Still, other factors are beyond both individual and group choices, such as [[genetic disorder]]s. [12] => [13] => == History == [14] => The meaning of health has evolved over time. In keeping with the [[Biomedical model|biomedical]] perspective, early definitions of health focused on the theme of the body's ability to function; health was seen as a state of normal function that could be disrupted from time to time by [[disease]]. An example of such a definition of health is: "a state characterized by anatomic, physiologic, and psychological integrity; ability to perform personally valued family, work, and community roles; ability to deal with [[Human body|physical]], [[biological]], [[Psychology|psychological]], and [[social stress]]".{{Cite journal|last1=Stokes|first1=J.|last2=Noren|first2=J.|last3=Shindell|first3=S.|date=1 January 1982|title=Definition of terms and concepts applicable to clinical preventive medicine|journal=Journal of Community Health|volume=8|issue=1|pages=33–41|issn=0094-5145|pmid=6764783|doi=10.1007/bf01324395|s2cid=1748896}} Then, in 1948, in a radical departure from previous definitions, the [[World Health Organization]] (WHO) proposed a definition that aimed higher, linking health to [[well-being]], in terms of "physical, mental, and social well-being, and not merely the absence of disease and infirmity".{{Cite book|url=https://www.who.int/iris/handle/10665/37089|title=The first ten years of the World Health Organization|last=World Health Organization|publisher=WHO|year=1958|location=Geneva|isbn=9789241560146|publication-date=1958}} Although this definition was welcomed by some as being innovative, it was also criticized for being vague and excessively broad and was not construed as measurable. For a long time, it was set aside as an impractical ideal, with most discussions of health returning to the practicality of the biomedical model.{{Cite web|url=http://phprimer.afmc.ca/Part1-TheoryThinkingAboutHealth/ConceptsOfHealthAndIllness/DefinitionsofHealth|title=Part 1 – Theory: Thinking About Health Chapter 1 Concepts of Health and Illness|website=phprimer.afmc.ca|access-date=22 June 2016|archive-url=https://web.archive.org/web/20160812145405/http://phprimer.afmc.ca/Part1-TheoryThinkingAboutHealth/ConceptsOfHealthAndIllness/DefinitionsofHealth|archive-date=12 August 2016|url-status=dead}} [15] => [16] => Just as there was a shift from viewing disease as a state to thinking of it as a process, the same shift happened in definitions of health. Again, the WHO played a leading role when it fostered the development of the health promotion movement in the 1980s. This brought in a new conception of health, not as a state, but in dynamic terms of resiliency, in other words, as "a resource for living". In 1984, WHO revised the definition of health defined it as "the extent to which an individual or group is able to realize aspirations and satisfy needs and to change or cope with the environment. Health is a resource for everyday life, not the objective of living; it is a positive concept, emphasizing social and personal resources, as well as physical capacities."{{Cite book|url=https://www.who.int/iris/handle/10665/107835|title=Health promotion : a discussion document on the concept and principles : summary report of the Working Group on Concept and Principles of Health Promotion, Copenhagen, 9–13 July 1984|last=World Health Organization.

Mental, intellectual, emotional and social health referred to a person's ability to handle stress, to acquire skills, to maintain relationships, all of which form resources for resiliency and [[independent living]].

[[Relaxation technique]]s are physical methods used to relieve stress. Psychological methods include [[cognitive therapy]], [[meditation]], and [[Optimism|positive thinking]], which work by reducing response to stress. Improving relevant skills, such as [[problem solving]] and [[time management]] skills, reduces uncertainty and builds confidence, which also reduces the reaction to stress-causing situations where those skills are applicable.
