General practitioners in central Singapore said patient visits for haze-related coughs and eye irritation ticked up on Thursday as the National Environment Agency recorded unhealthy 24-hour Pollutant Standards Index readings in the central region.

Bernama reported PSI between 73 and 105 across the island at 6pm, with the central band above 100. NEA’s advisory for Friday forecast high-moderate to mid-unhealthy levels as smoke plumes from southern Sumatra continued to drift in on southeasterly winds.

What clinics are seeing

Three GP groups contacted by InfoHandle described more same-day appointments for throat discomfort and asthma reviews, especially among elderly residents in HDB estates without air conditioning. None reported acute respiratory failures, but nurses restocked N95 masks faster than a typical week.

Children’s clinics said parents asked whether outdoor Formula 1 events remain advisable; doctors referred them to NEA’s health advisory bands rather than issuing blanket bans.

How this haze spell compares

The Straits Times noted this is the first prolonged unhealthy spell since October 2023, driven by drier conditions linked to El Niño and the Indian Ocean Dipole. NEA warned that fires in Kalimantan and Sumatra could keep sending smoke toward Singapore if winds hold.

MOH activated additional haze surge capacity in hospitals earlier in the week, according to parliamentary replies cited in local coverage. The move pre-positions beds and respiratory supplies before emergency departments spike.

Practical guidance for households

When the 24-hour PSI enters the unhealthy range, vulnerable groups—seniors, pregnant women, young children and people with chronic lung disease—should minimise prolonged outdoor exertion. Healthy adults attending GP weekend events should monitor hourly PM2.5 if they have access to NEA’s app.

Air purifier sales rise in these weeks, but GPs remind patients that indoor smoking and dusty fans can also trigger symptoms. Closing windows helps only if indoor air is clean; otherwise recirculate through filtered devices.

Interaction with F1 crowds

Marina Bay crowds will spend hours outdoors near idling engines, which adds local particulates on top of regional haze. Race organisers typically monitor PSI for contingency messaging even when events proceed. Spectators with asthma should carry rescue inhalers and plan breaks in air-conditioned MRT stations.

When relief might arrive

NEA’s Friday forecast suggested a slight easing compared with Thursday, but meteorologists told local media that a broader monsoon shift may wait until late October or early November—later than in 2024 and 2025. That timeline means clinics could see elevated visits for weeks, not days.

If symptoms persist

Seek urgent care for chest pain, breathlessness at rest or high fever, which may signal infection rather than haze irritation alone. For routine coughs, telemedicine remains an option to avoid sitting in waiting rooms, but pharmacists caution against stacking multiple cough suppressants without a doctor’s review.

Employer policies

Some CBD firms reactivated work-from-home toggles for Friday when PSI entered unhealthy bands, while construction sites continued with mandatory mask breaks. Human-resource teams referenced Ministry of Manpower guidance on outdoor work rest cycles rather than issuing company-specific PSI thresholds.

Schools kept co-curricular activities outdoors where principals judged air quality acceptable, but several postponed National School Games trials, pushing athletes indoors for conditioning.

Pharmacy shelves

Pharmacists reported faster sales of saline nasal rinses and preservative-free lubricant eye drops. They cautioned against buying multiple brands of antihistamines without reading duplicate active ingredients, a common mistake when families panic-buy during haze weeks.
