Regular 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.
- It boosts your 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.
- Regular 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.
- Regular sex improves heart health
While some older folks may worry that the efforts expended during sex could cause a stroke, that’s not so, according to researchers from England. In a study published in the Journal of Epidemiology and Community Health, scientists found frequency of sex was not associated with stroke in the 914 men they followed for 20 years. And the heart health benefits of sex don’t end there. The researchers also found that having sex twice or more a week reduced the risk of fatal heart attack by half for the men, compared with those who had sex less than once a month.
- Regular sex boosts self-esteem
Boosting self-esteem was one of 237 reasons people have sex, collected by University of Texas researchers and published in the Archives of Sexual Behavior. That finding makes sense to Gina Ogden, PhD, a sex therapist and marriage and family therapist in Cambridge, Mass., although she finds that those who already have self-esteem say they sometimes have sex to feel even better. “One of the reasons people say they have sex is to feel good about themselves,” she tells WebMD. “Great sex begins with self-esteem, and it raises it. If the sex is loving, connected, and what you want, it raises it.”
