The Dangers of Chlorinated Pools and How To Protect Yourself

by Sarah Green LivingComments: 157

By Sandrine Love, of Nourishing Our Children and Nourishing Ourselves

Another topic to explore as we head into the summer season is chlorinated pools.

Chlorine is popular because it handles the three main jobs in keeping a swimming pool clean: It sanitizes (kills bacteria and germs), oxidizes (controls organic debris from perspiration and body oils), and deters algae. The chemical is unpopular, however, because it has a strong odor, reddens eyes, causes allergic reactions in some swimmers, and is a known carcinogen – meaning it has been linked to cancer!
Chlorine absorbs into your skin. Too much exposure to chlorine has been linked to major health problems including reproductive disorders and even birth defects.  It can cause your skin and hair to dry out and over time too much exposure can even cause wrinkles.

Editor’s Note: Have you ever wondered why Olympic swimmers seem to have so many wrinkles at such young ages and most of the men start losing their hair so quickly?   Could it in fact be caused by overexposure to chlorine for so many years and so many hours every day?  Perhaps so.

When chlorinated pools are indoors, toxic gases such as nitrogen trichloride are released, which can be very dangerous. When we breathe in this gas it can cause severe damage to the lining of the lungs which could lead to respiratory problems or asthma. This toxic gas can be harmful at any age yet it poses the most risk to elderly people and small children.

So while chlorine used to disinfect swimming pools is widely recognized as a health hazard, not everyone has access to the ocean or a lake, or pools treated with ozone, ionizers, bromine, silver-cooper, or other alternatives which can frequently be much more expensive.

If you or your family members do choose to swim in chlorinated pools, some recommendations I’ve read are to:

1. Swim in an outdoor chlorinated pool. It is much safer due to the fact that the majority of the toxic gases are eliminated in the air.
2. Swim in chlorinated pools on occasion only.
3. Shower immediately before and after with a natural soap.
4. Drink plenty of non-chlorinated, filtered water beforehand so that you are well hydrated.
5. Consider wearing a mask and snorkel to shield your eyes – and even a wetsuit, if you are willing to go that far!
6. Get fresh air afterward so you don’t continue to inhale the fumes, and can clear your lungs.

Why shower immediately before swimming in a chlorinated pool?

Julie Deardorff explains in her article published in the Chicago Tribute, “Another important reason to shower is that our bodies generally contain residue from consumer products, including perfume, make-up, body lotion, shampoo and sunscreen.

When the chemicals used to disinfect the pool mix with organic matter (sweat, hair, urine) or nitrogen-rich substances (commonly found in consumer products) it can create a more toxic agent, said Michael Plewa, a professor of genetics at the University of Illinois whose new research has linked pool chemicals to health problems, including asthma and bladder cancer.”

Red, burning, itchy eyes and skin?

What I’ve read is that the presence of chloramines can cause reactions such as red, burning, irritated eyes: Chloramines form when chlorine reacts with ammonia. Ammonia enters the pool through sweat and urine. It is important to teach children not to urinate in pool water [even though it is chlorinated].

Also, showering before swimming can remove excess sweat that interacts with chlorine. My understanding is that if the sweat is on your skin, and hasn’t been rinsed off first in the shower, the chlorine will interact with the sweat on your skin as you enter the pool, and may result in some folks getting itchy skin.

So, what do you think – do the benefits and joy of swimming and playing in a pool out weigh the risks of chlorine?

    Thanks for this article, the chlorine is a huge problem and it’s plagued my life.

    I’ve been swimming for close to three decades and my sensitivity to chlorine actually increased over time to the point where I developed eczema. I also don’t want something to mask the smell, I needed to wash off the chlorine. In my research to allow to me to swim, I found Swimmer Soap, it’s an all natural bar soap. I’ve used it for a few months and it definitely washes out the chlorine and my eczema has slowly faded away. I think it’s more important for children to properly wash off chlorine due to long term effects from cumulative exposure. You don’t want to address the issue when it’s too late. Hope this helps.

    i started swimming at Walden Pond in Concord Massachusetts this past June. This experince has reminded me how many hours I played at the beach as a child. and realized I had denied myself the experience for years. So now the winter is upon us and I have joined the local YMCA., mainly for the pool. I have swam twice, the day I joined and today, the day after. I have always had issues with my skin, I get itchy in different spots, for no apparent reason nd at no particular time or during or after an activity. Needless the say, I usually dont shower everyday because of this. Now, I need to take a shower prior to my swim, then after to get that horrid smell off my skin. Today, I even took a shower once I got home, meaning I took three showers today and swam for about a half hour in a heavily chlorinated pool. I am itchy. I know all the suggestions, and I do them to keep hydrated. If I could still swim at the pond, I would, believe me. I actually am not looking forward to depending on an indoor pool for about half the year. I felt the chlorine effecting my breathing, when water went up my nose, it burned and I can tell my body hates it.

    I would actually suggest an ozonator(ozone generator) because it would totally eliminate the use of any of the above mentioned chemicals and also provide a much better experience. Earlier, there were very few manufacturers of such products and the reliability was an issue but off late there are some good products with greater reliability.

      I have found the best solution from a fabulouscompany called enviroswim in Australia. I have had the pool for a year now and can honestly say buy one and save money aswell as eliminate the dangers of chemicals. All you need to do is top up the Acid and every two years spend $70 on a new set of diodes. It is like swimming in a stream or lake. Chlorine is so 30 years ago and it is time we all woke up to the fact that pool shops would no longer be required. Unfortunately chemical companies manage to offer large incentives probabl as far as local governments to keep the chlorine pouring in. It’s time everybody said no to this filthy killer chemical.

    My son always felt sick after swimming in chlorine, until we learned he should shower beforehand. Besides clearing away sweat, I think it also saturates the skin with less-chlorinated water, so he doesn’t absorb as much in the pool.

        Exactly right John, not to mention e. coli and some other very nasty little bugs. For all the inherent dangers with a pool, it is the very safest place for your family to swim. No rip currents, jelly fish, amoebas, hidden rocks or discarded traps, etc. I also would like to add, that the water you shower in typically has the same amount, or more, chlorine than a pool.

      I’m finding that there is a lot of uninformed and unqualified opinion on the internet. A friend just told me that you have to shower after the pool because you have to get the Cl out of your body. I can understand if your hair is still wet there’s still Cl there. But if you’ve dried off, all the Cl on your skin would already be absorbed into the skin and a shower would not remove it.

    I have found that drinking a lot of water and doing an activity like running that causes you to sweat a lot after swimming helps to get rid of the chlorine that you’ve absorbed through your skin. Although showering does help, I’m sure you’ll notice after a swim that you’ll still smell the chlorine when you turn on the shower the next day. Sweating it out ASAP after a swim is the truly the best way I’ve found to get it out of your body.

    Julie, in my experience many pools in the US have a sign that says you must shower before you get in, but almost no pool enforces this rule. I’m not sure if I’ve ever known anyone who really consistently follows this pseudo-rule or tradition or whatever it is. I’ve personally always thought it was an incredibly odd rule. And now that I’ve learned about how dangerous our efforts towards sterilizing our environment are I’m all the more convinced that it is just an extreme version of the mental health disorder furthering our societies germ phobia.

      Hi Sheril. I, for one, always shower before I get in. One benefit for this showering rule (law where I live in upstate NY) is that it minimizes the amount of chemicals that are required to maintain the proper pH level in the pool (7.4 to 7.6). Allowing the pH to go too far one way will allow all kinds of bad things to thrive in that water. Your stank, oil and sweat all contribute to this pH balancing act. Teaching kids to not piss in the pool (to the point where they actually don’t, which requires parents paying attention and following up) will help this. Every time a little one drops a baby ruth in the pool, we (the lifeguards, hi there) have to (literally have to) clear the pool and shock treat it…. meaning we dump a crap load of chlorine (or something else, if using bromine in place of chlorine) to assure that any bugs in the poop are killed off. 45-60 minutes later, everyone can go back in. If three little ones crap 3 times in a day, that’s bleach blonde hair for everyone. I really like the 2 pool system, where little ones are not allowed in the big pool. To make things worse, any of us that are competitive swimmers (hi there) who need one of these pools to swim a workout in are going to sweat way more than we need to, because the pools are usually way too hot for this type of thing. More sweat, more chemicals. Again, 2 pool system would help as the little ones, and the old folks who do not intend on moving enough to stay warm (???) can be in the little warm pool. The pools that you guys are visiting are probably public pools where people come in, not really giving two craps about what they leave behind because they don’t have to deal with it (or are ignorant of these things), and are, here it comes, poorly run by people who have absolutely no business running that which they do not understand. As for the Chlorine or bromine what ever is in use there, I carry a small spray bottle with water and some powdered acsorbic acid (Vit C) and when I take my post swim shower, I soak myself with that, rub it in, wash as normal and no pool smell, no itchies. Since it is nothing more than Vitamin C, I can literally spray this stuff in my mouth if I want.

Also I think the before-swim shower helps to saturate the body with water, so less chlorine is absorbed. We have a chlorine filter on our shower at home, which is good for rinsing off afterwards.

    It’s difficult for me to read this, because my daughter likes babyswimming very much (she’s 11 months old). But ofcourse, the swimmingpool is indoor and chlorinated. No options to go outdoors or go to a non-chlorine pool. I can’t teach her not to pee in the water, she’s too young. I put coconutoil on her body before swimming, and we take a shower before and after. Sometimes she swallows water, hard to avoid. Swimming is so relaxing for us both, but after reading this I’m not sure about it anymore. I live in a water country, and think it’s important for her to get familiar with water at a young age.

    Ah, Andrew your reply was like a drink of water in this desert of misinformation. I swim often and I recently started bringing a small spray bottle with water and powdered ascorbic acid (Vitamin C) to shower with after practice. No more stinkies, no more licking my arm 2 hours later and smelling chlorine, and my hair likes it much better now! I just rinse in the shower, then turn the water off, spray myself down and scrub it in, then shower like normal. As for skin appearance, since beginning juicing and eating one avocado daily, along with swimming, I actually have people tell me I look YOUNGER. 1.5% of your body weight is Chlorine. It is actually used by many processes in our bodies. GO SWIM (and take some C water with you) it will increase your lung capacity A LOT and I am sure you know what that is linked to…..

      Ascorbic acid (which is not really vitamin C) is made from gmo corn syrup and acetone. So you can feel free to get your exercise in a chemical bath and then “treat” yourself with some ascorbic acid, but I think you’re missing the point….

        I don’t know the validity of that information, but no matter, as the powder got it out of my skin. I am not going to avoid the use of chemicals as if they are all bad, simply to avoid the use of chemicals. That would be a tough call, seeing how we are made up of the stuff. Chlorine occurs naturally in our bodies and serves a physiological purpose. If it makes any difference, i decided a while back to consolidate my post swim snack and stinkyz removal routines by taking an orange in the shower with me and using some of the jiuce from that instead, but, amazingly, it gives me the same results as your empty eggshell GMO Powder ‘C’. What point am I missing, btw?

    Hi Everyone – I have done a ton of research in this area. The issue with chlorine appears to be that it stays bonded to the hair and skin long after swimming. Then, the lingering chlorine continues to damage the hair and skin, leading to damage and irritation.

    Above, someone mentioned vitamin C — I couldn’t agree more. We tested and determined that applying a vitamin C rinse after swimming completely eliminates chlorine. See for more information.

      Sitting in the steam room or sauna after swimming in a chlorinated pool, showering immediately getting out of both the pool and the steam room/sauna, really helps to eliminate most of the chlorine odor from my body. I sit in there until sweat is dripping, about 15 to 20 minutes.

    a Nutropatic dr told me “remember chemistry, Iodine works against Chlorine, so use it if in chlorine. guess i am having a chlorine/iodine war inside me. breathing this in indoor pool also concerns me – thank God i am from South Africa where we learned to swim [life saving & physical activities improve school work. WWi Germans used Chloride/bleach to destroy Brits. Histler used floride/asbestus in his death camp drinking water to subdue them before he killed them, so why are we using it??? Chlorine/bleach only one higher on PH scale – toiled/sink unclogger & we are supposed to take used chlorine.bleach to special disposal places as toxic waste! what are we doing to world water when these pools dump their water load [as in cleaning] into our world water system [the only world we have] Don’t put anything you would not drink into our water system, like down your toiled – we have enough 2nd hand drugs in it now, [we recycle all our water – you could be drinking Washington urine. look at how we are affecting life [born without sex & more] in what we have done to our water

    I am looking for a full dry swimsuit so i can swim in contaminated [chlorine/fluoride – as all are here] without being in it. either pools will change water additives or these swim suits will become popular & sell well. World Health Organization say 89% of world population are now hypothyroid & avoid peanuts, soya & CHLORIDE & FLUORIDE – HELP. where can I get such a swim suit????? water activities are good but not this & there are much better options.

    I get massive headaches from swimming in chlorinated pools. When we go on trips, of course the kids want to hit up the hotel pool, so I always try to find a salt-water (or saline) pool. They are hard to find but so worth it if you can. I don’t get headaches from these pools.

    Our own families experience with chlorinated pools:
    My youngest daughter used to vomit after swimming in chlorinated pools inside or out, public or private.
    My son gets diarrhea. Probably from swallowing too much.
    My other daughter gets candida infections externally.

    As a 30 yr. swimming pool professional, let me reassure that despite inherent danger, there is no safer place for your family to swim than in a man made pool. No rip currents, hidden obstructions, sewage intrusion, you get the picture. If the chlorine smells, causes rash, or red eyes, that is an indication of trouble. A pool free of contamination and with a balanced pH will have no odor, will not irritate eyes or skin, and normally contains no more chlorine than what you will find in your home tap water that is suitable for drinking and showering in. Dry skin is however, is a result of over chlorination and there are many strategies available to mitigate or eliminate dry skin associated with swimming in pools.

    Most swimming pools are not correctly maintained. The important thing is longer filtering which means less use of chemicals. Ph is vital too, most itchy skin and stinging eyes are from incorrect ph.

      Did you mean ionizer? Ionizers typically use one or more heavy metals such as copper, silver, or zinc any of which are toxic to marine life if let into waterways. Chlorine is highly reactive and bonds rapidly to nearly anything in the environment rendering it harmless.

      Ultraviolet and ozone are two processes that hold much greater promise.

    The good Chlorine does in pools definitely outweighs the bad. Can you imagine what toxins and germs would accumulate in swimming pools if not for Chlorine? What must be learned here is to swim in moderation and rinse off before and after swimming (Let’s face it, most of us don’t!). Many people can’t afford the more expensive alternatives. As with any thing else, too much can be harmful so you must use common sense when putting yourself in contact with substances that can irritate.

    Very interesting article. I swam competitively for 13 years, year round, and in the summer spent hours and hours in the pool even outside of practice. I never really understood the shower before you get in the pool thing–that is, unless you visably have dirt/grime on you. In my experience, you sweat a TON in the pool if you’re swimming hard enough (pulse 160 for 2 hours). You just don’t feel it as much because you’re wet. I’ve been known to loose up to 2 pounds during a swim practice. Definitely shower afterwards!

    After so many years in the pool, I haven’t experienced any of the above side effects. Both of my kids were easily conceived and are perfectly healthy. I guess something to look out for as I get older?

    Shortly after I graduated high school, I learned they switched to a bromine pool. Just one word on that: ICK! Created an almost visible grease slick on all of the swimmers. They all had really terrible acne, it clogged the filters, and it stunk. They’ve since switched back. The YMCA near us has just switched to a saline type of pool…the verdict is still out on that one. We only go there once a month or so. I guess I’m a big fan of chlorine pools.

    I remember once we went to Florida for a training trip in college around Christmas time. It was very welcome since it was -35 degrees in Iowa when we left. We had an outdoor pool to practice in and the 65 degree weather was awesome to swim in. :)

    as a holistic hairdresser and real food advocate I liken swimming in chlorine pools (for exercise) to jogging along a major highway. However a refreshing summer swim is part of the summer season for many children and adults. Chlorine is very alkaline and so are soaps and detergents – which is why you can still smell like chlorine after soaping up. What changes this is a dilute vinegar rinse (which has acidicPH and healing). You can mix 1/2 good apple cider vinegar to 1/2 water. Pour this mixture thru your hair and over your skin. You can also put it in a spray bottle (don’t let the solution sit in plastic though). Or a cup of vinegar in the bath. Let sit on the skin for a few minutes then rinse off. This can be done after a thorough soaping if you wish. Vinegar also heals sunburn overnight. Good organic vinegars like Braggs work better than cheap supermarket vinegars.

    Just wanted to add that chlorine, like bromine, gets absorbed by iodine receptors, thereby blocking full absorption of iodine. So if you swim in pools a lot, you will need to greatly up your iodine intake.

    Also, if you are already getting adequate amounts of iodine, less chlorine will be absorbed.

    Hi, I just wanted to share my experience. We inherited an above ground pool when we moved to our new home. Last year I bought the USA-made Floatron (available on their website or Amazon) for less than $300. It is solar powered copper ionizer and it works fantastic!! We balance the pool in the spring with chemicals, but then the Floatron is perfectly capable (even in cloudy Michigan!) of keeping the pool crystal clear all summer long with only the barest minimum of chlorine tablets used occasionally. It feels like swimming in rain water, with no nasty smells or irritation of my skin or that of my young children. I highly recommend this product.

    Our family went on a mini vacation in March and my daughter, Kyra, was the only child who has problems with swimming in the indoor pool. It ruined her hair.

Because the pores are closed, it won’t drink aany of the pool water. I am going to assume it does the same thing with our skin. Then they need to wash down real good after swimming.

    I am in a pool every day. Lap swim at least a mile every day in an indoor pool. I don’t like the chlorine exposure. That said, I feel that the benefit that I get from being physically fit and not tearing up my joints and bones in the process FAR, FAR outweighs any detriment I get from the chlorine. I do shower immediately with Dr. Bronners upon getting out of the pool. I don’t wait until I get home. And I drink raw milk kefir every day to repopulate any gut flora that may get killed off from the chlorine. Once again, as with everything in life, you have to figure out what’s best for you. I know that for me personally, I would not be in as good a shape as I am now without the swimming. I am 55 years old, fit and healthy. Swimming is a wonderful sport and fitness activity that can be enjoyed and engaged in literally from cradle to grave!

      I’d have to agree-swimming is an amazingly good sport for you. It’s actually the 2nd best sport you can do…even above cross country skiing. Love it!

      Just a side note, I used to work at a swimming school in as part of the training we learned the dangers of accidental drownings. Children can drown in as little as 2 inches of water–buckets, puddles, toilets, bath tubs, pools, lakes/rivers. It is SO important to teach your kids how to swim (and how to climb out of a pool), more important (in my opinion) than subjecting them to chlorine for an hour a week. Where I live, there are not very many options for swimming other than chlorinated pools. By all means search out natural bodies of water, but whatever you do teach your kids how to swim. A 5 year old has a lung capacity of a 20 oz bottle of soda and when empty can fill with water in seconds. (Experiment at home by holding a bottle upright under water without the cap…scary.)

    I asked our naturopath this very question a few years ago. His response, which I thought made a lot of sense, was the exercise and sunshine are so good for you and outweigh a lot of the risks. He said, “no” to indoor swimming which we have avoided since then. He also recommended that I wet my boys’ hair with spring water before they get in. Thus, their hair is already wet and won’t absorb as much. Secondly, he recommended we “lube up” with cocoa butter to give skin lots of moisture and an oily barrier. I think it has really helped, especially my browner skinned boy who tends to be dry anyhow. Not to mention, both boys smell edible like hershey chocolate bars. I thought that this was excellent advice and have followed it ever since. We swim approximately 2-3 times each week over the summer and follow this protocol to good success. Of course, showers as soon as we get home. Hope this is helpful to someone else as well.

      I have a question. I’ve learned that I should wet down the kids and myself before getting into the pool. What about sunscreen? Do you put it on before the showering that you do before getting into the pool? Is this a dumb question (it’s late).

      June 21st, 2012 11:32 pm Reply
      • Sandrine Hahn

        I don’t think it is a dumb question at all! The truth is, that according to the information I gathered, the whole point of taking a shower before the pool is to rinse off all of the lotions and potions from our bodies – so that we enter the pool clean.

        “Another important reason to shower is that our bodies generally contain residue from consumer products, including perfume, make-up, body lotion, shampoo and sunscreen.

        When the chemicals used to disinfect the pool mix with organic matter (sweat, hair, urine) or nitrogen-rich substances (commonly found in consumer products) it can create a more toxic agent, said Michael Plewa, a professor of genetics at the University of Illinois whose new research has linked pool chemicals to health problems, including asthma and bladder cancer.”

        So I think sunscreen at any point would not serve based on what I read above. I suggest that kids swim for a limited time in the pool without sunscreen if the pool is outdoors and chlorinated.

        After the pool, we are instructed to shower to rinse off the chlorine. Perhaps at that point, if they remain pool side, that would be the time to put on sunscreen, or just cover up.

        • Rose

          Well, your answer was what I mostly expected. That is we should not use sunscreen because it is a lotion, which must be one of the nitrogen-rich substances you described.

          Unfortunately, my children and I are pretty pale and will burn in about 20-30 minutes of mid-day (pool hour) summer sun.

          For me, the knowledge about the dangers of chlorination creates one of those situations where you have to weigh the costs and benefits. Summer pool time holds lots of great childhood memories for me, and my children really love it. We usually go to the city pool for about an hour, about three times per week. This is one of the highlights of summer for my kids. We aren’t afraid of lakes, but the nearest one is about half an hour away, and I don’t feel comfortable taking so many little ones by myself when my partner is working.

          Anyway, for me, this topic will remain on the back burner, and perhaps one day I will change my mind or think of a better solution. :)

          Thank you for the information. I wonder also if you have any source information that you could share?

    Sarah added the piece about olympic swimmers with wrinkles and hair loss after I submitted the article to her. I have no knowledge of that. I do know however that there are those who report that they do not tolerate chlorinated pools well. If I had a choice between a salt water pool or a chlorinated one, I would choose the salt water. The smell of chlorine alone is one I find offensive.

    I reduce exposure to toxins when I can. There are chloramines in the water I bathe in in the city of San Francisco, however not in the water I drink because of the Radinat Life water filtration system I have installed. I live in a 12 unit building, and so a whole house water filtration system is prohibitive, and there aren’t filters i have found that elimate chloramines In the shower. There are filters that elimate chlorine however, and I would recommend those if one lives in a place where chlorine is in the municipal water.

        My husband swam competitively throughout his childhood into the first year of college. He is 42 now with a very full head of hair (enviously so). I think it was his diet and good hair genes, not the chlorinated pools that determined the hair growth. Maybe the tight swim caps have more to do with that. Many farmers are balding where they always wear their caps, as was the case for both of my husband’s grandfathers. I’m just glad we can avoid chlorinated water now as much as possible.

      Great article Sandrine, however we have learned so much about chloramines in the past few years, I would love to share it with you. First of all, the choice between salt water and chlorine is based only on smell – salt is actually more corrosive and harmful when it becomes chloride. Salt is just site generated chlorine, and produces more harmful disinfectant byproducts than chlorine.

      Chloramines are the issue – trichloramines specifically. They off-gas and become airborne. For indoor pools, they are the cause of the “pool smell”, and yes they are harmful and corrosive. I am a competitive swimmer and had an asthma attack in a chlorine pool–I understand how harmful they are. But there is a system that is changing all of that, and it’s called the Paddock Evacuator. It captures and removes chloramines from indoor pools and works amazingly well. It brings a pristine environment indoors, where you cannot even smell the pool. Google it.

    But sometimes it seems as though we should all just live a bubble because “everything” can kill us.

    I grew up swimming at an outdoor pool every summer, almost every day. At 24 I have no side effects of which is claimed in this article.

    I’m just saying. At what point do we stop fearing everything around us and just live the best we can? I like this site and follow other sites like this, but sometimes its more of a “fear factor”. A will kill, B will kill you and C will keep you safe. So stay away from A and B and choose C.

      or better yet we can strive to live in a world where we find something to be harmful and look for a non-toxic alternative. everyone has these moments of dissonance where we feel bad about our past choices and try to defend them even though we know they weren’t the healthiest. the truth is we live in a filthy world of toxic chemicals, yes, and we are all exposed at some level whether we actively avoid them or not.

        A person can’t better any situation without first acknowledging the fact that there is something to improve upon : )

      i can take decades for cancer to develop so don’t get ahead of yourself saying you have no side effects. not cursing you to have cancer, i am just saying that it is not a good argument. if we know things are toxic, we should not be using them. period.

      Spreading information is important. It’s your choice what you do with that information.

      With as many interactions with toxins as an American has each day, it would be wise to cut some of them out. Now you know about pools and you can decide whether that’s going to be on your nix list or not.

      We’re not talking about throwing a clean and healthy hunter-gatherer into a chlorinated pool. We’re talking about us, who breath polluted air, play with plastic toys, eat chemicals, wear synthetic clothes, eat refined foods, were once probably vaccinated, and on and on and on. Modern people have some cleaning up to do.

    My chiropractor told me that chlorine can also cause thyroid problems because the body treats it like iodine.

      Thanks for that piece of information, Lisa. I had not come across it when researching this topic.

        Chlorine is a destructive halogen element. Fluorine, chlorine, and bromine are halogens that have an affinity for iodine receptors – they essentially deplete your body of iodine. Iodine is absolutely critical for thyroid health and an iodine deficiency will inhibit thyroid hormone production resulting in a low thyroid state.

        Thyroid expert Dr. David Brownstein found that more than 96% of his 5000+ patients tested were iodine deficient. As a public nutritionist I saw huge numbers of people (especially women in their late 30’s, early 40’s) who were suffering from low energy due to hypothyroidism due to low iodine. I wrote quite a bit about the chlorine and fluoride problem in my recent book entitled, “How to Heal your Pineal Gland to facilitate Enlightenment optimize Melatonin and Live Longer (The Enlightenment App).” In addition to the halogen-avoiding strategies I talk about in the book I take 225mcg of supplemental potassium iodide every day.

            Potassium is toxic. Iodine is a halogen (also toxic). Zinc will kill you. Guess what? Without them you also die. Might want to explore the consumption of potassium iodide a little closer, it is not necessarily safe.

            You’re very welcome Sandrine!

            Everything can kill you in the wrong doses poolswami, even water. Stay out of the deep end.
