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
Exercise helps memory in several ways. It reduces the
risk of developing several potentially memory-robbing conditions like high
blood pressure, diabetes, and stroke. Exercise is good for the lungs, and
people who have good lung function send more oxygen to their brains. There is
some evidence that exercise helps build new connections between brain cells and
improves communication between them. Finally,
exercise has been linked to increased production of neurotrophins, substances
that nourish brain cells and help protect them against damage from stroke and
other injuries.
Here are some ways to build physical activity
into your daily routine:
·
Walk instead of
driving when possible.
·
Set aside time each
day for exercise. For extra motivation, ask your spouse or a friend to join
you.
·
Use the stairs
instead of the elevator.
·
Plant a garden and
tend it.
·
Take an exercise
class or join a health club.
·
Swim regularly, if
you have access to a pool or beach.
·
Learn a sport that
requires modest physical exertion, such as tennis.
Go Mediterranean
Mediterranean-type
diets highlight whole grains, fruits and vegetables, and healthy fats from
fish, nuts, and healthy oils. This
eating style helps promote heart health and may also lessen the risk of memory
and thinking problems later in life. In a study that followed more than 2,000
people over four years, those who most closely followed a Mediterranean-type
diet had a lower risk of developing Alzheimer's disease. A later study
suggested that following a Mediterranean-type diet could slow the conversion of
mild cognitive impairment into full-blown dementia.
The types of fat that predominate in the diet
also seem to affect memory. As part of the national Women's Health Initiative,
482 women ages 60 and older were observed for three years. They reported on
their diets, and researchers tested their memory and thinking skills at the
beginning of the study and at the end. Those who ate more unsaturated fat
(which is abundant in vegetable oils and fatty fish) and less saturated fat
(from red meat and full-fat dairy foods) had significantly less decline in
memory than those who ate relatively little unsaturated fat.
Eating several servings of fruits and
vegetables can also protect memory. Foods from plants are chock full of
vitamins, minerals, and other nutrients that may protect against age-related
deterioration throughout the body.
