（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。7 l0 x, o7 L2 Y- X

英国「每日邮报」（Daily Mail）报导，研究人员发现，偶发性行为比规律性行为容易导致心脏病发作。rs238848.rs.hosteurope.de; s" J( P6 p" G2 | h

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。8 E$ y7 k: O/ E; K+ B4 @; [

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。2 j5 m3 {) g# \' m# f8 [

「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。

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。rs238848.rs.hosteurope.de2 ], n- c/ Q+ s6 `: J
