Migraine Triggers and How to Avoid Them

Migraine affects over 1 billion people worldwide and is the second leading cause of disability globally. Identifying personal triggers is one of the most effective strategies for reducing attack frequency, as individual trigger profiles vary considerably.

The most well-documented triggers include: hormonal changes (particularly estrogen fluctuations during menstruation), sleep disruption (both too little and too much sleep), dehydration, skipping meals, bright or flickering lights, strong smells, weather changes (especially barometric pressure drops), alcohol (particularly red wine), caffeine (both excess and withdrawal), and high psychological stress.

Keeping a migraine diary for 2–3 months is the gold standard for identifying personal triggers. Record date and time of attacks, duration, severity, potential triggers (food, sleep, stress, weather), menstrual cycle, and medications taken. Apps like Migraine Buddy can simplify this process.

Prevention strategies supported by evidence include: maintaining regular sleep and meal schedules, staying hydrated, reducing caffeine intake gradually, stress management through mindfulness or cognitive behavioral therapy, and prophylactic medications (propranolol, topiramate, amitriptyline, or CGRP antagonists) for frequent attacks. Talk to a neurologist if you have more than 4 migraines per month.
