8 Health Reasons to Have Sex (As If You Needed Them)

As promised in last week’s Hunter-Gatherer Fitness post, I’m stirring up the (apparently much awaited) subject of sex – specifically the benefits for physical and mental well-being. Uh, you mean coitus? Yup. Thanks to everyone who responded to the announcement with rousing enthusiasm as well as comments and questions.

What could be more Primal than sex, many of you have suggested. Absolutely right. It was probably one of Grok’s most valued pleasures. (Are people today much different?) For our part, however, we have new freedoms in a manner of speaking. Although we might honor the evolutionary imperative behind our primal appetites with eventual procreation, we’re not beholden to the natural odds with every tryst. As I’ve said many a time, I love studying and learning from the example of Grok and his kin. Nonetheless, I’m a happily modern man in this instance as much as any.

I’m not just talking hedonistic indulgence here (not that there’s anything wrong with that). There are genuine health benefits to be garnered after all. Today I’m after those copious “ancillary” benefits of bonk – the gratifying (albeit overshadowed) enhancements to our physical and mental health that come from the physical exertion itself as well as the biochemical cascade of everything from estrogen to testosterone, prolactin to oxytocin to beta-endorphins.

Before we proceed, let me offer the expected and requisite Primal caveat: I’m talking here about safe sex ideally with a committed partner. What good does it do to blow the overall health benefit by putting yourself at risk for the myriad of sexually transmitted diseases. Likewise, why negate the mental health boost by pursing sex in a relationship/liaison that isn’t emotionally healthy? ‘Nuff said?

Now for those long awaited advantages…. Let’s cut to the chase here, get to it, and jump right in. After all, there’s much to discuss and disseminate today. Lot of ins, lot of outs. (All right, I’ve had my fun….)

1. Improve Your Stress Response – And Your Blood Pressure

Sex certainly has the power to take the edge off. (Stress just kind of slides off….) The process of arousal and orgasm, of course, let loose a mesmeric elixir of natural pain killers and relaxers. What’s not to love? Though sex generally offers the most intense dose of aforementioned chemical cocktail, caresses of all kinds can impart generous benefits. (All the more reason to take your time and relish the full experience, I’d say.) Research has shown that a partner’s touch – whether curling up under the sheets or simply passing in the hall – initiates the release of oxytocin, which in turn can lower blood pressure and heart rate. The effect goes for so-called cardiovascular reactivity, the response of the cardiovascular system to stress. Participants who received comforting touch from their spouses before stressful events displayed lower blood pressure and lower heart rates. If that’s what a simple hug can do, imagine the inspiration you can give your partner the morning of a big presentation?

2. (While You’re At It…) Cut Your Risk for Cardiac-related Death

On a more dramatic note, the unique closeness of sex can have more consequential impact in the cardiovascular realm. In a 20-year long cohort study, researchers followed more than 900 men and found that having sex twice or more a week decreased a subject’s risk for a fatal heart attack – by more than 50%. That’s nothing to shake a stick at.

3. Upgrade Your Immune Function

An often cited study from Wilkes University suggests regular sex might offer a surge of immune potency. Among the 112 surveyed students, those who had sex 1-2 times a week showed a rousing 30 percent boost in salivary immunoglobulin. Those who had sex less frequently than once a week had a slight IgA edge over total abstainers. (In an interesting wrinkle, the “three or more times a week” crowd showed slightly lower IgA levels. To their possible chagrin, the researchers didn’t ask participants about the number of partners or other potential “relationship” factors that might have influenced the findings. Hmmm…lack of sleep?) Although it’s a study to take with a grain of salt, the basic premise is probably sound. As welcome as it is, the usual exchange of fluids (or the body’s anticipated exchange) represents contact with a foreign substance that likely contains some kind of microbial profile.

4. Get Some Pain Relief

Anyone who’s gotten jiggy with it when they’re sick knows sex can offer a temporary respite from their symptoms – especially when it comes to pain. (Kind of turns the proverbial headache excuse on its ear.) Both arousal and orgasm trigger the production of oxytocin, which then initiates a sensational rush of endorphins and corticosteroids – both fairly potent pain killers. Post coital bliss indeed.

In a study published in the Bulletin of Experimental Biology and Medicine, subjects who were given a dose of oxytocin saw their pain thresholds balloon by more than 50% during the course of the experiment. Seriously, who needs Advil for an analgesic?

5. Steady Your Cycle – and Possibly Increase Your Fertility

Physicians prescribe the birth control pill left and right to women who have irregular menstrual cycles. Regular sex might present a more enjoyable alternative for that particular purpose. Women who have sex with male partners once a week or more, research has shown, are more likely to experience consistent menstrual cycles and (as a result) have fewer fertility problems than women who had sex less often or abstained entirely. One possible reason? Male pheromones. Researchers from the Monell Chemical Senses Center and the University of Pennsylvania School of Medicine honed in on the pheromone link by applying men’s underarm secretions obtained to the upper lips of women subjects. (The image itself is kind of mood killer.) Whether absorbed or inhaled, the magic mix of aromatics in the male samples caused the women’s cycles to normalize toward a consistent 29 ½ day cycle.

Frequent sex with the same partner over several months or more can also “prime” a woman’s body for a healthy, full term pregnancy. Research at the University of Adelaide in South Australia showed that women who engaged in frequent sexual activity with their committed partners (including oral sex, which actually appeared more effective in the study) had higher rates of conception and fewer incidences of miscarriage, preeclampsia, and high blood pressure. Women’s bodies, the researchers suggest, literally learn and come to accept the particular proteins of their partners’ semen in a process called immune modulation. Having become accustomed to the familiar semen profile (oh, you again), the woman’s body is less likely to reject the fetus and placenta that result from conception with that partner.

6. Reduce Your Risk for Prostate Cancer

Research has linked frequent ejaculations (yes, the solo gig counts here) with a slightly lower risk for prostate cancer in later life. The golden frequency in this study? Twenty-one times per month. It’s a tall order, but I know you can do it.

One possible explanation for the decrease is the “flushing” theory. In its efforts to concentrate minerals and other necessary substances from the blood to make semen, the prostate can end up collecting a concentration of toxins as well. Releasing the semen – with said toxins – flushes the system of said impurities. (Gives a new meaning to cleaning out the pipes.)

7. Look Better

Now we’re getting to the good stuff. (Kidding.) Yes, there’s the ever flattering afterglow. It’s a shame they can’t bottle that. There’s so much more to gain, however, or maybe lose. How about calories for instance? Estimates vary but average around 85-100 calories per half an hour. Of course, real life expenditures diverge depending on how zesty an enterprise you enjoy. In terms of calories burned, you’re looking at low to moderate level activity, but your heart rate can easily climb to high intensity levels. It’s probably the most enjoyable cardio you’ll pursue any day of the week.

Then there’s the workout itself – a toning and stretching and strengthening that includes muscles you didn’t even know you had – ala that next morning ache. (Don’t forget about those less obvious – and all important – pelvic floor muscles, which support everything from orgasm intensity to urinary continence.) On the chemical front, intercourse offers a boost in testosterone for stronger bones and muscles. Finally, how about the appeal of a totally relaxed face and body – and the inevitable smile?

8. Finally… Feed Your Primal Self

I’m talking about more than your primal with a lowercase “p” appetite here. I mean your more inclusive, nuanced Primal (as in PB) self. As I’ve said many a time, living Primally isn’t an exercise in asceticism or deprivation. It’s about knowing and inhabiting your physical self more appreciatively, more pleasurably as well as responsibly. Sex isn’t just a procreative act. (Even in Grok’s day it served many more purposes than that.) Though technically unnecessary, it’s far from some isolated, tangentially relevant act. The desire and delight of sex is unique. It’s not an interchangeable element of our human experience. The shared intimacy and individual rapture teaches us, reveals to us, unfolds layers of our humanity, and lays bare a sensitivity and vulnerability, a vigor and power otherwise unknown to us. Even in its absence, sex helps define who we are and how we connect with life.

Not surprisingly, our sexual enjoyment extends far beyond the immediate physical crescendo. It has significance in our broader fulfillment. A cross-national study (PDF) revealed that both men’s and women’s sense of sexual well-being significantly correlated with their general life satisfaction.

When it comes to garnering all the good health benefits of sex, a lot of readers ask about frequency. As I mentioned in last week’s fitness post, your start racking up the health gains at once a week, but the composite of research suggests that two to three times will maximize overall advantages. Needless to say, it’s well worth working into the calendar.

Okay, the floor is officially open to discussion. I’ll be interested to see what comes of today’s post and its suggestions… Thanks for reading, and I hope you were inspired today. Have a great day (or night, as the case may be), everybody.

You want comments? We got comments:

Imagine you’re George Clooney. Take a moment to admire your grooming and wit. Okay, now imagine someone walks up to you and asks, “What’s your name?” You say, “I’m George Clooney.” Or maybe you say, “I’m the Clooninator!” You don’t say “I’m George of George Clooney Sells Movies Blog” and you certainly don’t say, “I’m Clooney Weight Loss Plan”. So while spam is technically meat, it ain’t anywhere near Primal. Please nickname yourself something your friends would call you.

  2. My Sir and I enjoyed this article after searching to find out if it was normal to have a sex life like ours. We have been madly in love for 16 years, and now in our early 30’s, our sex life couldn’t be better!! (average is 3 times a day..every day!) It has been 89 times since the beginning of 2013 and it is only Feb. 9th! I would only hope we are healthier after our fun-filled life!

  5. I love this site and find it so inspirational but this article made me sad. I’m eight years single and so sex is a distant memory. Such a shame when I agree it is such an integral part of what makes us human. And I’m only 35. However healthy I get I feel there is a big chunk of me missing without it.

    On a lighter note how many men do you reckon have leapt on the University of Adelaide study as an excuse to get more head. 😉

  7. I didn’t need more reasons to have sex, but it is nice to know that something that feels good is healthy at the same time.

  8. My husband could care less about any thing healthy including sex. Married 46 years and only had sex once in all these years. His whole life revolves around work and being left alone. He has lived his entire married life in our basement and myself upstairs. After the ‘I do’s” were done he lost all interest in me. He lives like a hippy , long gray hair, white beard old 60’s style clothes, no phone, computer, TV, or radio, has no friends and goes no where except work.
    It’s been stupid to stay with him, but I did and don’t really know why! Now I’m just tired and old and no where to go.

  12. At 23 years old, I’m a male who has never experienced intercourse. It’s been around 2-3 years since I’ve last kissed a girl, and have never been in a long-term or serious relationship. I’m not sure what’s wrong with me.

    People generally describe me as (not to “toot my own horn”) handsome, intelligent, talented, unique, even charming. So there doesn’t appear to be any defining reason as to why I’m lacking in this area of my life. I’m beginning to feel like I’m just not fit to breed, or that I have some kind of psychological defect…

    I long for a genuine relationship rather than promiscuity, but others tell me that in order to have a meaningful relationship I should be experienced in sex and dating first, even though this contradicts some of personal moral codes. Either way, I feel that something needs to change, because the lack of touch and affection from another human (female) seems to be doing some serious damage to my emotional and mental state.

    If anyone cares to shed some light on my situation or offer any advice it would be much appreciated. I am very concerned about my “dysfunction”.

    • I don’t think there is anything wrong with you. My brother also is around your age and still hasn’t had sex yet. He doesn’t seem bothered. He is so focused on school and getting his career started to be bothered by stupid girls his age (as he puts it) he is very picky with whom he dates. I ask him all the time. He just says girls his age act crazy, drink too much and act stupid. I think he just needs to find the right woman for him. Same for you. Nothing wrong with you at all. You may need to find the right person that you are attracted to both sexually and mentally. I’ve dated many men I found physically attractive and that we’re very nice. But didn’t have any desire to have sex with them even after the 4th date. Everyone is different! Be happy with who you are. Take the time to date different people and meet different personalities. Enjoy your 20s!!

  13. I had sex once 47 years ago on our wedding night. Husband hates me, sex and has no interest in anything so ugly and gross.

  14. Amy, planning to throw good years after bad? Any reason other than fear and inertia to stay with someone that feels that way about you? Because there are men who won’t feel that way and sure as heck won’t try to get you to feel that way about yourself. It’s hard to throw off something to which you’re long accustomed, but don’t you owe it to yourself?
