Prescription stimulants can improve attention and alertness, and doctors prescribe them for people with Attention Deficit Hyperactivity Disorder (ADHD) or excessive fatigue. Used improperly and without the supervision of a health provider, these drugs have serious side effects. Some people misuse and/or become addicted to them. Learn more in HPRC’s “Stimulant drugs: use and misuse.”
Last summer the Netherlands removed the weight-loss dietary supplement product Dexaprine from the market due to reports of serious adverse events, but the results of research into the cause has just been released. A recent article in Drug Testing and Analysis described at least 26 cases of Dexaprine toxicity reported to the Dutch Poisons Information Center. Testing revealed the existence of “a cocktail of synthetic stimulants” including synephrine, oxilofrine, deternol, yohimbine, caffeine, and theophylline, and possibly ß-methyl-ß-phenylethylamines. (Problematic forms of phenylethylamines, including ß-methylphenylethylamine. were discussed in an April 2014 article in the New England Journal of Medicine.) For more information about tainted weight-loss dietary supplements, see the Food and Drug Administration’s information. Note that this product is still available in the U.S. and online.
Have you been experiencing symptoms such as sneezing; a runny nose; watery and/or itchy eyes, and fatigue? Colds and allergies both can make you feel miserable and affect your performance, but it can be hard sometimes to tell which is which. The causes of each are distinctly different: Colds are contagious, and they are caused by viruses. But allergies are due to sensitivity to allergens such as seasonal pollen, and they’re not contagious. To prevent colds, hand washing is key, along with hygiene etiquette such as covering your mouth or nose when you cough or sneeze. To avert allergies, on the other hand, try to avoid the allergens that cause your symptoms. Common allergens, especially in the spring, include grass and tree pollen. Year-round allergens include mold, animal dander, and dust mites. It can be a challenge to exercise and enjoy the outdoors if you have allergies, but it’s not impossible. Here are some tips to help you manage your allergies:
- Know and avoid your allergy triggers. If you’re not sure what you might be allergic to, getting tests done by a specialist could help you narrow it down. A doctor might also suggest an antihistamine or inhaler to help prevent flare-ups.
- Check the air quality in your area every day. If the pollen count is high, avoid spending too much time outside, mowing the grass, or exercising outdoors.
- Shower after being outside. This can help reduce symptoms by washing pollen off your, skin, hair, and eyelashes.
- If you must be outside during high pollen/pollutant times, wear a cover (such as a mask or bandana) over your mouth and nose to keep particles out of your airways.
- Rinse out your nose with a saline spray to help wash away allergens after being outside.
Need a great post-workout beverage? Try drinking a glass or two of chocolate milk during the first 15-60 minutes after exercise to replenish glycogen stores and repair muscles.
Why chocolate milk? The carbohydrate-to-protein ratio in chocolate milk is roughly four-to-one, the best ratio for replenishing glycogen stores while providing adequate protein for muscle building and repair. One eight-ounce glass of chocolate milk provides about 200 calories. It provides carbohydrate, protein, electrolytes such as potassium and sodium, and essential vitamins and minerals such as vitamin D and calcium in an easily digestible liquid form that is inexpensive and readily available, and it tastes good! But be sure to choose heart-healthy low-fat versions.
For those who are lactose intolerant or allergic to dairy products, or for those who simply prefer a plant-based diet, fortified chocolate soymilk is a great alternative.
If you find yourself at odds with those around you more than you’d like, think about bolstering your communication skills. Communication is a key skill in all relationships, and half of this skill is knowing how to listen. “Active listening” lets your loved one, friends, and associates know that you heard them and understand their perspective. Active listening happens when the listener—you—takes part in the conversation, not just listens. Here’s how you do it:
- Repeat back to the other person the gist of what he or she just said.
- Reflect the other person’s feelings; that is, recognize out loud that you understand how he or she feels
- If you need clarification, ask for it in a gentle way.
- Show interest and curiosity in what the other person is saying.
To see what this might look like, watch this video from the Kansas National Guard about active and constructive communication. FOCUS has a handout on “Effective Communication Skills” that further describes this skill.
Have you heard of Total Force Fitness, but you aren’t sure what it is? It’s a framework for building and maintaining health, readiness, and performance in the Department of Defense. It views health, wellness, and resilience as a holistic concept that recognizes “total fitness” as a “state in which the individual, family and organization can sustain optimal well-being and performance under all conditions”—a connection between mind, body, spirit, and family/social relationships. Total fitness shifts the perspective from treatment to wellness and focuses on prevention and strengths.
The Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury created a slide presentation for units and groups on Total Force Fitness: A Brief Overview that describes what TFF is, its core components, and each of its eight “domains” (behavioral, social, physical, environmental, medical and dental, spiritual, nutritional, and psychological). For more in-depth reading, check out the original Military Medicine Supplement that started it all, including a scholarly chapter for each domain.
Everyone experiences stress, but how you interpret stress determines how stressed you feel. This process is often referred to as the “ABCs of stress”:
Activating event + Beliefs = Consequences
When you experience an event, you interpret that “Activating event” according to your “Beliefs”—the lens through which you view the world. Generally, your interpretation is what causes your feelings of stress—that is, the “Consequences.” This is why two people can go through the same event and be affected in very different ways. If your interpretation of events leads to high levels of stress, you can manage your stress by finding ways to reframe your interpretation.
Afterdeployment.org suggests making a “Stress Toolkit” in which you identify helpful coping strategies. These could be strategies that ignite your relaxation response or reframe your thinking (see above) and/or behavioral methods such as deep breathing.
Another way to help you manage stress is to think through future stressful situations to be better prepared. Afterdeployment.org suggests: 1. Visualize potential stressful situations. 2. Determine how much of the situation you can control. 3. Problem-solve what you can control (using coping methods that work for you), and 4. Remember to lean on your friends and family for support.

If you’ve ever thought you noticed a boost in energy while using your electronic gadgets, it may not just be in your head. A recent study suggests that blue light—the type that’s emitted from all electronic devices and energy-efficient light bulbs—can give you an energy boost equal to or better than two cups of coffee. The same study makes a connection between blue light and enhanced sports performance. Sounds great, right? But what if sleep is the missing piece of your performance puzzle?
While you might welcome an energy boost during the day, using electronic gadgets at night can be detrimental to your sleep health, disrupting your natural circadian rhythm by suppressing the secretion of melatonin, a powerful sleep hormone. Follow these tips to manage your exposure to blue light:
- Take advantage of electronic devices during the day to boost your attention, reaction times, and mood.
- Shut off all electronic devices at night at least two hours before you go to bed.
- Consider wearing blue-blocking glasses on those nights when you can’t avoid blue light.
- Use dim, red lights if you like having a nightlight. Red light has less impact on your melatonin levels. (Parents also take note for the nightlight in your child’s bedroom.)
One more tip about light: During the day, get plenty of bright daylight. Not only will it make you feel better during the day, it will also help you sleep at night.
