Sea salt contains vital minerals which help you stay hydrated. The nutritional wealth of sea salt includes minerals like sodium, potassium, calcium, magnesium, bromide, chloride, iron, copper, and zinc among other beneficial elements.
Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for preservation and flavour.
Sea salt is produced from the evaporation of seawater.
Salt is a necessity of life and was a mineral that was used since ancient times in many cultures as a seasoning, preservative and disinfectant. It was also a unit of exchange. Salt was used metaphorically to signify permanence, fidelity, loyalty, durability, value, and purification.
Balneotherapy (Latin: balneum "bath") is the treatment of disease by bathing, usually practiced at spas. Sea bathing was once thought to have curative or therapeutic value. It arose from the medieval practice of visiting spas for the beneficial effects of the waters. The practice of sea bathing dates back to the 17th century but became popular in the late 18th century.
Salt is involved in regulating the water content fluid balance of the body. The sodium ion itself is used for electrical signaling in the nervous system. Hyponatremia is usually caused by drinking too much water, with insufficient salt intake.
Salt is also great for skin exfoliation. Some bath salts such as phosphates have a detergent action that softens calloused skin and aids in exfoliation.
Some bath salts act as water softeners. Soap does not lather well with hard water and can leave a sticky feeling. Soft water lathers better than hard water but feels slippery for a longer time during rinsing of soap, even though the soap is coming off faster, because the soap remains soluble.
High concentrations of salts increase the density of the water and increase buoyancy, which makes the body feel lighter in the bath. Very high concentrations of salts in water are used in many bath therapies. Researchers have also studied their use in treating arthritis.
