The heat wave poses severe risks to Chicago’s most vulnerable populations, including older adults, children, and those with chronic illnesses. Heatstroke, which can cause organ failure and death, is a primary concern when body temperatures exceed 104°F (40°C). Low-income communities, such as Chatham, Little Village, and Humboldt Park, are disproportionately affected due to inadequate housing and limited access to cooling resources. Historical events, like the 1995 heat wave that claimed over 700 lives, underscore the potential for public health disasters if adequate measures are not taken.
