A dentist would tell you to brush your teeth twice a day; a dermatologist would advice you to shower with this soap and not the other; and a gynaecologist (a certified one) would recommend a routine (to the women) that would make 'Miss V' happy always.
In short, every health expert will tell you how to keep their area of expertise clean as some of the infections we get are due to poor personal hygiene failing to clean the right places right.
So, what are the dirtiest parts of the human body?
Most people think that their mouths are dirty only when they start having bad breath. That is true to some extent but your mouth can be dirty without having a bad breath as there are more than seven causes of halitosis.
The mouth makes it to the list of the dirtiest parts of the human body thanks to a research by scientists at Harvard School of Dental Medicine who discovered more than 615 different types of bacteria that can live in the mouth in their millions.

Another study by Dutch researchers, published in the Microbiome journal, found that that kissing your partner for 10 seconds could lead to transferring over 80 million germs. Anyway, do not freak out as the scientists say most of the bacteria in the human mouth are not harmful.
To many, the rectal area would easily be crowned the dirtiest due to its relationship with fecal matter which contains lots of bacteria. However, if wiped well, the area easily becomes one of the cleanest parts of the body.
A study by National Human Genome Research Institute found that the highest concentration of bacteria (after bathing) was on the forearm (between the elbow and wrist).
The scientists said that over 44 types of bacteria inhabit the forearm and could stay there for long as people rarely wash this part of the body thoroughly.
4. Under the finger nails
People touch a lot of things during the day and most of the dirt get collected under the fingernails and that is why it is often recommended to keep them short.
5. Belly button
If not cleaned well, the navel would easily pass as the dirtiest part of the body as some people rarely wash it with the same care they use for other parts of the body.
The belly button can accumulate dead skin, hair, sweat and body lotion that accumulate over time to form a brownish mud.
Your face is always exposed to all manner of dirt hence getting it to this list. Ears, eyes and the nose all accumulate dirt.
To the uncircumcised males, the foreskin can collect dirt a chunk of dirt, know as smegma, which has not so pleasant smell.
In contrast, the female vagina is a self-cleaning organ with bacteria that eat dead skin and also produces a substance that kills unwanted bacteria (that explains the fading often seen in that area on underwear). But is important to note that even the organ must be cleaned.
On a lighter note, sociologists will tell you the dirtiest part of the body is the mind though there is no scientific research to prove their claims.
All in all, health experts unanimously agree that all parts of the body can get filthy if not well taken care of.
