Irregular sleep

Irregular sleep-wake syndrome involves different and disorganized periods of sleeping and wakeful behavior.

Sleep-wake syndrome - irregular

Some people have an irregular sleep-wake pattern because of a problem with brain function, the body's circadian pacemaker (internal clock), or other reasons. 

In other people, such as shift workers and travelers who change time zones frequently, outside factors cause this syndrome.
