When Did Women Start Shaving Their Pits?

Earlier this week, Ethan Trex taught us the history of shaving. Several readers left comments inquiring about when women started shaving their legs and underarms, so we cracked open the mental_floss book In the Beginning: The Origins of Everything. Here's what we learned:

Underarms
American women had no need to shave their underarms before about 1915 "“ after all, who ever saw them? Even the word "underarm" was considered scandalous, what with it being so near certain other interesting body parts. Then came the sleeveless dress. An ad in the fashion mag Harper's Bazaar decreed that to wear it (and certainly to wear it while participating in "Modern Dancing"), women would need to first see to "the removal of objectionable hair." They didn't need much convincing, and by the early '20s, hairy underarms were so last decade, at least in America.

Legs

The '20s fashion was risqué on the bottom half, too, but most women of the era didn't seem to feel the need to shave their legs, and when hemlines dropped again in the '30s, the point became moot. The '40s, however, brought even shorter skirts, sheerer stockings, and the rise of leggy pin-ups such as Betty Grable. "The removal of objectionable hair" suddenly applied to a lot more surface area.

Naughty Bits
Was it porn actresses who started this one? GIs concerned about disease? The Brazilians? Nah. For hundreds of years, the bikini wax has been a common practice among a group more often associated with extreme modesty: Muslim women. In much of the Middle East and North Africa, brides-to-be remove all their body hair before the wedding night. Yes, all of it. Frequently, they stick with the aesthetic after marriage "“ and some men do likewise.

Beyond the Label: How to Pick the Right Medicines For Your Cold and Flu Symptoms

The average household spends an annual total of $338 on various over-the-counter medicines, with consumers making around 26 pharmacy runs each year, according to 2015 data from the Consumer Healthcare Products Association. To save cash and minimize effort (here's why you'd rather be sleeping), the Cleveland Clinic recommends avoiding certain cold and flu products, and selecting products containing specific active ingredients.

Since medicine labels can be confusing (lots of people likely can’t remember—let alone spell—words like cetirizine, benzocaine, or dextromethorphan), the famous hospital created an interactive infographic to help patients select the right product for them. Click on your symptom, and you’ll see ingredients that have been clinically proven to relieve runny or stuffy noses, fevers, aches, and coughs. Since every medicine is different, you’ll also receive safety tips regarding dosage levels, side effects, and the average duration of effectiveness.

Next time you get sick, keep an eye out for these suggested elements while comparing products at the pharmacy. In the meantime, a few pro tips: To avoid annoying side effects, steer clear of multi-symptom products if you think just one ingredient will do it for you. And while you’re at it, avoid nasal sprays with phenylephrine and cough syrups with guaifenesin, as experts say they may not actually work. Cold and flu season is always annoying—but it shouldn’t be expensive to boot.

Why You Might Not Want to Order Tea or Coffee On Your Next Flight

A cup of tea or coffee at 40,000 feet may sound like a great way to give yourself an extra energy boost during a tiring trip, but it might be healthier to nap away your fatigue—or at least wait until hitting ground to indulge in a caffeine fix. Because, in addition to being tepid and watery, plane brew could be teeming with germs and other harmful life forms, according to Business Insider.

Multiple studies and investigations have taken a closer look at airplane tap water, and the results aren’t pretty—or appetizing. In 2002, The Wall Street Journal conducted a study that looked at water samples taken from 14 different flights from 10 different airlines. Reporters discovered “a long list of microscopic life you don’t want to drink, from Salmonella and Staphylococcus to tiny insect eggs," they wrote.

And they added, "Worse, contamination was the rule, not the exception: Almost all of the bacteria levels were tens, sometimes hundreds, of times above U.S. government limits."

A 2004 study by the U.S. Environmental Protection Agency (EPA) found that water supplies on 15 percent of 327 national and international commercial aircrafts were contaminated to varying degrees [PDF]. This all led up to the 2011 Aircraft Drinking Water Rule, an EPA initiative to make airlines clean up. But in 2013, an NBC investigation found that at least one out of every 10 commercial U.S. airplanes still had issues with water contamination.

Find out how airplane water gets so gross, and why turning water into coffee or tea isn’t enough to kill residual germs by watching Business Insider’s video below.
