1. Helps Keep Your Immune System Humming
“Sexually active people take fewer sick days,” says Yvonne K. Fulbright, PhD a sexual health expert.

People who have sex have higher levels of what defends your body against germs, viruses, and other intruders. Researchers at Wilkes University in Pennsylvania found that college students who had sex once or twice a week had higher levels of the a certain antibody compared to students who had sex less often.

2. Boosts Your Libido
Longing for a more lively sex life? “Having sex will make sex better and will improve your libido,” says Lauren Streicher, MD. She is an assistant clinical professor of obstetrics and gynecology at Northwestern University’s Feinberg School of Medicine in Chicago.

For women, having sex ups vaginal lubrication, blood flow, and elasticity, she says, all of which make sex feel better and help you crave more of it.

3. Improves Women’s Bladder Control
A strong pelvic floor is important for avoiding incontinence, something that will affect about 30% of women at some point in their lives.

Good sex is like a workout for your pelvic floor muscles. When you have an orgasm, it causes contractions in those muscles, which strengthens them.

4. Lowers Your Blood Pressure
Research suggests a link between sex and lower blood pressure, says Joseph J. Pinzone, MD. He is CEO and medical director of Amai Wellness.

“There have been many studies,” he says. “One landmark study found that sexual intercourse specifically (not masturbation) lowered systolic blood pressure.” That’s the first number on your blood pressure test.

5. Counts as Exercise
“Sex is a really great form of exercise,” Pinzone says. It won’t replace the treadmill, but it counts for something.

Sex uses about five calories per minute, four more calories than watching TV. It gives you a one-two punch: It bumps up your heart rate and uses various muscles.

So get busy! You may even want to clear your schedule to make time for it on a regular basis. “Like with exercise, consistency helps maximize the benefits,” Pinzone says.

6. Lowers Heart Attack Risk
A good sex life is good for your heart. Besides being a great way to raise your heart rate, sex helps keep your estrogen and testosterone levels in balance.

“When either one of those is low you begin to get lots of problems, like osteoporosis and even heart disease,” Pinzone says.

Having sex more often may help. During one study, men who had sex at least twice a week were half as likely to die of heart disease as men who had sex rarely.

7. Lessens Pain
Before you reach for an aspirin, try for an orgasm.

“Orgasm can block pain,” says Barry R. Komisaruk, PhD, a distinguished service professor at Rutgers, the State University of New Jersey. It releases a hormone that helps raise your pain threshold.

Stimulation without orgasm can also do the trick. “We’ve found that vaginal stimulation can block chronic back and leg pain, and many women have told us that genital self-stimulation can reduce menstrual cramps, arthritic pain, and in some cases even headache,” Komisaruk says.
