Why Seniors Need More
Natural Light
(ARA) – As we age, the lenses
of our eyes thicken and our pupils shrink. This
causes eyes to adapt more slowly to changing light
conditions and increases the need for light.
According to the Center of Design For An Aging
Society in Portland, Ore., older people need three
to five times more light than younger people for
vision and to maintain health.
Many seniors don’t get outside enough, another
reason to bring more natural light in. Studies show
that Seasonal Affective Disorder (SAD), evidenced by
emotional depression, a drop in physical energy,
increased appetite, and need for more sleep, is
directly linked to a lack of sufficient daylight.
Some researchers conclude that light therapy may
help to alleviate SAD symptoms faster than
antidepressant drugs. In a review of clinical trials
of light therapy, Dr. Daniel Kripke at the
University of California, San Diego, reported that
light therapy benefits not only SAD patients but
also people suffering from other forms of
depression.
Sunlight can enter our dwellings and be balanced
through the use of windows, doors and skylights.
According to Joe Patrick, senior product manager
with VELUX America, studies conducted in Denmark
show skylights admit 30 percent more light than
vertical windows in dormers, and provide the drama
of a sky view that can’t be achieved with vertical
windows. And balanced natural light from multiple
sources can help to reduce glare, a particularly
disorienting nuisance for people of all ages with
glaucoma or cataracts.
“Skylights also offer much more privacy than
vertical windows without taking up valuable wall
space that can be used for decorating or storage,”
Patrick says, “a real benefit as seniors downsize
living spaces.”
He points out that venting skylights can contribute
to a healthier indoor environment by utilizing their
natural chimney effect to exhaust rising, stale air
containing volatile organic compounds (VOCs), and
other indoor pollutants to which older people are
particularly sensitive.
“From an economic standpoint,” Patrick says, “Energy
Star qualified venting skylights admit natural light
from above and reduce energy costs while
transforming living areas into bright, safer spaces.
And they provide a dose of the medicine that
daylight and fresh air offer.”
“It’s also a way to stretch fixed-income dollars,”
Patrick says, “with a one-time purchase that pays
benefits over time by reducing the need for
artificial lighting and cutting energy costs.”
In areas where traditional skylights aren’t needed
or won’t fit, cost-effective, passive light to
further reduce energy cost is available with a
tubular model like the VELUX Sun Tunnel skylight.
These less expensive units can be installed in two
to three hours and are particularly useful in
hallways, closets, interior baths and other smaller,
confined areas needing more natural light.
