Ask ten people what it means to be healthy, and you will likely hear ten different answers. Some will say it is the absence of disease, others will talk about gym routines, mental peace, or even financial stability. Health, as it turns out, is far more layered than a clean bill from the doctor. It is a dynamic state shaped by biology, emotions, relationships, and the society around us. Understanding what truly constitutes health and how we measure it is the first step toward building healthier individuals, families, and communities.

Defining health holistically: beyond the absence of disease
For most of human history, health was understood narrowly as the absence of illness. If you were not coughing, bleeding, or bedridden, you were considered healthy. This biomedical view dominated thinking until 1948, when the World Health Organization (WHO) introduced a definition that changed how the world looked at well-being. According to the WHO Constitution, health is “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.”
This definition was revolutionary for two reasons. First, it framed health as a positive state rather than a neutral one. Being healthy is not just about not being sick; it is about actively flourishing. Second, it expanded the boundaries of health to include the mind and the social environment, paving the way for what we now call the biopsychosocial model, which considers physiological, psychological, and social factors together.
The definition has not been without critics. Some argue that demanding “complete” well-being is unrealistic and leaves most people unhealthy most of the time, especially those living with chronic illnesses or disabilities. However, a closer reading suggests the word “complete” was meant qualitatively, referring to exhaustive well-being containing all its constitutive features, not a utopian state of perfection. In 1986, the Ottawa Charter refined this idea further by describing health as “a resource for everyday life, not the object of living”-a means to live well rather than an end in itself.
The components of health
Holistic health is best understood by breaking it down into its core dimensions. These dimensions are not isolated silos; they constantly interact, influence, and shape one another. A breakdown in one often triggers ripple effects in the others.
Physical health
Physical health refers to the proper functioning of the body and its systems. It is influenced by genetics, nutrition, sleep, physical activity, hygiene, and access to medical care. A person with good physical health typically has the energy to perform daily tasks, the strength to resist common illnesses, and the resilience to recover from injuries or stressors. In a country where lifestyle diseases like diabetes, hypertension, and cardiovascular conditions are rising sharply, physical health has become a public priority. The National Health Portal emphasizes balanced nutrition, regular activity, and preventive screenings as the foundations of physical well-being.
Mental health
Mental health is often misunderstood as simply the absence of mental illness, but the WHO clearly states that mental health is more than just the absence of mental disorders. It is a state in which an individual recognises their abilities, copes with the normal stresses of life, works productively, and contributes meaningfully to their community. Mental health is shaped by socioeconomic conditions, biological predispositions, life experiences, and the environment.
Anxiety, depression, and stress-related conditions have become increasingly visible among college students, working professionals, and even adolescents. Stigma still prevents many from seeking help, but initiatives like the National Mental Health Programme and the Tele MANAS helpline are working to make support more accessible. Importantly, there is no health without mental health-the two are inseparable.
Social health
Social health refers to a person’s ability to form meaningful relationships, communicate effectively, adapt to social situations, and feel a sense of belonging. Humans are social beings, and isolation has been shown to harm both mental and physical health. Strong family bonds, supportive friendships, community participation, and a sense of inclusion all contribute to social well-being.
In a society where joint family systems are gradually giving way to nuclear units, where migration to cities is common, and where digital interactions often replace face-to-face conversations, social health deserves special attention. Loneliness, social anxiety, and a weakening of community ties are emerging concerns that public health professionals are only beginning to address seriously.
Sexual health
Sexual health is a dimension that has long been wrapped in silence, especially in conservative cultures. The WHO defines sexual health as “a state of physical, emotional, mental and social well-being in relation to sexuality; it is not merely the absence of disease, dysfunction or infirmity.” It requires a positive and respectful approach to sexuality and sexual relationships, the possibility of having pleasurable and safe experiences free from coercion, discrimination, and violence.
Sexual health goes well beyond avoiding sexually transmitted infections or unintended pregnancies. It includes the right to information, consent, bodily autonomy, and freedom from stigma. For young adults in particular, accurate sexual education and access to non-judgmental healthcare are essential. Programmes under the National AIDS Control Organisation and the Rashtriya Kishor Swasthya Karyakram aim to address adolescent and reproductive sexual health, though significant gaps in awareness and access still exist.
Measuring well-being: indicators of health
If health is so multidimensional, how do we actually measure it? This is where health indicators come in. According to IGNOU’s public health materials, health indicators are variables that help measure changes in the health status of a population. A good indicator should be valid, reliable, sensitive, specific, feasible, and relevant. They allow governments, researchers, and healthcare providers to track progress, identify gaps, and make informed decisions about resource allocation.
Objective indicators
Objective indicators are quantifiable measures that can be observed, tested, or recorded externally. They include:
Mortality indicators such as the Infant Mortality Rate (IMR), Maternal Mortality Ratio (MMR), Under-Five Mortality Rate, and life expectancy at birth. These reveal a great deal about the quality of healthcare services and overall living conditions. India’s IMR, for instance, has dropped significantly over the decades but still varies widely across states.
Morbidity indicators measure the incidence and prevalence of diseases-how common tuberculosis, diabetes, anaemia, or mental health disorders are in a population. Nutritional indicators track stunting, wasting, underweight prevalence, and micronutrient deficiencies, which the National Family Health Survey documents periodically. Healthcare delivery indicators assess doctor-to-population ratios, hospital beds, and immunization coverage, while environmental indicators look at access to safe drinking water, sanitation, and air quality.
Subjective indicators
Subjective indicators capture how people themselves perceive their health and quality of life. Self-rated health (SRH), where individuals rate their own health on a scale, is one of the most widely used subjective measures. Surprisingly, self-perception can sometimes diverge sharply from clinical reality. A study using the Longitudinal Aging Study in India found that older Indians tend to report more positive perceptions of their health than objective measures of grip strength and lung function would suggest. This gap reveals something important: subjective and objective indicators capture different aspects of health, and both are needed for a complete picture.
Other subjective measures include life satisfaction scales, psychological well-being indices, and tools like the WHO-5 Well-Being Index. These help capture dimensions that lab tests simply cannot-happiness, sense of purpose, fulfilment, and emotional balance.
Cultural variations in defining well-being
What counts as “well-being” is not universal. Cultural values, religious beliefs, and social norms shape how people understand a good life. In many Asian cultures, well-being is closely tied to family harmony, fulfilling social roles, and intergenerational respect. In contrast, Western frameworks often emphasize individual autonomy and personal achievement. Some scholars have even argued for adding a spiritual dimension to the WHO definition, recognising that for many communities, faith and inner peace are central to health.
This cultural variation matters because a one-size-fits-all framework can miss what truly makes people feel healthy. A rural farmer’s sense of well-being may be tied to a good monsoon and the health of her cattle, while an urban professional’s may revolve around career growth and work-life balance.
Social justice and the right to health
Health is not just an individual achievement-it is a social and political issue. The WHO has long maintained that the enjoyment of the highest attainable standard of health is a fundamental human right without distinction of race, religion, political belief, or economic and social condition. Yet stark inequalities persist. Caste, gender, income, geography, and education all influence who gets to be healthy and who does not.
Women and girls often face disadvantages in nutrition, access to healthcare, and decision-making power over their own bodies. Tribal communities and rural populations frequently encounter shortages of medical facilities and trained professionals. Migrant workers, sexual minorities, and people with disabilities face their own unique barriers. A social justice perspective on health asks us to look beyond individual lifestyle choices and confront the structural conditions-poverty, discrimination, lack of education, environmental degradation-that shape health outcomes.
This is why India’s National Health Policy emphasizes universal access, equity, and the social determinants of health alongside clinical interventions. Achieving genuine well-being for all requires not just better hospitals, but fairer societies.
Why all of this matters
Understanding health holistically and measuring it accurately has practical consequences. It influences how governments allocate budgets, how schools design curricula, how workplaces support employees, and how families make everyday decisions. When we reduce health to physical fitness alone, we ignore the silent epidemic of mental illness and the corrosive effects of social isolation. When we rely only on objective indicators, we miss how people actually experience their lives. And when we ignore social justice, we end up with healthcare systems that work well for some and fail many.
The journey toward holistic health begins with awareness-of our bodies, our minds, our relationships, and the larger systems we live within. It also begins with the recognition that being healthy is not a destination but an ongoing, dynamic process.
What do you think? Which dimension of health do you feel is most overlooked in your own community, and how might cultural context change the way we define a “healthy” life?
