（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。7 ]4 g! ?/ X% e: A% Q& |6 D

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。3 I) d1 h3 w6 U+ F6 |; y" U

The relative risk of heart attack caused by a burst of activity falls by around 45 per cent for each additional time a person indulges in it a week. The risk of sudden cardiac death also falls by 30 per cent." U2 W1 X8 z1 U" r! q

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.
