chlorine allergy symptoms and treatments

Many people experience annoying skin reactions when they spend a few minutes in a new pool and this can be categorized as chlorine allergy or “chlorine sensitivity” to be a little more practical. What usually happens when you have an allergic reaction to chlorine is your skin will become irritated and itchy much more easily than other swimmers.

For others, you may have an itchy face, sneezing or runny nose when you swim in a new pool. The most severe symptom for chlorine allergy is going to be an irritated and itchy rash. Something like this is definitely likely to deter you from swimming in new pools.

The fortunate science behind chlorine allergy is that it is something that can be quickly treated with a topical on the skin. There are also ways to determine if a pool is treated with chlorine or another alternative chemical.

In addition to pools, chlorine is also present in the water supply that goes to peoples’ bathrooms and drinking water supply. If you think that your immune system is suffering due to chlorine allergy, read on to learn about how to recognize chlorine triggers in small amounts and how to treat and avoid the symptoms entirely without the need for anxiety.

Different Kinds of Chlorine Allergy Symptoms

For many, it may seem like you can go in some pools, but others give you very uncomfortable symptoms ranging from a skin rash to your airways closing. This may give you some anxiety when going in your friend’s new pool, a water park, etc.

What’s worse? Telling everyone you’re afraid of water because it might cause an allergy or telling them you don’t want to take your shirt off?

Well if you develop a crusty body rash after swimming, it could be the former.

If you have an allergy to chlorine, the different systems of the body may react in ways depending on the unique type of person that you are. Although a fatal reaction is extremely rare, an allergic reaction to chlorine can cause moderate to severe discomfort.

There are different ways that chlorine can enter the body: direct skin contact, entering through the eyes, inhaling through your lungs, etc. Contact with chlorine will affect different parts of the body in unique ways.

Chlorine Allergy Skin Symptoms

The skin is the largest organ of the body, so it’s very easy for it to come in contact with chlorine. Chlorine allergy symptoms on the skin can manifest as a scratchy rash or eczema. These patches can appear on the arms, knees and in-between the legs.

It is likely that you will experience uncomfortable itching and peeling on these affected areas. The skin may be so dry that lotion and ointment may not do anything for you.

Since many laundry detergents use chlorine bleach as a cleaning agent, you may find yourself having itchiness on your body that can’t be explained throughout the day. This is likely because the small layer of chlorine that is still present on the surface of the clothes is enough to irritate your skin. (Source)

If this is the case for you, try to use a detergent in your washing machine that is chlorine-free.

Chlorine Allergy Eye Symptoms

Irritation of the eyes is the easiest and fastest way to tell if you have a chlorine allergy. Once the chlorine enters your eyes from the pool, you may feel itchiness of stinging at first.

After a few minutes, your eyes will get red and puffy, just like you’d expect from a lot of others at the pool. Fresh water will not do this to your eyes and this may be a common misconception. If your eyes get red and itchy at the pool, you should definitely avoid contact with the same water source.

In many cases, eyelashes can fall out and excessive itching or burning can occur in the eyes. If this if the case, avoid rubbing your eyes because this can make the allergic reaction much worse by spreading the chlorine around.

The best way to soothe your eyes after a chlorine allergy reaction is to apply a cold compress with an ice pack. This should bring down a little bit of the redness and the swelling.

Respiratory Problems from Chlorine Exposure

Chlorine is a very complex molecule in chemistry that doesn’t seem to know what it wants. It chemically jumps around, bonding to other molecules, and changes states of matter quickly under slightly changing environmental conditions. (Source)

This means that chlorine can turn into a gas, even at the pool. If you are allergic to chlorine and you are nearby a pool of water that has been heavily treated with chlorine, then you can simply breathe in and get lung irritation from the chlorine molecules in the air. This can cause tightness in the chest, wheezing, shallow breathing, sneezing, or coughing.

If these symptoms are familiar, then you definitely have immune reactions to chlorine. A full-blown asthmatic reaction can occur in rare cases and a doctor should be contacted immediately. This only happens to a very small percentage of the population, however.

Digestive Symptoms from Chlorine Allergy

Of course, another way of ingesting something is through your mouth and into your digestive system. Sometimes you may swallow pool water by accident and you could experience an allergic reaction this way.

Your digestive system can also be affected by chlorine fumes being inhaled, but this usually happens when the concentration of chlorine gas is very high. (Source)

Symptoms that can result of this include:

  • Dizziness
  • Delusional feeling
  • Acid reflux
  • Nausea of vomiting
  • Headache

Since children are more likely to swallow pool water by accident and they have more sensitive bodies, they may be more susceptible to these kinds of symptoms.

Effective Natural Chlorine Allergy Treatments

If you have a chlorine allergy rash, then the best way to treat it is to apply a natural antioxidant moisturizer.

antioxidants for chlorine allergy treatment

This lotion is designed for swimmers with chlorine allergy and incorporates vitamin antioxidants that you need for your skin after a swim.

The science behind this is to consider how chlorine works as an element and molecule. The chlorine atom has 7 valence electrons, which means that it wants to get an electron from any possible source so that it can be stable. This is unique for an atom, except fluorine is the same way. (Source)

Therefore, chlorine strips the natural nutrient content of your skin by damaging skin cell’s oxidation level. To counteract this action, you can try to do the opposite of oxidating your skin cells, which would be called “reducing” them.

The best way to do that is with a natural antioxidant moisturizer that incorporates vitamins C and E.

Chlorine works in the same way when it is absorbed into the body. So consuming antioxidants through food may be healthy for you after a chlorine allergy reaction.

My favorite and most effective antioxidant drink is matcha green tea. This green tea powder makes you feel amazing and helps me heal after an allergic reaction.

Chlorine can be found in small amounts from other sources

Obviously pools are going to be the thing that comes to mind when you think of chlorine exposure, but it is also going to be found in your house’s water supply. Most major governments also disinfect the water supply by adding chemical chlorine, which kills pathogenic bacteria.

Chlorine usually evaporates itself over time if it is not covered in water, but sometimes the water is contained after it is disinfected and the chlorine remains until it reaches your house.

If you have ever gone to someone’s house and their water smelled like a pool, then the chlorine is still present in the water after disinfecting,

This also means that there is chlorine in your shower water. At high temperatures, chlorine more easily turns into a gas. Therefore, the high temperature that heats your shower and bath water is constantly generating chlorine gas that is contained until you turn on your shower or sink.

And we discussed how chlorine in the air can damage your lungs and cause asthma in non-asthmatic people.

How to get rid of chlorine in water

If you have determined that chlorine allergy is causing these annoying symptoms when you are near a pool, have an extended hot shower, or drink your unfiltered tap water, then there are some methods to getting it out.

The only way to get rid of chlorine from your water is by letting it sit uncovered before you use it. You can leave a pitcher of water without the top on your kitchen counter and cover is with a thin cloth overnight. When you wake up in the morning, most of the chlorine should be dissipated from the water.

  1. I have had a chlorine allergy for about 20 years. It began when I experienced migraine headaches which lasted for about 3 to 4 days and I realized that I never got them when I stayed at my cottage which has well water. As a teacher I would take my classes to an Ottawa swimming pool for lessons and I always became sick by just being in the pool area not even going in the water myself. I would become disoriented and even pass out from exposure. I have filtered my drinking water with a Brita filter for many years and that has always really helped immensely but I recently was away from Ottawa for 6 months and when I returned I began having severe itching all over my body. Again when I went to my cottage my itching ceased so I am now looking into a whole house water purification system which is effective in blocking chlorine and at the same time does not break the bank. Anyone out there with experience with chlorine allergy and water systems please contact me .

      Thanks a lot for visiting and sharing your experience with chlorine allergy. That sounds like a very severe case of it. Do showers bother you and do you have a filter in your showerhead that filters the chlorine from tap water? Also does drinking tap water bother you because there are small amounts of chlorine in most public water supplies.

  2. I have a chlorine allergy that causes severe symptoms. I can’t go in buildings that have municipal water because of the chlorine vapor in the air.
    It gives me such severe wheezing that it’s very similar to anaphylaxis.
    I also get nasal and sinus polyps, which last months from a short time of exposure to the gas.
    Some cities that also use ammonia in the water, I can’t even walk outside in. (Chloramines)
    I have to live out of town, on well water. (Good well water is cleaner than treated city water, so no trouble there)
    It’s just incredibly hard to find houses to rent with Wells.
    The allergy also causes my joints to swell and a whole world of digestive issues… And that’s from the vapor, not from touching the water.
    I lived in town at one point and couldn’t be in the house while the room mate took a shower and every time I ran the tap, I got an instant nosebleed.

    Chronic exposure caused this. I used to be fine. Started getting sick when I moved to town, but had no idea what was causing it.

    Even the whole house filters aren’t enough.

    Ozone water disinfection is so much better and safer. Bleach causes cancer, we know that… So we really shouldn’t drink it.
    People say it’s a small dose, yet it bleached my dark brown curtains on a dosing day… It fluctuates significantly between dosing schedules.

    I know someone else that can’t breathe at all when she tries to take a bath or shower…
    I think a lot of childhood asthma is from chlorine.
    Kids are always on the floor too, and are short, where the gas builds up.

  3. Dear anthony,
    2 years ago i have set a chlorination system to disinfect water, i put calcium hypochlorite tablets into water then the water passes by a carbon filter to remove the chlorine. Several months ago i bypassed the carbon filtet by mistake and chlorinated water entered the house. I washed my clothes with it by mistake in the washing machine. I stopped using the chlorination system. I tried to clean the washing machine but all clothes and items washed in it causes burning on touch inspite that i washed them several times with clean water. Now everything i touch at home causes burning sensation

      Hey there,
      I want to ask you why you would install a chlorination system to disinfect your water. In most third world countries, this addition of chlorine is already done by local governments. Are you in an area where infection of the water supply is common? Also, are you allergic to the chlorine? Let me know as soon as possible!

  4. It’s interesting to read about some of the symptoms of the allergy to chlorine, especially after swallowing pool water. We might be getting a pool soon and I want to ensure it’s safe for everyone. Having the kids tested for a chlorine allergy could help make sure we get a salt-water pool if they are or that we take the proper precautions not to let it affect them.

      You’re right. There are alternatives to chlorine for your pool if you have chlorine allergy. Some use stuff called Bacquesil or others, but high amounts in your pool is possible anyways because chlorine is found in tap water to begin with. Especially in indoor pools, chlorine can be found in very high amounts in the pools. Chlorine allergy sufferers should avoid these.

  5. Pools bother the hell out of my skin and I always wondered if it was chlorine or something else in the water. But now I know it is an allergy to chlorine. I have found that the antioxidant lotion really works wonders for chlorine allergy

      If you can’t go in indoor pools, you probably have chlorine allergy. Chlorine allergy sufferers should try a lake or a beach instead.
