Prolonged summer heat and humidity in Central Illinois pose a threat to the health and well-being of Central Illinois residents. The Moultrie County Health Department reminds residents to remain informed and prevent heat-related illnesses, stay weather aware, and avoid mosquito-borne diseases.
Prolonged Heat and Humidity: A Dangerous Combination- Central Illinois is enduring one of its most intense summers in years. A persistent heat dome has trapped scorching temperatures and humidity across the region, with heat index values soaring above 105° on several days.
This “oven‑like” atmosphere has been intensified by corn sweat. Corn sweat refers to the moisture released by corn fields during pollination, which contributes to the “mugginess” in the environment. The elevated moisture content of the atmosphere also reduces our body’s ability to cool down effectively.
