In recent years, the definition of health and well-being has expanded to include not just the absence of sickness, but also a comprehensive condition of physical, mental, and social well-being. This shift reflects an increasing realization that health is influenced by a complex interaction of factors. Dr. George L. Engel’s 1977 developed Bio-psycho-social model, which combines biological, psychological, and social elements, has played an important role in this paradigm shift. Introducing an environmental viewpoint to this paradigm, establishing what we now call the bio-psycho-social-green model, provides an even more comprehensive framework for understanding health and well-being in the modern era. This article delves into the components of this paradigm and how they interact to influence health outcomes.
Biological Element

The biological aspect of the bio-psycho-social-green model includes genetic predispositions, neurobiological mechanisms, and physiological processes. These factors lay the foundation for understanding how our bodies function and respond to internal and external stimuli.
Genetics and Health
Genetic factors play a crucial role in determining an individual’s susceptibility to various health conditions. For example, certain genetic mutations can increase the risk of developing chronic diseases like diabetes, heart disease, and cancer. Understanding these genetic predispositions can help in early detection and personalized treatment plans.
Neurobiology
The brain and nervous system are central to the biological dimension of health. Neurobiological processes influence mental health conditions such as depression, anxiety, and schizophrenia. Advances in neuroimaging and neurobiology have enhanced our understanding of how brain structure and function are related to behaviour and mental health.
Physiological Processes
Physiological processes, including hormonal regulation, immune function, and metabolic processes, are essential for maintaining health. Disruptions in these processes can lead to various health issues. For instance, chronic inflammation is linked to several diseases, including autoimmune disorders and cardiovascular diseases.
Psychological element
The psychological component of the model focuses on mental health, emotions, thoughts, behaviors, and cognitive processes. It explores how these factors influence overall well-being and how they interact with biological and social dimensions.
Mental Health
Mental health is a critical aspect of overall health. Conditions such as depression, anxiety, bipolar disorder, and post-traumatic stress disorder (PTSD) can significantly impact an individual’s quality of life. Psychological therapies, such as cognitive-behavioral therapy (CBT), have been effective in treating these conditions by addressing maladaptive thought patterns and behaviours.
Emotions and Behaviour
Emotions play a vital role in how individuals perceive and respond to their environment. Positive emotions, such as joy and contentment, are associated with better health outcomes, while negative emotions, such as anger and sadness, can contribute to health problems. Behavioral interventions can help individuals develop healthier coping mechanisms and improve their emotional well-being.
Cognitive Processes
Cognitive processes, including perception, memory, and decision-making, are integral to mental health. Cognitive dysfunction can result from various factors, including neurodegenerative diseases, brain injuries, and psychological conditions. Cognitive rehabilitation and therapy can aid in restoring cognitive function and enhancing mental health.
Social element
The social dimension emphasizes the impact of social relationships, community, cultural norms, and socio-economic status on health. It highlights the importance of social support and community engagement in promoting well-being. Keeping the social element in mind the WHO world health organisation announced a novel commission on social connections in 2023. It is observed that high rates of social isolation and loneliness have negative repercussions on the health wellbeing of a person. The people without strong and quality social connections are prone and high risk of stroke, anxiety dementia, depression, suicide (WHO Director General Dr Tedros ).
Social Relationships
Strong social connections are associated with better health outcomes. Social support from family, friends, and community can provide emotional comfort, practical assistance, and a sense of belonging. Conversely, social isolation and loneliness are linked to various health problems, including depression, anxiety, and cardiovascular disease.
Community and Culture
Community and cultural factors significantly influence health behaviors and outcomes. Cultural norms and values can shape health-related behaviors, such as diet, exercise, and healthcare utilization. Community engagement and social cohesion can enhance public health by fostering supportive environments and promoting healthy behaviors.
Socio-Economic Status
Socio-economic status (SES) is a crucial determinant of health. Individuals with higher SES generally have better access to healthcare, education, and resources, leading to improved health outcomes. Conversely, lower SES is associated with increased exposure to health risks and barriers to healthcare access.
Green element
The green dimension adds an environmental perspective to the model, acknowledging the impact of natural and built environments on health. It underscores the importance of environmental sustainability and the role of nature in promoting well-being.
Natural Environments
Access to natural environments, such as parks, forests, and green spaces, has been shown to have numerous health benefits. Exposure to nature can reduce stress, improve mood, enhance cognitive function, and promote physical activity. Green spaces provide opportunities for recreation, social interaction, and relaxation, contributing to overall well-being.
Built Environments
The design and quality of built environments also influence health outcomes. Urban planning, housing quality, transportation systems, and access to amenities can impact physical and mental health. For instance, neighborhoods with safe walking paths, recreational facilities, and access to healthy food options promote active lifestyles and reduce the risk of chronic diseases.
Environmental Sustainability
Environmental sustainability is critical for long-term health and well-being. Pollution, climate change, and resource depletion pose significant threats to public health. Sustainable practices, such as reducing carbon emissions, conserving natural resources, and promoting green technologies, are essential for protecting the environment and ensuring healthy living conditions for future generations.
How it works: interactions between the elements of model
The bio-psycho-social-green model recognizes that health is influenced by the dynamic interactions between biological, psychological, social, and environmental factors. These dimensions do not operate in isolation but are interconnected in complex ways.
Biological and Psychological Interactions
Biological processes can influence psychological well-being, and vice versa. For example, chronic stress can lead to physiological changes, such as increased cortisol levels, which can contribute to physical health problems. Conversely, physical health conditions can impact mental health, leading to conditions such as depression and anxiety.
Psychological and Social Interactions
Psychological well-being is closely linked to social factors. Social support can buffer against stress and enhance resilience, while social isolation can exacerbate psychological distress. Community engagement and social participation can improve mental health by providing a sense of purpose and belonging.
Social and Environmental Interactions
Social factors can influence environmental conditions, and environmental conditions can impact social well-being. For instance, socio-economic disparities can result in unequal access to green spaces and healthy living environments. Conversely, living in polluted or unsafe environments can contribute to social inequalities and health disparities.
Environmental and Biological Interactions
Environmental factors can directly impact biological health. Exposure to pollutants, toxins, and hazardous materials can lead to various health conditions, including respiratory diseases, cancers, and developmental disorders. Conversely, access to clean air, water, and green spaces can enhance biological health and well-being.
Implications for Health Policy and Practice
The bio-psycho-social-green model has significant implications for health policy and practice. It calls for an integrated approach to health promotion, disease prevention, and healthcare delivery that addresses the complex interplay of biological, psychological, social, and environmental factors.
Integrated Healthcare
Integrated healthcare models that incorporate medical, psychological, social, and environmental interventions are essential for addressing the multifaceted nature of health. Collaborative care teams, including healthcare providers, mental health professionals, social workers, and environmental health experts, can deliver comprehensive and coordinated care.
Health Promotion and Disease Prevention
Health promotion and disease prevention strategies should consider all dimensions of the bio-psycho-social-green model. Public health campaigns can raise awareness about the importance of mental health, social support, and environmental sustainability. Community-based programs can promote healthy behaviors, enhance social cohesion, and improve access to green spaces.
Environmental Health
Environmental health policies should prioritize sustainability and address environmental determinants of health. Regulations to reduce pollution, promote clean energy, and ensure access to green spaces are essential for protecting public health. Urban planning and design should focus on creating healthy, sustainable, and inclusive environments.
Research and Education
Research and education should adopt a holistic approach to health. Interdisciplinary research can explore the interactions between biological, psychological, social, and environmental factors. Educational programs can train healthcare professionals to adopt a comprehensive perspective on health and well-being.
Wind – up
The bio-psycho-social-green model offers a complete framework for examining health and well-being. This paradigm emphasises the complex interplay of factors influencing health outcomes by incorporating biological, psychological, social, and environmental elements. It emphasises the value of a comprehensive approach to health promotion, illness prevention, and healthcare delivery. Adopting this model can result in more successful and long-term strategies for improving health and well-being at the individual, community, and societal levels.
