The “husbands” tag will lead you to several posts intended to help husbands be more attractive to their wives, including topics like clothes, muscles, hygiene, and improving her orgasms. Today I’m going to share a list of 19 ways for a man to be more attractive — according to science! I’m not going to talk about each one, because some of them are dumb or don’t apply in a marriage. Here it goes…

We’ve written about your wife’s indicators of interest before. A wife usually expresses her interest in sex more subtly than her husband, so don’t miss the cues!

“First the woman smiles at her admirer and lifts her eyebrows in a swift, jerky motion as she opens her eyes wide to gaze at him. Then she drops her eyelids, tilts her head down and to the side, and looks away. Frequently she also covers her face with her hands, giggling nervously as she retreats behind her palms.”

Grow a beard, it will make you look more dominant and aggressive.

In a 2013 study from researchers at the University of New South Wales, researchers had 177 heterosexual men and 351 heterosexual women look at images of 10 men in one of four conditions: clean-shaven, light stubble, heavy stubble, or full beard. Participants rated the men pictured on several traits, including attractiveness.

That women said the most attractive beard length was heavy stubble.

“Facial hair correlates not only with maturity and masculinity, but also with dominance and aggression,” write authors Barnaby J. Dixson and Robert C. Brooks.

“An intermediate level of beardedness is most attractive,” they add.

Build some muscle. Here the phrase “short-term relationships” basically means that the woman wants to bang.

In a 2007 study from University of California, Los Angeles, 286 women looked at pictures of shirtless men and indicated which ones seemed like they would make the best long- and short-term partners.

Results showed that women were more likely to want short-term relationships with the guys who had big muscles.

Wear strong colors, like red.

A 2010 cross-cultural study — with participants from China, England, Germany, and the US — found that women are most attracted to men wearing red.

In one experiment from the study, 55 female undergrads looked at a color photo of a man in either a red or green shirt, and then rated the man’s attractiveness.

Sure enough, the man was rated significantly more attractive when he was wearing a red shirt. The results were similar when researchers compared the red shirt to other color shirts as well.

Interestingly, participants generally weren’t aware that the man’s clothing color was influencing their perceptions of his attractiveness.

Be funny.

Multiple studies indicate that women are more attracted to men who can make them laugh. Interestingly though, men generally aren’t more attracted to women who can make them laugh.

Take “hunter-gatherer” risks.

A 2014 study led by researchers at the University of Alaska at Anchorage found that women are attracted to men who take what the researchers call “hunter-gatherer risks.”

More than 230 undergrads filled out questionnaires about how attractive they would find a partner who engaged in certain risky behaviors, as opposed to a partner who engaged in low- or no-risk behaviors.

Hunter-gatherer risks included mountain biking, deep-sea scuba diving, and extreme rollerblading. “Modern” risks included plagiarizing an academic paper, casually handling chemicals in a lab, and not updating the virus-protection software on your computer.

Low- and no-risk behaviors included biking along paved paths and carefully handling chemicals in a chemistry-lab class.

Results showed that women said they would be more attracted to men who engaged in hunter-gatherer risks — the kinds that were similar to risks faced by ancestral humans. Women said they would be less attracted to men who engaged in modern risks, which might seem just plain dumb.

Eat garlic!

In one study, eight men ate a slice of bread with cheese and 12 grams of fresh garlic; another eight ate bread and cheese without any garlic. For the next 12 hours, the men wore cotton pads under their armpits and were instructed not to use any deodorants or fragrances.

The following day, all the men returned to the lab, where 40 women sniffed the pads and rated the odor on pleasantness, attractiveness, masculinity, and intensity. Results showed that the garlic group was rated more pleasant and attractive and less masculine and intense.

And finally, looking proud is better than looking happy.

In one experiment included in the study, researchers had nearly 900 North American adults look at photos of opposite-sex individuals online.

The researchers were specifically comparing people’s perceptions of expressions of pride, happiness, shame, and neutrality (other people had already identified the emotion behind the expression in the photo). For women evaluating men, the most appealing expression was pride, and the least appealing was happiness.

It’s important to note that the features and behaviors listed above generally do not make a woman more attractive to a man. We’re very different creatures.

We’ve written a lot about how good sex is for your health, so it shouldn’t surprise you that sex is also helpful for reducing the risk and impact of atherosclerosis (the build up of fatty deposits in the arteries that can lead to heart disease and stroke).

According to von Borstel, exerting yourself between the sheets is one of the most beneficial exercises you can do for your heart. “As well as an entire cardiac workout, before and during intercourse there is a big release of hormones that have a protective effect on our cardiovascular system,” he explains.

An orgasm can release 50 different chemical messengers. One substance, oxytocin, the so-called cuddle hormone, triggered by affectionate physical contact, is proven to lower blood pressure, promote the healing of wounds and reduce stress.

Endorphin is another useful hormone released during sex – this helps to lower heart rate and blood pressure to the heart muscle during exercise. Meanwhile, both oestrogen, which is anti-inflammatory, and testosterone, which lowers cholesterol levels in the blood, receive a boost through sex, too. High cholesterol causes fatty deposits in blood vessels to attach to artery walls, causing clogging and arteriosclerosis, says von Borstel, who recommends having “as much loving sex as possible”.

As for garlic, it’s obviously the king of seasonings, but did you know that it’s neither a spice nor an herb? It’s technically an aromatic vegetable like its relation the onion — and a member of the lily family. Lilies? Where have we read about those before?

Song of Solomon 2:1-2

She

I am a rose of Sharon,
    a lily of the valleys.

He

Like a lily among thorns
    is my darling among the young women.

If wood is the ancient metaphor for the penis, the equivalent image for the female is the flower. The Lover’s member is a massive cedar, and his Beloved’s girly bits are a beautiful lily — compared to her, the other young women are thorns and thistles.

Eat up! (Although I grant that “lily” is a more appealing metaphor than “garlic” when it comes to a wife’s intimate parts.)

In addition to tasting great, eating garlic (and onions) can help promote the health of your circulatory system.

“Vegetables and fruits have secondary phytochemicals that have the same effect as different [heart protective] medications but not in a dose that is dangerous for your body,” says von Borstel. He cites ginger, onions and garlic as blood thinners which promote blood flow through vessels and improved blood supply to organ and tissues, and recommends grating a teaspoon of root ginger or two or three teaspoons of grated garlic into a glass of water a day to naturally reduce blood pressure.

“As long as you eat in a balanced way, it is no problem to eat these every day,” he says. Allicin, the key ingredient found in garlic and onions, is thought to act on the kidneys, changing levels of hormones and dilating the blood vessels. Research by the Institute of Food Research found that eating a 100g to 200g serving of onions (one to two onions) had the biggest impact on inflammation.

Eating a “lily” probably wouldn’t hurt either! Can anyone suggest a new heart-healthy bifecta that brings together sex and garlic in a fun and exciting way?
