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 has been described as "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals." It is concerned with threats to the overall health of a community based on population health analysis. The population in question can be as small as a handful of people or as large as all the inhabitants of several continents (for instance, in the case of a pandemic). Public health has many sub-fields, but typically includes the interdisciplinary categories of epidemiology, biostatistics and health services. Environmental health, community health, behavioral health, and occupational health are also important areas of public health.
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". 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". Thus, health referred to the ability to maintain homeostasis and recover from insults. 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. This opens up many possibilities for health to be taught, strengthened and learned.
In a study in JAMA Internal Medicine, researchers reported that people who ate the most sugar had a higher risk of death from heart disease, even if they weren’t overweight. Another study found that spending just three months on a sugar-heavy diet changed fat metabolism in healthy men, causing them to develop non-alcoholic fatty-liver disease, which boosts the risk of cardiovascular disease.
Comprehensive health insurance pays a percentage of the cost of hospital and physician charges after a deductible (usually applies to hospital charges) or a co-pay (usually applies to physician charges, but may apply to some hospital services) is met by the insured. These plans are generally expensive because of the high potential benefit payout — $1,000,000 to $5,000,000 is common — and because of the vast array of covered benefits.

Organized interventions to improve health based on the principles and procedures developed through the health sciences are provided by practitioners trained in medicine, nursing, nutrition, pharmacy, social work, psychology, occupational therapy, physical therapy and other health care professions. Clinical practitioners focus mainly on the health of individuals, while public health practitioners consider the overall health of communities and populations. Workplace wellness programs are increasingly adopted by companies for their value in improving the health and well-being of their employees, as are school health services in order to improve the health and well-being of children.
Out-of-pocket maxima: Similar to coverage limits, except that in this case, the insured person's payment obligation ends when they reach the out-of-pocket maximum, and health insurance pays all further covered costs. Out-of-pocket maxima can be limited to a specific benefit category (such as prescription drugs) or can apply to all coverage provided during a specific benefit year.
Health psychology, developed in the late 1970s, is its own domain of inquiry. Also called a medical psychologist, the health psychologist helps individuals explore the link between emotions and physical health. The health psychologist also helps physicians and medical professionals understand the emotional effects of a patient’s illness or disease. They practice in the areas of chronic pain management, oncology, physical rehabilitation, addiction treatment, eating disorders, and others. This professional can be found in clinics, hospitals, private practice, and public health agencies. Some also work in corporate settings to promote health and wellness among employees, engaging in workplace policies and decision-making.
The maintenance and promotion of health is achieved through different combination of physical, mental, and social well-being, together sometimes referred to as the "health triangle." The WHO's 1986 Ottawa Charter for Health Promotion further stated that health is not just a state, but also "a resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities."
In 2013 a state funded private care insurance was introduced ("Private Pflegeversicherung"). Insurance contracts that fit certain criteria are subsidised with 60 Euro per year. It is expected that the number of contracts will grow from 400,000 by end of 2013 to over a million within the next few years. These contracts have been criticized by consumer rights foundations.

Social Science & Medicine. 54 (10): 1559–87. doi:10.1016/S0277-9536(01)00137-X. PMID 12061488. Retrieved 10 March 2013. As Germany has the world's oldest SHI [social health insurance] system, it naturally lends itself to historical analyses.

No individual applying for health coverage through the individual marketplace will be discouraged from applying for benefits, turned down for coverage or charged more premium because of health status, medical condition, mental illness claims experience, medical history, genetic information or health disability. In addition, no individual will be denied coverage based on race, color, religion, national origin, sex, sexual orientation, marital status, personal appearance, political affiliation or source of income.
Health, as defined by the World Health Organization (WHO), is "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, as it may have limited value for implementation. Health may be defined as the ability to adapt and manage physical, mental and social challenges throughout life.
