Health has a variety of definitions, which have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders.
Health care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care. The term includes work done in providing primary care, secondary care, tertiary care, and public health.
Barefoot doctors were healthcare providers who underwent basic medical training and worked in rural villages in China. They included farmers, folk healers, rural healthcare providers, and recent middle or secondary school graduates who received minimal basic medical and paramedical education. Their purpose was to bring healthcare to rural areas where urban-trained doctors would not settle. They promoted basic hygiene, preventive healthcare, and family planning and treated common illnesses. The name comes from southern farmers, who would often work barefoot in the rice paddies, and simultaneously worked as medical practitioners.
eHealth describes healthcare services which are supported by digital processes, communication or technology such as electronic prescribing, Telehealth, or Electronic Health Records (EHRs). The use of electronic processes in healthcare dated back to at least the 1990s. Usage of the term varies as it covers not just "Internet medicine" as it was conceived during that time, but also "virtually everything related to computers and medicine". A study in 2005 found 51 unique definitions. Some argue that it is interchangeable with health informatics with a broad definition covering electronic/digital processes in health while others use it in the narrower sense of healthcare practice using the Internet. It can also include health applications and links on mobile phones, referred to as mHealth or m-Health. Key components of eHealth include electronic health records (EHRs), telemedicine, health information exchange, mobile health applications, wearable devices, and online health information. These technologies enable healthcare providers, patients, and other stakeholders to access, manage, and exchange health information more effectively, leading to improved communication, decision-making, and overall healthcare outcomes.
Halfdan Theodor Mahler was a Danish physician. He served three terms as Director-General of the World Health Organization (WHO) from 1973 to 1988, and is widely known for his effort to combat tuberculosis and his role in having shaped the landmark Alma Ata Declaration that defined the Health for All by the Year 2000 strategy.
Population health has been defined as "the health outcomes of a group of individuals, including the distribution of such outcomes within the group". It is an approach to health that aims to improve the health of an entire human population. It has been described as consisting of three components. These are "health outcomes, patterns of health determinants, and policies and interventions".
The primary health center or primary healthcare center (PHC) is the basic structural and functional unit of the public health services in developing countries. PHCs were established to provide accessible, affordable and available primary health care to people, in accordance with the Alma Ata Declaration of 1978 by the member nations of the World Health Organization WHO.
Declaration of Alma-Ata was adopted at the International Conference on Primary Health Care (PHC), Almaty, Kazakh Soviet Socialist Republic, Soviet Union 6–12 September 1978. It expressed the need for urgent action by all governments, all health and development workers, and the world community to protect and promote the health of all people. It was the first international declaration underlining the importance of primary health care. The primary health care approach has since then been accepted by member countries of the World Health Organization (WHO) as the key to achieving the goal of "Health For All", but only in developing countries at first. This applied to all other countries five years later. The Alma-Ata Declaration of 1978 emerged as a major milestone of the twentieth century in the field of public health, and it identified primary health care as the key to the attainment of the goal of "Health For All" around the globe.
The social determinants of health (SDOH) are the economic and social conditions that influence individual and group differences in health status. They are the health promoting factors found in one's living and working conditions, rather than individual risk factors that influence the risk or vulnerability for a disease or injury. The distribution of social determinants is often shaped by public policies that reflect prevailing political ideologies of the area.
The healthcare delivery system of Pakistan is complex because it includes healthcare subsystems by federal governments and provincial governments competing with formal and informal private sector healthcare systems. Healthcare is delivered mainly through vertically managed disease-specific mechanisms. The different institutions that are responsible for this include: provincial and district health departments, parastatal organizations, social security institutions, non-governmental organizations (NGOs) and private sector. The country's health sector is also marked by urban-rural disparities in healthcare delivery and an imbalance in the health workforce, with insufficient health managers, nurses, paramedics and skilled birth attendants in the peripheral areas. Pakistan's gross national income per capita in 2021 was $4,990 and the total expenditure on health per capita in 2021 was Rs 657.2 Billion, constituting 1.4% of the country's GDP. The health care delivery system in Pakistan consists of public and private sectors. Under the constitution, health is primarily responsibility of the provincial government, except in the federally administered areas. Health care delivery has traditionally been jointly administered by the federal and provincial governments with districts mainly responsible for implementation. Service delivery is being organized through preventive, promotive, curative and rehabilitative services. The curative and rehabilitative services are being provided mainly at the secondary and tertiary care facilities. Preventive and promotive services, on the other hand, are mainly provided through various national programs; and community health workers’ interfacing with the communities through primary healthcare facilities and outreach activities. The state provides healthcare through a three-tiered healthcare delivery system and a range of public health interventions. Some government/ semi government organizations like the armed forces, Sui Gas, WAPDA, Railways, Fauji Foundation, Employees Social Security Institution and NUST provide health service to their employees and their dependants through their own system, however, these collectively cover about 10% of the population. The private health sector constitutes a diverse group of doctors, nurses, pharmacists, traditional healers, drug vendors, as well as laboratory technicians, shopkeepers and unqualified practitioners.
Global mental health is the international perspective on different aspects of mental health. It is 'the area of study, research and practice that places a priority on improving mental health and achieving equity in mental health for all people worldwide'. There is a growing body of criticism of the global mental health movement, and has been widely criticised as a neo-colonial or "missionary" project and as primarily a front for pharmaceutical companies seeking new clients for psychiatric drugs.
Deficient sanitation systems, poor nutrition, and inadequate health services have pushed Haiti to the bottom of the World Bank's rankings of health indicators. According to the United Nations World Food Programme, 80 percent of Haiti's population lives below the poverty line. In fact, 75% of the Haitian population lives off of $2.50 per day. Consequently, malnutrition is a significant problem. Half the population can be categorized as "food insecure," and half of all Haitian children are undersized as a result of malnutrition. Less than half the population has access to clean drinking water, a rate that compares poorly even with other less-developed nations. Haiti's healthy life expectancy at birth is 63 years. The World Health Organization (WHO) estimates that only 43 percent of the target population receives the recommended immunizations.
Services for mental health disorders provide treatment, support, or advocacy to people who have psychiatric illnesses. These may include medical, behavioral, social, and legal services.

Primary Health Centre (PHCs), sometimes referred to as public health centres, are state-owned rural and urban health care facilities in India. They are essentially single-physician clinics usually with facilities for minor surgeries. They are part of the government-funded public health system in India and are the most basic units of this system. As on 31 March 2019 there are 30,045 PHCs in India in which 24,855 are located on rural areas and 5,190 are on urban areas. The idea of creating PHCs in India was set forward by Bhore committee in 1946.
