Which Definition Best Defines Health?

Introduction

Health is a foundational concept in human life. It influences our quality of life, productivity, relationships, and longevity. But what does it really mean to be healthy? Is it simply living without disease? Or is it something more?

Over time, multiple definitions of health have emerged—from the narrow biomedical perspective to broader, more holistic models. Each definition offers different insights and limitations. In this essay, we will critically examine the major definitions of health and ultimately argue that the World Health Organization’s (WHO) holistic definition, though not perfect, remains the most comprehensive and useful in capturing the full meaning of health.

1. The Biomedical Definition of Health

Definition:
The biomedical model defines health as the absence of disease, pain, or physical abnormality. This is the most traditional and widely applied definition in modern Western medicine.

Strengths:

• Simple and measurable: Disease can be identified, treated, and managed.

• Compatible with medical diagnostics and interventions.

• Useful for acute and infectious disease management.

Limitations:

• It views the human body as a machine to be fixed rather than as a whole person with physical, emotional, and social dimensions.

• Ignores mental and emotional health, lifestyle, and environmental factors.

• Offers little in terms of health promotion or disease prevention.

Example:
A person who has no physical symptoms but suffers from severe depression or chronic anxiety may still be considered “healthy” under the biomedical model. Clearly, this is a limited understanding of health.

2. The World Health Organization (WHO) Definition

Definition (1948):

“Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.”

Strengths:

• Holistic approach: Recognizes that health is more than physical. It includes mental and social aspects.

• Human-centered: Acknowledges that well-being matters, not just the presence or absence of symptoms.

• Progressive and forward-thinking: At the time of its adoption, it radically shifted global health thinking.

Limitations:

• The word “complete” has been criticized as being unrealistic. How many people are ever in a state of complete well-being?

• It can medicalize normal human experiences—e.g., temporary sadness or minor stress may be seen as health failures.

• Critics argue it sets a perfect ideal that may be unattainable for most.

Why it’s still valuable:
Despite criticisms, this definition expanded the conversation around health. It was the first mainstream definition to include mental and social well-being—now recognized as essential. It paved the way for more integrated, community-based, and preventative models of health.

3. The Ottawa Charter for Health Promotion (1986)

Definition:
Health is defined as:

“A resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities.”

Strengths:

• Functional and dynamic: Recognizes health as a resource, not a static state.

• Emphasizes empowerment, capacity, and the ability to live a fulfilling life.

• Encourages a public health perspective—health promotion, prevention, and community support.

Limitations:

• Some argue this definition is too vague or abstract.

• It shifts focus away from illness, which might make it harder to address people in actual poor health.

• Less emphasis on measurable outcomes, which healthcare systems often rely on.

Why it’s influential:
This definition is central to public health policy today. It’s particularly effective in community health, education, and global health development. It moves beyond individual care to societal well-being and collective responsibility.

4. Huber’s “New” Definition of Health (2011)

Definition:

“Health is the ability to adapt and self-manage in the face of social, physical, and emotional challenges.”

Strengths:

• Realistic and flexible: Acknowledges that health is not a perfect state, but an ongoing process of resilience and adaptation.

• Applicable to chronic illness: People living with long-term conditions can still be considered healthy if they are managing well.

• Shifts focus from “cure” to “coping,” emphasizing resilience and quality of life.

Limitations:

• May downplay suffering if people are expected to “adapt” to poor health or limited resources.

• Might be hard to operationalize in medical settings—how do we measure “adaptability”?

• Could be interpreted as shifting responsibility onto individuals, overlooking social determinants of health.

Why it’s relevant:
In an age where chronic illness, mental health, and aging are increasingly common, Huber’s definition reflects the real-life experience of many people. It helps reframe conversations around disability, long-term care, and aging populations.
