Delayed Sleep Phase Syndrome - Sleepchannel

Delayed Sleep Phase Syndrome - Sleepchannel: "Delayed sleep phase syndrome results from a desynchronization between the patient's internal biological clock and the external environment. Unlike jet lag, this desynchronization is not activated by travel or change in external environment. Rather, the patient's propensity to fall asleep is simply 'delayed' in relation to that of the general public. Subsequently, a patient with DSPS is desynchronized with the routine that governs most of his or her life"
