Key Insights

• 🌬️ Air pollution is responsible for seven million premature deaths each year, equivalent to the entire population of Madrid. However, despite widespread scientific knowledge and media coverage, there is a lack of urgent action being taken to address this issue.
• 👃 Air pollution is a complex mixture of solid particles, liquid droplets, and chemicals that come from various sources such as household burning, industry, and traffic. These toxic pollutants are constantly inhaled into our lungs, causing harm to our organs.
• 🤔 Air pollution not only affects our lungs but also has a direct impact on our brain. Research shows that air pollutants can cross into the bloodstream and reach the brain, potentially leading to negative effects on neural development, cognitive function, and increased risks of diseases like Alzheimer's and Parkinson's.
• 👶 Prenatal and early childhood exposure to air pollution can have long-term negative effects on neural development, cognitive outcomes, and behavior disorders like autism and ADHD.
• 👵 Long-term exposure to particulate matter can cause cognitive decline and accelerate brain aging in adults. It is even linked to increased risks of dementia.
• 🌍 Air pollution affects everyone, regardless of location or income level. It is a global problem that requires strong commitments and actions from individuals, civil society, the private sector, and policymakers. ⏳ Delaying action on air pollution can have severe consequences for human health. Politicians must be aware of the risks and take swift action such as reducing traffic, investing in renewable energy, and promoting cleaner transport and cooking methods.
• 💪 Each individual has a role to play in reducing air pollution by changing consumption habits, commuting methods, and energy use. Strong political commitments and will are essential to combat this invisible killer and protect our brain power.
