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.
The focus of public health interventions is to prevent and manage diseases, injuries and other health conditions through surveillance of cases and the promotion of healthy behavior, communities, and (in aspects relevant to human health) environments. Its aim is to prevent health problems from happening or re-occurring by implementing educational programs, developing policies, administering services and conducting research. In many cases, treating a disease or controlling a pathogen can be vital to preventing it in others, such as during an outbreak. Vaccination programs and distribution of condoms to prevent the spread of communicable diseases are examples of common preventive public health measures, as are educational campaigns to promote vaccination and the use of condoms (including overcoming resistance to such).
Natural health care products are currently regulated under the Natural Health Product Regulations, under the authority of the Food and Drugs Act. The regulations address the sale of natural health products, manufacture, packaging, labelling and importation for sale of natural health products, the distribution of natural health products, and the storage of natural health products. Under the regulations, all natural health products require a Natural Product Number (NPN), analogous to the Drug Identification Numbers (DINs) used to identify and monitor drugs in Canada.
A recent survey found that even though many older adults enjoy an active sex life, few talk about their sexual health with their doctor or other health care provider. It’s important to have an open line of communication because in general, sexuality changes over time, and many older men encounter problems that can interfere with performance, such as erectile dysfunction or problems with arousal, energy, and stamina.

Many governments view occupational health as a social challenge and have formed public organizations to ensure the health and safety of workers. Examples of these include the British Health and Safety Executive and in the United States, the National Institute for Occupational Safety and Health, which conducts research on occupational health and safety, and the Occupational Safety and Health Administration, which handles regulation and policy relating to worker safety and health.
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.
