Sleep Is Essential for Health
Just like eating well and exercising, sleep is a behavior that is foundational to one’s physical, mental and social well-being. “Just because sleep is a natural behavior does not mean that sleep should be taken for granted,” says Fang Han, MD, co-chair of World Sleep Day 2023. Co-chair Lourdes DelRosso, MD, PhD adds that “People should think about sleep like they do other important healthy behaviors such as exercise – as something to reflect upon and, when appropriate, improve so that one can feel better and remain healthier over time.”

The Burdens of Unhealthy Sleep and Their Disparities
Unhealthy sleep has been linked to many harms to human health – including cardiometabolic disease, infectious diseases, brain and neurological diseases, traffic and occupational safety, and mental disorders – and these harms fall disproportionately on the marginalized and vulnerable worldwide.

World Sleep Society empowers its members to better understand, raise awareness of, and encourage action regarding global sleep health. “There is a critical need for sustained, focused collaboration among international experts, advocates, and policy decision-makers to advance global sleep health. Through World Sleep Day and other initiatives, the World Sleep Society provides resources and networking opportunities for this important work,” says Phyllis C. Zee, MD, PhD, president of World Sleep Society.

World Sleep Day Partners Support Global Sleep Health
World Sleep Day 2023 has partnered with organizations that share our mission to raise awareness of sleep health.

Scientists at Idorsia Pharmaceuticals Ltd have been researching the science of sleep for over 20 years and firmly believe that sleep is one of the three key pillars of health, alongside diet and exercise.

Jean-Paul Clozel, MD and Chief Executive Officer of Idorsia, says, “Idorsia is proud to support World Sleep Day 2023, and is committed to working alongside World Sleep Society to stress that ‘Sleep is Essential for Health’. At Idorsia, we know that sleep is a key pillar of good health and having a good or poor sleep can make all the difference on how you feel and function the next day. Considering people spend approximately a third of their lives asleep, it is surprising that common sleep disorders, like chronic insomnia, are some of the most neglected medical conditions seen in family practice. Idorsia is working to raise awareness that chronic insomnia is a serious medical disease and highlighting the toll it can take on an individual’s physical and mental health as well as the associated health complications, such as heart disease, stroke, and diabetes.”

Claire Bertin, PhD, says “Consumer Healthcare at Sanofi fully supports the mission of World Sleep Day 2023, celebrating healthy sleep and raising awareness of sleep’s critical importance to health, particularly mental well-being. Good sleep has benefits for the increase of memory, concentration, as well as for stronger immunity. We are committed to sharing this message and empowering individuals worldwide to self-care and enhance their sleep health.”
