The healing properties of magnetic fields have been recognized since ancient times; in modern medicine, it is referred to as magnetotherapy. The beaches of Black Sea resorts are known for their special low-intensity magnetic fields, and the black magnetic sand contains a high concentration of magnetite. Exposure to these magnetic fields enhances metabolism in skin cells and accelerates the absorption of iodine and magnesium, which positively affects the central nervous system. This can alleviate fatigue, improve thyroid function, and promote better cellular regeneration.
