The inaugural World Sleep Day was held on March 14, 2008. The event was organized by the World Sleep Committee of the World Association of Sleep Medicine, now known as the World Sleep Society, in order to raise awareness of the medical, educational and social aspects of sleep problems.

World Sleep Day is observed around the world with various events and activities such as discussions, presentations, exhibitions etc. Special emphasis is put on sleep disorders and their prevention. International health organizations remind people about the problems such as lack of sleep and insomnia, focusing on the fact that good sleep is a vital part of a healthy lifestyle. More than 10% of the population in developed countries suffer from insomnia, and every other person on the planet has one or more symptoms of sleep disorders.

Through World Sleep Day, the World Sleep Society raises awareness of the better understanding and preventability of sleep disorders, as well as of the fact that sleep problems have become a global epidemic that threatens the health of almost half of the world’s population.
