What triggers migraines?
Migraine triggers vary by person and can include sleep changes, skipped meals, stress, hormones, alcohol, caffeine changes, weather, and light.
Migraine triggers are personal. One person may react to missed sleep, another to alcohol, and another to several small factors stacking together.
Triggers are not the same as causes. Migraine is a neurologic disease; triggers are factors that may help start an attack in someone who is already susceptible.
Common trigger categories
- Sleep changes
- Skipped meals or fasting
- Dehydration
- Stress or post-stress let-down
- Menstrual hormone changes
- Alcohol
- Caffeine withdrawal or too much caffeine
- Bright or flickering light
- Loud sound
- Strong smells
- Weather or barometric pressure changes
- Intense exercise in some people
Triggers can stack
One glass of wine may not trigger an attack on a well-rested day, but it might matter after poor sleep, skipped lunch, stress, and a weather change. That is why tracking context is more useful than blaming one factor every time.
Track patterns, not one-off coincidences
A single attack after one food, storm, or stressful day does not prove a trigger. Track repeat patterns and avoid broad restriction unless the pattern is strong or a clinician recommends it.
Early symptoms can look like triggers
Food cravings, yawning, neck stiffness, fatigue, mood changes, and light sensitivity may be prodrome symptoms that happen before pain. If you crave chocolate before an attack, for example, the craving may be part of the migraine starting rather than the chocolate causing it.
What to do with a suspected trigger
Track it for several weeks, then test one reasonable change at a time. Keep the changes healthy and sustainable. If attacks are frequent or disabling, do not rely on trigger avoidance alone; ask about acute and preventive treatment.
