  1. The Urban Environment Impacts on Health and Wellbeing A successful urban area stimulates those who live and work there and reinforces self-esteem. The urban environment affect health and wellbeing of everyone who lives and works there. Many problems are concentrated in the most deprived areas where environmental, social and economic factors interact especially children and older people. Relationship between health, wellbeing and place are complex interacting and poorly understood.

  2. Effects of Urban Environment on Health • Air pollution: 24,000 deaths/yr brought forward by~8 months and 24,000 hospital admissions. • Traffic accidents: 3,300 deaths and 29,000 serious injuries/yr. • Climate: Winter - 25,700 extra deaths Dec 2005-March 2006. Summer - 2,000 excess deaths in heat-wave of 2003. • Mental health: Strong association between urban residence and psychiatric disorders. • Infectious disease: Spread of pandemic flue and new diseases with climate change. • Obesity: 34,000 extra deaths each year.

  4. AIR POLLUTION PARTICLES AND THE LUNG • 1,000,000,000,000 particles enter into lungs daily • 10,000 lts of air pass through the lungs every 24 hours. • Surface area exposed to the external environment - 150 m2
