You either sleep too much or not enough. In short, you sleep badly. You may be suffering from dyssomnia; Polysleep tells you more about it!
First of all, what is dyssomnia? It's in fact a broad category of sleep disorders that affect the quality or quantity of sleep, the best known of course being insomnia. This sleep deficiency is quite common (the number of messages talking about insomnia on social networks at 3 a.m. is proof of this!), but it's not the only dyssomnia; to be sure, on the other end of the spectrum we find hypersomnia, or excessive daytime sleepiness. A fantasy for some but a nightmare for those who suffer from it, hypersomnia includes disorders such as narcolepsy (those who can fall asleep anywhere, anytime), psychiatric hypersomnia and many others.
Finally, there are circadian rhythm sleep disorders (or sleep-wake disorders), the most well known of which is the famous jet lag. There are also the delayed sleep phase syndrome (you have trouble falling asleep regularly) or the advanced sleep phase disorder (you fall asleep between 6 and 9 p.m. for example, and wake up between 1 and 3 a.m.), as well as the hypernycthemeral syndrome (also non-24-hour sleep-wake disorder), which is, at least, a nice word to remember for Scrabble points!
What about parasomnia?
Dyssomnia is not to be confused with parasomnia, which is rather a set of abnormal behaviours during sleep, such as sleepwalking, that affect more children (17%) but still trouble 4% of adults. And since there is a genetic predisposition, chances are that Mini You will also suffer from it if you are or were sleepwalking! Parasomnias also include the nightmares and night terrors of toddlers.
In short, dyssomnia affects the quality and quantity of sleep; if you have trouble falling asleep on a regular basis, or if you sleep too much, don't hesitate to consult a doctor or a specialist!
