Chicago and Illinois are experiencing increased humidity due to 'corn sweat,' a phenomenon where cornfields release 4,000 gallons of water daily through evapotranspiration. This process raises heat indices near 100°F as temperatures rise into the 90s, with Illinois corn crops releasing 35 billion gallons of water daily. Heavy June rainfall in northern Illinois, combined with a heat wave, has intensified the effect early this summer.

Before air conditioning became common in mid-20th century US homes, people used ice blocks, fans, and cold drinks to stay cool. Historical records show iceboxes, mechanical cooling techniques, and frozen treats like ice cream were key methods. Recent heat waves highlight the growing necessity of air conditioning as temperatures set new records.
