Do You Really Need Deodorant?

Some guys may  think their sweat doesn’t stink like everyone else’s, but ask their girlfriend or anyone near them in the gym and you’ll probably hear a different story.

The truth is, some people do give off fewer odors than others—but everybody has some sort of trace: “Body odor is determined by environmental factors, like what foods we eat, and genetics. Some people just smell stronger naturally,” explains Robyn Gmyrek, M.D., director of cosmetic dermatology at Columbia University Medical Center. But it’s not the actual dampness that smells. The bacterium that breaks your sweat down into organic compounds is what has that potent stench, she adds.

6 Reasons Women Fake Orgasms

In (uncomfortably relatable) sex news, researchers identified a whopping six different reasons that women fake orgasms, according to a pair of surveys of over 350 women, published in the Archives of Sexual Behavior. Even weirder (slash, more interesting): their reasons differ based on whether they're faking it during oral sex or penetration. Oh!

Chore Wars: How the Division of Domestic Duties Really Affects a Couple’s Sex Life

Are women less attracted to men who do more domestic chores? Or are men who share equally in the workload at home more appealing to a generation of stressed wives who are juggling family responsibilities and more work hours than ever?

It’s not a new debate, but it is one that has resurfaced recently thanks to a series of articles about stay-at-home fathers and a feature this month in the New York Times magazine by writer and psychotherapist Lori Gottlieb in which she suggests that that equality is turning us off. She writes: “In an attempt to become gender neutral, we may have become gender neutered.”

The Major Benefit of a Vegetarian Diet

Chock this up to one of the many reasons you should make an effort to eat more veggies: A vegetarian (or even flexitarian) diet may help lower your blood pressure, according to a new meta-analysis of more than a century’s worth of clinical trials and observational studies.

Researchers from various universities and medical facilities in Japan and the U.S. teamed up to pore over the vast amount of existing data on the relationship between a vegetarian diet and its effects on blood pressure. In addition to dietary info, researchers looked at study participants’ systolic and diastolic blood pressure readings—i.e., the ratio-like stat your doctor gives you at checkups, measured in millimeters of mercury. (A healthy BP is 120/80.)

Another Amazing Perk of Red Wine

Wine is packed with antioxidants. You know this and probably revel in it on the regular (as you should). Here's one more reason why: A new study in Cancer Cell International shows those antioxidants may block the growth of lung cancer—the most deadly type of cancer.

Researchers from Brock University and McMaster University in Ontario studied the effects of various types of wine—Cabernet Franc, Cabernet Sauvignon, Pinot Noir, and Riesling—on non-small cell lung cancer cells, the most common form of lung cancer.
