Dental
Dental hygiene involves more than just having white teeth. A good dental hygiene routine can help prevent issues such as gum disease and cavities. It can also prevent bad breath.
Body
Several million sweat glands cover the human body. When bacteria break down sweat, the process creates a smell or body odor.
Washing the body will help prevent skin irritation, as well as removing the bacteria that cause body odor. Washing the hair removes oil and keeps a person looking clean and fresh.
