Seasonal Affective Disorde
Some people feel sad or depressed during the winter months in northern
areas of the world. They may have trouble eating or sleeping. They suffer from a
condition known as Seasonal Affective Disorder, or S-A-D. Victims of S-A-D
suffer its effects during the short, dark days of winter. The problems are most
severe in the months when there are fewer hours of daylight. When spring
arrives, these signs disappear and S-A-D victims feel well again. The National
Mental Health Association reports that S-A-D can affect anyone. The group says
young people and women are at the highest risk for the disorder. It says that an
estimated 25 percent of the American population suffers from some form of S-A-D.
About 5 percent suffer from a severe form of the disorder. Many people in other
parts of the world also have the condition. The idea of health problems linked
to a lack of light is not new. Scientists have discussed the issue since the
beginning of medicine. More than two-thousand years ago, the Greek doctor
Hippocrates noted that the seasons affect human emotions. Today, experts do not
fully understand S-A-D, and yet they agree that it is a very real disorder. To
treat the disorder, victims of S-A-D do not need to wait until spring. Experts
know that placing affected individuals in bright light each day eases the
condition. There are other things people can do to ease the problem. They can
increase the sunlight in their homes and workplaces and spend more time outdoors
in the fresh air during the day. One study found that walking for an hour in
winter sunlight was as effective as spending two-and-one-half hours under bright
light indoors.
