Because headache is the most promiment caffeine withdrawal symptom, and people who may not be aware that they are experiencing relief of caffeine withdrawal when coffee makes their headache go away may believe that coffee helps with headaches, and thus recommend it to others, not being aware that caffeine only relieves headaches in caffeine dependent individuals and that caffeine is not a general remedy for headaches.
