Many clusterheads are hit with Hypnic Headaches, or headaches while they sleep. These have been shown to occur primarily in the REM (rapid eye movement) of sleep that is associated with dreaming. During REM, the body is most immobilized, and Apnea is most common.

Clusterheads also tend to have Delayed Sleep Phase Syndrome - their circadian cycles are shifted. This may be related to a disturbance in Melatonin, a hormone that is involved in sleep and circadian regulation.

Melatonin is the most useful agent for restoring normal sleep in cluster headache patients, although it does not work for all.
