive:
- Optimal functioning of the gastrointestinal tract.
- Normalization of microflora and metabolic processes.
- The gastrointestinal tract feels light (good digestion and cleansing).
- Immune protection increases.
- Weight loss.
- Cells are rejuvenated.
- Nutrition improves, insomnia and anxiety are eliminated.
- Allergy symptoms are eliminated.
If there is no result, an enema is used. Complications during the procedure are a consequence of drinking water contaminated with bacteria or poor quality salt.
How to cleanse the intestines?
Water and salt are not absorbed into the blood through the intestinal walls. In the process, the remains of undigested food are removed, creating a bactericidal effect. Sea salt is perfect for this procedure.
There are 2 methods suitable for cleansing the intestines: rectal - forced cleansing with an enema and salt water in combination with physical exercise.
Enema
Salty water
An effective and simple method requires strict adherence to the instructions of the Shank-Prakshalana technique. For cleansing, it is important to observe the proportions in preparing the saline solution; you can add lemon.
Preparing for cleaning. Before starting the procedure, you should not eat bread or meat, alcohol or carbonated drinks. Any manifestation of swelling is an indicator for cancellation. For a maximum of two days, it is permissible to consume only salads and fresh unleavened water-based cereals. Cleansing the body will be much better - improvement will come quickly.
Recipe of the product and application. Use water that has been filtered and boiled. Salt can be purchased at the pharmacy ( high quality). The procedure is carried out with a saline solution: 30 g per 1 liter of water. To cleanse the intestines you will need 2.5 liters. Water temperature 37C.
Drink the resulting product with lemon in the morning on an empty stomach, 300 g each. Next, carry out a series of physical exercises, alternating with each other.
Shank Prakshalana
You can cleanse your intestines by including a set of yoga exercises. Prevention is carried out once per season of the year. In the first stages, you will need a lot of free time to complete all the necessary exercises.
By correctly following a set of exercises, you will help the intestinal muscles relax and freely pass salt water.
Home recipe: the water should be sufficiently salted and warm, since the salt product can be absorbed into the blood in smaller quantities and filtered in the kidneys. Exceeding the amount of fluid will thin the blood, which will lead to a decrease in body temperature.
Normally, you will need to prepare 4 liters of drink at the rate of 15-25 g per liter of water.
Exercises
The execution time for each stage is ten seconds. Repeat 4 times. It is important to come to yoga classes prepared.
- Exercise No. 1. We start from a standing position, legs apart at a distance of 30 cm. Interlace your fingers together, palms should look up. Keep your back straight and monitor your breathing. We lean left and right. The stomach opens, allowing water to enter the intestines.
- Exercise No. 2. The position remains the same, and we support the right hand horizontally. Left hand bend so that the fingers barely touch the clavicle bone on the right. We make turns, keeping the waist motionless. Then we return to the original position. We also do left and right.
- Exercise No. 3. Cobra position: fingers should not reach the floor, but on the contrary, raise your hips. Keep the distance between your feet. The waist remains motionless.
- Exercise No. 4. At this stage, water passes through the large intestine. Contraindication: problems in the joints. We take a position - squatting, spreading our feet at the same distance. Your heels should be close to the outside of your thighs. Touch your own knees with your hands. We turn the torso so that one knee falls near the foot, opposite. We direct our hips towards the other side. We press on the abdominal area - salt water will help cleanse the large intestine.
Potential problems
The result may be unexpected. The purification process is disrupted for various reasons:
- If there is no bowel movement after several glasses, do an enema.
- Excessive gas formation - lie on your back, stretch out your arms.
- Manifestation of symptoms of nausea - we repeat the exercises 3 times, the situation does not change, we induce a gag reflex.
- Pain in the anus - use less toilet paper; after rinsing, apply Vaseline or vegetable oil.
What to do after the procedures?
After resting for an hour, it is important to eat boiled rice with a teaspoon butter. It is recommended to drink salty tomato-based juice. According to the advice of doctors, it is worth using products that restore the intestinal microflora.
The first time after cleansing, eat: wheat products, hard pasta, vegetable soups. You cannot eat dairy products, spicy foods (with pepper, seasonings), sour foods, raw foods (vegetables, fruits).
Oksana Viktorovna, 47 years old. I tried drinking a solution based on iodized salt, and it tasted much better. At first there was no effect, only after 4-6 hours the process began.
Tatyana, 26 years old. I liked it home recipe preparing a solution with the addition of lemon juice. The cleansing procedure is carried out without complications and quickly.
Cleansing the intestines with a solution with added salt will not allow water to penetrate the blood, completely directing the drug to rid the gastrointestinal tract of pollutants. The antiseptic effect of salt helps reduce the activity of harmful bacteria. Digestion is normalized.
