In a recent study conducted by researchers at the University of Colorado at Boulder, shower heads were found to contain bacteria potentially dangerous to those that had weakened immune systems. Moreover, the researchers found that not only will cleaning with bleach not kill the bacteria, but in one case the levels were found to be three times higher post cleaning.
- Install an all-metal shower head (not metal-coated plastic), as many studies have shown that bacteria attach and grow better on plastic than metal
- Change out your shower head every six months
- Install a filtering shower head. There are several designed those that have immune issues such as this shower head, which was found effective in another study.
- Take baths, which will create fewer aerosols.
