The heatwave has posed significant risks to public health, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions. In New Jersey, most of the 22 fatalities occurred in central and northern counties, with victims ranging in age from their mid-30s to 80s. Heat-related deaths were also reported in Illinois and Mississippi, with causes linked to heat stress and exposure. The extreme temperatures have disrupted public events, including the cancellation of the Independence Day parade in Washington, D.C., and led to numerous heat-related illnesses requiring medical attention (The Guardian, 2026).
