Salt has four different properties
1) Chemical properties
One of the chemical properties of salt is its antiseptic properties and removes contaminants. For this purpose, salt is used in various industries such as pesticides, disinfectants and detergents. The salts used for this purpose are generally industrial salts. This property of salt is also used in the treatment of diseases such as fungal infections of the skin and also the improvement of respiratory infectious diseases. Of course, the use of salt in salt therapy especially requires salt equipment (such as salt ponds, salt aerosol generators, salt masks, dry tubs of warm salt powder, etc.)
2) Physical properties
Salt is humidity absorber and absorbs moisture quickly. In this regard, the density of salt resources is important. Because the denser the rock salt, the more resistant it is to moisture and the less moisture it will have. Therefore, denser blocks in salt structures will be much more resistant to moisture. This property of salt is also used in the treatment of diseases that are caused by increased moisture in certain parts of the body, such as arthritis (accumulation of water in the joints), hydrocephalus (accumulation of water around the brain) and … that salt can absorb moisture from the skin. Therefore, hot salt dry powder tubs are used for this purpose.
4) The inherent property of salt, which is called “Mezaj” in ancient Iranian medicine.
This is a topic of ancient Iranian medicine that salt is inherently very hot and dry and can cure frostbite of nerves, bones and joints. From the perspective of ancient Iranian medicine, some diseases such as MS. It is caused by freezing of the nerves or osteoarthritis due to frostbite in the joint areas. Salt can take the cold out of the depths of the body and improve the diseases caused by the cold.
As mentioned, in order for equipment and devices not to be corroded by salt, halo therapy requires special spaces that are made of salt; these spaces are called salt rooms. The walls and floors of these rooms are made of salt and all salt equipment is installed in these salt rooms. These rooms can be made of salt blocks or salt patina, each of which has its own beauty with lighting and is very eye-catching. As mentioned, these spaces have a very pleasant effect on humans due to the negative ions released from the surface of sodium chloride, and are generally used for relaxation and meditation.
Building salt structures requires special knowledge, expertise and skills. These structures generally have underfloor heating and the floor is filled with warm salt powder, which is very effective in relieving foot pain caused by cold. A garden of salt rubble is usually built around the floor of these salt rooms for people to walk on. This is very useful for relieving fatigue and calming the nerves; because the most ideal foot massage is walking on rubble, which puts pressure on the sole of the foot exactly as much as the body weight and is very effective for relaxation.
