Cluster headaches are characterized by severe and excruciating pain that often occurs in cyclical patterns or clusters. These headaches can be triggered by various factors, but the distinctive nature of how they develop often involves a specific timeframe in relation to sleep.

In many cases, individuals who suffer from cluster headaches experience them after falling asleep, especially during the rapid eye movement (REM) stage of sleep. This phenomenon occurs because the body's physiological changes during sleep, particularly in the brain's neurotransmitter functions and circadian rhythms, can contribute to the onset of these headaches. The timing of the headache episodes often corresponds with nighttime sleep, which sets this option apart as the most relevant and commonly recognized trigger for cluster headaches.

By recognizing this relationship, individuals can better understand their headache patterns, which may aid in the management and potential treatment options for those who suffer from cluster headaches.
