World Sleep Day is an annual, global call to action about the importance of healthy sleep. The focus of WSD is to bring cognizance to the many burdens of sleep problems, as well as the importance of healthy sleep. WSD publicly displays efforts being taken toward prevention and management of sleep disorders. Created and hosted by World Sleep Society, World Sleep Day is an internationally recognized awareness event bringing researchers, health professionals and patients together to recognize sleep and its important impact on our health. WSD is chaired by committee member Liborio Parrino, MD, PhD, Associate Professor of Neurology at Parma University, Italy; with support from World Sleep Society’s staff and a full committee.

WSD events take place globally, but are listed together online at In the past, World Sleep Day delegates have worked locally to spread awareness of sleep issues by hosting special events, translating materials, distributing booklets and pamphlets on sleep, hosting school events, press conferences and securing media coverage around the world. Delegates also created content such as public lectures and workshops, appearances on local television and radio shows, booklets, pamphlets, promotional videos, and press releases on sleep.

  • World Sleep Day is an annual event to raise awareness of sleep disorders and the
    burden that they place on society. World Sleep Day 2019 will be held on Friday,
    March 15, 2019.
  • Most sleep disorders are preventable or treatable, yet less than one-third of sufferers
    seek professional help. (4)
  • Sleep problems constitute a global epidemic that threatens health and quality of life for
    up to 45% of the world’s population. (3)
  • Better understanding of sleep conditions and more research into the area will help
    reduce the burden of sleep disorders on society.
  • Three elements of good quality sleep are:
    • Duration: The length of sleep should be sufficient for the sleeper to be rested
      and alert the following day.
    • Continuity: Sleep periods should be seamless without fragmentation.
    • Depth: Sleep should be deep enough to be restorative.

2019 will mark the 12th annual World Sleep Day on March 15, 2019!
