Which of the following is listed as a migraine trigger?

• A. Hormones
• B. Regular naps
• C. Vitamin C supplementation
• D. Dairy products

Answer: (B)

Sleep timing and consistency can influence migraine activity. For some people, changes in when and how long they sleep—such as taking a regular nap during the day—can trigger a migraine by altering circadian rhythm or causing sleep inertia when waking. This is why regular naps appear as a listed trigger in questions focusing on sleep-related factors.

Hormonal fluctuations are another well-known migraine trigger, but this item highlights sleep/wake patterns, so nap timing fits the flags asked for. Vitamin C supplementation and dairy products are not commonly cited triggers for migraines in the same way sleep pattern changes are, which is why they aren’t chosen as the best answer here.
