WB meaning in Medical ?

Well-being, also known as wellness, prudential value or quality of life, refers to 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. 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. 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. Sometimes different types of well-being are distinguished, like mental well-being, physical well-being, economic wellbeing or emotional well-being. The different forms of well-being are often closely interlinked. For example, improved physical well-being (e.g., by reducing or ceasing an addiction) is associated with improved emotional well-being. As another example, better economic well-being (e.g., possessing more wealth) tends to be associated with better emotional well-being even in adverse situations such as the COVID-19 pandemic. Well-being plays a central role in ethics since what we ought to do depends, at least to some degree, on what would make someone's life go better or worse. According to welfarism, there are no other values besides well-being.

The terms well-being, pleasure and happiness are used in overlapping ways in everyday language but their meanings tend to come apart in technical contexts like philosophy or psychology. Pleasure refers to experience that feels good and is usually seen as one constituent of well-being. But there may be other factors, such as health, virtue, knowledge or the fulfillment of desires. Happiness, often seen either as "the individual’s balance of pleasant over unpleasant experience" or as the state of being satisfied with one's life as a whole, is also commonly taken to be a constituent of well-being.

Theories of well-being try to determine what is essential to all forms of well-being. Hedonistic theories equate well-being with the balance of pleasure over pain. Desire theories hold that well-being consists in desire-satisfaction: the higher the number of satisfied desires, the higher the well-being. Objective list theories state that a person's well-being depends on a list of factors that may include both subjective and objective elements.

Well-being is the central subject of positive psychology, whose goal is to discover the factors that contribute to human well-being. Martin Seligman, for example, suggests that these factors consist in having positive emotions, being engaged in an activity, having good relationships with other people, finding meaning in one's life and a sense of accomplishment in the pursuit of one's goals.

The Oxford English Dictionary traces the term well-being to a 16th-century calque of the Italian concept benessere.
