Depression—Don’t tackle it alone

HPRC Fitness Arena: Mind Tactics, Total Force Fitness
Depression isn’t just a lousy mood—it’s a serious illness that needs serious help. Check out some of the special resources for service members, whether it’s for you, a buddy, or a family member.

We’ve all heard of depression. If you’ve never experienced it, it’s easy to think that someone could just snap out of it if they wanted to. Depression doesn’t work like that. It can have an impact on a person in every way—physically, mentally, and emotionally, even extending to relationships—and can range from mild to severe. According to the American Psychological Association, “Depression is more than just sadness. People with depression may experience a lack of interest and pleasure in daily activities, significant weight loss or gain, insomnia or excessive sleeping, lack of energy, inability to concentrate, feelings of worthlessness or excessive guilt and recurrent thoughts of death or suicide.” Depression is an illness considered to be treatable with professional help.

This factsheet from afterdeployment.org details the signs and symptoms of depression. They also have an anonymous online assessment, general information, personal stories shared by those who’ve experienced depression, an interactive workbook that can help you challenge negative thoughts and identify depression triggers, and information about the link between behaviors and mood. Also take a look at the factsheet on Taking Charge of Depression, which includes helpful strategies.

For more information about depression or other mental states that can influence your performance, check out the section of HPRC’s website on depression. However, if you feel you are in crisis, contact the Military Crisis Line—someone is available 24/7 for online chat or via phone at 1-800-273-TALK.

Cope with emotions through mindfulness

Mindfulness helps you to face hard emotions instead of running from them. Learn how here.

Mindfulness can help you feel better equipped to handle difficult emotions. It’s a process geared to help you tune into emotional experiences rather than try to escape from them. People can feel overcome by depression, anxiety, PTSD, addiction, or other mental health problems, which, ironically, can be exacerbated by trying to forget the cause. For example, a Warfighter afflicted with PTSD often relives difficult events through dreams, flashbacks, or unwanted memories, because he/she desperately wants to avoid experiencing those events. To illustrate this idea, right now, try NOT to think of weapons. You probably thought about them that much more.

Practicing mindfulness mediation means focusing on whatever you are experiencing in the present moment. It can be a structured meditation activity, but because mindfulness is about being present, you can purposefully engage in mindfulness anytime, anywhere. A common meditative approach is to focus on a physical experience such as your breathing, noticing where your attention wanders, and gently guiding it back to your breath; it allows you to experience sadness, anger, fear, and other unpleasant emotions, letting them pass without clinging to the idea of making them go away.”

If you have ever “white-knuckled” your way through an amusement park ride (or ridden in a car with a driver you didn’t trust), you may remember thinking, “When will this be over? Please let it be over…” This shows that focusing on how long something lasts can make it feel like an eternity. By engaging in mindfulness, you will feel less threatened by certain emotions, and you will be less likely to engage in problematic forms of escape (such as drinking, drugs, or simply spacing out).

When people experience difficult emotions, they often cope by engaging the language center of the brain, using words internally to wrestle with the experience. But when people have difficulty re-evaluating why they feel the way they do, this leads to a circular internal debate (such as “I shouldn’t feel this way, but I do, but I shouldn’t…”), which can be pointless and can actually cause more distress. Emotions can be dealt with not just through words but also by tapping into their physical elements (noticing how you feel in your body). When people engage in regular mindfulness practice, the parts of their brains tuned into physical sensations are activated while they experience hard emotions. And people who regularly have this part of their brain activated tend to be more emotionally steady.

Unfortunately, it’s difficult to escape unwanted emotions. And more problems will probably pop up as you try to escape. But if you’re willing to face hard emotions, letting them come and go like waves on a beach, then mindfulness practice can help you have a different experience. Tune in to HPRC for more mindfulness resources, and take advantage of the fact that mindfulness is everywhere now, whether part of your martial arts or yoga class or filling the self-help shelves of your local bookstore. Become more mindful, and you can feel better equipped to handle tough emotions; your mind and body will engage them more productively.

No pain, no gain?

Higher-intensity exercise—does it do a body good?

The saying goes that “less is more,” but when it comes to exercise intensity, that might not be the case. We know that some exercise is better than no exercise, but is more-intense exercise better than moderate exercise? How hard should you push? And what are the benefits? With the growing popularity of high-intensity workouts, it’s important to consider both the risks and the benefits.

The role of intensity during exercise has been studied before. For example, the risk of death in older adults is lower for those who walk at a faster pace than for those who walk at a more leisurely pace. However, new research demonstrates that pushing yourself during a workout not only helps make you mentally tough but may also release chemicals into your body that help you develop bigger, stronger muscles.

During “stressful” or high-intensity exercise, your body kicks into “fight or flight” mode and releases hormones such as adrenaline and dopamine to push your system into high gear: increased heart rate, increased breathing rate, and increased oxygen to muscles. A recent study found that these hormones, when released during stressful exercise, sent messages to muscle cells to develop larger and more efficient muscles—at least in mice. The body only releases these chemicals when it feels stressed (for example, during intense exercise). If the body doesn’t feel stressed (as during light exercise), it doesn’t release these chemicals, so it can’t send signals to the muscles.

The good news is that exercise intensity is relative, so anyone should be able to exercise at a level that releases these hormones. Whether you’re just starting out or you’re a seasoned athlete, you can exercise to a level that is intense for you. Shooting for your target heart rate is a good start to gauging intensity. Not every workout needs to top out the intensity scale. In fact, doing too much too often can lead to overtraining and potential injury. Remember to listen to your body and incorporate rest or light days into your workout regimen. 

To communicate, don’t triangulate!

If you want to communicate more effectively, at work or at home, learn how to avoid the pitfall of triangulation.

Whether you know it or not, you’ve probably engaged in “triangulation,” and not just as a kid when you ran to Mom because Dad just said “no” (or vice versa). Similar triangles can also happen with leadership or any work group, committee, or organization (including military) where two people talk about a third.

On the surface, triangulation can look pretty harmless. You vent out of frustration because someone is not acting the way you’d like. Depending on where you are in the triangle, you either receive sympathy or provide it, possibly exerting any power you have to fix the situation. These triangles tend to consist of a “victim,” a “villain,” and a “rescuer.”

Because people are often uncomfortable with conflict, they figure out ways to maintain the status quo, even if it’s a bad one, instead of addressing what the core issue is. Triangulation is one way to avoid facing things, and it can feel like a fix, but it’s temporary at best. The rescuer provides a sympathetic ear so that the victim doesn’t feel a need to take action, or tries to take charge of the situation, but inevitably, the same problems pop up between the original two people.

Next time you feel like a victim and consider going to another person with your conflict, first be clear about your goals. Do you want to be rescued, or do you want to be coached? Before reaching out, ask yourself if you can possibly self-coach your way through whatever is popping up. Prepare yourself for whatever criticism might come your way if the “villain’s” defenses get triggered. And “preparing” does not mean bracing yourself or getting ammunition ready to fire back at that person. It means getting ready to really listen and validate how the other person feels, even if you don’t agree with the content of what that person says. If that person feels listened to, he/she will become more receptive to your position.

When a triangle does occur, the best scenario for the third person (the potential rescuer) is to be a good coach. Coaches don’t play the game for their players; they help them become more self-sufficient. Similarly, good leaders ask challenging questions of the people under their command, helping them to think through situations and become better equipped to face conflict directly. If you’re the potential rescuer, resist your own impulses to fix things and instead work on enabling the victim to fix the situation directly. Know that if you dive into this triangle, any other solution is probably temporary at best.

These strategies may seem simple, but they take practice. Try letting go of triangles and use some of the same kinds of communication strategies that work for couples. 

PTSD can “short-circuit” your brain

Filed under: Mind, Mind tactics, PTSD
PTSD affects the “circuitry” of the brain. Learn how PTSD-affected brains confuse threat and safety.

PTSD was finally recognized as a medical condition when recent advances in neuroscience showed that the brain no longer works properly after trauma. Your brain has an alarm system to help ensure your survival; it’s useful as long as it works properly. When the alarm system malfunctions because traumatic events pushed it to its limits, the part of the brain responsible for thinking and memory can’t function properly. When this happens, a person with PTSD can’t compare what’s happening now with events in the past when they were safe. However, there are treatments to help “rewire” the brain, so it can work properly again. Learn more about this in “How is your brain’s circuitry affected by PTSD?”

Happy 224th, U.S. Coast Guard!

HPRC Fitness Arena: Total Force Fitness
In honor of the anniversary of USCG, take a moment to learn a little about the background and mission of this essential branch of the U.S. armed forces.

On the 4th of August 2014, the United States Coast Guard will be 224 years old. The Coast Guard actually began as the Revenue-Marine, later renamed the Revenue Cutter Service, under the Department of the Treasury. Its original mission was to control the seagoing smuggling that was rampant in the years following the founding of the United States. Needing money to fuel the fledgling country, the Treasury used the Revenue Cutter Service to patrol the shores and ensure that importers paid tariffs on their goods.

For its first eight years, following founding in 1790, this was the U.S.’s only maritime armed service because the Navy had been disbanded after the Revolutionary War. During the War of 1812, after the Navy had been re-formed, the Revenue-Marine was put into military service under command of the Navy. This set a precedent in which the Cutter Service alternated between peacetime missions under the Treasury to control shoreline smuggling and piracy and wartime military operations under the Navy.

The U.S. Life-Saving Service was also part of USCG’s ancestry. Founded in 1848, this agency grew out of a Massachusetts volunteer service, whose aim was to help shipwrecked mariners. The Service operated out of shore-based stations that spread southwards from New England after the Great Carolina Hurricane of 1854 brought recognition and federal funding. In 1878, the Life-Saving Service was formed as a federal agency under the Department of the Treasury.

In 1915, the Revenue Cutter Service and the Life-Saving Service merged to form the United States Coast Guard, which later absorbed other marine-related Treasury agencies. Its scope expanded to cover smuggling, maritime rescue, shipping regulation, and wartime naval combat support and coastal protection. In 2003, the Coast Guard’s protective position was brought to the fore when it was transferred to the Department of Homeland Security.

This August 4th, take a moment to thank the members of our U.S. Coast Guard for all they do!

FDA’s warning on caffeine powder

FDA issues a warning about caffeine powder and advises consumers to avoid powdered pure caffeine.

The Food and Drug Administration (FDA) is warning consumers about powdered pure caffeine, particularly as sold in bulk on the Internet. At least one death has been associated with the use of such products, and FDA advises consumers about the potency of powdered pure caffeine. See FDA’s Consumer Advice, which includes information about how to report an adverse event.

According to this consumer resource from FDA, you should limit your caffeine intake to just 100–200 mg per day (about 5–10 ounces of coffee). Taking large doses of caffeine—roughly 400–500 mg—at one time can result in a serious condition known as “caffeine intoxication.” Some symptoms of caffeine intoxication are minor and include nausea, vomiting, agitation, nervousness, or headache. Other symptoms can be more life-threatening, such as rapid heartbeat, electrolyte imbalance, very high blood sugar, or high levels of acid in the blood, which can cause seizures. See the OPSS FAQ to help you avoid hidden sources of caffeine.
