World Sleep Day, established in 2008 by the World Sleep Society, takes place annually on the Friday before the March equinox to raise awareness about the importance of sleep for health and wellbeing. This year's theme, 'Sleep well, live better,' emphasizes the crucial role of sleep in achieving better physical and mental health outcomes. Scheduled for March 13, the event has grown significantly, now engaging 60 countries, compared to just one event in its inaugural year.

The celebration of World Sleep Day has gathered momentum over the years, primarily in Europe, followed by Asia and Latin America. This global initiative aims to educate people about the health benefits of adequate sleep and the risks associated with sleep deprivation. Organizations and health advocates are encouraged to participate in various activities and campaigns that promote good sleep habits and the overall necessity of rest in maintaining health.

In a related context, the American Heart Association has included sleep in its 'Life's Essential 8' list, which comprises critical factors for cardiovascular health and prevention. Sleep was added as the last essential item in 2022, reinforcing the growing recognition among health organizations of the pivotal role sleep plays in human health. The link between sleep, overall well-being, and specific health outcomes like heart health highlights why sleep should be a priority in wellness and lifestyle discussions.
