A single cluster headache may last from 5 minutes to several hours. They frequently begin at the same time and are more common between 9 PM and 9 AM. They may disrupt sleep as they are more likely to occur during Rapid Eye Movement (REM) sleep. Episodes of cluster headaches may last from 2 to 12 weeks. Episodic cluster headaches are followed by a headache-free period of at least one month. Chronic cluster headaches can last for years without a headache-free month.
