Conventional foods and dietary supplements follow different rules when it comes to labeling, but the difference between the two isn’t always black and white. Such is the case with protein powders. If you look closely at various protein powders, you may notice that some are labeled with Nutrition Facts (required for foods), while others have Supplement Facts (required for supplements). So are protein powders conventional foods or dietary supplements? Read more in our OPSS FAQ on protein powder labels.

Exercising outside on hot summer days when the heat and humidity seem unbearable may be more harmful than helpful. Pollutants in the air (such as carbon monoxide, particulate matter, and ozone) can inflame your respiratory system more than usual, because on hot days you’re more likely to breathe faster and deeper and through your mouth (bypassing your nose’s natural filtration system).
However, the risks associated with not exercising at all are far greater than the risks of exercising outdoors. It may just take a little more planning on days and in conditions when pollution is bad. When planning outdoor exercise activities, follow these tips to limit your exposure to pollutants.
- Avoid exercising in areas of heavy traffic, such as along highways and during rush hour.
- During summer, exercise earlier in the morning, when ozone levels and temperatures are not as high.
- Check the domestic or international air-quality ratings to determine if it’s safe to exercise outside. Limit your time outside on Code Red and Code Orange days. Environmental conditions on these days are not healthy, especially for children, the elderly, and people with existing respiratory conditions.
- Exercise indoors when the air quality indicates high ozone and particulate levels.
- Before any demanding physical activity, limit your carbon monoxide exposure by avoiding smoky areas and long car rides in congested traffic.
Fall sports preparations are under way for many teen athletes, making it important for them to know what and when to eat and drink to be on top of their game. Two-a-days, strength-training programs, speed training—it sounds like the workout schedule of a professional athlete, but these are often components of teen athletes’ training for sports. Fueling the Adolescent Athlete contains valuable information on how they can fuel their bodies before, during, and after practice.
Fueling comes in two forms: what teen athletes eat to fuel up and what they drink to help stay hydrated. Eating nutrient-packed meals and snacks before, after, and even during practices and games is essential for optimal performance. The right balance of carbohydrates and protein work together to fuel and build muscles.
Staying hydrated goes hand in hand with peak performance. It can be difficult for adolescent athletes to stay hydrated in heat and humidity, but drinking regularly and keeping an eye on their urine color can be helpful.

If you suffer from concussions or traumatic brain injuries (TBIs), don’t be tempted to turn to dietary supplements to help you get back on the field. Several dietary supplement manufacturers have promoted products to help with recovery from concussions and TBIs, but there isn’t enough scientific evidence to support these claims. The Food and Drug Administration (FDA) is monitoring this issue and contacting specific companies making claims that their products can prevent, treat, or cure concussions.
FDA warns consumers to avoid using products that claim to prevent or treat a concussion or TBI. For more information about these claims and FDA’s response, see this Consumer Update.
Helping your kids limit their screen time can be difficult, but it could be the key to keeping your kids healthy. The American Academy of Pediatrics recommends limiting the total amount of entertainment screen time to only 1–2 hours a day, with no screen time for kids under the age of two. Yet the average 8-year-old spends 8 hours a day in front of a screen, and teenagers can even exceed 11 hours a day. That’s a lot of sitting around! The more time kids sit in front of a screen, the less time they spend being active, and the more likely they are to become overweight.
Here are some tips to help reduce screen time and, in turn, promote fitness:
- Keep the TV and Internet-enabled devices out of bedrooms.
- Stay informed: Monitor what media your kids are using, such as websites or social media applications.
- Watch movies and shows with your children. As a bonus you can use the entertainment as a way of discussing important family values and finding out what they think about certain scenarios.
- Make a family home-use plan for your media. For example, set a mealtime and bedtime curfew for cell phones and other devices. Establish some reasonable but firm rules.
- Be a role model. Encourage and join your kids in different outdoor activities.
You can learn to use the same mental imagery skills that elite athletes use to achieve peak performance. Mental imagery is the practice of seeing (and feeling) in your mind’s eye how you want to perform a skill, as if you were actually doing it. It’s a popular sport psychology technique that service members can take advantage of. You can enhance your usual training to help maintain—or even surpass—your current skill level, even when you’re sidelined.
Some of the benefits of mental imagery include:
- Better decision-making
- Fewer errors
- Improved attention
- Increased confidence
- Reduced stress and anxiety
You can create imagery in your mind for just about any task, such as improving your running time or marksmanship. Good mental imagery uses all of the senses, but it often helps to listen to a scripted audio recording. Use HPRC’s Building an Imagery Script worksheet to guide you through the steps of creating your own imagery script.
Watching others can also help. In fact, being a spectator can boost learning even more than mental imagery by itself because you’re viewing what you’d like to accomplish rather than conjuring up images with your own mind. Both methods of learning are effective. Observing can be in person or by video, but you can also combine video/imagery approaches and potentially get even more bang for your buck.
With any of these approaches, it’s important to “feel” yourself executing the skill, even though you might be sitting or lying down. Of course, you don’t have to be sitting still to use mental imagery. Try using it in the setting where you’ll actually perform the skill. You can even incorporate it into existing training protocols.
Carbohydrates are essential fuel for muscles and provide a source of quick energy. But is it true that eating extra carbs before an athletic event or mission will improve your performance? Carbs becomes especially important when you put your body to test during athletic competitions and events. If your body’s available carbs run out, fatigue sets in and you can “hit the wall.” To avoid this, many athletes load up on extra carbs such as bread, pasta, and rice. Read more about the concept behind carb loading and how it can affect your performance.
Take plenty of 30-second microbreaks to ease computer-related physical discomfort. Do you spend hours in front of your computer? Then you’ve probably noticed that your neck, low back, shoulders, and wrists can feel tired and sore afterwards. A great strategy that can help these discomforts is to take “microbreaks”—30-second breaks from your computer. They can help even if you’re just working for 3 hours at a computer—much less a full workday! Some tips to consider:
- Take a microbreak every 20 minutes when working in front of a computer.
- Don’t wait until you feel the need for a break. It’s more helpful to create a specific break schedule than to wait until it feels like time to take one.
- Don’t worry about taking micro breaks and getting less done. For most tasks, microbreaks actually don’t negatively impact productivity.
Recovery Care Coordinators (RCC) help wounded, ill, and injured service members, their caregivers, and their families navigate the recovery, rehabilitation, and reintegration process. They help ensure a smooth transition from a recovery and rehabilitation setting back into the civilian community or, in some instances, back to military duty. An RCC is the first point of contact within each of the military services’ wounded warrior programs. RCCs are located at military treatment facilities and installations throughout the country and overseas. Referral to RCCs can come from the service member, a caregiver, a family member, medical personnel, or a wounded warrior program. For more information on the referral process (and for contact numbers), read this factsheet.
How do RCCs help support service members, their caregivers, and their families during what is often a difficult and stressful period in their lives? The RCC develops a comprehensive recovery plan (CRP) with the service member, caregivers, family members, and the recovery team to identify goals and resources needed to achieve those goals, such as assistive technology, education, employment, or housing.
The DoD Office of Warrior Care Policy is responsible for oversight, policy of the Recovery Coordination Program, and standardized training for all RCCs, but each military service branch implements its own Recovery Coordination Program in accordance with DoD policy. The terminology may differ with service (for example, advocate, care coalition, recovery care), but the mission and the standards are the same. Check out the following links for service-specific information:
The benefits of exercise in the postpartum period (six to eight weeks after delivery) include decreased physical, mental, and general fatigue, in addition to improved fitness and motivation. It may even reduce depression, as long as the exercise relieves stress rather than provokes it.
Some women who exercise during their pregnancy and immediately resume exercise after giving (vaginal) birth aren’t at risk for post-partum complications (such as excessive or prolonged bleeding, uterine inversion, or infection). However, most women don’t meet the recommendations for exercise during pregnancy, so when you do resume exercise, you should do so gradually.
You may be concerned that exercise could decrease your milk supply; however, exercising women who drink enough fluid (stay hydrated) and eat enough to meet their caloric needs continue to produce enough breast milk. Composition of breast milk remains the same with moderate exercise intensity, but vigorous exercise can cause lactic acid to appear in the milk, which could affect how well your baby accepts your milk. Consider nursing before participating in vigorous exercise.
Returning to physical activity after giving birth depends on the individual. Be sure to discuss your exercise habits and plans with your doctor before resuming your regular workout routine. Visit this web page from The American Congress of Obstetricians and Gynecologists to learn more about exercise in the postpartum period. Stay healthy for you and your baby!
