New guidelines help cancer survivors exercise and eat better

Daniel Pendick, Executive Editor, Harvard Men's Health Watch

Surviving cancer was once a challenging achievement. Today, more than 12 million Americans are cancer survivors, and many live long after their diagnoses. New guidelines from the American Cancer Society (ACS) offer them science-based advice for eating better and staying active—two keys to healthy living for cancer survivors and everyone else. The report, called Nutrition and Physical Activity Guidelines for Cancer Survivors, is available for free from the ACS website. The guidelines provide specific advice for survivors of a variety of major cancers: prostate, colorectal, lung, breast, ovarian, endometrial, upper GI, head and neck, and hematologic. They urge cancer survivors to maintain a healthy weight, avoid inactivity and return to normal daily activities as soon as possible following diagnosis, eventually aim to exercise at least 150 minutes per week, and follow an eating pattern that is rich in vegetables, fruits, and whole grains.

Join in on National Walking Day

P.J. Skerrett, Senior editor, Harvard Health
People walking

Today is National Walking Day. Join the celebration by taking a walk. This particular health observance is sponsored by the American Heart Association (AHA). Although it applies to everyone, it’s really aimed at adults who spend most of the workday sitting. The heart association hopes to get workers out of the office, store, or factory for a 30-minute walk. And not just today, but every day. If you don’t exercise, or do it only now and then, walking is an excellent way to get more physical activity. Just 30 minutes a day of brisk walking (or other moderate exercise), helps your heart, blood vessels, muscles, brain, and the rest of your body. If you don’t usually exercise, use National Walking Day as an invitation to get started. If you do exercise, use the day to invite a friend to get on the path to better health with a walk.

Exergames: a new step toward fitness?

Lloyd Resnick, Editor, Harvard Health
Video boxing

Active-play videogames, also known as exergames, are a high-tech approach to fitness that could help some people become more active and stay that way. As described in the March 2012 Harvard Heart Letter, exergames offer muscle-strengthening workouts, balance and stretching games, aerobic exercises and dancing, martial arts, and simulated recreational activities such as golf, skiing, and more. Current exergames deliver moderate workouts at best. Some fitness and senior centers now incorporate exergames into their facilities. For a home system, you’ll probably spend about $250 for the basics — console, accessories such as handheld controls or balance board, and software.

Virtual reality, exergames may improve mental and physical health

P.J. Skerrett, Senior editor, Harvard Health
Virtual-reality

Games are meant to be fun and exciting. Some involve the body, some the mind. Others do both. Researchers are tapping into this engagement to use games to heal an ailing mind or body. Researchers are testing virtual reality to help people with mental and physical problems ranging from post-traumatic stress disorder and stroke rehabilitation to smoking cessation and stuttering. Exergames may also help people become more physically active. Although they won’t help you lose weight or train for a marathon, many meet the American Heart Association’s criteria for “moderate-intensity daily activity,” meaning they could stand in for taking a walk.

Treating neck pain with a dose of exercise

Kay Cahill Allison, Editor, Special Health Reports
Neck-pain

For neck and shoulder pain, doctors once recommended rest, maybe the use of a neck brace, and waiting until the pain had ebbed away. Today there are recommending movement instead of rest. As described in Neck and Shoulder Pain, a newly updated Special Health Report from Harvard Health Publications, there is mounting scientific evidence for the role of stretching and muscle strengthening in treating people with neck and shoulder pain. After a whiplash injury, for example, people heal sooner and are less likely to develop chronic pain if they start gentle exercise as soon as possible. For those with long-term pain (called chronic pain) results from controlled studies show that exercise provides some relief. Exactly how much exercise to do, what types are best, and how often it should be done have yet to be completely hashed out.

Does fitness offset fatness?

At least for men, being more fit may have a bigger health payoff than losing weight, according to a new study of more than 14,000 well-off middle-aged men who are participating in the Aerobics Center Longitudinal Study. Researchers followed their health, weight, and exercise habits for 11 years. Compared with men whose fitness declined over the course of the study, those who maintained their fitness levels reduced their odds of dying from cardiovascular disease or any other cause by about 30%, even if they didn’t lose any excess weight. Those who improved their fitness levels saw a 40% reduction. For optimal health, being fit and maintaining a healthy weight are best. But if you are overweight and inactive, this study and others suggest that getting more activity is the best place to start to improve your health.

Whole-body vibration doesn’t slow bone loss

Howard LeWine, M.D., Chief Medical Editor
Internet Publishing, Harvard Health Publications

Good vibrations may work for dancing on the beach or for romance, but they don’t seem to do much to strengthen bones. Results of a clinical trial published in the Annals of Internal Medicine showed that older women who stood on a vibrating platform for 20 minutes a day experienced just as much bone loss over the course of the year-long trial as women who didn’t use the platform.

Want to make a healthy change? Start with the right goal

Annmarie Dadoly, Editor, Harvard Health Publications
changes

Replacing unhealthy behaviors with healthier ones usually isn’t easy, and many ambitious attempts often fall short. But you’re more likely to succeed if you start by choosing the right goal—the one you are most likely to accomplish—rather than the goal you think you should make. Breaking a goal into bite-sized pieces also helps. So does making your goal a SMART one (specific, measurable, achievable, realistic, and time-based).

Change: One man’s steady struggle to become healthier

P.J. Skerrett, Senior editor, Harvard Health

It isn’t easy to get rid of a harmful habit like drinking too much, or to make healthy changes like losing weight and exercising more. Media stories often sugar-coat changes like these, making them seem easier than they really are. In a moving essay in the American Journal of Health Promotion, Michael P. O’Donnell (the journal’s editor) describes his dad’s efforts to become healthier for his sake and the sake of his family. There was no monumental struggle, no epiphany—just a regular guy doing his best each day to become healthier for his sake and for his family. It’s a truly inspiring story.

Strengthening your core: Right and wrong ways to do lunges, squats, and planks

Annmarie Dadoly, Editor, Harvard Health Publications

Your body’s core—the girdle of muscles, bones, and joints that connects your upper and lower body—gives you stability and helps power the moves you make every day. Whether it’s bending to pick up a laundry basket, paddling a kayak, or reaching to pull a vase from the top shelf of a cabinet, a strong and flexible core makes the move more fluid, efficient, and robust. Strong, well-balanced core muscles can also improve your posture and help prevent back injuries. Exercise and fitness programs increasingly focus on the core. Lunges, squats, and planks (a move that looks a bit like a push-up and is often substituted for sit-ups) are key moves in most good core workouts. But it’s important to pay attention to proper form to protect you from injury and help you gain the most benefit from each exercise.
