What are the advantages and disadvantages of cleanliness?

There are several advantages and disadvantages of
cleanliness, although I think most people would agree that there are more positive things that
come from being clean than there are negative.

Positives of cleanliness

• Kills germs- Some germs can make you very
  ill, especially if they have been around for a while. So it is very
  important that you keep yourself and your house clean as a health
  benefit. It can also prevent allergies, by removing dust from
  surfaces.

• Mental health- Cleaning something can leave
  you with a sense of satisfaction that has actually been proven to
  boost mental health. If your house is dirty, people inside it will feel anxious
  and  stressed, including you!

• Social factor- If you are unwashed then this
  can be off-putting to people. It is socially expected for people to
  be clean when out in public. You may struggle to make friends if you don't take care of your personal hygiene.

Negatives of cleanliness

• Affects immune system- Studies have shown
  that if you are over clean then this can negatively affect your
  immune system. Over cleaning will not allow your immune system to build up
  strength against bacteria, so it won't be used to any unknown germs it comes into
  contact with.

• Allergies - Some soaps and cleaning products contain chemicals that can cause irritation to the skin, or trigger allergies in certain people.
