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.
Bad things happen. Unfortunately, you can count on experiencing different traumas, deaths, illnesses, and injuries. As a Warfighter (or military family), you can probably expect to face these kinds of situations more often than other people. That doesn’t make these experiences any more pleasant, and often it doesn’t make them any less surprising. After a major trauma, illness, or life-changing event, it is often necessary to adapt and create a “new normal.”
Studies of “post-traumatic growth” have found that trauma survivors can grow mentally, emotionally, and spiritually after horrendous experiences such as cancer, terrorism, sexual assault, plane crashes, and even combat. It’s common to react with an emotional roller coaster of denial, anger, bargaining, depression, and acceptance. Your natural instinct might be to run from these feelings. However, post-traumatic growth can be accomplished better by taking steps to approach them. The people who support you (including but not limited to therapists and family members) can do the following:
- Listen empathically, accepting and encouraging full expression of feelings.
- Avoid clichés and easy answers. Hearing “there will be brighter days” is not helpful.
- Be patient. Changing perspective won’t happen overnight.
- Offer a helpful relationship, recognizing there is no “magic technique” or “quick fix.”
You can also be an active agent in your own healing. One technique that can be useful to you is to tell and retell versions of your story in order to become more immune to the hard parts and to reach a point where you can find new meaning in it. People of any age, including Warfighters, can benefit from actively embracing a “new normal” through taking advantage of your relationships and developing a new twist on their story, even when this initially might seem far-fetched.
A key step toward achieving and maintaining a healthy weight is learning to accurately gauge how much you’re eating. In other words, how big are your portions? The most accurate way to gauge your portions is to measure or weigh your food, but who wants to take measuring cups and a scale to the chow hall? A more practical way to gauge your portion sizes is to “eyeball” them—that is, to visually compare your food portions to a familiar frame of reference. Of course, you might have larger or smaller hands, but generally speaking your hand size equates to your body size and, as a result, your portion needs. This infographic from HPRC uses your hand as your guide—a “handy” way to keep portion sizes in check, which can mean a leaner, healthier, better-performing you.
Athletes have rituals they engage in to ensure their best performance. Warfighters have rituals around paroling, shooting, and other mission-specific tasks to create the right mindset for the situation. Families can benefit from rituals too.
Consider the types of rituals your family typically engages in. There are probably more than you think. Celebrating holidays, personal traditions such as pancakes on Saturday mornings or memorializing the death of a loved one, and simple everyday acts such as bedtime stories or morning tea are all rituals.
When a couple comes together and starts a family, each person brings along his/her own rituals. Consider it an opportunity to build something new together—a blending of histories. For example, let’s say you grew up celebrating Christmas with your family, but your partner’s family celebrated Hanukah. As a couple you can take the rituals that are meaningful to each of you personally and celebrate all of them to create a new combined holiday tradition for your own family.
Rituals certainly can help your own performance, but they also help deepen bonds and create a distinct family identity that can be supportive in both happy and stressful times.
