The millions of acres of corn grown in states like Ohio, Illinois and Iowa perspire just like any other plant. A single acre sweats 3,000 to 4,000 gallons of water every day.

An acre of corn can release 3,000 to 4,000 gallons of water into the atmosphere a day, increasing humidity levels.

The process -- known by the scientific term "evapotranspiration" -- is the natural process by which plants move water from the roots of the plant to the surface, according to Ohio State University. The water then evaporates into the atmosphere, making the local region feel more humid.

In Iowa, corn pumps out "a staggering 49 to 56 billion gallons of water into the atmosphere each day" throughout the state, the National Weather Service said. That can add 5 to 10 degrees to the dew point, a measure of the humidity in the air, on a hot summer day.

While the humidity is low in Central Ohio today, you're probably seeing stories on your news feed about corn sweat impacting the Midwest.
