Lamps from pieces of salt are quite popular among fans of a healthy lifestyle, and marketers attach interest in them, promising invaluable health benefits. We decided to check if they really have almost magical properties.
Description of salt (or, as they are also called, salt) lamps in online stores health goods and Houses, souvenir products And on Portals About a healthy lifestyle, it says that they Clean air from bacteria, contribute to the treatment of organs Breath, in the solution skin And allergic problems, facilitate headache for migraine, help prevent asthma, diabetes, A cold and other diseases, strengthen immunity, neutralize the harmful radiation From computers.
Salt lamps are ceiling from large pieces of salt, often pink Himalayan (we are already They wrote The fact that its benefits when eating are somewhat exaggerated), inside which a light bulb is inserted. These lamps are supposedly ionize The air, attracting water particles, which then evaporate in the form of a salt solution due to heating. Hence all their alleged miraculous properties. It is worth noting that the study that we brought above was conducted in Pakistan, namely in this country produced Most of the Himalayan salt. Other studies that would confirm these conclusions could not be found.
Air ionization really has a certain positive effect on health. So, for example, during research was Determinedthat negative ions can help with seasonal depression. However, in the course meta -analysis The previously conducted studies are the consistent effect of ionization on the mood or a sense of well -being was not confirmed. It is worth noting that the studies used industrial, very powerful air ionizers, which is unlikely to compete with which one single salt lamp.
The assumption that such lamps can help people with lung diseases are based in practice halotherapy (treatment with saline inhalations). However, scientists have not yet been able to come to an unambiguous conclusion about its effectiveness, the American ASTMA and Allergy Fund does not recommend Use this method. Also for researchers failed discover any statistically significant influence ionized air on respiratory functions compared to ordinary air. Powerful ionization can really Clean air from allergens, such as dust and dust mites, but it can also lead to education In the air of ozone, which is harmful to people with asthma and respiratory diseases.
Ionization supposedly helps to deal with harmful radiation from computers and household appliances. We are already Disassembled The myth that cacti supposedly protect from such radiation, and wrote that they should not be so afraid of him so much. This Confirm and WHO experts.
There are some data that negative ions reduce the risk of cardiovascular diseases, but they are based on experiment, during which rats consumed negative ions in a very high concentration. Here, as in the case of research on the influence of ions on the mood, it is necessary to take into account the scale: the rats are much fewer people, and the number of negative ions that they received was significantly higher than what one lamp can theoretically produce.
However, do the same negative ions produce salt lamps at all? We were not able to find authoritative scientific research that would confirm the effectiveness of salt lamps. The American popularizer of science Derek Müller decided not to delve into scientific works, but check Everything is in practice. He bought a salt lamp and came with it to scientists of the California Technological Institute. In the laboratory, they turned on the lamp and, using modern equipment, tried to fix the number of negative ions produced by it. To their surprise, the level of ions was not just low, it was not at all! That is, the lamp had absolutely no ionizing effect.
Kalteha scientists explained this by the fact that salt does not suit the crystalline lattice for such purposes: it is necessary for too much energy to release the negative ions of chlorine, much more than one can produce a single bulb. Therefore, the ionization of air is useful for health or not - salt lamps will not help with this.
Maybe the content of a huge amount of useful substances in salt, which Declated Manufacturers and sellers can have some beneficial effect on our health? However, there are questions here. Firstly, not all of them are so useful (for example, radioactive polonium and a poisonous arsenic can hardly help a person very much), secondly, they are kept in salt in small doses, and thirdly, it is not clear how they can enter the human body.
Thus, we were not able to find authoritative scientific research that would confirm the healing properties of salt lamps. In addition, many authoritative medical Portals And Clinics Also investigated the question of the benefits of salt lamps, and all of them came to conclusionthat, in addition to decorative functions and soft muffled light, which can have a calming effect, such lamps do not help our health. Our colleagues-factchera from Snopes We also studied this issue, and, like us, came to the conclusion that the benefits of salt lamps are very doubtful. Separate experiments indicate that these lamps do not produce any negative ions that supposedly should have a positive effect (although it is so useful about whether ionization is really useful, scientists have not yet come to a consensus).
