Clearing the air: Why Singapore's haze problem is an eldercare crisis in plain sight

Eldercare operators should be building air quality into their operating environments. 

Over the past several months, residents across Yishun, Clementi, Woodlands, Tampines, and Bukit Merah have woken up to the acrid smell of burning.

As recently as 20 March, the National Environment Agency (NEA) confirmed hotspots with smoke plumes in Central Sumatra and Johor, warning that dry and warm conditions over Singapore and the surrounding region are expected to persist.

Daily maximum temperatures are forecast to reach 35°C to 36°C, and with prevailing north-easterly winds, NEA has cautioned that there may be an increase in hotspot activity and a continued risk of smoke haze. This follows a pattern that has played out repeatedly since January as episodes in February pushed Singapore’s 24-hour pollutant standards index (PSI) to a recent high of 69, and conditions are now worsening again.

These events are not anomalies. They are part of a recurring pattern, and for Singapore's elderly population, the stakes are higher.

For older adults with compromised respiratory systems, cardiovascular conditions, or weakened immune responses, sustained exposure to polluted air can trigger acute exacerbations of chronic obstructive pulmonary disease (COPD), increase hospitalisation risk, and accelerate cognitive decline in those with existing neurological conditions.

A PSI reading that a healthy 30-year-old shrugs off may represent genuine clinical danger for an 80-year-old in a nursing home. Singapore's Ministry of Health projects that one in four Singaporeans will be aged 65 or above by 2030: A cohort whose respiratory vulnerability will only grow as our regional haze problem persists.

What makes this harder to manage is where our elderly spend most of their time.

Unlike the general population, who can choose to stay indoors, limit outdoor activity or relocate temporarily, residents of eldercare facilities and nursing homes do not have that luxury. They live in shared spaces with communal dining halls, activity rooms, and corridors. Environments where outdoor air quality directly translates into indoor air quality, unless active mitigation is in place. 
This is not a new problem. But it remains a persistently under-discussed one.

Operators of eldercare facilities carry enormous responsibility for the respiratory environments they maintain, yet air quality management in these settings rarely receives the same attention as food safety, fall prevention, or infection control protocols.

Perhaps because haze comes and goes. The effects on any individual resident are perhaps difficult to attribute directly. Or perhaps simply because the problem has lacked visible, practical solutions.

That is beginning to change. The growing recognition of airborne infection and pollution risk and the previous COVID-19 pandemic may have pushed facility operators to think more seriously about the air their residents breathe every day, not just during haze alerts.

The question for the eldercare sector is no longer whether air quality management matters – it is whether operators are treating it with the same rigour they apply to other areas of clinical risk.
Ventilation and consumer-grade air purifiers are no longer considered sufficient for clinical environments.

The industry needs to move beyond reactive protocols. Waiting for an NEA advisory before assessing indoor air quality in a nursing home is the equivalent of waiting for a food poisoning outbreak before reviewing kitchen hygiene standards. The advisory tells you the air outside is compromised. By then, the air in the corridor is already compromised, too.

Eldercare operators should be building air quality into their standard operating environments,  from facility design and HVAC specifications to ongoing monitoring and response protocols. Consumer-grade air purifiers are not sufficient for clinical-grade environments housing immunocompromised residents. The bar needs to be higher, and it needs to be set explicitly.

There is also a policy dimension that deserves more attention. Singapore has invested significantly in ageing-in-place infrastructure and in fall prevention programmes, nutritional standards, and dementia care pathways. These are all great commitments, but the air quality in the spaces where our elderly actually live has not received the same structural focus. NEA monitors, advises, and updates, whilst MOH sets care standards.

However, the specific questions of indoor air quality in licensed eldercare settings are: What standards apply, how compliance is assessed, and what interventions are mandated during haze events remain an area where clearer guidance would serve both operators and residents.

The current situation is marked by drier weather linked to the Northeast Monsoon and wind patterns carrying smoke from fires in Sumatra and Kalimantan, which means that haze risk is not going away this season. For operators who have not yet embedded air quality management into their facility protocols, the window to act proactively is narrowing.

We should not be reacting when the haze arrives. The interventions need to be in place already before the air quality index climbs – especially for Singapore’s elderly.
