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.[15]
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.
An important way to maintain your personal health is to have a healthy diet. A healthy diet includes a variety of plant-based and animal-based foods that provide nutrients to your body. Such nutrients give you energy and keep your body running. Nutrients help build and strengthen bones, muscles, and tendons and also regulate body processes (i.e. blood pressure). The food guide pyramid is a pyramid-shaped guide of healthy foods divided into sections. Each section shows the recommended intake for each food group (i.e. Protein, Fat, Carbohydrates, and Sugars). Making healthy food choices is important because it can lower your risk of heart disease, developing some types of cancer, and it will contribute to maintaining a healthy weight.[43]
Usage Note: Some people insist on maintaining a distinction between the words healthy and healthful. In this view, healthful means "conducive to good health" and is applied to things that promote health, while healthy means "possessing good health," and is applied solely to people and other organisms. Accordingly, healthy people have healthful habits. However, healthy has been used to mean "healthful" since the 1500s, as in this example from John Locke's Some Thoughts Concerning Education: "Gardening ... and working in wood, are fit and healthy recreations for a man of study or business." In fact, the word healthy is far more common than healthful when modifying words like diet, exercise, and foods, and healthy may strike many readers as more natural in many contexts. Certainly, both healthy and healthful must be considered standard in describing that which promotes health.
What is added sugar, anyway? It refers to sugar that is not found naturally in food. Honey in your tea is added sugar. The sugar in a banana is not. Some foods like yogurts and fruit bars may have both natural and added sugars, and it’s usually unclear from labels what the ratios of each are. But the FDA’s new food labels—which must be adopted by Jan. 1, 2020—will require companies to spell out the amount of “added sugar,” making it much easier to track your sugar load.

Hospital and medical expense policies were introduced during the first half of the 20th century. During the 1920s, individual hospitals began offering services to individuals on a pre-paid basis, eventually leading to the development of Blue Cross organizations.[63] The predecessors of today's Health Maintenance Organizations (HMOs) originated beginning in 1929, through the 1930s and on during World War II.[65][66]

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.

Insurance companies are not allowed to have co-payments, caps, or deductibles, or to deny coverage to any person applying for a policy, or to charge anything other than their nationally set and published standard premiums. Therefore, every person buying insurance will pay the same price as everyone else buying the same policy, and every person will get at least the minimum level of coverage.


Sleep is an essential component to maintaining health. In children, sleep is also vital for growth and development. Ongoing sleep deprivation has been linked to an increased risk for some chronic health problems. In addition, sleep deprivation has been shown to correlate with both increased susceptibility to illness and slower recovery times from illness.[46] In one study, people with chronic insufficient sleep, set as six hours of sleep a night or less, were found to be four times more likely to catch a cold compared to those who reported sleeping for seven hours or more a night.[47] Due to the role of sleep in regulating metabolism, insufficient sleep may also play a role in weight gain or, conversely, in impeding weight loss.[48] Additionally, in 2007, the International Agency for Research on Cancer, which is the cancer research agency for the World Health Organization, declared that "shiftwork that involves circadian disruption is probably carcinogenic to humans," speaking to the dangers of long-term nighttime work due to its intrusion on sleep.[49] In 2015, the National Sleep Foundation released updated recommendations for sleep duration requirements based on age and concluded that "Individuals who habitually sleep outside the normal range may be exhibiting signs or symptoms of serious health problems or, if done volitionally, may be compromising their health and well-being."[50]
These adjectives refer to a state of good physical health. Healthy stresses the absence of disease or infirmity and is used of whole organisms as well as their parts: a healthy baby; flossed daily to promote healthy gums. Wholesome suggests a state of good health associated with youthful vitality or clean living: "In truth, a wholesome, ruddy, blooming creature she was" (Harriet Beecher Stowe).
Health insurance is insurance that covers the whole or a part of the risk of a person incurring medical expenses, spreading the risk over a large number of persons. By estimating the overall risk of health care and health system expenses over the risk pool, an insurer can develop a routine finance structure, such as a monthly premium or payroll tax, to provide the money to pay for the health care benefits specified in the insurance agreement.[1] The benefit is administered by a central organization such as a government agency, private business, or not-for-profit entity.
In addition to safety risks, many jobs also present risks of disease, illness and other long-term health problems. Among the most common occupational diseases are various forms of pneumoconiosis, including silicosis and coal worker's pneumoconiosis (black lung disease). Asthma is another respiratory illness that many workers are vulnerable to. Workers may also be vulnerable to skin diseases, including eczema, dermatitis, urticaria, sunburn, and skin cancer.[60][61] Other occupational diseases of concern include carpal tunnel syndrome and lead poisoning.
Co payments were introduced in the 1980s in an attempt to prevent over utilization. The average length of hospital stay in Germany has decreased in recent years from 14 days to 9 days, still considerably longer than average stays in the United States (5 to 6 days).[25][26] Part of the difference is that the chief consideration for hospital reimbursement is the number of hospital days as opposed to procedures or diagnosis. Drug costs have increased substantially, rising nearly 60% from 1991 through 2005. Despite attempts to contain costs, overall health care expenditures rose to 10.7% of GDP in 2005, comparable to other western European nations, but substantially less than that spent in the U.S. (nearly 16% of GDP).[27]

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".[14]

Lifetime Health Cover: If a person has not taken out private hospital cover by 1 July after their 31st birthday, then when (and if) they do so after this time, their premiums must include a loading of 2% per annum for each year they were without hospital cover. Thus, a person taking out private cover for the first time at age 40 will pay a 20 percent loading. The loading is removed after 10 years of continuous hospital cover. The loading applies only to premiums for hospital cover, not to ancillary (extras) cover.

A contract between an insurance provider (e.g. an insurance company or a government) and an individual or his/her sponsor (e.g. an employer or a community organization). The contract can be renewable (e.g. annually, monthly) or lifelong in the case of private insurance, or be mandatory for all citizens in the case of national plans. The type and amount of health care costs that will be covered by the health insurance provider are specified in writing, in a member contract or "Evidence of Coverage" booklet for private insurance, or in a national health policy for public insurance.


Insurance companies are not allowed to have co-payments, caps, or deductibles, or to deny coverage to any person applying for a policy, or to charge anything other than their nationally set and published standard premiums.

The environment is often cited as an important factor influencing the health status of individuals. This includes characteristics of the natural environment, the built environment and the social environment. Factors such as clean water and air, adequate housing, and safe communities and roads all have been found to contribute to good health, especially to the health of infants and children.[19][30] Some studies have shown that a lack of neighborhood recreational spaces including natural environment leads to lower levels of personal satisfaction and higher levels of obesity, linked to lower overall health and well being.[31] This suggests that the positive health benefits of natural space in urban neighborhoods should be taken into account in public policy and land use.
