（中央社台北23日电）纵慾寻欢或搞一夜情原本就有危险，如今想偷吃的人又多了个担心的原因，就是心脏病发作的风险可能比较大。

报导指出，对不常做爱的人而言，因此心脏病发作的短期风险恐怕增加近乎3倍。较常有性行为的人则可减低引发心脏病的危险，这代表幸福的夫妻可能比较占优势。7 H9 M' X* {' q- T

The relative risk of heart attack caused by a burst of activity falls by around 45 per cent for each additional time a person indulges in it a week. The risk of sudden cardiac death also falls by 30 per cent.

Like any physical activity, sex can increase the heart rate and blood pressure, which means the heart has to work harder. As a result, sex carries the same risk of triggering heart trouble as equally energetic forms of physical activity.rs238848.rs.hosteurope.de9 u& B' G+ e V. c* j
