Breathing in pollution may make you concerned about your lungs, but it’s not just about that anymore. Long-term exposure to air pollution can also harm your brain. Experts and doctors are now warning that constant exposure to pollutants, especially fine particulate matter (PM2.5) can quietly be increasing the risk for your brain of developing dementia and other cognitive disorders. These ultra-fine particles are notoriously known for penetrating deep into the lungs and eventually entering the bloodstream, making a way to the brain. Once this process has happened and the particles have begun on a journey, they cause a lot of harm and the worst part is that this harm may not even be visible till it’s too late. “Air pollutants such as PM2.5 can reach the brain and cause inflammation, oxidative stress, and damage to brain cells. This can lead to cognitive decline and impair memory, thinking, and daily functioning,” explains Dr. Sunil Kutty, a leading Neurosurgeon (Brain & Spine) at NewEra Hospital, Vashi, Navi Mumbai. Research and studies have also suggested that people living in areas with persistently high pollution levels are especially at greater risk of developing neurodegenerative conditions, including vascular Dementia and Alzheimer’s disease. The longer the exposure lasts for, the higher are the chances for permanent cognitive impairment. Prolonged inhalation of pollutants can also worsen any existing neurological conditions by cutting down oxygen supply and accelerating nerve cell damage in the brain. Dr. Kutty emphasizes that prevention is crucial. “Reducing exposure to air pollution is key to protecting the brain. So, make sure to stay healthy, wear a mask, in case you have to venture out when there is air pollution,” he adds. In addition to protective gear, he mentions that simple lifestyle steps like using air purifiers, avoiding outdoor activity during peak smog hours, maintaining a nutrient-rich diet, and staying physically active can support better brain health. As the air quality index continues to drop and become worse in Delhi NCR, these insights serve as a timely reminder that the damage air pollution causes can go far beyond just incessant coughing or watery eyes. It also silently holds the strength to alter how our brain functions, and often this comes without any early warning signs. Understanding this connection between the functioning of the brain and how it can be altered by air pollution could help drive stronger policies and encourage individuals that take everyday steps to safeguard their mental health.
