Introduction
Haze season is a recurring environmental issue in Malaysia, often caused by forest fires and transboundary pollution. During this period, air quality drops significantly, posing serious health risks—especially for people with asthma.
If you or your loved ones have asthma, understanding how haze affects your lungs and knowing how to protect yourself is crucial.
What Is Haze and Why Is It Dangerous?
Haze is a form of air pollution filled with fine particles known as PM2.5. These particles are small enough to enter your lungs and bloodstream, causing irritation and worsening respiratory conditions.
In Malaysia, haze levels are measured using the Air Pollutant Index (API):
0–50 (Good): Safe
51–100 (Moderate): Acceptable
101–200 (Unhealthy): Risk for sensitive groups
200+: Very unhealthy to hazardous
How Haze Triggers Asthma
People with asthma are highly sensitive to polluted air. Haze can:
Irritate airways and cause inflammation
Trigger asthma attacks
Increase coughing, wheezing, and breathlessness
Reduce lung function over time
Even short exposure can worsen symptoms, especially in children and the elderly.
Common Symptoms to Watch For
During haze season, asthma symptoms may become more frequent or severe:
Shortness of breath
Chest tightness
Persistent coughing
Wheezing
Fatigue due to poor oxygen intake
If symptoms suddenly worsen, seek medical help immediately.
How to Protect Yourself During Haze Season
1. Check Air Quality Daily
Monitor the API using apps or official websites. Avoid outdoor activities when levels exceed 100.
2. Wear a Proper Mask
Use N95 masks when going outside. Regular surgical masks do not effectively filter fine particles.
3. Stay Indoors as Much as Possible
Keep windows and doors closed during high pollution days. Limit outdoor exercise or activities.
4. Use an Air Purifier
A HEPA air purifier can significantly improve indoor air quality and reduce exposure to harmful particles.
5. Always Carry Your Inhaler
Ensure your reliever inhaler is accessible at all times. Follow your doctor’s asthma action plan.
6. Keep Yourself Hydrated
Drinking enough water helps keep your airways moist and reduces irritation.
7. Avoid Additional Irritants
Stay away from smoke, dust, strong perfumes, and other triggers that can worsen asthma symptoms.
Special Care for Children and Elderly
Children and older adults are more vulnerable during haze season. Parents should:
Limit children’s outdoor play
Ensure proper mask usage
Watch for early asthma symptoms
Elderly individuals should also minimize exposure and seek early treatment if symptoms arise.
When Should You See a Doctor?
Seek medical attention if you experience:
Frequent asthma attacks
No relief from inhaler use
Severe breathlessness
Difficulty speaking due to breathing
Early treatment can prevent serious complications.
Long-Term Prevention Tips
Follow your prescribed asthma treatment plan
Schedule regular check-ups
Improve indoor air quality year-round
Stay updated on haze forecasts
Conclusion
Haze is more than just an environmental nuisance—it’s a serious health concern, especially for asthma sufferers. By taking preventive measures and staying informed, you can protect yourself and your family during Malaysia’s haze season.
