Shorter days in winter can trigger seasonal affective disorder (SAD), a recurring form of depression associated with reduced sunlight. SAD is extremely common, affecting millions of Americans every year. Individuals in northern parts of the country, where there is less daylight, are generally affected more by SAD. Although the exact cause of SAD is unknown, many scientists believe the lack of sunlight creates a deficiency in vitamin D.
