When you're in the mood, it's a sure bet that the last thing on your mind is boosting your immune system or maintaining a healthy weight. Yet good sex offers those health benefits and more.

That's a surprise to many people, says Joy Davidson, PhD, a New York psychologist and sex therapist. "Of course, sex is everywhere in the media," she says. "But the idea that we are vital, sexual creatures is still looked at in some cases with disgust or in other cases a bit of embarrassment. So to really take a look at how our sexuality adds to our life and enhances our life and our health, both physical and psychological, is eye-opening for many people."

Sex does a body good in a number of ways, according to Davidson and other experts. The benefits aren't just anecdotal or hearsay -- each of these 10 health benefits of sex is backed by scientific scrutiny.

Among the benefits of healthy loving in a relationship:

1. Sex Relieves Stress

A big health benefit of sex is lower blood pressure and overall stress reduction, according to researchers from Scotland who reported their findings in the journal Biological Psychology. They studied 24 women and 22 men who kept records of their sexual activity. Then the researchers subjected them to stressful situations -- such as speaking in public and doing verbal arithmetic -- and noted their blood pressure response to stress.

Those who had intercourse had better responses to stress than those who engaged in other sexual behaviors or abstained.

Another study published in the same journal found that frequent intercourse was associated with lower diastolic blood pressure in cohabiting participants. Yet other research found a link between partner hugs and lower blood pressure in women.
2. Sex Boosts Immunity

Good sexual health may mean better physical health. Having sex once or twice a week has been linked with higher levels of an antibody called immunoglobulin A or IgA, which can protect you from getting colds and other infections. Scientists at Wilkes University in Wilkes-Barre, Pa., took samples of saliva, which contain IgA, from 112 college students who reported the frequency of sex they had.

Those in the "frequent" group -- once or twice a week -- had higher levels of IgA than those in the other three groups -- who reported being abstinent, having sex less than once a week, or having it very often, three or more times weekly.
3. Sex Burns Calories

Thirty minutes of sex burns 85 calories or more. It may not sound like much, but it adds up: 42 half-hour sessions will burn 3,570 calories, more than enough to lose a pound. Doubling up, you could drop that pound in 21 hour-long sessions.

"Sex is a great mode of exercise," says Patti Britton, PhD, a Los Angeles sexologist and president of the American Association of Sexuality Educators and Therapists. It takes work, from both a physical and psychological perspective, to do it well, she says.
