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.
Noticing whether your hands and feet are running hot or cold is one way to tune in to how stressed or relaxed you are. They’re also useful indicators to change—with the power of your mind—those feelings of stress.
There are many stress-reduction techniques to choose from. Here’s the simplest tool there is: Put on some relaxing music. Choose music that has repetitive rhythms, predictable patterns, a low pitch, and no vocals or percussion. This kind of music can help manage anxiety and pain, change brain activity, and increase skin temperature (similar to the hand-warming technique called autogenic training).
Combining approaches to stress reduction can also help. With this in mind (and simply because it sounds good), HPRC tweaked the autogenic training MP3 that we released earlier by adding music to the beginning and end. It’s a minor change, but we hope it will enhance your autogenic training experience.
Achieving and maintaining a healthy weight can be a challenge, especially when trying to juggle the demands of active-duty service, deployments, family, and life in general. Knowing that the next weigh-in is looming can be stressful and can sometimes lead to eating behaviors that spin out of control to become a life-threatening eating disorder. But even if you don’t have a classic eating disorder, you might have what is called “disordered eating.”
“Disordered eating” refers to eating foods or having eating patterns that can lead to serious nutritional consequences such as deficiencies in key nutrients and electrolytes. It can compromise a person’s strength and/or stamina and lead to more frequent illness or injury. This could happen to a Warfighter, spouse, child, or other family member.
Examples of disordered eating include emotional eating, binge eating, night eating, highly restrictive dietary patterns, and avoiding foods considered “bad.” Some individuals use over-the counter products such as weight-loss supplements or laxatives; others participate in excessive exercise as a means to control weight. What starts out as a way to lose a few pounds or tone up could become a serious problem.
If you’re wondering if you practice disordered eating, ask yourself these questions:
- Do you eat in secret?
- Are you terrified of gaining weight?
- Are you always counting calories/carbs/fat grams or some other component of food?
- Do you think your identity and self-worth depend upon your weight and body shape?
- Do you exercise a lot (maybe too much) to maintain your weight or appearance?
If you answered "yes" to any of these questions, you might have disordered eating. It’s important to get help before your problem becomes more serious than you can handle. Nutritional and emotional counseling from professionals—registered dietitians, counselors, and therapists—can help. Support from friends and family is important too. See the Academy of Nutrition and Dietetics for more information on disordered eating.
Roughly one in five teens is bullied at some point. It often involves hitting, pushing, or teasing, but gossip (both verbal and text) and being excluded are also forms of bullying.
The reasons for teen aggression are complex, but some school and home factors raise the chance of a teen being aggressive: rejection by peers, situations where aggression is socially acceptable, marital conflict and violence at home, feeling rejected by a parent, physical punishment by a parent, and/or parents who let their teens get away with any kind of behavior.
Since teens are still learning how to manage their emotions, aggressive behavior is a clue that they need more skills in this arena. Aggressive teens also are more likely to have problems at school that can follow them to adulthood, so it’s important to find solutions early. And of course, the victims of bullying suffer too.
Parents, schools, and communities can help stop aggressive behavior. Parents can reduce their teens’ exposure to aggression at home by controlling their own anger and outside the home by knowing where their teens are, who they’re with, and setting clear expectations for how to act when parents aren’t around. Teachers can learn to recognize aggression, communicate that it is unacceptable, and seek help/intervene. Schools can monitor areas where aggression is most likely to occur, such as playgrounds, restrooms, and hallways.
Stopbullying.gov (a website developed by the U.S. Department of Health and Human Services) offers lots of ideas for how to respond to bullying: Respond quickly and immediately to bullying behavior, find out what happened, and support the kids involved (both the bullies and those being bullied). In essence, don’t be a bystander. To learn more, visit this interactive page. The bottom line is that bullying is not acceptable, but it won’t stop unless you do something about it.
What are omega-7 fatty acids? And do omega-7 supplements convey the health benefits advertised?
Omega-7 fatty acids are a type of unsaturated fat. Omega-7s are considered non-essential fatty acids, which means your body can make enough omega-7s to function properly. In other words, you don’t need to get them from foods or supplements.
One of the most common forms of omega-7s, which is also used in supplements, is palmitoleic acid (not to be confused with palmitic acid, which is a saturated fat). Omega-7 supplements are marketed for health benefits such as heart and liver health, improved cholesterol levels, weight loss, glucose (blood sugar) metabolism, and immune support. Limited research has shown some benefits from palmitoleic acid supplementation, but most of the research has been done on animals and only for short test periods (less than four weeks). As a result, no recommended dose or source of palmitoleic acid exists, and there is not enough evidence to suggest that omega-7 supplements can improve heart health or health in general.
HPRC previously ran an Injury Prevention series with some general information to help keep you off profile. A new addition to the series is Injury Prevention Strategies, which will include information for the knees (specifically the anterior cruciate ligament or ACL), ankles, shoulders, and back. Check back often for the next in the series, and keep your body functioning at the top of its game!
You probably know that fruit, vegetables, and olive oil are healthy foods for your heart, but what about chocolate? For hundreds of years, chocolate—more specifically cacao, the unprocessed cocoa bean—has been considered good for health.
Cocoa is in high in flavanols, plant compounds with antioxidant activity that can help prevent or delay damage caused by free radicals. These antioxidant-rich flavanols are linked to reducing the risk of cardiovascular disease. Some evidence has shown that cocoa can help lower blood pressure, LDL (“bad”) cholesterol and improve blood flow.
However, not all chocolate is created equal. In general, the less processing, the more flavanols. Pure, unprocessed cocoa has more flavanols than chocolate, which has sugar, fat, and other additives. Dark chocolate has more flavanols than milk chocolate and white chocolate. But eating enough chocolate products to reach the desired amount of flavanols could require hundreds or even thousands of calories. While all that chocolate may taste great, the extra sugar, fat, and calories are not heart healthy.
Enjoy a square of dark chocolate or a serving of cocoa as part of your day, but the jury’s still out on whether chocolate can really help your heart.
Nootropics—also referred to as “cognitive enhancers,” “smart drugs,” or “memory enhancers”—are substances intended to improve mental performance. They include drugs used to treat a variety of conditions that affect mental performance such as Alzheimer’s disease, dementia, epilepsy, schizophrenia, stroke, aging, and attention deficit hyperactivity disorder (ADHD). For example, drugs in the racetam family—such as piracetam, aniracetam, oxiracetam, and pramiracetam —are considered nootropics. Some nootropics are marketed for use as dietary supplements to enhance the mental performance of healthy humans.
Nootropic products that contain any “racetam” or similar drugs are not legal dietary supplements as defined by the Food and Drug Administration (FDA), although many also contain vitamins and other natural or synthetic dietary supplement ingredients. In the U.S., piracetam, aniracetam, pramiracetam, and oxiracetam are currently neither controlled substances nor FDA-approved drugs. FDA has issued statements indicating that piracetam-containing “dietary supplement” products do not fit the legal definition of a dietary supplement, since “racetams” do not occur naturally and are not derivatives of any natural substance.
Although scientific study of nootropics is ongoing, there isn’t enough reliable information available to say with confidence whether any specific nootropic agents are safe or effective. Studies that have examined the effects of these compounds on the mental performance of healthy humans have yielded mixed results, so further study is needed. In the absence of reliable research, we generally suggest extreme caution.

Not everyone is affected the same way by exposure to injury and death. Many who do experience psychological wounds, however, come out stronger as a consequence, and so can you. If you’ve experience a traumatic event or experiences, there can be an upside: It’s called “post-traumatic growth” or PTG. It’s about finding a “new normal” that is even better than how things used to be. PTG can mean better relationships, openness to new possibilities, personal strength, spiritual change, or heightened appreciation of life. In addition (and researchers are still trying to understand why), if you get PTSD, you’re actually more likely to experience PTG. Nobody wants to experience PTSD, but if it happens, you may have an amazing opportunity to come out the other side with some unique strengths.
Relationships are important to total fitness—especially intimate relationships. Think back to the beginning of your relationship—was it filled with lots of passion and intensity? Does it still have those aspects?
There’s been a lot written about the different types of romantic love, and how they change over time. One theory describes two main types of love: passionate and companionate. Passionate love involves an intense feeling of longing for one another. Companionate love happens when you feel affection, tenderness, intimacy, and commitment to your partner. Couples with companionate love often also feel a deep mutual friendship, an ease of companionship and a sharing of common interests. Companionate love does not have to include being attracted to each other or sexual desire.
It’s generally thought that couples begin in passionate love and later morph into companionate love. However, research suggests that romantic love that has intensity, interest, and passion can grow and flourish in relationships over the long run. As with diet and physical fitness, moderation is key. Focus (but don’t fixate) on your partner and foster affection, intimacy (both physical and emotional), and a deep bond. It is possible to be with your partner for a long time—and still experience passion and emotional intimacy with him or her! So set the bar high and strive for it. It is not a myth!
Heart disease is the #1 cause of death among women (and men) in the United States; deadlier than any form of cancer. Risk factors for heart disease include high blood pressure, high cholesterol, diabetes, overweight/obesity, family history, and smoking.
So what can you do to protect yourself and the women in your life? First, know your risk factors. There are some things that you can’t change, such as your family history and your age. However, you can reduce your risk through lifestyle changes.
Regular exercise can help you manage many risk factors such as weight, blood pressure, and cholesterol. By now, you have probably forgotten about your New Year’s fitness resolutions! Get back on track: Commit to at least 30 minutes of moderate to vigorous activity at least four days of the week and stand up for your health.
