​Most headaches have a genetic basis. Some may also be sensitive to certain triggers that can lead to a headache.
Lessen the impact of a headache by identifying triggers and avoiding them:

• External environment i.e. changes in weather, bright lights, smells and loud sounds
• Emotion, mood and stress
• Diet e.g. alcohol, cheese, chocolate, monosodium glutamate (MSG), citrus fruits
• Hormonal changes due to menstruation, menopause, oral contraception, hormone replacement therapy

Keeping a headache diary can help identify factors that may contribute to the headache and the pattern of the headache.
