Meeting History

The first SLEEP meeting was held in Columbus, Ohio, in June 1986. Since its inception nearly 40 years ago, SLEEP has become the world’s premier clinical and scientific meeting for sleep medicine, sleep and circadian research, and sleep health, attracting attendees from across the U.S. and around the world. The SLEEP exhibit hall also has become the leading showcase for the latest advances in sleep-related diagnostics and therapeutics. Each year, the APSS is proud to bring together a diverse and dedicated group of attendees, speakers, and exhibitors to contribute to the advancement of sleep medicine and sleep science.
