Aquaman to the rescue!

Filed under: Diving, Environment, Gear
Scientists hope to turn military divers into real life “Aquamen” with new technology designed to help them avoid some of the dangers associated with diving.

Pentagon scientists are hoping to build special gear designed to turn divers into veritable Aquamen (and Aquawomen). Although it’s still in the research phase, the new system would protect divers from the adverse effects of diving too deep or surfacing too fast. Sensors would read and adjust to a diver’s physical signs as well as help control levels of nitric oxide to prevent the decompression sickness known as “the bends.” When a diver ascends too quickly, bubbles form inside the body, which can block the blood vessels in the spinal cord and disrupt the nervous system. It can be very painful and can lead to joint pain, paralysis, and even sudden death if a diver is not careful.

The new diving gear will be a portable and versatile system that can potentially serve for use in other special operations as well as for civilian divers. This system will have to be designed for the most extreme combat dive profiles, which sometimes require a 35,000-meter free-fall from an aircraft, diving 200 feet below the surface for at least two hours, surfacing, and immediately diving again, followed by continued protection after being picked up in an unpressurized aircraft. This is one of DARPA’s most recent Small Business Innovation research proposals for 2013.

Meditation has a lasting effect on emotions

Need another reason to meditate? Integrating meditation into your daily routine may benefit how you process your emotions in the long term.

Researchers have long been interested in meditation and its potential benefits. A recent study found that regular meditation practice of 20 minutes a day has a lasting effect on how your brain processes emotions. This suggests that meditation could potentially help your brain handle stress, anxiety, and depression, and possibly other feelings. For those individuals dealing with relocation, deployment after-effects, chronic stress overload, recent family changes, or new training assignments, having a strategy to improve your resilience and help process the expected extra doses of emotions can be helpful.

Don’t waste time hoping for a better situation; make the best of wherever you find yourself and plan to be successful while you’re there using the resources you have. Whether you have performance goals of enhancing your physical fitness, becoming stronger mentally, bolstering your spirit, eating better, or enhancing your relationships, make sure that your “tools” are in good condition and ready to be used at any time. This can be particularly helpful if you (or your loved one) are on TDY or deployment because you can carry your performance-enhancement tools within you and employ them when needed.

For ways to sharpen your tools for Total Fitness (resilience and performance enhancement), check out the One Shot One Kill performance enhancement program to be prepared no matter where you are. Or if you have specific performance areas you want to strengthen, check out the other domains of HPRC’s website: Physical Fitness, Environment, Nutrition, Dietary Supplements, Family & Relationships, and Mind Tactics.

Solid fats vs. oils

HPRC Fitness Arena: Nutrition, Total Force Fitness
Solid fats vs. oils can make a difference in the overall makeup of a healthy diet, and choosing unsaturated oils can help lower blood cholesterol.

Solid fats are solid at room temperature, come mainly from animal products, and are high in saturated or trans fats. Examples are butter, milk fat, cream, stick margarine, shortening, and beef, chicken, and pork fat. Some saturated fats increase blood cholesterol levels in the body. Oils are liquid at room temperature, and come from many different plants, and are good sources of heart healthy unsaturated fats. Examples are olive oil, canola oil, safflower oil, corn oil, soybean oil, and peanut oil. Coconut oil, palm oil, and palm kernel oil are high in saturated fats and are considered solid fats. When using fats, replacing solid fats with unsaturated oils will provide essential nutrients to the diet and help lower blood cholesterol levels.

Sleep needs for adults

Optimum performance requires optimum sleep as part of post-exercise recovery. A recent report shows that athletes—including warrior athletes—need extra.

According to a recent report about post-exercise recovery and regeneration for athletes, men over 19 and women over 18 needs 8-10 hours of sleep a night (plus a 30-minute afternoon nap, as needed) for optimal athletic performance.

Continuing good sleep habits established earlier in adolescence such as regular meals, early morning light exposure, and a nightly sleep routine remain important. However, it’s also important to monitor the effects of stress and changes in sleep due to training/military operations.

Even if you’re not an athlete, the recommendations above still apply, except that your total sleep needs are seven to nine hours a night to keep you at your best.

Some additional tips for sleep:

  • Regular exercise during the day can help you sleep better at night.
  • If you have a question about whether to exercise more or sleep, choose sleep!
  • During the night, if you wake up and after 20 minutes haven’t gone back to sleep, get out of bed, do something relaxing, and then get back in bed. You’ll probably fall right asleep.

Also, for a better understanding of your current sleep habits, afterdeployment.org has an online “sleep assessment” that you can take. For more information on how to optimize your sleep, visit the HPRC’s Sleep Optimization section.

Accident prone? Get some sleep!

When it comes to reducing your risk for accidents and enhancing your performance, sleep is one tool that has comprehensive benefits!

Did you know that missing a night of sleep can produce performance results similar to those of being legally drunk? Even losing just a few hours of sleep can result in accidents and poor physical and mental performance. Sleepiness can inhibit balance, coordination, concentration, and response time—creating “the perfect storm” for accidents.

Make sure your sleep is optimal by turning off your electronics and other distractions well before bedtime, exercising during the day, avoiding caffeine late in the day, and sticking to a consistent sleep schedule. If you are in a situation where sleep is hard to come by, try to squeeze in naps when possible.

Caffeine in supplements – how much?

Some of the most popular dietary supplements sold on military bases may give inaccurate—or no—information about caffeine content on their labels.

A Military Times article reports on a recent study of more than 30 of the most popular dietary supplements (in capsule form) sold on military bases analyzed to determine their caffeine content. Of the 20 supplements that listed caffeine as an ingredient on their labels, six did not specify the amount. These same six contained high amounts of caffeine (210-310 mg per serving)—three or more times the amount permitted by law in soft drinks. Five others revealed significantly different amounts—some more, some less—than the quantity stated on the product label.

Consuming too much caffeine can result in health issues. And if you don’t know how much is in the supplement you’re taking, it could be easy to overdo it if you also drink coffee or energy drinks. Visit the Operation Supplement Safety (OPSS) FAQ on caffeine for additional information.

Reduce work-related aches and pains

Filed under: Exercise, Stress, Yoga
Not only can yoga reduce stress, it can also help to reduce the risk of those annoying aches and pains.

Many jobs involve duties that can cause minor musculoskeletal tension that builds over time until you find yourself experiencing pain. Sitting or standing for long periods of time, lifting or carrying heavy objects, and other common mission-related actions of active-duty personnel wear on the body, leading to increased risk for injury. Yoga can help to reduce this risk by improving posture, increasing energy, and stretching overused or tense muscles. If you don’t have time for yoga between work, your normal exercise routine, or family obligations, suggest sharing a quick yoga session with buddies in your unit during a break to reduce your risk for injury and help get through the afternoon. There are different styles of yoga for all skill levels.
