With Indonesia’s Sumatra and Kalimantan battling wildfires over the past weeks, Singapore may be experiencing occasional periods of haze.
According to the National Environment Agency’s haze microsite, the 24-hour Pollutant Standards Index (PSI) levels rose to 93 in Singapore’s central region on Tuesday (Aug 25) noon.
A PSI of 101 indicates unhealthy air quality levels.
As Singapore experiences a drop in air quality in the recent days, some people may be feeling unwell.
So, how can people look after their health during this time?
HealthHub recommends checking hourly PM2.5 readings and daily PSI readings before deciding on outdoor activities such as runs or walks.
While it is still safe to continue outdoor workouts or activities if PSI and PM2.5 levels are in the normal range, the Ministry of Health (MOH) advises people to drink plenty of water if they are experiencing symptoms such as a dry and itchy throat.
If the outdoor air quality worsens, one should avoid going out and close all doors and windows to reduce exposure to haze particles. While air conditioners can help with air circulation and cooling, an air purifier is recommended to further reduce indoor particle levelz.
If the PSI reading is over 300 and you have to go outdoors, make sure to use an N95 mask – which can filter out even PM2.5 haze particles. Those with chronic lung or heart disease, or the elderly or pregnant, can also wear an N95 mask when the PSI reading is higher than 200.
Normal surgical masks – while not effective in filtering fine particles – can provide a barrier between the wearer’s nose and mouth, and larger irritants in the air, said MOH.
Those with chronic heart and lung conditions, as well as children and the elderly should take extra precautions during this period, even if pollution levels are not high.
This includes the measures mentioned earlier, alongside ensuring your medications are readily available and within reach.
If you develop symptoms or feel unwell, seek medical attention immediately.
