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.
When you have to focus continuously for long periods of time, your brain does, in fact, become tired. Take a break: The symptoms of being mentally burned out can include irritability, lashing out at others, inability to plan, problems with decision-making, lack of drive, and performance errors. Mental fatigue can set in before you’re even aware you need a break, leading to the types of attention problems that ultimately lead to poor performance.
Mental fatigue can also include:
- Lack of clarity in your own head
- Conflict between what you’re thinking and what you are actually doing
- Feeling like you are in over your head
Mental fatigue can also make you feel tired physically, which is why it can be a greater risk for those who must sustain both focus and physical alertness. A brain busy with non-relevant matters also can be tied to feeling “spent.” You not only lose your mental edge and feel more exhausted, but you probably won’t push yourself physically as hard as you need to.
Fortunately, there are ways to combat mental fatigue. The best way is take a break and escape to a place you find relaxing or inspiring. However, if you’re in an office or on a mission, there are various mind-body strategies you can try. Mindfulness techniques are “mental push-ups” that strengthen as well as refresh your brain, so give them a try and give your brain a break.

Do you ever feel that you and your partner talk about the same issues over and over again? You’re not alone: Only 30% or so of the problems couples struggle with can actually be solved, leading to discussions that keep coming up about the other 70%. Solving the issues that can be solved is great, but learning how to interact in a positive manner about the “perpetual problems” is a good skill in any relationship.
One way to do this is to go through a structured problem-solving strategy such as this:
- Specifically state the issue.
- Briefly state why the issue is important.
- Brainstorm and discuss possible solutions to the issue.
- Have everyone involved agree on a realistic “solution”—even if it’s just a game plan for how each person is going to respond about the topic.
- Pick a specific amount of time to try the solution.
- Then give the solution a try.
Remember, the “solution” doesn’t have to mean a resolution to the problem; it can just be about new ways to approach the issue. For example, if you fight over one of you being late frequently, discuss ahead of time how you each would like the other person to respond. Maybe the latecomer needs to call or text if running late, or the punctual person calls ahead to find out if the other will be on time. And maybe you need to set a window of time rather than something exact.
November 11th is Veterans Day. HPRC would like to take this moment to thank each and every one of our Veterans and their family members who have so selflessly served our country. The VA describes Veteran’s Day as “a celebration to honor America’s veterans for their patriotism, love of country, and willingness to serve and sacrifice for the common good.”
Thank you to our Vets!
Whether you’re falling asleep or too “amped up,” you probably aren’t performing your best. Depending on who you are and what the task is, some middle ground is generally going to be best.
With simple tasks that require little conscious thinking, your reaction time is probably at its best around 60-70% of maximum heart rate (see HPRC’s article on aerobic conditioning), but response times for bigger bursts of movement improve if you’re more amped up. For example, you may be able to pull the trigger of your weapon fastest when you’re at 60-70%, but reaching for your weapon in the first place may be quickest if you’re at 90%. Keep in mind that this may not apply to more complicated tasks that involve rapid thinking, such as distinguishing a “friendly” from a “non-friendly” when someone is disguised.
There are two basic ways to get yourself amped up: physical activity and anxiety. Physical activity can happen through an intentional warm-up or even on its own because of the demands you are facing. If anything, you might find yourself needing to calm your body down. The same goes for anxiety. There’s the “butterflies-in-your-stomach” kind of anxiety and the more panicky “Darn! What do I do now?” kind. A little bit of the butterflies kind can be helpful, but again, it’s good to learn how to calm down and find middle ground!

Veterans who served in the U.S. and abroad between September 2001 and March 2010 were four times more likely than civilians to suffer from severe hearing loss. In fact, two of the most common disabilities affecting service members today are hearing loss and tinnitus, says the Hearing Center of Excellence (HCoE). Hearing loss and tinnitus seriously impact force readiness as well as the emotional and social well-being of those affected.
However, not all hearing loss results from the noise pollution Warfighters experience in the field. Many everyday exposures, such as your MP3 player or loud music in your car, can be just as damaging as firearms or helicopters. To maintain good hearing and operational readiness, Warfighters must use safe listening practices at all times. HCoE recommends these safe listening practices:
- Never listen to your MP3 player at maximum volume.
- Following the “60:60” rule: 60 percent maximum volume on your MP3 player for no more than 60 minutes a day.
- Take periodic breaks of 15–20 minutes when listening to loud music to allow your ears to recover.
- Select headphones or earbuds designed to remove background noise.
- Exercise caution when listening to music in the car. Listening in a confined space increases the risk of hearing damage.
- Wear hearing-protection devices such as earplugs at concerts, sporting events, parades, and other high-noise situations.
For more information on how to protect your hearing, as well as treatment and rehabilitation for hearing loss, please read this article from HPRC and visit HCoE.
You may not think about your feet much, but you should. The condition of your feet can make or break a ruck march, hike, or any other physical activity, especially ones that involve wearing boots. There are easy steps you can take to keep your feet blister-free, fungus-free, and in optimal shape for the many demands you put on them. Take a few minutes to self-examine your feet for any obvious problems. Military OneSource offers great advice on foot hygiene and the correct use of socks and boots. Something as simple as tying your boots correctly can prevent foot problems down the road!
HPRC wishes you a very Happy Halloween! Halloween can be a fun family holiday, with costumes, trick-or-treating, parties, and food. But before you jump all in, review some safety tips to keep this holiday fun and safe! The Centers for Disease Control and Prevention highlights some tips: Don’t trick or treat alone or stop at dark houses and do wear reflective tape, examine all candy for evidence of tampering, avoid homemade treats, and use a flashlight.

Making it into a Special Operations Force (SOF) is challenging, to say the least; it requires intense physical and mental stamina. A keynote presentation at the 2013 Association for Applied Sport Psychology Conference highlighted what it takes to be an SOF “Tactical Athlete.” It focused on the ability to “embrace the ‘suck’” (grueling experiences) and remain alert during periods of extreme discomfort—hot, cold, wet, or dry—along with heavy gear, noise, and fatigue.
Unlike most athletes, there is no “season,” so SOFs are required to always be on. This means intense training is part of the SOF experience—a selection process where “survival of the fittest” is the rule. Some of the physical characteristics that can help a person withstand the training are endurance, strength, coordination, and flexibility. Those selected to be SOF personnel also tend to possess the following mental characteristics:
- Above-average IQ: Most are brighter than most other people, and those of average intelligence optimize what they have.
- Complex reasoning: They can grasp and reason through abstract concepts.
- Tolerance of ambiguity: SOFs accept when they are not in control and do their best under those circumstances.
- Situational awareness: They can usually remain aware of their surroundings while tuning into what is most relevant.
- Good decision-making: They have good judgment, even in uncomfortable conditions.
- Mental flexibility: SOFs are able to adapt rather than get stuck on certain beliefs.
And in terms of personality, SOFs generally are:
- Emotionally stable: They do not usually experience extreme highs or lows.
- Stress-tolerant: SOFs accept and cope with stress rather than try to escape it.
- In control of their behavior: They act in accordance with their values, keeping their creed in mind.
- Self-confident: They are not consumed with self-doubt or rigidly confined by other people’s rules but possess their own strong moral compass.
- In control of aggression: SOFs are able to use their aggression in a targeted manner.
- Self-reliant: While they can work well with a team, they are also highly independent.
- Motivated: SOFs tend to have a very strong work ethic.
Finally, success with SOF training begins in part with an attitude. Anyone who yearns to be an SOF must above all cultivate an ability to turn attention outwards amidst “the suck.” Grueling conditions become a cue to remember that your comrades are also hurting and that each of you depends on the others to work hard. Taken together, SOFs embrace their membership in this elite group as an identity.
