If you're prone to headaches or migraines, this is information you should know.
New medical research offers new insight into what sets off excruciating headaches.
New findings suggest that weather and red wine can trigger the head pain, but not in all people; all the time.
Wines that contained higher levels of flavonoids, known as tannins which provide red wine's coloring --were more to blame than others.
A second study found that outside temperature also can trigger migraines, especially among people who are more sensitive to temperature.
Experts say, the association seemed more closely linked to cold rather than hot days.
The research was presented this week at the annual meeting of the American Headache Society in Los Angeles.
