Virtual reality was first introduced as a therapy tool for people with anxiety disorders such as phobias, but it is now used for a wide range of conditions, from PTSD to childhood ADHD. In fact, it recently warranted its own symposium at Walter Reed National Military Medical Center, where experts exchanged ideas on the current state of research.
Virtual environments used in therapy sessions are created for the individual’s needs—for example, a noisy classroom for a child with ADHD, the re-creation of the 9/11 attacks for a firefighter or police officer, or “Virtual Iraq” for a soldier. “Virtual Afghanistan” is the newest creation and is already being used to help service members overcome PTSD. Active-duty men and women are gradually brought back to their traumatic event using the virtual world as the therapist provides verbal cues to facilitate the healing process.
With a view to mitigating future need for therapy, a series of episodes is currently being created to provide pre-deployment “Stress Resilience Training for Warfighters.” The goal is to help reduce the risk of PTSD and better prepare warriors for actual scenarios they will encounter in theater.

Preventing obesity should begin at an early age, because children who are overweight often become obese as adults. And while many of us know that we need to eat right and exercise, there are also risk factors that we are born with that we can’t change. Now you can calculate your child’s risk of developing obesity with an online calculator.
The calculator was developed by a team of researchers who looked at a number of well-known biological and social risk factors for developing obesity. They were able to boil down their findings to six simple factors that provide a reasonably accurate probability of whether a child will develop obesity:
1) The body mass indexes (BMIs) of both parents. (HPRC has a link to a calculator you can use to calculate BMI.)
2) The number of people who live in the house.
3) What kind of work the child’s mother does.
4) Whether the mother smoked during her pregnancy.
5) The birth weight of the child (in kilograms). (To convert pounds [lb] to kilograms [kg], multiply pounds by 0.45359237.)
Living a healthy lifestyle is beneficial for everyone, but tools like this can help you determine whether your child is particularly at risk for becoming an obese adult, so that you can make important health changes early in life.

Lugging around heavy weights and other exercise equipment while traveling or on deployment isn’t the most practical idea. Pack a couple of suspension-training straps, however, and you’ve got part of a well-rounded training routine covered. Suspension training has gained a lot of popularity among both civilians and service members alike, and more and more gyms are now offering suspension-training classes. Once the straps are securely anchored to something that won’t move and is sturdy enough to hold your weight, place your hands or feet into the loops, and your body weight enhances the effectiveness of exercises such as push-ups, lunges, core strengthening, and more. While there are various ways to adjust and adapt the exercises for less experienced exercisers, this type of workout requires some initial joint and core stability. There is also potential risk of injury, especially for beginners. Before you try this for the first time, it’s a good idea to get some advice and guidance from a suspension-training professional.
The physical and emotional stress associated with post-traumatic stress disorder (PTSD) can raise your blood pressure and cholesterol and increase body mass index, all of which are risk factors for heart disease. Veterans suffering from PTSD are more than twice as likely to die from a heart attack than those without PTSD. While the exact relationship between PTSD and heart disease is not fully understood, we know that regular exercise can help prevent heart disease and other risk factors, which could be helpful for those with PTSD. Some types of exercise can be effective in reducing psychological symptoms associated with PTSD and also can play a role in reducing unhealthy behaviors such as smoking, being overweight, and physical inactivity—sometimes byproducts of trying to cope. If you think that exercise might help you or a loved one cope with PTSD, speak with your healthcare provider to assess how much and what kind of exercise is best!
At some point or another, your child or teen might pick up those dumbbells you have lying around the house. They’ve seen you lift weights as part of your regular exercise routine and decided they want to get stronger too. But you might wonder if strength training is safe for your kids.
Lifting the size weights you use might be too much for kids and teens, but in general strength training (also referred to as resistance training) can be a safe and healthy way to improve muscular fitness for children and teens, starting as early as seven or eight years old, when their coordination skills have developed enough. The goal should be improving muscular fitness while having fun and learning effective training methods.
As a parent you need to make sure your kids are supervised and receiving age-appropriate and skilled instructions in order to reduce the risk of injury. With proper technique and safe practices, strength training is not dangerous for growing bodies. However, light weights, exercise bands, or your child’s own body weight should be used to build his or her strength. Currently, there are no specific guidelines for exactly how much lifting they should do. However, according to the American College of Sports Medicine (ACSM) one to three sets of six to 15 repetitions, two to three times per week is considered reasonable.
Resistance training is not the same as bodybuilding, weightlifting, or powerlifting, which are associated with competition, high intensity, and maximum weights. The American Academy of Pediatrics and ACSM are opposed to children using these methods or the use of "one-rep-max" (a method sometimes used to assess strength) due to the increased risk for injury.
While a medical examination is not mandatory, it is recommended for children who want to begin a strength-training program. And remember that strength training is something you can do with your children. Family fitness is a great way to keep you and your child healthy and active while you spend quality time together.
