（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。7 g$ _- c7 z. F% L5 |- Z* [

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。6 s3 L1 j4 M/ I6 j7 G

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.7 N7 b8 n/ O2 }! c* w8 e7 u0 T
