What is the first thing that goes through your mind when you see a filtration system designed for the shower?
Personally my first reaction was, why? At first I had no comprehension of the importance of filtering the water I shower in and thought it simply to be a nice luxury item. Only later did I learn that showering in filtered water is even more important than drinking filtered water……WOW!!! Curious and starving for information I decided to research the effects of showering in unfiltered water.
I learned that showering in unfiltered tap water exposes you to far more contaminants than drinking tap water does, 7-10 times more! When you drink unfiltered tap water, your liver and kidneys filter out some of the contaminants. But when you shower in tap water, the contaminants are absorbed directly into the skin and inhaled into your lungs, a much more direct route to the blood stream. Virtually all synthetic chemicals are “volatile”, meaning they vaporize faster and at a lower temperature than water. These “VOCs” (Volatile Organic Chemicals) are released into the air, creating somewhat of an invisible gas chamber in your bathroom.
Most cities use chlorine or chloramines to disinfect the water supply, which when heated evaporate into the air becoming a VOC known as chloroform or THMs. Chloroform gas is a strong irritant to the lungs linked to asthma and respiratory problems. THMs are known carcinogens that have been linked to breast cancer, colon cancer and bladder cancer. Our primary exposure to both THMs and VOCs are from tap water.
Some of the effects of swimming in chlorine are mentioned in this recent article published by MSN:
