Just like athletes, Warfighters need great balance systems for optimal performance. Your inner ear plays a big role in your ability to stay balanced and upright by sending messages to your brain about the movement of your head and body (rotating, forward, back, up, down, speeding up, or slowing down). The collection of nerves and other parts of the inner ear that form this sensory system is known as the “vestibular system.” We know that this system is more highly developed in athletes, but some evidence suggests that training the vestibular system can improve balance in less-trained athletes and non-athletes as well.
The vestibular system can be trained, much the same way as a muscle, after injury to the ears or brain, so that patients can experience normal balance again and reduce dizziness symptoms. Medical professionals and therapists use three approaches, which they can teach individuals to do on their own:
- Adaptation. Find the areas of your vestibular system that are “off” (vision, timing, balance, or dizziness) and practice eye-head coordination to regain that skill.
- Substitution. Learn to use different parts of your vestibular system to get the information you need to correct your balance and dizziness.
- Habituation. Challenge your system incrementally (for example, just to the point of feeling seasick) to improve your tolerance of an activity.
Since these treatments can restore normal function in the injured athlete or Warfighter, then it’s possible that this kind of therapy can also help healthy service members develop exceptional ear-balance systems and other crucial Warfighter skills. More research is still needed, but the outlook is promising.
Food and color additives exist in many of the foods that we eat. They are used to improve safety and freshness, maintain the nutritional value of foods, and improve texture and appearance. The Food and Drug Administration (FDA) has put together a helpful brochure reviewing how additives are approved for foods, types of food ingredients, and a description of food and color additives.
When performance matters, it’s common to feel amped up—your heart beats faster, for example. How you interpret these physical sensations can change how you feel emotionally, including your overall mindset, and ultimately make a difference in how you perform. Recent research into performance anxiety over tasks such as singing, public speaking, and math gives us some insights about performance anxiety in general.
It’s normal to interpret some physical signs as performance anxiety. When you feel amped up, it may be difficult—or even impossible—to simply “decide” to feel calmer, because it isn’t consistent with what is happening in your body. And trying to pretend you’re calm can actually make you feel more anxious. But because your body has some of the same reactions—increased heart rate, “butterflies,” etc.—when you’re excited, you can actually feel excitement and anxiety at the same time by simply saying “I’m excited!” or deciding to feel excited. This doesn’t make the anxiety go away, but adding a layer of excitement over it can be valuable to how you think and ultimately perform..
Excitement feels good and puts your mind on a different track. When you’re excited, it’s easier to become aware of opportunities instead of potential threats. And this “opportunity mindset” leads to better performance.
So when you feel anxious about performing on the PRT, with marksmanship, or for any other task, remember that it’s normal. Convince yourself to feel excited. Allow yourself to see the opportunities. And in turn, enjoy better performance.
Have you ever left a doctor’s appointment only to realize that you couldn’t remember half of what he or she told you? Or that you forgot to ask some important questions that had been on your mind?
It happens to all of us. Even routine visits can be unnerving. One of the ways you can help avoid these two scenarios is to write things down. It sounds simple, but it can be a helpful habit. Before you or someone you loves goes to a medical appointment, take a moment to jot down any issues or questions that you want to discuss. Have that piece of paper handy to refer to when you see your healthcare provider. Better yet, get a small journal that can fit into your pocket/purse/bag and track all your health statistics and questions in one place over the year.
Remember to jot down your provider’s answers to your questions. And while you’re there, take a moment to repeat back the main points to make sure you understood them correctly. If you are unsure about something, continue asking questions until you understand the issue.
For appointments that are more complex, consider bringing along someone you trust to take notes for you.
Getting an extra hour of sleep is a dream come true for many of us. For others, the end of Daylight Savings Time means an extra hour on the town or time to catch up on a to-do list. No matter how you choose to spend your extra hour, the amount of sunlight typically decreases over the following weeks, depending on where you are in the world. The change in daylight may influence your outdoors activities, so take this time to make a plan for how to remain active in the upcoming “dark days” of Standard Time.
Plan ahead for outdoor activities in the dark:
- If you jog or hike outdoors in the morning or evening hours, wear reflective or light-colored clothing to be easily visible.
- Plan your route ahead of time and let someone know when and where you will be exercising.
- Have a cell phone handy in case of emergencies.
- Be vigilant. A head-mounted flashlight can help you see holes and debris in your path to avoid sprains and injuries. Also beware of animals that might spook as you pass them in the dark.
- If you must wear earphones, only use one ear bud.
- Bring a buddy or pet!
Plan fun activities indoors:
- Move your exercise routine indoors. Whether in the gym or at home, there are plenty of ways to stay active. Try High Intensity Tactical Training (HITT) for a vigorous workout. Or take this time to give yoga a try or deepen your practice.
- Plan activities that get the entire family involved. Even if you don’t have a gaming console, you can try dancing, hula hoop, or a jump-rope contest. HPRC has more family fitness ideas you can try.
- Finally, think about how much sleep you usually get. Do you get the recommended seven to eight hours every night? This extra hour might be the jumpstart you need to begin prioritizing sleep. For more information on sleep tips, check out HPRC’s Sleep Optimization section.

Think of mental health treatment as a blend of science and art: scientifically proven treatment from a skilled psychotherapist who engages each patient as an individual. In standardized treatment, practitioners follow a specific protocol dictated by research studies. But even standardized approaches need wiggle room for the differences between human beings, both patients and practitioners. A lot of successful psychotherapy comes down to the relationship between the practitioner and the patient rather than the techniques, so there has to be some flexibility to it.
Evidence-based practice blends the best research evidence available (studies that have met certain criteria) with practitioners’ own clinical expertise, while also considering the patient’s values and preferences. Thus, good healthcare practitioners ask questions of their patients and pay attention to their perspectives. While it can feel vulnerable to lay it all out there, it is important to give honest responses. On the flip side, it is reasonable (and empowering!) for patients to ask providers why they are doing what they are doing. When the process is evidence-based, the provider will be able to describe his or her rationale while tuning into what makes sense for you as an individual.
Anger can be helpful in combat situations, and it can help individuals engage in quick, decisive action. It also can help keep emotions such as guilt and sadness at bay so you can accomplish things you need to do. Anger has its place. In relationships, anger is bound to make its way into interactions sometimes. When regulated, it can help you solve problems or motivate you to talk about important things, including hurt feelings. When unregulated, however, it can damage your relationship and increase your unhappiness with your loved one. Increased levels of anger can even increase your risk for physical health problems, especially coronary heart disease. It isn’t possible to avoid anger completley, but you can learn how to manage it well. Read more in HPRC’s “Performance Strategies: Five Steps to Managing Anger.”
Pain can be unpredictable, uncontrollable, and unrelenting, so even the most resilient Warfighters can be vulnerable to it. Because of pain, you may experience symptoms of anxiety or depression; your mind may even exaggerate the intensity and awfulness of pain. Socially, you might experience criticism, rejection, and negative interactions with family, spouse, or peers. Even if interactions are generally positive, you may want to withdraw from people or difficult situations
Chronic pain, which lasts longer than three months and is unresponsive to treatment, can affect quality of life for many. At least 100 million adults in the U.S. suffer from chronic pain. Unfortunately, combat and other situations make Warfighters especially susceptible to experiencing injury and pain. One study of an infantry brigade found that three months after return from Afghanistan, 44% of the soldiers reported chronic pain.
The American Psychological Association has shared evidence that relief from pain is more likely when mind and body are both treated. The National Center for Complimentary and Alternative Medicine has also indicated that continued study of non-drug approaches to pain management is a priority.
The latest trend in treating pain is the “biopsychosocial model,” which focuses on exercise and sleep (not just meds and surgery) as important biological influences. Important psychological factors include thoughts, emotions, behaviors, and attention. And impactful social factors involve healthcare, family, and work. All of these factors can contribute to understanding and mitigating the impacts of pain.
The American Psychological Association shares concrete advice to manage pain, including these tips:
- Distract yourself.
- Stay active and exercise.
- Know your limits.
- Follow prescriptions carefully.
- Make social connections.
- Don’t lose hope.
October is Breast Cancer Awareness month; but what’s important is that, after October is over and the sea of pink has ebbed, you turn your awareness into action if you haven’t done so already. Gentlemen take note: Men can get breast cancer too. Early detection can be critical for dealing with breast cancer. Make sure you conduct regular breast self-exams. If you find anything that worries you, talk to your doctor right away.
While your genetics play a role in the development of some breast cancers, exercise is also an important lifestyle tool to reduce your risk for this and other cancers such as lung and colon cancer. It may even improve your chance of recovery if you’ve already been diagnosed. Numerous studies have found that regular exercise can reduce your risk for breast cancer by an average of 25%.
It’s never too late to start getting active. While exercise at any age can reduce your risk for breast cancer, the greatest benefit seems to be for adult women, especially those over the age of 50. It’s important to be physically active throughout the day, not just when you’re exercising. Studies have shown that sitting and other sedentary behaviors for long periods of time can negate the effects of regular exercise, for general health and cancer prevention. The good news is that household and recreational activities, followed by walking/cycling and occupational activities, have the greatest impact on reducing risk for breast cancer.
Exercise and physical activity during cancer treatment also can be healthy for mind and body, can manage fatigue, and may lower the risk of progression. If you have already been diagnosed with breast cancer, talk to your doctor about what kinds of activities are safe for you to do while undergoing treatment. Just another reason to get out and get active!
