Airborne Threats: Discover the link between Air Pollution and Mental Health

Have you ever been caught in a traffic jam when suddenly your eyes begin to burn and itch? It must have happened to most of you, making the invisible air pollution feel all too real. The dark smog that covers the entire civilisation takes a toll on physical, social and even mental well-being. It is a slow and silent killer that leaves no trace. It's concerning how the air we breathe, a fundamental necessity for life, has become increasingly polluted and harmful. It’s quite possible that your thoughts and mood are in sync with the quality of air you breathe in. Let's delve into how air pollution affects your mental health.

The air we breathe

Let us understand the concept of air pollution by analysing a day’s routine. Imagine a time before the advent of large-scale factories and mass production, when the air was pure and the skies were clear. Now, consider the bustling cities of today, where smog often obscures the sun and the air can be laden with harmful pollutants. This historical perspective highlights the significant environmental changes brought about by the rise of modern industry and their potential impact on human health. However, there's more to the air than meets the eye. Beyond the visible sights and sounds of city life, a complex mixture of substances exists in the atmosphere. This includes particles, gases, and other pollutants released from various sources, such as vehicle exhaust, industrial emissions, and even construction activities.

Some of these are- particulate matter, sulphur dioxide, carbon monoxide, nitrogen dioxide, and ozone. Now, let us understand how air pollution affects human health.

Air pollution and mental health: The connecting link

Throughout the day, we are continuously exposed to the pollutants present in the air we breathe. Now, let’s dive into science and decode how air pollution affects mental health. When inhaled, these pollutants can enter the bloodstream and reach the brain. Studies suggest that they can trigger inflammation in the brain, which can disrupt the normal communication between neurons. This disruption may be associated with mental health issues such as anxiety, depression, restlessness, and mood swings (including bipolar disorder), although current research shows strong links rather than definitive evidence that air pollution directly causes these conditions.

However, the most devastating effect is on children, with developing brains and bodies. Long-term exposure of children to air pollutants such as particulate matter can manifest as memory and attention issues. Some researchers also claim effects of air pollution on children's mental well-being are serious enough to send them to emergency psychiatry departments.

How air pollution affects the brain biologically

Air pollution can have significant biological effects on the brain. Tiny particulate matter and harmful chemicals from polluted air can enter the bloodstream through the lungs and cross the blood–brain barrier, leading to inflammation and oxidative stress in brain tissues. This can damage neurons, impair cognitive functions, and increase the risk of neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Chronic exposure to air pollutants has also been linked to mood disorders, memory problems, and reduced attention span, highlighting the profound impact environmental toxins can have on neurological health.

Small steps towards better mental health

Both air pollution and mental health are global concerns. It directly affects each inhabitant of our planet Earth. Isn’t it a duty to put in small efforts that could make this invisible envelope of polluted air a little cleaner? Here are a few suggestions that you can adapt to your daily living for cleaner air-

• Try walking instead of taking a cab or using a personal vehicle for short distances.
• Remember to switch off your car engine while halting for minutes or in traffic. A stationary engine is a pollution hotspot.
• Avoid burning your trash. It emits dangerous gases like carbon monoxide which is known to induce irritation, impulsiveness, anxiety and even depression.
• Indoor pollutants, such as dust, and chemicals, can also significantly impact health. Therefore, consider conserving energy at home by switching to efficient appliances and heating systems.
• Support local initiatives for tree planting and urban greening. Consider volunteering your time to help maintain existing green spaces or advocate for policies that promote urban forestry.

Key takeaways

Air pollution is a real threat. It not only plays with your lungs but also affects your mental well-being. Breathing polluted air for a long time can make you feel anxious and depressed can lead to more serious mental disorders. The risk is greater for kids, the elderly and those already suffering from mental health issues. But as dangerous as it seems, taking little steps towards a green, clean and safe environment can keep you physically and mentally fit. Understanding how air pollution affects mental health and how air pollution affects human health is crucial in our collective effort to create a healthier world.
