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.
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.
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.
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!
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.”
Listening is half of communication. The other half is what you say and how you say it. The best way to express yourself is to be assertive. Assertive communication feels neither aggressive nor passive. It’s a balance between issuing a directive and being overly cooperative.
Communication between siblings can provide some good examples. Here’s the super directive approach: “You need to call me too. Don’t make me do all the work to keep up our relationship.” That may make sense, but the other person may not take it in because it triggers defensiveness. And here’s the overly cooperative approach: When your sibling says, “I hope you don’t mind that I never call,” you reply, “No, it’s okay, whatever you want is fine” (even if it isn’t). An assertive approach would be: “I’d really like to talk with you on the phone more, and I know you’re busy. What can we do to stay in better contact?”
The approach is basically a combination of “This is what I need” and “Can you join my team in figuring out a solution?” It’s straightforward and mutually empowering, opening the door for real communication. And for the other half of the communication equation, read last week’s article about how to be a good listener.
Prescription stimulants can improve attention and alertness, and doctors prescribe them for people with Attention Deficit Hyperactivity Disorder (ADHD) or excessive fatigue. Used improperly and without the supervision of a health provider, these drugs have serious side effects. Some people misuse and/or become addicted to them. Learn more in HPRC’s “Stimulant drugs: use and misuse.”
Last summer the Netherlands removed the weight-loss dietary supplement product Dexaprine from the market due to reports of serious adverse events, but the results of research into the cause has just been released. A recent article in Drug Testing and Analysis described at least 26 cases of Dexaprine toxicity reported to the Dutch Poisons Information Center. Testing revealed the existence of “a cocktail of synthetic stimulants” including synephrine, oxilofrine, deternol, yohimbine, caffeine, and theophylline, and possibly ß-methyl-ß-phenylethylamines. (Problematic forms of phenylethylamines, including ß-methylphenylethylamine. were discussed in an April 2014 article in the New England Journal of Medicine.) For more information about tainted weight-loss dietary supplements, see the Food and Drug Administration’s information. Note that this product is still available in the U.S. and online.
If you find yourself at odds with those around you more than you’d like, think about bolstering your communication skills. Communication is a key skill in all relationships, and half of this skill is knowing how to listen. “Active listening” lets your loved one, friends, and associates know that you heard them and understand their perspective. Active listening happens when the listener—you—takes part in the conversation, not just listens. Here’s how you do it:
- Repeat back to the other person the gist of what he or she just said.
- Reflect the other person’s feelings; that is, recognize out loud that you understand how he or she feels
- If you need clarification, ask for it in a gentle way.
- Show interest and curiosity in what the other person is saying.
To see what this might look like, watch this video from the Kansas National Guard about active and constructive communication. FOCUS has a handout on “Effective Communication Skills” that further describes this skill.
