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.
Since 1974, New Zealand has had a system of universal no-fault health insurance for personal injuries through the Accident Compensation Corporation (ACC). The ACC scheme covers most of the costs of related to treatment of injuries acquired in New Zealand (including overseas visitors) regardless of how the injury occurred, and also covers lost income (at 80 percent of the employee's pre-injury income) and costs related to long-term rehabilitation, such as home and vehicle modifications for those seriously injured. Funding from the scheme comes from a combination of levies on employers' payroll (for work injuries), levies on an employee's taxable income (for non-work injuries to salary earners), levies on vehicle licensing fees and petrol (for motor vehicle accidents), and funds from the general taxation pool (for non-work injuries to children, senior citizens, unemployed people, overseas visitors, etc.)
Generally, the context in which an individual lives is of great importance for both his health status and quality of their life. It is increasingly recognized that health is maintained and improved not only through the advancement and application of health science, but also through the efforts and intelligent lifestyle choices of the individual and society. According to the World Health Organization, the main determinants of health include the social and economic environment, the physical environment and the person's individual characteristics and behaviors.

Initially the health insurance law of 1883 covered blue-collar workers in selected industries, craftspeople and other selected professionals.6 It is estimated that this law brought health insurance coverage up from 5 to 10 per cent of the total population.
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.
Private Health Insurance Rebate: The government subsidises the premiums for all private health insurance cover, including hospital and ancillary (extras), by 10%, 20% or 30%, depending on age. The Rudd Government announced in May 2009 that as of July 2010, the Rebate would become means-tested, and offered on a sliding scale. While this move (which would have required legislation) was defeated in the Senate at the time, in early 2011 the Gillard Government announced plans to reintroduce the legislation after the Opposition loses the balance of power in the Senate. The ALP and Greens have long been against the rebate, referring to it as "middle-class welfare".
The national system of health insurance was instituted in 1945, just after the end of the Second World War. It was a compromise between Gaullist and Communist representatives in the French parliament. The Conservative Gaullists were opposed to a state-run healthcare system, while the Communists were supportive of a complete nationalisation of health care along a British Beveridge model.
