Accra:Southeast Asia Rising temperatures pose significant risks to public health and workplace productivity, but practical heat-protection measures can mitigate these effects, according to a heat resilience expert.

According to BERNAMA News Agency, Professor Jason Kai Wei Lee, Director of the Heat Resilience and Performance Centre at the National University of Singapore, emphasized the need for Southeast Asians to reconsider their perception of being accustomed to hot weather. This belief, he argues, could hinder efforts to address the serious effects of heat exposure.

Prof. Lee highlighted that rising temperatures directly impact exercise, sleep, and eating habits, potentially compromising overall health. Fatigue and exhaustion are among the common warning signs. He noted that outdoor workers, especially gig workers paid per delivery, face significant health risks, while salaried workers may experience decreased productivity in uncomfortable conditions.

Thermal discomfort can also lead to increased risk-taking behavior, contributing to workplace accidents and injuries. Prof. Lee advocated for investment in heat protection measures, which could benefit both workers and employers by curbing such behaviors.

He suggested practical measures such as appropriate work-rest cycles, adequate hydration, access to shade, cooling equipment, and heat acclimatisation. Wearable devices using Internet of Things (IoT) technology could help identify individuals at higher risk, although Prof. Lee stressed that human adaptation has its limits. Addressing the root causes of climate change, particularly fossil fuel use, is essential.

Prof. Lee also noted that investment in heat protection should be seen not only as a preventive measure against heat-related illnesses but also as a means to improve productivity, reduce workplace accidents, and retain workers. He stressed that extreme heat could exacerbate existing challenges, including mental health issues, and that addressing its effects could enhance overall well-being across society.

He called on governments, employers, researchers, and communities to collaborate on developing practical solutions tailored to the needs of affected groups. Community participation and integration into public policy are crucial for building effective and sustainable heat resilience.
