Personal hygiene is something some people do not take serious but it is an issue that can have negative impact on you. Body or mouth odour do not just start in a day, it is something that develops over a period of time because of the personal hygiene that you practice.
The reason why you need to practice personal hygiene is because it can solve issues you have that were caused by bad personal hygiene practices and it can also help prevent having such issues. So if you are having body odour or mouth odour, what you need to do is practice basic personal hygiene and it will be gone.
These are some of the basic personal hygiene you can practice so as to maintain your body and keep yourself clean.
