The salty water of the Dead Sea
The mineral content of the Dead Sea is significantly different from that of ocean water, consisting of approximately 53% magnesium chloride, 37% potassium chloride and 8% sodium chloride (salt) with the remainder comprised of various trace elements.
Comparison between the chemical composition of the Dead Sea to other lakes and oceans show that the salt concentration in the Dead Sea is 31.5%. Due to its unusually high concentration of salt, anyone can easily float in the Dead Sea because of natural buoyancy as a result of the higher density of the water.
The sea is called "dead" because its high salinity means no fish or macroscopic aquatic organisms can live in it, though minuscule quantities of bacteria and microbial fungi are present.
The minerals in the Dead Sea Salt
The concentration of sulfate, SO42-, ions is very low, and the bromide ion concentration is the highest of all waters on Earth. Chlorides neutralize most of the calcium ions in the Dead Sea and its surroundings. While in other seas sodium chloride is 97% of the salts, in the Dead Sea the quantity of NaCl is only 12-18%. In the following the four most important minerals are characterized:
Magnesium concentrations found in the Dead Sea are fifteen times higher than salts in other seas and are essential for cell metabolism. For instance, a significant deficit in Magnesium has been discovered in skin scales and serum of patients with psoriasis. Magnesium supposedly affects the ripening of skin cells of psoriasis patients. Moreover, in cases of bronchi, Magnesium works as anti-allergic agent.
Potassium is a basic element of the human body. It regulates the water balance of the skin, strengthens its defence mechanism and is anti-inflammatory.
Bromine is necessary for the production of the cyclic hormone AMP which regulates the regeneration of the skin and ensures the normalization of the skin's peeling process. It has an extreme soothing effect on the skin and the entire organism.
Calcium has an anti-allergic, itch-relieving effect and relieves the sensitive skin. It prevents infections and supports the skin balance.
