Hitting the Slopes? Here’s How to Have Fun and Stay Safe

FRIDAY, Jan. 1, 2016 (HealthDay News) — Many families and outdoor enthusiasts hit the slopes this time of year. Skiing and snowboarding are fun for people of all ages, but you need to know how to keep yourself and others safe on crowded mountains, according to Nemours Health.

Having the right clothes and equipment can protect skiers and snowboarders from low temperatures and injuries. In addition to warm clothing, proper boots, poles, goggles and a helmet specifically designed for skiing or snowboarding are essential.

Every time you head up a mountain, this is what you need:

  • Skis: Larger skis are typically harder to control. Buy or rent skis that are the appropriate size for your height and skiing ability. Have your skis fitted and tuned by a trained professional.
  • Bindings: Bindings hold your boots to your skis or snowboard. They should be able to release if you fall to prevent serious injuries. Bindings that release too easily, however, can also be dangerous. Have your bindings adjusted by a pro.
  • Boots: Make sure your boots fit correctly. Your feet should always be comfortable and warm. This will help you control your skis or snowboard. Boots should always be buckled securely to properly support your feet and ankles.
  • Poles: Skiers should make sure their poles are the right length and have looped straps that go around wrists.
  • Helmet: Wearing a helmet every time you ski or snowboard is the most important way to prevent a life-threatening injury. Be sure your helmet fits properly and always fasten the chin strap securely. Ski and snowboarding helmets have special ventilation for warm days and a place to attach goggles. Don’t wear a football or biking helmet for skiing or snowboarding.
  • Goggles and sunglasses: The sun’s rays are stronger at the top of a mountain than at sea level. They can also reflect off the white snow, increasing your risk for exposure to harmful UV rays. Sunglasses are the best way to protect your eyes from the sun’s rays, but goggles can protect against the sun as well as cold, snow, tree branches and other hazards.
  • Gloves or mittens: It’s important to wear gloves or mittens while skiing and snowboarding. Some gloves also provide a pocket for hand warmers. In very cold conditions, mittens may offer greater warmth than gloves.

5 Tips to Help Make New Year’s Resolutions Stick

FRIDAY, Jan. 1, 2016 (HealthDay News) — New Year’s resolutions are more easily made than kept, but there are ways to turn them into lifelong habits, a psychologist says.

“Everyone is motivated when they first decide to make a New Year’s resolution,” Josh Klapow, a clinical psychologist at the University of Alabama at Birmingham, said in a university news release. “The problem is that you can ride the wave of motivation for only a short while. If you want to stick with your resolution, you’d better make it a habit.”

Klapow advises those making New Year’s resolutions to follow the “S.M.A.R.T.” system, which includes the following five steps:

  • Set specific goals. The more specific the resolutions, the more likely they will be followed. Rather than make general promises to eat better or exercise more, make a resolution to eat five servings of fruits and vegetables daily or walk 30 minutes each day.
  • Monitor your actions. Keep track of your goals and monitor your progress. If you’ve resolved to exercise more, mark each workout on your calendar in a visible place in your home.
  • Arrange for success. For you to meet your goals, you need to eliminate any barriers preventing you from reaching them. If you want to eat less sugar, remove sweet treats from your home. If you want to make it to the gym every morning, place a packed gym bag by your door so it’s ready to go.
  • Recruit a support team. You’re more likely to stick to your resolutions if you have the support of others. Let your friends and family members know about your plans, so they can help you attain your goals. If you want to exercise more, a workout partner can also help you stay on track.
  • Treat yourself. Reward yourself for sticking to your resolutions. Once they’ve become a habit, enjoy a movie, fun outing or a healthy treat to allow you to feel good about your success.

9 Paleo Snacks You Can Eat on the Go

If you’re eating Paleo, then you’ve taken a pass on most packaged snacks, which tend to be full of Paleo no-nos like sugar and artificial ingredients. (And if you’re still not clear on what it means to eat Paleo, here’s everything you need to know about this diet.) So what’s a primal person supposed to gnaw on between meals—especially when they can’t be home to prep something from scratch? Read on for delicious bites to keep the munchies at bay.

Meat:

The New Primal Meat Sticks ($40 for 20; thenewprimal.com)

Remember those scary gas-station mystery-meat sticks? (Or is it just us?) Here’s a decidedly grown-up, much cleaner version made with pastured, grass-fed beef flavored with honey, lemon peel, salt and spices. It has all the primal satisfaction of chewing on a well-seasoned beefy stick, and the convenience of easy-to-toss-in-a-purse packaging, but without the mile-long ingredient list. Plus, it has a respectable 90 calories, 6g fat and 200mg sodium (and 6g protein to keep you going until your next mealtime).

RELATED: 17 High-Protein Snack Ideas

Field Trip Jerky ($6 for 2.2 oz.; amazon.com)

If you like jerky but are avoiding excess salt, you’ve come to the right place. Field Trip relies on a mix of spices and not a ton of sodium, and doesn’t over-season its jerky. So the result is a tasty, really enjoyable, satisfyingly beefy jerky that won’t leave you gasping for your water bottle. (Note: They have turkey jerky, too, if you prefer.) Also, notably, they use wheat-free soy sauce, so it’s gluten free. It’s also nitrite- and preservative-free.

field-trip-jerkey

Epic Coconut Carnivore trail mix ($5 for a 2-oz. package; amazon.com)

Jerky is a Paleo mainstay, but it can sometimes feel a bit one-note chewing away on dried meat after a while. Enter Epic with its trail mixes, innovative pouches that have a bit of jerky on one side, and a bit of trail mix on the other, so it’s more of a party for your taste buds. Our fave: The Coconut Carnivore (264 calories, 18g fat and 380mg sodium), which has grass-fed beef jerky and toasted organic coconut. It doesn’t get much more Paleo than that.

Bars:

RX Bar ($19 for 12 bars; amazon.com)

You gotta love a bar that has so few ingredients, and such straightforward ones, that it lists them on the front of the package… in large type. RX Bars do just that. Though they come in several flavors (and obviously the Peanut Butter wouldn’t qualify as Paleo), our fave is the Blueberry. Made with egg whites, almonds, cashews, dates and, of course, blueberries, it really brings the berry flavor. Plus it’s soft and chewy, not chalky like some protein bars (though it packs 12g, for 210 calories, 9g fat and 11gmg sodium).
rxbar

Exo Bar ($35 for 12 bars; amazon.com)

So, OK, yeah, these are the bars made with cricket flour. As in, flour made from ground-up crickets. But they also have almonds, dates, prunes, coconut and cocoa, so you get a satisfying, chocolate-y bar (with 260 calories, 15g fat and 45mg sodium, plus 10g protein and 8g fiber). Our brave taster noted, “If you can handle the idea that there’s ground up crickets in there, you will be fine. Some people are just grossed out by the thought, but you really can’t tell when you eat it. Also: Is it really more gross to eat ground up crickets than it is to eat say, a hot dog?” Fair enough.

Simple Squares ($26 for 12 bars; amazon.com)

Bars can be a mixed bag texture-wise, with some in the soft-and-smooth category, others leaning toward hard and chalky. If you love a grainy granola bar, you’ll really enjoy these. Though they’re grain-free, they have a soft, grainy texture, somewhere between a soft granola bar and an oatmeal cookie. Of all the interesting flavors (Sage! Chili Pep!), we enjoyed Coffee the most. All of the bars have a nutty, coconutty, honey flavor, and the addition of ground organic coffee beans really wakes these up (sorry).

simple-squares

Other:

Artisana Raw Coconut Butter squeeze packs ($17.50 for 10, amazon.com)

If you’re a primal eater, no doubt you’ve already discovered the wonders of coconut butter. This creamy, rich spread, made from pureed coconut meat, makes luscious Paleo desserts, bulks up smoothies, turns plain sliced bananas or apples into tropical treats. It isn’t practical to lug around a whole jar of the stuff, but luckily Artisana makes these convenient squeeze packs, perfect for school bags, purses, briefcases, carry-on bags, etc. With 197 calories, 20g fat and only 9mg sodium, you can eat one with abandon.

artisina

Go Raw Zesty Pizza Sprouted Flax Snax ($31 for 6 packs; amazon.com)

Admit it: Even if you’re the most dedicated primal eater ever, you miss pizza. And chips. (Come on, of course you do.) Good news: These wholesome, flavorful bites go a long way toward satisfying not only your need for crunch, but also that hankering for pizza. Since they’re made from sprouted flax, sunflower and sesame seeds as well as tomato and spices, you can chomp away to your heart’s content (an ounce has 180 calories, 13g fat and 290mg sodium – plus, find another chip that has 8 percent of your day’s iron and 5g each of protein and fiber).

go-raw-zesty-pizza

Tiger Nuts ($6 for a 5-oz. bag; amazon.com)

These odd, chewy little bites may be new to the scene but certainly not to humanity; apparently they’ve been cultivated for the last 4,000 years. They are, in fact, not nuts, but small tubers, eaten raw. OK, that doesn’t sound delicious, and they’re definitely an acquired taste—but once you get into these little things, they’re kind of addictive; very chewy, slightly sweet, kind of chestnut-like. An ounce has just 120 calories, 7g fat and no sodium, but also packs in 10g fiber and 10 percent of your day’s iron. All that chewing means you don’t wolf them down and reach for something else, too.

Need to Boost Your Memory? Then Get Your Zzzz’s

THURSDAY, Dec. 31, 2015 (HealthDay News) — A good night’s sleep can help you remember new faces and names, researchers report.

The researchers showed 20 photos of faces with matching names to 14 volunteers in their 20s. Twelve hours later, participants were shown the photos again and asked if the faces and names matched.

The test was done twice — once after the participants had slept for up to eight hours and once with a period of regular day activities in between. After sleeping, the participants correctly matched 12 percent more of the faces and names.

How long or how deeply volunteers slept did not influence their ability to match faces and names. But, more research is needed to find out if these factors are important, according to the authors of the study published recently in the journal Neurobiology of Learning and Memory.

“We know that many different kinds of memories are improved with sleep. While a couple of studies have looked at how naps might affect our ability to learn new faces and names, no previous studies have looked at the impact of a full night of sleep in between learning and being tested,” corresponding author Jeanne Duffy said in a news release from Brigham and Women’s Hospital in Boston. Duffy is an associate neuroscientist in the hospital’s division of sleep and circadian disorders.

“We found that when participants were given the opportunity to have a full night’s sleep, their ability to correctly identify the name associated with a face — and their confidence in their answers — significantly improved,” she said.

The findings suggest that getting a good night’s sleep after learning new things may help people retain more of that new information, according to the researchers. This study looked at young adults, but the authors want to conduct similar studies in people of all ages, including older adults.

“Sleep is important for learning new information. As people get older, they are more likely to develop sleep disruptions and sleep disorders, which may in turn cause memory issues,” Duffy said. “By addressing issues with sleep, we may be able to affect people’s ability to learn things at all different ages.”

Researchers ID Areas of Western U.S. With Risk of Plague

THURSDAY, Dec. 31, 2015 (HealthDay News) — Parts of central Colorado, north-central New Mexico and southwestern and northeastern California have the highest risk for human exposure to plague, new research suggests.

The scientists said their findings, which are based on cases of plague reported in both wild and domestic animals between 2000 and 2015, could help public health officials better monitor the infection, which can be deadly in humans.

In recent years, seven human plague cases have been reported, on average, each year, affecting people of all ages. Half of reported cases involved people between the ages of 12 and 45, according to the U.S. Centers for Disease Control and Prevention.

“The findings can be used by public health agencies to target specific areas for enhanced plague surveillance within areas and counties predicted to be at high risk, as well as by other research teams to direct the sampling of local wildlife populations for the identification of Yersinia pestis in wild animals that find themselves in close proximity to humans and human developed landscapes,” said researcher Michael Walsh. An assistant professor of epidemiology and biostatistics with the School of Public Health at SUNY Downstate in New York, his comments appeared in a university news release.

Plague was introduced into the United States in 1900, according to the CDC. Rat-infested steamships sailing from affected areas brought the disease, which is caused by Yersinia pestis bacteria found in rodents and their fleas.

The last urban plague epidemic in the United States occurred in Los Angeles in 1924 and 1925. After that outbreak, plague spread from urban rats to rural rodent species. This caused plague to become entrenched in many areas of the western United States. Most human cases have been reported in rural areas of northern New Mexico, northern Arizona and southern Colorado; and in California, southern Oregon and far western Nevada, the researchers said.

The transmission of plague from animals to people is less common than it was a century ago. But, those living in the western United States are still at risk for the disease, according to the study published recently in the journal PeerJ.

The researchers pinpointed the regions at high risk for human exposure to plague using a formula that took several factors into account. Factors included climate, altitude, land cover and the presence of a rodent known as the North American deermouse (Peromyscus maniculatus), which is known to carry the disease.

Families of Critically Ill Patients Need Extra Support, Too

THURSDAY, Dec. 31, 2015 (HealthDay News) — When a loved one is admitted to a hospital intensive care unit (ICU), family members need support, too.

“Families are totally unprepared for a sudden injury and overwhelmed when it is a very serious injury. Families need a road map to guide them through their worst moments, and that is my job,” said Kelly McElligott, a clinical social worker in the burn center at Loyola University Health System in Maywood, Ill.

Each year, roughly 2.1 million patients are transferred from an emergency room to an intensive care unit, according to the U.S. Centers for Disease Control and Prevention.

McElligott described several ways people can deal with the sudden hospitalization of a critically ill loved one, including:

  • Take care of yourself. “If you do not take care of yourself, you cannot take care of someone else,” she said. “Many family members, especially parents, feel they need to be at the hospital 24/7 with their loved one. Everyone needs to take time to eat, sleep, exercise and be with other people in the outside world.”
  • Continue to live. “Life does not stop because someone is in the hospital. Other family members need attention and support also,” McElligott said in a Loyola news release. “Mom and Dad need to be role models more than ever at this time. The hospital team can help support and guide them. And they can feel strengthened and confident to continue to guide their families.”
  • Let others help. “Friends, relatives, colleagues and others will offer assistance and it is critical to accept help. For example, coming home to a clean house and a meal in the refrigerator is very convenient and also comforting,” McElligott said. “Usually there are outgoing neighbors or colleagues who will serve as primary contacts to relieve the burden. People feel better when they have something to do; let them help and everyone will benefit.” Online programs, including those that coordinate meals, errands and communication with family members, can also help.
  • Ask questions. “No individual could know what to expect when a severe injury occurs,” McElligott said. “That’s what medical professionals are for.” Write down questions or concerns as they occur to you, and take notes while meeting with doctors or other health professionals. “The more you know, the less you will fear.”
  • Be open about your experience. “Reach out to people for support by sharing your experience or what you have witnessed. Often, this will help reduce anxiety and build confidence,” McElligott said. “Getting feedback from others also can be reassuring and supportive.”
  • Find peer support. Others who have had similar experiences can help people understand that it’s still possible to laugh, socialize and enjoy life. “People are very resilient,” McElligott said. “The transformations that happen once the shock wears off are amazing.”

4 Ways Your Workout Should Change After You Turn 40

There’s no getting around biology: with the passage of time, we all become a little stiffer, squishier, wobblier. But that said, the 40-something you can be as strong as ever. This is the message behind Fitness After 40 ($19; amazon.com), a practical guide by orthopedic surgeon and mobility specialist Vonda Wright, MD. The trick, she says, is exercising smarter. Below we’ve pulled four tips from the pages of her book that every active woman should take to heart.

RELATED: 20 Health Mistakes You Need to Stop Making Before You Turn 40

Work on your flexibility every day

 As we age, our tendons and muscles tend to get tighter, and our risk of injury—tendinitis, in particular—goes up, says Dr. Wright, who directs the Performance and Research Initiative for Masters Athletes at the University of Pittsburgh Medical Center. She compares stiff connective tissues to dried-out rubber bands. One hard tug and the brittle material tears apart. This is why you need to stretch daily, she says.

One of her favorite techniques: foam rolling. “Essentially the log of hard foam serves as a rolling pin to break up small adhesions and scar tissues, thereby increasing blood flow to problem areas,” she writes in her book. “Foam rolling first thing in the morning (after a hot shower) leaves you limber for the rest of the day.”

Dr. Wright is also a big believer in dynamic stretching and warm-ups, which involve slow, controlled movements (like shoulder rolls and sumo squats) rather than static stretches (the grab-your-ankle-and-hold-for-30-seconds kind).

“Flexibility is so easy to ignore,” she writes, but it’s essential if you want to stay active. Mornings too crazy for yet another task? Stretch on your lunch break, she suggests, or in the evening while you watch TV.

Use your muscles—or you’ll lose ’em

It’s sad but true. Between your 25th birthday and your 50th, you could lose up to 10% of your muscle mass, Dr. Wright explains. Then over the next 30 years, you could lose another 45%. And it gets worse: Lost muscle is typically replaced by fat. “This fat makes us bigger all around because a pound of fat takes up 18% more room on our frame than a pound of fat,” she writes.

But it doesn’t have to be that way! You can prevent muscle loss by using your muscles. As the years go by, strength training becomes increasingly important, she says. Although by “strength training,” Dr. Wright doesn’t mean what you might think….

Step away from the weight machines

“Most of us grew up in an era when ‘strengthening our quadriceps’ meant sitting on a leg press machine and pushing a sled of weight up a slope,” Dr. Wright says in the book. But have you ever pushed a sled uphill with your legs in real life? Probably not.

She wants you to train your muscles the way you actually use them—and build what’s called functional strength. For example, in real life you use your quads in coordination with your hamstrings, butt and core to pick up kids, climb stairs, and load Ikea furniture in the car. So skip the leg press and do squats and lunges instead. (For more functional moves, check out this circuit from celebrity trainer Juliet Kaska.)

Work balance exercises into your regular routine

Stand on one leg like a stork. Really, give it a try right now… Tougher than you expected? We often don’t realize our balance is going until we’re toppling over, says Dr. Wright. Part of the problem is that with age, the neuromuscular connections that help keep us upright slowly decline. But the good news? Those nerve pathways “can be entirely reclaimed by specific daily attention,” Dr. Wright assures. She suggests taking up tai chi, Pilates, or yoga, all of which can improve stability; or adding balance moves (like side leg raises and toe raises) to your usual workout. And every day, practice that stork impersonation while you brush your teeth.

Can You Really Be Allergic to Wi-Fi?

allergy-wifi

I’ve read that people claim to be allergic to Wi-Fi. Is this a real thing?

The answer is still up for debate, but the World Health Organization did acknowledge this phenomenon—referred to as electromagnetic hypersensitivity (EHS)—many years ago. It’s described as the physical reactions (including heart palpitations, fatigue and nausea) some people claim to have when they’re exposed to electromagnetic radiation, emitted by devices such as cell phones and computers, as well as wireless Internet routers. However, many doctors and experts are still far from convinced that it’s a valid health concern.

RELATED: 6 Ways Your Mobile Devices Are Hurting Your Body

It’s true that people who are worried that they’re suffering from EHS experience real discomfort. But the symptoms that are typically associated with EHS are nonspecific, and there’s been scant evidence linking them directly to electromagnetic field exposure. Some research suggests that the physical complaints may be caused by fear and anxiety about having this condition—not the actual radiation.

RELATED: 14 Reasons You’re Always Tired

If you’re concerned that something within your home or work environment might be behind a reaction you’re having, you should always ask your doctor about it. But until we have more long-term scientific study to back up the diagnosis of EHS, I wouldn’t chuck your smartphone out the window just yet.

Asthma May Be Linked to Shingles Risk

THURSDAY, Dec. 31, 2015 (HealthDay News) — People who suffer from asthma may be more likely to develop the painful skin condition known as shingles, a new study suggests.

The finding builds on previous research that suggested a link between childhood asthma and shingles risk.

“Asthma represents one of the five most burdensome chronic diseases in the U.S., affecting up to 17 percent of the population,” said study author Dr. Young Juhn, a general academic pediatrician and asthma epidemiologist at the Mayo Clinic Children’s Research Center in Rochester, Minn.

“The effect of asthma on the risk of infection or immune dysfunction might very well go beyond the airways,” Juhn said in a Mayo news release.

The researchers analyzed the medical records of patients with suspected cases of shingles. They identified 371 people (average age 67) with the condition. Those patients were compared to 742 people who didn’t have shingles.

Of the 371 shingles cases, 23 percent of the patients had asthma. However, just 15 percent of the people who didn’t have shingles had asthma, the researchers found. People with asthma had a roughly 70 percent higher risk for shingles than people without asthma, the researchers reported in the Dec. 28 issue of the Journal of Allergy and Clinical Immunology.

However, the study did not prove a cause-and-effect relationship between asthma and shingles.

Eczema, or atopic dermatitis, was also associated with a higher risk of shingles. Shingles occurred at a rate of 12 percent in patients with eczema, compared to 8 percent of those in the control group, the researchers said.

It’s unclear why asthma and eczema might be linked to an increased risk for shingles. But, the researchers suggested that asthma might help trigger the reactivation of the virus that causes shingles.

“As asthma is an unrecognized risk factor for zoster [shingles] in adults, consideration should be given to immunizing adults aged 50 years and older with asthma or atopic dermatitis as a target group for zoster [shingles] vaccination,” Juhn said.

Since 2006, there has been a shingles vaccine available in the United States that lowers the risk of shingles by about 50 percent. The U.S. Centers for Disease Control and Prevention recommends all adults get the vaccine when they reach the age of 60.

Shingles affects nearly 1 million Americans every year, according to the study authors. The condition is particularly prevalent among older adults.

Could Football Practices Without Helmets Help Prevent Concussions?

By Randy Dotinga
HealthDay Reporter

THURSDAY, Dec. 31, 2015 (HealthDay News) — A new strategy to prevent concussions on the football field that seems counterintuitive may actually work, a new study suggests.

Instead of shielding the head with increasing layers of padding, researchers think they can reduce head impacts by having players temporarily practice without helmets. That approach seems to encourage players to avoid using their heads as weapons, the researchers added.

“We’ve found a way to decrease the number of impacts in the sport of football,” said study author Erik Swartz, chair of kinesiology at the University of New Hampshire. “It’s natural. By doing these drills without helmets, we take advantage of their [players’] vulnerability when their heads aren’t protected. They’ll naturally keep their heads out of contact.”

The new study into this strategy is tiny and has its limitations, an expert pointed out. And, due to its design, the study can’t prove that more helmet-less practice time reduces head impacts over a season. More research is necessary to know whether helmet-less practices can really help protect football players in general, let alone whether it’s appropriate for various levels — from flag football for kids to the professionals in the National Football League.

The study appears in the January issue of the Journal of Athletic Training.

Concussions in sports have garnered increasing attention recently. The focus has come amid greater awareness about devastating and even deadly head injuries to football players at all levels.

The new Will Smith movie, Concussion, deals with the dangers of football-related head injuries in pro football.

As helmets have become more sophisticated, researchers like Swartz fear players feel free to take more risks because they believe they’re protected against injury.

“It provides a false sense of security,” he said. “You can sustain a lighter magnitude impact for multiple times, and it doesn’t hurt. So you’re less careful with your head when it’s protected.”

In the new study, researchers randomly split 50 National Collegiate Athletic Association (NCAA) Division 1 football players from the University of New Hampshire into two groups of 25. One group practiced as normal with helmets, while the other spent five minutes once or twice a week doing tackling drills without helmets or shoulder pads.

Researchers studied data from sensors the players wore on their skin. The study revealed that those who went through the helmet-less practices had 30 percent fewer head impacts over the season compared to those who practiced with helmets. Overall, those who took part in the helmet-less program had about 10 impacts, while the others had about 14, the study authors said.

Swartz believes that players who practice without helmets develop “motor memory” skills that carry into games. Essentially, the players and their bodies learn how to avoid head injuries. “They’re keeping their head out of contact,” he said.

The approach may work for young football players and perhaps even the pros, Swartz said. But, he doesn’t expect that helmets will disappear from football unless there’s a radical rethinking of the sport.

Anthony Kontos is research director of the UPMC Sports Medicine Concussion Program and an associate professor of orthopedic surgery at the University of Pittsburgh. He called the study interesting, but cautioned that it has weaknesses.

Among other things, he said, it was small and didn’t report on concussions among the players. Nor, he said, did it make clear whether players benefited from the new practice routine itself or from not wearing helmets. It’s also possible, he said, that those who took part in the helmet-less practices focused more on head safety.

Whatever the case, he said, it’s still important to teach players about safe tackling. “They will have fewer impacts to the head by tucking the head away from the tackle,” he said.

Study author Swartz said researchers are seeking a grant to test the helmet-free strategy in high school football, because kids are especially vulnerable to brain injury.
