Well-being, or wellbeing,[1] also known as wellness, prudential value, prosperity or quality of life, is what is intrinsically valuable relative to someone. So the well-being of a person is what is ultimately good for this person, what is in the self-interest of this person.[2] Well-being can refer to both positive and negative well-being. In its positive sense, it is sometimes contrasted with ill-being as its opposite.[3] The term "subjective well-being" denotes how people experience and evaluate their lives, usually measured in relation to self-reported well-being obtained through questionnaires.[4]
Well-being has been traditionally treated as a variable ranging from none to a high degree of well-being. This usage of well-being has in later times been widened to also include a negative aspect. With the aim of understanding how different route environmental variables affect the wellbeing during walking or cycling, the term "environmental unwellbeing" has been coined.[5][6]
