（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。人在德国 社区1 @$ x# \$ ]1 K

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。1 Y) M$ L+ F/ z

「美国医学会期刊」（Journal of the AmericanMedical Association）刊出的评论报告說，不论是在性行为或体能活动方面越活跃的人，心脏病发的风险就越低。

美国塔弗兹大学医学中心（Tufts Medical Center）及哈佛大学公共卫生学院（Harvard School ofPublic Health）的研究人员强调，实际因性爱引起心脏病发的人数并不多。

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。* B8 V% D7 O" c: y1 X! |# z

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.5 }: @) Z9 |$ V4 ~$ [

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.
