The use of the ocean and sea water for medical purposes, has a name. It is called thalassotherapy.
Most healing benefits of thalassotherapy, can be contributed to the minerals that are present within the ocean water. Sodium, chloride, sulphate, magnesium and calcium, to name the biggest.
These minerals are electrolytes, meaning that they conduct electricity when mixed with water. In the human body, they are important for nerve and muscle function, as well for hydration, acidity and pressure.
But that not all. These minerals/electrolytes, give antiseptic and antibiotic properties to salty ocean water. This means that they weaken, slow and even kill bacteria and some types of fungi, parasites and other microorganisms.
In addition, the minerals in sea water have anti-inflammatory properties too. Meaning they help reduce swelling, redness and heat in inflamed areas that the body is trying to heal.
Mineral rich water can be so soothing for unpleasant skin conditions such as eczema, psoriasis and acne.
Sea salt will help with inflammation from the skin and kill of harmful bacteria that would worsen the condition of an already vulnerable skin barrier.
Some minerals, like magnesium, helps hydrating the skin and protecting it from external damage.
Not only the skin benefits from contact with mineral rich sea water. Salt water will penetrate deep into the skin, through the process of osmosis. There it will help sooth joint and nerve inflamation.
Minerals like magnesium will help to relax strained muscles by repairing the calcium/magnesium ratio in the body. This will contribute further to better sleep a soothed, easy digestion and a relaxed mind.
