The Science of Why You Shouldn't Eat at Your Desk

Where do you usually eat your lunch? If you work in an office, chances are you eat at your desk, slogging through your workload while trying not to get too much salad dressing on your keyboard in the process. Just one in five of us actually take any lunch break at all, and research suggests all this desk time is hurting our health and lowering our productivity.

“Staying inside, in the same location, is really detrimental to creative thinking,” Kimberly Elsbach, a professor at the University of California, Davis Graduate School of Management told NPR. “It's also detrimental to doing that rumination that's needed for ideas to percolate and gestate and allow a person to arrive at an 'aha' moment.”

A recent study put this anecdotal hypothesis to the test, asking participants to go for a 30-minute midday walk three times a week over a span of 10 weeks. The researchers equipped participants with a smartphone app that recorded their mood level, workload, tiredness, and motivation before and immediately after the walks. The results? The lunchtime strolls lowered employees’ stress levels and made them feel more enthusiastic about their work. A follow-up study showed these breaks also made participants feel more confident about their performance at work.

“Walking therefore seems to have both energizing and relaxing properties in the workplace,” says Cecilie Thøgersen-Ntoumani of Curtin University, who led the study.

So what’s going on here? What’s the secret of the lunchtime stroll? It turns out that just putting some space between you and your workload has a restorative effect on your brain. Previous studies have shown that employees who regularly take breaks during the workday are actually more productive than their workaholic counterparts. And physical exercise, even just a leisurely stroll around the block, tells the brain to produce stress-fighting chemicals called endorphins, which could help explain why walking made this study’s participants feel more relaxed.

Being outside enjoying nature comes with its own brain benefits. A dose of sunshine jumpstarts the production of serotonin, a neurotransmitter believed to be connected to mood and happiness. And green spaces like parks have a calming effect on our mental activity, moving us into a kind of meditative state which, researchers say, “is likely to have a restorative effect and help with attention fatigue and stress recovery.”

"We know that creativity and innovation happen when people change their environment, and especially when they expose themselves to a nature-like environment, to a natural environment," Elsbach says.

If you really can’t get out of the office, invest in a desk plant, which can serve as a mood-lifting substitute for actual outdoor foliage. And you don’t have to be outside to reap the productivity benefits of a lunchtime stroll, as research finds even walking around indoors can boost creativity some 60%. So the next time you’re feeling depleted, the least you can do is take a stroll down to accounting or tackle a few flights of stairs, and say no to the sad desk lunch. Your boss and your body will thank you.

Here's What You Need to Know Before Getting Inked or Pierced, According to Doctors

Getting inked or pierced is a rite of passage for many teens and young adults. But before getting that belly ring or butterfly on your back, experts want you to be aware of the risks, which are reviewed in a new clinical report from the American Academy of Pediatrics (AAP). According to NPR, it's the first set of recommendations the professional association has ever released on the practices.

Forthcoming in the October 2017 issue of Pediatrics and available online, the report provides a general assessment of the types and methods used to perform body modifications, along with potential health and social consequences. Here are a few main takeaways:

—It's unclear how often tattoos cause health complications, but they're generally believed to be rare, with the greatest risk being infection. One recent study found that nanoparticles in ink can travel to and linger in lymph nodes for an extended period. That said, you should check with your doctor to make sure all of your immunizations are up to date before getting either a tattoo or piercing, and that you're not taking any immunity-compromising medicines.

—Before shelling out your hard-earned cash on a tattoo, make sure it's something you'll likely still appreciate in five to 10 years, as it costs anywhere from $49 to $300 per square inch to remove a tattoo with lasers. (This might provide all the more incentive to opt for a small design instead of a full sleeve.)

—About half of people 18 to 29 years of age have some kind of piercing or tattoo, according to Dr. Cora Breuner, who is chair of the AAP committee on adolescence. Many individuals don't regret getting one, with some reporting that tattoos make them feel sexier. But while millennials appear to be cool with metal and ink, hiring managers might not be too pleased: In a 2014 survey of 2700 people, 76 percent said they thought a tattoo or piercing had hindered their chances of getting hired, and nearly 40 percent thought tattooed employees reflected poorly on their employers.

—Not all tattoo parlors are created equal, as each state has different regulations. Keep a close eye on whether your artist uses fresh disposable gloves, fresh needles, and unused ink poured into a new container. This helps prevent infection.

—The advice is similar for getting pierced: Make sure the piercer puts on new, disposable gloves and uses new equipment from a sterile container. Tongue piercings can cause tooth chippings, so be careful of that—and remove any piercings before you play contacts sports.

The Body
7 Essential Facts About the Pelvis

The human body is an amazing thing. For each one of us, it’s the most intimate object we know. And yet most of us don’t know enough about it: its features, functions, quirks, and mysteries. Our series The Body explores human anatomy, part by part. Think of it as a mini digital encyclopedia with a dose of wow.

The pelvis, which crooner Elvis was famous for thrusting around in ways that raised eyebrows, is not actually a single body part but a term that refers to a collection of bones, muscles and organs below the waist. We spoke to Katherine Gillogley, department chair of obstetrics and gynecology with Mercy Medical Group in Sacramento, California, for these seven facts about the pelvis.

1. SO WHAT IS THE PELVIS, EXACTLY?

"The pelvis refers to the lower abdominal area in both men and women," Gillogley says. "An important function of the pelvis region is to protect organs used for digestion and reproduction, though all its functions are crucial," she says. It protects the bladder, both large and small intestines, and male and female reproductive organs. Another key role is to support the hip joints.

2. THE PELVIC BONES FORM A BASIN.

Four bones come together to form a bowl-like shape, or basin: the two hip bones, the sacrum (the triangle-shaped bone at the low back) and the coccyx (also known as the tailbone).

3. YOUR PELVIC FLOOR IS LIKE A TRAMPOLINE.

At the bottom of the pelvis lies your pelvic floor. You don't have to worry about sweeping it, but you might want to do Kegel exercises to keep it strong. The pelvic floor is like a "mini-trampoline made of firm muscle," according the Continence Foundation of Australia. Just like a trampoline, the pelvic floor is flexible and can move up and down. It also creates a surface (floor) for the pelvic organs to lie upon: the bladder, uterus, and bowels. It has holes, too, for vagina, urethra, and anus to pass through.

4. IT PLAYS A KEY PART IN WALKING.

Anyone who has ever broken a pelvic bone or pulled a pelvic muscle will know just how key a role the pelvis plays in such functions as walking and standing. "The pelvis also acts as a solid foundation for the attachment of the spinal column and legs," says Gillogley.

5. THE FEMALE PELVIS STARTS OUT LARGER, BUT NARROWS OVER TIME.

Gillogley says that the female pelvis "tends to be larger and wider" than the male, most likely to accommodate a baby during pregnancy and to make childbirth possible. However, women's pelvises narrow as they age, suggesting that they start out wider to accommodate childbearing and then shift when that is no longer necessary. A shifting pelvis shape is thought to be a key part of our evolutionary history, as it changed as when we began walking upright.    

6. PREGNANCY CHANGES THE PELVIS FOREVER.

During pregnancy the body secretes a hormone known as relaxin to help the body accommodate the growing baby and soften the cervix. However, what happens is, "the joints between the pelvic bones actually loosen and slightly separate during pregnancy and childbirth," Gillogley says. Sometimes, however, relaxin can make the joints too loose, causing a painful syndrome known as symphysis pubis dysfunction (SPD), causing the pelvic joint to become unstable, causing pain and weakness in the pelvis, perineum and even upper thighs during walking and other activities. Many women with the condition have to wear a pelvic belt. It usually resolves after pregnancy is over, though physical therapy may be necessary.

7. IT'S ACCIDENT PRONE.

According to the American Association for the Surgery of Trauma, about 8 to 9 percent of blunt trauma includes pelvic injury, Gillogley says. "These accidents include falls, motor vehicle crashes, bicycle accidents, and pedestrians being struck by moving vehicles. With these serious injuries, pelvic bones can fracture or dislocate and sometimes bladder injury even occurs." So take care with your pelvis—in worse-case scenarios, breaks of the pelvic bones can require pins, rods, and surgery to fix.
