What is SAD?
Seasonal Affective Disorder affects over 3 million Americans every year ranging from approximately 1 in every 100 people in Florida, to 1 in every 10 people in Alaska.
Causes of Seasonal Affective Disorder
The leading cause of SAD is the reduced level of sunlight offsetting your biological clock or circadian rhythm which typically comes within the fall and winter months.
Current Solutions for Seasonal Affective Disorder
Since the leading cause of SAD is the lack of sunlight, the popular remedy is light therapy through a lightbox which serves to mimic the natural sunlight. Light therapy has proven to be effective with the patient sitting a prescribed distance, commonly 1-2 ft in front of the light box, with the persons eyes open but not staring at the light source for approximately 30-60 minutes a day. However, while the addition of supplemental light in one’s daily life has proven to be the most effective remedy for SAD, up to 69% of patients find the lightbox treatment inconvenient and as many as 19% completely stop use because of this.
