According to the journal Headache, (1998;38:497-506), about 7 million adults in the United States suffer from frequent headaches, which is defined as having a headache 15 days out of the month. Almost 6% of women and nearly 3% of men suffer from frequent headache. This accounts for a lot of missed work and lost productivity. Frequent headache is more common among women than men, but the difference between the sexes is not as great as it is in migraines. Migraine headaches affect women at a much higher rate than men.
