During deployment, the parent at home plays a pivotal role in providing support for their children. Recognizing signs of deployment-related stress allows you to intervene and prevent future concerns. In young children, signs include unexplained crying, sleep difficulties, eating difficulties, and fear of new people or situations. In adolescents, signs include acting out, misdirected anger, and loss of interest in hobbies. For more signs of distress, read this Military.com article.

The U.S. Centers for Disease Control (CDC) has published a new study reporting four lifestyle factors that are linked to a healthier and longer life. The CDC suggests that people keep or adopt the following lifestyle behaviors: Don’t smoke, limit daily consumption of alcohol, exercise regularly, and make healthier eating choices. Read more about how these lifestyle factors can lead to a healthier life.
If you’ve ever switched times zones, even as little as one hour, you may be aware that it can disturb your sleep and even disorient you in the following days. Without taking any medicinal countermeasures, you can typically adapt to your new time zone with about one hour of extra sleep per day after arrival (depending on with direction you’re traveling). However, some operations require that you be able to perform within 24 hours of arrival. To better prepare and adjust to your new time zone, use these strategies:
- One week before you travel, adjust your sleep schedule about one hour per night towards the time zone you are flying in—i.e., if flying eastward, go to bed and get up earlier; if flying westward, sleep later.
- Before you take off and while on the aircraft, eat light snacks, avoid alcohol, and stay hydrated (with water).
- On the aircraft, make sure that you are comfortable and able to nap before you arrive at your destination.
- Setting your watch to your new time zone as soon as you board your flight will help you transition.
- Take a short nap when you arrive at your new location, if you’re able to do so.

When my own husband returned from deployment, I was thrilled but anxious as I stood on the airstrip waiting for his helicopter to arrive. I thought about all of the birthdays, holidays, and special events he had missed during his time away. I wondered what it would be like to share a home with him again after I had become so independent.
This is an experience felt at some point by most military families, and it has a name: “boundary ambiguity.” Boundary ambiguity can affect military families in two ways: ambiguous absence (during deployment) and ambiguous presence (post-deployment).
When one member of the family is deployed, the rest of the family knows that their service member is absent physically but senses psychologically that he or she is present. The family continues to focus on its service member by seeking information about his or her location and well-being. When deployment information turns out to be uncertain, feelings of hopelessness, confusion, and at times resentment may increase among family members.
As with most families, flexibility is important for military family success and happiness. When the service member leaves for deployment, the usual roles and responsibilities he or she once filled now have to be filled by the other family members. This can cause additional uncertainty because, although they still consider their loved one is a viable family member, the other spouse must take over decision-making responsibilities that affect the family unit. The spouse at home can also feel a loss of emotional support, which heightens the stress load he or she is carrying.
Additionally, once the service member has returned from deployment, the rest of the family knows that he or she is physically present yet still perceives psychologically that he or she is absent.
The reunion, although joyful, may bring about the added and unanticipated stresses of trying to get back to the family’s pre-deployment lives or adjust to new roles. Role confusion may increase if the family is not comfortable communicating with each other regarding each person's roles, responsibilities, and needs. And at the same time, the returned service member may feel disconnected and may not know how to re-engage without interfering with the family’s new roles.
Researchers of military reserve families in wartime interviewed 16 reservists and 18 family members (spouse, significant other, or parent) upon the reservists’ return from deployment, and they found that all family members experienced boundary ambiguity. Family members sought to cope with these feelings during deployment by:
- Continuing to seek additional information from the media, even though too much information sometimes caused additional stress; and
- Attending a military-sponsored Family Support Group (FSG) for family members of reservists, which provided emotional support.
When reunited after deployment, family members and reservists adjusted over time. Once the reservist went back to civilian employment, the family’s routines became “normalized” and roles were established. In addition, open communication about issues such as reestablishing previous tasks or assigning new ones helped to stabilize the family unit.
Once home, my husband wanted to resume certain family roles immediately, while I was hesitant to give up my new capabilities so quickly. Fortunately, after reestablishing open discussions over the next several weeks, we began to speak honestly about our preferences. Once we opened up clear lines of communication and listened to each other, our stress levels diminished. We made some compromises and were able to establish an even better household environment than we had pre-deployment.
So be flexible, take advantage of available counseling and support resources, and be patient with your spouse when reestablishing your family roles. After all, there aren’t many things more important than the happiness of your family.
Most people understand what it means to have high blood pressure, excess fat around the middle, a high cholesterol level, and the importance of addressing these health problems. What some may not realize is how serious the situation becomes when a person has been diagnosed with three or more such conditions in conjunction with other health issues.
This occurrence is called metabolic syndrome.
People who suffer from this combination of conditions (a reported one in four—50 million in the United States alone) have a dramatically increased risk for developing heart disease, type-2 diabetes, or a stroke. Individually, these symptoms pose a health risk, but identified together they raise the risk for cardiovascular disease.
Metabolic syndrome is characterized by a cluster of symptoms that include excess fat in the abdominal area (as measured by waist circumference), borderline or high blood pressure, high cholesterol that fosters plaque buildup in arteries, insulin resistance or glucose intolerance indicating the body can’t properly use insulin, raising blood sugar levels, and the presence of a protein in the blood, which can cause inflammation.
People with metabolic syndrome have at least three of the following risk factors:
- Excessive body fat around the waist
- Low levels of HDL ("good") cholesterol
- High levels of triglycerides (a type of blood fat)
- Elevated blood pressure
- Elevated glucose (blood sugar) levels after fasting
The complications of metabolic syndrome are serious and, if not addressed, can cause major health problems. If you are overweight and don't yet have these problems, keep in mind that the older you get, the more likely you are to develop them. Older adults can develop metabolic syndrome without being overweight, so it is important to get annual physical exams.
What can be done to prevent metabolic syndrome? If you are fall into the categories above or are overweight, one way to reduce your risk of metabolic syndrome is to incorporate healthy habits such as starting an exercise regimen. (But be sure to consult your doctor before starting a new exercise program, especially if you have not been active for a while.)
Diet is also key to reducing the risk of metabolic syndrome. By making small changes in your diet—such as decreasing the number of calories you take in per day; eating more fruits, vegetables, whole grain products, and low-fat meals, and avoiding fast/fried/fatty/oily foods—you can reduce your chances of developing metabolic syndrome.

Follow these tips to help your child cope with a parent’s deployment:
1) Increase your knowledge/awareness of deployment-related issues.
- Understand the various ways in which a family is affected by deployment.
- Understand the stages of the deployment cycle.
- Find ways to improve public awareness of the need for support within communities.
2) Increase your knowledge of and vigilance for depression and stress symptoms:
- Learn to recognize signs and symptoms of depression and other mental health concerns.
- Understand common emotional phases in children and teenagers during times of deployment.
3) Increase opportunities for connection and support:
- Show concern for your child. Many teens will refuse to express their concern over a deployment but will often respond to concern shown for them.
- Help kids form networks with peers who have gone through or are going through a parent’s deployment.
- Provide opportunities for activities to keep children distracted.

According to an Associated Press article from August 2, 2011, the Food and Drug Administration (FDA) has warned the manufacturer of the melatonin-laced brownies known as "Lazy Cakes" that the government considers them unsafe and could seize them from store shelves. The brownies were originally sold under the name Lazy Cakes, but the manufacturer of the product has changed the product name to Lazy Larry.
The FDA said that melatonin has not been found to be safe for use in conventional foods. “On the contrary, reports in the scientific literature have raised safety concerns about the use of melatonin,” said the letter, sent last Thursday by the agency’s acting director for the Office of Compliance. Melatonin is not approved for use in any food, the FDA said.
HBB, LCC, the Memphis-based company that makes Lazy Cakes/Lazy Larry, was given 15 days to respond to the FDA with details on specific steps it would take to correct its violation of the ban against melatonin use in food.
It should be noted that the HPRC has been covering Lazy Cakes since they first became available.
Interval training alternates high-intensity movements such as running or cycling sprints with a recovery phase that consists of rest or low-intensity movement such as walking or slow cycling. Interval training improves your cardiovascular fitness, ability to burn fat, and ability to tolerate lactic acid build-up while lowering your risk for cardiovascular disease. Overall, adaptations from interval training can lead to improvements in strength, speed, and endurance while improving your body composition. Interval training is a .
A basic interval training session could include sprinting on the straightaways (100m) of a standard track and walking the curved portion (100m). Or alternate 30-second bouts of high-intensity exercise with recovery bouts. Initially, start with rest periods longer than the work periods, and work up to equal time periods as your fitness improves. If you are out of shape, have health problems, high blood pressure, or joint problems, check with your physician before starting a high-intensity training program.

During times of deployment, children and teenagers often look for support from the people in their lives—family, teachers, and friends—to help them deal with the stress of having a parent deployed. A good support system helps by listening, understanding, and providing comfort. Children often will respond to those who show concern for them and to those who understand life in the military. Provide support by listening to what your child has to say and by helping them understand their situation.
