How Can Shower Water Contamination Cause Allergies?

Showering seems like a harmless activity. After all, how can something which is designed to make you squeaky clean end up hurting your body? The people who have allergic reactions to chemicals found in unfiltered shower water can assure you that showers are not always fun and games. Chlorine, a chemical commonly found in shower water, can trigger allergic reactions for certain people. Exposure to high levels of chlorine has been linked to many serious conditions, but for some the allergies themselves are serious. That is why everyone should be concerned about shower water contamination particularly if you suffer with allergies or if someone in your home has that problem.

Aside from swimmers who regularly spend a large amount of time in heavily chlorinated swimming pools, the primary source of chlorine exposure for most people is due to shower water contamination. Chlorine is put into the shower water for the same reason it is poured into pools. It is in the water because your local water processing facility uses it to remove the harmful bacteria from the water. However, shower water tends to be hot enough to create steam. Chlorine has a lower evaporation point than water. When your shower water is steaming, you are creating chlorine gas. That chlorine gas represents a troublesome form of shower water contamination.

Shower water contamination in the form of chlorine gas has been proven to be harmful to humans. Studies have shown that it can cause allergies, asthma, or even cancer. When you develop allergies to chlorine, your shower suddenly transforms from a place to relax after a hard day to somewhere which could become hazardous. As with every allergy, the exact reactions to chlorine exposure vary widely based on the individual. Some people merely start coughing excessively while others have reactions so bad they must be sent immediately to the emergency room.

Filtering your shower water will drastically lower your exposure to chlorine shower water contamination. It is estimated that nearly two thirds of the typical person’s chlorine exposure is from chlorinated shower water. By purchasing a high-quality shower filter such as those made by Aquasana, you will be able to use your shower without worrying about its chlorine levels. These filters are the best way to drastically reduce your chlorine exposure for a low cost.

  1. Can this also cause severe itching to where you bleed? I have notice things in the water and now not just myself, but the whole family and apartment complex are having the same problem with severe itching and bumps. The doctors just tell us that its a fungal infection. The only thing I can think of is the water. How do you go about getting the water tested

    • Contaminated water can lead to a number of skin irritations. In order to determine exactly what is in your water, a complete water assessment is recommended. Aquasana offers a water testing service with National Testing Labs that provides a detailed analysis on what your water contains. For more information you can call us at 866-662-6885.

  2. Okay so at this apartment complex I previously lived at I would get a lot of little red bumps only on the backs of my hands. Could this have been from Chlorine? It would usually go away in like ten minutes tops… I mean when I had put water in a cup to rinse after brushing my teeth I swear I could smell it… But I never did in the shower. And I don’t have this problem at my current apartment complex (granted I am in a different city that’s a hour and a half away…)

    • It is quite possible that you had a reaction to chlorine, chloramine or some other contaminant in the water. Chlorine and chloramines, in particular, can have drying and irritating effects on hair and skin.
