If we were to recall the major events in 2013, many will remember a PSI reading surpassing 400,
right here in our island city.
You may not have been sufficiently prepared then, but this article will give you a clearer picture of
haze and how to protect yourself against it.
Haze and its symptoms
Haze is an atmospheric condition where particles, smoke, dust and moisture suspend in the air
obscuring visibility.
When inhaled, these fine particles can cause irritation to the nose, throat, airways, skin and eyes.
You may sneeze, or have runny nose, irritated eyes , dry throat and dry cough after inhaling the air
pollutants.
These symptoms are usually mild if the haze is not severe and will subside when you stay indoors
and limit your exposure to haze.
Find out how you can relieve the following symptoms:
- Irritation in the throat and dry cough
- Drink sufficient water and suck on lozenges. Your pharmacist may recommend more
effective cough mixtures and lozenges. - Consult a doctor if the cough persists for more than seven days, or is accompanied
by thick, greenish phlegm and high fever.
