A self-reported sleep diary (1 to 2 weeks) will be important to show the consistent delay in sleep timing. The person with DSWPD will often complain of daytime sleepiness because of the need to wake up well before the time of spontaneous awakening, resulting in an insufficient amount of sleep. The person will typically fall asleep very late in the night (around 1 to 6 AM) and, if there is no social or professional obligation to wake up at a certain time, will only wake up in the late morning or afternoon.
