Ask the doctor

Q. I keep hearing that concussions can cause problems later in life. Should I be concerned about my grandkids playing sports, particularly football?

A. Sports teach kids many important life lessons, like the value of teamwork and hard work, and the importance of tenacity and resilience. The most popular sport in the United States is football. Yet evidence has emerged that repeated head injuries (common in football) may lead to a brain disease called chronic traumatic encephalopathy (CTE). This disease, which currently can be diagnosed only at an autopsy, causes difficulty thinking, severe mood swings, anger, violence — and death.

You may not be aware of physical changes that can make your old workout risky. Try these tips to ease into exercise.

Blame it on a job change, a chronic health issue, or simply a loss of motivation: whatever took you away from your regular exercise routine has led to a sedentary lifestyle. But don't assume you can jump back into the same exercise regimen you followed when you were younger. "Your body has aged, and things have changed," says Dr. Clare Safran-Norton, clinical supervisor of rehabilitation services at Harvard-affiliated Brigham and Women's Hospital.

What's different

Age-related physical changes aren't always obvious. "We lose muscle mass and strength as we get older, and the muscles become less flexible and less hydrated," says Dr. Safran-Norton. Arthritis weakens joints. And vision changes, neurological disease, joint pain, or problems inside the ear can throw off your balance.

This easy, stress-relieving exercise may help heal your heart.

If you have a heart attack or undergo stenting, improving your cardiovascular health should be a top priority. A great way to move toward that goal is to enroll in cardiac rehabilitation, a multiweek program of structured exercise paired with lifestyle and nutrition education.

Unfortunately, not all doctors refer their patients to such a program, which is recommended for a number of conditions, including most heart surgeries. Also, for a range of reasons, more than 60% of eligible people choose not to attend cardiac rehab. Sometimes travel and cost issues are barriers. But others worry that the exercise component of the program will be too difficult or tiring. For them, the ancient Chinese practice of tai chi may be a good alternative, according to a small study in the Oct. 11, 2017, Journal of the American Heart Association.

Even if you get enough exercise, you are still at risk for blood clots from too much sitting in front of the TV, according to research presented at the American Heart Association's Scientific Sessions in November 2017.

Prolonged TV viewing has already been associated with heart disease involving blocked arteries, but this is the first study in a Western population to look at blood clots in the veins of the legs, arms, pelvis, and lungs known as venous thromboembolism.

Your daily habits and lifestyle — what you eat and drink, whether you exercise, how stressed you are, and more — affect your mental health every bit as much as your physical health. A growing body of research indicates that regular exercise and a healthful diet can help protect your memory from aging-related decline.

Exercise

Physical fitness and mental fitness go together. People who exercise regularly tend to stay mentally sharp into their 70s, 80s, and beyond. Although the precise "dose" of exercise isn't known, research suggests that the exercise should be moderate to vigorous and regular. Examples of moderate exercise include brisk walking, stationary bicycling, water aerobics, and competitive table tennis. Vigorous activities include jogging, high-impact aerobic dancing, square dancing, and tennis.

You needn't spend a cent on fancy equipment to get a good core workout. Many core exercises rely on your body weight alone. But with the help of some simple equipment, you can diversify and ramp up your workouts.

The following items can help you put a new twist on your core exercises. Most of them can already be found around your house or are available at low cost from a sporting goods store.

You might be surprised to learn that what you eat affects your ability to move.

• The nutrients in the food you eat help your body build bone, power muscle, repair and replace tissues, and keep your brain active and your heart pumping.
• Your diet also influences your chances of developing chronic diseases such as type 2 diabetes, heart disease, and osteoporosis — all of which can compromise your well-being and hinder your ability to live an active and independent life.
• Eating the right foods is important, but so are how much you eat and how well you balance the calories you take in with those you burn off. Simply being overweight can make it more difficult to move easily in your day-to-day activities.

Keys to healthy eating

There is no shortage of diet books and healthy eating plans that claim to help you slim down and live a longer and healthier life. But healthy eating is surprisingly simple.

New Year’s resolutions aren’t just for grownups. Taking small steps toward a healthier, more connected life as a family can be fun and help lay the foundation for a lifetime of wellness.

If you believe that regular walking, jogging, or running provides enormous health benefits — as you know we do — there are two good reasons to consider a home treadmill, according to Dr. Aaron Baggish, associate director of the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital. First, exercise outdoors can be challenging and even dangerous in bad weather. Second, if the inconvenience and time required to go to a mall or indoor track keeps you from exercising, being able to do it at home makes it much easier. If you have any balance, heart, or lung problems, make sure your doctor clears you for a home treadmill.

Treadmill shopping

Dr. Baggish recommends avoiding nonmotorized treadmills and opting for a motorized model. "You can get a good starter model for about $1,000, but it's easy to exceed that if you want all the bells and whistles," Dr. Baggish says. Before you make the investment, do a little homework first.
