Head
If your head itches, but it’s not because of dandruff, you might be dealing with some type of bacterial infection. Wash your hair regularly to avoid bacteria from damaging your scalp.
Belly button
It may be clean on the surface, but the belly button is often home to dangerous bacteria. Many people don’t pay attention to their navel, but not cleaning it well during a shower can result in infections and even tumors, so make sure you clean it thoroughly.
Bottoms
The anus contains many harmful bacteria which could turn out to be deadly if you don’t clean it well.
Nasal cavity
You might not notice dirt in your nose, but we inhale hundreds of dangerous bacteria through our nose every day. Clean it well, but not by picking it with your fingers – use a nasal irrigation system instead.
