[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。

　　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。. {1 j% e' p# M/ m% y. }8 h( B/ n6 n0 k

　　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。

　　「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。

　　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。

　　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。4 y; v: J* ?. C' h0 j# v- o4 A

Having a fling or one-night stand is already a risky business. But now there is another reason for adulterers to worry.

They are probably more at risk of having a heart attack.

Occasional sexual activity is much more likely to cause a heart attack than regular sex, researchers have found.rs238848.rs.hosteurope.de9 A) B/ `9 _3 r3 a0 W% s9 r

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

Those who have sex more often reduce the risk of it causing a heart attack – which means happily married couples could have the advantage.! C, V6 F) j0 Q) R& C$ [

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." N( V, l8 ~% M

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

The risk after ‘episodic’ sexual activity – the kind associated with affairs and one-night stands – is 2.7 times higher.

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.人在德国社区$ G* x: d: }8 ]7 ?

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.

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.: G# A5 P5 r; \6 J

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

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.’
