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. 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. This suggests that the positive health benefits of natural space in urban neighborhoods should be taken into account in public policy and land use.
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.
Nearly one in three patients receiving NHS hospital treatment is privately insured and could have the cost paid for by their insurer. Some private schemes provide cash payments to patients who opt for NHS treatment, to deter use of private facilities. A report, by private health analysts Laing and Buisson, in November 2012, estimated that more than 250,000 operations were performed on patients with private medical insurance each year at a cost of £359 million. In addition, £609 million was spent on emergency medical or surgical treatment. Private medical insurance does not normally cover emergency treatment but subsequent recovery could be paid for if the patient were moved into a private patient unit.
Since the late 1970s, the federal Healthy People Initiative has been a visible component of the United States’ approach to improving population health. In each decade, a new version of Healthy People is issued, featuring updated goals and identifying topic areas and quantifiable objectives for health improvement during the succeeding ten years, with assessment at that point of progress or lack thereof. Progress has been limited to many objectives, leading to concerns about the effectiveness of Healthy People in shaping outcomes in the context of a decentralized and uncoordinated US health system. Healthy People 2020 gives more prominence to health promotion and preventive approaches and adds a substantive focus on the importance of addressing social determinants of health. A new expanded digital interface facilitates use and dissemination rather than bulky printed books as produced in the past. The impact of these changes to Healthy People will be determined in the coming years.
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.
