Health science is the branch of science focused on health. There are two main approaches to health science: the study and research of the body and health-related issues to understand how humans (and animals) function, and the application of that knowledge to improve health and to prevent and cure diseases and other physical and mental impairments. The science builds on many sub-fields, including biology, biochemistry, physics, epidemiology, pharmacology, medical sociology. Applied health sciences endeavor to better understand and improve human health through applications in areas such as health education, biomedical engineering, biotechnology and public health.

Public health also takes various actions to limit the health disparities between different areas of the country and, in some cases, the continent or world. One issue is the access of individuals and communities to health care in terms of financial, geographical or socio-cultural constraints to accessing and using services. Applications of the public health system include the areas of maternal and child health, health services administration, emergency response, and prevention and control of infectious and chronic diseases.
The definition of health has evolved over time. In keeping with the 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 physical, biological, psychological, and social stress”. 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”. Although this definition was welcomed by some as being innovative, it was also criticized as being vague, excessively broad and was not construed as measurable. For a long time, it was set aside as an impractical ideal and most discussions of health returned to the practicality of the biomedical model.

Genetics, or inherited traits from parents, also play a role in determining the health status of individuals and populations. This can encompass both the predisposition to certain diseases and health conditions, as well as the habits and behaviors individuals develop through the lifestyle of their families. For example, genetics may play a role in the manner in which people cope with stress, either mental, emotional or physical. For example, obesity is a significant problem in the United States that contributes to bad mental health and causes stress in the lives of great numbers of people. (One difficulty is the issue raised by the debate over the relative strengths of genetics and other factors; interactions between genetics and environment may be of particular importance.)
Systematic activities to prevent or cure health problems and promote good health in humans are undertaken by health care providers. Applications with regard to animal health are covered by the veterinary sciences. The term “healthy” is also widely used in the context of many types of non-living organizations and their impacts for the benefit of humans, such as in the sense of healthy communities, healthy cities or healthy environments. In addition to health care interventions and a person’s surroundings, a number of other factors are known to influence the health status of individuals, including their background, lifestyle, and economic, social conditions and spirituality; these are referred to as “determinants of health.” Studies have shown that high levels of stress can affect human health.
Roughly a quarter of all adults 18 and over in the US are considered diagnosable with mental illness. Mental illnesses are the leading cause of disability in the US and Canada. Examples include, schizophrenia, ADHD, major depressive disorder, bipolar disorder, anxiety disorder, post-traumatic stress disorder and autism.
The great positive impact of public health programs is widely acknowledged. Due in part to the policies and actions developed through public health, the 20th century registered a decrease in the mortality rates for infants and children and a continual increase in life expectancy in most parts of the world. For example, it is estimated that life expectancy has increased for Americans by thirty years since 1900, and worldwide by six years since 1990.
Mental illness is described as ‘the spectrum of cognitive, emotional, and behavioral conditions that interfere with social and emotional well-being and the lives and productivity of people. Having a mental illness can seriously impair, temporarily or permanently, the mental functioning of a person. Other terms include: ‘mental health problem’, ‘illness’, ‘disorder’, ‘dysfunction’.

A number of types of health issues are common around the globe. Disease is one of the most common. According to GlobalIssues.org, approximately 36 million people die each year from non-communicable (not contagious) disease including cardiovascular disease, cancer, diabetes and chronic lung disease (Shah, 2014).
Focusing more on lifestyle issues and their relationships with functional health, data from the Alameda County Study suggested that people can improve their health via exercise, enough sleep, maintaining a healthy body weight, limiting alcohol use, and avoiding smoking. Health and illness can co-exist, as even people with multiple chronic diseases or terminal illnesses can consider themselves healthy.
Social wellness helps you perform social roles effectively and comfortably, and create a support network. This dimension of wellness allows you to not only develop encouraging relationships with peers, but also intimate relationships with romantic partners.
The concept of the “health field,” as distinct from medical care, emerged from the Lalonde report from Canada. The report identified three interdependent fields as key determinants of an individual’s health. These are:

The term was partly inspired by the preamble to the World Health Organization’s 1948 constitution which said: “Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” It was initially brought to use in the US by Halbert L. Dunn, M.D. in the 1950s; Dunn was the chief of the National Office of Vital Statistics and discussed “high-level wellness,” which he defined as “an integrated method of functioning, which is oriented toward maximizing the potential of which the individual is capable.” The term “wellness” was then adopted by John Travis who opened a “Wellness Resource Center” in Mill Valley, California in the mid-1970s, which was seen by mainstream culture as part of the hedonistic culture of Northern California at that time and typical of the Me generation. Travis marketed the center as alternative medicine, opposed to what he said was the disease-oriented approach of medicine. The concept was further popularized by Robert Rodale through Prevention magazine, Bill Hetler, a doctor at University of Wisconsin–Stevens Point, who set up an annual academic conference on wellness, and Tom Dickey, who established the Berkeley Wellness Letter in the 1980s. The term had become accepted as standard usage in the 1990s.
Bodily injuries are also a common health issue worldwide. These injuries, including broken bones, fractures, and burns can reduce a person’s quality of life or can cause fatalities including infections that resulted from the injury or the severity injury in general (Moffett, 2013).

In the first decade of the 21th century, the conceptualization of health as an ability opened the door for self-assessments to become the main indicators to judge the performance of efforts aimed at improving human health. It also created the opportunity for every person to feel healthy, even in the presence of multiple chronic diseases, or a terminal condition, and for the re-examination of determinants of health, away from the traditional approach that focuses on the reduction of the prevalence of diseases.

By the late 2000s the concept had become widely used in employee assistance programs in workplaces, and funding for development of such programs in small business was included in the Affordable Care Act.
Spiritual wellness allows you to develop a set of values that help you seek meaning and purpose. Spirituality can be represented in many ways, for example, through relaxation or religion. But being spiritually well means knowing which resources to use to cope with issues that come up in everyday life.

Health is the ability of a biological system to acquire, convert, allocate, distribute, and utilize energy with maximum efficiency. The World Health Organization (WHO) defined human health in a 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”, which makes it practically impossible to achieve. Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction. 
Many teens suffer from mental health issues in response to the pressures of society and social problems they encounter. Some of the key mental health issues seen in teens are: depression, eating disorders, and drug abuse. There are many ways to prevent these health issues from occurring such as communicating well with a teen suffering from mental health issues. Mental health can be treated and be attentive to teens’ behavior.

The notions behind the term share the same roots as the alternative medicine movement, in 19th-century movements in the US and Europe that sought to optimize health and to consider the whole person, like New Thought, Christian Science, and Lebensreform.
Lifestyle choices are contributing factors to poor health in many cases. These include smoking cigarettes, and can also include a poor diet, whether it is overeating or an overly constrictive diet. Inactivity can also contribute to health issues and also a lack of sleep, excessive alcohol consumption, and neglect of oral hygiene (Moffett2013).There are also genetic disorders that are inherited by the person and can vary in how much they affect the person and when they surface (Moffett, 2013).
