Scientists May Have Pinpointed How Much Exercise Your Heart Needs to Stay Healthy

There’s really no limit to the benefits of exercise, from cognitive improvement to increased cardiovascular capacity to more energy. But one of the biggest reasons to maintain a fitness regimen is to ward off chronic conditions. For example, exercise helps keep arteries from stiffening as we age, which lowers our risk of heart disease.

"Get some exercise," however, isn't exactly specific advice. Is twice a week good enough? Three times a week? Five? And for how long each time?

Researchers in Dallas, Texas may have found an answer. According to Newsweek, a study by staff at the Institute for Exercise and Environmental Medicine and area hospitals looked at 102 people, aged 60 and over, who self-identified as either sedentary, casual, committed, or master-level exercisers. They worked out anywhere from almost never to daily. The researchers found that casual exercise (two to three times weekly, 30 minutes each session) was associated with keeping the mid-sized arteries, like those found in the head and neck, from aging prematurely. But four to five sessions per week helped stabilize the larger central arteries, which send blood to the chest and abdomen. The research was published in the Journal of Physiology.

The study did not look at the type of exercise performed or other lifestyle choices that may have affected the participants' arterial health. But when it comes to moving your body to keep your arteries limber, it seems safe to say that more is better.

Move Over Dogs, Goats, and Peacocks: Llamas Are the Hot New Therapy Animal

Possibly because Dasher, Dancer, Prancer, and the rest of the reindeer are pretty busy at this time of year, Kimpton Hotel Monaco in Portland, Oregon, is offering guests the chance to hang out with a few jolly llamas instead.

The Washington Post reports that the friendly, festively dressed llamas belong to Mountain Peaks Therapy Llamas and Alpacas, which usually brings them to hospitals, rehabilitation centers, senior communities, hospice care, special-needs organizations, and even schools. According to the organization’s website, the visits help “alleviate loneliness, lower blood pressure, and reduce stress.”

And, though the clinical benefits to the Kimpton’s guests haven’t been proven, hotel manager Travis Williams confirms that everyone definitely loves spending time with the quirky quadrupeds. Last year, after overwhelmingly positive reactions to the llama visits, the hotel decided to bring them back.

“Once we saw the joy that it brought people, we just kept going,” Williams told The Washington Post.

While it might seem like the use of llamas for therapy is a characteristically Portland-ish idea, it’s not the only place you can find them. The New York Times reports that 20 llamas and alpacas are registered with Pet Partners, a national nonprofit organization for therapy animals, and many others are owned and trained by private family farms across the country.

Jeff and Carol Rutledge, for example, have 13 llamas and alpacas on their property in Stockdale, Texas, outside San Antonio. Three of them are registered therapy animals, having passed a test that includes being touched by strangers and staying unaffected while people argue near them.

During their visits to assisted living facilities, veterans’ homes, and other events in the area, the Rutledges have observed the animals having a profound effect on residents’ behavior. One man, who is nonverbal and recovering from a motorcycle accident, will murmur as he grooms one of the llamas. And the Rutledges’ high-school-aged daughter, Zoe, even did a science experiment for her 4-H club that showed the residents’ blood pressure is lower after visiting with the llamas.

While there’s not a very high chance of seeing therapy llamas in airports just yet, you might be lucky enough to see something a little smaller—like LiLou, San Francisco International Airport’s first therapy pig.

Nike Is Releasing a Durable Slip-On Sneaker Designed for Medical Professionals

Nike is known for releasing footwear that covers just about every activity under the moon—impact-absorbing running shoes, sleek soccer cleats, snazzy fashion statements, and so much more. Now, they’ve developed a sneaker for nurses, doctors, and other medical professionals who spend long shifts on their feet.

According to a press release, Nike sent designers to the OHSU Doernbecher Children’s Hospital in Portland, Oregon, where they learned from healthcare providers exactly what their jobs entail. Then, they used their findings to create the Nike Air Zoom Pulse, a “traditional clog made athletic.”

If you’ve ever gone sightseeing in a new city or even just taken a longer-than-expected afternoon stroll, you might have experienced firsthand that even your most comfortable walking shoes stop being so comfortable after a few miles of non-stop action—and nurses experience that type of exercise every time they go to work. During a regular 12-hour shift, a nurse might walk between four and five miles and sit for less than an hour. To account for that, the Nike Air Zoom Pulse features a full-rubber outsole, a flexible drop-in midsole, arch support, and a “heel fit so secure [that] it feels like a soft, snug hug.”

Since healthcare professionals also need a shoe durable enough to withstand spills of any kind, Nike coated the top of the Air Zoom Pulse with a polyurethane layer that’s easy to wipe down. It’s also a laceless slip-on, so people won’t have to worry about tripping on untied laces—and they’ll also be able to slip their shoes off for a quick nap in the staff room.

Six patients at the OHSU Doernbecher Children’s Hospital have contributed vibrant, colorful designs for the Air Zoom Pulse, which Nike will release for online orders (in versions that include its own colorways) starting December 7.
