It’s nearly impossible to live a purely “clean” life when it comes to harmful chemicals and ingredients in your home or in your food. You CAN make positive changes and make better choices though and that’s what Mariah and I have been doing since we were married and especially since we have little ones. It’s important to never stop learning about what affects your health and about improving the safety of your loves ones. You may have seen last week on Facebook that we both chose a healthier and more natural option of deodorant and we LOVE it. One of the other changes was to purchse a water filter for our shower. After a lot of research I picked one that was reasonable in price, had the best consumer reviews, and filtered the most harmful chemicals. Here are a few reasons why you should use a shower filter immediately! Pay close attention to #4! Here’s the one we bought (click on the image to see all the stages of filtering it provides:
1. We May Absorb More Chlorine Through Showering than Through Drinking Water
It may seem counterintuitive, but showering in chlorinated water can lead to more chlorine absorption than drinking chlorinated water. This is because we typically shower at warm temperatures, which makes absorption easier and because this water is coming in contact with such a large area of the body. In fact, research shows that the chlorine in shower (or bath) water can easily enter the bloodstream as it has a low molecular weight and can easily pass into the body.
Chlorine can also interact with other matter in the water to form harmful byproducts like trihalomethanes (THMs). One of these trihalomethanes is chloroform. Thankfully, it isn’t found in high enough amounts in shower water to cause that severe of a problem, but it certainly isn’t good to come into contact with regularly.
Warm air and water also open lungs, making inhalation of these chemicals easier as well. In fact, a study found a higher than normal concentration of chloroform in the lungs of study participants after a warm shower.
Chemicals absorbed through the skin can enter the blood stream quickly and have a tremendous impact on the body. This is great when it comes to things like topical magnesium that we want to enter the body quickly and in large enough amounts, but not so good when it comes to harmful disinfectant byproducts. This study even showed a greater lifetime risk of cancer and other problems from bathing or showering in chlorinated water than from drinking it.
2. Shower Water Releases Chemicals into the Air in the Home
There are some obvious offenders of indoor air-pollution:
Scented candles release harmful fragrances and paraffin into the air and are a major source of indoor air pollution. Air fresheners and cleaning chemicals are also major offenders, but many of us don’t realize that shower water is also high-up on this list!
The heat of shower water can cause chemicals to vaporize and be released into the air at higher amounts than they are even present in the water itself. The EPA found significant and detectable levels of THMs and other byproducts in indoor air as a result of bath and shower water.
3. Chemicals in Shower Water may Cause Harm to the Skin Microbiome & Irritate Skin
As I already mentioned, the microbiome isn’t limited to the gut. While the importance of beneficial bacteria in the gut is becoming much more well known, there are lesser known “biomes” on the body, including the mouth and skin.
Logically, showering in a disinfecting agent like chlorine that is chemically tested to reduce bacteria in the water may have a tremendous impact on the skin biome. Many of the effects to the beneficial bacteria are not visible and many people don’t seem to have any noticeable affects, though some experience dry skin, eczema or irritation.
4. Chemicals Present in Shower Water are Linked to Cancer & other Health Problems
As a follow up to the first point, some of the chemicals present in the water supply have been linked to various types of cancers. These chemicals can be problematic enough when consumed in water but are even more harmful when inhaled or absorbed through skin. Chris Kresser explains:
“Research conducted on the health effects of chlorinated drinking water have demonstrated a variety of toxicity issues. Several studies have found that communities using chlorinated or chloraminated drinking water have an increased risk of bladder, kidney, and rectal cancers. (4, 5, 6) THMs from chemically treated water have been associated with a variety of poor birth outcomes, such as spontaneous abortion, birth defects, and low birth weight. (7) Chlorine and chloramine vapors are associated with greater risk of asthma, and may damage the mucosal lining of the respiratory tract. (8) Free radicals in chlorinated water have been linked to liver malfunction, weakening of the immune system and pre-arteriosclerotic changes in arteries.”
(9) and Food Renegade points out a more specific link between chlorine and breast cancer:
“Breast cancer, which now effects one in every eight women in North America, has recently been linked to the accumulation of chlorine compounds in the breast tissue. A study carried out in Hartford Connecticut, the first of it’s kind in North America, found that, “women with breast cancer have 50% to 60% higher levels of organochlorines (chlorination byproducts) in their breast tissue than women without breast cancer.””
Of course, correlation does not equal causation, but in this case, the evidence is strong enough to at least warrant caution and further study. At the very least, I find it worth taking precautions against easy-to-eliminate sources of chlorine exposure by using things like drinking water filters and shower filters.
5. Chloramines May be Even more Harmful than Chlorine
Another chemical often used in the water supply is chloramine, a mixture of chlorine and ammonia. As you may imagine, it has its risks as well and may be even more irritating to the skin and lungs that just chlorine.
Unfortunately, many filters that remove chlorine do not easily remove chloramines, so it is important to research options and address both chemicals when considering shower filters.
Shower Filters: Bottom Line
Filtering shower water is one simple and relatively inexpensive step that can make a big difference in reducing chlorine and other chemical exposure in the home. Some people seem to be much more sensitive to chlorine and notice the effects more readily, but these chemicals affect all of us on a cellular level.
Using a simple shower filter or bath dechlorinator is an easy way to remove chlorine and other harmful chemicals in bath and shower water.
