Headaches - pt II by stan lord
But most headaches have simpler origins, according to Lawrence Newman, M.D., a practitioner with the Headache Institute in New York City. "Stress can be a trigger, as well as certain foods, odors and changes in the weather," he says. Headache triggers are thought to activate an existing chemical imbalance in the brain; the list includes alcohol, hunger, dehydration, altered sleep habits, bright lights, and such hidden food ingredients as casein, tyramine, nitrites, monosodium glutamate and aspartame. Emotional factors such as depression, anxiety and frustration may also lead to a nasty skull pounder.
Even exercise and sex, the curatives for so many problems, can give you pains in the neck and head. While exertion accounts for only 1 percent of the aching heads in the general population, it provoked 60 percent of the brain pain in a study of 129 university athletes that was published in the British Journal of Sports Medicine.
"Exertional headaches are pretty common among athletes," reports Thomas N. Ward, M.D., co-director of the Dartmouth/Mayday Headache Clinic in New Hampshire. "Sometimes they occur in people with a history of migraine, and they resemble those migraines."
Exertion headaches usually transpire during weightlifting, but they can also kick in after running a long distance or performing other physical activity, such as hurrying up a flight of stairs or having intercourse. The latter variation is prevalent enough to have been medically dubbed benign orgasmic headache, or, more informally, sex headache. (It hurts just as much, but it's a lot more fun to achieve.)
During exercise, the muscles of the head, neck and scalp require more blood, which results in a swelling of vessels that can cause discomfort. Also, some people stop breathing and bear down during strain, causing the vessels to expand even more. Studies of weightlifters have shown that, with maximal lifts, systolic blood pressure can reach levels that induce vasodilation and cause almost immediate head pain. Typically, exertion headaches move quickly from onset to peak intensity and are usually unpleasant enough to interrupt a workout.
