Impact of Haze and how to protect your respiratory health
As haze episodes become increasingly frequent in Southeast Asia, safeguarding your respiratory health has never been more important. Prolonged exposure to haze can irritate your airways, exacerbate chronic conditions like asthma or chronic obstructive pulmonary disease (COPD), and reduce overall lung function. Understanding the risks and taking proactive steps is essential to protect yourself and your loved ones.
How haze affects your respiratory system
Haze contains fine particulate matter (PM2.5) and pollutants that can penetrate deep into your lungs. Common effects include:
- Irritated airways leading to coughing, wheezing, and shortness of breath
- Exacerbation of chronic conditions such as asthma or chronic obstructive pulmonary disease (COPD)
- Increased susceptibility to infections, as lung defences may be weakened
Vulnerable groups, including children, the elderly, and individuals with pre-existing respiratory or heart conditions, are at greater risk.
Steps to protect yourself
Monitor air quality: Use local apps or government advisories to track the Pollutant Standards Index (PSI).
Stay indoors during peak haze: Keep windows and doors closed. Use air purifiers if possible.
Use masks wisely: N95 or equivalent respirators can filter out harmful particulate matter.
Maintain hydration and lung health: Drink plenty of water and avoid outdoor exertion.
Seek professional advice: Consult a healthcare provider if you experience persistent cough, breathlessness, or chest discomfort.
