Reconnecting with your family when you return from deployment presents unique challenges, especially with young children. Depending on how long you were deployed—a few months to a year or more—a lot could have happened in your child’s life while you were away. If you’re finding it hard to reconnect with your child, you’re not alone. Military Parenting’s website has tip sheets that describe typical behaviors for different stages: infant, toddler, preschooler, school-aged, and teen. Just knowing what’s typical for you child’s age can help you reestablish your relationship.
Reconnection can occur in small, everyday moments when you respond to your children’s needs and provide them with support and nurturing, such as holding them when they cry, playing games or sports together, being silly and laughing, taking a walk together, or eating dinner together and talking about your day.

More than two million new cases of skin cancer are diagnosed each year, and the number is growing. Skin cancer is a major public health issue, and with proper precautions you can decrease your risk considerably. Hopefully this information on sun safety will help you, whether you are a Warfighter or dependent, stay safe during all outdoor activities!
Ultraviolet radiation (UVR) has been identified as the most important risk factor for both melanoma and non-melanoma skin cancer. Exposure to UVR weakens the skin’s elasticity and can result in sagging cheeks, deeper facial wrinkles, skin discoloration, burn, skin aging, photosensitivity, and cancer. Taking steps to safeguard yourself is crucial, especially when participating in outdoor activities or exercising.
Sweating increases the skin’s sensitivity to the sun’s rays, magnifying the risk of sunburn and skin damage. Athletes who practice outdoor sports have been found to be at increased risk for skin cancer. Remember—the weather does not have to be sunny and hot for you to get sun damage. Ultraviolet rays penetrate clouds, exposing you to 80% of the UVR. Even skiers and mountain climbers are at risk for sun exposure and skin cancer because of the stronger UVR at altitude.
Follow these precautions from the Occupational Safety and Health Administration (OSHA) whether training for the PRT, patrolling, road marching, or participating in a summer league softball game:
Avoid burning. Avoid sun tanning. Also, try to avoid sun exposure during midday (11 a.m. to 3 p.m.) when the rays are the strongest.
Seek shade. When possible, especially during midday, seek shade under a tree or tent.
Cover up. Wear protective clothing, including hats, long-sleeved shirts, and pants when going outdoors. Keep in mind protection decreases when clothes are wet.
Use extra caution near water, snow, and sand. Ultraviolet rays can reflect off of these surfaces, which can increase your chance of sun exposure and skin damage.
Apply sunscreen. Use water-resistant sunscreen and apply 15-30 minutes prior to sun exposure to allow for it to absorb. Also, reapply after swimming, sweating, or toweling off. Be sure to take a look at the new FDA regulations regarding sunscreens and their effectiveness.
Wear sunglasses. Protect your eyes when working, driving, participating in sports, taking a walk, or running an errand. Solar ultraviolet B radiation can cause an increased risk of cataracts and cancer of the skin around the eye without proper cover.
It’s always important to remember hydration when engaging in outdoor activities as well! HPRC has useful tips on hydration and the consumption of sports drinks and caffeine during exercise in the heat.
Coconut water, the flavorful liquid found in young green coconuts, has become a popular drink. It is often promoted for a variety of ailments—from curing bad skin to resolving hangovers. But coconut water is also touted as a fluid replacement alternative. For this reason, some Warfighters choose coconut water over sports beverages because coconut water is “natural” and contains carbohydrates and key electrolytes such as sodium and potassium. However, not all brands of coconut water are created equal. In fact, they can vary considerably in terms of their nutrient content, so read product labels to be sure you’re getting the right amount of nutrients you need for optimal performance.
For example, the amount of carbohydrate and sodium in coconut water is sometimes very low, and individuals who participate in prolonged, vigorous exercise (longer than an hour) may need more carbohydrate and sodium. On the other hand, the potassium content of coconut water can be very high. Drinking a lot of coconut water (more than 8–10 servings in one day), especially if you eat potassium-rich foods such as bananas, can raise your body’s potassium levels too much, which can cause heart problems for some people. For more information about hydration needs, see HPRC’s article on fluids and exercise.
For periods of exercise less than one hour, water is always your best choice—about 7–10 ounces every 15–20 minutes. But for longer periods of exercise, sports beverages are a good choice because they are specially formulated to replenish carbohydrate, sodium, and potassium lost during extended and/or vigorous physical activity. Again, be sure to read the product label to make sure yours has what you need, and nothing more. If you choose sports beverages, drink three to eight ounces every 15–20 minutes to stay hydrated. For more information about proper hydration, read An Athlete’s Guide to Nutrient Timing.
And what about that coconut water? There simply isn’t enough evidence to support the use of coconut water as a remedy for any condition. And although it’s a tasty beverage, know what’s in it so you can replenish what your body needs—no more, no less.
Listening is half of communication. The other half is what you say and how you say it. The best way to express yourself is to be assertive. Assertive communication feels neither aggressive nor passive. It’s a balance between issuing a directive and being overly cooperative.
Communication between siblings can provide some good examples. Here’s the super directive approach: “You need to call me too. Don’t make me do all the work to keep up our relationship.” That may make sense, but the other person may not take it in because it triggers defensiveness. And here’s the overly cooperative approach: When your sibling says, “I hope you don’t mind that I never call,” you reply, “No, it’s okay, whatever you want is fine” (even if it isn’t). An assertive approach would be: “I’d really like to talk with you on the phone more, and I know you’re busy. What can we do to stay in better contact?”
The approach is basically a combination of “This is what I need” and “Can you join my team in figuring out a solution?” It’s straightforward and mutually empowering, opening the door for real communication. And for the other half of the communication equation, read last week’s article about how to be a good listener.
Today is Memorial Day. Memorial Day began as “Decoration Day” after the Civil War. In 1882, Decoration Day became widely known as Memorial Day, and after WWII it became a day to remember all our fallen heroes, not just those from the Civil War. In 1967, Congress passed the law making it an official holiday to be celebrated on May 30, subsequently changed to the last Monday of May. We at HPRC extend our greatest appreciation to those who have perished for our nation and offer our sincere sympathy for the families left behind. There are many ways people choose to remember those who gave their lives as a supreme sacrifice to our country and its ideals. HPRC is dedicated to providing our Warfighters and their families the information they need to build resilience to prevent injury and illness and carry out their missions as safely and effectively as possible. Our desire is to reduce the level of sacrifice our warriors have to make as they fulfill their future missions for us and for our nation.
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.
