The eye’s limbal ring falls into the category of something that's overlooked but not unseen. It’s the dark circle around the iris that enhances the whiteness and brightness of the sclera (the whites of the eyes). Researchers at the University of California at Irvine asked people to rate sets of faces that were identical except for the eyes -- one had dark and distinct limbal rings and the other had none. The outcome? Whether male or female, the faces with prominent limbal rings were considered more attractive. The likely reason is that a dark, well-defined ring is a signal of youth and health -- qualities that people seek in mates. It’s thickest and most prominent through the early 20s and fades -- often becoming nonexistent -- with age and medical conditions.
Women Use Pick-Up Lines, Too
Women are pickier than men, right? Not true, says a speed-dating study at Northwestern University. When men remained seated and women rotated around the room, approaching a new man at every table, the women acted more like guys -- that is, they appeared to have lower standards. Regardless of gender, whoever makes the first move is less picky than the people they target, the researchers found. When we invest an effort, we’re more “into” the people we hit on than we’d be if they approached us first.
In an hour at a singles bar, average-looking women could be approached by up to four men, found Monica Moore in her study at the University of Missouri. What were these sirens doing? Making more than 35 body-language gestures -- smiles with eyebrows raised; short, darting glances; arm flexes; hair flicks; neck caresses and other “displays.” Meanwhile, Moore found that a beauty who sits there doing nothing is unlikely to be approached at all. Only when a woman’s body language expresses some interest do men feel comfortable making a move.
Your signature scent -- whether it’s Chanel, Shalimar, or patchouli -- becomes you. Literally. Fragrances may amplify and advertise your unique genetic makeup to potential partners, finds a study at the Max Planck Institute in Germany. People who share the same variants of immune system (MHC) genes often preferred the same scents (rose oil, musk, or vanilla, for instance). This suggests that particular scents work best with particular body chemistries -- and that we know intuitively what fragrances smell best on us. Indeed, a recent Czech study found that when volunteers’ sweat was mixed was their preferred perfume (versus a random one), impartial noses gave the resulting mélange much higher ratings.
You Ate Garlic Bread On Your First Date
Here’s another olfactory surprise: Garlic may make you smell more attractive. Researchers in the Czech Republic asked people to eat garlic cream cheese (the equivalent of two to four cloves) every day for one week, while wearing scent-trapping pads in their armpits. The next week, the same volunteers ate their bread with plain cream cheese. Which sweat smelled more attractive, more pleasant, and less intense to female judges -- garlic or plain? Garlic, naturally, but why? Garlic contains antioxidants and improve metabolic functioning, the researchers say, which may improve your body odor. Plus, garlic’s antibacterial properties help to kill the real culprit: foul-smelling underarm microorganisms.
You Had Chemistry On Top Of Chemistry
We all know oral contraceptives are useful -- for reducing flow, cramps, and preventing unplanned pregnancies. The surprise is that the Pill may also lead to unintended romantic quandaries. A U.K. study found that women who were on oral contraceptives when they met their partners were, years later, likelier than non-users to be turned-off, sexually dissatisfied, and eager to fantasize about an affair. But here’s the interesting part: They were also generally more satisfied with their partner’s (non-sexual) contributions, and therefore less likely to separate. The researchers explain: Under Pill-driven conditions of high-progesterone and low fertility, women go for relationship-worthy qualities such as wealth and intelligence more than high-testosterone traits (biceps and block jaws) that are associated with flings. Oral contraceptives may also lead women to reverse their usual preferences in male body odor. Once a woman goes off the Pill, her other instincts complicate the relationship.
Betty Boop Came Out At 'Hi'
Whether she’s aware of it or not, the pitch of a woman’s voice increases a notch (becoming higher but not shrill) when she’s flirting, finds a study at McMaster University in Canada. Conveniently, men much prefer these high-pitched dulcet tones over deeper ones. A woman can strike her highest chords around ovulation, when she’s likeliest to conceive. Another coincidence: This happens to be the time of month that men give female voices the highest attractiveness ratings.
