Key Skills (Unit 3)
This revision note covers the essential skills you need to master for Concepts of Health and Wellbeing. These skills focus on explaining key concepts, describing relationships, and understanding the importance of health and wellbeing at individual, national, and global levels.
Understanding the dynamic and subjective nature of health, wellbeing, and illness
To explain the dynamic and subjective nature of health, wellbeing, and illness effectively, you first need to understand what these concepts mean. This forms the foundation for demonstrating your knowledge in assessments.
Defining health and wellbeing
Health and wellbeing is a multidimensional concept that goes beyond simply being free from disease. It encompasses a person's physical, social, emotional, mental, and spiritual state. Good health and wellbeing is characterised by a balance where the individual feels happy, healthy, capable, and engaged in life. Importantly, this is a subjective concept, meaning it varies from person to person based on their circumstances, values, and experiences.
When explaining health and wellbeing, ensure you acknowledge all five dimensions and how they collectively contribute to a person's overall state of existence. Each dimension includes specific characteristics that help define optimal health in that area.
Defining illness
Illness is distinct from disease. Whilst disease refers to a medically diagnosed condition, illness relates to the personal experience of having a disease or injury. It reflects how an individual perceives and experiences their condition, including the symptoms, discomfort, and impact on their daily life.
Understanding the dimensions of health and wellbeing
Each dimension of health and wellbeing has specific characteristics that you should be familiar with. For instance, physical health and wellbeing refers to a state of physical well-being where a person can perform their daily activities without restrictions. This includes aspects such as physical capacity to perform tasks, physical fitness, appropriate body weight, healthy blood pressure levels, and adequate energy levels.
Being able to explain each dimension thoroughly, along with relevant examples, helps you predict potential impacts on health and wellbeing in various scenarios. This skill is essential for success in assessments.
The dynamic nature of health and wellbeing
The term dynamic means that health, wellbeing, and illness are constantly changing. These concepts are not fixed states but rather fluctuate based on various circumstances and events in a person's life. Changes can occur gradually over time or very rapidly depending on the situation.
Several types of events can trigger changes in health and wellbeing:
- Recovery from disease: When someone experiencing high levels of illness receives effective medical treatment, their symptoms may decrease, pain may reduce, and energy levels may increase. This improvement in physical health and wellbeing leads to a corresponding decrease in their experience of illness.
- Forming new relationships: An individual with limited social connections may experience poor social health and wellbeing. Making new friends creates opportunities for social interaction, which can significantly improve their social health and wellbeing.
- Personal achievement: Success at school, work, or in community activities can enhance emotional health and wellbeing by promoting feelings of pride. Achievements can also boost self-esteem, which is a key component of mental health and wellbeing.
- Community participation: Becoming involved in community activities, such as volunteering, can create a sense of belonging and purpose. This connection to the broader community can significantly enhance spiritual health and wellbeing.
Conversely, negative events such as infections, conflicts, bereavement, social isolation, or persistent sadness can cause deterioration across multiple dimensions of health and wellbeing, demonstrating how dynamic these concepts truly are.
An individual's perception of health, wellbeing, and illness also changes throughout their life. Factors such as age, disease status, living conditions, employment circumstances, and energy levels all influence how someone views these concepts at any given time. This changeability reflects both the dynamic and subjective nature of health and wellbeing.
The subjective nature of health and wellbeing
The term subjective indicates that health, wellbeing, and illness mean different things to different people. Each person's definition and priorities regarding health are shaped by their unique circumstances, life stage, values, and experiences.
For example, a student might view health and wellbeing primarily in terms of their ability to complete schoolwork successfully and maintain friendships. In contrast, a parent might define health and wellbeing based on their capacity to provide for their family and manage household responsibilities effectively. Neither perspective is more correct than the other; they simply reflect different life contexts and priorities.
The subjective nature of illness is equally important to understand. An individual with a high pain threshold might not consider themselves ill unless they are completely unable to function normally, regardless of whether they have a diagnosed disease. Meanwhile, someone with a low pain threshold might perceive themselves as experiencing significant illness even with minor health conditions. These different perceptions demonstrate how illness is experienced subjectively.
Exam tips:
- When explaining these concepts, avoid definitions that are too narrow. Always acknowledge the multidimensional nature of health and wellbeing.
- Practice using these terms frequently to gain confidence in when and how to apply them correctly.
- Ensure you can provide specific examples that demonstrate both the dynamic and subjective nature of these concepts.
- Remember that all dimensions of health and wellbeing are interconnected, so changes in one area often affect others.
Describing interrelationships between dimensions of health and wellbeing
The five dimensions of health and wellbeing are deeply interconnected. Understanding these interrelationships is crucial for predicting how changes in one dimension can create ripple effects across others.
Mastering the skill of describing interrelationships
To effectively describe interrelationships, you must first be able to explain each dimension clearly and identify specific characteristics associated with optimal health in each area. Practising with case studies and real-life examples helps develop this skill.
When faced with an unfamiliar scenario in an assessment, a useful strategy is to start by identifying an impact on one dimension and then systematically work through how this might affect the other dimensions. Begin with the dimension you find easiest to link, and remember that all five dimensions will be affected in some way, including the one where the initial impact occurred.
Working through an example
Worked Example: Brooke's Relationship Breakup
Consider Brooke's situation: she has recently ended a six-month relationship and is feeling upset and anxious. During the relationship, she became close with her boyfriend's friends and now feels she has neglected her own friendships. She worries it may be difficult to reconnect with her old friends.
Emotional health and wellbeing: Brooke is experiencing negative emotions such as upset and anxiety following her breakup. These feelings are direct impacts on her emotional health and wellbeing.
Physical health and wellbeing: Because Brooke feels upset and anxious, she may not be eating properly or maintaining her usual exercise routine. This disruption could affect her fitness levels and body weight over time. Poor nutrition and lack of exercise would represent a decline in her physical health and wellbeing.
Mental health and wellbeing: If Brooke gains weight as a result of changed eating and exercise habits, she might develop negative feelings about her body. This could decrease her self-esteem, which is a key aspect of mental health and wellbeing. Lower self-esteem creates another layer of impact beyond the initial emotional distress.
Social health and wellbeing: With decreased self-esteem, Brooke may lack the confidence to reach out to her old friends and re-establish those connections. This reluctance to engage socially means her social health and wellbeing could suffer, as she may experience loneliness and reduced social interaction.
Spiritual health and wellbeing: Without meaningful relationships and social connections, Brooke may feel disconnected from her community and the world around her. This lack of belonging and purpose represents a decline in spiritual health and wellbeing.
Back to emotional health and wellbeing: The combination of physical changes, low self-esteem, social isolation, and lack of belonging could intensify Brooke's emotional state, potentially leading to deeper feelings of sadness and despair. This demonstrates how impacts can cycle back and compound the original dimension affected.
This example shows how an initial impact on one dimension (emotional health and wellbeing) can cascade through all other dimensions, with each change potentially triggering further effects. The interrelationships create a complex web of impacts that can either support or undermine overall health and wellbeing.
Exam tips:
- When answering questions about interrelationships, try to address multiple dimensions, even if the question doesn't specify how many to include.
- Always link your examples explicitly to the specific dimension of health and wellbeing being affected.
- Use connecting language to show how one impact leads to another (e.g., "This could lead to...", "As a result...", "This may cause...").
- Remember that both positive and negative changes can create interrelationships between dimensions.
Explaining health and wellbeing as a resource
Health and wellbeing function as a valuable resource at both individual and collective levels. Understanding this concept requires making clear connections between optimal health and wellbeing and the positive outcomes they enable.
Understanding optimal health and wellbeing
Before explaining health and wellbeing as a resource, you need to identify the characteristics of optimal health and wellbeing for each dimension. For example, optimal mental health and wellbeing includes low stress levels, high self-esteem, positive thought patterns, and strong confidence. Knowing these characteristics allows you to demonstrate how they translate into tangible benefits.
Health and wellbeing as an individual resource
When health and wellbeing are optimal, individuals are better positioned to achieve their goals and improve their quality of life. Consider how optimal mental health and wellbeing creates opportunities:
- Low stress levels allow individuals to concentrate on activities that enhance their life, such as studying, working productively, or socialising with friends and family. Reduced stress also supports physical health by improving immune system function, which decreases the risk of infectious diseases. This means individuals spend less money on healthcare costs like doctor's consultations and medications, preserving their financial resources for other needs.
- High self-esteem motivates people to perform at their best in all areas of life, including their work. Better work performance can lead to career advancement and higher income. This additional income serves as a resource that can be used for healthcare, nutritious food, adequate housing, and social activities, all of which further enhance quality of life.
- Positive thought patterns reduce the risk of developing mental illnesses such as depression and anxiety. Avoiding these conditions means individuals can maintain their productivity and avoid the personal costs associated with treatment and time off work.
- Confidence encourages individuals to embrace challenges and try new experiences. This willingness to take calculated risks can lead to personal growth, new opportunities, and even the development of innovative business ideas that increase personal income.
Demonstrating the link to individual benefits
Let's examine how optimal physical health and wellbeing acts as a resource for individuals. When someone experiences optimal physical health and wellbeing, they are less likely to suffer from infectious or chronic conditions. With fewer health problems, they are better able to maintain employment and earn a stable income. This income then becomes a resource that provides access to essential needs such as food, shelter, clothing, and healthcare.
The benefits extend beyond meeting basic needs. Adequate income also reduces financial stress, which supports mental health and wellbeing. Having the energy and physical capacity to socialise enhances both physical and social health and wellbeing. Feeling capable of meeting one's responsibilities and supporting oneself or one's family promotes a sense of purpose, which strengthens spiritual health and wellbeing. These achievements can generate positive emotions like satisfaction and contentment, boosting emotional health and wellbeing.
This example illustrates how optimal health in one dimension (physical) provides resources that support all other dimensions, creating a positive cycle of wellbeing.
Health and wellbeing as a collective resource
At the national or collective level, when large populations experience optimal health and wellbeing, the benefits multiply across society. Healthy populations are more productive, which strengthens the economy. Reduced rates of illness decrease the burden on healthcare systems, freeing up resources for other priorities such as education and infrastructure.
For instance, when many individuals experience optimal mental health and wellbeing with low stress levels, they can contribute more effectively to their workplaces and communities. This collective productivity drives economic growth, which benefits the entire nation through increased employment opportunities, better services, and improved living standards.
Exam tips:
- Start by identifying a specific aspect of optimal health and wellbeing in your response.
- Make explicit connections between this aspect and concrete benefits for individuals or countries.
- Where possible, show how benefits in one area lead to additional benefits in other areas, demonstrating the cascading effects of good health.
- Use specific examples rather than general statements to strengthen your explanations.
Describing global benefits of optimal health and wellbeing
Whilst health and wellbeing benefit individuals and nations, the pursuit of optimal health and wellbeing also creates significant advantages on a global scale. Understanding this skill requires shifting your perspective from individual or national contexts to consider the collective impact across countries and populations worldwide.
Transitioning from individual to global perspectives
Although your response may begin by considering impacts on individuals, to demonstrate this skill effectively you must extend your thinking to global contexts. This means considering what happens when large numbers of people across multiple countries experience optimal health and wellbeing simultaneously.
Communicable diseases and global health
Consider the global benefits of reduced rates of communicable diseases as an example. When fewer people worldwide suffer from diseases like malaria, measles, or tuberculosis, several positive outcomes emerge at the global level.
Reduced disease rates mean fewer people experience severe symptoms and premature death from these conditions. With better physical health and wellbeing across populations, more people have the capacity to work productively and contribute meaningfully to their societies. This increased productivity enables communities to generate more resources, including food production and infrastructure development, which can meet the needs of their populations more effectively.
When communities can adequately provide for their citizens' basic needs, this reduces a significant source of conflict between countries. Competition for scarce resources often drives international tensions and disputes. As more people gain access to the resources they need for a decent standard of living, they become better able to lead lives they value, which promotes overall health and wellbeing globally.
This creates a positive cycle where improved health leads to better resource generation, which in turn supports further improvements in health and wellbeing.
Economic development and global prosperity
Optimal health and wellbeing can promote economic development on a global scale. When populations worldwide are healthy, they can participate more fully in education and employment. This creates a skilled, productive global workforce that drives innovation, trade, and economic growth across borders.
Economic development reduces poverty levels internationally, which improves access to healthcare, nutrition, and education for populations in low-income countries. This narrowing of global inequalities contributes to greater stability and cooperation between nations.
Other global benefits
Beyond economic development, optimal health and wellbeing contribute to:
- Reduced healthcare costs globally: When populations are healthier, the global burden of disease decreases, reducing the demand for expensive medical interventions and allowing resources to be directed toward prevention and health promotion.
- Enhanced global security: Healthier populations are less vulnerable to exploitation and conflict, contributing to greater political stability and peace worldwide.
- Environmental sustainability: Healthy populations are better able to implement and maintain sustainable practices, as they have the resources and capacity to consider long-term environmental protection rather than focusing solely on immediate survival needs.
- Social cohesion and cooperation: When people experience good health and wellbeing, they are more likely to engage in cooperative behaviours and support international efforts to address global challenges such as climate change, humanitarian crises, and disease outbreaks.
Exam tips:
- Always ensure your response addresses the global scale explicitly, not just individual or national impacts.
- Use connecting language that shows how individual benefits accumulate to create global change.
- Consider multiple global benefits where possible, not just economic outcomes.
- Think about how improved health in one region can positively affect other regions through reduced disease transmission, increased trade, or greater stability.
Identifying and explaining the WHO's prerequisites for health
The World Health Organization has identified nine prerequisites for health that must be present to support optimal health and wellbeing. Being able to recall these prerequisites and explain how they contribute to improved health outcomes is an essential skill.
The nine prerequisites for health
The World Health Organization identifies the following as essential prerequisites for health:
- Peace
- Shelter
- Education
- Food
- Income
- A stable ecosystem
- Sustainable resources
- Social justice
- Equity
Using memory aids
Remembering all nine prerequisites can be challenging, so using memory aids can be helpful. Here are two strategies:
Mnemonic sentence: "People should enjoy edible food including some sustainable stew"
This gives you the first letters: P-S-E-E-F-I-S-S-S
Acronym list: Peace / Shelter / Equity / Education / Food / Income / Social justice / Sustainable resources / Stable ecosystem
Whilst these memory aids help you recall the prerequisites during exams, you must still develop a thorough understanding of what each one means and how it promotes health and wellbeing.
Explaining links to improved health outcomes
Simply listing the prerequisites is insufficient. You need to demonstrate how each prerequisite contributes to better health and wellbeing outcomes. This requires understanding what each prerequisite involves and its potential impacts.
Example: Peace as a prerequisite
Worked Example: Peace and Health Outcomes
Peace means the absence of conflict and war within and between nations. When peace exists, infrastructure such as water treatment facilities, hospitals, roads, and schools is less likely to be destroyed or damaged. This preservation of infrastructure increases people's capacity to access essential resources.
For instance, intact water infrastructure ensures communities can access clean, safe water. Water is essential for maintaining hydration, which directly supports physical health and wellbeing by enabling proper bodily function, maintaining energy levels, and supporting overall physical capacity. Access to clean water also prevents waterborne diseases, further protecting physical health.
Beyond the direct health benefits, peace allows resources and energy to be directed toward health promotion and development rather than conflict and rebuilding. This creates environments where all dimensions of health and wellbeing can flourish.
Understanding other prerequisites
Each of the nine prerequisites connects to health outcomes in specific ways:
- Shelter provides protection from the elements, contributes to physical safety, and supports mental health through the security of having a stable place to live.
- Education enables people to make informed health choices, access better employment opportunities, and understand how to prevent disease and promote wellbeing.
- Food provides the nutrients necessary for physical growth and development, maintains energy levels, and supports immune function.
- Income enables access to healthcare, nutritious food, adequate housing, and other resources that promote health across all dimensions.
- A stable ecosystem ensures clean air and water, reduces exposure to environmental hazards, and provides resources needed for survival.
- Sustainable resources guarantee that future generations will have access to the necessities for health, promoting long-term wellbeing.
- Social justice ensures fair treatment and equal access to opportunities, which supports mental, emotional, and social health and wellbeing.
- Equity means everyone has fair opportunities to achieve optimal health regardless of their circumstances, reducing health inequalities.
Exam tips:
- Memorise the nine prerequisites using a method that works for you, but focus most of your study time on understanding what each one means.
- Practice explaining how different prerequisites link to various dimensions of health and wellbeing.
- When explaining a prerequisite's impact, follow this structure: identify the prerequisite, state what it means or what impact it has, then make a specific link to improved health and wellbeing.
- Be prepared to explain how any prerequisite can affect multiple dimensions of health and wellbeing, as they often have wide-ranging impacts.
