There is speculation that rock-salt lamps were used for the first time more than 6000 years ago. It is thought that they were found by chance when some water leaked into a large rock of salt, causing a weak light that revealed the shape of the chamber that was contained within the rock. However, many individuals are of the opinion that the first lights did not come from humans but rather had previously been there on their own for a significant amount of time before they were discovered. A hypothesis proposes that it has always occurred in this manner: salt attracts moisture, and over time, salty water evaporates on the walls of its surroundings until the conditions are such that a lamp is created.
Humans have used lamps for hundreds of thousands of years at this point. The oldest oil lamps ever discovered date back 7,000 years and were created using animal fat and tiny stones. In Ancient Egypt, lamps were crafted from various materials, including ceramics, stone, metal, and glass. Salt lamps were a common feature in almost all prehistoric societies, and they were crafted in a variety of ways.
Even today, lamps are frequently made out of rock salt because they have a high percentage of sodium chloride (NaCl), which, when heated, functions as an effective source of light.
They come with electric lighting inside the salt crystals or with a candle holder attached underneath them; some even have multiple levels inside each other for various purposes, such as aromatherapy compartmentalization. Rock-salt lamps are available in all shapes and sizes, and they can be made into almost any design imaginable.
In comparison to the overall history of salt lamps, the history of the traditional kind that has an internal light source is not very long at all. On the other hand, the Himalayan rock salt industry is credited with having been the first to come up with the concept of creating lamps that could either be lit by an internal bulb or by a candle. This likely occurred sometime in the 1990s. This resulted in a surge in sales, and not long after that, salt lamps gained significant popularity across the world, particularly in India.
They are known as natural generators of negative ions, and they cleanse the air by releasing infrared and ultraviolet light rays, which results in the production of ions known as “noctons.” In terms of electromagnetic hypersensitivity, these spectrum waves are said to have positive effects, at least according to those who hold that this theory is accurate (EMF).
Since ancient times, people have speculated that the warm glow of a salt lamp would have some beneficial health effects. However, this practice was not tried for the first time until the 14th century, when an old doctor named Kalid Azad conducted an experiment in which he placed a large lump of rock salt next to the beds of his patients.
He made the observation that these individuals appeared to sleep better and recover more quickly than is typical. Because of this discovery, he became even more interested in researching the impact that salt has on human health. Subsequently, he wrote several books about natural remedies that were based on the herbs and minerals that were found locally. One of these books included a chapter that discussed the beneficial effects that salt crystals could have.
As more time passed, many healers arrived at the same conclusion: if Himalayan Rock Salt was kept next to the bed, it helped treat sleeplessness as well as other health problems such as headaches, respiratory ailments, and arthritis; it also boosted mood and soothed one’s anxieties.
Even though there was no scientific proof to support these claims, many people started to believe that salt lamps had curative properties, which increased the lamps’ level of popularity.
This concept has been around for centuries, and even contemporary businesses use it as a marketing strategy to promote their wares. It is now impossible to determine the total number of ornaments that are sold annually; however, according to certain reports, the figure ranges anywhere from 200,000 to 2 million individual pieces.
Today, we have a great deal of knowledge regarding salt, including its chemical make-up (sodium chloride), its characteristics (it is hygroscopic), its applications (food preservation, de-icing, water softening, etc.), and much more. People who still believe that it can heal refer to ancient writings and the opinions of healers, and they pay no regard to the improvements that have been made in medicine and science. However, there is a subset of individuals who are adamant in their support of this technique and assert that salt lamps have been beneficial to them in some way.
