The health benefits of sex extend well beyond the bedroom. Turns out that sex is good for you in ways you may never have imagined.
1. 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.
2. 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.
3. 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.
4. Sex Reduces Prostate Cancer Risk
Frequent ejaculations, especially in 20-something men, may reduce the risk of prostate cancer later in life, Australian researchers reported in the British Journal of Urology International. When they followed men diagnosed with prostate cancer and those without, they found no association of prostate cancer with the number of sexual partners as the men reached their 30s, 40s, and 50s.
But they found men who had five or more ejaculations weekly while in their 20s reduced their risk of getting prostate cancer later by a third.
Another study, reported in the Journal of the American Medical Association, found that frequent ejaculations, 21 or more a month, were linked to lower prostate cancer risk in older men, as well, compared with less frequent ejaculations of four to seven monthly.
5. Sex Helps You Sleep Better
The oxytocin released during orgasm also promotes sleep, according to research.
And getting enough sleep has been linked with a host of other good things, such as maintaining a healthy weight and blood pressure. Something to think about, especially if you’ve been wondering why your guy can be active one minute and snoring the next.
