S.A.D. / Depression

Seasonal Affective Disorder (SAD), commonly known as "winter depression," is a type of depression that follows the seasons and is brought on by the reduction or lack of natural sunlight during winter months. Sleep changes, fatigue, altered appetite, depression, irritability, lethargy and physical problems such as headache, joint and stomach pain and low resistance to infection characterize SAD.

As many as six out of 100 people in the United States may experience winter depression. An additional 10%-20% may suffer mild SAD symptoms. SAD is more common in women than in men. Although SAD is not normally diagnosed in people younger than 20, some children and adolescents may experience symptoms.
The risk of SAD decreases as a person ages. SAD is more common in northern geographic regions. Susceptibility to SAD appears to be inherited.

Recent research indicates that utilizing bright light therapy, full spectrum light without the harmful UV rays, may have a beneficial effect on one's biological or circadian cycles and state of mind. This bright light therapy supplies a light that is up to 30 times more intense than traditional indoor lighting. Bright light therapy acts like virtual sunlight, easing the symptoms of SAD, when used on a regular basis as recommended by your physician.
