In Singapore, people are experiencing economic losses due to heat stress, which is expected to almost double to $1.64 billion in 2035 compared to pre-pandemic levels in 2018. A recent study by the National University of Singapore found that there has been a decline in workforce productivity across different economic sectors in the country.

In 2018, heat stress led to an average productivity decrease of 11.3% in sectors such as services, construction, manufacturing and agriculture. This trend is predicted to worsen over time, with a projected 14% drop in productivity by 2035. Workers exposed to adverse environmental conditions such as working under the sun or with heat-generating machinery will face even greater economic losses.

The study estimates that for each hot day, workers could experience an average income loss of S$21 per worker due to reduced productivity during working hours. The HeatSafe project is the first large-scale study in Singapore and the region to analyze the impact of rising heat levels on both individual health and macroeconomic productivity.

Singapore’s rapid rate of warming, which is twice the global average, has caused extreme heat levels in the country. The UV index reached “extreme” levels twice within four days, raising concerns about the impact of such intense heat on residents. This level of heat exposure not only affects cognitive and physical abilities but also poses a risk to Singapore’s fertility rate, which is already at a historically low level.

Globally, scientists have warned that the world has exceeded a critical warming threshold, moving the planet into an era of extreme heat. The recent findings underscore the urgent need to address the impact of rising temperatures on both individual health and macroeconomic productivity for both Singaporeans and people worldwide.

To combat this issue effectively, policymakers must take immediate action by developing strategies that promote resilience against extreme weather events and ensure adequate protection for workers exposed to adverse environmental conditions while providing support for research and development into innovative solutions for mitigating heat stress’s effects on human health and economies.
