Himalayan Sea Salt: Misunderstandings, Health Risks, Dangers?

15 SECOND SUMMARY: Himalayan sea salt is a coarse pink salt that is believed to afford a wide range of health benefits.

There is no science at all behind these claims. Himalayan sea salt is a great example of why bloggers need to be careful when posting information relating to health in order to make sure that they follow the Hippocratic Oath of ‘Doing No Harm’.

The Patient Who Mistook Himalayan Sea Salt For BP Lowering Medication

I keep a beautiful pink Himalayan sea salt lamp on my desk at work. I love the way the light diffuses through the salt spreading a nice orange-pink glow. It also vaguely reminds me of vacation time by the sea.

Last week I found myself in an awkward situation because of the lamp. A patient noticed the lamp and misinterpreted the fact that I had a lamp on my desk as evidence that I was a raving fan of Himalayan sea salt. She then began to wax lyrical about Himalayan sea salt.

This lady uses pink Himalayan sea salt on a daily basis for a long list of cures. She cooks with it and says that the meat is very tender and tasty. She drops Himalayan sea salt crystals into her bath for detoxification. She also takes Himalayan sea salt on a daily basis to boost her metabolism and strengthen her bones.

Worryingly since she discovered Himalayan sea salt she had stopped her blood pressure tablets because she had read that Himalayan sea salt is very effective at lowering blood pressure. I was not aware of any research but my first impression was that it seemed counterintuitive to me that a salt based compound would lower blood pressure.

I found myself feeling very uncomfortable. Yes I have a cute Himalayan sea salt lamp but that does not mean anything more than that. As Freud said ‘sometimes a cigar is just a cigar’ and I would say that ‘sometimes a Himalayan sea salt lamp is just a sea salt lamp’.

Having said that, I have to admit that I am careful not to have other things in the clinic room that might be misinterpreted by a patient. As an example I don’t write with branded freebie pens from drug companies. Equally I don’t keep any unhealthy food but to be honest I don’t eat or drink unhealthy things so this is not a big deal. Maybe I need to retire the lamp now to a less public place!

The lady had interpreted an online blog as saying that taking Himalayan sea salt would lower her blood pressure. She had stopped her BP tablets and was adding extra Himalayan sea salt to her diet. Prior to finding the blog on sea salt she had been taking her medications and her BP was controlled. Not surprisingly her BP was not controlled on this visit.

I told her that I had no idea about the science behind Himalayan sea salt and that she needed to restart her regular BP medications and stop taking sea salt. I promised to remain open-minded and do a little research into Himalayan sea salt and let her know what I found out.

What’s Actually IN Himalayan Salt?

Some blogs have referred to spectral analysis of Himalayan salt and the famous claim about it containing 84 trace minerals and elements. The problem is that the spectral analysis was done in-house by a distributor of the salt and as such is not a reliable source of information for us.

Claims about the health benefits (or the toxicity) of HSS components must be tempered unless someone comes up with a credible spectral analysis of it.

Does Himalayan sea salt reduce BP?

I looked in every academic resource I could think of and found no reports of Himalayan sea salt lowering blood pressure. I could not even find a single case report of an anti-hypertensive effect of Himalayan sea salt. I contacted nutrition mastermind groups that I am part of but came up with nothing. Experts that I spoke to said ‘It is not even biologically plausible that Himalayan sea salt would lower blood pressure. Salt raises BP’

Bottom Line: There is no evidence that Himalayan sea salt lowers blood pressure and it is biologically implausible that it would have an anti-hypertensive effect.

Does Himalayan sea salt strengthen bones?

There is nothing to be found in the scientific literature to support the use of Himalayan sea salt for strengthening bones. I cast a wide net and looked for individual reports of people who found it helpful.

All I found were random blogs which listed bone support as one of the many benefits of Himalayan sea salt but the claims were not referenced.

Bottom Line: The role of Himalayan sea salt in bone density seems to be an urban (or bloggers) myth!.

Does Himalayan sea salt improve circulation?

Again I couldn’t find anything credible on Himalayan sea salt as a way to boost circulation. Many people with circulation issues have high BP too so we need to be super careful about making unfounded claims regarding this condition.

Bottom Line: The role of Himalayan sea salt in improving circulation seems to be another urban (or bloggers) myth!

Does Himalayan sea salt reduce acid reflux?

There are 20,000 online posts for studies relating to the treatment of acid reflux. Guess how many mention Himalayan sea salt? None!

Bottom Line: Not one of the 20,000 studies on treating acid reflux mention Himalayan sea salt!

Is Himalayan sea salt healthier than table salt?

There are two interesting posts online by practising MDs who have felt the need to write about the risks of Himalayan sea salt. The two posts are almost identical in content. They say that Himalayan sea salt is believed to be healthier than commercial sea salt.[1-2]

However on closer analysis we can see that the key issue in terms of salt health is the sodium content. The sodium content is identical between Himalayan sea salt and commercial salt. This is exactly where my patient ran into trouble.

Assuming that ‘natural’ is healthier does not always work out. What matters is the amount of salt. Sure go for Himalayan sea salt if you like the color or coarse texture but you still need to take it in moderation.

Bottom Line: Himalayan sea salt has the same sodium content as commercial sea salt and needs to be taken in moderation if at all.

What About Himalayan Salt Lamps?

The lamps consist of a large hollowed out piece of Himalayan sea salt with a light bulb inside.

Having a pink Himalayan sea salt lamp is almost a status symbol which says ‘the owner of this lamp is eco friendly and green’. But do they do anything else?

Himalayan sea salt lamps are promoted for their health effects. The promotional blurb that goes with the lamp goes as follows:

The salt in the lamp attracts water and dust from the air. The heat from the lamp then warms up the salt which allows evaporation of the water but keeps the dust and other micro-particles attached to the salt. The lamp is believed to attract cations from the air and release anions.

It is really hard to believe that there is any biological plausibility behind any of this. At best, it sounds like new age mumbo-jumbo to me where you take anything negative and transmute it “back into the light”. At worst, it sounds like a huge one-way dust magnet sitting in your roorm

In any case, all of this is supposed to be good for our health and especially for asthmatics.

But is there any proof?

Are They Good For Asthma?

Put simply: There is not a shred of evidence that Himalayan salt lamps can help people with asthma. Nothing, nada.

I did come across something that sounded a little similar in the medical literature and so checked that out in order to be really open-minded.

Speleotherapy is a treatment for asthma which is used mostly in Eastern Europe. Speleotherapy involves spending time in a subterranean environment. This can either be for a short visit or for a longer stay as there are even wards in some of the speleotherapy caves in Europe. It is believed that the mixture of the salt, radiation, humidity, air pressure or the underground environment somehow helps asthma.

A group of UK based researchers did a really extensive review on speleotherapy (Beamion).They even contacted speleotherapy centers to try to get a comprehensive understanding of this treatment. They published their findings as part of a Cochrane review and concluded that there was no scientific basis for speleotherapy either.

A small pilot study which is about to be published does show some benefit for salt chamber or halotherapy for children with mild asthma (Bar-Yoseph). Just to be clear, this study used haloegenerators to emulate the conditions of salt chambers. With great respect to the Himalayan sea salt lamp, I have to say that we cannot extrapolate the pilot results from haologenerators to a hunk of Himalayan sea salt lit by a 100 watt bulb.

Are Himalayan Salt Lamps Safe?

This is a very reasonable question. Is it safe to have a piece of wet salt so close to an electric source? Is it safe and hygienic to have a trap for dust and microparticles sitting on a desk?

If the lamps really do function as dust magnets, then how do you clean the lamp? What is the lifespan of a lamp? How do you safely dispose of the lamp once it past its expiry date?Great questions to which there are no good answers. There is nothing in the published literature on the safety (or lack thereof) of these lamps.
This is where it is difficult for people like us who want to make sound decisions which are evidence based. There is nothing to help us know if salt lamps are safe. Common sense would suggest that the lamps probably don’t do anything useful that would make them worth the hassle.

The Randomised Control Trial

Medicine only recommends treatments that are proven to work and which have an acceptable safety profile. The gold standard for any intervention to be accepted into medical care is the randomized controlled trial. Here is how a randomized control trial works:

People who have a particular medical condition are enrolled into a study. They are fully informed about the study and give their permission to participate in the study. Patients are then randomly allocated into two groups. The idea behind the randomization is to make sure that there is no bias which could affect the results of the study.

One half of the patients usually get the intervention of interest and the other half get a placebo or dummy treatment. Neither the doctor nor the patients know which patients get active treatment or placebo.The patients are followed up and the outcomes of the two groups are compared. If the treatment group do better than the placebo group then the treatment is deemed to be effective.

The treatment is rejected if the treatment group does worse or does the same as the placebo group.

There are no randomized controlled trials looking at Himalayan sea salt for BP which means that we cannot and should not recommend it to people.

The Bloggers Responsibility

The internet has completely changed the way people get their health information. It is terrible to see patients like this lady doing badly because they believe some misinformation that is posted online. We all need to be really responsible for any information that we post online. We even need to be responsible when re-tweeting , re-pinning or sharing on Facebook.

Not only should the information be accurate, it also needs to be unambiguous. It needs to be clear to people across a wide range of literacy and educational backgrounds. It needs to be updated as new information emerges. We also should post disclaimers saying that the health information posted online should not replace regular medical advice.

I checked out the blog that this lady had read and found it confusing myself. I wonder if the blogger meant that sea salt was better than table salt for BP control as opposed to recommending taking sea salt as a medicine but it was not clear. Like many health related blogs I found no disclaimer which just adds insult to injury. Even bloggers should be held accountable to the Hippocratic principle of ‘Above all else, do no harm’.

Luckily my patient is doing fine and my little Himalayan sea salt lamp is back in my home.

Conclusion: There are no studies on Himalayan sea salt which means that we cannot and should not recommend it. We need to be really careful when discussing any treatment to make sure that we separate out folk cures from bona fide evidence based interventions. The internet has given us a new generation of Dr Bloggers who should take this privilege and responsibility seriously.

12 Comments Himalayan Sea Salt: Misunderstandings, Health Risks, Dangers?

  1. Palmira Scaddan

    Tom Goyetche posted that pink Himalayan salt lamps are
    Toxic, to get rid of them. Now there are restaurants covered in that salt n people stay in those rooms breathing in their toxic air. He provided chemical analysis
    And as laymen really doesn’t say it’s good or not just
    Chemical charts which show the compounds that rock
    Salt have, which I cannot decipher whether good or bad.
    Having salt lamps it worries me. Can u shed light on this

    1. Gemma

      Yes I follow Tim Goyetche and he does provide evidence that the lamps are toxic so I’ve chucked mine out. I didn’t use it for health benefits, I just liked it. Not worth the risk imo.

  2. Dixie Cook

    anything natural is worth a try. My mom almost died and has had long term negative heatlh effects since taking Bencar a nationally prescribed high blood pressure medication..She is in class action law suit, because of it.

    1. Thomas Pirelli PhD

      I think what’s tricky Dixie is that lots of people assume that “natural” means “safe”. But it doesn’t. Lots of apparently “natural” things can be harmful (our article on Bee Venom Therapy is a nice example. Bees are from nature but letting them sting you can have terrible effects).

      1. Deborah Jackson

        Even sadder for the bees as they can only sting once then they die. Sounds rather cruel to me.

    As an asthmatic I noticed a difference right away with a salt inhaler, within a few days I did not need my medication at all which was amazing, but I still take some just incase.

    It has changed my life honestly, I know there is not a shred of evidence, but there sure is allot of happy Asthmatics out there and I’m one of them.

    I can’t speak for science, but when my body started breaking down 2 years ago with what Seemed to me to be dehydratiin symptoms, adding Himalayan salt to my water is what brought me back to feeling normal. I was drinking plenty of water. But one day I woke up with red eyes, parched throat, and I started getting cramps. This persisted daily. I had to experiment until I found something that worked. It took abou 100 oz of water per day to alleviate the symptoms. I tried cutting back so I could use the minimum, but recently increased the amount again because symptoms were returning. Then I noticed my feet stopped being cold. I had been wearing 3 pairs of socks to bed and at least 1 pair when I was awake. So, I can’t explain why Himalayan salt is good for me. But it helps me to be able to function. I am able to sleep without socks again. My eyes don’t hurt. I am not getting cramps and muscle spasms.

    I decided to test Himalayan Salt 1 tsp in a gallon of distilled water which should return it back to 752 ppm. The reason? I went to Poland and the water tasted so flipping good and so did the mineral sparkling water. The tap water at my house isn’t very good come and to it because it tastes so hard and apparently has too much fluoride? (Not sure) I think it taste a tad like salt but sadly tastes better then my tap water. :,( really I am going to do more research. But appreciated this article!

    The salt is pink from iron. Can it add iron to your diet?

    Related question- is low sodium salt safe?

    Comment on treatments that restore health-if you have a virus and the effects diminish as your body removes it-but you don’t just let it run its course, instead you take something- an antibiotic, garlic, orange juice, dissolve an aspirin in water, apple cider vinegar, eat honey comb, so on (all things I have seen tried) and you get better-you then think your treatment worked, but the virus would have resolved anyway. (If you are not immune compromised).
    Then I go the next step and must ask- what is the likelihood that many prescribed medications with actual scientific or medical backing (esp psych meds) are viewed as “successful treatment” via a diminishment of symptoms that may well have occurred without the medication, because the individual chose also to excercise, eat nutritiously, reduce junk food and control weight, get good sleep, and reduce stress through chosen practices daily? After 2 heartbattacks caused by SCAD (and 4 stents-prior to research that advises against stents) I ditched all my “heart disease” meds as soon as I was able to start exercising again (moderately). and added favorites like spinach back into my diet as well (contraindicated with blood thinners). I avoided physical activities that could stress my apparently connective tissue weakness friable arteries. I have other signs suggestive of connective tissue disorder but am relatively healthy and no meds (AMA-told to stay on plavix for life) 9 years out.

    I want to step away from what you have posted and give you some food for thought.

    As a person who spent years seeing specialists for a rare disease along with severe food allergies, please know I mean it when I say that I sincerely hope that you never have to find out the hard way that medical evidence isn’t always important when something actually helps a person. I understand what you are saying- don’t try something just because it’s a trend. Right.

    I spent years going to specialists, taking steroids, trying experimental medication, participating in studies with leading hospitals- guess what they said at the end of the day after years I’d poking and prodding me like a science experiment to no avail?

    “We don’t know what to do. Please try to ease your symptoms homeopathically if you can. There’s nothing we can give you to help”….

    So then came the bone broth, probiotics, supplements, hymalian salt sole, meditation, hippy dippy new age nonsense. Guess who isn’t sick anymore? Guess who doesn’t put faith in modern medicine ALONE anymore?

    Please relax. The energy you put into shattering peoples homeopathic experiments… when having a PHD you should know and fully understand the placebo affect and the benefit and positive thinking anyway- you could have probably found an actual positive, helpful idea instead.

    1. Nathan

      Ashley, great points especially about being positive.
      But the author is not “shattering peoples homeopathic experiments” in any way. She is simply stating the facts about the issue and exhibiting no disrespect to anyone. She is only reporting on what is known and not known and I am very confused where you possible came up with that accusation.
