How to protect your lungs from air pollution?

Air pollution has always been a major concern across the world. With increasing traffic, construction, and industrial activities, the air we breathe is getting more polluted every day. Although we may not always see it, tiny harmful particles are constantly floating around us — entering our lungs with every breath we take. Over time, this can lead to serious lung problems. If you're experiencing breathing issues or prolonged coughing, you can consult our Pulmonologist in Jaipur at CK Birla Hospitals for expert evaluation and care.

How does air pollution affect the lungs?

When we breathe, we take in more than just oxygen. The air around us can also carry harmful substances like smoke, dust, chemicals, and tiny particles (called PM2.5 and PM10). These are often too small to see, but they go deep into our lungs when we inhale.

• Irritation in Airways: Pollutants can cause dryness and irritation in your nose, throat, and lungs. You may feel a burning sensation or start coughing.
• Breathing Difficulty: It becomes harder to breathe, especially for people with asthma, COPD, or other lung conditions.
• Lung Infections: Weakened lungs are more likely to get infections such as bronchitis or pneumonia.
• Long-Term Lung Damage: Continuous exposure may reduce lung function and cause diseases like COPD or lung cancer.
• Triggering Existing Conditions: People with asthma, heart problems, or allergies may see their symptoms get worse on poor air quality days.

Who is most at risk from air pollution?

Some people are more sensitive to polluted air and may fall sick faster:

• Children – Their lungs are still growing and are more sensitive.
• Older adults – Lung function reduces with age.
• People with asthma or COPD – Pollution can trigger attacks.
• Pregnant women – Pollution can harm both mother and baby.
• Outdoor workers – Like traffic police, delivery agents, or labourers.

Even healthy people may feel tired, get coughs, or feel breathless on bad air quality days.

Warning signs of lung damage from pollution

Many people ignore early signs of lung problems. But early action can save your health. Watch for these warning signs:

• Regular coughing or wheezing
• Shortness of breath, even while walking
• Chest tightness or pain
• Tiredness without reason
• Frequent colds or throat infections
• Voice becoming hoarse

If these symptoms don’t go away, it’s time to check your lungs.

Harmful pollutants that directly impact your heart

Air pollution doesn't just harm the lungs — it also affects your heart. Below are some common pollutants found in Indian cities:

How to check your lung health?

If you're facing breathing problems, take a lung health test. Here are some options:

• Spirometry: A test to check how much air you can inhale and exhale.
• Chest X-ray or CT scan: Helps detect damage or disease in the lungs.
• Pulse oximeter: Measures oxygen levels in your blood.
• Consult a Doctor: Especially if you live in a polluted area or show symptoms.

Ask your doctor how to check your lung health regularly if you're at risk.

Ways to protect your lungs from polluted air

You can’t avoid air pollution completely, but you can reduce your exposure. Here’s how:

1. Check Air Quality Daily: Use apps like SAFAR or AQI India. If the AQI is over 200, avoid going out.
2. Wear an N95 Mask: It filters out most harmful particles.
3. Avoid Busy Roads: Walk on quieter streets, especially in the morning when pollution is higher.
4. Keep Car Windows Closed: Prevent outdoor pollutants from entering.
5. Avoid Burning Trash or Wood: Burning releases toxic gases. Use safer waste disposal and cooking methods.

Tips to Improve Indoor Air Quality

Indoor air can be just as harmful. Follow these tips for a cleaner home:

• Ventilate in the Afternoon: Let fresh air in when pollution levels are lower.
• Use Exhaust Fans: Especially in the kitchen and bathroom to remove fumes.
• Clean Regularly: Mop floors and wipe surfaces with a wet cloth to reduce dust.
• Avoid Chemical Sprays: Limit use of air fresheners, incense, and mosquito sprays.
• Use Air-Purifying Plants: Areca palm, aloe vera, and snake plant are good options.
• Use an Air Purifier: Especially helpful in cities like Delhi and Kolkata.

How to improve lung health naturally?
