What aspect of humor is analyzed in the study of gelotology?

Gelotology focuses on the physiological response to humor and laughter, examining how these reactions manifest in the body and affect overall well-being. Researchers in this field study laughter's effects on the body, including its impact on stress levels, immune response, and pain perception. Understanding these physiological aspects allows for insight into how laughter can serve as a therapeutic tool, contributing to physical health as well as emotional well-being.

The other aspects mentioned, such as the cultural significance of jokes, the impact on mental health, and the effectiveness of comedic performances, are related to humor but do not capture the core focus of gelotology, which is specifically centered around the body's physical reactions to laughter.
