A shower head water filter should reduce your exposure to THMs, but most of them don’t. THMs or trihalomethanes are a group of chemical compounds that include a number of known carcinogens. Chloroform gas belongs to the group.
Most showerhead filters reduce chlorine or chloramines, because those chemicals dry out the hair and skin. They are also common causes of allergic reactions. But, whenever any kind of disinfection method is needed to reduce bacteria or algae in the pipelines, THMs are produced. They are simply byproducts that form when disinfectants react with bacteria. https://buyresearchchemicalsonlineusa.com/
They even form when chlorine reacts with bacteria on the skin. Triclosan, an ingredient in antibacterial soap, produces them, as well. They are in the air or our homes and around indoor swimming pools. We inhale the air and the chemicals enter our bloodstream.
They pass through the skin during a bath or when washing dishes by hands. In other words, we are exposed to them in many different ways and the more we are exposed, the greater our risk of cancer. A shower head water filter can help reduce the risk, but only if it contains the necessary resins to reduce THMs.
Scientists have known about the risks of THM exposure since 1974. Ten years later, researchers published this query, “Does chloroform exposure while showering pose a serious public health concern?” The article was published in the journal “Medical Hypotheses”.
The problem with measuring the risk and answering the question had to do with measuring blood levels and controlling the test subjects other sources of exposure. It took years just to be able to accurately measure blood levels, in the parts-per-quadrillion range, so that the risks of exposure could be accurately measured.
A study published in 2000 indicated that a shower head water filter that reduces THMs is even more important than a filter for the kitchen sink. THM blood levels of participants were measured after showering, bathing or drinking a liter of unfiltered tap water. Blood levels were highest following a 10 minute shower.
As a health writer, my goal is to inform people that there are risks and there are ways to protect your health. My readers sometimes have questions about the sources that I use for information. The primary source is the PubMed.com, an online database for the US National Library of Medicine and the National Institutes of Health. A link to the study, for anyone that wishes to read it, is provided below.
In order to be sure that you are buying a shower head water filter that reduces THMs, ask for the manufacturer’s Product Performance Data Sheets. Not all companies provide them. Don’t buy from a company that does not provide the information. The filters are popular and there are a lot of “pretenders” on the market.
Trihalomethanes are not the only toxins we are exposed to on a regular basis. But, they are the most dangerous toxins that relate to the purchase of a shower head water filter. Now, you know.
