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.
Even the most successful people wonder, at times, if they’re good workers, leaders, or parents. However, some can be overwhelmed by self-doubt. And they worry they’ll be exposed as fakes or frauds to others—otherwise known as “imposter syndrome.” Try these strategies to fight your fears and perform well.
- Normalize it. Take some comfort in knowing that others experience self-doubt—and get through it. You’re not alone.
- Try on different thoughts. When you treat your thoughts as facts, they can take on a life of their own. Don’t assume the worst and think, “I’m going to fail.” Instead control your thinking and tell yourself, “This is going to be hard, but I can do this.”
- Look to others for inspiration. You can feel even more inspired when you find similarities between other successful people and yourself. For instance, maybe he or she is hard-working, imaginative, or organized—just like you.
- Chill out and breathe. If you’re too amped up, it’s hard to focus on the task at hand. Allow yourself some longer, slower exhales, and enjoy clearer thinking.
- Remember your successes. Mental imagery is a powerful tool. Thinking about past times when you were successful—regardless of when they occurred—might help you feel more confident.
- Know you don’t “need” confidence. Certainly you’d like to feel self-assured before you perform, but you don’t have to feel confident at first. People often perform well and then experience confidence.
- Fake it ‘til you make it. "Acting" successful can help you actually become successful. And if you have some screw-ups along the way, own those mistakes and learn from them.
There’s no magic trick to overcoming imposter syndrome, but you can use these approaches to help defeat doubt, believe in yourself, and celebrate success!
Picamilon goes by many names, such as pikatropin and nicotinyl-gamma-aminobutric acid, but one thing it can’t be called is a dietary ingredient. In 2015, the Food and Drug Administration declared that picamilon is not a legal ingredient in dietary supplements and sent warning letters to 5 companies whose dietary supplement products contained picamilon. So why is it illegal? Find out in the Operation Supplement Safety (OPSS) FAQ about picamilon.

What role does a smoothie play in your meal plan: meal, snack, or post-workout fuel? If it’s a meal-replacement, then choose one that includes dairy, some fruit, and maybe vegetables. Is it a snack? Then go lighter and pick one with fruits, vegetables, and ice. And if you’re replenishing fuel after your workout, then make sure your smoothie includes protein—and choose the protein source wisely.
Make them quickly: Just dump your ingredients into a blender, hit start, and blend to desired consistency. That’s it! They can include any combination of fruits—such as berries, cherries, apples, melons, bananas, and grapes—and vegetables (such as kale, spinach, and cucumbers). Try freezing some ingredients for an icier drink. You also can use frozen bags of smoothie ingredients, saving time and decision-making. But avoid adding juice because it contains little (or no) fiber and extra calories.
There are many protein options too. Milk (dairy or nondairy) and plain (or Greek) yogurt also provide calcium. Nut butters can be flavorful as well. But remember 2 tablespoons add an extra 200 calories.
Choosing ready-to-drink dairy or juice smoothies? Some contain added sugar, and others with mostly apple juice aren’t as nutrient-dense as ones made with other fruits and vegetables. And check the Nutrition Facts panel because some bottles contain two (or more) servings. This is especially important because you’ll want to get the proper nutrients without going over your daily calorie needs.
Tip: Try a refreshing blend that includes 1 cup watermelon, ½ cup strawberries, 4 ice cubes, and ½ tsp lemon juice. Make sure to experiment with multiple combinations and flavors, and include more fruits and vegetables! And read HPRC’s FAQ about juicing to learn more.
Can you train in the heat to improve your performance at altitude? The answer is “sort of.” “Cross acclimation” or “cross tolerance” is the idea that exposing yourself to one environmental condition can help you adapt to another one as long as they have certain things in common.
As it turns out, this is the case for heat and hypoxia (low oxygen). This is important because athletes and service members can be exposed to altitude without prior or sufficient acclimatization. Altitude sickness can cause several problems, especially decreased performance. But some evidence shows that this method of training in hot conditions to prepare for altitude can actually work.
If you climb to the top of a mountain, there’s less air and less pressure. And you’re getting less oxygen with each breath. This can be simulated at sea level (in special labs) where pressures are normal, but the amount of oxygen in the air is reduced (fake altitude).
However, there’s a bit of a catch. Training in the heat under artificial low-oxygen conditions—normobaric hypoxia or “fake altitude”—involves normal pressure, which is different from “real altitude” or hypobaric hypoxia, which involves reduced oxygen at low pressure. The difference is in the pressure.
So, do these two environments cause the same types of physiological changes? There are several other factors involved in real-altitude acclimatization that might not be accounted for at fake altitude, so the jury’s still out.
Training in the heat might prepare you for performance at altitude—to a point. Ideally, if you’re going to be at altitude, try to acclimatize yourself as much as you can.
Deciding to end your marriage isn’t easy. Yet divorce is a reality for many couples. There are many issues to consider because it can have a lasting effect on your family, home, health, and job—but especially your well-being.
- Which couples divorce? There’s no “typical couple” destined to divorce. However, those who frequently argue and rarely spend positive time together are more likely to divorce. The same couples also risk violence and instability in their relationships. Frequent disagreements over money also are linked to higher divorce rates. Still, couples with fewer challenges divorce too.
- Can therapy help? Counseling offers a neutral place to talk through your thoughts and feelings. Therapists offer an unbiased view with the intent of finding what’s best for the couple. Counselors also encourage them to consider the impact of their actions and help them explore different ways to think and behave. But counseling is only useful when you’re motivated and committed to work towards change. Don’t wait until things become too desperate before seeking help from a therapist or religious leader.
- What else is there to consider? If you have children, you’re likely to be concerned about what might change for them and how you’ll help them cope. Give some thought to how you’ll maintain your financial security too. And start now to strengthen your social support—your relationships with friends and family—to help you through the process.
- Why stay? You might choose to remain in the relationship if your spouse is making efforts to change. Still, it’s important to work together to create your optimal relationship. Some aren’t sure if their marriage will last. But they also want to see signs that reaffirm their love, which sometimes helps them decide to stay.
This Father’s Day, HPRC salutes the many fathers who serve their country, families, and children. Dads play an essential role in families because they teach their kids about being healthy, smart, and kind. And it makes a difference.
So how do fathers teach their kids to become good people? Some dads help their children tune in to their own emotions as well as what others are thinking and feeling. Empathic kids are able to tolerate some degree of anger and guilt. And they use these emotions to look out for themselves and others.
School-age children with involved fathers are more likely to earn better grades and enjoy school. Dads can get more involved by helping their kids with homework and attending school events. Ask your kids about what they’re learning and help foster that curiosity.
Try to volunteer when your schedule allows it too. Coach your child’s sports team or serve as a scout leader. Pick whatever activity he or she enjoys—and your athlete or “mathlete” will shine.
Dads also can help put the fun in family fitness. Organize a bike ride, challenging hike, or fun day at the pool. Fathers with healthy-exercise habits help motivate their kids to be physically fit and active.
Remember to teach your children how to fuel their bodies. Set a good example for your kids to follow. Choose healthy snacks and drinks often because your kids are likely to eat and drink “what Dad’s having.” And ask them to help create your favorite salsa, pancakes, and chili in the kitchen. Make sure to involve the entire family during cleanup too.
Fathers near and far: Thanks for all you do!
When you wake up at the end of a sleep cycle, you initially feel rested and fresh. If you wake up before a sleep cycle finishes, you’ll probably feel groggy. However, you still get the benefits of that sleep. Here’s how it works: There are 5 stages of brain activity in one sleep cycle. And each cycle lasts about 90–120 minutes. You fall asleep during the earlier stages.
Next, you experience deep, restful sleep. Your heart rate and breathing slow down during these stages, while your body remains still. Your brain is most active during the final sleep stage. As you dream, your eyes move under your eyelids in rapid eye movement (REM). If you wake up during these later stages, you’ll likely feel groggy. You’ll feel more rested waking up at the end of a sleep cycle (ideally in the morning, after several sleep cycles). Or you can feel refreshed waking up after a 20–30 minute nap (before you enter deep sleep).
Sleeping 8–9 hours every day is important—however it happens. And you can shake off any grogginess or “sleep inertia” if you take 15–30 minutes to fully awaken. Standing upright and spending time in light—ideally daylight—can help! As long as you have enough time to fully overcome sleep inertia, you might find that the benefits of a little extra sleep are worth it.
Don’t worry about getting enough deep sleep or REM sleep. Trust your body! It has an amazing ability to recuperate when you catch up on sleep. And it will quickly fall into whatever stage of sleep you need most.
Hemp is turning up in a variety of foods, beverages, and dietary supplements, and most service members need to keep an eye out for this ingredient on product labels. While hemp provides important nutrients such as protein, it also contains tetrahydrocannabinol (THC), the main active ingredient in marijuana. The levels of THC in hemp used for food and supplements are much lower than those in marijuana, so products containing hemp shouldn’t get you “high.” But don’t run to the store just yet! Although DoD does not have a specific policy regarding hemp, each service does. Check the OPSS FAQ about hemp for your service’s policy on hemp.
The Food and Drug Administration just unveiled an updated Nutrition Facts panel, which is easier to read and reflects the 2015–2020 U.S. Dietary Guidelines. Recently revised after 20 years, this new format must appear on all packaged foods by July 2018 (with some exceptions). These are the facts to know:
- Highlighted calories, servings per container, and serving sizes. This information is larger and bold, making it easier to find at a glance.
- Vitamin D and potassium. These are now listed, since many Americans don’t get enough of these important minerals. Vitamin D maintains bone health, and potassium can help reduce blood pressure. Vitamins A and C are no longer included since deficiencies of these are rare.
- Added sugars. “Total Sugars” includes what’s added and what’s naturally occurring (but with “Added Sugars” also noted separately). This new information is especially important for those who are managing their nutritional needs and limiting their calories to less than 10% from added sugars.
- Updated “Serving size.” These now match what people typically eat or drink. For example, a single serving of soda might be 12 or 20 oz., depending on the packaging.
- Clearer footnote. The footnote better explains what “% Daily Value” means.
- Multiple serving sizes. Some packages, such as a pint of ice cream, include two columns: “per serving” and “per package.” This makes it easier to choose whether to eat or drink one serving—or the entire package—at one time.
Watch for the new Nutrition Facts panel to appear on your favorite packages soon. In the meantime, you can view it below.
Close relationships provide social support that can help relieve stress. One type we don’t know much about is “bromances”—close friendships between two men—but how these help or hurt stress levels isn’t clear.
It’s hard to do scientific research on this topic with humans because it would involve intentionally stressing people out to see how they respond. Who would volunteer for that?! So instead, scientists who study human social behavior use rats, which have social behavior very similar to that of humans. To learn more about the impact of bromances on stress, they observed male rat “friendships” under stressful situations. Here’s what they found.
Under mildly stressful situations, male rats became more social and cooperative with other male rats, compared to when they weren’t stressed. The rats’ oxytocin levels increased. They touched and snuggled other male rats more. Under severely stressful situations though, the male rats’ behavior changed. They were no longer cooperative and became withdrawn, isolated, and aggressive.
Of course, people aren’t rats, and one research study is never a good foundation for reliable conclusions, often raising more questions than it answers. However, it can give us “food for thought.” One idea from this study is that bromances seem beneficial, depending on stress level. Your friendships with other guys might help keep mild stress at bay. So spending time with your fellow men just might help you feel calmer.
Yet in severely stressful situations, bromances didn’t serve the same purpose. The rats became disconnected and hostile. Could the same be true for male humans? We can’t say for sure, but men exposed to severely stressful situations that result in PTSD sometimes have similar reactions.
