A pain in the…shin?

Shin splits can sideline you from your regular exercise routine, but proper treatment and rest can get you back in action sooner rather than later.

If you exercise regularly—or plan to start an exercise program—chances are you’ll experience shin splits at least once. That sharp, achy, sore, and/or throbbing feeling that runs down the front of your shin, also known as “tibial stress syndrome,” is a common condition among athletes, especially runners. The pain of shin splits can come from any number of underlying causes, such as overuse injuries, “flat feet,” or a more serious injury—stress fractures—usually from excessive and/or repetitive force on your legs. Usually shin splits will heal on their own with rest and basic self-care treatments, but it’s important to recognize the symptoms early on and to give yourself time to fully heal before easing back into your usual workout. See a doctor if the pain does not seem to improve with rest, if your shin is hot and inflamed, or if the swelling gets worse. To prevent shin splits, make sure that you wear the appropriate shoes for your type of foot, warm up before working out, vary the types of surfaces you run on, and address symptoms of pain early.

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.

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.

Small changes can pay off in a big way

HPRC Fitness Arena: Family & Relationships
Resolutions don't have to daunting—making small, not big, changes that fit easily into your lifestyle are good options for family health and weight loss over time.

It’s the New Year! If you’re already despairing about resolutions, keep in mind that making small changes in behavior that fit easily into your lifestyle are good options for family health and weight loss over time. For one month, try choosing three small habits to focus on changing that you can apply to any situation, whether you’re at home, overseas, or travelling. Try setting up email or calendar reminders if that helps you, or put up tangible reminders such as sticky notes around your house. To get you started, here are some ideas:

  • Keep unhealthy foods such as potato chips, cookies, etc. out of sight so they are less tempting.
  • Put down your fork and knife between bites.
  • Portion out “snackable” foods that come in large bags/containers into smaller one-serving containers, so you don’t keep dipping in.
  • Choose water over soda.
  • Keep fresh fruit on hand to replace fatty, high-calorie snacks.

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, 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. For more information and ideas, check out HPRC’s article on sleep and visit HPRC’s Sleep Optimization resources.

Start your children’s good sleep habits early

Sleep is an essential part of post-exercise recovery, and good sleep habits begin in childhood. A recent Canadian report on bringing up children as athletes provides valuable input for children at various ages.

Do you know how much sleep you and your loved ones are getting—and supposed to be getting?  Keep in mind the recommendations differ by age group. According to a report from Canadian Sport for Life on optimal sleep for athletic performance at all life stages:

  • Children under the age of six need 13–16 hours of sleep daily, including longer nighttime sleep and fewer daytime naps as they get older.
  • As girls reach the ages of 6–8 and boys reach 6–9, their sleep needs drop to 10–11 hours of sleep a night.
  • Girls 8–11 and boys 9–12 need 9 ½ to 10 hours of sleep a night.
  • Girls 11–15 and boys 12–16 need around nine hours of sleep a night.
  • In addition to their nightly sleep, girls 6-15 and boys 6-16 need a 30-minute-plus nap between 2–4 pm every day.

For young children, meals—particularly breakfast—are an important part of establishing a reliable sleep routine, and as children age they should start developing a 15–30 minute routine before bedtime to get ready physically for sleep. This is also a great opportunity for some quality time between parents and children that you can all look forward to each night.

To make this goal easier, be sure your kids avoid computers and TVs (anything with electronic stimulation) for one to two hours before bedtime. Allow an hour to unwind before bed—try soothing music, reading, and dim lighting.

As children become teenagers, make sure they don’t start incurring a sleep debt by sleeping less than needed. Encourage them to keep regular sleep hours, get early morning light exposure, and carefully gauge their caffeine consumption close to bedtime.

The report mentioned above suggests using a sleep log (and provides a sample log) to get an idea of your and your child’s sleep patterns. Remember that the warrior athletes of tomorrow need to develop good sleep habits today!

Had enough to drink?

HPRC Fitness Arena: Mind Tactics, Total Force Fitness
Drinking too much alcohol affects your health, your job, and your family. But how much is too much? For optimum Warfighter performance, you need to know.

Have you ever wondered what’s considered “too much to drink? According to the American Psychological Association, a “relatively harmless” or “moderate” amount is no more than two drinks a day for men and one for women and older people. One drink is defined as 12 ounces of beer, five ounces of wine, or 1.5 ounces of spirits.

However, anyone who continually drinks alcoholic beverages despite repeated negative consequences is guilty of “alcohol abuse.” Those who can’t stop drinking once they start or who have to drink more to get the same effect—a phenomenon called “developing tolerance”—are alcohol dependent. This pattern of drinking, known as alcoholism, damages a person’s health, relationships, and ability to work. However, there is a category known as the “functional alcoholic.” Such people remain highly functional, with their jobs, homes, and families intact, making the problem difficult to identify.

To see how your own drinking habits stack up, visit for an assessment of whether you or someone you care about has a problem with alcohol. They offer resources and information on how to address alcohol-related issues. HPRC also provides more information on alcohol use and abuse, including service-specific programs.
