Questions families of Reserve & National Guard members need to ask

Asking some questions ahead of time can help families of National Guard and Reserve Warfighters when it is time to deploy.

HPRC recently posted an article with questions that parents of deploying Warfighters need to ask, but families of National Guard and Reserve Warfighters have additional challenges when their Warfighter deploys (such as being away from support at installations, financial changes, and shifts in childcare). It can help to think through some of these challenges and come up with a game plan ahead of time. Here are some examples to start with:

  • Who needs to know about the upcoming deployment? (Teachers, doctors…)
  • What’s the plan in case of an emergency (either stateside or while deployed)?
  • Will the childcare arrangements need to shift during deployment? (This is especially important for single parents.)
  • Will family income be reduced? Who will manage finances during this time?
  • How will family members keep in touch with the deployed Warfighter? Does everyone in the family agree, or are there individual preferences? (For example, your oldest child may prefer to Skype rather than write letters.)
  • Are there any military support organizations those at home can use for extra support?
  • Will any holidays or birthdays be missed during the deployment? If so, maybe something special can be done ahead of time and saved for the specific day.

For more information on resources for before, during, and after deployment, check out the “Deployment“ section of HPRC’s website.

Armed Forces Sports: Are you game?

Have you considered playing an organized sport for one of the military branches? DoD’s Armed Forces Sports offers opportunities in 25 team and individual sports for men and women. Check it out and see if you can take your game to the next level.

Are you tired of the usual morning jog or bike ride? Maybe you have a talent in a particular sport and want to take it up a notch to earn a spot on one of the Armed Forces Sports teams. You’ll find sports such as basketball and soccer, as well as sports at the more extreme end of the spectrum such as parachuting and Tae Kwon Do. One objective of the AFS program is to encourage physical fitness through sports competitions. Another is to provide means for military athletes to participate nationally and internationally. AFS holds U.S. and world championships, and in 2012 some athletes even took part in the London Olympics! If you are considering training for one of these teams, check out the Training & Exercise section of HPRC’s website.

Adjusting to work relationships after deployment

Deployment stress can sometimes hang around and impact work relationships after you are back home. Learn more about common issues and tips to deal with them.

The stress of deployment can linger when you return home and resume (or start new) work responsibilities and relationships. Sometimes it can be difficult to know how much to share about recent deployment experiences in the work environment, particularly if your coworkers are not or have not been in the military. Some may ask a lot of questions and others may steer clear of the subject entirely. This can create an interesting dynamic in your work relationships. Afterdeployment.org emphasizes that discussing your experience is a decision that’s completely up to you. So think ahead of time about how much (if any) you want to share, and be cautious about whom you choose to share with initially.

Afterdeployment.org also describes some common problems that can affect performance in the workplace. For example, combat experiences sometimes can impact your sleep quality, making it difficult to be at your peak at work. Other possible issues include inappropriate anger in response to people or situations and feeling uneasy and unable to let one’s guard down in a crowded office or worksite.  This Work Adjustment factsheet provides more information and tips that can help with common issues, and another on Informal Relationships at work for more information.

Sub terra firma

Combat training is moving underground. New tactics—and, potentially, new doctrine—are being developed to help troops perform in underground environments where enemies could hide.

The U.S. Army’s Asymmetric Warfare Group has been training joint forces in some unusual places—underground venues such as tunnels, caves, and sewers. As battlefields become more urban and enemies move underground, subterranean environments pose unique operational challenges. Although the Army does not currently have an official field manual for underground combat, this new tactical training has developed units’ ability to perform in these environments. Combat training centers are starting to integrate these kinds of complex environments into their facilities, and the Army is urging home-station training to “get creative” and use simple techniques to simulate their own underground environments. Something as simple as training in a dark room with obstacles can simulate underground areas. Israeli Defense Forces have also had success with this type of training. Being able to adapt and perform in challenging environments is a vital part of warrior resilience.

Got lactose (intolerance)?

Lactose intolerance can really put a damper on performance. What is it and what are some tips to handle this condition?

Do milk products make you queasy, gassy, or—worse—send you running to the bathroom? If so, you might have lactose intolerance, a condition caused by a deficiency of lactase, an enzyme produced in the small intestine. Lactase breaks down lactose, a naturally occurring sugar present in milk and milk products.

Symptoms of lactose intolerance include nausea, gas, cramping, and diarrhea and usually occur 30 minutes to two hours after eating milk products. Anyone (at any age) can develop lactose intolerance, but it’s more common among adults of African, American Indian, Asian, Jewish, or Mexican heritage. People who have digestive diseases such as Crohn’s disease, ulcerative colitis, or celiac disease are more likely to be lactose intolerant too.

Some people with lactose intolerance have to avoid all milk products, but others can handle small amounts of cultured milk products such as yogurt, kefir, or buttermilk. If you think you have lactose intolerance, experiment with milk products to see what you can handle.

Many processed foods (including MREs) contain milk products, so learn to be label-savvy: Look for words on food packages that indicate a product might have milk or milk products such as whey, curds, milk byproducts, dry milk solids, and nonfat dry milk powder. Missing your ice cream? Over-the-counter enzyme products can help you tolerate lactose-containing foods if taken with the first bite of food.

Don’t confuse lactose intolerance with milk allergy, an immune response to casein or whey, two proteins found in milk. Symptoms of milk allergy are typically mild and include:

  • Runny nose, sneezing, or shortness of breath
  • Swollen lips, tongue, or throat
  • Rash, hives, or itchy skin

However, severe milk allergy can cause anaphylaxis, a serious, life-threatening condition that requires immediate medical attention. People with severe milk allergy should read labels carefully to avoid all milk products.

Of course, limiting or avoiding milk products could put you at greater risk of developing osteoporosis or “brittle bones.” That’s because milk products contain calcium, an essential nutrient for healthy bones. Look for other calcium-rich foods such as dark-green leafy vegetables, almonds, beans, shellfish, or calcium-fortified juices, soymilk, or almond milk.

To learn more about lactose intolerance, read this informative article from the National Digestive Diseases Information Clearinghouse.

Mental imagery is no magic trick—it’s an essential training tool. Learn why and pick up some tips on how to make these mind rehearsals as productive as possible.

A popular sport psychology technique Warfighters can use is mental imagery. This is the practice of seeing (and feeling) in your mind’s eye how you want to perform a skill, as if you were actually doing it. It can augment your usual training and help you maintain—or even surpass—your current skill level, even when you’re sidelined.

Some of the ways that imagery helps performance include:

  • —  Better decision-making
  • —  Fewer errors
  • —  Improved attention
  • —  Increased confidence
  • —  Reduced stress and anxiety

You can generate imagery in your mind for just about any task (improving your running time or marksmanship, for example). Good mental imagery incorporates all of the senses, and it often helps to listen to a scripted audio recording. You can create your own and/or work with a CSF Prep Master Resilience Trainer-Performance Expert to develop one.

Watching others can also help. In fact, being a spectator can boost learning even more than mental imagery by itself because you’re viewing what you’d like to accomplish rather than conjuring up images with your own mind. Both methods of learning are effective. Observing can be in-person or by video, but you can also combine video/imagery approaches and potentially get even more bang for your buck.

With either approach, or with the combined approach, it is important to “feel” yourself executing the skill, even though you might be sitting or lying down. Of course, imagery doesn’t have to be done while you’re sitting still. Try using imagery in the setting where you’ll actually perform the skill. You can even incorporate it into existing training protocols.

Watch HPRC for future posts where we’ll explain how to create your own imagery. Until then, check out other mental performance skills located in Mind Tactics.

Building family resilience

Further strengthen your family’s resilience with this new resource that discusses how to build it during and following deployment.

Building family resilience is a process that lasts a lifetime, but it can be immensely rewarding. But what is resilience and how can military families in particular build it? HPRC has a resource called “Building Family Resilience” that can give you answers to these questions. The article covers military-specific stressors for families—including how deployment and reintegration impact family relationships, war-related physical and mental health conditions, and individual stress responses and risky behaviors in family members, both adults and children. It also highlights three key resilience-building skills—mind-body, cognitive-behavioral, and communication—and highlights resources to build resilience. Check it out.

What’s the big IDEO?

The Intrepid Dynamic Exoskeletal Orthosis (IDEO), a new orthotic technology designed for limb-salvage patients, helps Warfighters return to running, sports, and combat.

The U.S. Army has developed a device that will not only reduce the number of amputations but will help severely injured Warfighters return to duty. In the past, Warfighters with crushed and battered legs faced amputation or, at best, dysfunction due to pain and weakness. Now, with the introduction of the U.S. Army’s newest orthotic technology, amputations and decreased mobility may be a thing of the past for some.

The Intrepid Dynamic Exoskeletal Orthosis (IDEO) is the latest orthotic technology designed for Warfighters whose legs were crushed in combat. It uses technology similar to that of prosthetics worn by amputees and is higher in user satisfaction and performance compared with other braces available. Unlike other braces, IDEO does not depend on ankle movement, so Warfighters with fused ankle bones, where function is limited, can use them with little pain. With each step, IDEO stores energy and transfers it to the back of the brace, which springs the leg forward (similar to running-blade prosthetics). This allows the wearer to continue rebuilding the muscles in his or her leg while also working on functional movement.

In a study conducted by the Center for the Intrepid, eight of ten patients fitted with IDEO were able to run at least two miles without stopping. All ten Warfighters returned to weightlifting, many returned to playing sports or participating in mini-triathlons, and three returned to combat—two with Special Forces and one Army Ranger. The published report emphasized that the success of these patients was due not only to the innovative IDEO but also to the intense rehabilitation program and—most important—the motivation and drive of the individuals.

In combination with rehabilitation programs, IDEO looks like the newest in a wave of innovations that will help Warfighters return to normal function. If you are interested in learning more about IDEO and other innovative rehabilitation programs, please visit the U.S. Army Institute for Surgical Research and the Brooke Army Medical Center’s Center for the Intrepid.

Eat after eight, put on weight?

HPRC Fitness Arena: Nutrition, Total Force Fitness
Does late-night eating really contribute to weight gain? Research suggests it just might.

There’s an old adage you may have heard: “Eat after eight, put on weight.” And maybe you’ve experienced it first-hand: You noticed that eating those late night pizzas and ice cream really packed on the pounds. But was your weight gain due to timing or just the high calorie counts? According to research in the field of circadian rhythms (CRs)—the 24-hour cycle of your body’s biological, hormonal, and behavioral patterns—it seems that when you eat could be just as important to weight gain as what you eat.

Deep within your brain sits a small cluster of nerve cells—a “master clock” of sorts—that’s responsible for orchestrating your CRs. Each biological system in your body works on a different CR schedule, and the master clock keeps all the schedules in sync. For example, CRs influence your body’s production of the hormones that regulate hunger, as well as how your body uses and stores fats and sugar, ultimately influencing your body weight, performance, and overall health. Other hormones, such as the ones that tell you when you’re full, are switched on or off according to a variety of inputs.

The two greatest influences on how well your master clock is able to keep things in sync are light and food. Light tells your brain how much sleep you get (think: eyes closed, less light). Food (smell, taste, and consumption) tells your body to produce a myriad of chemicals. As a result, staying up late at night, working shifts, and eating at all hours of the day and night—whether voluntarily or due to the demands of overseas deployments, training demands, shift-work schedules, and even parenthood—can play havoc with your circadian rhythms.

In an interesting twist, not only do CRs influence hunger and body weight, but excess body fat and/or a high-fat diet may disrupt CRs. This can lead to further weight gain, culminating in a collection of health problems known as “metabolic syndrome.” In the U.S., regular loss of sleep closely parallels the occurrence of metabolic syndrome. In addition, researchers have found that people who sleep less or have poor-quality sleep are more likely to become obese.

What to do? Make a conscious effort to “normalize” your daily routines as much as possible to maintain regular mealtimes. Whether you choose to eat three regular-sized meals or four to six smaller meals a day, space them out through the daylight hours to take advantage of your body’s natural rhythms. Here are some suggestions to avoid eating late at night:

  • Try to eat a balanced dinner at least two hours before you go to bed, and take a walk afterwards when possible.
  • Sip on soothing herbal tea or flavored water (without sugar).
  • Be aware that watching TV (especially food-related ads) can trigger your desire to eat.
  • Sometimes it can help to create new nighttime rituals that don’t involve eating, such as light stretching or yoga, taking a warm bath, listening to soothing music, or reading (or listening to) a book.

But if you find yourself up late at night—whether it’s due to a hard day at work, regular shiftwork, or temporary shifts due to jet lag or an infant’s night feedings—resist the urge to snack out of boredom or to “keep your energy up.” Shift workers should pack or purchase a healthy meal to eat during their work hours—one that includes lean protein and complex carbohydrates such as whole grains, fruits, and vegetables. Eat early in the shift if possible, so you’ll have the energy you need to think and move efficiently. Travelers and parents should look for healthy snacks that follow a similar pattern. And try to limit coffee, tea, and other sources of caffeine to just two to four servings a day.

Of course, eating is just one half of the CR equation. Getting enough sleep is important too, so read HPRC’s overview for great tips on how Warfighters can improve their sleep.
