(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。" n" ]/ S, a- c2 }

' W0 ~6 b7 Y6 i; i. N8 ^; F  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。; ?1 ~0 G& n) d) v( D( p6 m6 `

& M+ h$ f2 o3 w  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。

. |4 H' p% D( y5 c5 o2 m  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。

  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。# r, A( C, v+ ?# p1 H+ Q

  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。

The short-term risk of having a heart attack increases almost three-fold among those who rarely make love.

Overall, there is a 3.5 times higher risk of such activity triggering a heart attack.

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.- b5 H0 y' @4 O7 q1 w$ ?

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.  A% g0 X) w7 O, s

" F" s' a2 s) k: _1 W( U" u; JLike 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.
