Seawater as a path to health
There are numerous theories about the benefits of consuming seawater, ...
Every schoolchild has been taught that seawater is undrinkable because it causes dehydration. There have, however, been several cases where people were shipwrecked on desert islands and survived for months despite only having access to a few litres of fresh water. How could they do it? Simply put – they found that diluted seawater is not only completely harmless, but even beneficial. As the renowned medieval physician Paracelsus observed: “Anything can be a poison. It is the dose that makes it poisonous.”
Seawater is four times saltier than our body fluids, which leads to a disruption of osmosis. To avoid poisoning the human organism, there are certain rules to be followed when drinking it. We can consume it in two ways:
Seawater is a rich source of minerals and other healthy elements that provide all sorts of benefits for the human body. Please bear in mind that it cannot replace fresh water and it cannot be consumed according to the same rules.
Isotonic = 4× diluted seawater that has the same characteristics as the body’s internal environment and therefore places no stress on it. The recommended daily intake is 1 l of isotonic seawater, which can be made by mixing seawater and freshwater in a ratio of 1:3 (250 ml of seawater + 750 ml of fresh water). This is the recommended daily total and can be drunk in several portions.
Hypertonic = undiluted seawater, which can only be drunk in small doses. Its potential uses include cleansing the organism, rinsing the mouth or as a nasal spray.
You might ask: “Why should I drink seawater if I can just mix a couple of teaspoons of salt into tap water and be done?”
Cooking salt or common salt, NaCl (sodium chloride), can be found in nature in the form of a mineral known as halite. Cooking salt is a pure inorganic compound that does not offer such a wide range of benefits as seawater.
Why I don’t drink water with salt:
Mineral water or seawater? Which contains more beneficial substances? Which is better for the body? They both have a lot to offer, so judge for yourself.
The proper functioning of our bodies depends on a supply of nutrients from which they can extract the materials they need. From food and drink, the body extracts not just vitamins, enzymes and fatty acids, but also minerals, which are vital to many processes in the human body. If we are honest, we must admit that our food provides less of them than it did in our grandparents’ days, which is why many people are turning to nutritional supplements to top up on specific minerals. These include types of water with special contents.
Mineral water
Mineral water comes from natural underground sources that are rich in a variety of minerals. In Europe, it has long been synonymous with springs at spas. Their beneficial effects on the human body led to them being widely used at spas in baths, wraps or inhalations, but they can also be taken internally. The conditions mineral waters are used to treat depend on their chemical composition and physical properties. They help in the treatment of gout, kidney stones, skin problems, joint pain, diabetes and respiratory problems, amongst other diseases.
Seawater contains a wide range of substances in organic form, which makes them easier for the body to absorb and process. To achieve the desired effect, minerals should complement one another, preferably all at once, rather than in succession. In contrast to mineral water, seawater contains 78 minerals and trace elements, as well as several other beneficial substances. It thus contributes to the proper functioning of the human body.

Chart 1 shows that seawater is richer in positive ions (Mg, Ca, Na, K), trace elements and other enriching substances, and sulphate anions.
Consumption of seawater has been shown to improve cholesterol levels and help prevent cardiovascular disease. It reduces blood pressure, the quantity of fat and body weight. It can help in the treatment of diabetes, cataracts, stomach ulcers or skin problems, and it protects the liver. It has also been shown to have therapeutic potential in the prevention of cancer growth and the treatment of osteoporosis.
Do you feel tired, is it difficult to get up in the morning, or do you seem drained of energy? Seawater can also help with these problems.
Groundwater is at risk of pollution from human activities such as agriculture, industry or logging. The use of inappropriate fertilisers, pesticides and other chemical preparations can affect the health of people who rely on groundwater.
There is still plenty of seawater on earth that has been relatively unaffected by human activity and is safe for drinking after basic cleaning processes. If it is used in line with recommendations, it can help both to prevent illness and improve existing conditions.
Incorporating seawater into your diet is an easy way to boost your immunity. It has no chemical additives, but 78 minerals that will fight for your health.
You can use seawater in cooking, to rinse cavities and to drink – when diluted 1:3. A two-litre bottle can be used to prepare 8 litres for drinking and costs just CZK 31.10. You can order this cheap and natural source of health from the sea in our e-shop.
