Sex is good for you: For fighting cancer to the common cold it's just what the doctor ordered

As promised I am sharing this amazing article on sex and it’s health benefits that I found in the Daily Mail. I was so surprised that I had to pass it on.

Making love could be one of the few pleasures in life that is genuinely good for you, say researchers. Not only does a healthy sex life boost mood, but there is growing evidence to show it boosts your physical well-being, too - from increasing longevity to reducing the risk of erectile dysfunction and even heart attack. Only last month, researchers at Nottingham University concluded that men who kept up a regular sex life in their 50s were also at lower risk of developing prostate cancer. Making love could be one of the few pleasures in life that is genuinely good for you, say researchers. Not only does a healthy sex life boost mood, but there is growing evidence to show it boosts your physical well-being, too - from increasing longevity to reducing the risk of erectile dysfunction and even heart attack.

In fact, the research seems to suggest that men - particularly older men - benefit the most from healthy effects of sex. Feel-good hormones help explain some of the benefits, such as mood-boosting, but the explanation is not always obvious.
But one thing is clear, and this applies to both men and women: you need to be having sex regularly if you don't want to lose the ability. They had followed 1,000 men aged between 55 and 75 for five years and found that those who had sex less than once a week at the start of the study were twice as likely to develop erectile dysfunction (see below) as those who had it at least once a week. Those who had sex three or more times a week lowered their risk fourfold.
'Use it or lose it' was the advice given to older men by Finnish scientists recently.

As women get older their oestrogen levels drop, says Dr Peter Bowen-Simpkins, consultant gynaecologist at the London Women's Clinic and spokesperson for the Royal College of Obstetricians and Gynaecologists. This hormone is key to a woman's sexual enjoyment - lower levels can make sex uncomfortable, he explains. But American research found that menopausal women who had sex every week had oestrogen levels twice as high as their abstaining counterparts. 'Regular sex increases the production of oestrogen,' says Dr Bowen-Simkins. As long as other symptoms, such as dryness, are not a problem or have been treated, having more sex can decrease the risk of vaginal atrophy which can occur with age, he says.
So what else can a regular love life do for your health?

Heart
Sex can be good for your heart. The idea that men are more at risk of a heart attack during love-making is mostly misconception, say experts. Professor Peter Weisberg, medical director of the British Heart Foundation, says there is no evidence that men who have sex regularly in their 40s, 50s and beyond are at an increased risk of heart attack. 'As far as the heart is concerned, sex is just another form of exercise,' says Dr Graham Jackson, consultant cardiologist at Guy's & St Thomas' Hospital and president of the Sexual Dysfunction Association.
'In fitness terms, it's equivalent is going for a mile-long walk or climbing up and down two flights of stairs. If you're physically fit enough for that, there should be no increased risk during sex.'
A study at Queens University in Belfast found that having sex three times a week could actually halve the risk of heart attack or stroke.

However, if you are over 50, overweight and unfit, there is a risk to your heart - just as there would be if you suddenly and vigorously took up any form of exercise. Loving feeing: A study found those who had sex less than once a month had double the risk of dying prematurely than those who had sex twice a week.

Prostate
Prostate cancer is the most common cancer in British men, affecting 35,000 a year.
Previous research suggested that greater sexual activity was linked to a higher risk of prostate cancer, but findings from Nottingham University (published in the British Journal Of Urology International) suggest the opposite is true: that increased activity is protective for older men.
This backs up the findings of a major study five years ago by the National Cancer Institute, published in the Journal of the American Medical Association.
Previous studies have suggested the reduced risk is due to the release of toxins from the prostate gland. 'We can't say for certain that having regular sex can protect older men from prostate cancer, because such studies don't prove the mechanism through which risk is reduced,' says Dr Geoffrey Hackett, consultant urologist at Good Hope Hospital, Sutton Coldfield, and former chairman of the British Society for Sexual Medicine.
'But many men who maintain a regular sex life are also likely to maintain a healthy lifestyle in terms of regular exercise and a better diet. That's likely playing a bigger part in their prostate cancer risk reduction.'

Bones
'Testosterone levels have been found to increase during and after sex,' says GP Dr Sarah Brewer. 'This may provide some protection against male osteoporosis.'
Sexual activity can also protect you against other unwanted changes. Some scientists have linked low levels of sexual activity to structural changes in the penis or testicles which appear to reduce them in size. 'We know that men who don't have regular ejaculations or sexual intercourse have lower levels of testosterone,' says Professor Pierre Bouloux, consultant endocrinologist at University College London and the Royal Free Hospital. And if your testosterone levels fall and you don't get erections, there is some evidence that the penile tissues can lose some of their elasticity, which in turn could make them appear smaller.

Mood-lift: The neurotransmitter serotonin is the body's key anti-depressant and a major reason people smile after sex

Mood
The evidence suggests that the 'feelgood' effect of making love could be more about chemicals than sexual ability. 'During lovemaking and orgasm, a cocktail of endorphins (the body's natural mood-lifting opiates), neurotransmitters and hormones are released,' says Professor Nadir Farid, consultant endocrinologist and founder of the London Endocrine Clinic.
'Oxytocin, in particular, is a hormone released during and after sex that has been shown to make people more generous towards their partners and can also help induce calm and sleep,' he adds.
Oxytocin is called the 'cuddling' hormone because it's released after just 20 minutes of hugging. Women produce four times as much as men, for whom production is inhibited by the prevalence of the hormone testosterone, which drives libido.
Another key neurotransmitter is serotonin, says Professor Farid. 'Serotonin is the body's key antidepressant chemical and one of the major reasons people smile and feel happy and relaxed after sex.' Sexually active women in longterm relationships were less likely to be depressed than women who went without sex, according to a study of nearly 300 women by American psychologist Gordon Gallup and published in the Archives Of Sexual Behaviour.
Gallup speculated that semen contains several hormones which may have a mood-boosting effect when they are absorbed through the vaginal wall into the bloodstream.

Immunity
Having more sex might increase immunity from colds and flu.
Having sex once or twice a week has been linked with higher levels of immunoglobulin A, or IgA, a substance found in saliva and the nasal lining thought to help our immune systems fight colds and flu. In one study, scientists asked 11 volunteers how often they had had sex over the previous month, then measured levels of IgA in their saliva.

Those who had sex once a week or less had a slight increase, compared with those who abstained; but those who made love more often had 30 per cent higher levels.
Professor Ron Eccles, director of the Common Cold Centre and Healthcare Clinical Trials at Cardiff School of Biosciences, is not convinced, though, that sex itself is the key.
It's known that stress and anxiety can also make IgA levels go down, so according to Professor Eccles any connection between sex and colds may be related to other factors.
Cold cure? Having more sex might increase immunity from colds and flu.

Longevity
One of the largest studies on longevity and sex - conducted on Welsh men - found that those who had sex less than once a month had double the risk of dying prematurely than those who had sex twice a week. 'Sexual activity seems to have a protective effect on men's health,' says GP Dr Sarah Brewer. 'This may be linked with the effects of the master sex hormone, DHEA or dehydroepiandroterone, which is made in the adrenal glands and functions as a building block of other hormones such as oestrogen, testosterone and progesterone.
'DHEA levels rise just before orgasm and ejaculation to three times higher than normal, and some claim this is how regular sex can prolong your life.'

Fertility
For people trying to conceive, one of the biggest myths associated with fertility is that refraining from ejaculation boosts sperm mobility - the rate at which individual sperm can move forwards to penetrate an egg for fertilisation, says gynaecologist Dr Gillian Lockwood, medical director of Midlands Fertility Services. 'When sperm is hanging around in the epididymis, the long coiled tube in the back of the testes where sperm is stored, it dies off rapidly,' she says.
'Unless a man has a low sperm count, the more often he has sex, then the better the quality of his sperm.' Preliminary results of a small study two years ago, by Australian researchers, found that in men whose sperm showed significant DNA damage, daily ejaculation reduced this damage by 12 per cent. 'When it comes to sex for fertility, having sex little and often - at least every other night - is far better than lots of it on infrequent occasions.'
