Do you feel slightly more
depressed during the Winter? Have you tried light therapy at home?
It may sound silly, but we tried here. It really works, and is so inexpensive! Check out what experts and newspapers are
saying:
"Patients
generally sit in front of the light box, which can be as small as 9 by 11
inches and 5 inches deep, with the bright light emanating from the square
surface, in the morning. “With the natural dawn being later in winter, the body
rhythms drift late,” Dr. Lewy said. “If you can fix the drift, you can fix the
depression. Light therapy may even help
with major nonseasonal depression, experts say, and withsleep disorders. And because it has few side
effects, researchers are studying whether light therapy can help with
depression during pregnancy and be used to treat elderly
people with dementia. It is also being investigated for
the treatment of bulimia nervosa, severepremenstrual syndrome and even attention deficit hyperactivity disorder and bipolar disorder. The American Psychiatric
Association considers bright-light therapy an effective low-risk treatment for
both S.A.D. and nonseasonal major depressive disorder. No one knows exactly how
light treatment works, but most experts seem to agree that the body has a
master biological clock that responds to or is “set” by natural light
fluctuations. “Light does more than just enable us to see,” said Dr. Norman
Rosenthal, author of the landmark book “Winter Blues,” who was among the first
to identify and describe S.A.D. Light also has an effect on hormones, the body’s
chemical messengers, affecting the brain’s hypothalamus, which is involved in
regulating mood, energy and appetite. “The hormone melatonin, which
is secreted at night, can be suppressed by light,” Dr. Rosenthal said. “Studies
have also shown that light influences serotonin and epinephrinepathways in the brain, the same
neurotransmitter systems known to be affected in people with general
depression.” But while part of the appeal of light therapy is that it can be
self-prescribed, using a light box is not as simple as it may appear. "
Experts recommend
consulting with a knowledgeable health care provider before starting treatment
to rule out other medical conditions and to help with monitoring and adjusting
bright-light exposure.
