Like the Non-24-hour sleep–wake disorder, the Delayed Sleep Phase Syndrome can be described as a disturbance on the circadian rhythm of the biological clock. In healthy persons, the circadian rhythm has twenty four hours (the length period of a day), and is completely submissive to the day and night cycle. In individuals who suffer from such disabilities, the biological clock, besides having an intrinsic period that is probably longer than twenty four hours, is primarily desynchronized with the day and night cycle, so the biological clock steps out of its regular compass, developing its own independent anomalous schedule. So, as an example, it’s normal for people suffering from the most severe form of the dysfunction to feel sleepy only by five in the morning. They will obviously have trouble in getting up early to start their daily activities, even if they use several alarm clocks in their attempts to wake up. To fulfill the demands of a regular day job, from 8 am to 17:30 pm, is certainly an enormous and troublesome challenge. After some time, it’s very common for individuals who deal with this condition to be classified as nocturnal, while it is also normal for them to develop a distinct aversion to sunlight, the blue color of the sky, and everything related to the daylight as well, which comes as a progression to the symptoms of the dysfunction.

Without medical help, though, DSPS becomes progressively worse, and an individual suffering from this condition can lose completely the control of his life. If you suffer from this dysfunction – or another sleep disorder, since all of them are equally debilitating – medical treatment is fundamental, besides extremely necessary, for you to have a better quality of life, and to regain, at least relatively – since, being a chronic condition, it is for life, so, there is no cure – the happiness, the normality and the joy of existence.
