（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。9 J- ?) Q! r7 V" {' | D' @, }7 X1 y! w

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。

报导說，一般而言，从事这种活动时引发心脏病的风险，为一般活动的3.5倍。而在进行「偶发的」性行为，像是外遇偷吃或搞一夜情后，风险则达2.7倍。5 Z/ c& K7 r) E" V

「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。
