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.
March 6–12 marks National Consumer Protection Week, a campaign that encourages consumers to make informed decisions about the products and services they purchase and avoid getting caught in a scam. Dietary supplements are often marketed with claims that sound too good to be true, so be a savvy consumer and question claims such as “quick fix,” “miracle cure,” and “scientific breakthrough.” If you find a product you believe is falsely advertised/labeled or caused an adverse reaction, report it.
Visit the National Consumer Protection Week website to learn more about how to protect yourself from fraud, not just this week, but every day of the year. Operation Supplement Safety (OPSS) strives to provide the best resources and tools to help you choose supplements wisely. You’ll find even more information and consumer updates about dietary supplements from federal agencies such as the Food and Drug Administration and the Federal Trade Commission, and watch this video from Attorney General Loretta E. Lynch.
When there’s consensus among family members about your military service, life is much easier. It’s normal for loved ones to have differing views about service and/or levels of commitment over time. But when there’s a big difference, some families might feel an extra burden of stress or sadness. Here are some tips to help build a bridge to family harmony. Read more here.
Between the growing epidemic of childhood obesity and the continuing popularity of video games among children, does exergaming actually count as physical activity? Exergaming, or exercise video gaming, is popular among children and adults because it offers entertainment and physical activity. Exergames include:
- Virtual cycling
- Interactive climbing machines
- Aerobics, dancing, and floor games for multiple video game platforms
- Mobile exercise games for smartphones and tablets
While it’s certainly fun, studies suggest that exergaming is not the best form of exercise for kids. It does increase energy expenditure (compared to rest), but it’s not necessarily enough to meet your children’s exercise needs. For example, when compared to a phys ed class, exergaming fell short. For the most part, kids who play exergames don’t burn enough calories or increase their heart rates enough to make up for exercising.
The good news about exergaming is that it can increase motivation and keep children engaged. It could be a great starting point for inactive children needing to begin a physical activity routine. It can be part of the daily-recommended doses of exercise and physical activity for kids and teens too. Families could find it as a fun alternative to sitting on the couch and watching a movie or TV show. Exergaming might be better than sitting and playing video games, but it shouldn’t replace more vigorous activities such as outside play. Save the exergaming for the next rainy or snowy day!
March is National Nutrition Month® and the Academy of Nutrition and Dietetics is encouraging everyone to enjoy different food traditions and celebrate the role that food brings to their lives. This year’s theme, “Savor the Flavor of Eating Right,” points out that the how, where, when, and why are just as important as what you eat. Making sure to enjoy the sights, sounds, memories, and interactions associated with eating are essential. Slowing down and taking time to appreciate the positive emotions that accompany mealtime are also important steps to developing a sustainable healthy-eating plan. Developing an eating pattern that includes nutritious and flavorful foods is the best way to savor the flavor of eating!
Every March, the Academy sponsors its month-long nutrition education campaign to share its message that improving overall well-being requires a lifelong commitment to healthful lifestyle behaviors, including nutritious eating practices and regular physical activity. Be sure to visit the Academy's website and check out its resources on food, health, fitness, and more.
Many service members exposed to bomb blasts in the field walk away unscathed—or so it would seem. However, there could be some damage they’re not “seeing.”
High-pressure shockwaves from explosive blasts can cause serious eye trauma. In fact, up to 10% of all blast survivors experience significant eye injuries from projectiles thrown into their eyes, eye perforations caused by the high-pressure blast waves, or effects on the eyes associated with traumatic brain injury (TBI). If you were exposed to a blast while in the field but weren’t otherwise injured, don’t wait to set up an appointment with your eye doctor. Prompt medical attention could prevent permanent injury.
Most eye injuries are preventable if you wear protective eyewear on-duty and off-duty. There are many options to choose from the Department of Defense’s (DoD) approved Authorized Protective Eyewear List (APEL). Your vision is extremely important! For more information on protecting your eyesight, visit the Vision Center of Excellence.
It’s a fact: Teens need more sleep than adults. While most adults require a minimum of 7–8 hours of shut-eye, teens need 9 or more hours. (Newborns sleep 16–18 hours, preschoolers 11–12 hours, and school-age kids 10+ hours.)
However, most teens tend to sleep only 7.4 hours on school nights. Middle- and high-school students also have different sleep cycles from adults, making it difficult for them to fall asleep before 11 p.m. most nights. Homework, exams, sports, and other extracurriculars—even changes such as daylight savings time—can also throw your teen’s snooze schedule off-kilter. Does your teen crave screen time late at night? Blue light from computers, tablets, and cell phones can throw off their sleep cycles too. Plus, tuning into a recent text or social media post can get the brain going, which can also make it hard to fall asleep.
Teens’ body clocks can cause them to go to bed late and sleep late in the morning. Added to this, early school start times make it difficult for teens to get enough sleep. If possible, ask your local school officials about later start times, or consider finding schools with later start times. Students who attend schools that start later have:
- More weeknight sleep
- Less daytime sleepiness
- Fewer concentration problems
- Better attendance
- Improved academic performance
- Fewer car accidents
For more information, you can visit the National Sleep Foundation and the National Institutes of Health. Learn more about helping your teen get a good night's sleep—and wake up ready to start the day!
March is National Nutrition Month, a good reminder to eat healthfully and choose the best foods to fuel our bodies. This year’s theme is “Savor the Flavor of Eating Right,” which isn’t something we can often say about dietary supplements that come in the forms of pills and powders. If you’re looking for a supplement to lose weight, build muscle, or enhance your performance, HPRC always recommends choosing nutrient-rich foods first. They taste better and are better for you. Use the Operation Supplement Safety (OPSS) “Real Food” poster to see what foods can help you meet your goals.
If you’re still considering dietary supplements, be sure to visit OPSS where you’ll find answers to frequently asked questions, infosheets, videos, and other educational materials to help you make an informed decision. And remember to always talk to your doctor before taking any supplement.
Winter isn’t over yet, so here’s a reminder: You can get dehydrated in cold weather. And it isn’t always easy to hydrate, especially when you’re on a mission. If you’re active outside for less than 2 hours, it isn’t likely to be a problem. But if you’re out in the cold for hours or even days for a field deployment, the combination of heavy clothing and high-intensity exercise can lead to sweating, which contributes to dehydration.
You might not even feel as thirsty in cold weather as in the heat, because your cold-weather body chemistry could affect your brain’s ability to tell you when you need liquid. Cold weather also tends to move body fluids from your extremities to your core, increasing your urine output and adding to dehydration.
So when you’re in a cold climate, don’t rely on thirst to tell you when you need to drink. Drink often and before you’re thirsty. One way to determine your hydration status is to check the color and volume of your urine. (Snow makes a good test spot.) Dark, scanty urine indicates dehydration. Ideally, urine should be light yellow.
Water and sports drinks are the best fluids to maintain hydration, even in cold weather conditions. Carbonated and caffeinated beverages (including energy drinks) have a dehydrating effect because they increase urine flow. Also avoid consuming alcohol in cold weather. It might make you feel warm initially, but it can reduce your body’s ability to retain heat.
Enjoy exercising in the cold weather, but be sure to keep your water bottle in tow.
Stress can take its toll on your mental and physical health, including your heart health, but there are breathing techniques to buffer yourself from it! When you’re less focused on your breathing, it’s typical to breathe erratically—especially when you face the stressors of day-to-day life. In turn, your heart rate can become less rhythmic, causing your heart to not function as well.
But when you have longer, slower exhales—breathing at about 4-second-inhale and 6-second-exhale paces—your heart rate rhythmically fluctuates up and down. This rhythmic variability in heart rate mirrors your inhales and exhales so that you have maximum heart rate at the end of the inhale and minimum heart rate at the end of the exhale. More importantly, this physiological shift could help you feel less stressed, anxious, or depressed—and experience better heart health.
It’s easy to go through the motions of breathing while absorbed in your own thoughts; instead, take notice of your breathing and other body sensations. Regularly tuning in to your body sensations could help you feel more resilient and ready to:
- Adapt to change
- Deal with whatever comes your way
- See the brighter, or funnier, side of problems
- Overcome stress
- Tolerate unpleasant feelings
- Bounce back after illnesses, failures, or other hardships
- Achieve goals despite obstacles
- Stay focused under pressure
- Feel stronger
