Health and hygiene

Health is the level of functional and metabolic  efficiency of a living organism. In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental, psychological and social changes with environment.The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies, and because of the problem created by use of the word "complete". Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.Classification systems such as the WHO Family of International Classifications, including the International Classification of Functioning, Disability and Health (ICF) and the International Classification of Diseases (ICD), are commonly used to define and measure the components of health.
Important to establish to types of health; physical and mental health. Mental health refers to a persons psychological well-being and how they feel. Physical health has many different components such as physical activity, nutrition and diet and sleep/rest. Physical health can have a major impact on mental health and vice versa.
Hygiene is a set of practices performed to preserve health. According to the World Health Organization (WHO), "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases."
Many people equate hygiene with 'cleanliness,' but hygiene is a broad term. It includes such personal habit choices as how frequently to bathe, wash hands, trim fingernails, and change clothing. It also includes attention to keeping surfaces in the home and workplace, including bathroom facilities, clean and pathogen-free.
Some regular hygiene practices may be considered good habits by a society, while the neglect of hygiene can be considered disgusting, disrespectful, or threatening.
