Optimism is a hallmark of resilience, and being optimistic can enhance your performance. Having a positive outlook can also help you harness your mental and physical strength to deliver your best performance, no matter the conditions. Whether you’re facing physical, mental, or emotional challenges, learn how to shift your thinking from negative (pessimistic) to positive (optimistic), and see how an optimistic perspective can help you achieve a greater outcome. For help on how to accomplish this, check out HPRC’s "Reframe your thoughts for peak performance."
Pentagon scientists are hoping to build special gear designed to turn divers into veritable Aquamen (and Aquawomen). Although it’s still in the research phase, the new system would protect divers from the adverse effects of diving too deep or surfacing too fast. Sensors would read and adjust to a diver’s physical signs as well as help control levels of nitric oxide to prevent the decompression sickness known as “the bends.” When a diver ascends too quickly, bubbles form inside the body, which can block the blood vessels in the spinal cord and disrupt the nervous system. It can be very painful and can lead to joint pain, paralysis, and even sudden death if a diver is not careful.
The new diving gear will be a portable and versatile system that can potentially serve for use in other special operations as well as for civilian divers. This system will have to be designed for the most extreme combat dive profiles, which sometimes require a 35,000-meter free-fall from an aircraft, diving 200 feet below the surface for at least two hours, surfacing, and immediately diving again, followed by continued protection after being picked up in an unpressurized aircraft. This is one of DARPA’s most recent Small Business Innovation research proposals for 2013.
Researchers have long been interested in meditation and its potential benefits. A recent study found that regular meditation practice of 20 minutes a day has a lasting effect on how your brain processes emotions. This suggests that meditation could potentially help your brain handle stress, anxiety, and depression, and possibly other feelings. For those individuals dealing with relocation, deployment after-effects, chronic stress overload, recent family changes, or new training assignments, having a strategy to improve your resilience and help process the expected extra doses of emotions can be helpful.

If you exercise regularly—or plan to start an exercise program—chances are you’ll experience shin splits at least once. That sharp, achy, sore, and/or throbbing feeling that runs down the front of your shin, also known as “tibial stress syndrome,” is a common condition among athletes, especially runners. The pain of shin splits can come from any number of underlying causes, such as overuse injuries, “flat feet,” or a more serious injury—stress fractures—usually from excessive and/or repetitive force on your legs. Usually shin splits will heal on their own with rest and basic self-care treatments, but it’s important to recognize the symptoms early on and to give yourself time to fully heal before easing back into your usual workout. See a doctor if the pain does not seem to improve with rest, if your shin is hot and inflamed, or if the swelling gets worse. To prevent shin splits, make sure that you wear the appropriate shoes for your type of foot, warm up before working out, vary the types of surfaces you run on, and address symptoms of pain early.
"The grass is greenest where it is watered. When crossing over fences, carry water with you and tend the grass wherever you may be." – Robert Fulghum, author & essayist
Don’t waste time hoping for a better situation; make the best of wherever you find yourself and plan to be successful while you’re there using the resources you have. Whether you have performance goals of enhancing your physical fitness, becoming stronger mentally, bolstering your spirit, eating better, or enhancing your relationships, make sure that your “tools” are in good condition and ready to be used at any time. This can be particularly helpful if you (or your loved one) are on TDY or deployment because you can carry your performance-enhancement tools within you and employ them when needed.
For ways to sharpen your tools for Total Fitness (resilience and performance enhancement), check out the One Shot One Kill performance enhancement program to be prepared no matter where you are. Or if you have specific performance areas you want to strengthen, check out the other domains of HPRC’s website: Physical Fitness, Environment, Nutrition, Dietary Supplements, Family & Relationships, and Mind Tactics.
HPRC has received many questions about C4 Extreme and whether or not it will result in a positive drug test. We have posted an OPSS FAQ to answer the question. Be sure to check back often as we add answers to other questions about ingredients in performance and weight-loss supplements and how to choose supplements safely. If you have additional questions about a particular dietary supplement ingredient or product, please use our “Ask the Expert” button located on the OPSS home page.
Solid fats are solid at room temperature, come mainly from animal products, and are high in saturated or trans fats. Examples are butter, milk fat, cream, stick margarine, shortening, and beef, chicken, and pork fat. Some saturated fats increase blood cholesterol levels in the body. Oils are liquid at room temperature, and come from many different plants, and are good sources of heart healthy unsaturated fats. Examples are olive oil, canola oil, safflower oil, corn oil, soybean oil, and peanut oil. Coconut oil, palm oil, and palm kernel oil are high in saturated fats and are considered solid fats. When using fats, replacing solid fats with unsaturated oils will provide essential nutrients to the diet and help lower blood cholesterol levels.

According to a recent report about post-exercise recovery and regeneration for athletes, men over 19 and women over 18 needs 8-10 hours of sleep a night (plus a 30-minute afternoon nap, as needed) for optimal athletic performance.
Continuing good sleep habits established earlier in adolescence such as regular meals, early morning light exposure, and a nightly sleep routine remain important. However, it’s also important to monitor the effects of stress and changes in sleep due to training/military operations.
Even if you’re not an athlete, the recommendations above still apply, except that your total sleep needs are seven to nine hours a night to keep you at your best.
Some additional tips for sleep:
- Regular exercise during the day can help you sleep better at night.
- If you have a question about whether to exercise more or sleep, choose sleep!
- During the night, if you wake up and after 20 minutes haven’t gone back to sleep, get out of bed, do something relaxing, and then get back in bed. You’ll probably fall right asleep.
Also, for a better understanding of your current sleep habits, afterdeployment.org has an online “sleep assessment” that you can take. For more information on how to optimize your sleep, visit the HPRC’s Sleep Optimization section.
Don’t belong to a gym? Don’t own exercise equipment? Deployed with no workout facility close? On TDY? Only have a few minutes during commercial breaks of your favorite TV show to work out? No problem! We have the solution, whatever your excuse. These 25 at-home-exercises from the American Council on Exercise can be done anytime, anywhere. There are step-by-step instructions for each exercise, and all can be performed in a hotel, at home, at work, or in the middle of the desert. The only equipment you need for these exercises is you—so get started today!
Did you know that missing a night of sleep can produce performance results similar to those of being legally drunk? Even losing just a few hours of sleep can result in accidents and poor physical and mental performance. Sleepiness can inhibit balance, coordination, concentration, and response time—creating “the perfect storm” for accidents.
Make sure your sleep is optimal by turning off your electronics and other distractions well before bedtime, exercising during the day, avoiding caffeine late in the day, and sticking to a consistent sleep schedule. If you are in a situation where sleep is hard to come by, try to squeeze in naps when possible.
