HPRC Fitness Arena: Environment
A staggering number of Americans (approximately 36 million) have hearing loss, and one-third of those probably could have been prevented. Hearing loss continues to be a safety hazard for Warfighters at home and in the field. So how do we combat this not-so-silent epidemic? Here are a few tips to help you protect your hearing.
- Wear a hearing protective device (HPD). HPDs should be worn for noise levels at or above 85dB. Not sure what 85dB really means? Check out this guide to occupational noise levels. Also check out “How Loud is Too Loud?,” a graphic designed to inform Warfighters about how and when to choose the proper HPD for their jobs.
- Learn how to wear your HPD correctly. Even if you have the correct protection, it may not be effective if you’re not wearing it correctly.
- Always have disposable HPDs handy. Disposable HPDs are lightweight and easily portable. Make them a part of your everyday gear.
For more information about how to protect yourself against or to seek help for hearing loss check out the DoD Hearing Center of Excellence website or make an appointment with your local hearing loss treatment center.
The word “antibacterial” is all too familiar to 21st-century consumers. Soaps and cleaning products that tout “antibacterial” or “kills germs” in large print seem to be everywhere. So it may surprise you to learn that recent studies suggest the use of antibacterial soaps may not be as beneficial as once thought. Research now shows that overuse of these soaps contributes to antibiotic resistance, which makes bacteria stronger and less responsive to antibiotic treatment—a potentially major problem in combat zones and hospitals. In addition, recent animal studies have shown that triclosan, the most common active ingredient in antibacterial soaps, may alter the way hormones work in the body. While these soaps are sometimes necessary in hospital settings, scientists caution against using them in our everyday lives.
FDA will now require that over-the-counter antibacterial soaps must prove that their benefit to a consumer’s health is greater than the current risk for harm to the user and the environment. Manufacturers of over-the-counter antibacterial soaps will be given until December 16, 2014, to provide this evidence or FDA will ban their products.
The ban will not affect hand sanitizers and soaps used in hospital settings. To learn more about the proposed ban of antibacterial soaps, read the FDA consumer update.
Remember to adjust your clocks one hour ahead on Sunday, March 9, to switch to Daylight Saving Time (DST). Sleep is important to your overall performance; losing just one hour can affect it. You don’t have to feel that loss if you prepare to spring forward:
- Adjust your bedtime. This can help you accommodate losing an hour of sleep. For example, if your bedtime is 10 p.m., try going to sleep earlier the week before so that you can handle the time change when it arrives. You can do this gradually by adjusting your bedtime in 15-minute increments each day leading up to the time change.
- Take a nap. Naps can help make up for sleep debt. If you are not fully adjusted when Sunday arrives, remember that it’s okay to use naps to adapt to your new schedule.
- Re-set your sleep habits. If you’ve thought about improving the quality of your sleep, this may be a great time to re-set your sleeping habits.
- Check DST observances. If you are travelling or deployed, remember to check if the state or country you’re in observes DST or if they do so on a different day. Arizona, Hawaii, and some other U.S. territories do not.
Maintain optimal performance and make the transition smoother with these tips. For more information on sleep and performance, visit our Sleep Optimization page.
Wanting some holistic strategies to enhance your performance? Check out the “One Shot One Kill (OSOK) Performance Enhancement Program” that shows Warfighters how to set up and manage their own performance-enhancement system. OSOK is designed not only to enhance performance but also to jumpstart Warfighter resilience. It builds on the skills that Warfighters already possess and then teaches new ones as needed.
There are two ways you can use OSOK: as an individual through “OSOK Solo” and as a unit/group through “OSOK-IP Unit.” Both highlight “10 Rules of Engagement” and provide seven core modules: Controlled Response, Mind Tactics, Performance-Based Nutrition, Primal Fitness, Purpose, Code, and Recharge. OSOK also provides self-assessment forms so you can track your progress over time.
For other performance-enhancement programs and information about holistic (total) fitness, check out HPRC’s Total Force Fitness domain.
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.
Winter’s not over yet. The next month or more can bring anything from ice and sleet to “Snowmageddons” and polar vortexes. Winter weather can be dangerous for you, your family, and even your pets if you’re not prepared. In the event of an emergency you should know what to do to protect yourself and your loved ones. The National Center for Disaster Medicine and Public Health has compiled a list of resources that offer information, tips, and checklists for winter-weather emergencies and general cold-weather health. Stay warm, safe, and resilient!
Have you heard the terms “resilience” and “Total Force Fitness,” but you’re not quite sure what they mean or where they fit into the health and performance picture? Read on.
Your health is the foundation. The 2010 article "Why Total Force Fitness?" states, “nothing works without health.” Health is not just physical and not just something to worry about when you’re sick. Health is a combination of physical, mental, spiritual, and social well-being and includes practices that promote wellness in addition to those that help you recover from sickness or injury.
Resilience is next. Resilience is the ability to bounce back—or even better, forward—and thrive after experiencing hardship. It is not the ability to completely withstand hardship but rather the ability to come back from it and grow stronger through the experience.
Next is human performance optimization (HPO). Unlike resilience, which typically requires the experience of hardship, HPO involves performing at your best for whatever goal or mission you have (whether that is your PT test, a combat mission, or raising children). It goes beyond simply resisting challenges; it means functioning at a new optimal level to face new challenges.
Health, resilience, and optimal performance are the foundations of Total Force Fitness, which is defined in the “Physical Fitness” chapter of “Total Force Fitness for the 21st Century” (see link above) as a “state in which the individual, family, and organization can sustain optimal well-being and performance under all conditions.” Being totally fit requires a holistic approach—that is, an approach that doesn’t focus on just one aspect alone such as nutrition or physical fitness, but on multiple domains of fitness. It means attending to your mind (including psychological, behavioral, spiritual, and social components) and your body (including physical, nutritional, medical and environmental components). In order to achieve Total Force Fitness, these factors come together to enhance your resilience and/or performance.
This is where HPRC can help you on your quest for total fitness. By visiting each of our domains—Physical Fitness, Environments, Nutrition, Dietary Supplements, Family & Relationships, and Mind Tactics—you can get evidence-based information on a variety of holistic topics to help you achieve and sustain total fitness. But remember that total fitness is a life-long process that will ebb and flow. And it isn’t just about you; your loved ones are an important piece of the picture, too.
In 2013, the Research Institute of Chicago (RIC) presented the first mind-controlled bionic leg, thanks to support from the U.S. Army Medical Research and Material Command's (USAMRMC) Telemedicine and Advanced Technology Research Center (TATRC). Until now, this technology was only available for prosthetic arms. These brainy bionic legs are still being studied and perfected, but it’s hoped that they will be available in the next few years. This life-changing technology will be able to help the more than 1,600 service members who have returned from Iraq and Afghanistan with amputations. Bionic limbs will make the transition to active duty or civilian life smoother for wounded warriors.
In one case study, a civilian who lost his lower leg in a motorcycle accident underwent a procedure called “Targeted Muscle Re-innervation”. This procedure redirects nerves that originally went to muscles in the amputated limb to still-healthy muscles in the limb above the amputation. As these healthy muscles contract, they generate signals that are detected by sensors within the prosthetic and analyzed by a specially-designed computer chip and program The program rapidly decodes the type of movement the individual is preparing to do, such as bending the knee, and then sends those commands to the leg. This allows the person to walk up and down ramps and stairs and transition between activities without stopping. The user also can move (reposition) the bionic leg just by thinking about it, which is not possible with current motorized prosthetics.
The bionic leg is also showing a decreased rate of falling and quicker response time. Stay tuned for availability of this groundbreaking technology.

The U.S. Centers for Disease Control (CDC) confirmed what has been suspected for a long time: Previously contaminated tap water at U.S. Marine Corps Base Camp Lejeune was linked to serious birth defects in babies born between 1968 and 1985.
Pregnant women on base were drinking tap water primarily contaminated by chemicals from an off-base dry-cleaning facility. Other chemicals from underground storage tanks, industrial spills, and waste-disposal sites were also detected in the water.
The water wells on base were shut down in 1985, but the damage had already been done. Pregnant women at Camp Lejuene were four times more likely to have babies with serious birth defects (such as spina bifida) as well as a slightly higher risk of developing childhood cancers.
The Veterans Administration continues to provide compensation for those affected by this exposure.
As you read this article right now, your eyes are working harder than they would if you were reading a book or even watching TV. Attention, desk warriors! If you stare at a computer for most of the day, you could leave work experiencing dry eyes, headaches, and blurred vision. 90% of people who work on a computer experience symptoms of Computer Vision Syndrome, or CVS. Symptoms include blurred vision, dry eyes, headaches, eye strain, irritation, redness, and any number of other ocular symptoms.
Computers have become a necessity in our world, so monitors are here to stay. Here are some of the causes of CVS and some tips to help you protect your eyes from the screen:
- Blinking. One of the main symptoms of CVS is eye dryness. This occurs for two reasons: First, your eyes are focusing on the same depth of field for an extended period of time; second, unlike the non-stop action on a TV screen, there may be little movement happening on your computer screen. The lack of movement and constant field depth leads to less blinking and, therefore, eye dryness.
Fix it by spending 30 seconds every hour or so adjusting your eyes to something far away. If you work in a small office, put up a picture and focus on something small in the background. This change in depth of field will exercise your eyes, and you’ll blink more!
- Monitors. The pixels on a computer screen can cause some problems. Because they are not all the same brightness, they don’t produce the same contrast. And they can cause words or pictures on the screen to look fuzzy, straining your eyes and contributing to CVS.
Fix it by investing in a good LCD monitor if you have not done so already. LCD monitors reduce glare and contrast, as compared with older types of monitors. If you already have an LCD monitor, then talk to an ophthalmologist about getting some reading glasses to help reduce eye strain. Adjusting the lighting in the room and/or on your computer screen can also help soften the symptoms of CVS.
- Existing vision problems. You may already have a vision problem that went undiagnosed until you started staring at a computer. Extended computer use can exaggerate already existing eye conditions and lead to some of the symptoms of CVS.
Fix it by talking to a physician about corrective lenses. The Vision Center of Excellence has excellent resources from the VA and DoD for vision support.
In summary: Protect your eyes from CVS by taking frequent breaks from the computer, by blinking more often, and by making sure you work in an ergonomically efficient office setup. If you want to more information about CVS, check out “A Survival Guide to Computer Workstations.”
