There are two main kinds of strokes, ischemic and hemorrhagic.
For years, researchers have studied the link between oral contraceptive pills (OCPs) and strokes in women.
Now, though, data suggests that OCPs may actually lower the risk of stroke.
It also took into consideration how long they were on hormonal birth control, if at all.
Researchers measured stroke incidents in the women a total of 12,000 ischemic strokes compared to the data.
And higher estrogen levels overall also meant lower risk, not just longevity.
