2020 Annual Report

World Sleep Society is a nonprofit, membership-based organization representing sleep researchers and clinicians with programs focusing on awareness and education. Led by volunteers from around the world, we fulfill our mission to advance sleep health worldwide by encouraging education, research, and patient care, especially in regions where sleep medicine is less developed.

Though its roots go back to 1988, World Sleep Society (WSS) was created in 2016 when its two founding organizations, World Association of Sleep Medicine (WASM) and the World Sleep Federation (WSF), merged. View current officers and committees.

2020 Program Breakdown

World Sleep 2022

Rome, Italy | March 11-16, 2022

Extensive planning for the biennial congress took place in 2020. The location of Rome, Italy was selected with the Italian Association of Sleep Medicine being named as the host society. By the end of the year, the 2022 Program Committee had selected 14 keynote speakers ranging from pediatric sleep to insomnia to movement disorders, representing the most diverse set of keynote speakers to date. World Sleep Society committees are anticipating the symposia submission opening date of March 1, 2021 and expect the largest number of submissions to date. The website is kept current with updates on the congress.

Healthier Sleep Magazine

In 2020, World Sleep Society launched a public awareness magazine to act as a trusted source for improving sleep. Our first issue went to 16,481 individuals digitally and included 1,500 printed copies mailed. And with each issue, that number continues to grow. Leaders in the sleep medicine and research field subscribe to receive Healthier Sleep Magazine for use in their offices, waiting rooms, sleep labs, universities, hospitals, clinics and other various locations. We are pleased to offer this bimonthly magazine as a complimentary benefit to the public and our community. With a steady stream of subscriptions, the second digital issue is anticipated to go out to more than 20,000 individuals.

World Sleep Virtual Meeting

In 2020, we offered the latest in sleep medicine and research during this multi-day online event. The virtual meeting was and remains available at no cost to members. Sessions began on December 3-5, 2020, and will continue through December 2021.

At the December online event, we combined 40 speakers from 12 countries (28 speaking live virtually and 14 speaking in on demand recordings). With speakers and attendees combined, Virtual Meeting brought together individuals from 23+ countries. Participants had access to 18.3 hours of content for the December program (4.68 hours of on demand content; 13.65 hours of simulated live content.) More content will be added continuously throughout 2021 with the next virtual meetings scheduled for February 18, 2021, June 24, 2021 and September 16, 2021.
