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.
Do you know how much sleep you and your loved ones are getting—and supposed to be getting? Keep in mind the recommendations differ by age group. According to a report from Canadian Sport for Life on optimal sleep for athletic performance at all life stages:
- Children under the age of six need 13–16 hours of sleep daily, including longer nighttime sleep and fewer daytime naps as they get older.
- As girls reach the ages of 6–8 and boys reach 6–9, their sleep needs drop to 10–11 hours of sleep a night.
- Girls 8–11 and boys 9–12 need 9 ½ to 10 hours of sleep a night.
- Girls 11–15 and boys 12–16 need around nine hours of sleep a night.
- In addition to their nightly sleep, girls 6-15 and boys 6-16 need a 30-minute-plus nap between 2–4 pm every day.
For young children, meals—particularly breakfast—are an important part of establishing a reliable sleep routine, and as children age they should start developing a 15–30 minute routine before bedtime to get ready physically for sleep. This is also a great opportunity for some quality time between parents and children that you can all look forward to each night.
To make this goal easier, be sure your kids avoid computers and TVs (anything with electronic stimulation) for one to two hours before bedtime. Allow an hour to unwind before bed—try soothing music, reading, and dim lighting.
As children become teenagers, make sure they don’t start incurring a sleep debt by sleeping less than needed. Encourage them to keep regular sleep hours, get early morning light exposure, and carefully gauge their caffeine consumption close to bedtime.
The report mentioned above suggests using a sleep log (and provides a sample log) to get an idea of your and your child’s sleep patterns. Remember that the warrior athletes of tomorrow need to develop good sleep habits today!
A Military Times article reports on a recent study of more than 30 of the most popular dietary supplements (in capsule form) sold on military bases analyzed to determine their caffeine content. Of the 20 supplements that listed caffeine as an ingredient on their labels, six did not specify the amount. These same six contained high amounts of caffeine (210-310 mg per serving)—three or more times the amount permitted by law in soft drinks. Five others revealed significantly different amounts—some more, some less—than the quantity stated on the product label.
Consuming too much caffeine can result in health issues. And if you don’t know how much is in the supplement you’re taking, it could be easy to overdo it if you also drink coffee or energy drinks. Visit the Operation Supplement Safety (OPSS) FAQ on caffeine for additional information.
Many jobs involve duties that can cause minor musculoskeletal tension that builds over time until you find yourself experiencing pain. Sitting or standing for long periods of time, lifting or carrying heavy objects, and other common mission-related actions of active-duty personnel wear on the body, leading to increased risk for injury. Yoga can help to reduce this risk by improving posture, increasing energy, and stretching overused or tense muscles. If you don’t have time for yoga between work, your normal exercise routine, or family obligations, suggest sharing a quick yoga session with buddies in your unit during a break to reduce your risk for injury and help get through the afternoon. There are different styles of yoga for all skill levels.
The way you interpret what other people say and do affects your performance as a Warfighter. Sometimes you may interpret things in faulty or unproductive ways called “thinking traps.” They can significantly damage your ability to reach your full potential. However, there are methods you can learn and use to develop alternate thoughts that promote productive and positive thoughts—a process is called “cognitive reframing”—that will lead to optimum performance. Learn about how to do it in HPRC’s Performance Strategy on how to “Reframe your ‘thinking traps’ for peak performance.”
Do you show your loved one appreciation? Gratitude is an essential element in happy relationships. Couples who feel appreciated by their significant others in turn are more appreciative back to the other person. Also, when shown appreciation, people tend to be more responsive to their significant other’s needs. In short, gratitude is contagious! Try it. When you next talk to your significant other, find something to be appreciative about and see if it has any positive ripple effects. This can also help maintain intimacy when you are apart from your loved one due to deployment or TDY.
Virtual reality was first introduced as a therapy tool for people with anxiety disorders such as phobias, but it is now used for a wide range of conditions, from PTSD to childhood ADHD. In fact, it recently warranted its own symposium at Walter Reed National Military Medical Center, where experts exchanged ideas on the current state of research.
Virtual environments used in therapy sessions are created for the individual’s needs—for example, a noisy classroom for a child with ADHD, the re-creation of the 9/11 attacks for a firefighter or police officer, or “Virtual Iraq” for a soldier. “Virtual Afghanistan” is the newest creation and is already being used to help service members overcome PTSD. Active-duty men and women are gradually brought back to their traumatic event using the virtual world as the therapist provides verbal cues to facilitate the healing process.
With a view to mitigating future need for therapy, a series of episodes is currently being created to provide pre-deployment “Stress Resilience Training for Warfighters.” The goal is to help reduce the risk of PTSD and better prepare warriors for actual scenarios they will encounter in theater.

Preventing obesity should begin at an early age, because children who are overweight often become obese as adults. And while many of us know that we need to eat right and exercise, there are also risk factors that we are born with that we can’t change. Now you can calculate your child’s risk of developing obesity with an online calculator.
The calculator was developed by a team of researchers who looked at a number of well-known biological and social risk factors for developing obesity. They were able to boil down their findings to six simple factors that provide a reasonably accurate probability of whether a child will develop obesity:
1) The body mass indexes (BMIs) of both parents. (HPRC has a link to a calculator you can use to calculate BMI.)
2) The number of people who live in the house.
3) What kind of work the child’s mother does.
4) Whether the mother smoked during her pregnancy.
5) The birth weight of the child (in kilograms). (To convert pounds [lb] to kilograms [kg], multiply pounds by 0.45359237.)
Living a healthy lifestyle is beneficial for everyone, but tools like this can help you determine whether your child is particularly at risk for becoming an obese adult, so that you can make important health changes early in life.

Lugging around heavy weights and other exercise equipment while traveling or on deployment isn’t the most practical idea. Pack a couple of suspension-training straps, however, and you’ve got part of a well-rounded training routine covered. Suspension training has gained a lot of popularity among both civilians and service members alike, and more and more gyms are now offering suspension-training classes. Once the straps are securely anchored to something that won’t move and is sturdy enough to hold your weight, place your hands or feet into the loops, and your body weight enhances the effectiveness of exercises such as push-ups, lunges, core strengthening, and more. While there are various ways to adjust and adapt the exercises for less experienced exercisers, this type of workout requires some initial joint and core stability. There is also potential risk of injury, especially for beginners. Before you try this for the first time, it’s a good idea to get some advice and guidance from a suspension-training professional.
The physical and emotional stress associated with post-traumatic stress disorder (PTSD) can raise your blood pressure and cholesterol and increase body mass index, all of which are risk factors for heart disease. Veterans suffering from PTSD are more than twice as likely to die from a heart attack than those without PTSD. While the exact relationship between PTSD and heart disease is not fully understood, we know that regular exercise can help prevent heart disease and other risk factors, which could be helpful for those with PTSD. Some types of exercise can be effective in reducing psychological symptoms associated with PTSD and also can play a role in reducing unhealthy behaviors such as smoking, being overweight, and physical inactivity—sometimes byproducts of trying to cope. If you think that exercise might help you or a loved one cope with PTSD, speak with your healthcare provider to assess how much and what kind of exercise is best!
At some point or another, your child or teen might pick up those dumbbells you have lying around the house. They’ve seen you lift weights as part of your regular exercise routine and decided they want to get stronger too. But you might wonder if strength training is safe for your kids.
Lifting the size weights you use might be too much for kids and teens, but in general strength training (also referred to as resistance training) can be a safe and healthy way to improve muscular fitness for children and teens, starting as early as seven or eight years old, when their coordination skills have developed enough. The goal should be improving muscular fitness while having fun and learning effective training methods.
As a parent you need to make sure your kids are supervised and receiving age-appropriate and skilled instructions in order to reduce the risk of injury. With proper technique and safe practices, strength training is not dangerous for growing bodies. However, light weights, exercise bands, or your child’s own body weight should be used to build his or her strength. Currently, there are no specific guidelines for exactly how much lifting they should do. However, according to the American College of Sports Medicine (ACSM) one to three sets of six to 15 repetitions, two to three times per week is considered reasonable.
Resistance training is not the same as bodybuilding, weightlifting, or powerlifting, which are associated with competition, high intensity, and maximum weights. The American Academy of Pediatrics and ACSM are opposed to children using these methods or the use of "one-rep-max" (a method sometimes used to assess strength) due to the increased risk for injury.
While a medical examination is not mandatory, it is recommended for children who want to begin a strength-training program. And remember that strength training is something you can do with your children. Family fitness is a great way to keep you and your child healthy and active while you spend quality time together.
