Since 2004, the International Association for the Study of Pain (IASP) has designated the third Monday of October as "World Pain Day." This day marks the launch of the annual World Anti-Pain Year campaign, with a theme released each year. For 2024, the theme for "World Pain Day" is "Sex and Gender Disparities in Pain."

Pain is a signal from the body and an inescapable aspect of life. As the earliest and most frequently experienced subjective internal sensation in one's life—"pain"—is a common issue faced by humans. World Pain Day serves as a reminder to focus on pain issues and raise awareness about pain management. Proper pain management not only improves the quality of life but also helps prevent potential health risks.
