Causes

The exact causes of SAD are unknown, but research suggests that hormones may trigger changes in mood at certain times of year. It correlates with vitamin D deficiency due to the lack of sunshine in the winter and fall that can cause the brain to produce less serotonin, a chemical responsible for regulating mood.

Other factors affecting mood may include changes in circadian rhythm and interference with the body's internal clock that regulates hormones and mood, due to lower levels of sunlight.
