Refuel, rehydrate, recover

HPRC Fitness Arena: Nutrition, Total Force Fitness
Proper refueling after exercise is just as important as the exercise itself. Optimize your recovery with nutrition so you can stay fit and healthy.

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.

Moms-to-be: exercise for a healthier birth

There are many benefits of continuing to exercise while pregnant. Now you can add healthier birth weights and a reduced chance of C-section to the list!

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.

Stress can zap your relationships

Stress can make you impatient, disagreeable, and less able to solve problems. Learn some tips for how to reduce its effects on your relationships.

When stress threatens to overload you, be careful it doesn’t spill over into your relationships. Stress can make you less patient with your loved ones, less able to solve problems well, and more disagreeable.

When you’re under a lot of stress, you’re also more likely to feel negative about your relationships. This generally leads to more fighting, which can be especially tough for military families if one of you deploys or leaves for training before you’re able to rebalance your relationship and de-stress. While you’re apart, negative feelings can fester and further damage your relationship.

But just knowing about how stress can impact your relationships is the first step. Next time you feel stressed out, don’t let it fester. Instead, do something about it. To ease your stress, you can try:

  • Deep breathing or another mind-body skill that can switch you from your body’s stress response to its relaxation response.
  • Exercise, which can make you feel better and lower your stress.
  • Something just for fun, which can take your mind off your stress.
  • Connecting with a loved one. Feeling loved and supported can also reduce stress.

Finally, if you’re apart from your loved one, set aside time regularly to connect to him or her, regardless of the last fight you had. Try to give each other benefit of the doubt and move past the argument. You can always finish discussing it when he or she returns. 

Noise pollution and hearing loss

HPRC Fitness Arena: Environment, Total Force Fitness
Helicopter propellers, jet engines, explosions, moving vehicles, gunfire, and more—all sources of noise pollution that troops may experience in the line of duty—can affect your hearing.

Noise-related hearing loss is a tactical risk for individual warriors and unit effectiveness. Being able to hear well is crucial for effective communication and—perhaps more important—for survival. While the military has done extensive research and established standards regarding noise and noise exposure, there are a few things you can do to help minimize your risk of this occupational hazard.

  • Wear hearing protectors when firing weapons or traveling in noisy vehicles or aircraft.
  • Make sure that earplugs such combat arms earplugs (CAE) fit properly to protect your hearing but still communicate effectively.
  • Replace lost or damaged hearing protectors as soon as possible.
  • Limit exposure to “annoying noise” during normal daily activities. Trying to ignore noise can increase your heart rate and blood pressure and cause sleep problems and other negative health effects.
  • Report any signs of hearing loss as soon as possible.

Hearing loss, including tinnitus, has become an "invisible" injury and an accepted outcome of military service. Blast injuries from improvised explosive devices (IEDs), RPGs, and mortar rounds are the largest cause of hearing loss for forces in Iraq. Compensation payments for hearing loss as the primary disability increased 319% between 2001 and 2006. While there is currently no cure for tinnitus, there are treatments available.

The DoD Hearing Center of Excellence is committed to preventing, treating, and rehabilitating hearing loss and auditory injury for service members and veterans. HCE offers evidence-based clinical care in collaboration with other organizations and Centers of Excellence to improve quality of life for hearing-impaired service members and raise awareness about noise pollution and occupational safety.

Noise pollution may be an inevitable part of serving in the military, but it doesn’t have to leave you with a permanent reminder. Do what you can to help hold on to your hearing.

Snacking for success

HPRC Fitness Arena: Nutrition, Total Force Fitness
Does the word “snack” bring visions of junk food, candy, and chips? Think again! Nutritious snacks are a great way to boost your mind and body.

You missed a meal and plan to exercise soon or your next meal is hours away, but your stomach is rumbling – what can you do? One way to fill your nutritional gaps is with nutrient-packed snacks.

Nutrient-packed snacks should consist of both “plants” and protein. Plants—such as fruit, vegetables, and whole grains—contribute carbohydrates, vitamins, and minerals. Protein—including low-fat dairy, lean meats, nuts, and seeds—contribute to muscle building and repair. Here are some simple snack ideas to have on hand during your workday, at the gym, and during missions to keep you at the top of your game, both mentally and physically:

  • Apple or pear with 2 tbsp of natural peanut butter or almond butter
  • Homemade trail mix –2 tbsp of dried fruit (any kind) mixed with a handful of nuts or seeds (any kind)
  • Whole-grain crackers with 1 oz of cheese
  • Whole-grain English muffin with 2 slices of turkey
  • Slice peaches or plums, add to 1 cup of cottage cheese or plain Greek yogurt, sprinkled with cinnamon
  • Cut-up veggies like carrots, cucumbers, bell peppers, and sugar snap peas; dip in hummus or bean dip

Low glucose (blood sugar) from lack of food can affect memory, learning, and attention. In addition, inadequate fuel can slow down your physical performance and your ability to recover from injuries, strenuous exercise, or difficult missions. Snacking can be a great way to fuel your body between meals and provide extra nutrition if you’re highly active.

But don’t forget to look at your portion sizes! Remember, this is a snack, not a meal. Snacking when you’re not truly hungry or large portion sizes can result in weight gain. Learn more about stocking your snack drawer.

Don’t get “computer eyes”

Take regular breaks and adjust your computer environment to prevent eye strain and enhance performance.

Sitting in front of a computer for hours can make your eyes tired, and your visual performance can suffer. To help with potential negative effects, create an environment that has equal brightness everywhere around your computer screen. Try these tips to help:

  • Reduce intense fluorescent lights.
  • Turn on some lights if you usually look at computer screens in the dark.
  • Dim excess light coming through windows with blinds, tinting, or window covers.
  • Avoid glare on your computer screen.
  • Take microbreaks to look at distant objects.

If you’re in an office environment, if possible, turn off overhead lights and have a table lamp for softer light. If you can’t control the lighting in your environment, there are screens you can place on top of your computer screen to reduce glare. In a previous article, we highlighted how 30-second microbreaks every 20 minutes can ease physical discomfort and improve mental performance when working in front of a computer. Similar breaks also help reduce eye strain. Experts suggest looking at a distant object at least twice every hour to help prevent visual fatigue. So if you take a break every 20 minutes for brief stretching, make sure it also includes looking at a distant object to help both your eyes and body. 

Supplements and medications – What’s the problem?

Dietary supplements can affect how medications work in your body. Read more on what you can do to keep yourself safe.

Dietary supplements and medications (prescription or over-the-counter) can be a dangerous combination. Many dietary supplement ingredients, especially herbs and botanicals, can interact with drugs or even other dietary supplements, which can either increase or decrease the effectiveness of your medications. In other words, you could be getting too much or too little of the medications that you need, putting your health at risk.

If you are taking or plan on taking a dietary supplement, inform your healthcare provider to make sure it’s safe to use with your medications. Even then, you should still take caution, as some dietary supplements contain ingredients not listed on the label.

The Food and Drug Administration (FDA) advises consumers to be aware of certain supplement/drug interactions and offers tips to stay safe. For more information, see the FDA’s Consumer Update. And for information about many known interactions, visit the Natural Medicines Comprehensive Database (NMCD).

What exactly is a “trigger point”?

What is a trigger point, and how can one be treated?

Does it ever feel like there’s a baseball in your calf? Or what about that tight spot under your should blade? This might be something called a trigger point, more commonly known as a “knot.” Even experts aren’t completely sure what they’re made of, but they seem to be caused by overuse and/or bad biomechanics (that is, bad posture).

Getting rid of these annoying knots usually involves massaging the heck out of them. If you can reach the knot, you can massage it yourself to try to loosen it up. Or you can use things like foam rollers or massage balls to help. If that still doesn’t work, you can talk to your doctor about other treatments such as ultrasound, physical therapy, dry needling, acupuncture, or injecting the knot with medicine.

Even with these treatments available, it’s important to first avoid actions that create trigger points, such as poor posture or exercising without warming up. Don’t confuse trigger points with the sore muscles which can occur after a workout (delayed onset muscle soreness). This kind of soreness is usually harder to pinpoint but will go away on its own after a couple days or less.

Also, make sure you’re exercising with proper form. Ask a certified personal trainer, if you’re not sure. Keep in mind that if your pain began with an accident or lasts after trying treatments at home, you should consult your physician or other healthcare provider. 

Dealing with frequent separations

Separations are a way of life for many military families. Learn some tips for how to navigate them better.

Deployment and other military-related separations can be tough on families, but many families can (and do) learn how to adapt to them. The regular rounds of separations that come with military life require constant adaptation. Naturally, when a partner is away from the family for a certain period of time (such as during deployment or training), those at home have to shift their roles and responsibilities to cover for the person who’s away, especially with regard to childcare. When the service member returns home, then the family must shift roles again. These “accordion families” continuously contract and expand as members of the family are physically present or absent. Some families handle this smoothly, but others find it to be one additional hurdle to overcome again and again.

There are two important things you can do to help manage these repeat transitions:

  • Work on everyone in the family communicating well.
  • Try to stay as emotionally connected as you can while apart.

Of course, these tips are easier said than done. Think about how you usually handle separations: Do you emotionally distance yourself from your partner? Do you become more “needy”? How does your partner respond? Do you both do the same things, or do you have opposing emotional needs when apart? If you have children, how do your children respond?

If you have different emotional needs, this can create instant conflict and feelings of distance. One way around this is to talk about what you each need, figure out where there’s common ground, and make a game plan that can fulfill each person’s needs as much as possible while at home and when apart.

You can use the strategy on HPRC's card on communication skills to help better navigate these kinds of conversations. Plus, remember to not fall prey to these common thinking traps that create misunderstandings in relationships.
