• To explore some of the key physical environmental influences on health
• To critique some of the key physical environmental factors influencing health drawing on current research and debate
• To understand the extent the physical environment in which we experience our live influences our health

• Agriculture and food production,
• Water and sanitation,
• Housing,
• The working environment,
• Employment,
• Education,
• Healthcare services
(*Note that this is not an exhaustive list)

Proposes that health can be improved by addressing four different factors:
1. individual lifestyles,
2. health services,
3. human biology/genetics
4. environmental influences.

• Type 1 – Explanations to do with individual behaviour
• Type 2 – Explanations to do with individual attributes and circumstances
• Type 3 – Explanations to do with the material environment and allocation of resources
• Type 4 – Explanations to do with social relationships and human subjectivity

According to Busfield’s typology:
• Our material environment and the way that resources are allocated and distributed have a significant impact on health.
• These factors are influenced by the way that society is organised politically and economically (Busfield, 2000).

• Over/under-consumption
• Availability of food
• Types of food
• Production processes
• Manufacturing
• Distribution
• Politics and economics

• Access to clean water & adequate sanitation is key to good health
• ‘Water problems’
- contamination,
- deficits and shortages,
- safety
- distribution
- links to agriculture & food production

• Housing and health are linked
• Issues:
– Overcrowding
– Damp and cold
– Poor quality
– Homelessness/temporary accommodation (link to poorer mental health)
– Growth of urban slums (migration into cities)

Three ways in which the working environment can impact on health:
• Working patterns
• Physical working environment
• Psycho-social impact

• Irregular shift patterns are detrimental to health (physical and mental)
Why?
- Disruption to sleep patterns
- Patterns of unhealthy behaviour associated with working shifts
- Stress
(Scott, 2000; Knutsson, 2003)

• ‘Sick Building Syndrome’ (symptoms caused by the condition of the building worked in)
• Impacts on health - reduces productivity and increases absenteeism (Epstein, 2008)
• Whitehall Studies – low levels of work demand, control and support associated with higher rates of absence (North et al, 1996)
• Impact of temporary and permanent employment – latter is better for health
(Aronsson et al, 2002)

• Being unemployed is detrimental to health (Lin et al, 1995)
• Causal link between unemployment and adverse health outcomes (many factors might contribute to this)
• Stewart (2001) – people who are unemployed experience higher death rates than people who are employed.
• Unemployment causes increased financial pressure and increases individual vulnerability to other life events (Kessler et al, 2009)

• There is a positive association between education and health (higher levels of education lead to better health experience)
• Ross and Wu (1995) offer 3 explanations for this:
– Work and economic conditions
– Social-psychological resources
– Lifestyle

The more educated you are, the more likely you are to:
- work full time in fulfilling, subjectively rewarding work
- report a sense of control over your life and your health and greater levels of social support
- reject health-damaging practices such as smoking and take up health enhancing practices

• The availability and accessibility of healthcare has a huge impact on health.
• For example, maternal and infant health varies considerably according to the income of a country.
• In the UK – ‘Post Code Lottery’ (label used to describe relative differences in the provision of healthcare related to geographic location)

• The physical environment (our living and working conditions) has a large part to play in our experiences of health (Donaldson and
Scally 2009),
• There are many other factors of our living and working conditions which impact on health.
• Different environmental factors may interact with each other to influence health (Green and Tones, 2010),

• natural and manmade disasters,
• climate change (Macdonald, 2006),
• out-door air pollution (Donaldson and Scally,
2009),
• solid waste disposal (Leonardi et al, 2005)
• transport

• It is important to consider factors within the physical environment and how these can influence health and health experience.
• Identifying environmental factors affecting health can help to address them and potentially make a real difference to health outcomes
• This can also influence health policy, how fiscal decisions are made and resource-allocation to improve health

• There are many aspects of the physical environment which impact on health and health experience throughout life through our living and working conditions.
• Research into these factors, and the impact of them, is challenging because whilst positive relationships and associations can be demonstrated, the causal mechanisms
(how and why) can be harder to determine.
• The relationship between our living and working conditions and the way that we live our lives is very complex and involves the interaction of a large number of different factors which are hard to separate from each other.
