Letter from the President
Dear Members and Colleagues,
The year 2025 was a truly historic one for World Sleep Society. The commitment and energy of our membership are on full display in this annual report, which makes it such a pleasure to share with the world sleep community.
Early in the year, the Governing Council released a Strategic Plan that succinctly identifies our society’s vision, mission, and strategic goals. The Strategic Plan is aligning the growing portfolio of World Sleep Society programs and initiatives, and I encourage you to review it.
Many milestones and successes followed this in 2025, including:
- The release of the Sleep and Circadian Health Education Curriculum
- The organization of the 18th World Sleep congress, the largest ever
- A significant update to the bylaws with a revitalized committee structure and process for Affiliate Society collaboration
- The launch of our new online Learning Center
The following report will detail many more achievements. Taken together, World Sleep Society activities in 2025 demonstrate a renewed focus and collaborative spirit among our membership.
We are carrying strong momentum into 2026, and I invite you to join us! Now is the time to join our workgroups and activities. The coming year brings new opportunities to connect with international colleagues from all continents and advance sleep health worldwide. We increase collaboration with WHO. We increase education efforts, especially in countries with young sleep societies. We develop educational programs for all professional groups active in sleep medicine, sleep research, and circadian research.
I sincerely thank our individual members and Affiliate Societies for their contributions in 2025, and I look forward to a prosperous new year with you all in 2026.
Best regards,
Thomas Penzel, PhD
President, World Sleep Society
