During which state are cluster headaches most likely to occur?

During waking hours

After caffeine consumption

When the person falls asleep

Cluster headaches are most commonly experienced during the nighttime, particularly when individuals are falling asleep or are in the middle of their sleep cycle. This is largely due to the body's natural circadian rhythms, which can influence headache patterns. Many people with cluster headaches report that they often wake up suddenly from sleep due to the intense pain. The unique characteristic of these headaches is that they tend to occur in clusters or cycles, often following a specific schedule, making nighttime episodes particularly prevalent.

While cluster headaches can occur in relation to various other activities or times of day, the significant association with sleep and nighttime onset is a distinguishing feature that supports the idea that they are most likely to occur when a person falls asleep.
