8 Drinking Salt Water Benefits And Why Seawater Can Be DEADLY

Last Updated on December 7, 2020

Salt is an essential nutrient. Yes, you probably get everything you need in the food you eat. However, drinking saltwater has many benefits, which will be discussed at length in this article.

There are researchers and advocates claiming that salty drinks help to cleanse the stomach and colon while repairing the damage your diet has caused in the cells of your digestive tract.

But some of these claims should be taken with a pinch of salt (sorry, I couldn’t resist). This article will outline reasons why you may and may not want to drink more salt.

Specifically, the drinking salt water benefits you should really know about.

What Happens To Your Cells When You Drink Salt Water?

Normally, the saltiness of water in your cells is the same as the saltiness outside your cells. This is called an isotonic state. But when you drink water, a concentration difference takes place.

Water from the outside moves into your cells to maintain equilibrium or balance and this is known as osmoregulation.

But if you drink too much seawater the salinity outside your cells will increase rapidly.

This forces too many water molecules to move out of your cells so even if you’re already dehydrated, yourcells will release water rather than absorbing it. This is why drinking sea water is not only a bad idea but potentially fatal.

Hence, even if you’re already dehydrated your cells will release water rather than absorbing it so you will always feel dehydrated no matter how much you drink.

Why Can Seawater Be DEADLY?

Drinking seawater leads to a high sodium concentration outside your cells. And your cell needs to regain its for survival isotonic state. This is essential while your body tries to remove excess sodium from its extracellular fluids.

Salt is typically removed via your urine. However, the human kidneys (responsible for doing this) can only remove salt at the level that is lower than seawater.

The result is that you need to urinate more water than you initially consumed. This leads to dehydration because you can never drink enough seawater.

If you find yourself in this situation, then drink as much fresh normal water as you can.

However, drinking seawater is NOT the same as drinking salt water. This is because you can control the amount of salt you put in the water. Also, a small amount of natural healthy salt in warm water can be very good for you.

Seawater Vs. Saltwater FAQ

Drinking Sea Water To Survive?

No, you can not drink seawater to survive.

Human kidneys produces urine, which is less salty than saltwater. To get rid of the excess salt that is absorbed when drinking seawater, you need to urinate more water than you drink.

You will never stop feeling thirsty and eventually you will die of dehydration.

Why Can’t Humans Drink Salt Water For Hydration

By “seawater” we are talking about water that comes directly from the sea. So, let’s be clear, “drinking seawater for health” is not really possible because it does more harm than good.

If you’ve accidentally swallowed seawater, that’s no problem, especially if it’s a tiny amount. But seawater is neither good nor healthy for you. There are no “seawater benefits”.

Saltwater (i.e. fresh water mixed with natural salt) on the other hand, can be good for you as highlighted in this article.

Drinking Salt Water Benefits

Salt water works because the positive ions in the salt surround the negative ions of the water molecules. Water is no more water and salt is no more just salt. This results in a new structure that is easier for the body to absorb.

Please note that drinking SALT water is NOT the same thing as drinking SEA water, you should NEVER drink SEA water. On average, seawater has a salt content of about 3.5% and this is far higher than what your kidneys can cope with. Also, always consult your doctor before adding a lot of extra salt water to your diet.

Drinking a mixture of natural salt and water has many health benefits. It’s not new either. For centuries it has been used as a remedy all over the world. Both anecdotal and scientific evidence support its use for the following:

Green Plus ArrowSalt Water Is Good For Hydration

Yes, we should drink more water. While most people need to drink more water, it is possible to drink too much.

According to Matt Stone author of “Eat for Heat: The Metabolic Approach to Food and Drink”, consuming too much pure water can actually cause the body to become overly diluted.

When that happens, it can put a lot of pressure on the body and slow down the metabolism. Cell health depends on a certain concentration of minerals and electrolytes.

When we drink large quantities of water, the extracellular fluid is diluted, which responds to stress and the release of adrenaline.

AquaTruHave you ever watered a plant when it is extremely wet? The water just comes out of the bottom of the pot. Drinking water is constantly similar: we continue to pee and drink.

A little salt and natural water slows down this process and allows for better absorption.

Green Plus ArrowDrinking Salt Water is Good For Digestion

The salt water begins to activate the salivary glands in the mouth and release amylase. This first step in the digestive process is very important.

In the stomach, natural salt stimulates hydrochloric acid and a protein digestive enzyme that helps to break down food.

The role of unrefined natural salts in stimulating gastric acidity can not be minimized. The stomach is designed to secrete hydrochloric acid.

This kills pathogens such as harmful, fungi, bacteria and yeast. It also makes proteins more digestible. Therefore, people with low levels of stomach acid can not digest those proteins that can stay in the stomach causing gas, bloating, and food allergies.

When undigested food accumulates in an unhealthy stomach, acidity and reflux occur.

This is because the food stays in the stomach for so long that it begins to ferment (eww). It then produces gases, introduces new strains of potentially harmful yeast into the digestive tract, and produces secondary acids that contribute to heartburn.

When people start to suffer from these symptoms, their first step is usually to get antacids.

But as a study from 2008 shows, by increasing the pH of the stomach, antacids affect the digestive capacity of the stomach even more.

This leads to a greater reduction in protein digestion, increases the potential of food allergy and even exacerbates the situation.

The miracle of warm saltwater is that it helps to solve this problem of bad digestion by supporting the natural function of the stomach instead of impeding it.

Warm salt water also stimulates secretion in the digestive tract and in the liver. Regular consumption of brine may also contribute to regularity and increase nutrient uptake.

Green Plus ArrowSalt Water Can Mean Reduced Inflammation

The basic requirement of the human body for salt is 1.5 teaspoons or 8 grams per day. If we do not consume this essential amount of sodium, the body goes into a “crisis mode”.

This mode is called sodium saving so it can maintain fluid balance and blood pressure. This type of crisis is a critical survival mechanism. And it also has negative consequences.

With low salt intake, an enzyme called renin and a hormone called aldosterone increase rapidly. When this condition is prolonged, higher levels of renin and aldosterone cause circulatory damage and an increase in inflammatory levels in the body.

Researchers have linked a persistent salt deficiency to an increased risk of chronic diseases such as metabolic syndrome, cardiovascular disease and cognitive disorders.

Green Plus ArrowSalt Water Can Lead To Better Sleep

Salt, especially raw natural salt, reduces stress. Stress is perhaps the leading cause of sleep loss for most people.

Think of all those nights when you could not sleep, your thoughts raced and fluttered from one worry to the next.

The warm salt water can actually help with this problem. Research shows that natural salt has a unique effect on stress levels.

As an article published in the Journal of Neuroscience shows, increasing blood sodium levels can reduce the stress response. Salt helps to alleviate fears and reduces worry.

To sleep better, do not drink your salt water drink more than one hour before going to bed.

Green Plus ArrowDetox By Drinking Salt Water

Due to the rich minerals, salt water supports the body in its natural detoxification process. The salt water is also naturally antibacterial and can rid the body of dangerous bacteria.

As many people suffer from poor digestion, undigested food and waste accumulate in the gastrointestinal tract over time.

This residue can slowly ferment in the stomach, small intestine and colon, causing harmful bacteria and other pathogens to grow.

These pathogens produce their own toxins, which accumulate more and more in the digestive system.

The warm salt water can eliminate these wastes and toxins while cleansing the digestive tract and speeding up bowel movements. This forces all of this accumulated waste at once, so you are much less toxic than before!

Green Plus ArrowSalt Water Can Be Good For Bone Health

One popular theory about osteoporosis and other bone diseases is that the body uses calcium and other minerals from bones.

It uses them to survive and neutralize the acid in the blood. However, it is believed that salt water improves bone health because it is full of naturally healthy minerals and has an alkalizing effect.

And if you’ve heard rumors that salt intake actually causes osteoporosis, think again.

A study published in the Journal of Food and Chemical Toxicology concluded that “for the generally healthy person, there is no proven evidence that salt intake at the current average of 9 grams per day is a risk factor for osteoporosis.”

And that’s just for unpleasant and normal table salt. Considering how good the $unrefined natural salt is for your body, it’s fair to say that you do not have to worry!

Green Plus ArrowSalt Water Can Be Good For Skin Health

Natural salt contains minerals that can help your skin look and feel better. Chromium combats acne and reduces skin infections. Sulfur keeps the skin clean and soft.

It can also help a dry scalp, eczema and rashes that are often due to a lack of sulfur. Zinc promotes rapid wound healing, strengthens the immune system and regulates the activity of the sebaceous glands.

Iodine helps to increase the oxygen consumption and metabolic rate of the skin.

All of these mineral can be present in natural high quality sea salt (not table salt).

Green Plus ArrowAchieve Mineral Balance By Drinking Salt Water

According to Dr. Linus Pauling, two-time Nobel laureate, almost any disease, illness or ailment can be traced back to a lack of minerals.

Minerals are the foundation of sound nutrition and health. Without it, no other system in the body works as it should.

Amino acids and enzymes do not work without other vital minerals being present. Without this our vitamins and other nutrients are not broken down or absorbed.

Mineral deficiencies are more common than ever due to our depleted soils and our superfine diet.

Salt water, which consists of natural mineral-rich sea salt, is a good source of vital minerals. These include trace elements of chromium, barium, B2, bismuth, selenium, magnesium, zinc and titanium.Dashed Line

Are There Real Drinking Salt Water Benefits?

Yes. Seawater and saltwater are both salty water but that’s where the similarities end. We have always been told that it is harmful to consume a lot of salt.

Mr Water Geek ThinkingThis is true to a certain extent but it really depends on how much you consume, the type of salt you consume and how you consume it.

“A lot of salt” is bad for you. Seawater has a lot of salt and this is why it is bad for you.

However, a smaller amount of salt can be very good for you.

If you use the highest quality salt like Pink Himalayan or Celtic Grey Salt in fresh filtered water, the health benefits can be significant.

However, I strongly recommend that you consult a doctor before adding lots of extra salt to your diet. Especially as people differ in body type and may react to extra salt in very different ways.

  1. Hi,
    I’d like to comment on someone’s comment. You said your grandmother gave you some when you were sick, right? Sips of it you said. She probably knew the exact amount to give you. If a person drinks it regularly they have no idea how much salt they’re drinking.l because they didn’t put it in themselves.

    But salt water YOU control how much salt is put into it. So that I believe is a much safer option since the one controlling the amount of salt is YOU.

  2. Great article. Salt gets a bad reputation but you are helping to clarify the life sustaining properties of it. Could you possibly provide a ratio of salt to water and an amount that might be worth looking at. Presently I’m sipping on a half teaspoon of Celtic Sea Salt in about 500ml of warm water with a few drops of Lugol’s iodine and some cider vinegar. It tasty.

  3. Hi. I am about to experiment with sea water. I beg to differ on it being any more harmful than salt water. my grandmother, a Cornish lady used sea water as a cure for many different ailments and she saved my life with sips of sea water once. I agree that you cannot use it to replace ordinary water and it is not something to take when thirsty or deyhydrated. I say take rather than drink as it is more like a medicine than fluid replacement. It is free and according to my grandmother perfectly balanced for the human body as long as the person taking the sea water listen to their body when taking it and especially their sense of taste. It is actually very unpleasant to try to swallow more salt than you need. Salt water and sea water is pleasant when you need it. Your taste buds will tell you exactly how much you need. Sea water taken in sips as long as it tastes pleasant is good for you. It can especially help with issues such as constipation as the salt draws water into the digestive tract. It helps with weight loss due to fluid retention for the same reason. Sea water is also good to cleaning wounds, stomach upsets, acne, boils. There is no real difference between salt water and sea water other than sea water being free and unprocessed and a very powerful healer just by sitting and looking at it and hearing it roar. You can just as easily if not more easily OD on salt water as sea.

    1. Hi Mandyjane2

      Thank you for providing a different perspective!

      However, one issue with recommending people to drink sea water (especially directly from the sea) is not knowing the level of contamination, bacteria and viruses that you’re exposing yourself to.

      Another issue is that you can never really know the level of salt potency as well as the myriad of other nutrients, chemicals and minerals that will naturally occur in sea water.

      But I’m always open to change my mind on this especially if you have some academic research to back up some of your claims.

      Stay hydrated,

  4. Fantastic article!
    From my point of view, the best benefit of salt water is better sleep The minerals present in salt water help you relax and calm the entire nervous system. They also help in controlling the stress hormone, that promotes better sleep and allows your body to rest.
