Defining Health & Wellbeing + Physical Factors
What Is Health and Wellbeing?
Many people think being “healthy” simply means not being ill. The Pearson BTEC specification uses a much broader definition. Health and wellbeing is a combination of physical health and social and emotional wellbeing — it is not just the absence of disease or illness. This means a person can be physically fit but still have poor wellbeing if they feel lonely, stressed, or unhappy.
Health and wellbeing is defined as a combination of physical health and social and emotional wellbeing, and not just the absence of disease or illness.
This definition matters because it shapes how health and social care professionals assess and support individuals. They do not just treat physical symptoms — they consider a person’s mental state, relationships, and overall quality of life. Throughout this unit, you will see factors that affect health and wellbeing grouped into physical, lifestyle, social, cultural, economic, and environmental categories.
Inherited Conditions
Some health conditions are passed from parents to children through inherited conditions. These are caused by faulty genes and are present from birth, though symptoms may not appear immediately. The specification requires you to know two key examples.
Sickle cell disease affects the red blood cells, which become crescent-shaped instead of round. This means they can block blood vessels and do not carry oxygen as effectively. Symptoms include episodes of severe pain (called crises), fatigue, and increased risk of infections. It affects physical wellbeing through pain and tiredness, emotional wellbeing through frustration and anxiety about crises, and social wellbeing because hospital stays and absences from school or work can lead to isolation.
Cystic fibrosis causes thick, sticky mucus to build up in the lungs and digestive system. This leads to frequent chest infections, difficulty breathing, and problems absorbing nutrients from food. Daily physiotherapy and medication are needed. The condition affects all areas of PIES development — physically through breathing difficulties, intellectually through missed education, emotionally through frustration at limitations, and socially through feeling different from peers.
Physical Ill Health
Physical ill health covers conditions that damage the body’s normal functions. The specification names three conditions you must know.
Cardiovascular disease (CVD) is a general term for conditions affecting the heart and blood vessels, including coronary heart disease, heart attacks, and strokes. Risk factors include high blood pressure, smoking, poor diet, and lack of exercise. CVD can limit a person’s physical abilities and create anxiety about future health events, reducing emotional wellbeing.
Obesity is when a person has an excessive amount of body fat, usually measured using BMI. A BMI of 30 or above is classified as obese. Obesity increases the risk of type 2 diabetes, CVD, joint problems, and some cancers. It can also affect emotional wellbeing through low self-esteem and social wellbeing through bullying or discrimination.
Type 2 diabetes occurs when the body does not produce enough insulin or the body’s cells do not react to insulin properly. This leads to high blood sugar levels. It is strongly linked to obesity, poor diet, and lack of physical activity. If unmanaged, it can cause serious complications including nerve damage, kidney problems, and vision loss.
CVD, obesity, and type 2 diabetes are closely linked — they share common risk factors such as poor diet, lack of physical activity, and smoking. Obesity significantly increases the risk of developing both CVD and type 2 diabetes.
Mental Ill Health
Mental ill health affects how a person thinks, feels, and behaves. The two conditions named in the specification are anxiety and stress.
Anxiety involves persistent feelings of worry, fear, or nervousness that are difficult to control. Physical symptoms can include a racing heart, sweating, and difficulty sleeping. Anxiety can prevent a person from socialising, attending work or school, and enjoying daily activities — affecting all areas of their PIES development.
Stress is the body’s reaction to feeling threatened or under pressure. Short-term stress can be helpful (motivating someone before an exam), but long-term stress damages health. Chronic stress can cause headaches, high blood pressure, digestive problems, weakened immunity, difficulty concentrating, irritability, and withdrawal from relationships.
Physical Abilities and Sensory Impairments
Physical abilities refer to what a person can physically do — walking, lifting, gripping, and so on. Conditions like arthritis, cerebral palsy, or injuries from accidents can reduce physical abilities. This can affect independence, employment opportunities, and self-esteem.
Sensory impairments affect the senses, most commonly sight and hearing. A person who is deaf or blind faces challenges in communication, accessing information, and navigating their environment. Sensory impairments can lead to social isolation if support is not available, and may affect emotional wellbeing through frustration or dependency on others.
Both physical abilities and sensory impairments highlight why the definition of health and wellbeing goes beyond “absence of disease” — a person may have a stable condition but still experience reduced wellbeing if they lack support, face discrimination, or feel excluded from social activities.
