The Institut National du Sommeil et de la Vigilance (INSV) is a French organization dedicated to raising awareness, sharing information and educating the public about sleep, sleep disorders and alertness. Its work presents sleep as an important public health issue and aims to make reliable information accessible to individuals, professionals and communities.

The INSV runs prevention campaigns and public events, including the annual Journée du Sommeil, and shares news, educational resources and guidance through its website. Its library covers sleep across different ages, sleep mechanisms, dreams, bedroom conditions, screens, nutrition, exercise, work, stress and travel across time zones. It also provides information on insomnia, sleep apnoea, narcolepsy and restless legs, alongside guidance on finding sleep centres in France.

The organization offers brochures and public-facing publications, as well as a document shop and resources for sleep centres and event organizers. Through partnerships, sponsorship opportunities, donations, conferences and webinars, the INSV brings together experts and the public to support better understanding and prevention of sleep-related difficulties.
