Don't
be S.A.D. in the winter
SAD stands
for Seasonal Affective Disorder. Many people find that they
sleep and eat slightly more in the winter, and dislike the
dark mornings. For some however the symptoms are enough to
disrupt their lives and cause considerable distress. These
people have SAD.
The latest
(1998) research indicates that in Britain about half a million
people suffer from clinical S.A.D. with around five million
having milder symptoms in varying degrees.
SAD stems
from the lack of bright light in winter. Researchers have
proved that bright light makes a difference to brain chemistry.
The production of Melatonin, a substance that makes us drowsy,
is suppressed by bright light entering the eyes. The lack
of bright light on dull days inhibits this natural waking
process. Exposure to bright light also appears to increase
the production of a substance called Serotonin, a neurotransmitter
that carries signals between the nerves in the brain. Lack
of Serotonin is known to be a cause of depression.
In some
extreme cases, the prospect of the long winter haul is enough
to make them so depressed as to feel suicidal. Others may
just feel quite miserable, with symptoms such as problems
with sleep patterns, overeating, depression, loss of libido,
irritability, lethargy, joint pain and stomach problems, and
even behavioural problems in young children may be attributed
to SAD.
Help is
at hand. Using lightbox therapy, or other similar devices
that are able to project the correct level of light, may help
to reduce the symptoms. In some cases just half an hour a
day is sufficient to help reduce tiredness, depression and
other symptoms.
The light
must be suitably bright, (about the same as a spring morning
on a clear day), which must be between 5 and 20 times brighter
than a well-lit office. Contrary to belief, the light need
not be a special daylight match or 'full spectrum' type, and
simply changing the lamps in a room to these special types
will not produce sufficient light.
There are now many SAD light products available in the market,
the most popular being the lightbox. Other products include
alarm clocks with a light simulating dawn or a visor for those
with limited time to use the lightbox, and also portable products
for use even when exercising.
