[社会新闻] 偷情风险大

（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。3 P+ j% N# x8 R2 ~/ \, d' l

　　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。

　　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。" d, D$ q2 O+ C( k

　　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。6 L/ k" m: a& T# v( h6 i3 v* K. q

　　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 x; E8 s @ w+ t" ?

　　「美国医学会期刊」（Journal of the AmericanMedical Association）刊出的评论报告說，不论是在性行为或体能活动方面越活跃的人，心脏病发的风险就越低。5 ?/ f1 ~. ]) c' t2 z

　　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。/ ?( R6 F! @& f9 M1 l

　　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。) ^- X& i3 @ u3 ^

Occasional sexual activity is much more likely to cause a heart attack than regular sex, researchers have found.

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

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.

Overall, there is a 3.5 times higher risk of such activity triggering a heart attack.5.35.249.647 G3 S# G2 O! K( ?% ]8 L( t- N

The risk after ‘episodic’ sexual activity – the kind associated with affairs and one-night stands – is 2.7 times higher., C0 d6 c) q8 H( j4 F0 J

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.人在德国社区) r3 B% ]# b, x9 x& c* c

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.5.35.249.64. a) S* r2 z3 y4 l% c1 a# Z! B0 s

The researchers, from the Tufts Medical Centre and Harvard School of Public Health, stress that the number of heart attacks actually caused by sex will be low.( ^8 u2 I3 H3 c6 f2 V

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.5.35.249.64- T0 q# c: A# s

The higher risk during activity is then offset by a lower ‘everyday’ background risk for people who are fitter because they are more active.- e6 ~* K+ H2 f, v$ i/ K

Amy Thompson, senior cardiac nurse at the British Heart Foundation, said: ‘It’s important to distinguish between what causes a heart attack, and what potentially triggers it.

'The study shows sex can act as a trigger, but this doesn’t change our viewpoint on the health benefits of physical activity.

‘To help keep your heart healthy you should aim to do 30 minutes of moderate-intensity activity, such as a brisk walk or gardening, at least five times a week.

'Sex places no more stress on the heart than climbing a couple of flights of stairs, so people with or without heart disease need not avoid it.’
