According to the French National Institute of Sleep and Alertness (InSV), 1 French person in 5 suffers from insomnia, and up to 9% of these insomniacs are badly affected (poor quality sleep, difficulty falling asleep, multiple awakenings or waking too early).
On average, we spend one-third of our lives asleep.
Indeed, sleep is indispensable to the learning, memorisation, adaptation and growth functions, and is also very important to our state of well-being. Without it, we could not recover our physical and mental abilities.
On the 15th Sleep Day, to be held on Friday 27 March 2015 on the theme of “Sleep and Nutrition,” many public institutions and associations, including InSV, will be working to receive, inform and sensitise the general public.
Throughout the year, researchers at Inserm Unit 1028, the “Lyon Neuroscience Research Center,” and at Inserm Unit 846 are particularly involved in the research concerning sleep.
The chronobiology department of Inserm Unit 1028 take interest in light effects on sleep and biological clock. A recent study from the theam, led by Claude Gonfrier shows that the light spectrum can be optimized to enable the circadian system to synchronise and to maintain an appropriate sleep duration in extreme artificial lightning conditions.
