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.
Make at least half of your grain choices whole grains. Unlike refined grains, whole grains contain all parts of the grain and are good sources of fiber and other nutrients that are essential for good health. Try these tips so you can enjoy more whole grains in every meal and snack:
- Breakfast: Start with a hearty breakfast that features whole-grain cereals such as steel-cut oats or shredded wheat. Have to eat breakfast on the run? Try switching to whole-wheat toast or whole-grain bagels instead of plain bagels.
- Lunch: Sandwiches using whole-grain breads or rolls are full of flavor and fiber. Swap out white-flour tortillas with whole-grain corn tortillas.
- Dinner: Sides can really shine when you replace white rice with exotic black, brown, or red rice, quinoa, or bulgur. Add wild rice or whole-grain barley to soups, stews, and casseroles. In the mood for noodles? Try whole-wheat pastas for added texture.
- Snacks: Snacks can feature whole grains too. Air-popped popcorn, whole-grain crackers, and granola bars are tasty and healthy options to keep you going throughout the day.
Can’t tell if some of your grain products are whole? Look at the ingredients list and make sure the first ingredient says “whole wheat” or “whole grain.” HPRC also has a grains table that points out nutritious grains (with and without gluten). And keep in mind that words such as “100% wheat” and “multigrain” don’t necessarily mean whole grain. For more information, visit the Whole Grains Council.
Exposure to a natural green environment can help reduce your stress levels and improve your health and well-being. So, feeling blue? Go green! Some of nature’s restorative benefits include improved positive mood, energy, and vitality; decreased anxiety, depressive thoughts, perceived stress, and hostility; as well as improved recovery times after surgery and less need for pain meds.
Exposure to nature can also reduce your heart rate, blood pressure, blood sugar, and stress hormones, as well as improve your sleep, immune function, and brain activity. Interestingly, people who live in neighborhoods where streets have more trees report feeling healthier, with fewer symptoms of poor health such as heart attack, stroke, obesity, and diabetes. Neighborhood greenness has also been tied to longer life expectancy.
Depending on where you live, finding a natural environment can be tricky. You can find state and national parks online or look for local parks and gardens in your area. Even walking along a neighborhood street with lots of trees, spending more time viewing nature (through a window), or having indoor plants within view can make you feel better. You may want to experience nature on your own, with a buddy, or with a group of fellow service members or veterans. For group outdoor recreational activities, check out the Sierra Club Outdoors program (or, specifically, their Military Outdoors program). So if you’re feeling stressed, down, or not your usual self, get outside and go green!
The condition known as “dental caries” is the most common and chronic childhood illness, but you can help your child avoid it. Bacteria that build up on your children’s teeth and produce acid can destroy enamel and dentin, leading to decay, infection, and cavities. Thankfully, there are a few simple ways to prevent this.
- If your young child uses bottles, make sure you put your child to sleep without a bottle.
- Avoid continual use of a bottle or sippy cup, especially with fluids other than water.
- Limit sugary foods and drinks, and the latter should include only 100% juice.
- Allow less than 4–6 oz. of 100% fruit juice per day.
- Start brushing your child’s teeth twice a day as soon as their teeth are visible.
- Use no more than a pea size dot of fluoride toothpaste for children 3 and up and a dab the size of a grain of rice for younger children.
- Take your child to a dentist before the age of one.
- Parents and caregivers can spread bacteria to babies and children accidentally, so take care of your own teeth! And it’s a good idea not to put food or other items into your child’s mouth after they’ve been in your mouth, especially if you have a history of cavities.
If you use these simple tips, you can strengthen your child’s teeth throughout childhood. For more information, check out the American Academy of Pediatrics article “Brushing up on oral health: never too early to start.”
Many factors affect your sleep, including stress and exercise, but your diet can also have a huge impact on the quality of your sleep, particularly in the hours before you go to bed. By improving your evening food habits you can sleep better, which can have a positive impact on your mental and physical performance, immune function, relationships, and overall health and well-being. Try these tips to be on your way to a better night’s sleep:
- Limit caffeine. Caffeine can disturb your sleep even many hours later. If you typically drink coffee or tea in the afternoon or after dinner, opt for a decaffeinated version. And be wary of hidden sources of caffeine.
- Avoid alcohol. Some people think of alcoholic beverages as a nightcap to help you sleep better. While it may help you go to sleep faster, it also reduces sleep quality by waking you up in the middle of the night.
- Eat balanced meals. Eating balanced meals daily will help you get all the nutrients you need, such as B vitamins and magnesium, to promote better sleep. A balanced plate is ½ a plate of fruits and vegetables, ¼ plate of whole grains or starchy vegetables (corn, peas, potatoes), and ¼ protein, plus a serving of healthy fat (oil, avocado). In addition, your body takes long to digest fats, so eating too much fat may keep you from falling asleep.

Don’t make things harder for yourself by making excuses or creating excuses in advance. When you set a goal and the stakes feel high, it can be easy to make excuses when you fail in order to avoid negative feelings such as regret, shame, or guilt. Without thinking about why you do it, you may sometimes make tasks harder than they need to be so that ready-made excuses “protect” you from feeling bad. The downside is that you miss opportunities to learn from your experiences and test your “true” skills. This is called “self-handicapping.” Learn how to set yourself up for success instead.

Music can have a huge effect on your performance and mood during exercise. Without realizing it, most people push themselves harder or move faster during exercise when listening to fast-tempo music, which increases heart rate as well as speed, endurance, and in some cases the rate of perceived exertion. Exercisers also feel an improved sense of well-being when working out to music.
So why is it you prefer certain songs when you’re exercising? One explanation suggests that a part of your brain tries to match the movement of your body to the beat of the music. In fact, scientists have found that when you listen to music with about 125–140 beats per minute, both your heartbeat and your movements synchronize to work at the most energy-efficient, optimal level for exercise. In essence, the music works with your brain to coordinate your bodily functions and optimize your workout.
The best workout songs seem to share certain characteristics:
- 125–140 beats per minute during exercise, but slower for warm-ups, cool-downs, and some endurance-type exercises
- A motivational or upbeat message
- Familiar tunes or a preferred style of music
- A tempo that matches the rhythm of your exercise
Ask your buddies about their workout playlists too. They might have something totally different to offer—a new beat to stay fit with. So turn on, tune in, and train!

The ultimate performance mind state is often referred to as “the Zone,” which scientists refer to as “flow.” It isn’t something you can decide to suddenly experience, but you can remove obstacles and learn mental skills that help pave the way. This experience of being completely immersed in an activity involves:
- Clear goals and immediate understanding of whether actions are helping or hurting your progress towards goals.
- Being intense and focused on the present moment.
- A merging together—in the moment—of what you do and what you are aware of.
- Not feeling self-consciousness or anxious.
- Time slowing down or speeding up.
- Your attention focused on exactly where you need it to be.
- Feeling challenged yet taking opportunities even when they’re a slight stretch.
- Feeling in control and prepared to face whatever happens next.
You can experience the Zone in many ways, whether you’re engaged in combat, playing competitive sports, or raising children. It can’t be forced, but you can set the stage for it by doing many hours of deliberate practice and by honing good mental skills.
The post-workout recovery phase is just as important as the workout itself. Refueling with the right nutrients can help your body heal damaged muscles, build more muscle, and replace nutrients lost during exercise to prepare you for your next workout or mission. A combination of protein and carbs in a snack is the key for recovery. It’s also important to drink enough fluids for rehydration. The best time to refuel is within 45 minutes after your workout, but if you plan to have a meal within 2 hours, you can skip the snack. Otherwise, you might be eating too many calories, which would spoil all your hard work. For more guidelines and snack ideas, please visit HPRC’s Peak Performance: Refueling.
Exercise leading up to and during pregnancy has many health benefits. Recently, the effects of exercising during pregnancy have been found to benefit the birth process as well. Regular exercise with pregnancy can contribute to a healthy birth weight for your baby without increasing the risk of premature birth. It may even decrease the risk of needing an unscheduled cesarean birth. For these reasons, continuing your exercise routine could help you have a healthier and safer birth. Staying active contributes to a healthier pregnancy. It also helps you maintain a healthy weight and establishes exercise habits that, if continued after your baby is born, help you get rid of the weight gained during pregnancy. There are many ways to keep up with your physical fitness during pregnancy while still keeping you and your baby safe.
