（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。

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。5 q$ }" w2 k% H! D1 g

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。8 l0 p7 K7 }0 y) d D

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。# e, M. v* T; m% f) _

But the more active an individual is, either sexually or physically, the lower the risk falls, said the review in the Journal of the American Medical Association.

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