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.

Interactive Chart Tells You How Long It Takes to Get Frostbite

For many people, winter means dry skin and high heating bills. But if you find yourself outdoors in the right conditions, it can also mean frostbite. Frostbite occurs when the skin and the tissue beneath it freezes, causing pain, loss of sensation, or worse. It's easier to contract than you may think, even if you don't live in the Siberian tundra. To see if frostbite poses a threat where you live, check out this chart spotted by Digg.

The chart, developed by Pooja Gandhi and Adam Crahen using National Weather Service data, looks at three factors: wind speed, air temperature, and time spent outdoors. You can hover your cursor over data-points on the table to see how long you'd need to be exposed to certain wind chills for your skin tissue to freeze. If the wind chill is -22°F, for example (10°F air temperature with 5 mph winds), it would take 31 minutes of being outside before frostbite sets in. You can also look at the time scale above the chart to calculate it a different way. If you bring your cursor to the 40-minute mark, a window will tell that frostbite becomes a risk after exposure to -17°F wind chill for that amount of time. You can play with the interactive table at Tableau Public.

If you can't avoid being outside in extreme wind and cold, there are a few steps you can take to keep your skin protected. Wear lots of layers, including multiple socks, and wrap your face with a scarf or face mask before venturing into the cold. Also, remember to stay hydrated. According to the American Academy of Dermatology, drinking at least one glass of water before going outside decreases your risk of contracting frostbite.

Stop Your Snoring and Track Your Sleep With a Wi-Fi Smart Pillow

Everyone could use a better night's rest. The CDC says that only 66 percent of American adults get as much sleep as they should, so if you're spending plenty of time in bed but mostly tossing and turning (or trying to block out your partner's snores), it may be time to smarten up your sleep accessories. As TechCrunch reports, the ZEEQ Smart Pillow improves your sleeping schedule in a multitude of ways, whether you're looking to quiet your snores or need a soothing lullaby to rock you to sleep.

After a successful Kickstarter in 2016, the product is now on sale and ready to get you snoozing. If you're a snorer, the pillow has a microphone designed to listen to the sound of your snores and softly vibrate so that you shift positions to a quieter pose. Accelerometers in the pillow let the sleep tracker know how much you're moving around at night, allowing it to record your sleep stages. Then, you can hook the pillow up to your Amazon Echo or Google Home so that you can have your favorite smart assistant read out the pillow's analysis of your sleep quality and snoring levels the next morning.

The pillow is also equipped with eight different wireless speakers that turn it into an extra-personal musical experience. You can listen to soothing music while you fall asleep, either connecting the pillow to your Spotify or Apple Music account on your phone via Bluetooth or using the built-in relaxation programs. You can even use it to listen to podcasts without disturbing your partner. You can set a timer to turn the music off after a certain period so you don't wake up in the middle of the night still listening to Serial.

And when it's time to wake up, the pillow will analyze your movements to wake you during your lightest sleep stage, again keeping the noise of an alarm from disturbing your partner.

The downside? Suddenly your pillow is just another device with a battery that needs to charge. And forget about using it in a place without Wi-Fi.

The ZEEQ Smart Pillow currently costs $200.
