Advocates say the lamps work in two ways:
Pull in particles. These lamps supposedly attract allergens, toxins, and pollutants to their surface.
Possibly release negative ions. Some people believe negative ions in the air have health benefits.
Ions are molecules that have undergone a change in charge. Negative ions have gained an electron. Positive ions have lost one.
Ions are all around us. Some come from particles from outer space that make their way to Earth. Others form closer to home, from radiation, sunlight, lightning, or the collision of water droplets in a waterfall.
Some people say they feel more refreshed and clear-headed after a storm, a feeling they believe is due to the amount of negative ions in the air. Commercial ionizers and purification systems also produce negatively charged ions to create cleaner and more comfortable indoor spaces.
Himalayan salt lamps supposedly produce negatively charged ions while water molecules from the air attract to -- and then evaporate from -- the warmth of its surface. Those who believe in the health benefits of these lamps give negative ions much of the credit.
Although a few studies show some benefits from negative ions, the evidence that salt lamps improve health is lacking.
Mood and sleep. Some people believe that positive ions in the air increase anxiety, crankiness, and other unpleasant feelings. They say that negative ones ease stress, anxiety, and depression, and improve overall well-being.
Studies with mice and rats suggest that high amounts of negative air ions alter levels of serotonin, a chemical that contributes to feelings of well-being.
In some human studies, negative ions at high concentrations did lessen depression slightly, but they didn't have much of an effect on anxiety levels or sleep.
A very small study shows that people did better on thinking skills tests when they were in a room where the paint on the walls had a high concentration of total air ions (both positive and negative ions). But the paint had no effect on their general well-being.
Asthma and allergies. The notion that negative ions may improve breathing has led to a few studies on the topic. In most of them, negative ions didn't ease breathing or asthma symptoms. They also didn't lower inhaler use in children and adults with chronic asthma.
Cleaning the air. Negative ions do have some ability to clean harmful particles from the air. When ions build up on bacteria or pollen, they neutralize the pollutants. Studies suggest that negative and positive ions may kill germs, though exactly how isn't clear, and some experts say the germ-killing may be due to other reasons. In any case, there's no evidence salt lamps have this effect.
Salt lamps are often claimed to improve the air quality of your home.
More specifically, they are advertised as being beneficial for people with allergies, asthma, or diseases that affect respiratory function, such as cystic fibrosis.
However, there is currently no evidence that using a Himalayan salt lamp can remove potential pathogens and improve the air quality of your home.
The claim that they are good for people with respiratory conditions may be partly based on the ancient practice of halotherapy.
In this therapy, people with chronic respiratory conditions are said to benefit from spending time in salt caves due to the presence of salt in the air.
Though some studies have found that this practice may be beneficial for certain respiratory conditions, more high-quality studies are still needed.
Furthermore, tests on air ionizers, which emit high levels of negative ions, haven't yet been shown to benefit people with asthma or improve respiratory function .
Another frequently made claim is that Himalayan salt lamps can boost your mood.
Some animal studies have shown that exposure to high levels of negative ions in the air may improve levels of serotonin, a chemical involved in mood regulation.
Yet, older human studies investigating claims regarding the psychological effects of air ionization found no consistent effects on mood or feelings of well-being .
However, researchers did find that people with depressive symptoms who were exposed to very high levels of negative ions reported improvements in their mood.
Nevertheless, the link they found wasn't dose-related, meaning that people's mood improvements couldn't be explained by the dose they received. Thus, researchers questioned whether the link was causal .
Additionally, it's very unlikely that salt lamps could expose you to the high number of negative ions used in these studies.
Studies have not yet examined the effects of Himalayan salt lamps on sleep.
However, a 2013 review of the effects of air ionization on relaxation and sleep didn't find any evidence of a beneficial effect.
Thus, even if salt lamps do affect the air environment, it's not clear if this would have an effect on sleep patterns.
It's possible that using the dim light from a Himalayan salt lamp may help promote sleepiness toward the end of the day if you use it to replace bright electric lights.
This is because bright light before bed can delay production of the sleep hormone melatonin.
However, this isn't specific to salt lamps, and the theory hasn't been tested.
Unfortunately, this magic lamp won't grant you better health and wellness. This is true whether you spring for an authentic version or settle for a fake one.
"There"s not a lot of evidence to support the idea that Himalayan salt lamps provide some – if any – of the supposed health benefits," says Dr. Vyas.
One study did suggest that negative ions might decrease depression in some people. However, these lamps don't produce enough negative ions to make a difference.
Negative ions, in large enough quantities, have also been shown to kill dust mites in the air. But again, these lamps do not produce enough to have any real benefit. There is also no evidence to support the idea that the lamps can absorb toxins from the air around you.
Other people argue that the warm, glowing light provides a relaxing and calming atmosphere, which in turn promotes tranquility and improves mental health. However, this theory is purely anecdotal.
If you're serious about trying to improve the air quality in your home, you can try an air purification machine, which have been shown to remove particles from indoor spaces, like allergens, smoke and mold.
So while these lamps continue to grow in popularity for their artful and soothing vibe, it's best to take all of the claimed health benefits with, well, a grain of salt.
Still, if you like the lamp's pinkish hue, there's no need to get rid of it. Just be sure to practice good fire safety and keep the lamp in an area where it can't be knocked over and out of reach of children and pets.
You don't know what you're missing if you've never owned a Himalayan salt lamp. It's like having an open window – a softly glowing natural source of fresh, clean air – on your desk, in your living room, next to the bed, or anywhere you choose to put it.
Before we dive into the health benefits of using Himalayan salt lamps in your home, it may be helpful to first have a brief chemistry lesson:
All matter (the human body, air, water, etc) is made up of molecules which are made up of atoms which are made up of three types of particles: protons (positive charge), electrons (negative charge), and neutrons (no charge). Electrons orbit their molecules like planets revolve around a star. Occasionally an electron flies off and when it does, it leaves behind a positively-charged ion whose sole purpose in life becomes to fill the void left by its little lost electron. In other words: it wants to steal a replacement electron from another molecule. Due to differences in molecular structure (number of electrons in the outermost orbit, strength and structure of electron bonds, etc) some materials lose electrons much more easily than others.
With this basic understanding of the behaviors of positive and negative ions fresh in your mind, let's take a look at the top 10 benefits of the Himalayan Salt Lamp.
Salt Lamps Cleanse & Deodorize the Air
Probably the most well-known benefit – and why the majority of people use them – is due to their incredible power to remove dust, pollen, cigarette smoke, and other contaminants from the air. "But how do they do this," you ask? "It's just a big chunk of salt with a light bulb inside, right?"
Well yes, but no. There's much more to it than that.
Himalayan salt lamps purify air through the power of hygroscopy, meaning that they attract water molecules from the surrounding environment then absorb those molecules – as well as any foreign particles they may be carrying – into the salt crystal. As the HPS lamp warms up from the heat produced by the light bulb inside, that same water then evaporates back into the air and the trapped particles of dust, pollen, smoke, etc remain locked in the salt.
Reduce Allergy & Asthma Symptoms
Because Himalayan salt lamps remove microscopic particles of dust, pet dander, mold, mildew and the like from the surrounding air, placing a lamp or two in the rooms where you spend the most time can seriously cut back on allergy symptoms. Even people who suffer from asthma should notice a big difference after a week or two. (In fact, Himalayan pink salt is so good for your airways, there are even HPS Inhalers!)
Eases Coughing
When the Himalayan salt lamp heats up and begins its hygroscopic cycling of airborne particles, it also changes the charge of the molecules which are released. (Remember our chemistry lesson?) The majority of homes are filled with positively charged ions which aren't particularly good for a person's health. The positive ions are created by a number of things, but the primary source for most of us is from our electronics.
One of the health detriments of breathing lots of positive ions in the air is that the cilia (microscopic hairs) which line the trachea (aka: windpipe) become sluggish and don't work as well to keep contaminants out of our lungs. As a Himalayan pink salt lamp absorbs water and particles from the air, it also takes positive ions with them. Then, when the heated salt releases cleansed water vapor back into the air, it also expels negative ions which have the opposite effect on our airways – increasing cilial activity to keep your lungs clear.
What all this means in a nut shell: Besides removing contaminants from the air, Himalayan pink salt lamps also help your body to filter air more efficiently so any foreign particles you do happen to breathe won't make it into your lungs.
Increase Energy Levels
Taking a drive through the countryside with the windows down, spending time at the beach or camping in the mountains, or simply taking a shower first thing in the morning are all things that many people find invigorating. It's not a coincidence that these are all activities which expose us to increased concentrations of negative ions such as those generated by Himalayan salt lamps. The fact is, positive ions sap our bodies of energy. Unfortunately, it's all too common for us to try to diagnose the problem as something else entirely.
If you constantly feel tired and don't know why, try keeping a Himalayan salt lamp in the room or rooms where you spend the most time. After about a week, you should notice a difference.
Neutralize Electromagnetic Radiation
Nowadays, most of us are living in a metaphorical ocean of electromagnetic (EM) radiation which flows from our electronics (ie: television, computer, cell phone, tablet, appliances, sterio, etc). While they may be invisible, the long-term effects of EM exposure can be quite serious. Constant exposure to EM radiation is known to increase stress levels, cause chronic fatigue, and decrease the body's immune response, among other things.
As they emit negative ions into the air, Himalayan salt lamps work to neutralize electromagnetic radiation. Keep one next to the computer, television, and any other electrical devices which you use frequently to reduce the potential danger to you and your family.
Better Sleep
Another side effect which results from over-exposure to positive ions in the air is that it robs you of quality sleep. This happens because those positively-charged particles can actually reduce blood and oxygen supply to the brain resulting in irregular sleep patterns. Himalayan pink salt lamps are natural negative ion generators, thus they can help to reverse this problem. Keep one or two around your bedroom to improve the air quality so you can get a better night's sleep.
Remember, even if you're like me and you can't sleep unless the room is totally dark, you can always turn the lamp off at bedtime. Just leave it on for the rest of the day so it can do its work while you're awake. People in humid climates should be aware that HPS lamps tend to weep when the salt becomes cool. You'll definitely want to protect surfaces by placing a saucer underneath and be sure to follow the instructions for use and care which should be included with your lamp!
Improve Mood & Concentration
Himalayan pink salt lamps are a great way to naturally enhance your mood or to help you relax and unwind at the end of the day. At the same time and on the opposite side of the coin, HPS lamps are great for improving concentration. Again, this is due to the effect of the negative ions on your body, improving blood and oxygen supply to the brain and other organs, as well as providing a boost of serotonin – the neurotransmitter which makes us (literally) feel happy.
Treat Seasonal Affective Disorder
In addition to generating negative ions which improve mood and energy levels, the soft, natural light given off by a Himalayan pink salt lamp is close enough to the warm glow of sunshine that they can even be used to relieve the symptoms of Seasonal Affective Disorder. This year when the days get shorter, fight back the lethargy by surrounding yourself with a few HPS lamps set on timers.
Reduce Static Electricity in the Air
While not a "health benefit" at first glance, static is pesky stuff. It causes stress, embarrassment, and frustration. Static zaps you when you least expect it, as you're reaching for a door handle, kissing your husband or wife before bed, or trying to pet your dog or cat. Static can give you a bad hair day, make it impossible to clean crumbs or coffee grounds off of the kitchen counter, and even cause you to accidentally go to work with a sock stuck to the back of your shirt…
(Okay, so that last one may have been a little over-the-top.) The point is, static electricity can be a huge pain and Himalayan pink salt lamps are a natural way to neutralize the airborne ionized particles which cause it.
Environmentally-Friendly Light Source
Last, but not least: Himalayan pink salt lamps are environmentally friendly. While only an estimate, the reserves from which HPS is mined measure somewhere between 80 and 600 million tons and is projected to last for at least another 350 years at the current extraction rate. The base of an HPS lamp is generally carved from a sustainable wood such as neem. Some lamps use a low-wattage bulb which consumes very little energy while others are powered by a lit candle.
Do you have a salt lamp in your home? If not, you may want to consider purchasing one after reading post. Himalayan salt is known for its many health benefits, and today we are going to discuss a few of them.
Air quality. One of the most surprising health benefits of Himalayan salt is that it can help to improve your respiratory system. If you suffer from allergies or asthma, Himalayan salt can help to relieve some of your symptoms. The salt helps to filter the air and remove toxins, making it easier for you to breathe.
Deeper, more restful sleep. Another surprising benefit of Himalayan salt is that it can help to improve your sleep. If you suffer from insomnia or other sleep disorders, the salt can help to promote deeper and more restful sleep. The salt helps to balance your body's natural rhythms, making it easier for you to fall asleep and stay asleep.
Skin health. Himalayan salt can also help to improve your skin health. The salt helps to balance your skin's natural oils, which can help to reduce acne and other skin conditions. The salt can also help to exfoliate your skin, removing dead skin cells and revealing healthy, new skin.
Energy. Finally, Himalayan salt can also help to boost your energy levels. If you are feeling tired or sluggish, the salt can help to give you a much-needed energy boost. The salt helps to improve circulation and increase oxygen levels in the blood, giving you more energy and vitality.
Himalayan salt is an incredible natural resource that has many benefits for your health. If you are looking for a way to improve your overall health, consider adding Himalayan salt to your diet or using a Himalayan salt lamp in your home. You may be surprised at how much this simple change can help you to feel better and live a healthier life.
