There are few things in life as soothing and relaxing as the warm glow of a campfire, and a Himalayan salt lamp offers a similar ambiance at home.

I’ve talked before about how I use them to help keep the air fresh and for their soothing red glow. Salt lamps have exploded in popularity over the last few years, along with some explosive claims about their benefits. In this article, I’ll break down the well-studied benefits, the anecdotal ones, and why everyone seems to love these lamps!

TIP: If you’re just looking for a high quality salt lamp for your home (and don’t care about the science), I have this one on my desk right now and love it.

What is a Himalayan Salt Lamp?

Salt lamps or HPS (Himalayan Pink Salt) lamps are large pieces of pure Himalayan Salt with a small bulb inside. They can be solid pieces of salt (like this one) or decorative baskets filled with large crystals of salt (like these). They offer a nice warm glow when lit and may be beneficial for indoor air quality.

Himalayan salt lamps are made from pure, food grade, Himalayan salt crystals. True Himalayan Salt comes from the western side of the Himalayan Mountains in the Punjab region of Pakistan. Once mined, this salt is hand carved into lamps or powdered to use as salt in recipes.

Why is Himalayan Salt Pink?

Regular table salt is primarily just sodium chloride. Himalayan salt is still about 98% sodium chloride, but also contains trace minerals like magnesium, potassium, and zinc. Trace minerals give salt lamps their hue, which can range from light pink to a dark orange/pink.

These beautiful lamps gained massive popularity recently and there are many benefits attributed to them.

But are these benefits actually backed by science?

Let’s find out…

How Does a Himalayan Salt Lamp Work?

Good question! We know the body needs salt for things like hydration, electrolyte balance, proper blood pressure regulation and for the nervous system. But all of these benefits come from consuming the salt internally (which I also do).

Most of us aren’t eating our salt lamps so the benefits come from another property of salt. Salt is naturally hygroscopic, which means it attracts water molecules to itself. The theory goes that salt lamps attract water molecules in the air.

Since water in the air can also hold allergens, pollutants and even bacteria, these substances get attracted to the lamp too. The heated salt lamp supposedly dries out the water vapor, leaving the particles attached to the salt. For this reason, many sources recommend wiping down the salt lamp with a cloth a few times a week to clean it.

Other sources claim that Himalayan salt lamp benefits are due to the creation of negative ions.

Do Salt Lamps Really Generate Negative Ions?

Many sources claim that salt lamps are natural negative ion generators, although there are some important points to understand:

What are negative ions?

At any given time, there are both positive and negative ions in the air. As a flashback to freshman science class:

An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge.

Positively charged ions are also known as cations, while negatively charged ions are anions. The positive or negative charge makes ions able to move and bond easily.

Negative Ions in Nature

Negative ions occur more often in nature and they are often created by things like lightening storms, sunlight, waterfalls, and ocean waves. Running water is considered nature’s greatest source of negative ions and may be one of the things that contributes to the refreshing scent of waterfalls and the beach. In fact, this is one of the reasons people often report feeling renewed or refreshed after a storm or after spending time at the beach.

WebMD explains some of the benefits of negative ions in the air:

Generally speaking, negative ions increase the flow of oxygen to the brain; resulting in higher alertness, decreased drowsiness, and more mental energy,” says Pierce J. Howard, PhD, author of The Owners Manual for the Brain: Everyday Applications from Mind Brain Research and director of research at the Center for Applied Cognitive Sciences in Charlotte, N.C.

“They also may protect against germs in the air, resulting in decreased irritation due to inhaling various particles that make you sneeze, cough, or have a throat irritation.”

And for a whopping one in three of us who are sensitive to their effects, negative ions can make us feel like we are walking on air. You are one of them if you feel instantly refreshed the moment you open a window and breathe in fresh, humid air.

Places like waterfalls and beaches where negative ions are naturally produced can have a negative ion concentration of up to 10,000 negative ions per cubic centimeter whereas busy cities can have negative ion levels as low as 100 ions per cubic centimeter.

But, Do Salt Lamps Generate Negative Ions?

Short answer: Yes. But not in large amounts.

Spending time in nature, especially around water, is definitely the best way to get exposure to negative ions, but salt lamps also generate small amounts, especially when used consistently over time.

Since positive ions are often created by electronic devices like computers, TVs, microwaves, and even vacuum cleaners, they can often exacerbate problems like allergies, stress and sleep trouble. Negative ions can neutralize positive ions (they bond together) and help cleanse the air. Additionally, salt lamps offer a soothing glow that many people find relaxing.

I don’t personally use salt lamps strictly as a negative ion generator, but keep them around the house, especially near electronics. If negative ions are the goal, using a negative ion generator would be a much more concentrated source.

Salt Lamps ARE Hygroscopic

As I said above, all salt, by its nature, is hygroscopic, meaning that it attracts water to its surface. In a Himalayan salt lamp, this water evaporates quickly due to the small amount of heat from the light source (this is also why salt lamps tend to sweat and appear wet in humid climates).

Small amounts of water vapor is present in the air and can carry things like mold, bacteria, and allergens. Salt lamps attract this water vapor and those items it carries to its surface and removes them from the air. When the water vapor evaporates, this MAY generate a small amount of negative ions.

The theory that salt lamps generate negative ions is not tested or well studied. That said, it is likely that due to the hygroscopic nature of salt, these lamps have a positive effect on air quality.

The Benefits of Himalayan Salt Lamps

Salt lamps may not be the negative ion generation panacea they are made out to be, but we have them in many rooms of our house for other reasons:

1. Great Night Light and Low-Light Lamp

Himalayan Salt Lamp Benefits for Clean Air and Reduced Allergies

Research has shown that different colors of light affect the body in different ways. My own doctor recommends avoiding blue light after sunset because it can interfere with circadian rhythm and disrupt sleep hormones.

Unfortunately, many modern light sources like cell phones, tablets, computers, and TVs emit a lot of blue light and many of us spend a good majority of time staring at these screens, especially in the evening.

Salt lamps, on the other hand, offer a warm orange glow, similar to the orange hues found in a campfire or by candlelight. For this reason, they are a great light source for the evening and can even be used as a night light without negatively affecting sleep.

I often wear orange sunglasses at night if I’ll be on the computer or watching a movie to avoid blue light, and we use mostly salt lamps and other low and orange lights after dark for mood lighting.

2. May Improve Air Quality

As mentioned, salt lamps are not a spectacular source of negative ions. However, due to their hygroscopic properties, they may improve the air in other ways. Besides offering a soothing glow, they can attract pollutants in the air and even help neutralize the effects of electronics.

3. Light and Color Therapy Benefits

These soothing lamps may also help boost mood and energy levels, especially for those with Seasonal Affective Disorder (SAD). The soft orange hues are one of the soothing colors often used to calm mood and increase focus. The small amounts of negative ions may also be helpful in boosting mood as well. But, if you’re looking for the benefits of the negative ions, spend some time outside instead!

4. Soothing for Allergies

My brother-in-law has struggled with asthma and allergies for much of his life and he found relief after using a Himalayan salt inhaler. Others notice a difference from having salt lamps in their homes or offices. I haven’t found any studies that have looked into why, but the anecdotal evidence is strong from allergy sufferers.

How To Choose a High Quality Salt Lamp

It is possible to buy machines that create negative ions, but I’ve found that spending time outdoors and having salt lamps around the home indoors are less expensive alternatives that offer other benefits as well.

We have salt lamps in most rooms in our home and enjoy them in winter months when it isn’t possible to have the windows open or to spend as much time outside. We now have a solid salt lamp and a basket lamp in several rooms of our home and I love them for their ambient glow and orange color.

Salt lamps cost less than many other types of lamps, and a high quality one can last for decades.

If you are interested in adding a salt lamp to your home, choose ones with these features for best quality:

  1. Orange Color– Darker colored lamps are typically considered higher quality. Lamps should specify that they are 100% Himalayan salt, as cheap imitations may use lower quality salt.
  2. Size– The bigger the salt lamp, the bigger the affect. Smaller lamps weight 5-6 lbs while larger ones can weigh up to 50 lbs. Smaller lamps are typically much less expensive, so we keep 1 or 2 in smaller rooms and 2 or 3 in larger rooms of our home.
  3. Rough Surface– The surface area of a salt lamp determines its hygroscopic potential. Rougher lamps have a higher surface area than smooth and polished lamps and are more effective at improving air quality. In my opinion, they also look better and are a great decoration for most rooms.
  4. Bulb– The hygroscopic benefits are due to the salt and heat together so it is important to use a heat-producing bulb. LED bulbs don’t accomplish this. I use these inexpensive bulbs.

These are a few of the Himalayan Salt Lamps I’ve tried that meet these criteria:

Himalayan Salt Lamp Benefits: Bottom Line

Salt lamps aren’t a panacea and they don’t take the place of a quality air filter. They don’t create large amounts of negative ions like you’ll find in nature, especially around water. If negative ions are the goal, taking a hike or a swim in nature is a much more efficient way to get them.

Himalayan salt lamps are a beautiful light source that may offer the benefits of color therapy, by cleaning the air hygroscopically and in alleviating allergies. They are an inexpensive no-blue light source to use after dark and as a sleep-friendly night light for kids.

At the end of the day, they aren’t going to fix any health problems on their own or drastically improve indoor air quality. They are, however,  a beautiful and eco-friendly light source that produces a healthy spectrum of light. If you are choosing lamps for your home, they are a great option to consider.

    All the lamps you link to have dimmer switches but I’ve read about how dimmer switches create a lot of dirty electricity. Are there any brands you recommend that have simple on/off buttons?

    I have heard of the benefits of salt lamps for quite awhile and have ordered one to try. I am wondering if I should also use an air purifier in the same room. Thank you.

    As a new salt lamp user, never dealt with any before. My lamps came with a dimmer switch, my question is, to what light setting is recommended for the maximum benefit of these lamps to be used as a health product vs decor product?

  4. Beth Avatar

    Any ideas on where to find a replacement cord / lightbulb assembly for a salt lamp that DOES NOT have a DIMMER SWITCH, since dimmer switches give off unwanted EMF radiation? I’m trying to find one with a simple ON/OFF switch without success.

    Do you use light bulb bulbs for salt lamps or is there a special bulb to use? I have four and the bulbs burned out on all and my son tossed them so I’m not sure which to buy. Thanks for any info!

    It’s worth reiterating that salt lamps produce little to no negative ions. This has been explored by Prof. Jack Beauchanp, Dr. Nathan Dalleska, and host of Yourube channel “Veritasium”, Derek Muller. Here is the episode where they bust the myth about Himalayan salt lamps producing any detectable negative ions: https://youtu.be/ZQ–scjcAZ4

    In addition to disproving claims that these lamps produce any measurable amount of negative ions, they also tested ion generators. They found that these electronic products are able to produce ions, yet this also has an unfortunate side effect: producing toxic ozone!

    Best to avoid these products all together and simply go outside, hike to a waterfall, go to the beach, or just go outside after it rains.

    I take Balanced Electrolytes, and use Potassium as the Key element to How much I take per day as we all need 4700MG per day, electrolytes are Minerals, Next I sleep Grounded this provide Electrons, Electrons are what we get when Negative Ions what are Uptake is by the body, as Negative Ion have free electrons to donate, so they are a electron donor. So far there are 2 Raw Materials that we need for cellular ATP energy and Cell replication, when we make New cells we must Look at PH = Voltage, as raising your PH increases your cellular Negative Voltage, this is Healthy, and needed for Healthy cell replication Minus – 50mv Negative are needed to make new healthy cells. Lower PH reduces negative voltage and can even cause a voltage polarity shift to positive voltage is when all Major illness happens including cancers. 1. electrolytes minerals, 2. Electrons through Grounding and/or a Negative Ion generator (one that produces NO Ozone as ozone is bad) When you uptake electrons in to the body at the cellular level this also Oxygenates the red Blood cells at the same time, Electrons repel each other like reverse polarity Magnets this is why Red blood cells dont Clot since they repel electrons act like a blood thinner as well as a circulation Booster, this tells me that heart attacks and strokes could be eliminated If we increase our electron Uptake to Maximum level (you Cant have to many electrons) at least sleeping grounded, add a Negative Ion Generator for when you Not on a grounding mat. Electrons Boost Cell Oxygen transport, by increase red blood cell Oxygen transport you in essence alkalizing your body at the cellular level, remember PH level = voltage, ATP voltage. I have a PH Level chart that shows PH level as a Voltage within the Cell. this has everything to do with Cellular energy and cell replication Health. Low or Positive Voltage mean Unhealthy, sick, disease, Cancer. I cannot upload the PH level = Voltage chart. Healing the Body Electrically using the items so the Body can make the Raw Materials it needs to Raise the Negative Cellular Voltage, which means raising your cellular PH, as I mentioned above
