The increased humidity caused by corn sweat primarily affects residents of the Midwest, where large-scale corn farming is prevalent. The added moisture in the air can make already high temperatures feel even hotter, increasing the risk of heat-related illnesses such as heat exhaustion and heatstroke. Vulnerable populations, including the elderly, children, and those with pre-existing health conditions, are particularly at risk. Outdoor workers and individuals without access to air conditioning may also face heightened discomfort and health risks during these conditions.
