The session underscored the severe health risks posed by heatstroke, particularly during extreme heat events. Vulnerable groups, such as the elderly, outdoor workers, and individuals with pre-existing health conditions, are at heightened risk. Heatstroke can lead to rapid progression to multiorgan failure if not treated promptly. The discussion also highlighted the strain on emergency departments during heatwaves, with sharp increases in heat-related illnesses. The need for systemic preparedness and rapid response strategies was emphasised to mitigate these risks.
