（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。* p# f E" g/ y4 M1 Q; W8 j
# ?9 R* b" W0 f7 w7 s 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。7 G% l! r& {8 v- Q6 p6 Z! I8 |2 k4 Y

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。

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.www.csuchen.de% x: e+ ^ N7 v: t9 S, B' }

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

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.

'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.’ |
