Post-Traumatic Stress Disorder (PTSD) can tear apart your sense of what is safe and of what is good.
Part of the diagnosis of PTSD is exposure to a traumatic event: death, serious injury, sexual violence, or the threat of any of these. PTSD symptoms such as intrusive memories, avoidance of situations or feelings, problems in thinking or mood, and feeling overly amped up are common reactions to abnormal circumstances. Think of PTSD symptoms as self-preservation instincts gone haywire. One theory holds that, because you nearly died or experienced something awful or could picture it because it happened to someone close to you, your mind/body tries to sound the alarm bells to keep you safe. But the alarm bells sound at the wrong times and in the wrong ways.
However, PTSD symptoms can come from sources other than fear of bodily harm. They also can arise from inner conflict, when emotions trigger feelings such shame and guilt or when you question fundamental beliefs (such as “the world is basically good”). Witnessing or experiencing betrayal (especially by a leader in a high-stakes situation), within-ranks violence, extreme violence, and incidents involving civilians are some of what can disrupt your world view. It isn’t just an event but the interpretation of an event that causes Warfighters to experience “moral injury.”
If you suffer moral injury as part of PTSD, you start believing you live in an immoral world, or you view yourself as immoral, irredeemable, and defective. If you’re a Warfighter experiencing these feelings, you not only feel lousy, but you are more likely to isolate yourself just when you need others more than ever. Isolation can lead to self-handicapping or self-destructive behaviors.
So how do you save yourself from experiencing moral injury as a part of PTSD? Having a healthy sense of self-esteem can be one of your best protectors. There are no quick fixes. But forgiveness—of others and of yourself—can help you to let go of moral injury. With the help of a psychotherapist, you can begin to wrap your heart and mind around what happened. And pursuing positive interactions, such as getting involved with charitable groups, can give you opportunities to relearn that you are good and the other people in the world are generally good too. Last but not least, connecting with your spirituality—in whatever way is comfortable to you—can help you navigate this difficult journey.
Training for a marathon or some other endurance event? Building your endurance—by making the right nutrition choices—can make the difference between failure and success. HPRC’s performance nutrition strategies—“Going the distance”—provide the information you need to know what and when to eat for endurance.
Relationships are important to total fitness—especially intimate relationships. Think back to the beginning of your relationship—was it filled with lots of passion and intensity? Does it still have those aspects?
There’s been a lot written about the different types of romantic love, and how they change over time. One theory describes two main types of love: passionate and companionate. Passionate love involves an intense feeling of longing for one another. Companionate love happens when you feel affection, tenderness, intimacy, and commitment to your partner. Couples with companionate love often also feel a deep mutual friendship, an ease of companionship and a sharing of common interests. Companionate love does not have to include being attracted to each other or sexual desire.
It’s generally thought that couples begin in passionate love and later morph into companionate love. However, research suggests that romantic love that has intensity, interest, and passion can grow and flourish in relationships over the long run. As with diet and physical fitness, moderation is key. Focus (but don’t fixate) on your partner and foster affection, intimacy (both physical and emotional), and a deep bond. It is possible to be with your partner for a long time—and still experience passion and emotional intimacy with him or her! So set the bar high and strive for it. It is not a myth!
Activity monitors have become increasingly popular tools to help people get and stay on track with their fitness (and dietary) goals. But, researchers from Iowa State University wanted to see just how accurate some of the popular monitors really are when it comes to reporting how many calories you burn during exercise. It turns out that the majority of the devices they tested gave pretty accurate estimates (within 10-15% error). The BodyMedia FIT was the most accurate one tested, with only a 9.3% error rating, which is close to some more expensive devices used for research purposes. Other monitors such as the FitBit Zip, FitBit One, Jawbone Up, and Nike Fuel Band all fell below 15%. Since many people tend to overestimate their activity levels on their own, an accurate activity monitor is an important tool to help people keep better track of their exercise habits. Check out our comparison chart to find out more about these monitors.
Whatever else you have planned for the 4th of July, take a moment to reflect on what this celebration signifies and what we owe to our nation’s service members past and present for making and keeping this national holiday special.
Did you know some of our services are even older than our country? The U.S. Army was established on 14 June 1775, more than a year before our official separation from Great Britain. The U.S. Navy dates to just four months later, on 13 October 1775, with the Marine Corps created as part of the Navy on 10 November the same year.
Although the declaration that established the nation was still a year off, the Second Continental Congress in Philadelphia acted to organize and fund the amateur troops that had formed in New England, making General George Washington the first commander-in-chief of the Continental Army on 3 July 1775.
The Navy originated in a similar fashion, through an act of the Continental Congress. Just two armed ships made up the initial fleet, which grew to roughly 20 active warships during the Revolutionary War. Two battalions of Marines were called for shortly after the fleet was initiated.
And so as you celebrate this national holiday, take a moment to remember those Warfighters who helped establish our country as well as those who have helped maintain it through more than 238 Independence Days. And thank those who are still doing so today!
E-cigarettes were introduced to help people stop smoking, but they are becoming a popular alternative to traditional cigarettes. But are they really a healthier substitute, as many companies claim? In short, we don’t yet have a full answer to this important question, and the U.S. Food and Drug Administration (FDA) is on a mission to find out.
On April 25th, FDA released a proposal for new regulations on e-cigarettes—a multibillion-dollar industry that so far has not been highly regulated. In fact, FDA currently lacks the authority to collect vital information about these products. Traditional cigarettes deliver thousands of chemicals, many of which are dangerous, to cigarette smokers and non-smokers around them. By comparison, e-cigarettes deliver substantially fewer chemicals. However, little is known about the potential dangers of the chemicals that e-cigs deliver.
Proposed new rules would allow FDA to collect information about the ingredients in e-cigarettes, as well as their health and behavioral effects. It also suggests that more research is needed to study the long-term health effects of these products.
E-cigarettes are now being marketed with flavors popular among young people. Preliminary studies have found that young people who say they would never use a tobacco product are experimenting with e-cigarettes. The proposed new rules also would require e-cigarette users to be at least 18 years of age to purchase these products.
Although it’s still unclear how the popularity of e-cigarettes will impact public health, but it’s certain that more research will shed some light on their long-term effects.
HPRC has written several articles about energy drinks, their ingredients, and their potential harmful effects, especially for adolescents. They continue to be the topic of news articles, with another recent death of a teen who apparently consumed several energy drinks while on vacation and then died from cardiac arrest. The American Association of Poison Control Centers (AAPCC) urges the public to use caution when consuming energy drinks and lists many potential harmful reactions. Read more on this AAPCC web page, including statistics on reports of “exposures” to energy drinks.
HPRC has an Infosheet on energy drinks, highlighting the ingredients you may find on labels,and their potential stimulant effects. Be aware of the potential dangers, especially for children and teens, as outlined by the American Academy of Pediatrics.
Problem solving is a great resilience skill for families. All ages can learn or fine-tune their ability to solve problems. After all, life ensures there will be plenty of problems to solve! You can specifically help children learn how to problem solve with this easy-to-remember acronym—SNAP:
S: State the problem.
N: Name the goal.
A: Find All possible solutions.
P: Pick one option.
For example, if your child wakes up tired every morning, you can help him or her identify the problem (being tired), set the goal of getting more sleep, and discuss possible solutions (such as going to bed earlier, developing a bedtime routine, or learning a relaxation skill such as deep breathing). Then help your child pick one to try for a specific time period (such as a week) to see if it works. And instead of trying to solve the problem yourself, be a coach and help your child learn how to solve problems using SNAP.
You’ve probably seen the pictures on social media and in the news: a very pregnant woman, with a heavy barbell on her shoulders, mid squat, in an Olympic powerlifting move. But is it safe for mother and baby? If this is a situation you might find yourself in, and/or you’ve talked to your doctor about a pregnancy exercise regimen, there are some things you should know about weight lifting and exercise. Read HPRC’s “Lifting weights during pregnancy” for more information.
