Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. This definition was first adopted by the World Health Organization (WHO) in 1948 and has been reaffirmed several times since then. It reflects the WHO’s view that health is a complex and multifaceted concept that goes beyond just the absence of disease. The WHO’s definition of health encompasses physical, mental and social well-being, recognizing that these three dimensions are closely interconnected and interdependent. This guide will delve into the WHO’s definition of health, exploring its history, significance and implications for individuals and societies.
What is Health According to the WHO?
The Historical Evolution of Health Definitions
The concept of health has evolved over time, and various organizations have provided definitions of health that reflect the changing social, economic, and scientific contexts of their times. The World Health Organization (WHO) has played a significant role in shaping the global understanding of health, and its definition of health has evolved since the organization’s founding in 1948.
The earliest definition of health by the WHO in 1948 described health as “a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.” This definition emphasized the importance of physical, mental, and social aspects of health and highlighted the need for a holistic approach to healthcare.
In 1956, the WHO adopted a broader definition of health that emphasized the role of social and environmental factors in health. The definition stated that health was “a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity, achieved through a combination of physical, mental, and social measures.” This definition acknowledged that health is not just an individual concern but also a collective one, and that social and environmental factors can significantly impact health outcomes.
The WHO’s definition of health continued to evolve in the 1980s, with a focus on primary healthcare and the need to address social determinants of health. The 1986 Ottawa Charter for Health Promotion, developed by the WHO, emphasized that health is “a resource for everyday life, not the objective of living. Health is defined as physical, mental, and social well-being, and not just the absence of disease or infirmity.” This definition recognized that health is a resource that enables individuals to lead fulfilling lives and that addressing social determinants of health is essential for promoting health and well-being.
In 2002, the WHO launched the Millennium Development Goals (MDGs), which aimed to reduce poverty and improve health outcomes in developing countries. The MDGs highlighted the importance of addressing social determinants of health, such as poverty, education, and access to healthcare, in achieving health-related goals.
Today, the WHO’s definition of health emphasizes the importance of addressing not only individual health needs but also the broader social, economic, and environmental factors that impact health outcomes. The WHO recognizes that health is a complex and multifaceted concept that requires a comprehensive and holistic approach to achieve optimal health outcomes for individuals and communities.
The WHO’s Current Definition of Health
The World Health Organization (WHO) defines health as a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity. This definition, established in 1948, emphasizes that health is a holistic concept that encompasses not only the biological aspect but also the psychological and social dimensions of a person’s life.
According to the WHO, health is not merely the absence of disease or illness, but rather a dynamic process that encompasses physical, mental, and social well-being. The organization recognizes that health is influenced by a wide range of factors, including genetics, lifestyle, environment, and access to healthcare.
The WHO’s definition of health has evolved over time to reflect a more comprehensive understanding of the factors that contribute to a person’s overall well-being. In the past, health was often defined in terms of the absence of disease or infirmity, but this approach was found to be too narrow and incomplete. The current definition of health recognizes that physical health is just one aspect of overall well-being and that mental and social health are equally important.
Overall, the WHO’s definition of health is a comprehensive and holistic approach that emphasizes the importance of addressing the full range of factors that contribute to a person’s well-being. By recognizing the interplay between physical, mental, and social health, the WHO’s definition provides a framework for promoting health and preventing disease at both the individual and population levels.

Common mental health disorders include depression, anxiety, bipolar disorder, schizophrenia, and substance use disorders. These disorders can have a significant impact on an individual’s daily life, including their ability to work, maintain relationships, and participate in social activities.
It is important to note that mental health is often stigmatized, and individuals may be reluctant to seek help due to fear of judgment or discrimination. Therefore, it is crucial to promote mental health awareness and reduce the stigma associated with mental health disorders.
Prevention and treatment of mental health disorders involve a multi-faceted approach, including early intervention, psychotherapy, medication, and social support. Additionally, promoting mental health through positive coping strategies, healthy lifestyle choices, and social connections can also contribute to overall mental well-being.
In conclusion, mental health is a critical component of overall health, and it is essential to prioritize mental well-being as part of a comprehensive approach to health. By understanding the importance of mental health and promoting awareness and support, we can work towards creating a society that values and prioritizes mental health for all individuals.
Social health is one of the five dimensions of health identified by the World Health Organization (WHO). It refers to the ability of individuals to interact positively with others and participate in their communities. In other words, social health is the ability to establish and maintain positive relationships with others, to contribute to the well-being of one’s community, and to be actively engaged in social activities.
There are several factors that contribute to social health, including:
- Emotional well-being: The ability to express one’s emotions and feelings in a healthy and constructive manner, and to maintain positive relationships with others.

Critiques and Controversies Surrounding the WHO’s Definition of Health
Critiques of the Current Definition
Despite its broad acceptance, the WHO’s definition of health has faced various critiques and controversies over the years. One of the primary concerns revolves around the lack of specificity in the definition, which has led to ambiguity and confusion.
Ambiguity and Confusion
Critics argue that the WHO’s definition of health is too broad and lacks a clear operational definition. This ambiguity makes it difficult to develop and implement effective health policies and interventions, as it is unclear what specific aspects of health should be prioritized. The lack of specificity also hinders the comparison of health outcomes across different populations and over time, as different stakeholders may prioritize different aspects of health.
Overemphasis on Physical Health
Another critique of the current definition is that it overemphasizes physical health at the expense of mental and social well-being. Critics argue that the definition should be expanded to include mental and social health, as these aspects are equally important for overall health and well-being.
Limited Focus on Social Determinants of Health
Additionally, the current definition has been criticized for its limited focus on individual behavior and lifestyle factors, while ignoring the significant role that social determinants of health play in shaping health outcomes. Critics argue that the definition should be expanded to include the social, economic, and environmental factors that influence health, such as poverty, inequality, and access to healthcare services.
Lack of Cultural Sensitivity
Finally, the current definition has been criticized for its lack of cultural sensitivity, as it does not account for the diverse cultural and societal factors that influence health beliefs and practices. Critics argue that the definition should be more inclusive and culturally sensitive, taking into account the unique health perspectives and needs of different populations.
In conclusion, while the WHO’s definition of health has been widely accepted and influential, it has also faced various critiques and controversies. These critiques highlight the need for a more comprehensive and inclusive definition of health that takes into account the diverse aspects of health, including mental and social well-being, social determinants of health, and cultural sensitivity.
Alternative Definitions and Frameworks
Despite the WHO’s definition of health being widely accepted and utilized, there are alternative definitions and frameworks that have been proposed by various scholars and organizations. These alternative definitions and frameworks offer different perspectives on what constitutes health and well-being, and some have been criticized for being too narrow or too broad in their scope.
One of the most prominent alternative definitions of health is the biomedical model, which focuses primarily on the physical and biological aspects of health. Proponents of this model argue that health is the absence of disease or infirmity, and that the goal of healthcare should be to diagnose and treat illnesses and injuries.
Another alternative definition of health is the holistic model, which emphasizes the importance of social, emotional, and spiritual well-being in addition to physical health. This model recognizes that health is a multidimensional concept that encompasses various aspects of a person’s life, including their relationships, environment, and sense of purpose.
Social Determinants of Health Framework
A third alternative framework is the social determinants of health, which focuses on the social, economic, and environmental factors that influence health outcomes. This framework acknowledges that health is not just a matter of individual behavior or lifestyle choices, but is also shaped by broader social and economic forces such as poverty, discrimination, and access to resources.
Each of these alternative definitions and frameworks has its own strengths and weaknesses, and they are often used in different contexts and for different purposes. Ultimately, the choice of definition or framework will depend on the specific goals and priorities of the individual or organization using it.
The Debate Over Prioritizing Specific Components of Health
The World Health Organization’s definition of health has been the subject of much debate and controversy. One of the key areas of contention is the prioritization of specific components of health. Some argue that the WHO’s definition is too broad and fails to prioritize certain aspects of health that are critical to well-being.
One of the main criticisms of the WHO’s definition is that it does not prioritize physical health over mental health. Critics argue that physical health is a critical component of overall well-being and should be given greater emphasis in the definition of health. They contend that without a clear focus on physical health, the WHO’s definition may not adequately address the needs of individuals who suffer from chronic illnesses or disabilities.
Another area of debate is the role of social determinants of health. Some argue that the WHO’s definition should place greater emphasis on the social and economic factors that influence health outcomes. They contend that social determinants such as income, education, and access to healthcare are critical to overall well-being and should be prioritized in the definition of health.
Finally, there is debate over the role of personal responsibility in the WHO’s definition of health. Some argue that individuals have a responsibility to maintain their own health and that this should be reflected in the definition. They contend that without a clear emphasis on personal responsibility, the WHO’s definition may not encourage individuals to take an active role in maintaining their own health.
Despite these criticisms, the WHO’s definition of health remains a widely accepted framework for understanding health and well-being. However, as the debate over prioritizing specific components of health continues, it remains to be seen how the definition will evolve to better reflect the changing needs and priorities of individuals and communities around the world.
The Future of Health and the WHO’s Definition
Emerging Trends in Health and Well-being
In recent years, there has been a growing awareness of the importance of mental health and well-being in addition to physical health. This shift in focus has led to the emergence of several new trends in health and well-being.
One of the most significant trends is the increasing recognition of the importance of social determinants of health. These are the conditions in which people are born, grow up, live, work, and age, including factors such as income, education, and housing. The WHO has recognized that these factors have a significant impact on health outcomes and has emphasized the need for a more holistic approach to health that takes into account the social determinants of health.
Another trend that has emerged is the growing use of technology in healthcare.

This would acknowledge the significant impact that factors such as air and water pollution, climate change, and access to green spaces have on individual and population health.
Social Determinants of Health
A third potential revision to the WHO’s definition of health could incorporate a greater focus on social determinants of health. This would acknowledge the significant impact that social factors such as income, education, and access to healthcare have on health outcomes.
Finally, some have proposed revising the WHO’s definition of health to include a more personalized approach to healthcare. This would recognize that individuals have unique health needs and that health outcomes are influenced by a wide range of factors, including genetics, lifestyle, and environment.
In conclusion, the potential revisions to the WHO’s definition of health reflect a growing recognition of the complex and multifaceted nature of health outcomes. As the global health landscape continues to evolve, it is likely that the WHO’s definition of health will be revised to better reflect the changing needs of populations around the world.
The Importance of a Dynamic Definition
The World Health Organization’s definition of health has evolved over time, and it is crucial to understand the importance of a dynamic definition in today’s rapidly changing world. A dynamic definition of health acknowledges that health is not a static state but a constantly changing process influenced by various factors such as environmental, social, economic, and political changes.
One of the primary reasons why a dynamic definition of health is important is that it emphasizes the need for a holistic approach to health. This approach considers not only the physical well-being of individuals but also their mental, social, and environmental health. A dynamic definition of health recognizes that these factors are interconnected and interdependent, and they all contribute to overall health and well-being.
Another reason why a dynamic definition of health is crucial is that it encourages a proactive approach to health. Instead of waiting until a person becomes sick or develops a disease, a dynamic definition of health emphasizes the importance of taking preventative measures to maintain and improve health. This includes adopting healthy lifestyles, promoting mental health, and reducing exposure to environmental hazards.
Additionally, a dynamic definition of health recognizes the role of social determinants of health. Social determinants of health refer to the conditions in which people are born, grow, work, and age. These conditions include factors such as income, education, employment, housing, and social support networks. A dynamic definition of health acknowledges that these social determinants have a significant impact on an individual’s health and well-being, and addressing them is essential to promoting health equity.
Finally, a dynamic definition of health acknowledges the importance of participatory approaches to health. This approach involves engaging individuals and communities in decision-making processes related to their health. Participatory approaches to health promote empowerment, ownership, and accountability, leading to better health outcomes.
In conclusion, a dynamic definition of health is crucial in today’s rapidly changing world. It emphasizes the need for a holistic approach to health, encourages a proactive approach to health, recognizes the role of social determinants of health, and promotes participatory approaches to health. By adopting a dynamic definition of health, we can work towards creating a healthier and more equitable world for all.
