This is what just one Himalayan salt lamp company touts: Emits negative ions that fight against electromagnetic radiation and fights fatigue and sluggishness; It also increases the flow of oxygen to the brain, protects against airborne germs, increases work productivity and creativity, improves bone strength, soothes allergies; Sleep better & wake refreshed.
First, Electromagnetic Radiation is emitted from your TV, computer, cell phones and all electronics that seem to be attached to our hips and in some cases used in our daily lives more than 10 hours out of our day. These daily emission of electromagnetic radiation contributes to lowering the melatonin levels within our bodies. Lets look at why melatonin is so important to us. Melatonin plays an important role in the sleep cycle, sometimes called “The Dracula” of hormones as it only comes out at night. Lower levels of melatonin affect your immune system, your mental health, and is the regulator of sex hormone production. This is huge. Melatonin deficiencies have shown in patients with cancer, heart disease, ulcers, and even Alzheimer's. I personally had a low level of Melatonin when I lost my thyroid and my sleep was disrupted regularly. Aside from the issues of not having a thyroid, not being in the right mind as well due to lack of sleep and proper necessary hormone levels throughout the body was truly awful.
When the heat from the salt lamp warms the crystal, a negative electrical charge is emitted, ionizing our atmosphere, which in fact helps to neutralized harmful EMF radiation. Just imagine though, this small Himalayan Salt Lamp and the huge amounts of electronics that we surround ourselves with daily. Negative Ionization is truly a benefit here, but, unless you are a person who is off the grid, so to speak, the electromagnetic radiation of all of these electronics, far outweigh any negative ions the salt lamp can produce. You can certainly do better for yourself here and put a salt lamp in every room you spend a considerable amount of time in, including your office, which might be significantly favorable in the hormone department of your body.
Secondly, negative ions are proven to increase the oxygen in our brain and other organs, as well as boosting the serotonin levels which results in higher mental energy and alertness, and makes us feel happy. It's for this reason that most people feel more refreshed and happy while at the beach....Running water is considered the world's greatest source of negative ions. While with this lamp, we're talking about just a small amount of negative ions in your home or work space. But doesn't that account for something? In my world and belief system, every little bit of good you do for yourself is growth to all of you; physically, mentally, and spiritually. And every little bit of kindness you give to yourself, is negating (even if just a minute amount), the toxicity that surrounds us on a daily basis.
Thirdly, the salt lamps are also said to be Hydroscopic which means it attracts water vapor from the air to it. In attracting the water vapor, along with that vapor, it's also attracting things trapped inside the water molecules like mold, bacteria, allergens, and other contaminants improving our air quality by trapping it to them into the salt crystal. Talk to the person who has severe allergies, or severe asthma and see how they feel about improved air quality. To them, even the tiniest amount of improvement can be expressed as monumental in their ability to breath and feel well because they are getting more oxygen to their brain than usual during allergy season. Personally speaking on allergies and someone who is allergic to dust; I work in an office building that is not always properly cleaned or air purified as maybe I would do to my own home, and this is life altering daily, not just allergy season.
Salt lamps may even help with SAD – seasonal affective disorder. Due to the soft orange hues and soothing colors reminiscent of a sunshine effect, they tend to be calming and increase can even increase clarity and focus of daily chores or work that sometimes gets to be overwhelming during this time. Some people suffering from SAD have been starting to put these lights on timers to relax the mind during a time of less sunlight. Again, it may not be a cure all but any bit of relief is better than no relief, and this is all natural.
So this is my own personal hypothesis. Just as being on a beach with the salt air, helps many people feel and breath better, so too, does the salt lamp. While they may not may an enormous difference in negative ions, a benefit is a benefit and better than none at all. Salt lamps definitely don't hold a candle to an air purification system, but much like the relief attained by breathing in the salt air at the seashore, it can be an additional healing asset in your life. Truly, the way I see it is, you absolutely could be a “glass half empty” kind of person, and don't want to hear about any of these so-called “tiny” perks because you consider them to be too insignificant to care about. That is definitely your right, but in my opinion, any slight improvement to your health, mind, & body, is worth it, because YOU are worth it!! Lastly, with the aesthetics alone, you have can add a salt lamp to any room to serve merely as a beautiful accent piece.
I'd love to hear what experience you may have with a salt lamp. Immediately, when I got mine, I noticed a difference in my breathing as well as my energy level, which I'll be honest, truly did surprise me. I just love mine!!
