Drug rehab centers can help individuals suffering from substance dependency as a result of depression. However, depression is a seasonal condition for many Americans who live in regions of the country with a lack of sunlight throughout the winter months, according to Psychology Info, a statistics site.
Seasonal affective disorder (SAD) became a defined condition in the 1980s, according to the Los Angeles Times. Experts say that the winter blues arise when individuals are exposed to less sunlight, resulting in changes in appetite, sleep patterns and bouts of depression. However, new research shows that rates of SAD vary by region.
An estimated 2 percent of Floridians suffer from SAD every year where sunlight is abundant. In contrast, between 12 and 15 percent of Vermont residents report symptoms of SAD where daylight is limited. Andrew Winokur, director of psychopharmacology at the University of Connecticut, told the news source that studies on SAD rates tend to vary. However, everyone can benefit from a 30- to 60-minute walk under the sun during the winter months every day.
Light therapy is a common form of treatment for individuals suffering from SAD. Lamps specifically made for people with the disorder can reduce the symptoms throughout the winter months.
