Migraine Trigger Tracker Score

Migraines are complex neurological events that rarely have a single cause. Research shows that migraines are typically triggered when multiple risk factors occur together — a concept known as the “migraine threshold.” When enough triggers combine, the threshold is crossed and a migraine occurs.

Common Migraine Triggers

Triggers vary by individual, but the most widely reported include:

• Sleep disruption: Too little or too much sleep is one of the most consistent triggers. Irregular sleep schedules disrupt circadian rhythms and lower your threshold.
• Stress: Both acute stress and the “let-down” period after stress (e.g., weekends after a hard week) are common triggers.
• Dehydration: Even mild dehydration (1–2% body weight) can trigger migraines in susceptible individuals.
• Skipped meals: Drops in blood sugar from going too long without eating are a well-documented trigger.
• Hormonal changes: Many women experience migraines around menstruation, ovulation, or during hormonal medication changes.
• Weather and pressure changes: Barometric pressure drops and high humidity are reported triggers by many sufferers.
• Caffeine: Both too much caffeine and caffeine withdrawal can trigger migraines.
• Bright lights and strong smells: Sensory overexposure is both a trigger and a symptom.
• Alcohol: Red wine, beer, and spirits — especially those containing histamines and sulfites — are classic triggers.

The Threshold Model

No single trigger reliably causes a migraine every time. Instead, triggers accumulate. A person may tolerate poor sleep alone, but if they also skip a meal and are stressed, the combination crosses their threshold.

Using This Tool

Rate your exposure to common triggers over the past 24 hours. The calculator scores each factor and gives you an overall risk level. Use it regularly to identify your personal patterns. Keeping a trigger diary is one of the most effective tools for migraine management.
