HPRC Fitness Arena: Total Force Fitness
In a 1960s TV cartoon series, George Jetson of The Jetsons simply popped a pill when he wanted to eat. “Dinner in a pill” was promised as the food of the future. So why hasn’t technology delivered on its promise? Simply put, no dietary supplement can reproduce the aromas, flavors, textures, or nutritional value of oven-roasted turkey, crusty, fresh-baked bread, juicy ripe pineapple, fragrant hot tea, or any other wholesome, delicious, performance-enhancing real food or beverage. And substituting dietary supplements for real food won’t help performance either – check out our video here. So skip supplements—not meals. To learn more about how real foods should come before dietary supplements, check out HPRC’s article in Operation Supplement Safety (OPSS).
The phrase “Garbage in, garbage out” was coined first by computer experts back in the 1960s. Since then, the phrase has gained a wider usage—even to the world of performance nutrition. Providing your body with high-quality fuels and nutrients is crucial to optimizing your performance. Like the poorly fueled runner in HPRC’s video, you’re likely to find that a diet of high-fat or sugary foods and drinks (“garbage in”) produces less than optimal results (“garbage out”). Instead, choose wholesome foods such as lean meats and fish, fresh fruits and vegetables, whole grains, and low-fat dairy products, which provide high-quality fuels and nutrients.
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.”
Check your money assumptions
Continuing our series on keeping the happy in the holidays this year, this week’s tip is to check your money assumptions. Finances can be strained during the holidays. This is not just an emotional problem, but how you think about money can affect you emotionally. Do you find yourself thinking, “I must give my family as good a Christmas as I had as a kid” or “I should be able to buy my kids whatever they want”? The fact is, you may like things to be different, but must or should they? Get rid of words such as “must” or “should” and focus instead on thoughts such as “What can I afford?” and “Are there ways I can make the holidays special without spending a lot of money?” Then notice how you feel without the constraints of what you must or should do. Instead, give yourself permission to give your family the holiday you can afford this year.
Happy Thanksgiving! In HPRC’s series on “Keeping the Happy in the Holidays,” this week we focus on being a gratitude-seeker. Gratitude is a state of mind that that can be hard to foster in our busy lives, particularly during the holidays. This holiday season set some time aside for gratitude.
The Defense Centers of Excellence suggests some tips for cultivating this skill, including:
• Spend two minutes a day thinking about what you are grateful for,
• Write five things daily in a gratitude journal
• Look for things to be grateful for in your everyday life.

Many Warfighters exposed to bomb blasts in the field walk away unscathed—or so it would seem. However, there could be some damage they’re not “seeing.”
Many Warfighters survive bomb blasts without obvious injuries, but the high-pressure shockwaves from explosive blasts can cause serious physical damage to a Warfighter’s eyes. In fact, up to 10% of all blast survivors experience significant eye injuries, either from projectiles thrown into their eyes, eye perforations caused by the high-pressure blast waves, or effects on the eyes associated with traumatic brain injury (TBI). If you were exposed to a blast while in the field but were not otherwise injured, don’t wait to set up an appointment with your eye doctor. Your vision is extremely important! Don’t let potential eye injury go untreated. For more information on how blast waves can affect your vision, visit the Vision Center of Excellence.
No one wants to experience foodborne illness. However, there are safety tips and techniques that will help prevent such incidents. The Food and Drug Administration has developed Food Safety Tips for Healthy Holidays, which includes other helpful links about food safety.
Before 2013 comes to a close, the Navy will begin distributing Flame Resistant Variant (FRV) coveralls to all Sailors assigned to surface ships and aircraft carriers. Previously, only Sailors working in engineering departments, on flight decks, and in other high-risk areas were issued flame-resistant clothing. However, a recent review found that the highest risk of severe injury from flames was from major fires or explosions, which puts any Sailor at risk. Tests revealed that the Navy Working Uniforms (NWU) type I, made of a polyester cotton blend, are susceptible to melting in a fire, which could cause even greater injury to the wearer. The new FRV coveralls are 100% cotton with a fire-resistant coating, which is self-extinguishing. The Navy plans to improve and standardize all coveralls over the next couple years by combining the protective effects of flame resistance, arc-flash protection, and low-lint specifications into one safe and effective uniform.
HPRC’s series on staying happy over the holidays started last week (read the first BLUF here). This week, try experimenting with your expectations in order to sail through the holidays with a smile.
If you have visions of the holidays being a certain way—with lots of fun, togetherness, love, joy, and no discord—you may feel disappointed when the reality turns out to be something else. It’s natural to feel this way, but take stock of how your expectations perhaps contributed to your disappointment. Try experimenting with different ways of looking at things. For example, think about what’s behind your holiday expectations. Is it really a happier holiday when you spend more money? Can the entire holidays be filled with fun? Can you get along with everyone all the time? Are your expectations realistic?
Afterdeployment.org describes how to foster realistic thinking and have a clearer lens to the world by focusing on what is probable instead of wasting time thinking about things that are unlikely. In other words, focus on what you can control, not what you can’t. This can be particularly helpful for your relationships.
The holidays are supposed to be a time of joy, but for many the expectations around the season leave them feeling depressed, lacking in motivation, feeling family friction more acutely, and on top of all of that, vulnerable to overeating. Now’s the time to shift your thinking to stay happy this holiday season. Check back every week as we present tips on how you can do this for yourself.
Tip #1: Shift your thinking to decrease stress
Realistically, it’s unlikely you can make holiday stress just go away, but you can change your response to that stress. Noticing your thoughts and emotional reactions can empower you to experience different, less-charged reactions, resulting in more positive thoughts and actions. Learn about the common thinking traps that you can get stuck in and how to reframe them. Noticing and then shifting your thinking can have a big impact on what you feel—try it out and see for yourself.
