（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。

研究人员审查14篇关于心脏病发的研究后发现，若从事任何形式的「偶发」体能活动，也就是个人很少做的事情时，心脏会处于受压力的状态。

报导說，性爱就像任何的体能活动，会增加心跳速率及血压，代表心脏必须更卖力运作。因此，性爱引发心脏毛病的风险，与相同强度体能活动引发心脏病的风险是一样的。

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.2 G7 o0 ]* U3 c5 t7 v* Z! F+ [

The researchers, from the Tufts Medical Centre and Harvard School of Public Health, stress that the number of heart attacks actually caused by sex will be low.

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.

The higher risk during activity is then offset by a lower ‘everyday’ background risk for people who are fitter because they are more active.
