The good
news: It's possible to avoid potentially devastating falls.
Chris Kissell • August 17, 2020
As we age, our sense of
balance sometimes can betray us. The best way to avoid potentially devastating
falls is to prioritize staying balanced and to avoid tasks that steal our focus
from where it needs to be.
In fact, “dual-tasking” —
standing or walking while also performing a separate mental or physical task —
is the No. 1 source of falls for older adults, according to Brad Manor, an
associate scientist at the Hinda and Arthur Marcus Institute for Aging Research
and an assistant professor of medicine at Harvard Medical School.
Writing in the Harvard Health
Blog, Manor says older adults are much more vulnerable to falls if
they are moving when they try to perform a separate cognitive or motor task.
Examples might include
reading while walking, or talking and carrying a cup of coffee as you stroll.
Manor says simply
standing upright or walking down a well-lit hallway are surprisingly complex
physical tasks. Such activities involve continuously stabilizing our body’s
center of mass (which is just behind the sternum, or breastbone) over the
relatively small base of support that we create by how we position our feet on
the ground.
Manor writes:
“This control requires
quick reflexes, as well as strong muscles of the trunk, hips, legs, ankles, and
toes. However, to avoid falling we also need to pay attention to our body and
environment, predict and perceive unsafe movements of our body, and adjust
accordingly.”
As we grow older, simple
tasks such as standing and walking require greater levels of cognitive effort
as our senses and muscle strength begin to fade. As we spend more cognitive
effort on those tasks, it steals away resources from controlling our body’s center
of mass over our feet. Falls are often the result.
How to prevent falls
To prevent falling, Manor
suggests increasing awareness of your surroundings. Minimize distractions when
in a crowded room, walking on uneven sidewalks, or hurrying to get somewhere,
he says. Also, minimize or avoid talking while moving.
Keeping your mind sharp
can help. Manor writes that older adults with cognitive impairment are more
than twice as likely to fall as their peers who do not have such cognitive
issues. For help with that, check out “5 Secrets to
Keeping Your Brain Sharp as You Age.”
Engaging in mind-body
exercises such as tai chi, yoga or dance can help. These activities all help to
improve your balance.
Finally, Manor emphasizes
that falls are rarely the result of one factor. Poor muscle strength, fatigue
and failing vision can all contribute to falls. So, the best way to prevent
falls is to combine multiple preventive measures.
