Now, I’m not a rocket scientist but it does not take one to figure out that the shower was the common denominator in my coughing. After looking at the shower head I noticed black and green slime inside some of the showerhead holes and then after spraying it with a household bleach I noticed the slime (mold) disappeared. Now showerheads are not expensive and can be replaced for under $20 for a simple showerhead. So, after a trip to the local hardware store I had a new and mold free showerhead installed in my shower.
So, if your showerhead has any signs of abnormal growth or deposits on it, go ahead and do yourself and family a favor and replace it. They are simple to replace, and the rewards can be great.
