Healthy air is something we rarely think about until we can see the air around us change.
As haze affects parts of Malaysia, it is worth remembering that air quality is not only an environmental issue. It is a health issue.
And the concern is not simply “less oxygen.”
Haze contains a mixture of airborne pollutants, including fine particulate matter such as PM2.5 particles small enough to travel deep into the lungs and, in some cases, enter the bloodstream.
That matters because the lungs are not isolated from the rest of the body.
The air we breathe interacts continuously with our respiratory and cardiovascular systems. When pollutant exposure increases, the body may experience greater irritation, inflammation and physiological stress.
During periods of poor air quality:
• Check your local API before planning outdoor activities.
• Reduce strenuous outdoor exercise when air quality is unhealthy.
• Keep windows and doors closed when outdoor air quality is poor.
• Use appropriate air filtration indoors where possible.
• If you need to spend time outdoors in haze, a properly fitted particulate respirator such as an N95 can help reduce exposure to fine particles.
• Pay particular attention to children, older adults, pregnant women, and people with heart or respiratory conditions.
And remember: clean air is not simply air with “more oxygen.”
Healthy air is air with fewer harmful pollutants allowing the respiratory and cardiovascular systems to do their jobs without unnecessary environmental stress.
We often talk about nutrition, movement, sleep and recovery as foundations of long-term health.
The quality of the air we breathe belongs in that conversation too.
Take care of yourself, and check the air before you step outside.
