Definition for Hygiene
From Biology Forums Dictionary
Hygiene is a set of practices performed for the preservation of health. While in modern medical sciences there is a set of standards of hygiene recommended for different situations, what is considered hygienic or not can vary between different cultures, genders and etarian groups. Some regular hygienic practices may be considered good habits by a society while the neglect of hygiene can be considered disgusting, disrespectful or even threatening.
Sanitation involves the hygenic disposal and treatment by the civic authority of potentially unhealthy human waste, such as sewerage and drainage.
