（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。

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。( ^, E- o- E" m; i; Z& x( W. P

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。

「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。

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.1 J( c) V8 @0 B% t
