Healthy Aging

Feeling young at heart may help you live longer

Feeling young may be one way to keep getting older. In a new study, a pair of researchers from University College London found that older people who felt three or more years younger than their actual age were more likely to be alive eight years later than those who felt more than one year older than their actual age. Does a youthful feeling keep people alive? Possibly: feeling younger may lead to better health habits, like exercising and eating healthfully. Feeling younger may also inspire a sense of resilience that keeps people young.

High blood pressure in midlife linked to later decline in memory, thinking skills

A new report in JAMA Neurology offers yet another reminder why keeping your blood pressure in the healthy range for as long as you can is a good life strategy. Researchers with the long-term Atherosclerosis Risk in Communities (ARIC) Neurocognitive Study found that memory and thinking skills declined significantly more over the course of a 20-year study in middle-aged people with high blood pressure than it did in those with healthy blood pressure. Interestingly, those who had normal blood pressure in midlife but who developed high blood pressure in their late 60s, 70s, and 80s didn’t have similar declines as those who developed high blood pressure earlier. The main take-home lesson from this study? The longer you live with normal blood pressure, the less likely you are to have memory and reasoning problems when you’re older.

Caffeine and a healthy diet may boost memory, thinking skills; alcohol’s effect uncertain

A study published in this month’s Journal of Nutrition suggests that drinking caffeinated beverages, having the occasional alcoholic drink, and eating a healthy diet may help preserve memory and thinking skills long into old age. In particular, foods that are part of the Mediterranean diet—fruits, vegetables, nuts, fish, olive oil, and whole grains—show promise for preserving memory and preventing Alzheimer’s and other forms of dementia.

Walking, other exercise helps seniors stay mobile, independent

If you want to stay healthy and mobile well into old age, start walking today—even if you’ve already edged into “old age.” That’s the conclusion of a report from the Lifestyle Interventions and Independence for Elders (LIFE) trial, published online yesterday in the Journal of the American Medical Association. Frail, inactive older people between the ages of 70 and 89 who started exercising were less likely to have become disabled over the course of a 30-month trial than a similar group who took part in workshops on healthy aging. Some older people they have passed the age at which starting an exercise program will do them any good. These new findings reinforce what other studies have shown: You’re never too old to exercise.

Regular exercise changes the brain to improve memory, thinking skills

There are plenty of good reasons to be physically active. Big ones include reducing the odds of developing heart disease, stroke, and diabetes. Maybe you want to lose weight, lower your blood pressure, prevent depression, or just look better. Here’s another one, which especially applies to anyone experiencing the brain fog that comes with age: exercise changes the brain in ways that protect memory and thinking skills. In a study done at the University of British Columbia, researchers found that regular aerobic exercise, the kind that gets your heart and your sweat glands pumping, appears to boost the size of the hippocampus, the brain area involved in verbal memory and learning.

After hip fracture, exercise at home boosts day-to-day function

Even after intensive rehabilitation therapy, many people who break a hip still can’t do things they used to do with ease, like dressing, rising from a chair, or climbing stairs, after . A report in this week’s Journal of the American Medical Association shows that simple exercises done at home can make a big difference in recovering from a broken hip. A set of “functional exercises” that mimic the kinds of things people normally do in their daily lives improved function and mobility among people who had broken a hip. It’s important :just do it.” At-home rehab is of no use if you don’t stick with it. These kinds of exercises can also help ward off post-fracture complications like blood clots, pneumonia, wound infections, and more. Extended bed rest after a major injury or surgery can feed a downward spiral of physical deconditioning and additional health problems.

Too much sitting linked to an early death

Many Americans spend most of each workday sitting in a chair, their fingers the only part of their bodies moving with any intensity. The ease of this modern workday could come at the expense of longevity. A new study of older women in the American Journal of Preventive Medicine finds that sitting for long stretches of time increases the odds of an untimely death. And here’s the kicker: Regular exercise doesn’t do much to diminish the risk of sitting all day. When you sit, you expend fewer calories than you would while standing, and you demand little effort from your muscles. This can help set the stage for diabetes and heart disease. One way to avoid prolonged sitting during the workday is to switch to a standing desk, or one that can adjust to sitting and standing positions. An easier, no-cost solution is to set your smartphone timer to go off every 30 to 60 minutes during the day, and move around when the alarm rings.

Mediterranean-style diet linked to healthier arteries throughout the body

A landmark clinical trial done in Spain, known by the acronym PREDIMED, continues to support the health benefits of following a Mediterranean-style eating pattern. Last year, PREDIMED researchers reported that Mediterranean-style eating—rich in fruits, vegetables, and healthy plant oils—prevents heart attacks, strokes, and death from heart disease. This week in The Journal of the American Medical Association, they report that a healthy Mediterranean-style diet can also help prevent peripheral artery disease (PAD), a form of “hardening of the arteries.” It’s an important finding, since as many as 12 million Americans have PAD. It can cause leg pain when walking that goes away with rest (called intermittent claudication); a weakening of the aorta, the main pipeline that delivers blood to the body; pain after eating; erectile dysfunction; and other problems.

94-year-old Master track star an inspiration to all

A recent article in Parade magazine caught my eye because it has lessons for us all. The article was about Olga Kotelko, a 94-year-old woman, who is a competitive runner and track star. Her age alone is impressive. The fact that she didn’t enter her first Master’s competition until she was 77—an age when many people are hanging up their sneakers—is amazing. The article offers six lessons that anyone can learn from Ms. Kotelko’s daily life. She can be an inspiration for anyone, at any age, who wants to start exercising or to exercise more. You are never too old or too frail to start exercising. Start out with a safe, easy program. Gradually add more and harder exercise. Who knows where you might end—possibly in an event challenging the likes of Olga Kotelko.

Two-thirds of seniors need help doing one or more daily activities

A longer lifespan can be a double-edged sword. You live for more years, but the later years may not necessarily be what you had in mind. We’ve known for some time that about 25% of older Americans can’t perform some activities of daily living without help. But we don’t know much about the other 75%. A new study suggests that two-thirds of Americans over age 65 need help doing everyday activities such as eating, bathing, and getting in and out of bed or a chair. Things you can do to help ward off becoming frail or disabled include staying active, managing weight and eating a healthy diet, preventing falls, making connections with others, and seeing your doctor(s) regularly.
