DEC 7, 2014 — Vitamin D plays an important mood-regulating role in humans, a team of scientists has discovered.

An international team of scientists has found a link between the onset of Seasonal Affective Disorder — primarily a winter-time depression-like affliction — and lack of vitamin D.

Sunlight, a natural source of vitamin D, is not as abundant in winter months, especially in higher elevations where there may be increased cloud formations.

Alan Stewart of the University of Georgia, and his team, said one theory behind SAD is that reduced sunlight interferes with the body’s internal clock. The internal clock regulates sleep, hormones and mood.
