If someone asks what the dirtiest part of the body is, most will answer “the anus.” However, the anus is not even among the five dirtiest parts of the body. According to researchers at Harvard University, more than 615 types of bacteria live in the mouth, making the mouth the dirtiest part of the body. Here is a list of the 9 dirtiest body parts you never thought were dirty:

There are many bacteria living in our mouths that can harm your health. That’s why it’s important to clean it often and well.

Underarms harbor dangerous bacteria that make our sweat smell bad. Deodorants and perfumes can mask the smell but won’t kill the bacteria, so wash the affected area with a very strong antimicrobial soap.

The wax in the ears lubricates and protects the ear canal from bacteria, insects and water, making the ears one of the dirtiest parts of the body. Not cleaning them can lead to fungal infections, even though the ears’ self-cleaning mechanism keeps the outer layer of the ears clean.

Both the mouth and the tongue contain many harmful bacteria, and the tongue can even change color due to the presence of bacteria. When you brush your mouth, it is best to also brush your tongue to prevent oral problems.

The skin under the nails is very dirty, and the bacteria under them can even be fatal in some cases! Wash your hands and nails thoroughly before preparing or eating food, as this can be a matter of life or death.

If your scalp is itchy, but not because of dandruff, you may be dealing with some kind of bacterial infection. Wash your hair regularly to avoid bacterial damage to the scalp.

The surface may be clean, but the navel often contains dangerous bacteria. Many people do not pay attention to their navel, but if it is not washed properly during the shower, it can lead to infections and even swelling, so be sure to clean it thoroughly.

The anus contains a lot of harmful bacteria that can be deadly if you don’t clean it well.

nasal cavity
You may not notice dirt in your nose, but every day we breathe in hundreds of dangerous bacteria through our noses. Clean it well, but not with your fingers – use the nasal irrigation system instead.
