World Sleep Day
Good sleep is a pillar of health as vital as diet and exercise.
About
World Sleep Day is held annually in mid-March, organised by the World Sleep Society, to celebrate the benefits of healthy sleep and draw attention to sleep disorders. Sleep problems affect up to 45% of the world's population and have serious public health, safety, and economic consequences. The day promotes actionable messages for improving sleep quality.
History
World Sleep Day has been organised by the World Sleep Society since 2008, falling on the Friday before the spring equinox in the northern hemisphere.
