[Time; July 22, 2016] Smoking, even socially, is linked to an increased risk of brain bleeding, according to a new study reported in the journal Stroke. That seems to be especially true for women, who are known to have a higher risk for brain bleeding than men.
The study involved data from 65,521 people in Finland who answered survey questions for an average of 45 years. Researchers found that men and women who smoked had nearly three times higher risk for brain bleeds—where blood seeps through the lining between the surface of the brain and the tissue underneath—than people who never smoked. The risk even applied to social smokers, and it increased steadily from light to heavy smoking. Women seemed to be especially affected. Women who smoked showed a nearly 3.5-times higher risk of such bleeding, while men had a 2.2-times greater risk. Even women smoking one to 10 cigarettes a day had a nearly three times higher risk of brain bleeding whereas men smoking a similar amount had a nearly two-times higher risk.
