You'll Boost Your Immune System
Screw Emergen-C: Sex is the best way to prevent the common cold. Past research has shown that one of the big benefits of orgasm is that it boosts your immune system. A study of college students showed that those who had sex once or twice a week had immunoglobulin levels 30 percent higher than those who were abstinent. Just maybe don't have sex when you're sick...nobody wants to sneeze mid-romp and spread those germs around.
Your Pain Threshold Will Be Higher
You may not orgasm every single time you have sex, and that's totally fine. (Although, can we get a slow clap for this woman who made a resolution to have more Os with her partner?) Here's one reason to go for gold anyway: Another benefit of orgasm is that it produces a pain-blocking effect, so you won't be as sensitive to pain (like when you accidentally stub your toe on the way to the bathroom), says Dr. Beverly Whipple, a sex educator, researcher, counselor, and coauthor of The G Spot and Other Discoveries About Human Sexuality.
That said, there is one exception: "Women who eat a diet high in spicy foods don't always get the pain-blocking benefit because the capsaicin found in chili peppers prevents it from occurring," says Whipple. In other words, lay off the hot stuff. (If you want to spice it up in the bedroom instead, consider trying one of these best sex positions for your zodiac sign.)
You May Live Longer
A study conducted in South Wales over the course of 10 years examined the relationship between the frequency of orgasm and mortality among middle-aged men, who were asked about their physical health in addition to the frequency of orgasms. At the 10-year follow-up, they found that those who had two or more orgasms a week had a 50 percent lower mortality risk than those who had less-frequent orgasms. Studies that have since followed have shown a positive association between sexual intercourse and women's longevity as well, so keep on keepin' on. (DYK your relationship status can also help predict your lifespan?)
You'll Help Regulate Your Cycle
A Planned Parenthood report showed that several studies have linked regular sex—meaning once or twice a non-menstruating week—to more regular periods, along with relief from menstrual cramps when it's that time of the month. Translation: Get busy now so you can Netflix and actually chill later. (If your period is all over the place, one of these things could be causing your irregular cycle.)
You'll Feel Happier
No shocker here, though it's always nice to have a little scientific research to back this up: People who regularly have sex—orgasm or not—are happier, according to a study in the Journal of Psychosomatic Research. The researchers looked at 4,000 women in the U.S. and examined their mood, sexuality, and menstrual cycle. They found strong links between sexual interest and an overall sense of well-being. And those who had higher senses of well-being also had a stronger sex drive and overall higher quality of life.
You Could Be More Likely to Conceive
For those trying to start a family, timing can play a crucial role: In a report in the Archives of Sexual Behavior, women who have orgasms during sex after their male partner's orgasm retained more sperm than those who never hit the big O or hit it before their partner. Researchers say it likely has to do with the release of oxytocin that occurs as a benefit of orgasm. But that's not all: Dr. Whipple says that sex can also help create a healthy pregnancy overall, and has been proven to help more women carry to term.
You May Lose Weight
A study published in the Journal of Sex & Marital Therapy showed that frequent intercourse and sexual activity, whether with a partner or solo, has been connected to a smaller hip and waist circumference for both men and women. On top of feeling fierce AF, that also means getting busy can help lower your risk for serious health issues like heart disease and type 2 diabetes.
