Detailed answer

Exposure to air pollution, especially fine particulate matter (PM2.5), has been linked to various adverse effects on brain health. Fine particles can enter the bloodstream through inhalation and reach the brain, triggering inflammation and oxidative stress. These elevated levels of inflammation and oxidative stress can lead to neurodegenerative diseases, cognitive decline, and an increased risk of stroke. Additionally, air pollution can also contribute to the development and progression of psychiatric disorders such as depression and anxiety. It is crucial to reduce exposure to air pollution to protect brain health and overall well-being.
