Haze is a form of air pollution. Burning plant and vegetation matter releases airborne particle, which can travel to other areas blown by prevailing wind. These airborne particles have complex components are structures, and varying sizes.
The smaller particles (PM10 and below) when inhaled, are deposited onto the airways and lungs tissue. Being foreign irritants, these particles can set up inflammatory and harmful reaction, and such inflammatory reactions have been proven in scientific studies. Patients with underlying lung or airways disease (such as asthma and COPD) are more at risk of flare up of their disease when exposed to these particulate matters.
What to do to avoid respiratory problems relating to the haze?
Therefore, patients with chronic respiratory illness should stay indoors and avoid outdoors exercise during high alert haze levels. For asthmatic patients, regular use anti-asthma drugs (controllers) will stabilize underlying asthma, so that even when exposed to particulate matters, major flare up of symptoms can be prevented.
