Antigravity treadmills are becoming increasingly popular in injury prevention and rehabilitation settings. These special treadmills reduce the stress placed on the lower body during rehabilitative exercises, like running and walking, while still conditioning muscles. However, there are still questions as to whether the scientific evidence supports their considerable cost. For more about the use, evidence, and cost of these devices, read HPRC’s “Effectiveness of Antigravity Treadmills for Injury Rehabilitation.”
Stress isn’t an isolated event. It can infiltrate your life in many ways. A survey of more than 12,000 military personnel across the services revealed the impact of stress levels on Warfighter performance. Compared with those with low stress, Warfighters with high stress were much more likely to be late for work, leave work early, get hurt on the job, or miss work altogether because of illness or injury. These trends were especially strong among a smaller subset of personnel who had recently needed a mental health evaluation. Other research suggests that stress can combine with a person’s (often unknown) predispositions, sometimes triggering mental health issues.
Depending on the severity of mental health concerns, focus on performance can take a back seat. So stress, mental health, and performance often go hand in hand. Stress-management techniques and proactive approaches to mental health can help stressed Warfighters perform their best.
Iodine is an essential nutrient. It plays a key role in how well your thyroid functions and is particularly important during pregnancy and breastfeeding for the development of your baby’s brain. The Recommended Dietary Allowance for iodine for most adults is 150 micrograms (mcg). But women who are pregnant or breastfeeding need slightly more: 220 mcg and 290 mcg daily, respectively.
Iodine is present in some foods such as fish, dairy products, fruits, vegetables, and grains. Iodine is also added to table salt—referred to as “iodized salt.” Although most Americans eat too much salt, much of it comes from processed foods and typically isn’t iodized. Consequently, many women who are pregnant are iodine-deficient. If you’re pregnant or breastfeeding, the American College of Obstetrics and Gynecology and the American Academy of Pediatrics recommend taking a prenatal vitamin to ensure you’re getting enough of all your vitamins and minerals, including iodine. In addition, if you’re vegan or you don’t eat dairy products or fish, talk to your doctor about your iodine status.
Read all prenatal dietary supplement labels carefully—whether they’re prescription or over-the-counter—so you can be certain your prenatal vitamin contains sufficient iodine to meet your needs during pregnancy and breastfeeding. Also, be sure to look for one that is third-party certified. For more information about iodine, read this fact sheet from the National Institutes of Health’s Office of Dietary Supplements.
Whether training for a mission, an athletic event, or simply to maintain your edge, there are strategies you use to enhance your chance of success, including “rules” such as figuring out where you are before you start and setting up an environment that supports your new plan. Check out HPRC’s new card, “Peak Performance: Rules of Engagement,” to learn all of them. And for even more information, check out the accompanying Performance Strategies.
The Military Health System has declared that June is Men’s Health Awareness Month. Understanding your personal health risk factors and getting screened for potential issues is the best way to stay healthy at any age. Prostate, lung, and colorectal cancers are the three most common cancers among men. The good news is that exercise and physical activity have been liked to lower risk and lower rates of death for these types of cancers. So stay active and visit a doctor for regular health screenings, and pass on to the boys in your life about the importance of regular exercise and physical activity. Living a healthy lifestyle and getting screened for health issues are important ways to maintain readiness, resilience, and optimal performance.
Even ten years ago, one survey found that nearly 70% of patients admitted to emergency and intensive care medical facilities did not inform the medical personnel of their dietary supplement use. However, some dietary supplement ingredients can retard the effects of prescription medications, others can intensify their effects, and yet others can be the reason a patient arrived at the emergency or intensive care facility in the first place. For example, more than 90 dietary supplement ingredients are known to affect blood clotting, which could mean that a wounded Warfighter could bleed more heavily than an emergency medic might otherwise expect.
According to an April 2014 article in Critical Care Medicine, recent adverse events associated with dietary supplements highlight the importance of letting medical personnel know if you are taking any supplements. As we pointed out in a recent article, you become the essential participant in making sure that your use of dietary supplements does not lead to serious consequences. Be sure you tell medical personnel about your dietary supplement use before you receive treatment. It could save your life!
We’ve said it before: The Nutrition Facts label on a food package can be a Warfighter’s best friend. But it might be getting a facelift, so to speak, to reflect the latest scientific information, courtesy of the Food and Drug Administration (FDA). The overall “look” of the label will be almost the same, but certain parts will change or be enhanced. Here are some of the proposed changes:
- Serving size: Updated to reflect the way people eat and drink today
- Calories and Servings: Shown in larger type
- Daily Values (DVs): Updated for various nutrients, such as sodium, dietary fiber, and vitamin D
- % DVs: Listed first because it’s easier to read left-to-right
- Added sugars will be shown on a new line.
- DVs for vitamin D and potassium will be included.
- Calories from fat: Going away because according on research, the type of fat is more important than amount. However “Saturated Fat” and “Trans Fat” will remain on the label.
Take a look at the old and new versions side-by-side and then visit HPRC’s Facebook page to tell us what you think of the proposed changes! FDA is seeking comments on the proposed changes, and the closing date has been extended until August 1, 2014, so this is your opportunity to be heard.
Reconnecting with your family when you return from deployment presents unique challenges, especially with young children. Depending on how long you were deployed—a few months to a year or more—a lot could have happened in your child’s life while you were away. If you’re finding it hard to reconnect with your child, you’re not alone. Military Parenting’s website has tip sheets that describe typical behaviors for different stages: infant, toddler, preschooler, school-aged, and teen. Just knowing what’s typical for you child’s age can help you reestablish your relationship.
Reconnection can occur in small, everyday moments when you respond to your children’s needs and provide them with support and nurturing, such as holding them when they cry, playing games or sports together, being silly and laughing, taking a walk together, or eating dinner together and talking about your day.
For more tips on reconnecting, check out “Reestablishing Your Parental Role,” also from Military Parenting, a website devoted to parenting resources for Warfighters. For more tips on returning home, check out “Building Family Resilience...During and Following Deployment.”
More than two million new cases of skin cancer are diagnosed each year, and the number is growing. Skin cancer is a major public health issue, and with proper precautions you can decrease your risk considerably. Hopefully this information on sun safety will help you, whether you are a Warfighter or dependent, stay safe during all outdoor activities!
Ultraviolet radiation (UVR) has been identified as the most important risk factor for both melanoma and non-melanoma skin cancer. Exposure to UVR weakens the skin’s elasticity and can result in sagging cheeks, deeper facial wrinkles, skin discoloration, burn, skin aging, photosensitivity, and cancer. Taking steps to safeguard yourself is crucial, especially when participating in outdoor activities or exercising.
Sweating increases the skin’s sensitivity to the sun’s rays, magnifying the risk of sunburn and skin damage. Athletes who practice outdoor sports have been found to be at increased risk for skin cancer. Remember—the weather does not have to be sunny and hot for you to get sun damage. Ultraviolet rays penetrate clouds, exposing you to 80% of the UVR. Even skiers and mountain climbers are at risk for sun exposure and skin cancer because of the stronger UVR at altitude.
Follow these precautions from the Occupational Safety and Health Administration (OSHA) whether training for the PRT, patrolling, road marching, or participating in a summer league softball game:
Avoid burning. Avoid sun tanning. Also, try to avoid sun exposure during midday (11 a.m. to 3 p.m.) when the rays are the strongest.
Seek shade. When possible, especially during midday, seek shade under a tree or tent.
Cover up. Wear protective clothing, including hats, long-sleeved shirts, and pants when going outdoors. Keep in mind protection decreases when clothes are wet.
Use extra caution near water, snow, and sand. Ultraviolet rays can reflect off of these surfaces, which can increase your chance of sun exposure and skin damage.
Apply sunscreen. Use water-resistant sunscreen and apply 15-30 minutes prior to sun exposure to allow for it to absorb. Also, reapply after swimming, sweating, or toweling off. Be sure to take a look at the new FDA regulations regarding sunscreens and their effectiveness.
Wear sunglasses. Protect your eyes when working, driving, participating in sports, taking a walk, or running an errand. Solar ultraviolet B radiation can cause an increased risk of cataracts and cancer of the skin around the eye without proper cover.
It’s always important to remember hydration when engaging in outdoor activities as well! HPRC has useful tips on hydration and the consumption of sports drinks and caffeine during exercise in the heat.
