Trigger avoidance in Cluster Headache management involves identifying and eliminating specific environmental, dietary, or behavioral stimuli that can precipitate or exacerbate headache episodes. Common triggers include alcohol, strong odors, changes in sleep patterns, and stress, which are thought to activate the trigeminovascular system and hypothalamic pathways involved in cluster headache pathogenesis. By systematically recognizing and minimizing exposure to individual triggers, patients can potentially reduce the frequency and intensity of cluster headache attacks.
