Welcome to the HPRC Blog. We've got lots of information here, from quick tips to in-depth posts about detailed human performance optimization topics.
The smallest acts of kindness and caring can have powerful results for kids of all ages. With everyone so busy juggling multiple responsibilities—especially military families—it can sometimes feel as if there’s never enough time to have meaningful connections with children. But kids still need those moments. A meaningful connection can be a hug, a smile, a loving word, a compliment, or just giving them your undivided attention for a few minutes to listen to a story they are telling, to sing a song, or dance together. Feeling loved in these small moments stays with a child his or her entire life. This New Year, set an intention to make a meaningful connection with any child(ren) in your life regularly. And remember: Adults also benefit from heartfelt connections. Hug your loved ones today.
The holidays are often a flurry of festivities, a time when we interact with more people than usual while at the same time feeling more stressed than usual. When you feel stress, often one of the first outward signs is how you communicate with others. Watch for an edgy tone to your voice and notice if you stop using a lot of eye contact with people who are talking to you. You may even start forgetting what someone just said. These are common signs of stress. This holiday season, go back to the basics: When someone is talking to you, use eye contact; when someone asks you to do something, repeat it back (it’ll help you remember); and think about your tone of voice and body posture (think open and non-defensive). But if you do slip up from time to time, own up to it, ask for forgiveness, have a good laugh, and focus on moving forward and looking at the bright side.
It’s officially “holiday season,” and maintaining your fitness can be a challenge. You might find yourself socializing and eating more, with less time (and motivation) to exercise. Get your workout routine into the holiday spirit too—without having to sacrifice a lot of time.
- Take the Guard Your Health Fitmas Challenge! Each day for twelve days, commit to doing one of these exercises.
- Try interval training with this high-intensity workout from the American College of Sports Medicine, which requires little or no equipment.
- Make workouts social by getting your friends and family involved.
Different people react differently to stress, especially when it comes to food, and depending on the cause, intensity, and duration of stress. Whereas some people lose their appetite and skip meals in response to stress, others either overeat or eat unhealthy foods. Under stress, people tend to choose snack-type foods that are high in fat and sugar instead of meal-type foods such as meats, fruits, and vegetables.
Stress isn’t necessarily a bad thing. In fact, it’s essential to survival and part of being a Warfighter. The key is learning how to manage your stress. December is the Military Health System’s Stress Management Month, which is especially appropriate for most of us during the holiday season. Here are some tips to help you reduce your stress and the likelihood of overeating:
- Engage in physical activity most days of the week, and try stress-relieving exercises such as yoga and meditation. Or find other hobbies that you enjoy and that help you feel relaxed.
- If you’re finding it difficult to stop reaching for the kitchen cupboard or refrigerator, make sure you stock your shelves with healthy snacks such as fresh fruit, cut-up veggie sticks, and air-popped popcorn (without the butter).
- Try to keep a food diary to understand the connection between your mood and your food. Keep track of what you eat, when you eat, and your emotions at the times you want to eat.
Learning how to manage your stress can be beneficial in more ways than one. For more information on stress and your health, read the National Institute of Mental Health’s factsheet on adult stress and HPRC’s resources for stress management.
That mental state dubbed “the zone” by the media is what scientists call “flow.” It happens when you perform at your best easily because you’re performing automatically, without overthinking, focusing only on what’s happening right now.
To help yourself perform better more consistently and possibly even experience flow, consider these typical blocks and how to overcome them:
- Personal demands: It’s hard to focus on the task at hand when there’s personal stuff on your brain. Do what you can in advance, and shift to the present moment with self-talk such as “focus.”
- Mission complexity and ambiguity: If it feels as if there are too many “moving parts” in a task, try to gain clarity up front. Ask questions and use mental imagery to see in your mind’s eye what needs to be done.
- Interpersonal conflict: Everyone replays arguments mentally. Resolve them at the front end or put them on hold during a mission. Routines can help you bring your attention to the here and now.
- Paralysis by analysis: Thinking too hard is another way that people sometimes get stuck. Trust your training and let your best performances unfold.
- Limited control or resources: Deciding what is in your control and what isn’t can help you focus on what’s most important in the present moment.
- Isolation: We all need other people. Be active in seeking support.
- Intense workload: If anxiety about what’s in front of you is getting in the way, try embracing excitement about whatever you’re facing.
- Boredom or underutilization: When you know you need more challenge, ask for it.
Big demands require big resources. Overcome mental blocks to performance by continuing to develop your mental resources.
Lately, HPRC has been receiving a lot of questions about the use of banned supplements in the military, but the fact is: There isn’t a list of banned dietary supplements currently available. It isn’t always easy to determine whether a dietary supplement product is safe or not, so the Department of Defense (DoD), together with HPRC, provides helpful resources on the Operation Supplement Safety (OPSS) website to help you choose supplements wisely. With regard to the military’s stance on supplements in general, please see the OPSS FAQ about a "banned list," which is pertinent to all service branches.
Some dietary supplements, including ones sold on military installations, contain potentially harmful and problematic ingredients. For some tips about how to avoid these, read the OPSS infosheet “Red Flags—What You Need to Know.” In addition, some other potentially dangerous ingredients include prescription drug ingredients and their analogs, drugs banned by FDA for safety reasons, controlled substances (such as anabolic steroids), and untested/unstudied new active drug ingredients, which may not be listed on the product label.
One way to ensure that a dietary supplement product is safe is to see if it is third-party verified. Third-party certification organizations have developed criteria for evaluating and authenticating the quality of a supplement—the ingredients, the dosage levels, the level of contaminants, the label claims, and whether the manufacturing facilities follow Good Manufacturing Practices (GMP).
The Natural Medicines Comprehensive Database (NMCD) is the gold standard for evidence-based information on dietary supplement products and ingredients and is an HPRC partner. (Subscription is free if you have a “.mil” email address; visit the OPSS FAQ for more information.) NMCD rates products on a scale of 1 to 10 based on safety and effectiveness. We encourage you to consider only using products rated 8 or above.
To avoid potential problems, talk with your healthcare provider or dietitian before using dietary supplements. Also, see FDA’s list of tainted bodybuilding products, which includes important public notifications.
Many of us have the habit of focusing on the negatives in life and expecting the worst outcome. This tendency can be compounded by military training that teaches you how to assess risks and plan for the worst outcome. If you tend to focus on the negatives in life, you’re shortchanging yourself. Try to appreciate the little things in your day that you may take for granted. Focus on appreciation and gratitude. Try breaking your habit of focusing on the negative for just one day; instead spend it acknowledging and appreciating the ordinary good things in your life.
- When you wake up in the morning, stop and take a moment to say good morning to your day.
- If you are in a relationship, take a few minutes to really look at and appreciate your significant other.
- If you are deployed with your unit, pause to think about how your buddies support and help one another to get through a rough day.
- Before you eat lunch, reflect for a moment and think about something that keeps you going everyday—maybe it’s as simple as the first cup of coffee in the morning, an easy commute, or your buddy’s positive attitude. Take a moment to be grateful for that.
- At dinner, spend a moment thinking about your loved ones. Have you told them lately something you appreciate about them?
- Finally, before you go to sleep, acknowledge something about yourself you’re proud of.
Start again tomorrow, reflecting back to today—did acknowledging the magic of the “everyday” help you have a better day?

Is it safe to exercise when I’m sick? This is a common question, especially from people who have strict workout schedules and aren’t likely to let the sniffles get in the way of their physical fitness. Benefits of exercise include weight control, improved mood, more energy, and better sleep. What’s more, just 30 minutes of regular exercise three or four times per week can boost your immune system and improve overall health, helping to keep those colds at bay.
Moderate exercise while you’re sick can be safe and in certain cases may actually improve symptoms (such as relieving congestion and increasing energy). But first you need to determine “how sick is sick.” You can figure this out by using the “neck rule.” If you have symptoms above the neck—including sore throat, nasal congestion, sneezing, or watery eyes—then moderate workouts can continue. If symptoms are below the neck—including cough, fever, fatigue, or body aches—then rest is in order until the symptoms are gone. You can also use your temperature to determine whether exercising is okay. If you have a temperature of 101°F or higher, moderate or vigorous exercise is not wise because of the risk of heat-related illnesses and dehydration.
Ultimately, the decision to exercise when you’re sick is up to you. If you’re too weak and fatigued to get out of bed, exercising may not be the best thing to do at that time. However, if you have symptoms of a cold and your temperature is below 101°F, light to moderate exercise may be beneficial. You should consider seeing a doctor if your symptoms don’t improve or get worse.
Intermittent fasting has become a popular strategy for weight loss. “Fasting” can mean different things—from fasting as much as 16 hours per day to skipping or restricting caloric intake (for example, to less than 500–600 calories) one or two days a week. Fasting programs may make promises to their followers to lose weight and improve health, but are they safe and effective?
The health benefits claimed for intermittent fasting have mostly come from studies with animals. A few small studies with humans have shown intermittent fasting—eating as usual five days a week and eating 25% less two days per week—may be useful for weight loss. Because these studies were short term, however, the long-term safety and effectiveness of intermittent fasting are unknown.
In addition, it is unclear if intermittent fasting is more effective for weight loss than just eating less on a daily basis. Intermittent fasting could lead to overeating on non-fasting days, and even advocates of intermittent fasting point out that the key to weight-loss success is not to overeat on “normal” eating days.
Eating too few calories over time can result in low levels of vitamins, minerals, or other nutrients, and even the loss of muscle mass. And intermittent fasting can be dangerous for people with medical conditions such as pregnancy, diabetes, or eating disorders.
Common side effects of fasting include lack of energy, headaches, feeling cold, and constipation. Fasting can cause low blood sugar if you aren’t getting enough fuel to your brain, reducing your ability to concentrate and focus and affecting your sleep cycle and mood. These effects can interfere with your body’s ability to perform optimally.
Athletes who fast during Ramadan—a holy month when Muslims are expected to fast daily (no food or water) from pre-dawn prayer to post-sunset—provide some insights into the effects of fasting on performance. The limited intake of carbohydrates, protein, and fluid during fasting days sometimes affects their bodies’ ability to recover from exercise. Some found that their cognitive performance suffered as well due to the effects of even mild dehydration and inadequate carbohydrate intake. Exercise that is both physically and mentally challenging and long-lasting could have even greater negative effects.
Intermittent fasting may be unrealistic for long-term use. Reducing your overall caloric intake and a regular exercise program are the best combination for weight loss.
For some injured Warfighters, achieving total fitness may include assistive technology (AT). Assistive technology is any physical equipment or system used to improve or help maintain the functional abilities of an individual. There are assistive technologies for almost every disability or injury, such as communication boards, both manual and electronic; technology for vision and hearing impairments (magnifiers, talking watches, hearing aids); tools to assist daily tasks (shower chair, adapted eating utensils); adaptive sports equipment (sit-skis, sport wheelchairs, recumbent tricycles); and technologies that enable mobility (from a cane or walker to sophisticated prosthetic legs and powered wheelchairs). Driving aids and fully equipped vans are other important assistive mobile technologies. Mobile assistive technology can promote independence and increased quality of life. Even phones and apps can be used as memory aids and organization- and time-management tools for helping with traumatic brain injury and psychological health. If you’re an injured Warfighter looking at the possibility of AT (or if you just want to know more), there are many things to consider when choosing the right AT for you, including:
- First and foremost, understand your own goals, priorities, and preferences and discuss them with your healthcare team. A person’s reaction to AT is both personal and complex. You must be closely involved in the choice of your assistive technology to ensure a “good match.”
- Consider where you will be using your assistive technology (indoors or outdoors).
- Consider how you will feel about using your equipment. AT equipment shouldn’t be embarrassing, inconvenient, or cumbersome.
- Have you accepted your challenge, and are you ready to move forward? Finding a "new normal" to accomplish your goals may include using assistive technology, but you must first embrace this concept.
For those who can benefit, AT can be a big piece of Human Performance Optimization (HPO), part of HPRC’s Total Force Fitness mission.
