Most of us rue the end of
summer—sunny days, mild nights, vacations, the beach, ball games, picnics and
so much more. Although fall and winter bring holidays, the warmth of a
fireplace and football (actual and fantasy), for many people the winter months
mark the return of seasonal depression.
It’s known in medical
circles as seasonal affective disorder (SAD), a
type of depression that affects a person during the same season each year. If
you get depressed in the winter but feel much better in spring and summer, SAD
may be the culprit. Symptoms typically start in September or October and end in
April or May.
Anyone can be affected by SAD, according to WedMD,
but it is most common in:
Women
People who live in areas
where winter days are very short or there are significant changes in the amount
of daylight in different seasons.
People between the ages of 15
and 55; the risk of SAD declines as we age.
People who have a close
relative with SAD. Like many other ailments, genetics can play a role.
Experts are not sure what causes SAD, but they suspect a
lack of sunlight, which may upset your
sleep patterns.
It also may cause problems with a brain chemical called serotonin that affects
mood. Symptoms may include feeling sad, moody and/or anxious; losing interest
in your usual activities; eating more and craving
carbohydrates, such as
breads and pasta;
gaining
weight, and sleeping more and feeling drowsy during the daytime.
Treatments
Doctors often prescribe
light therapy to treat
SAD. There are two types of light therapy:
Bright
light treatment. For this treatment, you sit in front of a “light box” for half
an hour or longer, usually in the morning.
Dawn
simulation. For this treatment, a dim light goes on in the morning while you
sleep, and it gets brighter over time, like a sunrise.
