Yes, haze can cause a cough.
Understanding Haze and its Effects on Respiratory Health
Haze, a result of air pollution, contains various particles and pollutants that irritate the respiratory system. These airborne irritants can trigger a cough as a protective reflex to clear the airways. The severity of the cough depends on factors like the concentration of pollutants in the haze, the duration of exposure, and an individual's pre-existing respiratory health conditions.
Specific Irritants in Haze that Contribute to Coughs
Haze is a complex mixture, but key components that trigger coughing include:
- Particulate Matter (PM): Tiny particles, especially PM2.5 (particles smaller than 2.5 micrometers), can penetrate deep into the lungs, causing inflammation and irritation, leading to a cough.
- Ozone (O3): A harmful gas, ozone irritates the lungs and airways, contributing to coughing and other respiratory problems.
- Other Pollutants: Sulfur dioxide, nitrogen dioxide, and other pollutants found in haze can further exacerbate respiratory irritation and coughing.
Who is Most Vulnerable?
Individuals with pre-existing respiratory conditions, such as asthma or chronic obstructive pulmonary disease (COPD), are particularly vulnerable to the effects of haze and are more likely to experience severe coughing and other respiratory symptoms. Children and older adults also have a higher risk of experiencing coughing due to haze exposure.
Practical Implications and Solutions
- Air Quality Monitoring: Staying informed about air quality indices (AQI) can help individuals take precautions when haze levels are high.
- Protective Measures: Wearing an N95 mask can help reduce the inhalation of harmful particles during periods of heavy haze.
- Reduce Exposure: Limiting outdoor activities during periods of high haze is crucial for protecting respiratory health.
Reference: Haze particles can give rise to acute symptoms such as cough, wheezing, shortness of breath and a feeling of tiredness and weakness. The effect of haze is aggravated in people with pre-existing heart or lung disorders.
