What’s in Dhaka’s Air?

How Does Air Pollution Affect Your Health?

Breathing polluted air in Dhaka isn’t just unpleasant; it’s dangerous. The harmful particles and gases in the air can damage your lungs, heart, and immune system. Children are especially at risk. Let’s break down how air pollution harms your body and why it’s important to protect yourself.

• Lung Problems: Polluted air irritates your lungs, making it harder to breathe. You may experience coughing, wheezing, or chest tightness. Over time, this can lead to serious conditions like asthma, chronic bronchitis, or even lung cancer. The tiny particles in the air settle deep in your lungs, causing long-term damage.
• Heart Issues: The tiny particles in polluted air don’t just stay in your lungs. They can enter your bloodstream, increasing the risk of heart attacks and strokes. These particles can also raise blood pressure, putting extra strain on your heart. Over time, this can lead to life-threatening heart conditions.
• Weaker Immune System: Air pollution weakens your body’s natural defenses. This makes it harder for your immune system to fight off infections. You may find yourself getting sick more often or taking longer to recover from illnesses.
• Harm to Children: Children are more vulnerable to air pollution. Dirty air can slow their lung growth and harm their brain development. It can also affect their ability to learn and concentrate. Kids who grow up breathing polluted air are more likely to develop asthma and other health problems.
• Other Health Problems: Air pollution doesn’t just affect your body; it can also harm your mind. Many people experience headaches, fatigue, and even mental health issues like depression. Long-term exposure to polluted air can make you feel constantly tired and unwell, affecting your overall quality of life.

Protecting yourself from air pollution is vital. By understanding its effects, you can take steps to reduce your exposure and safeguard your health. Simple actions like wearing masks, staying indoors on high-pollution days, and using air purifiers can make a big difference.

What Can You Do to Protect Yourself?

Living in Dhaka’s polluted air can feel overwhelming, but you’re not powerless. While you can’t control the air outside, you can take steps to protect yourself and your family. Small changes in your daily habits can make a big difference in reducing your exposure to harmful pollutants. Let’s explore practical ways to stay safe and breathe cleaner air.

Stay indoors during peak pollution. Avoid going outside during rush hours or when the air quality is poor. Check air quality updates and plan your activities for cleaner times of the day. Staying indoors during high-pollution periods can significantly reduce your exposure.

Use masks. When you need to go out, wear a good-quality mask like an N95. These masks filter out harmful particles and protect your lungs. Make sure your mask fits well for the best protection.

Keep your home clean. Use air purifiers to improve indoor air quality. Keep windows closed on high-pollution days to prevent dirty air from entering. Regularly clean surfaces to remove dust and pollutants that settle indoors.

Plant trees. If you have space, plant trees around your home. Trees act as natural air filters, absorbing pollutants and releasing oxygen. Even small plants can make a difference in improving the air around you.

Support clean energy. Reduce your use of fossil fuels. Walk, cycle, or use public transport whenever possible. Switching to cleaner energy options helps lower pollution levels and benefits everyone.

Raise awareness. Talk to your friends, family, and community about air pollution. Encourage them to take action and adopt cleaner habits. Together, small efforts can lead to big changes.

Protecting yourself from air pollution is not just about your health—it’s about creating a better environment for everyone. By making these small but meaningful changes, you can reduce your exposure and inspire others to do the same. Every step you take brings us closer to cleaner air and healthier lives.

What Can the Government Do?

While your actions matter, the government has the power to create lasting change. By enforcing stricter rules and promoting cleaner practices, it can significantly reduce air pollution in Dhaka. Let’s look at how government efforts can make the air safer for everyone.

• Enforce stricter vehicle emission standards to reduce harmful gases.
