（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。9 T: `" k5 q! \; y0 B' i% y! z' o

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。

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。

Those who have sex more often reduce the risk of it causing a heart attack – which means happily married couples could have the advantage.

A review of 14 studies of heart attacks found the heart is under strain during any form of ‘episodic’ physical activity – something an individual only does rarely.

The higher risk during activity is then offset by a lower ‘everyday’ background risk for people who are fitter because they are more active.
