Sex, coffee and working out may raise the risk of a brain hemorrhage

Having sex, drinking coffee, working out. All are everyday activities that cause blood pressure to spike -- and may briefly raise the risk of a burst aneurysm.

That's according to a new study out of the Netherlands published in the journal 'Stroke'. But it's important to note that the increased risk of a stroke is only in certain people.

Only about two percent of the population is believed to have an aneurysm -- a balloon-like swelling in a brain artery that results from a weak spot in the artery wall. The overall risk of a rupture is normally small.

But even brief activities that raise blood pressure can temporarily boost the risk.

Coffee and vigorous exercise were the most commonly noted triggers -- followed by nose blowing, sex, drinking cola, being startled, and even anger. But researchers say that people should *not* stop drinking coffee or having sex.

The study simply shows that those activities are triggers.
