Install a water filter. Fifty percent of our daily chlorine intake comes from bathing and showering. Not only is it absorbed through the skin, but as chlorine vaporizes in a hot environment we breathe it into our lungs, which can result in upper respiratory tract irritation. A quick, inexpensive and easy solution is to buy a shower filter or bath ball. Low cost at around $30 each, shower filters can be found at most hardware stores and are easily installed without any tools.
