The advisory highlights the disproportionate impact of heatwaves on informal workers and residents of slum settlements. These communities often lack access to cooling systems, leading to heightened physical distress during extreme heat events. The absence of statutory master plans and green spaces in urban areas further intensifies heat-trapping conditions. Vulnerable populations, including low-income outdoor workers, face increased health risks such as heat exhaustion and heatstroke. Municipal bodies also struggle with limited financial resources and technical capacity to implement effective climate resilience measures.
