Public Health and the Definition of Health

According to the World Health Organization, health is a state of complete physical and mental well-being, free from disease and infirmity. While this definition is generally accurate, it doesn’t capture the holistic nature of life. For example, people with diabetes receive medication to control their condition, while those with back pain undergo physiotherapy to control their pain. Neither of these situations are considered to be examples of complete physical wellbeing. However, if the person is physically healthy, he or she is considered healthy.


A good definition of health depends on the perspective of the person. At its most simplistic, health is the absence of disease. If the goal of health promotion is to prevent disease, the focus would be on eliminating or minimizing the number of those suffering from these conditions. However, the definition of “health” goes beyond the physical state. A person’s mental capacity to function is an important part of being healthy. Performing activities and exercising regularly can improve the capacity to cope with life’s challenges.

A public health approach focuses on the physical and mental aspects of health. It emphasizes the physical and social capacities of a person and their ability to live a healthy life. It also focuses on preventing disease and promoting prevention and treatment. It aims to achieve this by encouraging people to maintain their social and physical well-being and to engage in a healthy lifestyle. Lastly, it educates people on the importance of preventing and treating diseases.

The definition of health is also important. While the medical model focused on the absence of disease, the biopsychosocial approach focuses on the physiological, psychological, and social components of disease. In addition to prevention, public health promotes healthy lifestyles and the maintenance of relationships among individuals. For example, promoting healthy living habits, including exercise, reduces stress, and supports a balanced social life. A public health program is essential for achieving this goal.

A public health plan can include a wide range of resources, such as food, water, and energy. Its goal is to ensure that people maintain their well-being by avoiding harmful situations and activities. Its goals should be to prevent disease and to protect a society from ill health. It should also promote a culture of health and prevent the occurrence of disease. For example, a public health plan could encourage a person to drink water instead of bottled water, or encourage them to drink more water.

The World Health Organization’s constitution defines health as the state of complete physical and mental well-being. The word “health” refers to not only the absence of disease but also the presence of healthy people. By definition, health includes a person’s mental and social well-being. Furthermore, it can include a country’s health and social development. For example, a healthy community is a healthy one where the population can grow and thrive.
