Environment and human health: A holistic perspective

During the 20th century, the system of scientific medicine has made dramatic progress in curing and reducing the incidence of many diseases. There has been massive reduction in death rates all over the world resulting from the achievements of scientific medicine. It has been possible to bring forth a large number of highly effective drugs that have been discovered through painstaking medical research. This has also brought about significant improvement in public health and hygiene.
However, the modern scientific medicine has not proved very effective in handling a whole area of chronic illness and general, not very well defined, ill health. It is now increasingly being realized that scientific medicine is not very successful in addressing the problems of ill health having their roots in a person’s psychosomatic, social, cultural, behavioural or occupational environment. It is becoming increasingly clear that despite dramatic advancements the system of scientific medicine has serious limitations because it does not take into account the environment of human existence, functioning and life as integral to human health. Merely studying the ‘causes’ of some human health problems in the environmental conditions or pollution and finding curative remedies for these is an extremely narrow view of the relationship between environment and human health.
The primitive tribes as well those societies that have retained their unbroken linkage with their ancient past still have an instinctive holistic view, which is derived from intimate knowledge of the local ecosystems in their environments. Each such society treats the local ecosystem as dominant and makes all human activities subservient to it. This approach to environment and human life is still observed in ancient and oriental civilizations.
The holistic thinking continued in the western world also in some or the other form till the Renaissance Period. However, with the rise of scientific movement in the mid-17th century, the materialistic-mechanistic worldview and the reductionist approach to analysis became dominant. This led to shifting of focus from the whole to parts and the holistic thinking was gradually abandoned in the mainstream western worldview. As a consequence, non-holistic nature of much of the modern education leaves most the educated people with conceptual frameworks that are too narrow to allow holistic thinking. However, in recent times, there has been a decline in mechanistic-reductionist thinking as its limitations have become more and more apparent. Many attempts are being made now to build a synthesis of ideas and evolve holistic paradigms in every field, including human health.
In the context of human life, the shift from reductionist to holistic thinking may be seen in the words of Peter Russell (1982) “For humanity to accomplish a profound shift in attitude, the skin-encapsulated model of the self needs to be augmented by the realization that the individual is an integral part of Nature, no more isolated from the environment than a cell in the body is isolated from the human organism.”
Arthur Koestler (1979) in rejecting the reductionist philosophy developed the concept of ‘HOLON’ as a system consisting of subsystems, which is also a subsystem of some supersystem. He further developed the concept of SOHO (Self-regulating Open Hierarchic Order), which is an explanation of a form of dynamic equilibrium (‘homeostasis’) that will occur only if the self-assertive and integrative tendencies of the components of holons counterbalance each other. If this does not happen, there will be disorder and chaos. His theory has profound implications for society and for understanding human health.
In the last quarter of 20th century, it has been gradually realized that before we can devise ways and means for making and maintaining a human being healthy, it is necessary to first understand what is to be accomplished. This means that we should first understand the meaning of human health.
Jonas Salk (1972) in defining the health asserts that “The health is wholeness and sickness implies impairment of parts of the whole. Distinctions must be made and the relationship understood between the parts and the whole, so that attention may then be directed to maintaining or to repairing the health of each appropriately. The meaning of the health as a wholeness can be revealed only if distinction between the parts and the whole and the relationship between them is properly understood.” He has further pointed out that for developing a system of holistic health, it is necessary to first think about the mankind in terms of highly ordered, differentiated system of individuals having widely different attributes, characteristics and requirements. Only by thinking in these terms, it can be possible to focus attention on the relationship between the parts i.e. the individuals and the whole; the whole in this context meaning the human species. An understanding of the relationship of individuals to each other and to the whole mankind is the starting point. This shall lead to the comprehension that human health is not merely a question of the health of one part to the exclusion of another or of one part functioning against another, but as the health of the whole. This view thus, clearly emphasizes the relevance of social environment in the problem of human health. It also points out that the problem of man’s health can not be dealt with by solving only the problems of individual human body and its environment. Even if these problems are solved, it will still be necessary to deal with the health of the human species as a whole and its global environment.
To achieve a state of health, it is definitely necessary to understand the development and functioning of cells and organs. However, in the broadest sense, it is also necessary that we understand the development and functioning of an individual in his/her personal physical, psychological, familial, occupational, cultural and social environment as well as of the human species in the global environment. If total health potential of an individual is to fully manifest, the state of full health must prevail not only in the individual but also in mankind and most importantly in the global environment too.
To conclude, it may be pointed out that an individual human being can attain and maintain a state of his/her full potential of physical, emotional, intellectual and spiritual health only in a healthy environment that comprises his/her particular biosphere, sociosphere and psychosphere as well as whole global environment of human species. In this sense, human species needs to be studied along with all aspects of its environment i.e. from the viewpoint of health as wholeness of Nature. A science of holistic health, as distinct from the present science of curative medicine, needs to be developed to deal with the problems of sickness and misery arising in the bodies, psyche, society and environment of mankind. This would first of all require a shift of medical education paradigm away from the current mechanistic-reductionist one towards a holistic one.
