Contrary to the popular cliché, “Not tonight, I have a headache,” one study found that not all headache sufferers avoid sexual activity. In fact, migraine sufferers reported higher levels of sexual desire according to the research done by the Wake Forest University School of Medicine and colleagues. Why? “Our study suggests that sexual desire and migraine headaches may be influenced by the same brain chemical,” said Timothy Houle, Ph.D., lead author and research assistant professor of anesthesiology.
