“A Himalayan salt lamp is a lamp made from a large piece of Himalayan salt, sourced from the Himalayan mountains. A hole is drilled into a salt chunk so that a lamp or tealight can be placed inside. These atmospheric lights are available in various shapes and sizes. The reason I have four Himalayan salt lamps in my house is mainly for the cosy natural atmosphere they create. However, the lamps are also said to have a ‘purifying’ effect. I’ve researched exactly how this works. Are you joining me?”

Ionization
An ionizer is a device that ionizes molecules. Ionization is the process in which an atom or molecule loses or gains an electron from its uncharged state. Ionizers produce a stream of charged particles (ion flow) in the air that cause dust particles in the environment to settle. In theory, this has a beneficial effect on air quality and may therefore affect health issues related to air quality, particularly asthma (De Meer, Duijm & Hall, 2010). Himalayan salt lamps are said to produce and subsequently release negatively charged ions into the air by heating the salt (through the lamp or candle). Research has shown that the amount of these ions is so low that it cannot be considered to have a similar positive effect (Ferreira, 2016).

Humidity
The air in your home contains moisture, known as humidity. Salt attracts water, so the salt lamp in your home draws in some of the humidity. Bacteria, allergens, and moulds present in the air are also drawn and attracted to the salt lamp, thereby “purifying” the air in your home. Salt doesn’t attract moisture, but the salt lamp consists of a molecular compound of NaCl (Sodium Chloride). The moisture in the air that comes into direct contact with it undergoes a chemical reaction. The H2O in the air that comes into contact with the salt lamp/NaCl undergoes a reaction. So, this would mean that only the moisture and bacteria floating around the salt lamp are attracted to it and purify that particular area of air.

So, if you want to completely “purify” the air in your home, you would need to stack quite a few salt lamps both horizontally and vertically so that the moisture in contact with the lamp can be attracted.

Just kidding! But if you do want to effectively purify the air in your home, you might consider investing in an air-purifying fan from Dyson, for example. Nonetheless, salt lamps remain very atmospheric, and that’s why I have them in my home. If you’re interested in getting a salt lamp yourself, I’ve listed some places below where you can buy them. However, it’s more fun to go to a store and choose one that you really like. Salt stones come in various types and sizes, and they are also reasonably affordable. The most popular variants are the tea light holders and the lamps.

Tip for the Rotterdam resident (or if you’re in Rotterdam): Pay a visit to Mystiek in Rotterdam at Schiedamse Vest 79 (Witte de Withkwartier). It’s a delightful store where you can find everything related to spirituality and health.
