The 2023 Theme: Sleep Is Essential for Health

The theme for this World Sleep Day is Sleep is Essential for HealthJust like eating well and exercising, sleep is a behavior that is foundational to one’s physical, mental, and social well-being. However, sleep is not yet commonly considered an essential behavior for good health. World Sleep Day is an opportunity to promote sleep health alongside thousands of other sleep health professionals and advocates. When we all promote sleep health and #WorldSleepDay together, our combined effort is greater than the sum of its parts. Spread the word about sleep health on World Sleep Day, and help elevate the conversation around sleep!




World Sleep Day® is designed to raise awareness of sleep as a human privilege that is often compromised by the habits of modern life.

World Sleep Day is an annual event, intended to be a celebration of sleep and a call to action on important issues related to sleep, including medicine, education, social aspects and driving. It is organized by the World Sleep Day Committee of World Sleep Society and aims to lessen the burden of sleep problems on society through better prevention and management of sleep disorders. World Sleep Day is held the Friday before Spring Vernal Equinox of each year. Future dates will be: Friday, March 17, 2023 and Friday, March 15, 2024

Who created World Sleep Day?

The annual awareness event was started by a group of dedicated health care providers and members of the medical community working and studying in the area of sleep medicine and research. The goal of the first World Sleep Day was to bring together sleep healthcare providers to discuss and distribute sleep information around the world. The first co-chairs of World Sleep Day were Liborio Parrino, MD, Associate Professor of Neurology at Parma University, Italy and Antonio Culebras, MD, Professor of Neurology, Upstate Medical University, and Consultant, The Sleep Center, Community General Hospital, Syracuse, New York, USA.

Why was World Sleep Day created?

Time and time again, sleep medicine professionals and researchers came up against the belief that sleep was not important enough in personal health and well-being to be a priority. That coupled with society’s 24/7 flow, the founders of this awareness event aim to celebrate the importance of healthy sleep.
