Why Starbucks Should Not Franchise Brothels

Drinking coffee, having sex are triggers that raise rupture risks for brain aneurysm

From drinking coffee to having sex to blowing your nose, you could temporarily raise your risk of rupturing a brain aneurysm — and suffering a stroke, according to a study published in Stroke: Journal of the American Heart Association.

Dutch researchers identified eight main triggers that appear to increase the risk of intracranial aneurysm (IA), a weakness in the wall of a brain blood vessel that often causes it to balloon. If it ruptures, it can result in a subarachnoid hemorrhage which is a stroke caused by bleeding at the base of the brain. An estimated 2 percent of the general population have IAs, but few rupture. Calculating population attributable risk — the fraction of subarachnoid hemorrhages that can be attributed to a particular trigger factor — the researchers identified the eight factors and their contribution to the risk as:

• Coffee consumption (10.6 percent)
• Vigorous physical exercise (7.9 percent)
• Nose blowing (5.4 percent)
• Sexual intercourse (4.3 percent)
• Straining to defecate (3.6 percent)
• Cola consumption (3.5 percent)
• Being startled (2.7 percent)
• Being angry (1.3 percent)

"All of the triggers induce a sudden and short increase in blood pressure, which seems a possible common cause for aneurysmal rupture," said Monique H.M. Vlak, M.D., lead author of the study and a neurologist at the University Medical Center in Utrecht, the Netherlands.

Risk was higher shortly after drinking alcohol, but decreased quickly, researchers said...
