The site est aticulated around two big parts:
The nap and the management of sleep in insomnia deserve special entries on the homepage in order to make the access to the pratical advices easier.
Besides, there exist three interactive entrances;
While insomnia, fatigue and sleepiness worry mankind since its beginning, medical research has been interrested in sleep since only more or less fifty years.
While we spend a third (or a quarter) of our life sleeping, this medical specialty still remains neglected by medicine or pharmacy faculties where it only fills a very small amount of lessons.
Nowadays, sleep specialists are surprised to notice how little is the radiance of rudiments of sleep hygiene in managing modern lifestyle rythms.
The interrested reader can refer to the external links which are suggested on the introduction page.
Our experience in general medicine yet gives a particular lighting to that knowledge.
They bring us to try to redefine, in the light of recent knowledge in sleep medicine, some pathologies situated on the borders of psychology and physiology, and which often lead to unsatisfying diagnosis. 
The advances of sleep medicine regarding fatigue and sleepiness problems allow to put forward an hypothesis able to give a meaning to these medical charts that often harm the doctor-patient relationship.
A qualitative approach of sleep, defining the "hypo-sleep syndrome" is indispensable to the understanding, prevention and treatment of those pathologies.
The definition of unefficient sleep, not restful, is very different from that of insomnia and poses a problem of terminology that witnesses for the young age of sleep study.
We suggest to use the neologism of "hypo-sleep", to underline the difference between that problem and insomnia.
The insomniac subject suffers of not being able to initiate or maintain sleep, while the tired subject suffers of an unefficient sleep and is no more able to rest.
Other concepts about sleep deserve, too, to be better defined : siesta, fatigue, sleeping pill ...
Meanwhile, the sleep doctors know that there exists, at the present hour, no medication really able to induce a normal and efficient sleep, presenting no residual effects the next day, nor tolerance that forces to increase the dosis.
That lack of vocabulary leads us to suggest, in this website, some new definitions around the concept of functional insufficiency of sleep :
 The "IDEK" Syndrome (French) is very well described, with humour, by Doctor H. Raybaud on Esculape.com :"You suffer of "I don’t Exactly Know Syndrome". (One patient in four, according to him, receives no precise diagnosis.)
 This is alluding to an almost unveiled advert (seen on TV), for a well known sleeping pill (which recently got the speaker JL Delarue into trouble), and was broadcasted at 8.00 PM on the French TV channels.
In these pages, we describe the risk of the vicious circle of insomnia and the role played by that type of overwhelming advertising, overwhelming to sleep doctors.
