Well over 1000 abstracts will be presented in person at World Sleep 2023 in Rio de Janeiro. Join us in Rio to see the latest in sleep and circadian research!

Abstract submission has now closed, but you can still log into the submission system to update your abstract if necessary. The version of the abstract that we have on record at the start of the congress will be the version published in Sleep Medicine.

Abstract Submission

Abstract presentations are split into two formats: oral abstracts and poster abstracts.

Oral abstracts are 13-minute oral presentations, plus a limited question-and-answer time. Once accepted, oral abstracts are organized into sessions by theme (e.g. insomnia and treatment, sleep health across the lifespan, circadian misalignment and risk for cardiometabolic disease and performance). Slots for oral abstract presentations are more limited, making acceptance more competitive.

Poster abstracts are organized into 45-minute sessions during which the presenter must be present with their poster to discuss the work with attendees. Posters can be presented at almost any stage of research and provide an excellent opportunity for authors to discuss their methods and findings with other professionals.

All abstracts are published in a supplemental issue of Sleep Medicine, the official journal of World Sleep Society. Review the FAQ page for abstract submission and contact [email protected] with any questions.
