Lifestyle Choices & Life Events
Lifestyle Choices: The Decisions We Make
Unlike life factors (circumstances beyond an individual’s control), lifestyle choices are behaviours a person actively selects. They include what a person eats, how active they are, whether they smoke, and how they use alcohol or drugs. These choices do not occur in a vacuum — they are strongly influenced by life factors (poverty limits food choices), life events (bereavement can trigger drinking), and the behaviours of those around us (peer pressure, role models, social media).
Diet
A balanced diet supports physical health, brain function, emotional stability, and the energy needed to participate in social life. The spec recognises that diet is not simply “healthy or unhealthy” — it also acknowledges vegetarian and vegan diets, which when well-planned can support good health, but which require careful planning to avoid deficiencies in nutrients such as vitamin B12, iron, and calcium.
An unbalanced diet can take two forms: malnutrition (inadequate nutrients — weakening immunity, slowing growth, reducing concentration) and over-nutrition (excess calories or saturated fat — increasing risk of obesity, cardiovascular disease, and Type 2 diabetes). Both forms affect PIES in interconnected ways: poor nutrition impairs brain function (I), reduces energy for socialising (S), damages self-image (E), and harms the body (P).
Physical Activity
The spec identifies three types of physical activity that contribute to health:
Aerobic activity raises the heart rate and improves cardiovascular fitness — walking, cycling, swimming, dancing. Builds heart and lung efficiency, reduces the risk of cardiovascular disease, and releases endorphins that improve mood. Muscle-strengthening activity maintains or builds muscle mass and bone strength — lifting weights, resistance exercises, yoga. Particularly important in adulthood and later adulthood to counter the natural decline in muscle mass. Bone-strengthening activity places stress on bones to increase density — running, skipping, jumping. Reduces osteoporosis risk, especially relevant for women approaching the menopause.
Physical activity supports all four PIES domains. Physically, it maintains a healthy weight and reduces chronic disease risk. Intellectually, exercise increases blood flow to the brain, supporting concentration and memory. Emotionally, it improves mood and self-esteem. Socially, activities such as team sports, leisure classes, and community volunteering provide opportunities to meet people and build relationships. The spec also emphasises activities that support mental well-being beyond structured exercise — leisure, socialising, hobbies, and voluntary work all count as lifestyle choices that benefit PIES.
The spec names three types of physical activity: aerobic (heart and lung fitness), muscle-strengthening (maintains muscle mass and bone strength), and bone-strengthening (increases bone density, reduces osteoporosis risk). Exam questions that ask you to ‘identify a type of physical activity’ expect one of these three categories.
Influence of Others
Lifestyle choices are shaped by role models — family members, peers, celebrities, and social media influencers. Peer pressure can push individuals toward risk-taking behaviour (drug use, binge drinking) or toward positive choices (joining a sports club, following a healthy diet). Social media can promote idealised body images, creating emotional pressures around appearance — particularly affecting adolescents’ self-esteem and dieting behaviour. Work-home life balance, community involvement, and voluntary activities are also lifestyle choices with significant PIES effects.
Smoking and Alcohol
Smoking remains one of the UK’s biggest preventable causes of death. Cigarettes contain nicotine (creating addiction), tar (damaging lung tissue), and carbon monoxide (reducing oxygen-carrying capacity of the blood). Smoking increases the risk of lung cancer, chronic obstructive pulmonary disease (COPD), cardiovascular disease, and stroke. Emotionally, while smokers often believe smoking reduces stress, the addiction cycle means anxiety increases between cigarettes. Socially, smoking bans in public places and social stigma have shifted smoking from a shared social activity to an increasingly marginalised one.
The spec makes an important distinction for alcohol: binge drinking (consuming a large quantity in a single session — defined as 8+ units for men or 6+ units for women in one session), alcohol abuse (regularly drinking to excess in a way that harms health), and dependence (addiction, where the body requires alcohol to function and withdrawal causes physical symptoms). Excessive alcohol damages the liver (cirrhosis), brain, and cardiovascular system. It impairs judgement and coordination, and chronic dependence devastates social relationships, employment, and financial stability.
The spec distinguishes between illegal drug misuse (e.g. cannabis, heroin, cocaine) and legal drug misuse (e.g. misuse of prescription medication, over-the-counter medicines, or substances such as solvents). Cannabis use is linked to anxiety, paranoia, and psychosis in regular long-term users. Heroin (an opiate) is highly addictive, carries fatal overdose risk, and destroys social functioning. Legal drug misuse — such as misuse of painkillers or sleeping tablets prescribed for one person but taken by another — is less visible but significant. All forms of drug misuse affect every PIES domain.
Life Events: Expected and Unexpected
Life events are different from both life factors and lifestyle choices — they are significant moments that punctuate the lifespan, often requiring major adjustment. The spec lists named examples under two categories.
Expected life events are those most people can anticipate at some point: starting school, leaving home, getting married, becoming a parent, starting employment, the birth of a sibling, moving house, entering further or higher education, and retirement. These bring positive change for many people but still require adaptation and can cause stress even when planned for.
Unexpected life events are sudden and unplanned: redundancy, divorce, bereavement, becoming a young carer, and a significant change in physical or mental health. Because they are unanticipated, individuals have less time to prepare coping strategies. Bereavement, for example, affects PIES in profound and lasting ways: physical health (disrupted sleep, appetite, immune function), intellectual functioning (concentration and memory impaired by grief), emotional wellbeing (grief, guilt, depression), and social participation (withdrawal from activities and relationships).
Expected life events include: starting school, leaving home, marriage, parenthood, retirement. Unexpected life events include: redundancy, divorce, bereavement, becoming a young carer, a significant change in health. Both types require adjustment and both can affect all four PIES domains.
How Life Factors, Lifestyle Choices, and Life Events Interrelate
The spec’s highest-tariff content is the requirement to show how these three elements interact to shape PIES outcomes. They rarely act in isolation. Consider this chain: a child raised in poverty (life factor) has limited access to fresh food (lifestyle choice constrained by economic factor) and lives in a damp, overcrowded home (living environment factor). As a teenager, they experience parental redundancy (unexpected life event), which creates financial stress and emotional instability at home. This increases the likelihood that the adolescent turns to smoking or alcohol (lifestyle choice) as a coping mechanism, further damaging physical health. Each element reinforces the others — and the PIES impact compounds across domains and across the lifespan.
Practitioners in care settings use this understanding when carrying out holistic assessments. A community nurse visiting a 60-year-old recently made redundant (life event) who has started drinking heavily (lifestyle choice) and is living in poor housing (life factor) will not treat each element in isolation — they will plan support that addresses the interconnected whole.
