Definition of the word heavy breathing

The term "heavy breathing" originated from the sound produced when a person rapidly inhales and exhales with an audible intake and exhale of air, typically as a result of heightened physiological stimulation. In medical terminology, this rapid and deep respiration is known as hyperventilation, and it can be triggered by various factors such as exercise, excitement, anxiety, or pain. The usage of "heavy breathing" as a colloquial term dates back to the early 20th century, where it was used primarily to describe the sounds of labored breathing in animals or during military training drills. However, the idiom has since become popularly associated with romance novels and movies, where it is often used to describe the sounds of passionate lovemaking. In this context, "heavy breathing" carries a more erotic connotation, suggesting an intense and heightened physical response.
