（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。: X& @1 t% |, F$ {3 O6 m5 U& f

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。" w( A' V# J- ^, a) E2 Z+ s& {

「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。www.csuchen.de' \5 K v& |( e5 p

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。
