Boosting Community Wellness: The Vital Role of Environmental Health
Environmental health is crucial for community well-being, serving as a reminder of the significance of a healthy environment in promoting human health. As urban areas face severe air pollution challenges, it is essential to implement scientific and cross-sectoral strategies to minimize emissions and improve air quality through sustainable energy sources. This was emphasized by Alireza Raeisi, an official from the health ministry, during the observance of World Environmental Health Day on September 26.
During his address, Raeisi praised the dedication of environmental health professionals and expressed optimism about enhancing environmental health through the integration of modern technologies and the expertise available at universities of medical sciences. The theme for this year’s World Environmental Health Day, ‘Clean Air, Healthy People’, highlights the critical connection between air quality and public health.
On this day, the focus is on raising awareness and mobilizing action to mitigate air pollution’s effects, combat climate change, and tackle respiratory diseases. Air pollution has significant repercussions, leading to various health issues such as:
- Respiratory diseases
- Heart conditions
- Exacerbation of asthma
- Lung cancer
- Reduction in fertility rates
- Premature deaths
Everyone has a part to play in advocating for clean air policies. Sustainable practices can significantly lessen the impact of air pollution while enhancing the health and well-being of individuals and communities. According to the World Health Organization (WHO), a healthy environment can avert approximately 25% of the global disease burden.
The current environmental crisis has profound implications for health as climate change escalates, biodiversity declines, and pollution proliferates. Poor environmental conditions impact health both directly and indirectly, influencing food production, migration, economic stability, and social inequalities. Therefore, urgent action is necessary to transform our lifestyle, work, production, and governance.
Strengthening primary prevention is vital, given its potential to significantly reduce the disease burden and healthcare expenses. Effective cross-sectoral collaboration is essential in addressing the environmental determinants of health, which span across:
- Health
- Energy
- Industry
- Agriculture
- Transport
Integrating actions across these sectors often results in significant co-benefits and cost reductions. The sources of fine particulate emissions include various combustion activities, such as:
- Motor vehicles
- Power plants
- Wood burning
- Specific industrial processes
These particles can be emitted directly or formed as secondary pollutants in the atmosphere. Generally, the primary sources of particulate matter emissions stem from:
- Fuel combustion (coal and wood burning)
- Diesel engines
- Industrial processes
- Agricultural activities
- Vehicle emissions
Suspended particles tend to affect air quality, particularly during colder months. Numerous studies have established a correlation between exposure to these particles and various health complications, including:
- Premature death in individuals with heart and lung diseases
- Non-fatal heart attacks
- Irregular heartbeats
- Exacerbation of asthma
- Decreased lung function
- Increased respiratory symptoms
- Reduction in life expectancy
A report from the Health Ministry indicates that air pollution in Iran is responsible for approximately 50,000 deaths annually, with 7,000 fatalities occurring in Tehran alone. Additionally, Isfahan and Arak experience 2,029 and 661 deaths attributed to air pollution, respectively. The financial burden on the health system due to air pollution in Isfahan reaches around $796 million, while in Arak, it amounts to about $2.564 million.
To effectively combat air pollution, it is imperative to implement stringent environmental regulations, enforce robust laws, and promote the development of renewable energy sources. Raising public awareness about the detrimental effects of pollution and providing education on how to address it is equally important. Other effective measures include:
- Improving waste management systems
- Enhancing sewage and water treatment facilities
- Boosting public health services in underserved areas
Consequently, policies aimed at reducing air pollution present a dual benefit for both public health and climate change mitigation. They not only lessen the disease burden linked to air pollution but also contribute to both immediate and long-term climate change solutions.
