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.
No single mental technique can do the job for you, just as no single tool is the only one in a construction project. You can’t hammer a nail with a wrench! HPRC offers nine rules and strategies for your mind’s toolbox to help you perform your best. Check out HPRC’s Performance Strategies on “Mental skills for optimal performance” to learn more.
The Food and Drug Administration (FDA) is warning consumers about powdered pure caffeine, particularly as sold in bulk on the Internet. At least one death has been associated with the use of such products, and FDA advises consumers about the potency of powdered pure caffeine. See FDA’s Consumer Advice, which includes information about how to report an adverse event.
According to this consumer resource from FDA, you should limit your caffeine intake to just 100–200 mg per day (about 5–10 ounces of coffee). Taking large doses of caffeine—roughly 400–500 mg—at one time can result in a serious condition known as “caffeine intoxication.” Some symptoms of caffeine intoxication are minor and include nausea, vomiting, agitation, nervousness, or headache. Other symptoms can be more life-threatening, such as rapid heartbeat, electrolyte imbalance, very high blood sugar, or high levels of acid in the blood, which can cause seizures. See the OPSS FAQ to help you avoid hidden sources of caffeine.
The term “mental toughness” is often tossed about, but what is it really? And do you have it? Mental toughness is important to the success of Warfighters, athletes, business people, and others who have to overcome adversity to be successful.
Sport psychologists and others interested in optimal performance talk a lot about mental toughness, but it’s a bit complex, so it’s often misunderstood. Mental toughness is not just one trait; it’s a mixture of them.
Boiling it down, mental toughness is a strong belief in yourself and an unshakable faith that you control your own destiny. If you’re mentally tough, you can remain undaunted by adversity.
If you have these 4 Cs, you’re mentally tough:
1) Control: You feel in control of your emotions and influential with the people in your life.
2) Commitment: You embrace difficulty rather than running from it.
3) Challenge: You believe that life is full of opportunities, not threats.
4) Confidence: You know you have what it takes to be successful.
Mental toughness is a psychological edge that some are born with and others develop. It allows you to consistently cope with training and lifestyle demands better than those who don’t have it.
You can develop mental toughness through a long-term process of developing mental skills. Leaders can promote mental toughness by creating a learning environment centered on the mastery of those skills (listed above) and by being generally supportive, encouraging Warfighters to maintain positive relationships. Over the long haul, to maintain your mental toughness, you need to continue honing mental skills, and you need a self-driven, insatiable desire to succeed.
Omega-3 fatty acids make up a family of polyunsaturated fatty acids. They are important to our health, and since our bodies can’t make them, we need to obtain them from the foods we eat. Omega-3 fatty acids may reduce the risk of heart disease and play an important role in our cell membranes. So, eating more can benefit the body in many ways.
The most widely available dietary source of EPA and DHA is cold-water oily fish such as salmon, herring, mackerel, anchovies, and sardines. Other oily fish such as tuna also contains omega-3 fatty acids but in lesser amounts. Some other sources of ALA are walnuts and canola, soybean, flaxseed/linseed, and olive oils. For additional information, including health benefits of omega-3 fatty acids, read this fact sheet; and for omega-3 content in various foods, try this infosheet from HPRC.
West Nile. Dengue. Malaria. Chikungunya. No, that’s not a typo. Chikungunya (pronounced “chik-en-gun-ye”), a mosquito-borne virus that primarily occurs in Africa, Asia, and the Indian subcontinent, and Warfighters deployed to these regions have been exposed to this risk for some time, now, however, it is reportedly spreading to Europe and the Americas. Most of the cases in the U.S. involve individuals who have recently traveled abroad, but the Centers for Disease Control and Prevention (CDC) just reported the first locally acquired case, in Florida.
The viral illness is characterized by fever and severe joint pain, but other symptoms include headache, muscle pain, joint swelling, and rash. There is currently no antiviral drug for Chikungunya, and treatment is aimed at relieving symptoms. Most patients will recover fully on their own, although sometimes symptoms persist for several months.
It’s important to know your environment. If you’re being deployed to these regions or even going there on vacation, there are things you can do to protect yourself from mosquito bites and mosquito-borne infections. Wearing long pants, shirts with long sleeves, and insect repellent while outdoors reduces the chance of an insect bite. Other precautions include removing standing water from containers such as flowerpots and buckets and placing screens over open windows and doors.
If you think you could have been infected, you should see your doctor, especially if you have recently traveled to high-risk regions. Visit the Center for Disease Control (CDC) for more information about Chikungunya.

Post-Traumatic Stress Disorder (PTSD) can tear apart your sense of what is safe and of what is good.
Part of the diagnosis of PTSD is exposure to a traumatic event: death, serious injury, sexual violence, or the threat of any of these. PTSD symptoms such as intrusive memories, avoidance of situations or feelings, problems in thinking or mood, and feeling overly amped up are common reactions to abnormal circumstances. Think of PTSD symptoms as self-preservation instincts gone haywire. One theory holds that, because you nearly died or experienced something awful or could picture it because it happened to someone close to you, your mind/body tries to sound the alarm bells to keep you safe. But the alarm bells sound at the wrong times and in the wrong ways.
However, PTSD symptoms can come from sources other than fear of bodily harm. They also can arise from inner conflict, when emotions trigger feelings such shame and guilt or when you question fundamental beliefs (such as “the world is basically good”). Witnessing or experiencing betrayal (especially by a leader in a high-stakes situation), within-ranks violence, extreme violence, and incidents involving civilians are some of what can disrupt your world view. It isn’t just an event but the interpretation of an event that causes Warfighters to experience “moral injury.”
If you suffer moral injury as part of PTSD, you start believing you live in an immoral world, or you view yourself as immoral, irredeemable, and defective. If you’re a Warfighter experiencing these feelings, you not only feel lousy, but you are more likely to isolate yourself just when you need others more than ever. Isolation can lead to self-handicapping or self-destructive behaviors.
So how do you save yourself from experiencing moral injury as a part of PTSD? Having a healthy sense of self-esteem can be one of your best protectors. There are no quick fixes. But forgiveness—of others and of yourself—can help you to let go of moral injury. With the help of a psychotherapist, you can begin to wrap your heart and mind around what happened. And pursuing positive interactions, such as getting involved with charitable groups, can give you opportunities to relearn that you are good and the other people in the world are generally good too. Last but not least, connecting with your spirituality—in whatever way is comfortable to you—can help you navigate this difficult journey.
Training for a marathon or some other endurance event? Building your endurance—by making the right nutrition choices—can make the difference between failure and success. HPRC’s performance nutrition strategies—“Going the distance”—provide the information you need to know what and when to eat for endurance.
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!
