Overview

Delayed Sleep Phase Disorder (DSPD) also known as Delayed Sleep Phase Syndrome (DSPS) is a Circadian Rhythm disorder where your internal body clock is not in sync with the sunrise and sunset. People with DSPD will often fall asleep in the early hours of the morning and rise late in the morning and into the afternoon. In some extreme cases, this can be very irregular and there will be no set sleep schedule. No matter how hard someone with DSPD tries to sleep earlier, it just isn’t possible 99.9% of the time. Waking up can also be very difficult for some, many people claim to not hear their alarm clocks and need someone to physically wake them up before rising naturally.
