When it comesto sex, there’s no other month like August.
Lingerieretailer Ann Summers reported a 40 per cent rise in sales last August asshoppers took advantage of the holiday period to boost their sex lives.
Meanwhile,researchers from Boston State Hospital in the U.S. have found that summer sunat least doubles levels of the sex hormone testosterone, boosting a flagginglibido.
当涉及到性时，没有另外一个月像八月那样。
伴随着购物者利用长假时期以提高他们的性生活，女性内衣零售商Ann Summers报告说去年八月的销售额上升了40％。同时，美国波士顿州立医院的研究人员发现，夏天的太阳，至少两倍程度的提高了性激素睾酮的水平，提高了正在衰退的性欲。
Morefertile: The amount of sex you have is important. The more often you make love,the better quality your sperm will be
This is thoughtto be because the sun’s rays trigger vitamin D production, which in turn boostsproduction of the hormone.
And if anotherexcuse is needed, it’s well known that sex burns calories — just this week asurvey found that 87 per cent of women named sex as their favourite way toexercise (shopping came second).
But there aremany other benefits, too. Here some of the country’s leading experts revealsome little-known facts about why sex is good for your health.
生育力更强：你拥有的性生活的数量是很重要的。你做爱的频率越高，你的精子质量将会较好
通常认为是因为太阳射线启动体内维生素D的生产，这反过来又提高了激素的产量。
如果我们需要另外一个理由，众所周知的性爱能够燃烧卡路里 - 就在本周的一项调查发现87％的妇女认为性爱是她们最喜欢的锻炼方式（购物排在第二）。
但是，它也还有许多其他的好处。这里一些全国著名的专家揭示了一些鲜为人知的关于为什么性爱有益于健康的事实。

IT’SA GOOD WAY TO TEST YOUR EYES
Sex relaxes themuscles and alleviates neck and shoulder tension, says Dr Arun Ghosh, a GPspecialising in sexual health at the Spire Liverpool Hospital. Andsurprisingly, it might also tell you whether you need glasses.
这是一个很好的测试你视力的方式
一个石塔利物浦医院从事性爱健康研究的普通开业医生，Arun Ghosh 博士说，性爱能够放松肌肉，减缓颈部和肩部的紧张。令人惊讶的是，它同样能告诉你是否需要戴眼镜。
‘I’ve hadpatients complain of poor vision after sex. What’s happened is that, like allthe other muscles in the body, their eye muscles have relaxed and areperforming at their true ability, rather than straining and squinting as theywould normally.’
So if yoursight goes blurry after sex, it’s worth going for an eye test.
我有患者抱怨性生活过后视力变弱。那是发生了什么事，就像身体的全部其他肌肉一样，他们的眼部肌肉放松，并以他们的真正的能力发挥作用，而不是像他们通常那样伸张和眯起来。
所以如果性生活过后你的视野变得模糊，很值得做一次视力测试。
ITPROTECTS AGAINST HEART DISEASE
它可以保护预防心脏病
Havingsex three times a week could halve the risk of heart attack or stroke
Sex can have aprotective effect on the heart. A study at Queen’s University in Belfast foundthat having sex three times a week could halve the risk of heart attack orstroke.
一周做爱三次可能会使心脏病或着中风的风险减半
性爱对心脏有保护作用。贝尔法斯特皇后大学的一项研究发现，一周做爱三次可能会使心脏病或着中风的风险减半
。
Another studyin Israel found that women who had two orgasms a week were up to 30 per centless likely to have heart disease than those who didn’t enjoy sex or didn’torgasm.
以色列的另一项研究发现，一个星期有两次高潮的妇女比那些没有享受性生活或没有性高潮的妇女较少可能性患心脏病的概率最高可达30％。
Dr Lisa Turner,a sex and relationship therapist, says: ‘One theory is that these womenmay have felt depressed, which has been linked with an increased risk of aheart attack.
'The endorphinsreleased during sex also neutralise the stress hormones in the body, which arelinked to heart disease.’
And the oldcliche of sex causing heart attacks?
性爱和关系治疗师，Lisa Tumer博士说：“有一种理论是，这些妇女可能感觉到情绪低落，这与提高了的心脏病发作的风险有关。
“性交时释放的内啡呔，也中和了体内的应激激素，这与心脏病是相关联的”。
性爱的老模式导致心脏病发作？
‘It’s a verylow risk — it accounts for less than 1 per cent of all deaths,’ says Dr GrahamJackson, consultant cardiologist at the London Bridge Hospital and chairman ofthe Sexual Advice Association.
伦敦桥医院会诊医生心脏病专家和性咨询协会会长，Grahan Jackson 博士说：“这是一个非常低的风险 – 在所有死亡人数中占不到1％”。
However, ifyou’re over 50, overweight and unfit, there is a risk to your heart — just asthere would be if you suddenly and vigorously took up any form of exercise.
然而，如果你已经超过50岁，超重且不适，对你的心脏来说是一种风险 - 就像如果你突然充满活力的从事任何形式的运动那样。
‘What alsoincreases the risk is extra-marital affairs, and this has been proven by threelarge studies,’ says Dr Jackson.
“婚外情也增加了该风险，这已经被三个大型研究证明，”杰克逊博士说。
‘In fact, thisaccounts for 75 per cent of heart-related deaths from sex, 90 per cent of whichare older men. It’s thought the combination of high-fat foods and alcohol —wining and dining — combined with vigorous exercise, often with a youngerpartner, is what tends to trigger the heart event.’
“事实上，这占了75％由于性爱造成的涉及心脏的死亡，其中90％是老年男性。通常认为高脂肪的食物和酒精的组合 -美酒和美食 – 加上剧烈运动，往往与一个年轻性伙伴，倾向于引发心脏疾病“。
IT’LLSTRENGTHEN YOUR BONES
U.S. researchfound menopausal women who had sex every week had oestrogen levels twice ashigh as their abstaining counterparts.
The hormone hasa protective effect in bone health and a lack of it after the menopause hasbeen linked with osteoporosis.
‘Regular sexincreases the production of oestrogen,’ says Dr Peter Bowen-Simpkins of theRoyal College of Obstetricians and Gynaecologists.
它会加强你的骨骼
美国研究发现每周都有性生活的更年期妇女的雌激素水平是没有性生活的更年期妇女雌激素水平的两倍。
这种激素对骨骼健康有一定的保护作用，绝经后骨质疏松症也跟缺乏该激素相关。
“规律的性生活会增加雌激素的产量”，皇家学院妇产科的Peter Bowensimpkins 医生说。
ITMAKES YOU MORE FERTILE
‘I’m oftenasked whether penis length affects fertility and the good news is no,’ says DrGhosh.
But the amountof sex you have is important. The more often you make love, the betterquality your sperm will be.
‘If you’retrying to conceive, you need the sperm to be as fresh as possible — not stuffthat’s been sitting in the prostate for three or four days,’ he adds.
它使你的生育力更强
医生Ghosh说，”我经常被问到阴茎长度是否影响生育，好消息是没有。
但你拥有性生活的数量是很重要的。你做爱的频率越高，你精子的质量越好。
“如果你正尝试受孕，你需要尽可能新鲜的精子 - 在前列腺没有东西停留三四天，”他补充说。
ITSTAVES OFF PROSTATE CANCER
Researchers atNottingham University have found that men who enjoy a regular sex life in their50s are at lower risk of developing prostate cancer. ‘Clearing the prostate outregularly is the reason behind this,’ says Dr Ghosh.
‘The link wassuggested after research showed that monks appear to have a higher chance ofdeveloping prostate cancer.’
它关闭前列腺癌的来源
英国诺丁汉大学的研究人员发现在50多岁的人享受有规律的性生活的男人能降低前列腺癌的发展的机率。Ghosh医生说：“背后的原因就是定期清空前列腺”。
“该链接的建议基于研究表明僧人似乎有更高的发生前列腺癌的可能性。”
IT’LLHELP YOU QUIT SMOKING
Here's a simpleway to get your man to kick his smoking habit — remind him that it causes thepenis to shrink and can cause impotence.
Erections areall about good blood flow, and lighting up worsens blood flow to the spongytissues in the penis, says Raj Persad, consultant urological surgeon at BristolRoyal Infirmary.
它会帮助你戒烟
下面是一个简单的让你的男人抛弃他吸烟习惯的好方法 - 提醒他吸烟会导致阴茎萎缩并可导致阳痿。
布里斯托尔皇家医院泌尿科外科医生Raj Persad说，勃起都是关于新鲜血液的流动，使得变坏的血液流向阴茎海绵组织。
‘As a result,they become starved of oxygen and the delicate cells die away. They then becomefibrotic — forming scar tissue — which is less elastic and less able to expandduring an erection than regular healthy tissue.’
“结果，他们成为缺乏氧气脆弱的细胞而消失。然后，他们变得纤维化 - 形成瘢痕组织 - 缺乏弹性，较普通健康组织而言在勃起时只能较小程度地膨胀“。
Smoking is alsoa known cause of erectile dysfunction as it causes hardening of the arteriesand hampers good blood flow.
A study of more7,000 Chinese men, published in the American Journal of Epidemiology, foundthat the more cigarettes smoked a day, the higher the risk of impotence.
吸烟也是一个造成勃起功能障碍的著名的原因，由于它会导致血管硬化并阻碍良好的血液流通。
美国流行病学杂志上发表的对于多于7000名中国男子的研究表明，一天吸的香烟越多，阳痿的风险越高。
IT’SA NATURAL SEDATIVE
For a man, apowerful orgasm is the equivalent of having a 2-3mg shot of diazepam (orValium), says Dr Ghosh.
‘And diazepamworks as a muscle relaxant which is why so many men nod off after finishing —there really is a biological reason.’
它是一个天然的镇静剂
Ghosh 医生说，对于一个男人，一个强大的高潮相当于服用2 - 3mg 剂量的地西泮（或者安定）。
地西泮作为一种肌肉松弛剂发挥作用，这就是为什么这么多男人在射精后点头 - 真的有一种生物的原因。“
Theendorphins released during sex can really help treat depression and clear themind
Women benefitemotionally, too.
‘The endorphinsreleased during sex can really help treat depression and clear the mind.
‘One endorphinis serotonin, known as the happy hormone; the other is the endogenous endorphinand this creates a sense of bliss (orgasm) for five to ten seconds in men — andup to four or five minutes in women, which is excellent for mental health.
‘One theory isthat women orgasm for longer because their cervix is contracting to draw thesperm up towards the ovaries.’
性交时释放的内啡呔确实能帮助治疗抑郁症和清理头脑
也有益于妇女的情绪，。
“在性交时释放的内啡呔确实能帮助治疗抑郁症和清理头脑。
“一种内啡肽是血清素，被称为快乐激素；另一种是内源性内啡肽，它会在男子体内制造一个5至10秒的幸福感（高潮） - 对于妇女则高达四五分钟，这对于心理健康是极好的。
“有一种理论认为女性性高潮时间更长是因为她们的子宫颈配合吸引精子在子宫的着床。”
ITGUARDS AGAINST INCONTINENCE
Providing thata woman is fairly active during sex, then it’s a good workout for her pelvicfloor muscles, says Dr Gillian Vanhegan, a spokesman for the Royal College ofObstetricians and Gynaecologists.
The musclesthat stem the flow of urine, reducing leakage and incontinence, all benefit andthis reduces the risk of stress incontinence and prolapse later in life, bothof which are very common.
‘After havingchildren many women don’t have the time to do dedicated pelvic floor exercises,so sex provides a natural workout.’
它能够抵御失禁
Gillian Vanhegan 医生，英国皇家妇产科学院发言人说，假如一个女人在性生活中相当活跃，那么对她的盆底肌肉是很好的锻炼。
该肌肉止住尿道的尿液，减少渗漏和大小便失禁全部有益，降低了以后的生活中应力性尿失禁和下垂的风险，这两者是很常见的。
“许多妇女有孩子后，没有时间做专门的骨盆底肌肉练习，因此性生活提供了一种天然的锻炼。”
ANDFINALLY...USE IT OR LOSE IT
结语 使用它或者失去它
‘Just likesmoking or diabetes, a lack of regular blood flow to the penis will over timecause some of the tissues to die,’ says Mr Persad.
Persad 先生说：“就像吸烟或糖尿病一样，阴茎常规血液流通的不足会随着时间的推移造成一些死亡的组织，”。
Indeed, Finnishresearch has confirmed that men who had sex less than once a week at the startof the study were twice as likely to develop erectile dysfunction as those whohad it at least once a week.
事实上，芬兰的研究已证实，在研究开始，性生活少于每周一次的男子可能发展为勃起功能障碍的概率是每周至少一次的男子发生该疾病的两倍。
In the study of1,000 men aged between 55 and 75, those who had sex three or more times a weeklowered their risk fourfold.
There’s noreason not to enjoy a full sex life in old age, adds Dr Jackson.
在1,000名年龄介于55岁和75岁的男子的一项研究中，那些每周三次或三次以上性生活的男子使他们患病的风险降低了4倍。
Jackson医生补充说，我们没有理由在老年不享受一个完整的性生活。
‘We have somepatients in their 80s taking Viagra-type drugs and studies have shown that aregular sex life can prolong life — it’s basically another form of exercise.
‘There seems tobe a myth that you’re past it once you hit 65, but that’s rubbish.’
“我们有患者在80岁时服用伟哥类药物，研究表明有规律的性生活能延长生命 - 它基本上是另一种形式的锻炼。
“似乎有这样一个神话，一旦你到了65岁你将失去它，但这句话垃圾。”
