No one wants to experience foodborne illness. However, there are safety tips and techniques that will help prevent such incidents. The Food and Drug Administration has developed Food Safety Tips for Healthy Holidays, which includes other helpful links about food safety.
Before 2013 comes to a close, the Navy will begin distributing Flame Resistant Variant (FRV) coveralls to all Sailors assigned to surface ships and aircraft carriers. Previously, only Sailors working in engineering departments, on flight decks, and in other high-risk areas were issued flame-resistant clothing. However, a recent review found that the highest risk of severe injury from flames was from major fires or explosions, which puts any Sailor at risk. Tests revealed that the Navy Working Uniforms (NWU) type I, made of a polyester cotton blend, are susceptible to melting in a fire, which could cause even greater injury to the wearer. The new FRV coveralls are 100% cotton with a fire-resistant coating, which is self-extinguishing. The Navy plans to improve and standardize all coveralls over the next couple years by combining the protective effects of flame resistance, arc-flash protection, and low-lint specifications into one safe and effective uniform.
HPRC’s series on staying happy over the holidays started last week (read the first BLUF here). This week, try experimenting with your expectations in order to sail through the holidays with a smile.
If you have visions of the holidays being a certain way—with lots of fun, togetherness, love, joy, and no discord—you may feel disappointed when the reality turns out to be something else. It’s natural to feel this way, but take stock of how your expectations perhaps contributed to your disappointment. Try experimenting with different ways of looking at things. For example, think about what’s behind your holiday expectations. Is it really a happier holiday when you spend more money? Can the entire holidays be filled with fun? Can you get along with everyone all the time? Are your expectations realistic?
Afterdeployment.org describes how to foster realistic thinking and have a clearer lens to the world by focusing on what is probable instead of wasting time thinking about things that are unlikely. In other words, focus on what you can control, not what you can’t. This can be particularly helpful for your relationships.
The holidays are supposed to be a time of joy, but for many the expectations around the season leave them feeling depressed, lacking in motivation, feeling family friction more acutely, and on top of all of that, vulnerable to overeating. Now’s the time to shift your thinking to stay happy this holiday season. Check back every week as we present tips on how you can do this for yourself.
Tip #1: Shift your thinking to decrease stress
Realistically, it’s unlikely you can make holiday stress just go away, but you can change your response to that stress. Noticing your thoughts and emotional reactions can empower you to experience different, less-charged reactions, resulting in more positive thoughts and actions. Learn about the common thinking traps that you can get stuck in and how to reframe them. Noticing and then shifting your thinking can have a big impact on what you feel—try it out and see for yourself.

Being able to be close and sexual are key aspects of intimate relationships. Warfighters struggling with PTSD, TBI, or other combat injuries may be surprised to find that injuries can impact their ability to have sex, derive pleasure from sex, or be intimate by connecting emotionally with their partner. Or conversely there might be too much emphasis on sex (engaging in or talking about it inappropriately).
To learn more, check out these two fact sheets from the Uniformed Services University: “Reintegration and Intimacy: The Impact of PTSD and Other Invisible Injuries“ and “Physical Injury and Intimacy: Managing Relationship Challenges and Changes.” Both include suggestions for how to improve intimacy.
You’ve been training, and now you’re in pain. It could be you’re having a painful introduction to one of your tendons. Strong tendons connect your muscles to the bones in your body and help you move by pulling on the bones when your muscles contract. Damage to tendons can occur from repetitive activities (including running and firing your weapon repeatedly over an extended period of time) or from sudden movements that put too much stress on a tendon. If you can’t avoid these activities, then pay attention to the warning signs that a tendon could be reaching its breaking point: pain, especially when moving the affected area; swelling over the area of pain; and, possibly, loss of motion in the joint.
The best way to avoid having to get treatment for tendonitis is to prevent it from happening in the first place! Follow these tips:
- Overall health: Maintain a healthy diet and weight, and check out HPRC’s Nutrition domain.
- Posture and body mechanics: Pay attention to your posture and make sure that you use correct body mechanics, especially when lifting and moving heavy objects.
- Maintain adequate muscle strength so your body can react to stresses you place on it.
- Maintain adequate flexibility.
- Consider proper workout gear, especially footwear; check out this HPRC article for more information.
- Activity modification: Rest the affected area. This could mean taking some time off from activities that cause pain and further damage. For example, if you’re a runner with Achilles tendonitis, try biking instead until the tendon has healed enough.
- Ice: Cold can help to decrease pain and swelling.
- Physical therapy: Gentle stretching and strengthening exercises, as well as massage, might help but should be done under the supervision of a healthcare provider.
- Anti-inflammatory medications: Ask your physician about medications that can help your condition.
- Bracing or casting might be needed in severe cases.
You should see your doctor right away if you experience fever, redness, and warmth in the affected area, or multiple sites of pain. For more information on injury prevention, check out HPRC’s “Preventing common injuries,” which covers six specific areas of injury: wrist and hand, knee, ankle, rotator cuff, back, and IT band.
Vitamin D is actually a hormone that your body produces when your skin is exposed to sunlight, earning it the nickname “sunshine vitamin.” It plays key roles in reducing your risk of many health conditions, including depression, cancer, heart disease, osteoporosis, and others. Spending 10 to 15 minutes outside on a sunny day with your arms and legs uncovered can provide nearly all the vitamin D most people need—challenging when you’re wearing a long-sleeved uniform or working inside all day—but you can also get some vitamin D in your diet from fatty fish (such as salmon), mushrooms, and many fortified foods.
The Recommended Dietary Allowance for most individuals is 600 IUs. People who have a vitamin D deficiency or certain medical conditions might require supplemental vitamin D but only under the supervision of their healthcare provider. That’s because excess vitamin D can be stored in your body, putting you at risk for toxicity. Over time, too much vitamin D can lead to irregular heart rhythms, kidney damage, and other serious health problems. If you take large doses of supplemental vitamin D and eat foods that are fortified with it, you could easily obtain more than recommended amounts.
Despite the risk for toxicity, nearly one-fourth of people living in the U.S. have low vitamin D levels, so all adults and children should have their vitamin D status checked by their healthcare provider. For more information about vitamin D, read this fact sheet from the Office of Dietary Supplements.

There are many components that contribute to a Marine's optimal readiness, including physical fitness, diet and nutrition, injury prevention, and fatigue management. A balanced and effective approach for optimum performance and combat conditioning should address all four aspects. That’s where HITT comes in.
HITT is a comprehensive strength and conditioning program that takes into consideration the physical demands of operational activities to help Marines optimize their combat readiness. The HITT program focuses on the key components of superior speed, power, strength endurance, combat readiness, and injury prevention.
The four major components of the HITT program include:
- Injury Prevention (including active dynamic warm-up)
- Strength and Power
- Speed, Agility, and Endurance
- Flexibility and Core Stability
The HITT workout program can be customized as a training tool for a unit or an individual. It can also supplement your current training routine. The workouts are divided into three different modules to address each of the four components listed above.
- Athlete HITT develops basic strength and speed using barbells, kettle bells, dumbbells, speed harnesses, resistance trainers, and sleds.
- Combat HITT develops functional strength and endurance using suspension trainers, ammo cans, partner drills, and endurance training.
- Warrior HITT develops explosive power and agility using Olympic lifts, plyometrics (jumping exercises), battle ropes, cones, hurdles, and ladders.
Exercise videos provide instruction and demonstrations on how to do the exercises and movement properly. The program also uses periodization to promote long-term training improvements while avoiding over-training. Lastly, the program is categorized into specific phases, each with its own objectives and set of training parameters:
- Pre-Deployment Phase (Warrior, Combat, Athlete). The main goal is to build overall strength and performance, similar to “off-season training” in a traditional sport setting.
- Deployment Phase (Combat). The objective is to maintain overall fitness levels and reduce the risk of injuries while deployed. This is the Marine’s “in-season training”.
- Post-Deployment Phase (Athlete). The emphasis is reintegration/strengthening. If a Marine were to sustain injury or lose a significant level of performance, this phase would help get him/her return to full training status.
HITT is endorsed by the National Strength and Conditioning Associations (NSCA) Tactical Strength and Conditioning (TSAC) Department. By implementing the latest cutting-edge training methods and sound science, the HITT program builds fitness for today's tactical athlete – the United States Marine.
