The Medicine We All Share

As physicians, we spend much of our professional lives controlling risk factors one patient at a time.

Stop smoking. Control blood pressure. Lower cholesterol. Exercise. Eat better. Take your medicines.

But there is one cardiovascular and respiratory risk factor no individual can completely control: the air outside the door.

The present haze episode makes that uncomfortable truth visible. Smoke apparently transported from fires in Kalimantan has coincided with severely degraded PM2.5 readings across Metro Manila, reminding us that environmental health knows no national boundary.

Families should take today’s practical precautions seriously—limit exposure, protect vulnerable members, exercise indoors when necessary, keep indoor air cleaner and use properly fitting high-filtration respirators when unavoidable exposure warrants them.

But once the skies clear, we should not simply forget. The Philippines must confront its own everyday air pollution as seriously as it confronts foreign haze. Clean air should not depend on income, postcode or whether a family can afford an expensive air purifier.

It is something every child, commuter, street vendor, athlete, patient and senior citizen shares.

Medicine can treat an asthma attack. It can manage a heart attack. It can stabilize COPD. But the better intervention is preventing unnecessary exposure in the first place.

Sometimes the most important medicine is not swallowed or injected.

Sometimes it is simply the air we breathe.
