（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。

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.4 r7 {; E- C5 S" }/ r

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